This article is the second part of a revision of the systematics of Boaedontini Dowling, 1969 and a follow-up to the work by Tiutenko et al. (2022). As a result of morphological and phylogenetic analyses, further taxonomic actions are taken in the genus Lycodonomorphus Fitzinger, 1843. Lamprophis inornatus Duméril, Bibron & Duméril, 1854, a species...

Lamprophis erlangeri is a lamprophiid snake endemic to moist montane forest remnants and formerly forested areas in the south and south-west of the Ethiopian highlands. Its vernacular name ‘Ethiopian House Snake’ is a result of century-long speculations about the generic placement of this species. New molecular and morphological data brought eviden...

The members of the Afrotropical lacertid genus Holaspis are strikingly specialized lizards, adapted for gliding in forest canopies, with serrated blue tails. Two species are currently recognized within the genus: Holaspis guentheri from West and Central Africa, and Holaspis laevis from East Africa. The currently known southern limits of H. guenther...

Apostolepis is a diverse genus of small and fossorial dipsadid snakes, comprising 34 species ranging from Colombia southwards into Argentina. Most species are known from small series and very little is known regarding their phylogenetic relationships, morphological variation and diagnoses, which has caused a widespread historical taxonomic instabil...

The genus Rhoptropus comprises nine recognized species of diurnal geckos endemic to the arid regions of Angola and Namibia. Seven species occur in Angola, including the widespread R. boultoni and the poorly known Angolan endemics R. benguellensis and R. montanus, formerly recognized as subspecies of R. boultoni. While R. benguellensis is relatively...

Four species of the genus Panaspis – P. cabindae, P. wahlbergii, P. maculicollis and P. mocamedensis – are currently known from Angola. The analysis of recently collected specimens from Serra da Neve Inselberg, an isolated mountain located in northern Namibe Province, revealed unexpected taxonomic diversity in the group. Using an integrative taxono...

The Serra da Neve inselberg in Namibe Province, southwestern Angola is the second highest peak of Angola with an elevation of 2489 m. It remains one of the least explored regions in the country, despite several endemic species having been recently described from this inselberg. Here we provide an inventory of the amphibian and reptile species ocurr...

The genus Trachylepis is currently represented by 21 species in Angola, most of them part of nomenclaturally and taxonomically challenging species complexes. In this study we present an integrative taxonomic revision of the genus in Angola and describe seven new species: Trachylepis attenboroughi, sp. nov., Trachylepis bouri, sp. nov., Trachylepis...

During a recent survey of the Serra da Neve inselberg in southwestern Angola, a population of legless skinks of the genus Acontias was found. Only three species of this genus have been recorded for the country so far – A. occidentalis, A. kgalagadi and A. jappi. Using an integrative approach and combining molecular and morphological data we found t...

The tadpole of Leptopelis diffidens is described to complete the data on this new species whose description was published a year earlier. It is compared with the tadpoles of sympatric and parapatric congeners – L. ragazzii and L. shebellensis. The description of the latter is extended and corrected. Hypotheses about breeding seasonality of L. diffi...

The Sharp-nosed Reed Frogs (Hyperolius nasutus Günther, 1865 sensu lato) are a complex of species widespread in savannah regions of sub-Saharan Africa, from the Ivory Coast (Schiøtz, 1999) to southern Somalia (Lanza, 1981, 1990), and southwards to the KwaZulu- Natal lowlands of South Africa (Poynton and Broadley, 1987). In Ethiopia these frogs have...

The systematic affinities of two rare and little-known lamprophiid snakes have been reviewed. One of these species has been long known either as Lamprophis erlangeri or as Boaedon erlangeri. It is endemic to moist montane forest remnants and formerly forested areas in the south and south-west of the Ethiopian highlands. New molecular and morphologi...

Apostolepis albicollaris and A. cerradoensis are two Elapomorphini snake species, described within a short timespan, from the Cerrado of central Brazil. In their brief descriptions, these two species were diagnosed from congeners largely based on highly variable external morphological characters. Interestingly enough, A. cerradoensishas remained kn...

