Genus Paramydas Carrera & cl' Andretta

Paramydas Carrera & d'Andratta, 1948: 490 . Type-species, Mydas igniticornis Bigot (orig. des.).

Head in anterior view one and one-third times as broad as high; face at antennae one-third width of head; oral margin at one-third distance from lower eye margin to antennae. Proboscis similar to Messia­ Sial labella subequal to length of oral cavity; palpi very small. Antennal segment 1 cylindrical, about as broad as long; 2 one-half length of 1 and slightly wider than long; 3 slender and about three times as long as 1-2; club one and one-fifth times as long as 3 and about one-third as broad as long (Fig. 32).

Mesonotum with short hairs on lateral margins and dorsocentral stripes. Scutellum with short hairs. Postscutellum slightly rugose, bare. Pleura with long hairs on episternum-L, mesopleura (dorsal and posterior margins), pteropleura, katepimeron, and metasternum.

Abdominal tergite-1a rounded, a few hairs below; Ip with sparse, fairly long hairs; remainder with sparse, recumbent hairs; tergites 1, basal one-fourth of 2, and narrow posterior margins of 2-7, smooth; remainder of 2-7 with many deep, large punctures; bullae (Fig. 53) small, about twice as long as wide. Sternites 2-7 with deep numerous punctures, hairs sparse, recumbent, becoming numerous apically; 0 8 rugose and about one-half length of 7, hairs short, dense, semi-erect. Female terminalia with apical hairs, similar to Mydas . Male genitalia (Figs. 119-121): hypandrium coalescent with basistyli, capsule-like, as in Mydas and Messiasia ) hemispherical in outline; apical processes with a beak directed inwards; aedeagus conical, with well-developed lateral apodemes, in the shape of a large wing; epandrial halves triangular, completely separated; cerci separated.

Fore and middle legs slender, fore femora one and one-half times as wide as their tibiae. Hind femora swollen, about five times as long as broad; venter with about 16 tuberculate spines; hairs sparse and re- cumbent, a few short, erect hairs on dorsum. Hind tibiae with ventral keel, apical spur subequal in length to width of hind metatarsus and with small bristle at base. Hind metatarsus about two and one-half times as long as wide and subequal in length to segments 2-3.

Alulae with dense fringe of squamose hairs. Wings about three times as long as broad; second submarginal cell open, nearly closed in a few specimens; posterior crossvein present; axillary lobe as broad as long; ambient vein complete.

Length: 18-23 mm.
