[Entomology • 2016] Revision of the Oriental subfamily Heteropteryginae Kirby, 1896 (Phasmatodea: Areolatae: Heteropterygidae), with A Re-arrangement of the family Heteropterygidae and the Descriptions of Five New Species of Haaniella Kirby, 1904 ---ScRaBBlE


Heteropteryx dilatata  (Parkinson, 1798)


Abstract  

The areolate Oriental family Heteropterygidae Kirby, 1893 is critically reviewed and the results of the present study contradict the arrangement suggested by Zompro (2004), but in most aspects agree with a molecular study presented by Whiting et al (2003) and a phylogenetic study presented by Bradler (2009). The family is critically discussed and new hypotheses are presented for the phylogeny and intra-familiar relationships, placing the subfamily Dataminae Rehn & Rehn, 1939 as the basalmost clade of Heteropterygidae. The subfamilies Obriminae Brunner v. Wattenwyl, 1893 and Heteropteryginae Kirby, 1893 together represent the sister-group of Dataminae. Arguments and a tree are presented to support this hypothesis. New diagnoses and lists of genera are provided for all three subfamilies contained in Heteropterygidae, along with keys to distinguish between them.

        The subfamily Obriminae is critically reviewed and the distinction between the three tribes Obrimini Brunner v. Wattenwyl, 1893, Eubulidini Zompro, 2004 and Miroceramiini Zompro, 2004 introduced by Zompro (2004) is shown to be poorly supported. While Obrimini sensu Zompro, 2004 is generally accepted (but now also contains genera that were placed in Eubulidini or Miroceramiini by Zompro (2004)), the tribes Eubulidini and Miroceramiini are not supported. A new arrangement is introduced, which is based on morphological characters neglected or overlooked by Zompro (2004) but were partly discussed by Bradler (2009). The genus Mearnsiana Rehn & Rehn, 1939 is removed from Miroceramiini and transferred to Obrimini. The genera Eubulides Stål, 1877Heterocopus Redtenbacher, 1906Theramenes Stål, 1875 and Stenobrimus Redtenbacher, 1906 are removed from Eubulidini and also transferred to Obrimini. Consequently, Eubulidini is synonymised with Obrimini (n. syn.). Miroceramiini is a monotypical tribe and only includes the Wallacean genus Miroceramia Günther, 1934. The new tribe Tisamenini n. trib. is established for the three basal genera Tisamenus Stål, 1875Ilocano Rehn & Rehn, 1939 and Hoploclonia Stål, 1875 all of which were placed in Eubulidini by Zompro (2004). The latter genus differs from the other two genera by the morphology of the female genitalia, which is unique amongst the entire family. Three generic groups are recognized within Obrimini, the Obrimus-group, Stenobrimus-group and Theramenes-group. Keys are presented to distinguish between the three tribes now contained in the Obriminae, i.e. Obrimini, Tisamenini n. trib. and Miroceramiini. The genus Hennobrimus Conle, 2006 is synonymised with Mearnsiana Rehn & Rehn, 1939, based on the fact that the type-species of both genera are conspecific (n. syn.). Hennobrimus hennemanni Conle, 2006, the type-species of Hennobrimus, and Trachyaretaon manobo Lit & Eusebio, 2005 are synonymised with Mearnsiana bullosa Rehn & Rehn, 1939, the type-species of Mearnsiana (n. syn.). Theramenes dromedarius Stål, 1877 from the Philippines is removed from synonymy with the Wallacean Theramenes olivaceus (Westwood, 1859) and re-established as a valid species (rev. stat.).

        The subfamily Heteropteryginae Kirby, 1896 is revised at the species-level and a new diagnosis is presented. Keys to the two genera and all 16 known species are provided along with new descriptions, differential diagnoses, lists of examined material, detailed information on the known distributions, measurements and illustrations of the insects and eggs. The intra-subfamiliar and intra-generic relationships are discussed and a cladogram is presented. Heteropteryginae contains two genera: Heteropteryx Gray, 1835 (Type-species: Phasma dilatatum Parkinson, 1798) and Haaniella Kirby, 1896 (Type-species: Phasma (Heteropteryx) muelleri de Haan, 1842). The distribution of this subfamily is restricted to Sundaland with the exception of a single species that is found in Vietnam. All other species are distributed in Borneo, Sumatra, the Mentawai Islands, Singapore, Peninsular Malaysia and Thailand. Heteropteryginae contains the largest and most striking members of the entire family Heteropteryginae, some of which are amongst the heaviest insects known. The subfamily is characterized by apomorphies such as the presence of wings, having a tympanal area (= stridulatory organ) in the basal portion of the alae, straight profemora, strongly shortened tarsi, lack of rough sensory-areas on the prosternum and typically X-shaped micropylar plate of the eggs. The sister-group of Heteropteryginae is represented by the Obriminae, with which it shares a beak-like secondary ovipositor in the females and presence of a medio-apical spine on the area apicalis. Both features are synapomorphies of Heteropteryginae + Obriminae.

