Family Colubridae

The family Colubridae, which includes the kingsnakes (Lampropeltis spp. ), is the largest, most widespread, and diverse family of snakes , with few physical characteristics universal among all species. The family contains 70 percent of the known species of snakes, with more than 1700 species worldwide (Pough et al. 1998). Although some colubrids are dangerously venomous , most are harmless to humans. [1]

Notes

Name Status: Accepted Name .

Comment: holotype: USNM 198530 (male, equatoriana) Tantilla melanocephala capistrata has been elevated to species status. Tantilla equatoriana has been synonymized with T. melanocephala by GREENBAUM et al. (2004). T. ruficeps has been resurrected from the synonymy of T. melanocephala by SAVAGE (2002). Tantilla equatoriana was described from 2 male specimens of undetermined maturity from San Lorenzo, Esmeraldas Province , Ecuador (Wilson and Mena, 1980). This taxon was distinguished from all congeners by several characters: 1) a dark head cap grading into a dark nape band with 2 pale spots that cover the posterior part of the parietals , the posterior part of the posterior temporals, and associated postparietal scales ; 2) a pale preocular ''spot'' that contacts the preocular scale and eye; 3) a postocular ''spot'' that contacts the lateral gulars without interruption by a lateral extension of the head cap; 4) the absence of a pale neck band posterior to the dark nape band; 5) a tan background color with 9 dark brown stripes (in the middle of Scale Row 1, extending from the upper half of Row 2 to the lower half of Row 3, the top of Row 4 to the bottom of Row 5, the middle of Row 6 and the middle of the vertebral Scale Row 8); and 6) a greater number of subcaudals (77 to 79) in comparison with other members of the T. melanocephala Group (Wilson and Mena, 1980; Wilson, 1988). The T. melanocephala Group is the second largest species group in the genus and includes T. andinista, T. capistrata, [T. equatoriana,] T. insulamontana, T. lempira, T. melanocephala, and T. miyatai (Wilson, 1999). This species is characterized by extensive geographic variation in color pattern , ventral and subcaudal counts, and habitats occupied (Wilson and Mena, 1980). Not listed in LINER 1994.
