Stenotarsus validicornis Gerstaecker (1858:331)

Diagnosis. Length 3.5–4.2 mm; width 2.8–3.5 mm. Body stout, red­orange; antennomeres III­VIII short, antennomeres IX­XI elongated and nearly parallel sided ( Fig. 1 ); pronotal lateral edge with a small tooth at middle; no notable sexual dimorphism.

Remarks. According to Arrow (1920:49) the Panama specimens of Stenotarsus claviger Gerstaecker (1858) discussed by Gorham (1890) are actually S. validicornis . The specimens studied are from several South American countries (FSCA), with one from Panama (PESC).
