Smicridea (Smicridea) penai Flint & Denning 1989

Smicridea (Smicridea) penai

This species, closely related to pucara and less so to manzanara, is recognized with certainty only by structures of the male phallus. In penai, the lateral plates are sharply upturned at the apex and more elongate with a larger mesobasal shoulder in ventral aspect. The females clasper receptacle is large and rounded in lateral aspect in this species, while the vaginal sclerites are distinctly formed and strongly sclerotized mesally.

ADULT.—Length of forewing, 9–11 mm. Color brown, appendages slightly paler, antennae annulate; forewing pale brown generally evenly flecked with dark brown, sometimes showing a distinct pattern. Eye of male in frontal aspect with diameter half that of interocular distance. Anterolateral process of fifth sternum length of sternum; with 2 pairs of internal sacs, each distinctly shorter than sternum.

Male Genitalia: Ninth segment with anterior margin nearly vertical. Tenth tergum elongate, tip divided apicomesally; tergite with tip rounded in dorsal, enlarged and upturned in lateral aspect. Clasper with basal segment inflated apicad; apical segment elongate, bluntly pointed. Phallus tubular, base at right angles to stem, width of basal opening 3–4 times width of narrowest part of stem, apex distinctly enlarged, lateral plate slightly longer than wide, ventral margin confluent with ventral margin of stem, tip sharply upturned, in ventral aspect with mesobasal shoulder distinctly produced mesad, shallowly cupped with ventral margin deeply concave, dorsolateral lobe large, about half as long as lateral plate.

Female Genitalia: Eighth sternite elongate, with posteromesal angle rounded, slightly produced; anterolateral angle produced into an apically enlarged lobe. Ninth tergum produced almost directly ventrad, broad laterally. Clasper receptacle deep, pocket-like, with inner surfaces strongly reticulate, produced mesad, and posteroventraliy; in lateral aspect with a deep posteroventral overhang. Vaginal sclerites with a narrow posterior bar and a broader, anterior sclerite, connected centrally by a strongly darkened structure bearing a posteromesal opening. Internal plate more strongly sclerotized mesad than laterally, with lateral arms extended posteriad, with a distinct knob-like depression centrally.