Three species of Phrynomantis Peters, 1867, have been historically recorded for Angola: P. affinis, P. annectens and P. bifasciatus. As noted by all authors who have dealt with specimens of P. bifasciatus from the country, the Angolan population is characterized by an odd coloration pattern for the species, which led Boulenger to consider it a diff...

Erythrolamprus Boie, 1826 is a highly diverse dipsadid snake genus, ranging from Central America south to Argentina and Uruguay. In this work, we reassess the taxonomic status of specimens previously identified as Erythrolamprus poecilogyrus schotti (Schlegel, 1837) from the savannah habitats of Roraima state, northern Brazil, Guyana, and Bolívar s...

A new ground-dwelling species of treefrog in the genus Leptopelis is described from the Harenna Forest in south-eastern Ethiopia. The description is based on morphology and acoustics and is supported by molecular data. The new species has a small body size, and the digital discs on fingers and toes are significantly more conspicuous than in other s...

Phalotris Cope, 1862 is a fossorial dipsadid snake genus that encompasses 15 species, distributed mainly in open areas from Northeastern Brazil to Southern Argentina. Some of its species are known from small series, and there is little to no knowledge on their morphological variation and species delimitations. In this work, we analyze the taxonomic...

Apostolepis is a diverse Dipsadid snake genus, with 35 known species, inhabiting most of South America at east of the Andes. In this study, we redescribe Apostolepis assimilis Reinhardt, 1861, and evaluate the taxonomic status of a controversial taxon, Apostolepis tertulianobeui, described based on a single specimen from an unknown locality of Mina...

Apostolepis Cope, 1862 is a speciose dipsadid snake genus. Among its more than 30 taxa, several species are known only from small series of specimens. The lack of basic information about morphological variations and natural history has resulted in a difficult taxonomic history of the group. We revisit the taxonomic status of the recently described...

Apostolepis is a speciose Neotropical snake genus, encompassing 38 species, widely distributed in South America. Most species of the genus are known based on small series, which has contributed to a convoluted taxonomic history. In this study, we report the rediscovery of Apostolepis niceforoi, a taxon that remained known from a single specimen sin...

Apostolepis Cope, 1862 is a highly diversified and speciose Neotropical dipsadid genus, encompassing almost 40 species of fossorial or cryptozoic snakes, widely distributed east of the Andes. In this work, we revisit the taxonomic status of A. sanctaeritae Werner, 1924, a rather controversial taxon described from a single specimen. Apostolepis sanc...

Phrynobatrachus inexpectatus and P. minutus are sister species of dwarf-size puddle frogs endemic to humid montane forests in the Ethiopian highlands. For almost two decades P. inexpectatus was officially known only from two populations, although a wider distribution was assumed. We confirm a population of this species in Harenna Forest (Bale Zone)...

The tadpole of poorly studied Leptopelis ragazzii (Boulenger, 1896), a high-altitude tree frog species from the Ethiopian highlands, is described for the first time and compared with closely related sympatric species — L. gramineus (Boulenger, 1898) and L. vannutellii (Boulenger, 1898).

Apostolepis is a diverse neotropical snake genus, which has been historically subjected to poor taxonomic descriptions, largely based on either a small type series or subjective diagnoses. We evaluate the case of Apostolepis barrioi Lema, 1978 and its intricate taxonomic history, suggesting its synonymization with Apostolepis dimidiata (Jan, 1862),...

I here report the first record of Pseudoboodon gascae from a forest habitat in southern Harenna Forest, Bale Zone, Oromia, Ethiopia.

During a scientific field expedition to the Alai-Pamir range five specimens of the genus Gloydius have been collected in the larger Alai. A morphological and genetical examination of the specimens has shown that they are part of the G. halys complex, but represent a new taxon which is characterized by the following unique character combination: It...

Technical solutions usually adopted for computer-based language teaching and testing materials were developed for purposes other than language learning. To understand the features offered by this technology and to formulate the requirements for their further development and improvement, the authors of language teaching materials need to know which...

A look from the viewpoint of the linguistic theory of text, as in this article, may result in reconsideration of some key-ideas common to many non-linguistic publications about hypertext. Since hypertext is frequently thought of as a primarily textual phenomenon (single text or system of texts), the authors of this article search for its linguistic...
