Type locality: Niangara, Democratic Republic of the Congo
|Types||Holotype: AMNH 12080, a 652 mm male (H. Lang and J. P. Chapin, Nov. 1910).|
|Diagnosis||Diagnosis: Habitus very slender, tail one-third the total length; ventral plates distinctly keeled; anal entire; three labials entering the eye; one anterior temporal; dorsal scales in fifteen rows; ventrals 164-170, subcaudals, 123 (Schmidt 1923).|
Chlorophis bequaerti is distinguished from C. carinatus by the fifteen dorsal scales and the single anterior temporal. From C. heterodermus, its closest ally, it is distinguishable by the single anterior temporal, the longer tail and higher number of subcaudals, and by a higher number of ventral plates (Schmidt 1923).
Description: Habitus slender, slight compressed, tail length .33 of the t,ot,al,eye large, canthus rostralis distinct. Rostral slightly wider than high, visible from above. Internasals considerably smaller than the prefrontals. Frontal bell-shaped, longer than its distance from the end of the snout, shorter than the parietals. Nasal divided, in contact with the first and second labials. Loreal rectangular, tmice as long as high. A single preocular barely in contact with the frontal; two postoculars. Temporals, 1-1. Nine upper labials, fourth, fifth and sixth entering the eye. Eleven lower labials, first.five in contact wit,h the anterior chin shields. Posterior chin shields longer, with a long median suture. Dorsal scales, 15-15-11, very oblique anteriorly. Ventral plates 164, with a distinct keel. Subcaudals, 123. Total length 652 mm., tail 212 mm. (.33) (Schmidt 1923).
Coloration: dark bluish gray above and below. Posterior chin shields and gulars light (Schmidt 1923).
|Comment||Has been confused with P. angolensis by Rasmussen (1991) and is probably absent from the Congo (but present in the Democratic Republic of the Congo!).|
Habitat: fully arboreal (Harrington et al. 2018).
|Etymology||Named after Dr. Joseph Charles Bequaert (1886-1982), a Belgian botanist, entomologist, and malacologist who graduated with a doctorate in botany from the University of Ghent (1906). He later worked for the colonial government in the Belgian Congo (1910-1915). He moved to the USA (1916), becoming a U.S. citizen (1921). He was a Research Assistant, American Museum of Natural History (1917-1922), then worked at Harvard (1923-1956), initially teaching entomology at Harvard Medical School and finally becoming Professor of Zoology, Museum of Comparative Zoology.
