Abstract

The beach-hopper and land-hopper genus Floresorchestia Bousfield, 1984 is most widespread in terrestrial and marine littoral habitats and has been recorded from the South African coasts through to tropical Indo-Pacific and Caribbean Sea. In Thailand, there is only Floresorchestia samroiyodensis Azman, Wongkamhaeng & Dumrongrojwattana, 2014 reported from the swamp of Prachuab Kiri Khan, southern Thailand. In this work, two new species of Floresorchestia from Phutsa Reservoir in Nakhon Ratchasima and the man-made swamp in Burapha University are described. The new species are characterised by the mandible left lacinia mobilis 4-dentate; the posterior margin of merus, carpus and propodus covered in palmate setae; the uropod 3 peduncle with two robust setae and the telson longer than broad. The characters of the specimens are described and illustrated in this paper. All specimens are deposited in the Princess Maha Chakri Sirindhorn Natural History Museum, Prince of Songkla University, Thailand.

"กุ้งเต้นบูรพา (Floresorchestia buraphana Wongkamhaeng, Dumrongrojwattana and Pattaratumrong, 2016)" และถิ่นอาศัย (Burapha's land-hopper and its habitats)

ตัวอย่างของ new species ที่อยู่รอบ ๆ ตัวเรา ชื่อ F. buraphana นี้ตั้งเพื่อเป็นเกียรติแก่ มหาวิทยาลัยบูรพาในวาระรอบ 60 ปี และก้าวย่างสู่ปีที่ 61 และในฐานะที่เป็นสถานที่ที่พบกุ้งเต้นชนิดใหม่นี้ครั้งแรกของโลก รวมถึงเป็นที่ที่ทำให้มีวันนี้

Fantastic Burapha land-hopper (Floresorchestia buraphana) and where to find them. Our fellows may enjoy searching for the alive amphipod in their real habitat as the marks in the map together with breathing the warm winter.

[Botany • 2018] Miliusa chantaburiana (Annonaceae) • A New Species from southeastern Thailand ---ScRaBBlE

Miliusa chantaburiana Damthongdee & Chaowasku

in Damthongdee & Chaowasku, 2018.

ระฆังจันท์ || DOI: 10.3372/wi.48.48208

Abstract

Miliusa chantaburiana Damthongdee & Chaowasku, a new species of Annonaceae from SE Thailand, is described and illustrated. It belongs to a clade with campanulate flowers and inner petals that are generally tightly appressed from the base to more or less the midpoint at anthesis. The new species is remarkable in possessing a strongly recurved apex of the inner petals at anthesis and can be principally differentiated from its morphologically closest species, M. pumila Chaowasku and M. filipes Ridl., both from Peninsular Thailand, by the higher number of stamens and carpels per flower and horseshoe-shaped stigmas. Miliusa chantaburiana is also unique in having a 6-base-pair insertion in the plastid matK sequence. A revised key to species in the campanulate-flowered clade in Thailand is given.

Miliusa chantaburiana Damthongdee & Chaowasku, sp. nov.

Holotype: Thailand, cultivated in Bangkok [sapling originally from Khiri Than Dam, Chantaburi Province], 7 Feb 2015 [in flower], Nakorn-Thiemchan NTC 29 (CMUB!; isotypes: B!, P!).

Diagnosis — Miliusa chantaburiana is morphologically close to M. pumila and M. filipes, both occurring in Peninsular Thailand (Chaowasku 2014). The new species differs mainly from M. pumila by having generally larger leaf blades ([9.2–] 12.2–18[–19.5] x [2.8–]3.3–6 cm vs 5.4–10.5 x 2–4.1 cm), generally longer pedicels ([11–] 14–22[–30] mm vs 5–11 mm), more stamens per flower (48–50 vs 38–39), and many more carpels per flower (49–71 vs 12–13). The new species primarily differs from M. filipes by possessing considerably more stamens (48–50 vs c. 22) and carpels (49–71 vs c. 16) per flower. In addition, M. chantaburiana exhibits horseshoe-shaped stigmas, whereas they are subglobose to ellipsoid(-obovoid) in M. pumila (Chaowasku 2014) and capitate in M. filipes.

Distribution and ecology (at original locality) — Chantaburi Province, SE Thailand (Fig. 4); occurring in partially disturbed evergreen forests around a constructed dam; at an elevation of c. 205 m.

Conservation status — This species is known only from a very restricted area, i.e. around Khiri Than Dam of Chantaburi Province, SE Thailand (Fig. 4). Fewer than 10 individuals were observed in the area, some of which occur adjacent to the reservoir and could be submerged in the near future, and it is believed that many more individuals have been submerged during dam construction. Further, this species has never been reported to occur in nearby areas (e.g. Khao Khitchakut National Park, Khao Soidao Wildlife Sanctuary, Namtok Phliu National Park and Namtok Khlongkaew National Park) and no specimens have been collected prior to the present study. Based on this information, Miliusa chantaburiana is undoubtedly a rare species; however, we believe that more exploratory data, especially from Cambodia (which is merely c. 20 km away from the dam), are required prior to the assessment of the conservation status of this species. Therefore, it is considered here as Data Deficient (DD) (IUCN 2012).

Etymology — The epithet refers to Chantaburi, the SE Thai province where this species is endemic.
