DOI:  10.1007/s12225-017-9704-7 

Summary

A new species of Kalanchoe, Kalanchoe hypseloleuce Friis & M. G. Gilbert, was found during field work in Ethiopia in 2015, and is established here. It is characterised by its tall stature (2 – 3 m), entire, sessile, lanceolate leaves and pure white flowers with abaxially minutely papillose corolla lobes (otherwise, the plant is glabrous). It is not obviously related to any previously known species, but an earlier, incomplete specimen has been cited as K. prittwitzii Engl. in the literature. K. hypseloleuce was collected on limestone in Acacia-Commiphora woodland and bushland at c. 1400 m a.s.l. It occurs in the southern part of the eastern Ethiopian escarpment in the Arsi and Eastern Harerghe zones of the Oromo Regional State. K. hypseloleuce is documented with images and maps, its climate envelope has been modelled, and a conservation assessment made. With the current level of threat, this could be Vulnerable to Near Threatened (VU-NT). Given the threat from habitat degradation is not imminent, we recommend the species to be listed as Near Threatened (NT).

Key Words: Acacia-Commiphora bushland, Afromontane forest, conservation, limestone, monocarpic, taxonomy, transitional semi-evergreen bushland

ETYMOLOGY. Our new epithet, hypseloleuce, is a compound of two Greek adjectives. The first, ψηλός, ή, όν, ‘high, lofty, (metaphorically) stately’, refers to the impressive height of the plant, it being one of the tallest known species of Kalanchoe in Africa. The second, λευκός, -ή, -όν, ‘light, bright, (of colour) white’, refers to the pure white flowers. The connecting vowel –o– is in agreement with Rec. 60G(a2) of the Code (McNeill et al. 2012). The generic name, Kalanchoe Adans. (Adanson 1763: 248), is said to be an adaptation of a Chinese name for a species in the genus (Harvey 1862) or derived from a Hindi word ‘kalanka’, meaning ‘rust’ or ‘spot’ (Quattrocchi 2000). In botanical literature, Kalanchoe is treated as feminine and, in agreement with Art, 23.5 of the Code, the feminine form of the terminal adjective is used.

[Herpetology • 2019] Phrynobatrachus bibita • A New Species of Puddle Frog (Anura, Phrynobatrachidae) from An Unexplored Mountain in southwestern Ethiopia ---ScRaBBlE

 Phrynobatrachus bibita  

 Goutte, Reyes-Velasco & Boissinot, 2019

DOI: 10.3897/zookeys.824.31570 

Abstract

A new species of Phrynobatrachus is described from the unexplored and isolated Bibita Mountain, southwestern Ethiopia, based on morphological characters and sequences of the mitochondrial rRNA16s. The new species can be distinguished from all its congeners by a small size (SVL = 16.8 ± 0.1 mm for males, 20.3 ± 0.9 mm for females), a slender body with long legs and elongated fingers and toes, a golden coloration, a completely hidden tympanum, and a marked canthus rostralis. The phylogenetic hypothesis based on 16s sequences places the new species as sister to the species group that includes P. natalensis, although it is morphologically more similar to other dwarf Phrynobatrachus species, such as the Ethiopian P. minutus.

Keywords: Bibita Mountain, Ethiopia, morphology, phylogenetic relationships, Phrynobatrachus bibita sp. n., taxonomy

Phrynobatrachus bibita Goutte, Reyes-Velasco & Boissinot, sp. n.

Common name (English): Bibita Mountain dwarf puddle frog

Diagnosis: Small species (SVL = 16.8 ± 0.1 mm for males, 20.3 ± 0.9 mm for females) attributed to the genus Phrynobatrachus by the presence of tarsal and outer metatarsal tubercles (Suppl. material 2: Figure S1A). Body slender, with long legs (tibia length/SVL = 0.6 in both sexes) rather long snout for the genus and very elongated fingers (hand length/SVL = 0.3 in both sexes) and toes (foot length/SVL = 0.6 in both sexes) in comparison to its congeners. Webbing absent between fingers and minimal between toes. Tympanum not visible. Canthus rostralis marked and concave from nostril to eye. Snout pointed. Nostrils not visible from above. Eyelid spine absent. Throat of adult males white with light grey freckles on the anterior third, without any spinulae. Femoral glands hardly distinguishable but present in adult males. Two ridges in the scapular region and two short, oblique ridges behind the eyes. These four ridges may be all disjointed, the two scapular ridges may be jointed to form a chevron shape, or the ridges may be jointed laterally in an hourglass shape.

