}}Storeria dekayi, commonly known as the brown snake or De Kay's snake, is a small species of snake in the family Colubridae.[2][3]

Geographic range

Storeria dekayi is native to Southern Ontario and Quebec, most of the eastern half of the United States, through Mexico, Guatemala, Honduras, and possibly El Salvador.[1][4]

Description

Dorsally, Storeria dekayi is brown to gray with a lighter center stripe bordered by small black spots; ventrally, it is lighter brown or pink with small black dots at the ends of the ventral scales.[5] Adults usually measure less than {{convert|12|in|cm}} in total length (including tail), but the record total length is {{convert|19+3/8|in|cm}}.[6] It has keeled dorsal scales, and no loreal scale.[7]

Reproduction

Like other natricine snakes (such as watersnakes, genus Nerodia; and gartersnakes, genus Thamnophis), Storeria dekayi is an ovoviviparous species.

Diet

Storeria dekayi primarily feeds on slugs, snails, and earthworms.[8][9] Reports of other invertebrates (e.g., sow bugs, mites, millipedes) in the diet of S. dekayi are most likely the result of accidental ingestion.[10] For example, during predation, invertebrates may adhere to a slug being consumed by a snake.

Etymology

The specific name, dekayi, is in honor of American zoologist James Ellsworth De Kay (1792–1851), who collected the first specimen in Long Island, New York, while the generic name, Storeria, honors zoologist David Humphreys Storer.[11][12]

This is the only North American snake whose binomial is a double honorific – that is, both the generic name and the specific name honor people.

The subspecific name, wrightorum (Latin, genitive, plural), is in honor of American herpetologists Albert Hazen Wright and Anna Allen Wright, husband and wife.[12]

Subspecies

There are seven recognized subspecies of S. dekayi, including the nominotypical subspecies.[4][13]

  • Storeria dekayi anomala Dugès, 1888
  • Storeria dekayi dekayi (Holbrook, 1836) – northern brown snake
  • Storeria dekayi limnetes Anderson, 1961 – marsh brown snake
  • Storeria dekayi temporalineata Trapido, 1944
  • Storeria dekayi texana Trapido, 1944 – Texas brown snake
  • Storeria dekayi tropica Cope, 1885
  • Storeria dekayi wrightorum Trapido, 1944 – midland brown snake

A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Storeria.
