Chimarra (Curgia) conica Flint 1983

Chimarra (Curgia) conica Flint

Chimarra (Curgia) conica Flint, 1983:20.

ADULT.—Length of forewing, and 6–7.5 mm. Color uniformly jet black (examples from Nova Teutonia have a broad, golden band in center of wing).

Male Genitalia: Eighth sternum narrow, slightly widened dorsad; tergum with posteromesal margin produced into a short, broad lobe (eighth segment omitted from Figures 21, 23). Ninth segment produced anteroventrally; tergal area broad; posteroventral keel produced as an elongate, trianguloid process. Cercus elongate, rounded apically. Tenth tergum entire; in lateral aspect with apex enlarged from both dorsal and ventral margins (in the variety this enlargement is grossly exaggerated, Figure 22); in dorsal aspect tapering to a narrowly rounded tip; apically with many sensillae arranged around apex; ventrolateral process with a short, posteroventral extension. Clasper elongate, concave dorsally, tapering apicad; in ventral aspect with inner margin straight, rounded laterally, produced into an apicomesal point. Phallus tubular, with apicodorsal surface produced; internally with a small, basal, rod-and-ring assembly and 15 to 20 short, black spines.

ETYMOLOGY.—From the Latin conus, in allusion to the shape of the tenth tergum in dorsal aspect.

Chimarra (Curgia) conica

This species is clearly related to C. moselyi Ross and is undoubtedly the species recorded from Misiones, Argentina, by Ulmer (1913) as C. morio Burmeister. This and C. plaumanni are closely related, with the shape of the claspers offering the most distinctive differences. In C. conica the claspers are longer, narrower (in lateral aspect), concave upwardly, and taper to an apical point in ventral aspect.

ADULT.—Length of forewing, 6–7.5 mm. Color jet black in entirety. Forewing without bulla in radial system; hind wing with 4 branches to Rs, a closed discal cell, and 3 branches to M.

Male Genitalia: Eighth sternum narrowed ventrally; tergum slightly produced posteriad middorsally. Ninth segment enlarged anteroventrally; posterolateral margin with a small lobe; posteroventral keel pointed apically. Cercus enlarged and rounded apically. Tenth tergum hoodlike, enlarged apicad in lateral aspect, in dorsal aspect evenly tapering to an acute posteromesal point; venter laterally produced into a long, slender ventral process, the apex of which is angled posteriad above clasper. Clasper elongate, concave dorsally, tapering to a pointed apex in ventral aspect. Aedeagus with apicodorsal surface strongly sclerotized; internally with a small, broad, rod and ring assembly, and 15–20 small, black spines.
