Basicosta yellow to orange............................................................................. 2 - Basicosta brown to black................................................................................ 3 2. Genal dilation with black vestiture; katepisternal formula 1+1 (Whitworth, 2010, fig. 9); base of wing dark, infuscated along costa to apex of costal cell, angling back to anterior edge of basal medial and posterior cubital cells (as in Fig. 7 ); male frons broad, averaging 0.29 (0.028–0.30/5) of head width; male and female genitalia unique (Whitworth 2010, figs. 10, 11, 18), see detailed discussion and illustrations in Whitworth (2010); known only from West Indies in Cuba , Dominican Republic , and Jamaica .................................................................................... C . maestrica - Genal dilation with reddish vestiture on front half or more; katepisternal formula 2+1 (Whitworth, 2010, fig. 8); base of wing hyaline; male frons much narrower, averaging 0.075 (0.07–0.08)/4 of head width; characters illustrated in Rognes (1991, figs. 132, 139–148) and Mello (1962, figs. 1–10) ; known in the Neotropical Region from Argentina , Chile , Cuba , Falklands, Mexico , Panama , Uruguay ........................................................................... C . vicina 3. Three postsutural intra-alar setae; lower calypter, rim and setal fringe whitish, especially near distal end ( Fig. 3 ) (also in C . lopesi ); parafacial uniformly dark brown or black; male frons narrow, less than half the width of the parafacial at widest, 0.031 (0.030–0.031)/5 head width; surstylus broad in lateral view ( Fig. 14 ), from rear, cerci often distinctly y-shaped ( Fig. 15 , yshape not distinct in photo); female, width of parafacial about equal to width of first flagellomere, 1.3 (1.1–1.5/5); known only from Costa Rica , El Salvador and Mexico ( Fig. 1 )..................................................... C . triseta - Two postsutural intra-alar setae; if three, then the first very tiny (sometimes in C . irazuana ); lower calypter rim and fringe brown to reddish brown (except white in C . lopesi ); lower half of parafacial orange color; male frons width variable; surstylus narrower in lateral view, from rear, parallel or V-shaped; female, parafacial 1.5– 2x width of first flagellomere (except in C . irazuana ); ranges do not overlap except in C . irazuana ......................................................... 4 4. Rim of lower calypter pale with whitish setae; genal groove red (also often red in C . irazuana , but ranges do not overlap); supravibrissal setae on facial ridge weaker, ascending from the vibrissa about halfway to antennal base ( Fig. 5 ); male frons broad, about 1.6x width of parafacial, 0.066 (0.06–0.07/5) of head width; male surstylus slender in lateral view, cerci shorter than surstyli ( Figs. 10, 11 ); female, T5 with no incision; known only from Brazil and Uruguay ( Fig. 2 )............ C . lopesi - Rim and fringe of lower calypter usually darker, reddish, brown or black (as in Fig. 4 ); genal groove usually dark brown to black; setae on facial ridge stronger, usually ascending up from the vibrissa two-thirds or more toward antennal base ( Fig. 6 ); other characters variable................................................................................ 5 5. Known only from Central America ; genal groove usually reddish like lower parafacial; anterior half of gena often reddishbrown; setae on occiput yellowish; sometimes a third tiny postsutural intra-alar seta (usually much smaller than in C . triseta ); male frons much narrower than width of first flagellomere, 0.034 (0.03–0.04/5) of head width; width of parafacial about equal to width of first flagellomere; surstylus slender in lateral view; cerci narrow in posterior view, about as long as surstylus ( Figs. 8, 9 ); female parafacial 1.4x or less width of first flagellomere; known from higher elevations in Costa Rica , El Salvador , Guatemala and Mexico ( Fig. 1 ) and is likely present in other Central American countries....................... C . irazuana - Known only from South America ; genal groove usually dark brown to black, concolorous with gena color; gena all black to dark brown; white silky setae on occiput, extending into rear of postgena area; only two postsutural intra-alar setae; male frons wider than first flagellomere, 0.102 (0.09–0.12/5) of head width; width of parafacial about 1.9x width of first flagellomere; surstylus broader in lateral view; cerci broad in posterior view, shorter than surstylus (see Figs. 12, 13 ); female parafacial broad, about twice the width of first flagellomere, 2.3 (2.1–2.5/5); at high elevations in Argentina , Bolivia , Colombia , Ecuador , Peru , Venezuela ( Fig. 2 ).....................................................................
