DistributionGuadeloupe, Marie-Galante; Virgin Gorda (Barbour 1917)

Type locality: Guadeloupe.  
Reproductionoviparous 
TypesSyntypes: MNHN 3547-3548.
Syntypes: MNHN-RA 3555 and 3556 (Variety A); MNHN 3554, 3558 and 1994.0761 (Variety B) [Dromicus leucomelas] 
DiagnosisDiagnosis (genus): Species in this genus have 19–23 midbody scale rows, 184–220 ventrals, 94–138 subcaudals, two apical scale pits, eight upper labials, 10 lower labials, 18–21 maxillary teeth, and 21–26 dentary teeth (Table 2). Alsophis differs in at least one of these characters from all alsophiine genera except Borikenophis and Hypsirhynchus. Alsophis differs almost completely from Hypsirhynchus in ventrals (184–220 versus 123–189 in Hypsirhynchus). It differs from most Borikenophis (163–187), except for B. sanctaecrucis (191–198), in having a higher number of ventrals (184–220).

Diagnosis (genus): Hemipenes bicalyculate; enlarged intrasul‐ cal spines present on each side of the sulcal region; lobular crotch and medial surfaces of the lobes almost completely nude; capitular overhanging edge com‐ posed of a thin fringe of tissue (fide ZAHER et al. 2009). Note that Zaher’s diagnosis also included Borikenophis sanctaecrucis. 
CommentSynonymy: The co-types of Psammophis antillensis SCHLEGEL 1837 represented 3 species; Brongersma 1937 selected the Guadeloupe specimen as lectotype.
Alsophis antillensis sanctonum and Alsophis antillensis danforthi have been elevated to species status and re-assigned, respectively. See entry for A. sanctonum.

Type species: Psammophis antillensis SCHLEGEL 1837 is the type species of the genus Alsophis FITZINGER 1843.