Etymology: The specific name refers to Bibita Mountain, the type and only known locality for the species. It is an invariable noun used in apposition.

Habitat, distribution, and natural history: All individuals were collected in a single large overgrown forest pond (Figure 3A), at night. The surrounding forest consisted of large trees with overhanging epiphytes and dense undergrowth. All females and the amplected pair were found on vegetation ca. 30 cm above water (Figure 3B). A single male was found in the water, presumably while calling. All collected females were gravid, and bicolor eggs were visible through the skin. Females seemed to aggregate in specific areas of the pond, were numerous egg clutches were found on leaves overhanging the water (Figure 3B). Laying eggs on vegetation overhanging the water is unusual in Phrynobatrachus, most species laying their eggs directly in the water (Zimkus et al. 2012). We thus confirmed that these eggs belonged to Phrynobatrachus bibita sp. n. by sequencing their mitochondrial rRNA 16s. Various forms of terrestrial egg deposition have been described in the genus Phrynobatrachus (Zimkus et al. 2012): most similarly to P. bibita, P. sandersoni (Parker, 1935) lays its eggs on vegetation up to 2 m above small puddles, small streams or water-saturated soil (Amiet 1981) and P. krefftii lays its eggs above the water, on rocks or vegetation (Harper and Vonesh 2010). Phrynobatrachus guineensis Guibé & Lamotte, 1961 lays its eggs on the bark of trees above water-filled tree holes (Rödel 1998) and P. dendrobates lays its eggs in tree holes or above streams (Zimkus et al. 2012). Finally, P. phyllophilus Rödel & Ernst, 2002, P. tokba (Chabanaud, 1921), and P. villiersi Guibé, 1969 lay their eggs on the leaf litter or the forest floor (Rödel and Ernst 2002a, 2002b; Zimkus et al. 2012). Phrynobatrachus bibita sp. n. thus adds to the diversity of reproductive modes in the genus.

[Ichthyology • 2018] Molecular Phylogenetic Analysis of the Catfish Species Auchenoglanis occidentalis (Valenciennes, 1840) (Pisces: Claroteidae) from Lake Turkana in East Africa: Taxonomic Iimplications. ---ScRaBBlE

 in Okwiri, Cao, Nyi & Zhang, 2018. 

  DOI: 10.11646/zootaxa.4450.1.8 

Abstract

Cytochrome c oxidase subunit I (COI) gene sequences of two specimens here recognized as Auchenoglanis occidentalis from Lake Turkana in the Ethiopian section were determined. A COI gene-based phylogenetic analysis was performed for these along with sequences of African catfish species from the family Clarotidae available in GenBank. Based on results of this analysis, it is concluded that (1) the currently identified A. occidentalis is a species complex that includes several distinct species; (2) the Niger River basin harbors two distinct species of Auchenoglanis, one of which occurs in Lake Turkana, as well as A. biscutatus; and (3) A. sacchii is likely a valid species, but it is not the endemic species of Lake Turkana. It is suggested here that species diversity of Auchenoglanis requires further study based on molecular and morphological evidence.

[Mammalogy • 2018] Ethiopian Highlands as A Cradle of the African Fossorial Root-rats (Genus Tachyoryctes), the Genetic Evidence ---ScRaBBlE

Šumbera, Krásová, Lavrenchenko, et al., 2018.

  DOI: 10.1016/j.ympev.2018.04.003 

 Highlights

• Six major genetic clades do not correspond to the expected two or 13 root-rat species.

• Ethiopian, and not Kenyan, highlands are the cradle of the genus diversity.

• Root-rat history was shaped by climatic oscillations and complex geomorphology.

• The giant root-rat is an internal lineage of the genus modified for life in the Afroalpine.

