Diagnosis | Diagnosis. 1) Ground color of body bronze, a black postocular stripe extending onto the neck only; 2) pale and dark ventrolateral stripe absent; 3) relatively indistinct transverse bands on anterior part of lateral body; 4) loreal single; 5) vertebral scales strongly enlarged; 6) dorsal scale rows 15-15-11, all smooth; 7) ventrals 193–197, subcaudals 130–135, paired; 8) SVL/TOL ratio 0.292–0.301; 9) supralabials 9, 4th through 6th touching the eye; 10) the outermost row of dorsal scales the same color as other dorsal scales; 11) retracted hemipenis extending to the 6–7th subcaudal scales. Comparison. Dendrelaphis vogeli sp. nov. differs from D. biloreatus, D. calligaster (Günther), D. caudolineatus (Gray), D. caudolineolatus (Günther), D. flavescens (Gaulke), D. fuliginosus Griffin, D. gastrostictus (Boulenger), D. keiensis (Mertens), D. levitoni (van Rooijen & Vogel), D. lineolatus (Jacquinot & Guichenot), D. lorentzii (Lidth de Jeude), D. luzonensis Leviton, D. macrops (Günther), D. modestus Boulenger, D. papuensis (Boulenger), D. philippinensis (Günther), D. punctulatus (Gray), D. sinharajensis Wickramasinghe, D. striolatus (Peters), D. terrificus (Peters) and D. walli Vogel & van Rooijen by having 15 dorsal scale rows at mid-body (vs. 13 dorsal scale rows at mid-body). Dendrelaphis vogeli sp. nov. differs from D. ashoki (Vogel & van Rooijen), D. bifrenalis (Boulenger), D. chairecacos (Boie), D. grismeri Vogel & van Rooijen, D. haasi van Rooijen & Vogel, D. hollinrakei, D. marenae Vogel & van Rooijen, D. oliveri (Taylor), D. pictus, D. schokari (Kuhl) and D. tristis (Daudin) by lacking the pale ventrolateral stripe (vs. present). For having 193–197 ventrals and 130–135 paired subcaudals, Dendrelaphis vogeli sp. nov. differs from D. for- mosus (Boie) (vs. 172–194 VEN, 142–162 paired SC), D. girii Vogel & van Rooijen (vs. 167–173 VEN, 140–147 paired SC), D. grandoculis (Boulenger) (vs. 174–176 VEN, 117 paired SC), D. kopsteini Vogel & van Rooijen (vs. 167–181 VEN, 140–151 paired SC), and D. subocularis (vs. 151–174 VEN, 91–109 paired SC). Dendrelaphis vogeli sp. nov. differs from D. inornatus Boulenger by having one loreal (vs. absent); differs from D. nigroserratus Vogel, van Rooijen & Hauser by having fewer subcaudals (vs. 130–135 paired SC vs. 148–152 paired SC), and lacking a pronounced black saw-tooth pattern on neck (vs. present); differs from D. striatus (Cohn) by having more ventrals (193–197 VEN vs. 149–167 VEN), and coloration of the neck not yellow (vs. neck yel- low when inflated); differs from D. underwoodi van Rooijen & Vogel by having more ventrals (193–197 VEN vs. 183–189 VEN), and lacking a narrow black stripe on posterior body (vs. present); differs from D. andamanensis (Anderson) by lacking the bright grass-green coloration on dorsum (vs. present), and black stripe across the whole temporal region (vs. across only the lower part of temporal region). Dendrelaphis vogeli sp. nov. is most similar to the D. cyanochloris complex, but it differs from D. cyanochloris by having a shorter hemipenis (retracted hemipenis extending to the 6–7th SC vs. 11–18th SC); fewer subcaudals (130–135 vs. 134–157 in D. cyanochloris); indistinct transverse bars on anterior part of lateral body (vs. distinct black transverse bars on anterior part of lateral body); the outermost row of dorsal scale the same color as other dorsal scales (vs. color of outermost row distinctly lighter than others) (Fig. 9). D. vogeli sp. nov. differs from D. ngansonensis by having a shorter hemipenis (retracted hemipenis extending to the 6–7th SC vs. 18th SC); indistinct transverse bars on anterior part of lateral body (vs. distinct black transverse bars on anterior part of lateral body); the outermost row of dorsal scale the same color as other dorsal scales (vs. color of outermost row distinctly lighter than others), fewer maxillary teeth (20–21 vs. 24–25), more distinct blue pattern on forebody (vs. visible only when neck is inflated). |
Comment | |
Etymology | The specific epithet “vogeli” is named after Mr. Gernot Vogel (Heidelberg, Germany), for his excellent contributions to the taxonomy of the genus Dendrelaphis. He and his collaborators published a series of articles to resolve taxonomic problems in this genus and described several new species. |
