GNAMPTOPELTA HOPPER, 1939 View in CoL View at ENA

Gnamptopelta Hopper, 1939: 333 View in CoL . Type-species: Trogus obsidianator Brullé. Original designation.

Species and distribution. There is one species found in North America ( Sime & Wahl 1998).

Autapomorphies. Apical margin of clypeus concave (#4–1); scutellum conical (#20–2); propodeum with median longitudinal carinae anteriad anterior transverse carina present (#32–0); median longitudinal carinae of T1 apically incomplete (#46–1); S2-3 divided, S4-5 entire (#55–1). Alternate combinations: (1) #s 4–1, 20–2, and 55–1, or (2) #s 4–1, 20–2, 32–0, and 55–1.

Biology. G. obsidianator is a larval-pupal parasitoid of Sphingidae ; it has been reared from Amphion floridensis B.P. Clark attacked as third- and fifth-instars ( Sime & Wahl, 1998). The association of male and female G. obsidianator with grapevines ( Heinrich 1962, 1977) suggests that this species specializes on Vitaceae-feeding sphingids (of which there are at least 10 species in its range ( Hodges 1971)), but the degree of specificity is unknown. Reports of G. obsidianator attacking Papilio polyxenes Fabricius (Papilionidae) and Pyrrharctia isabella (J.E. Smith) (Arctiidae) ( Weed, 1888; Howard, 1889; Bischoff, 1915; Hopper, 1939) are not corroborated by voucher specimens or recent records; we consider them implausible.
