Type locality: Madagascar
macrocercus: Madagascar (elevation up to more than 2000 m). Type locality: Eastern Betsileo
|Types||Holotype: BMNH 19184.108.40.206 (formerly 220.127.116.11), purchased E. Higgins.|
Lectotype: BMNH 1918.104.22.168, collected by Rev. W.D. Cowan. Designation by Brygoo (1984) [macrocercus]
|Diagnosis||Description: “All the head-shields exactly as in G. ocellatus, with the exception of one additional supraorbital. Lower eyelid scaly, not transparent; ear large. Scales ev everywhere rounded, smooth, smaller on the sides; in 32 longitudinal series; 70 transverse series between the mentals and the vent. Limbs short, the fore limb, when laid forward, reaching to the anterior margin of the ear: a postaxillary groove not well developed; toes as in G. ocellatus.” (O’Shaughnessy 1879).|
Coloration: “Uniform brown above. Sides densely variegated with blackish, passing into series of dots on all the scales of the ventral surface, the ground-colour of which is whitish; chin blotched; infralabials bordered with blackish.” (O’Shaughnessy 1879)
Further details: Comparison of three specimens with the holotype (BMNH 1922.214.171.124) from `Madagascar' indicates that they are very similar, differing primarily in their larger size (SVL = 97±104 mm vs 78 mm, respectively) and for MRSN R1705.1-2, in their generally darker colour. The holotype and these three specimens share three distinctive features: a diffuse distribution of the dark brown colour on the flanks, a slightly squarish body in cross section and a dark parietal peritoneum. In most other Amphiglossus the pattern is much more uniform and the body is rounded (also squarish in A. splendidus) (Andreone & Greer 2002).
|Comment||Synonymy: Amphiglossus (Brachyseps) gastrostictus is probably a synonym of Brachyseps macrocercus (Erens et al. 2016, electronic supplement). The genus Mesomycterus COPE 1892 is a synonym of Brachyseps, but since the former has not been used in the literature it qualifies as nomen oblitum.|
Type species: Gongylus macrocercus GÜNTHER 1882: 263 is the type species of the genus Brachyseps ERENS et al. 2017.