• Root-rats and mole-rats represent different specialisations for the subterranean niche.

Abstract

Root-rats of the genus Tachyoryctes (Spalacidae) are subterranean herbivores occupying open humid habitats in the highlands of Eastern Africa. There is strong disagreement about species diversity of the genus, because some authors accept two species, while others more than ten. Species with relatively high surface activity, the giant root-rat Tachyoryctes macrocephalus, which is by far largest member of the genus, and the more fossorial African root-rat Tachyoryctes splendens, which eventually has been divided up to 12-13 species, represent two major morphological forms within the genus. In our study, we carried out a multilocus analysis of root-rats’ genetic diversity based on samples from 41 localities representing most of Tachyoryctes geographic distribution. Using two mitochondrial and three nuclear genes, we found six main genetic clades possibly representing separate species. These clades were organised into three basal groups whose branching is not well resolved, probably due to fast radiation in the late Pliocene and early Pleistocene. Climatic changes in that time, i.e. fast and repeated changes between extremely dry and humid conditions, which both limited root-rat dispersal, probably stimulated their initial genetic diversification. Contrary to expectation based on the largest root-rat diversity in Kenya (up to eight species by some authors), we found the highest diversity in the Ethiopian highlands, because all but one putative species occur there. All individuals outside of Ethiopia belong to a single recently diverged and expanded clade. This species should bear the name T. annectens (Thomas, 1891), and all other names of taxa described from outside of Ethiopia should be considered its junior synonyms. However, to solve taxonomic issues, future detailed morphological analyses should be conducted on all main clades together with genetic analysis of material from areas of their supposed contact. One of the most interesting findings of the study is the internal position of T. macrocephalus in T. splendens sensu lato. This demonstrates the intriguing phenomenon of accelerated morphological evolution of rodents occupying the Afroalpine zone in Ethiopia. Finally, we discuss how the distribution of Tachyoryctes is influenced by competition with another group of subterranean herbivores on the continent, the African mole-rats. We assume that both groups do not compete directly as previously expected, but specialisation to different subterranean niches is the main factor responsible for their spatial segregation.

Keywords: Tachyoryctes; fossorial rodent; Eastern Africa; Plio-Pleistocene climatic changes; Great Rift Valley; multi-species coalescent

 Conclusion: 

Contrary to the expectation that root-rats have their highest species diversity in the Kenyan highlands, our results convincingly demonstrated that the Ethiopian mountains are the centre of genus diversity and the cradle of the whole group. The evolution of extant root-rats took place in the Pleistocene and was affected mainly by the interplay between climate changes and the complex geomorphology, with the presence of high mountain massifs, in Ethiopia. Root-rat genetic structure in Ethiopia suggests several cryptic species that should be explored in future taxonomic work, because it is clear that current taxonomy does not reflect the evolutionary history of the genus at all. Probably all taxa described from outside Ethiopia are descendants of a single relatively recent “out-of-Ethiopia” dispersal event and should be considered as conspecific. The fact that the largest and morphologically most deviating species, T. macrocephalus, is not a sister but an internal lineage of “splendens” is further evidence of a fast morphological evolution in response to strong selection in the Afroalpine environment in Ethiopia. We may expect that more thorough genetic surveys of unique Afroalpine taxa will reveal more such findings not only in mammals, but also in other groups of vertebrates. Finally, ecological, behavioural and physiological studies could reveal how the distribution of root-rats is influenced by competition with the African mole-rats, another group of African rodents with subterranean habits.

