Dendrobates sp.   Wagler, 1830

Common Name: a Dart-poison Frog

Taxonomy: available through ITIS logo

Identification: This specimen of the genus Dendrobates has not been identified with any certainty.  In general, dart-poison frogs are small dendrobatids (poison frogs), ranging in length from 15-62 mm (0.6-2.5 in) (Silverstone, 1975; Zweifel, 1998).  The typically beautiful color patterns are highly variable, even within species, and have been illustrated by several authors (Silverstone, 1975; Walls, 1994; Lamar, 1997).  Illustrations of the tadpoles of different species of Dendrobates can be found in Silverstone (1975) and Walls (1994).

Size: snout-vent length of 15-62 mm

Native Range: The genus Dendrobates is indigenous to Central America, and the northern and central portions of South America (Silverstone, 1975; Walls, 1994; Campbell, 1999; Duellman, 1999; Zug et al., 2001).

Nonindigenous Occurrences: In 1994 a single specimen of Dendrobates, not identified to species level, was collected in Honolulu, Oahu, Hawaii, U.S. (Bishop Museum Records—1997 output, Bishop Museum, Honolulu, Hawaii).

Means of Introduction: Unknown; but it is probably a pet release.

Status: If this is a new species to the island of Oahu it is probably not established.

Impact of Introduction: None.  However, should any of these insectivorous frogs establish a population in a state that has no indigenous, and only nonindigenous species of frogs (McKeown, 1996), a further burden would be placed upon the ecology of Hawaii.

Remarks: The taxonomy of Dendrobates and related dendrobatids has been reviewed or summarized by many authorities (Silverstone, 1975; Myers and Daly, 1983; Frost, 1985; Zimmermann and Zimmermann, 1988; Caldwell, 1996; Summers et al., 1999; Zug et al., 2001).  Members of the genus Dendrobates are nonaquatic, mostly tropical, diurnal frogs that primarily have an insectivorous diet (Silverstone, 1975; Walls, 1994; Zweifel, 1998; Pough et al., 2001; Zug et al., 2001).  In many species the skin toxins seem to be derived from their diet; especially ants (myrmecophagy: Caldwell, 1996).  The reproductive behaviors of different species of dart-poison frogs have been the subject of much study due to the complex variety of parental care that one (paternal or maternal) or both parents provide the eggs and tadpoles (Wells, 1981; Weygoldt, 1987; Zimmermann and Zimmermann, 1988; Crump, 1995, 1996; Summers et al., 1999; Zug et al., 2001).

An effort should be made to ensure that the specimen from Honolulu, Oahu, is not an unverified D. auratus; the only Dendrobates that has established populations in Hawaii (Oliver and Shaw, 1953; McKeown, 1996; also see the species accounts titled "Dendrobates auratus (Girard, 1855)" and "Dendrobates leucomelas Steindachner, 1864" on this website).

Species of Dendrobates and other dendrobatids are popular in the commercial pet trade (Zimmerman[n], 1979; Mattison, 1987; Zimmermann, 1986; Walls, 1994; Davies and Davies, 1997).
