The western black-headed snake (Tantilla planiceps), also known as the California black-headed snake,[2] is a snake species endemic to the Californias (the U.S. State of California and the Baja California Peninsula in Mexico), as north as the San Francisco Bay and as far east as western Utah, and Texas. [3][4][5] It lives in mostly moist pockets in mostly arid or semiarid environments and spends much of its life underground. It has a flattened head as most crevice-dwellers and is seven to fifteen inches in size. It is brown, slender, olive-gray, with a black head bordered by a white collar. Its habitat is often in woodland, desert areas, grassland and along arroyos in areas that are wet in a usually dry region.[6][7][8]
The western black-headed snake is a member of a larger natural group of small New World terrestrial colubrids, where some of the related species include sand snake (Chilomeniscus), shovel-nosed snake (Chionactis), and the ground snake (Sonora). The western black-headed snake is the sister species of Tantilla yaquia of southern Arizona.[9][10] They are also related to Tantilla gracilis, Tantilla atriceps, Tantilla hobartsmithi and Tantilla nigriceps, all species endemic to the southwestern United States. It is visually similar to the southwestern black-headed snake (T. hobartsmithi).[11] Although they usually appear singly or in pairs, as many as six individual snakes have been observed together. They prey on arthropods, particularly centipedes and beetle larvae, as well as spiders, insects, slugs, and earthworms. They are highly secretive and rarely seen, spending much time under objects, especially during daytime.[12][13][14]

Tantilla planiceps – gatunek węża z rodziny połozowatych.
Taksonomowie wprowadzili pewne zmiany w klasyfikacji: zmniejszyli zakres nazwy T, palniceps, wyjmując z niej uprzednio zaliczane do tego gatunku Tantilla hobartsmithi, Tantilla atriceps i Tantilla yaquia. Z kolei włączono doń Tantilla eiseni, nie zgadzając się na przyznanie tej ostatniej rangi osobnego gatunku[2].
Lepidozaury te zaliczane są do rodziny połozowatych[2], do której zaliczano je od dawna. Starsze źródła również umieszczają Tantilla w tej samej rodzinie Colubridae. Używają jednak dawniejszej polskojęzycznej nazwy wężowate czy też węże właściwe, poza tym Colubridae zaliczają do infrapodrzędu Caenophidia, czyli węży wyższych. W obrębie rodziny rodzaj Tantilla należy do podrodziny Colubrinae[3].
Tantilla planiceps zasiedla Kalifornię w Stanach Zjednoczonych Ameryki oraz Meksyk[2].
Habitaty, w których bytuje, obejmują tereny trawiaste, porośnięte krzakami tereny nadmorskie, cierniste krzewy, chaparral, lasy sosnowo-dębowe, skraje pustyń, tereny kamieniste[2].
Liczebność węża nie została dokładnie oszacowana. Przekracza on 10000, a być może i 100000, utrzymując się na stabilnym poziomie[2].
