A. frirhstorferi Werner, 1904 is synonymous with A. lepidogaster Cuvier, 1829. Calotes brevipes is placed in the genus P,serrdocrrlotes. A taxonomic synopsis is presented. A key to the agamid genera Acarithosatrra, Bronchocelu, Ciilotes, Pseirrlocrrlotc~,s and Dendragarizn is given.

It is rare in Bali and Borneo. The juveniles are often confused with its morphologically similar congener, B. cristatella, which occurs widely throughout the Indonesian Archipelago and Peninsular Malaysia. We examined the morphology of B. jubata based on museum specimens including its two available syntypes, and redescribed the species based on the lectotype designated herein. We highlight the characters of B. jubata with a morphometric comparison to its sympatric congener B. cristatella from Java Island, Indonesia. Based on the current distribution pattern and the apparent threats, we update the conservation status of B. jubata using IUCN Red List Criteria, and propose that it be considered as a species of Least Concern (LC), endemic to the Greater Sundaic Islands.

We redescribe the type and compare it to the other four currently recognized East African Tomopterna species. However, based on usual morphological criteria, right now it can not be decided whether T. monticola is a separate, valid species or a senior (T. luganga) or junior synonym (T. tuberculosa) of another name.

Oligodon waandersi sensu stricto is widely distributed (up to 1200 m above sea level) throughout the southern, some parts of the central, and the northern slopes of Central Sulawesi Island, Indonesia, whereas a similar species, O. propinquus, is only known from its holotype and considered to have originated from Java. Here, we demonstrate that O. propinquus is a close match with the northern population (North and Gorontalo) of O. waandersi and morphologically distinct; hence, we consider the type locality of O. propinquus as North Sulawesi, not Java. Oligodon taeniurus, long considered a junior synonym of O. waandersi, is a distinct species, but here we synonymize it with the morphologically closely matched O. propinquus, which has priority over O. taeniurus. Oligodon waandersi in Southeast Sulawesi (including some populations of Buton Islet) is morphologically distinct from O. waandersi sensu stricto in South Sulawesi; hence, it requires a new name. The new species is distinguished from congeners by having the following combination of characters: maximum snout–vent length of 340 mm, a single postocular, a single cloacal plate, a completely divided nasal, ventrals 150–169, subcaudals 18–26, temporals 1+2, six supralabials with third and fourth in contact with eye, dorsal scale rows 15-15-15, hemipenes not forked and covered with spines, maxillary teeth 6–7, shorter tail (6.8–11.2% of total length), brownish dorsum with few dark-edged spots on the vertebral line anteriorly, reddish brown vertebral line on the posterior body and tail, mostly a blackish brown blotch below the eye, and whitish collar band interrupted middorsally. We provide a complete redescription for O. waandersi and O. propinquus based on respective holotypes deposited at the Natural History Museum London and the Zoologisches Museum Hamburg.

For each species of the genus a taxonomic synopsis, diagnosis and distribution, based on voucher specimens and new specimen records, is given. A neotype for Bronchocela hayeki is designated. A new smaragdina -like species from the Central highlands of Vietnam is described by Hallermann and Orlov. Special attention is drawn to the dispersal and colonization scenario of the Philippine Islands by B. cristatella and B. marmorata including exact distribution patterns for both species. A subspecific subdivision of B. marmorata can no longer be perpetuated on morphological grounds. Lophyrus spinosus Dumeril, 1851, regarded as B. marmorata , is in fact a Gonocephalus sophiae (Gray, 1845). A determination key to all species of Bronchocela based on external morphological characters is given.

Historically, these island populations have been referred to as part of either the Boaedon fuliginosus species complex or Boaedon capensis species complex, two of the most taxonomically challenging groups of African snakes, or considered a distinct taxonomic entity, B. bedriagae. Here we review the São Tomé and Príncipe populations through a combination of morphological and molecular data. Our results suggest that each island population represents a unique species. After a thorough review of the taxonomic and nomenclatural history of the group, we revalidate B. bedriagae, restricting the application of this name to the São Tomé population by the designation of a lectotype. We also describe the Príncipe population as a new species, Boaedon mendesi sp. nov. This description has implications to our understanding of the diversity and phylogeographic patterns of the Gulf of Guinea Oceanic Islands.

The ethmoidal region of D. taylori is characterized by a short nasal vestibule, a well developed concha, a much reduced and nearly functionless Jacobson's organ, an incomplete nasal roof, and a true nasopharyngeal duct with a complicated secondary palate. Cartilaginous and epithelial structures of the ethmoidal region provide many informative and useful characters for a phylogenetic analysis. Different anatomical features of D. taylori are compared with other burrowing forms (Acontias mekugk, Anniella, pulchra Lhettzkowia mira, Fqlinia cumn) and discussed functionally and phylogenetically. Phylogenetic analysis of all higher squamate taxa using 144 available data derived from many regions of the body indicates relative relationships as (((Dibamidae, Amphisbaenia) Serpentes) Scleroglossa).

The name-bearing type of Lophyrus spinosus is the specimen collected by Hombron and Jacquinot (MNHN 6896) by original designation and the holotype by monotypy of Bronchocela marmorata is the specimen deposited under NHMUK 1946.8.11.16. Accordingly, these two scientific names do not share name-bearing types. Prior to the original descriptions of Lophyrus spinosus and Bronchocela marmorata Hombron & Jacquinot (1843) published a plate depicting Lophyrus spinosus, but only naming the species in French. The nomenclatural implications of this publication are discussed. Our comparison of the holotypes reveals that these two species are not identical. Therefore we resurrect Lophyrus spinosus from its synonymy with Bronchocela marmorata and show that the specimen collected by Hombron and Jacquinot actually belongs to the genus Hypsilurus. Duméril and Duméril (1851) were the first to make the name Lophyrus (= Hypsilurus) spinosus available and the authorship has to be assigned to them. Based on evidence from original travel reports and biogeography we propose that the collection locality of Lophyrus spinosus, i.e. Hypsilurus spinosus Duméril & Duméril (1851), should be corrected to Triton Bay, Kaimana,

The taxonomic status of the African species Mehelya baumanni, M. riggenbachi and M. rostralis, described by Sternfeld in 1908 and 1910, is discussed in more detail. The unique type specimen of Simocephalus baumanni is identified as Mehelya guirali, S. riggenbachi as M. crossi and S. rostralis as M. stenophthalmus. It is also confirmed that Boodon infernalis (Günther, 1858) is a junior synonym of Lamprophis inornatus (Duméril, Bibron &amp; Duméril, 1854) contributing to the problematic species discrimination in this specious and widespread African genus.

The holotype of the new species was formerly regarded as a syntype of P. oweri. A review of all species of the genus is given including a differential diagnosis and a key to the species. Diagnostic characters for the genera Bronchocela, Calotes, Dendragama were established. Paracalotes poilani and Pseudocophotis sumatrana, showing all diagnostic characters of the genus Pseudocalotes, are included in that genus. Members of Pseudocalotes of the Indochinese region can be differentiated from members inhabiting the Sunda region by the shape of the scales under the third toe. c
