Tantilla hobartsmithi

provided by wikipedia EN

Tantilla hobartsmithi, commonly known as the southwestern blackhead snake, Smith's blackhead snake, or Smith's black-headed snake, is a species of small colubrid snake native to the southwestern United States and northern Mexico.

Etymology

The specific name or epithet, hobartsmithi, is in honor of American zoologist and herpetologist Hobart M. Smith (1912–2013).[3]

Taxonomy and systematics

T. hobartsmithi was first described by Edward Harrison Taylor in 1936.

Description

The southwestern blackhead snake is a small snake, growing to a maximum total length (including tail) of 15 in (38 cm), but typically averaging around 8 in (20 cm) in total length.

Dorsally, it is uniformly brown in color, except for the black-colored head, which gives it its common name, and a cream-colored or white collar. On the belly, there is a broad reddish stripe, which runs down the center of the ventral scales.[4]

Venom

T. hobartsmithi is rear-fanged, having enlarged rear teeth and a modified saliva, which while harmless to mammals, is believed to be toxic to arthropods, its primary prey.

Behavior

Blackhead snakes (genus Tantilla) are primarily nocturnal and fossorial, spending most of their time hiding in loose soil, leaf litter, or under ground debris.

Diet

Blackhead snakes eat most varieties of soft-bodied insects and centipedes.

Reproduction

T. hobartsmithi is oviparous.[5]

Geographic range

The southwestern blackhead snake is found in the southwestern United States, in Arizona, California, Colorado, Nevada, New Mexico, Texas, and Utah, as well as in northern Mexico, in Chihuahua, and Coahuila, and Sonora.[6]

Habitat

The preferred natural habitats of T. hobartsmithi are desert, grassland, shrubland, and forest.[1]

Systematyka

Węże tego gatunku zaliczają się do rodziny połozowatych[2], do której zaliczano je od dawna. Starsze źródła również umieszczają Tantilla w tej samej rodzinie Colubridae, choć używają polskiej nazwy wężowate czy też węże właściwe, zaliczanej do infrapodrzędu Caenophidia, czyli węży wyższych. W obrębie rodziny rodzaj Tantilla wchodzi w skład podrodziny Colubrinae[3].