  DOI:  10.3897/phytokeys.97.20975 

Abstract

A revision of the 45 species of the pantropical genus Xylopia in Tropical Africa includes descriptions of six new species and a new section of the genus. The fruits and seeds of Xylopia show specializations that promote vertebrate dispersal, primarily by hornbills and monkeys. Over half of the African species have an Area of Occupancy (AOO) less than 80 km2, suggesting that they are in need of protection. African species are classified into five sections. Section Neoxylopia , with four species, is centered in the Guineo-Congolian Region and includes Xylopia globosa sp. nov. Section Ancistropetala, with three species, occurs in the same region. Both of these sections are endemic to Africa. Section Xylopia, which extends to Madagascar and the American tropics, has only a single species in Africa, X. aethiopica. The three species of section Verdcourtia sect. nov. are restricted to the East African coast and Madagascar. The largest number of African species, (34) belong to section Stenoxylopia, in which the seeds lack the arils found in the other sections and instead have a fleshy sarcotesta. Section Stenoxylopia is divided into two informal groups, one centered in eastern and southern Africa (X. odoratissima group) and the other centered in the wetter forests of western and central Africa (X. acutiflora group). Five new species are described in section Stenoxylopia: Xylopia nilotica sp. nov. from Sudan, South Sudan, and Uganda, Xylopia calva sp. nov. from Nigeria and Cameroon, which is allied to X. phloiodora, and Xylopia monticola sp. nov. from Nigeria and Cameroon, X. piratae sp. nov. from Ivory Coast and Ghana, and X. unguiculata sp. nov. from Gabon. The latter three species are segregates of the former Xylopia acutiflora s. l. One new combination is made at the species level, X. shirensis comb. nov. Keys, descriptions, illustrations, distribution maps, and an index to numbered collections document diversity and assist with species identification. The name Unona oliveriana Baill. was found to pre-date the name Unona lepidota Oliv., requiring the combination Meiocarpidium oliverianum comb. nov.

[Mammalogy • 2017] On the Taxonomy of Erythrocebus with A Re-evaluation of Erythrocebus poliophaeus (Reichenbach, 1862) from the Blue Nile Region of Sudan and Ethiopia ---ScRaBBlE

Erythrocebus poliophaeus  (Reichenbach, 1862) 

in Gippoliti, 2017.

 Primate Conservation. 31; 53-59. 

Abstract

 Erythrocebus taxonomy has been dormant for almost a century now, with the consequent costs in our understanding of the biology of the genus and for the conservation of these remarkable monkeys. New data on the distribution and physical appearance of patas monkeys in Ethiopia, together with a review of the old taxonomic literature, allows to us disentangle some questions concerning the taxonomy of Erythrocebus in northeast Africa. Specifically, I resurrect Erythrocebus poliophaeus (Reichenbach, 1862) as a valid species that is found along the Blue Nile Valley at the extreme northeastern portion of the range of the genus. The still little-known, but certainly limited, extent of the range of the species is a cause for conservation concern, but it may be that Erythrocebus poliophaeus could serve as a flagship species for conservation in the biologically rich Western Ethiopian Escarpment region and adjoining Sudan. The proposed common English names for the new species are Heuglin’s patas monkey (Heuglin was the famous German explorer who discovered it) or the Blue Nile patas monkey.

....

Conclusions: 

As anticipated by Allen (1925), some of the named forms of Erythrocebus could be valid taxa if more evidence came to light. The main aim of the article was to revive interest in the topic and highlight some conservation priorities in East Africa. A species first described over 150 years ago is re-evaluated; it is known from the Blue Nile basin in western Ethiopia and adjoining Sudan, and separated from another Erythrocebus taxon by the Sudd swampy region in Sudan and the Ethiopian highlands, which stretch up to the Sudanese border north of Gambela. It is an obvious focus for further research and conservation. Monkeys of the genus Erythrocebus are potential flagships for important African ecosystems, and may well be at greater risk than is generally believed. 

The western Ethiopian escarpment flora has received due scientific attention only in this century, and a number of new endemic species have been discovered in Benshangul Gumuz in recent years (Sebsebe Demissew et al. 2005). A revised taxonomy of the genus Erythrocebus is also fundamental to analyze the available data concerning the natural history and biology of the different taxa. With the recognition of the Heuglin or Blue Nile patas monkeys Erythrocebus poliophaeus we have now two taxa with a black face and nose (at least in the adult male)—the other being Erythrocebus baumstarki— at the fringe of the genus’s range in East Africa, and possibly representing ancient surviving lineages that have been supplanted by a white-nosed species elsewhere in East Africa that is provisionally referred as Erythrocebus pyrrhonotus, with E. p. formosus and a number of other subspecies occurring over its range
