|Distribution||Sierra Leone ?, Nigeria ?|
Type locality: ‘‘Lagos, Sierra Leone’’ (unclear locality: there is no Lagos in Sierra Leone).
|Types||Holotype: ZMH R.K. 1070-E.K. 13179; destroyed.|
|Diagnosis||Description. Rostral moderate, triangular; nasal fused with first and second labials, preocular and prefrontal, forming a long suture with its fellow behind the rostral; no prefrontals; frontal small; a pair of postfrontals; a pair of parietals; no occipitals; no supraocular; no preocular; ocular large, eye distinct; 1 (third) upper labial; 2 temporals, upper very large, forming an extensive suture with a postfrontal and parietal; mental elongate; 2 lower labials, first very large, second small; no postmental; 4 chin shields, all of which are in contact with a first lower labial; 243 annuli on body, 26 on tail; 17 (10 + 7) segments in a midbody annulus, the median ventral segment six times as broad as long; 6 anals; preanal pores.|
Coloration. Above, pale brown; below, white.
Measurements. Total length 120 (107 + 13) mm.
Remarks. Obviously derived from Amphisbaeua leonina of Tumbo Island, French Guinea, from which it differs in having 26 annuli (instead of 20) on tail; in 17 (instead of 24) segments in a midbody annulus, the median ventral segments being 6 (instead of less than 2) times as broad as long; absence (instead of 3-6) of preanal pores ; and of doubtful consequence, no postmental, it having divided longitudinally to form 4 chin shields.
|Comment||Abundance: only known from the type specimen (Meiri et al. 2017).|
|Etymology||Named after Pedro de Grys (de Grijs) who worked at the Zoological Museum, Hamburg, and who lent the specimens to Loveridge.|
