Styringomyia simplex , male specimen from Brazil (Mato Grosso, Diamantino). Three­dimensional structure of terminalia, dorsolateral view. Abbreviations: aed, aedeagus; aed sh, aedeagal sheath; goncx, gonocoxite; gonst, gonostylus; S9, ninth sternite, vb, ventral branches of aedeagal sheath. DESCRIPTION. Dimensions. See Table I. Morphology. Ninth sternite ( Fig. 32 ): abruptly narrowed at apex. Tenth tergite ( Fig. 22 ): posterior margin trilobulate; medial lobe triangular, broader than long. Gonocoxite (Figs. 31­32): distal half conical, abruptly narrowed; longest and more stout hairs along the distal parts of dorsal margin to apex; other hairs slender, variable in length, the longest along the lateral margin. Gonostylus ( Figs. 14 , 31­32): more or less S­shaped, bearing two strongly sclerotized apical extensions ( Fig. 14 , III, IV); extension III less developed than extension IV; medial face with a long and stout hair originating near base of extension IV; other hairs of medial face slender and shorter; hairs of lateral face long and slender. Aedeagal sheath (Figs. 31­32): without lateral lobes; dorsal crest four­pointed; space between medial points narrow; apex of each point disposed nearly side by side; ventral branches long, broad at base, abruptly narrowed at tip. Female cercus ( Fig. 9 ): narrowing gradually toward tip; anterior portion of ventral margin interrupted by a constriction.