        The genus Haaniella Kirby, 1904 contains 16 known species, five of which are newly described herein. The genus Miniopteryx Zompro, 2004 (Type-species: Haaniella parva Günther, 1944) is synonymised with Haaniella on the basis that the distinguishing feature mentioned in the original description is a character that is frequently found throughout the genus (n. syn.). The type-species H. parva Günther, 1944 is automatically retransferred to Haaniella (rev. stat.). Haaniella aculeata n. sp. from western Sumatra is described from the male. Haaniella macroptera n. sp. from Singapore and the Johor state in southern Peninsular Malaysia is described from both sexes and the eggs. Haaniella gintingi n. sp. from Central Sumatra is described from both sexes and the eggs and Haaniella kerincia n. sp. from Western Sumatra is described from the insects only, the eggs being still unknown. One new species, Haaniella gorochovi n. sp., is the only representative of the genus and subfamily Heteropteryginae known from Vietnam and both sexes as well as the eggs are described. Haaniella erringtoniae (Redtenbacher, 1906) is endemic in Peninsular Malaysia, here removed from synonymy with H. muelleri (de Haan, 1842) and re-established as a valid species (rev. stat.). The Sumatran Haaniella glaber (Redtenbacher, 1906) is removed from synonymy with H. muelleri (Haan, 1842) and re-established as a valid species (rev. stat.). Leocrates glaber Redtenbacher, 1906 and Haaniella muelleri simplex Günther, 1944 are removed from synonymy with H. muelleri (Haan, 1842) (rev. stat.) and synonymised with H. glaber. Haaniella mecheli (Redtenbacher, 1906) and H. rosenbergii (Kaup, 1871) are removed from synonymy with H. muelleri (Haan, 1842) and re-established as valid species (rev. stat.). Haaniella erringtoniae novaeguineae Günther, 1934 and Haaniella muelleri var. b. (Haan, 1842) are synonymized with H. rosenbergii (Kaup, 1871) (n. syn.). The type-species Haaniella muelleri (Haan, 1842) is shown to be a fairly rare species that is restricted to Sumatra. All subsequent records of H. muelleri from outside Sumatra and references to captive breeding of stock originating from Peninsular Malaysia in Europe relate to H. erringtoniae (Redtenbacher, 1906). The previously unknown males and eggs of H. rosenbergii (Kaup, 1871) as well as the previously unknown females and eggs of H. parva Günther, 1944 are described and illustrated for the first time. Based on morphological characters of the insects and eggs three distinct species-groups are recognized within Haaniella. The muelleri species-group contains nine species that are distributed throughout Sumatra, the Mentawei Islands, Singapore and Peninsular Malaysia. These are characterized by the smooth ventral surface of the meso- and metafemora and lemon-shaped eggs which entirely lack the setae seen in the two other species-groups. The grayii species-group comprises four species, two of which are endemic in Borneo, one endemic in Sumatra and the fourth species being the only known representative of the subfamily in Vietnam. These species are characteristic for the prominent pair of spines on the abdominal tergites II–IV of males and long apically multidentate epiproct of females. The echinata species-group contains three exceptionally Bornean species, which are characterized by the long and apically pointed subgenital plate of females, which clearly projects beyond the epiproct, as well as the sub-basal lateral tooth of the anal segment of males. The muelleri species-group is sister to the remainder two species-groups.

        Heteropteryx Gray, 1853 is a monotypical genus and only contains the type-species H. dilatata (Parkinson, 1798), which is found throughout Peninsular Malaysia, Thailand, Sumatra and Northeastern Borneo. This genus differs from Haaniella by the strongly conically elevated head, which posteriorly projects over the anterior margin of the pronotum, females being bright green or yellow in colour with plain and translucent pink alae and having distinct spines on the abdominal tergites, and males having a strongly shortened mesothorax and dull pink alae. 

Lectotypes are designated for Haaniella parva Günther, 1944, Heteropteryx echinata Redtenbacher, 1906, Heteropteryx saussurei Redtenbacher, 1906 and Heteropteryx scabra Redtenbacher, 1906 to guarantee stability of these names.

        Information on the habitats, host-plants, biology, life cycle, parasitism and captive breeding of the species of Heteropteryginae is presented and a list summarising all taxonomic changes presented herein.

