Distribution | Puerto Rico (incl. Culebrita), British Virgin Islands (e.g. Anegada) portoricensis: widely distributed in Puerto Rico (including Cayo Santiago) except southern third of island and extreme west. anegadae: British Virgin Is. aphantus: Isla Vieques. nicholsi: Buck Island of the Capella Islands off south coast of St. Thomas, U. S. Virgin Is. richardi: Isla Culebra, St. Thomas and its satellites, Lovango Cay, Peter I., SaltI. Type locality: Puerto Rico. |
Reproduction | oviparous |
Types | Syntypes: ZMUC 60460 (Presumably) = UZM (but missing); other syntype formerly in NMW. Holotype: MCZ 12083 [anegadae] Holotype: BMNH RR1964.944 [aphantus] Holotype: UMMZ 80648 [nicholsi] Holotype: USNM 66522, paratypes: USNM [richardi] |
Diagnosis | Diagnosis (genus): Species in this genus have 17–19 midbody scale rows, 163–198 ventrals, 106–145 subcaudals, 1–3 apical scale pits, eight upper labials, 10 lower labial, 16-21 maxillary teeth, and 22-35 dentary teeth (Table 2). Borikenophis differs in at least one of these characters from all other alsophiine genera except Alsophis and Hypsirhynchus. Except for B. sanctaecrucis (191–198 ventrals), it differs from most Alsophis in having a lower number of ventrals (163–187 versus 184–220 in Alsophis). Most Hypsirhynchus have 19 midbody scales rows (H. ater and H. melanichnus have 17 rows) whereas most Borikenophis have 17 rows (those populations from the Virgin Islands usually have 19 rows).

Distribution: populations from Isla Mona and Isla Desecheo are now B. variegatus. Alsophis portoricensis variegatus SCHMIDT, 1926 has been elevated to full species status by HEDGES et al. 2009. Type species: Alsophis portoricensis REINHARDT and LÜTKEN 1862 is the type species of the genus Borikenophis HEDGES & VIDAL 2009. |
Etymology | Named after its distribution on Puerto Rico. The genus name refers to its distribution centered on the Puerto Rican Bank; Boriken is the Taino word for Puerto Rico. |
