Minipteryx gen. nov.

Figs 1–16

Diagnosis. A rather large limoniid tipuloid, the male almost completely black without any distinct markings. Head ( Figs 1 , 8 ) with rostrum almost completely atrophied, palps only 2-segmented and antennae 12-segmented. Thorax ( Figs 2 , 9, 10 ) short and narrow, without V-shaped thoracic suture developed; katepisternum small, all coxae very large, formula of tibial spurs 1/2/1, claws simple, wing greatly reduced in size and halter without distinct knob. Abdominal segments 3–6, but particularly segments 4 and 5 ( Fig. 11 ), with distinct bump on each side just past mid-length. Terminalia ( Figs 4–7 , 12–16 ): segment 9 a simple ring that is apically not produced, lobed or indented; two pairs of gonostyli, the inner simple, the outer armed; aedeagal complex ( Figs 6, 7 , 14, 15 ) strongly sclerotized, the parameres narrow rods, the aedeagus clawshaped, bifid (double-branched), pointing distinctly ventrad (as in Fig. 14 ).

Etymology. The generic name refers to the almost minimal size of the wings.