[Herpetology • 2017] Tytthoscincus temasekensis • A New Species of Swamp-dwelling Skink (Tytthoscincus) from Singapore and Peninsular Malaysia ---ScRaBBlE


 Tytthoscincus temasekensis
 Grismer, Wood, Lim & Liang, 2017 

RAFFLES BULLETIN OF ZOOLOGY65 

Abstract

 Tytthoscincus temasekensis is a new species of swamp-dwelling skink from Singapore and the vicinity of Tanjung Malim, Perak, Peninsular Malaysia and the third species in the swamp clade of Tytthoscincus. It is distinguished from all other species of Tytthoscincus by the combination of having two loreals; two postsupralabials; 10–12 superciliaries; four supraoculars; interparietal contacting the 2nd–4th supraoculars; a shallow, pigmented tympanum; slightly enlarged, isolated, pectoral scales; 27–29 midbody scale rows; 55–65 paravertebral scales; 54–63 ventral scales; 9–11 subdigital lamellae on the fourth toe; keeled, subdigital lamellae; and a dorsal pattern of light-coloured stripes and/or linearly arranged spots. The growing diversity of the swamp clade in Singapore and Peninsular Malaysia begins to underscore the underappreciated contribution of swamplands to herpetological endemism and diversity as well as the need for its conservation.

 Key words. Scincidae, Tytthoscincus, Singapore, Malaysia, swamp forests, new species

Fig. 2. Tytthoscincus temasekensis sp. nov.  adult holotype (ZRC 2.6490) from Pasir Laba Road, Singapore.; juvenile paratype (ZRC 2.7111) from Upper Seletar Reservoir Park, Singapore (Photograph by Nick Baker).

TAXONOMY 

The molecular and morphological data indicate thus far that the Tytthoscincus populations from Singapore and Tanjung Malim are conspecific and well-differentiated from T. sibuensis and T. panchorensis. They are therefore described below as:

 Tytthoscincus temasekensis, new sp.

Diagnosis. Tytthoscincus temasekensis sp. nov. can be differentiated from all other species of Tytthoscincus in Peninsular Malaysia by having the combination of two loreals, two postsupralabials, 9`1 or 10`2 superciliaries, four supraoculars; interparietal contacting 2nd–4th supraoculars, a shallow, pigmented tympanum, slightly enlarged pectoral scales, 27–29 midbody scale rows, 55–65 paravertebral scales, 54–63 ventral scales, 9–11 subdigital lamellae on the fourth toe, keeled, subdigital lamellae, and a dorsal pattern of light-coloured stripes and/or linearly arranged spots. All characters are scored across all other Tytthoscincus and species of Sphenomorphus suspected of being Tytthoscinus in Grismer et al. (2016a: 237) and Karin et al. (2016: 416).

Non-types. Tytthoscincus temasekensis. ZRC 2.3277 (juvenile) from North Selangor Peat Swamp kilometer marker 34 on road to Tanjung Malim, Selangor, Peninsular Malaysia (approximately N 03°42.383′, E 101°09.115′; 20 m elevation) collected by NUS 1991–92 Zoology Honours Class on 17 June 1991. ZRC 2.3377 (juvenile) from North Selangor Peat Swamp kilometer marker 47 at Sungai Besar Road on road to Tanjung Malim, Selangor, Peninsular Malaysia (approximately N 03°41.472′, E 101°14.062′; 15 m elevation) collected by D. S. L. Chung in April 1993. ZRC 2.7152 from the Nee Soon swamp-forest, Singapore collected by H. H. Tan and others on 23 October 1999.

Distribution. Tytthoscincus temasekensis, new species, is known from lowland areas in Singapore and near Tanjung Malim, Perak, Peninsular Malaysia (Fig. 1). Natural history. Tytthoscincus temasekensis has been found in lowland dipterocarp forests but is far more common along stream banks in peat and freshwater swamp forests up to at least 37 m in elevation (Lim, 1998; Serin, 2015; Fig. 3). Specimens near Tanjung Malim were inadvertently collected while hand-netting for fishes in small streams which may indicate semi-aquatic proclivities as noted by Baker (2013) who states “An example of about 5 cm was seen among forest leaf litter at the edge of a shallow stream. It swam in a sinuous motion across the stream, coming to rest on the opposite side partly submerged, with only the front part of its head including the eyes and nostrils emerged.” ZRC 2.7111 was collected while crossing a paved road running through lowland forest. A juvenile (ZRC 2.6859) was taken from the gut of an Aheatulla mycterizans found dead on Old Upper Thomson Road.

