Cirrothaumatia vesta (Clarke, 1968)

(Figs. 9, 13, 18)

Type-locality: Rancho Grande (1100 m), Aragua, Venezuela .

Diagnosis. Wing expanse: 11.8‒13.0 mm (n = 3). This species is very similar to C. pichita n. sp. but the female genitalia (Fig. 9) have the ductus bursae expanded somewhat caudally, thus the caudal end is more funnel-like than stentor-like, and the ductus bursae is longer and narrower (ca. 1.3x longer).

Materials examined. Holotype. Male, Rancho Grande (1100 m), Aragua, Venezuela, 16–23 Oct 1966, S. S. & W. D. Duckworth (gen. slide JFGC-11638) (USNM type 69755) . Paratype. Female, same data as male (gen. slide JFGC-11639) (USNM). Additional specimen examined (n = 1). Venezuela: Rancho Grande (1100 m), Aragua, 25‒26 Jan 1978 (1 male), J. B. Heppner (USNM) .

Biology. Unknown.

Distribution. Known only from northern montane Edo. Aragua, Venezuela, at the Rancho Grande station (1100 m), just north of Maracay in coastal mountains that are the final but disjunct far northeastern remnant of the Andes Range of South America.

Discussion. This is one of only two species in which the male is known, with genital features (Fig. 9a) similar to those of C. tornosema (Fig. 7a). The female genitalia (Fig. 9) also have the main characters of Cirrothaumatia: presence of accessory bursa, adjacent tuba seminalis, simple ostium funnel, and carina-like signum from bursa and along side of ductus bursa similar to those of C. tornosema, but the ductus bursae is considerably more elongated in C. vesta (as in C. pichita n. sp. and C. huemboana n. sp. from Peru).
