Stenotarsus subtilis Arrow (1920:53)

Stenotarsus rotundus Arrow , of authors: Denlinger 1986, 1994, 1996; Nedved 1996; Nedved and Windsor 1994 a, b; Tanaka 1986; Tanaka, Denlinger, and Wolda 1987; Tanaka, Wolda, and Denlinger 1987 a, b, 1988; Wolda and Denlinger 1984; Yoder, Denlinger, and Wolda 1992.

Stenotarsus ‘‘ gigante ’’ (Nedved 1996:3) Nomen Nudum

Diagnosis. Length 4.5–6.0 mm; width 3.5–4.2 mm. Body oval, elytra lacking distinct coarse punctures near humerus ( Fig. 6 ), smoothly and evenly punctate; male with spine on metatrochanter, lacking depression on anterior margin of metasternum ( Fig. 14 ), genitalia relatively short and broad ( Fig. 18 ). Females also recognizable by elytral punctation.

Remarks. Nedved’s (1996) use of the name S. ‘‘ gigante ’’ is not accompanied by a description nor any comments to set the identity of that population. Since we consider the Gigante population to be conspecific with S. subtilis , S. ‘‘ gigante ’’ is listed as a nomen nudum and placed as a synomym of S. subtilis .

Specimens studied include three female syntypes of S. subtilis (NHML) from David (near sea level) and V . [Volcan] de Chiriquı´, Panama (approximately 1,200 m above sea level), as well as numerous specimens from both the Barro Colorado Island and Gigante Peninsula populations (approximately 100 m above sea level). Specimens from the aggregations collected during 1993–1999 will be deposited in various museums ( STRI, NHML, FSCA, PESC, NMNH, OSUC, FEUP) .