 Etymology. The specific epithet temasekensis is derived from the word Temasek meaning ‘Sea Town’ in Old Javanese and represents the earliest recorded name of a settlement in Singapore. The suffix -ensis is Latin meaning ‘of or from a place.’ The specific epithet is in reference to the type locality being on the island of Singapore. The suggested common name is the Singapore swamp skink.

Abstract
The globally threatened Straw-headed Bulbul Pycnonotus zeylanicus is one of South-East Asia’s most imperiled songbirds due to the surging demand for the species in the regional bird trade. Recently uplisted from Vulnerable to Endangered, populations of the Straw-headed Bulbul have been extirpated from Java, Thailand and possibly Sumatra while those in Borneo and Peninsular Malaysia are in decline. Intriguingly, a significant yet rarely documented population of this species persists in Singapore. A major stronghold in Singapore is Ubin Island where a population is known since the 1920s. Using a long-term citizen science dataset rarely available for South-East Asian bird species, we determined the status and population trends of the Straw-headed Bulbul in Singapore over a 10–15 year period using Poisson regression models and standardised population indices. We found that the Straw-headed Bulbul population has increased at a rate of 3.69 ± 1.21% per annum on Ubin Island, while the population on Singapore Island remained stable (0.56% per annum) from 2000 to 2016. The population trends in Singapore contrast starkly with the declines reported elsewhere in South-East Asia. We estimated the population in Singapore to be a minimum of 202 individuals, distributed over multiple forest patches. The largest subpopulation of about 110 adult individuals persists on Ubin and which alone forms between 6.5–18.3% of the estimated global population in 2016. Given this unique situation, we recommend a number of conservation measures for the Straw-headed Bulbul to better protect the species, including: (1) an expansion of the protected area network in Singapore to include Ubin as a reserve, (2) the development of an endangered species management plan and, (3) the establishment of ex-situ conservation programmes in zoological institutions and wildlife centres in the region.

Abstract
A new species of wolf spiders, Ovia macritchie sp. nov., is discovered in Singapore. It is closely related to O. procurva (Yu & Song, 1988), hitherto the only species of Ovia Sankaran, Malamel & Sebastian, 2017. O. macritchie also resembles Pardosa alboannulata Yin et al., 1997 from China, which is herein transferred to Ovia. All of them share a uniquely hooked terminal apophysis on the male pedipalp. Colour photos, line drawings, SEM photos and detailed descriptions are provided for both the new species O. macritchie and the newly combined species O. alboannulata.

Keywords: Araneae, Pardosa, diversity, taxonomy, copulatory organs

Ovia macritchie sp. nov. 

Etymology. The specific epithet is a noun in apposition and refers to the type locality, which is commonly known as the “MacRitchie Forest” within the species-rich Central Catchment Nature Reserve in Singapore. The name of this forest is becoming a catch-phrase epitomizing an evolving habit towards constructive engagement, in the spirt of mutual respect, among government agencies, the scientific community and civil society seeking to finetune a balance between safeguarding the shared natural heritage of all Singaporeans and meeting the infrastructure needs in land-scarce Singapore.

[Arachnida • 2018] Cyclosa bulla • A New Species of Cyclosa (Araneae: Araneidae) from Southeast Asia ---ScRaBBlE


Cyclosa bulla  
Tanikawa & Petcharad, 2018


Abstract
A new species of Cyclosa is described under the name of Cyclosa bulla n. sp. using specimens collected from Thailand, Singapore and Brunei. Females of the species can be easily distinguished from other congeners by the shape of the abdomen, which has a globose posterior end. In contrast, males cannot be distinguished from those of Cyclosa bifida, which seems to be the most closely related species, even by the shape of the palpal organ. In this study, male specimens are identified by DNA barcoding.

Keywords: Cyclosa bulla, taxonomy, COI, barcoding, Thailand, Singapore, Brunei


 Cyclosa bulla n. sp. 
A, female (holotype), dorsal view; B, same, lateral view; C, paratype (male), dorsal view..
 Scales: A–C, 1 mm.

Cyclosa bulla new species 
[Thai name: Mangmoum-Taai-Klom-Cyclosa]

Diagnosis. The new species seems to be closely related to Cyclosa bifida, but females can be easily distinguished from Cyclosa bifida by the posteriorly globose abdomen (Figs. 2A–B). Males of these species cannot be separated morphologically, even by the shape of the palpal organ. Male specimens of the new species can be identified only by DNA sequencing data, e.g. mt-COI.

Etymology. The specific name is derived from the knob-like shaped posterior part of the abdomen; “bulla” is a Latin word that means “globe”.
