We review morphology and systematics of Phoxophrys using new specimens of previously rare species. In addition to external characters, we relied heavily on skull morphology visualized using computed tomography data of all currently recognized species in this genus. Phylogenetic analysis of ND4, 12S, and 16S mDNA sequences reveal that Ph. tuberculat...

... ventral aspect, the tail tapers distally to the end of the retracted hemipenis, then bears a subtle swelling extending about as far as the dorsolateral crests (Fig. 7). This swollen portion of the tail bears enlarged subcaudals in Bornean Phoxophrys. As noted by Inger (1960), Ph. cephalum has two enlarged subcaudals, whereas other Bornean species have four enlarged subcaudals. The scales are poorly differentiated in females of Ph. anolophium, but countable and evident in both sexes of the other ...

... in the six males of Phoxophrys borneensis in the NMW, a wash of greenish to greenish-orange pigment encircles the tail over the section with enlarged subcaudals (Fig. 7). We noted an identical band overlying enlarged subcaudals of Lophocalotes ludekingi in the same collection. We cannot explain the presence of these bands of pigment. They warrant histological study and likely represent an undescribed glandular product or chemical compound deposited in the stratum corneum of this portion of the ...

... sexes of Phoxophrys borneensis have prominent charcoal stripes extending posteriorly and medially across the throat (Fig. 7). In contrast, the holotype and one Dorsal coloration will immediately distinguish adult male Phoxophrys borneensis from male Ph. cephalum. Male Ph. borneensis are very dark green (dark blue in preservative) with narrow yellow bands (white in preservative; 1-2 dorsals long and including enlarged tubercles), whereas male Ph. cephalum are ...

Ophiostoma species, some of which cause sapstain in timber and/or are mild pathogens, are common fungal associates of bark beetles (Coleop�tera: Scolytinae). Three new Ophiostomataceae from Spain are recognized in the present study based on comparisons of sequence data for three gene regions as well as morphological characteristics. The new taxa ar...

... Fixed differences between samples and non-overlapping meristic and mensural characters provide the strongest form of evidence for interrupted gene flow. Nonetheless, as discussed in more detail by Harvey et al. (2020), differences in means can provide additional evidence in support of taxonomic changes. In this study, we compared means or size-adjusted means for 20 meristic and 6 mensural characters. ...
... Finally, G. lacunosus is the only species with a divided rostral scale. Although Harvey et al. (2020) defined this character, some observers may be unsure about whether the rostral is divided. In such cases, a ratio of rostral width to height will almost always be smaller in G. lacunosus than in other members of the group (Table 1). ...

We describe a new species of the Gonocephalus megalepis group and provide new morphological and distribution data for the three other species of the group. The combination of a wide gap between the nuchal and dorsal crests, distinctly heterogenous scales on the flanks, a gular crest, two large tubercular scales ventral to the tympanum, and 97–125 scales around midbody will distinguish the new species from all congeners. The new species occurs above 1100 m on mountains of Sumatra's southern Bukit Barisan Range below 3°S latitude. Head scales of some specimens were infested by a green, filamentous symbiont, which we tentatively identify as an epizoic plant. Gravid females develop crimson stripes on their gular pouch as an apparent social signal.

An inventory of herpetofauna species from western part of Nusa Kambangan Island, Central Java, Indonesia, is presented. There are 43 herpetofauna species reported (16 amphibians and 27 reptiles). This study confirmed new distribution record and list some of threatened species. In light of the imminent human disturbances on Nusa Kambangan Island, a conservation plan is urgently needed.
