Redescription ( Fig. 19View FIGURES 10–23, 26View FIGURES 24–26)

Body length 2.8–3.3 mm. Bristles yellow (including bristles on basal section of costa). Small bristle occasionally present in front of anterior dorsocentral. Acrostichal bristle small. Scutum yellow with brown cruciate pattern (holotype and most specimens with transverse stripe incomplete). Scutellum and laterotergites brown. Pleuron and legs light yellow. Head predominantly yellow; anterior margin of frons and antenna light yellow; face white; back of head with one pair of stripes radiating from foramen; ocellar spot brown; face with one pair of faded lateral stripes; gena and parafacial white and silvery tomentose. Abdomen mostly black; tergite 1, usually tergite 2, and sometimes central spot on anterior margin of tergite 3 yellow; cerci and surstylus white. Wing clouded on distal half along R 2+3 and R 4+5 (darkest along R 2+3); R 4+5 and M 1 slightly convergent distally; distance between crossveins no more than length of posterior cross­vein.

Female

As described for male except as follows: “arms” of dorsal cruciate pattern not connected to central stripe; lateral stripes on face absent; epiproct yellow.

Male terminalia ( Figs. 53, 54View FIGURES 53–58, 61View FIGURES 61–66)

As described for C. pleuralis  except as follows: cerci subequal in length to epandrium; surstylus straight with tip strongly tapered and with numerous minute bristles; anterior protuberance on pregonite highly reduced.

Female genitalia ( Fig. 74View FIGURES 71–77)

Length of spermatheca 4.5 times width; distal segment hemispherical with apical depression; next most basal segment wide and ring­like; basal segment poorly sclerotized and cylindrical. Spermathecal duct thin and membranous; as long as basal segment of spermatheca. Ventral receptacle poorly sclerotized and spherical. Subterminal flagellum 12 times length of ventral receptacle.
