Types | Type: Unlocated (McDiarmid et al. 1999) Holotype: unknown; was "Angela" a live specimen in the Terrariode Valencia, Venezuela [hutmanni] Holotype: AMNH 59489 [venezuelensis] [rozei] |
Diagnosis | DIAGNOSIS (venezuelensis = rozei): This subspecies difers from the nominate subspecies, known from Colombia and Central America, in having a lower ventral count, 142-144, as compared to 147-159 for B. 1. lansbergii, and in having the dark dorsal blotches much wider than the light interspaces. Moreover, venezuelensis has a maximum of 25 dorsal rows; there are from 27 to 32 subcaudals; normally there are nine (exceptionally eight or 10) supralabials, 10 or 11 infralabials, and 20 to 23 dark dorsal blotches (Roze 1959). |
Comment | Venomous! Illustration: See color plate 83 in VILLA et al. 1988. Subspecies: Porthidium lansbergii arcosae SCHÄTTI & KRAMER 1993 has been elevated to full species status. Distribution: has also been reported from N Venezuela (Bolívar [HR 34: 389], Zulia) but before arcosae was split off. Synonymy after PETERS & OREJAS-MIRANDA 1970. Porthidium lansbergii annectens (SCHMIDT 1936) is a synonym of P. ophryomegas. Thanatos patoquilla POSADO ARANGO (1889) might be a synonym of P. lansbergii but has been considered as of unclear status by several authors (see MCDIARMID et al. 1999 for a discussion). Previous records of P. lansbergii from W Panama to be based on individuals of Porthidium volcanicum. Similar species: Porthidium volcanicum Note that SANDNER-MOTILLA (1989) dedicated B. l. hutmanni to Adolfo Houtmann (also spelled Hautmann in the paper), but used the name “hutmanni” multiple times including the title. Habitat: terrestrial |
Etymology | Named after Reinhart Frans van Lansberge (1804-1873), a Dutch administrator in the West Indies. |
