Coelana Kramer, 1964 : 261 , 269–270 (key to genera, description, key to species). Type species: Neocoelidia modesta Baker , 1898 . Designated by Kramer, 1964 : 269 . Diagnosis. Color stramineous to yellow with small black spot at apex of crown ( Figs. 1 , 10 ); carina present in transition between crown and frons; posterior margin of pronotum emarginated, broadly indented ( Figs. 1 , 10 ); forewing with venation indistinct, except for claval suture and apical cells ( Figs. 4 , 13 ); male genitalia: pygofer greatly inflated, with large ventral hook, a pair of long inner processes dorsally, and laterally with a long ventrodorsal suture ( Figs. 5 , 14 ); connective Y-shaped ( Figs. 8 , 17 ) and aedeagus simple, without processes ( Figs. 9 , 18 ); anal tube with a pair of ventral processes ( Figs. 5 , 14 ). Description. In dorsal view, body approximately cylindrical, not flat. Head. Crown almost quadrangular, slightly projected anteriorly and slightly wider than long; median length of crown approximately one half of transocular width and approximately equal to interocular width; anterior margin broadly angular, with carina in the transition between crown and frons; lateral margins, adjacent to compound eyes, elevated (not at the same level of the dorsum of compound eyes) and carinate; surface flat, smooth, without grooves, with weak coronal maculae at the base of crown, close to compound eyes; coronal suture indistinct ( Figs. 1 , 10 ); ocelli located on anterior margin of head, in the transition between crown and frons, closer to compound eyes than to midline, above antennal ledges; in lateral view, antennal ledges oblique and carinate ( Figs. 3 , 12 ); antennae setaceous, scape and pedicel enlarged, flagellum longer than basal half of forewings ( Figs. 2–3 , 11–12 ); frons with length approximately two times basal width, profile convex, muscle impressions generally indistinct, not swollen on the central portion of base; frontogenal sutures reaching ocelli; apical margin of maxillas not extending beyond apex of clypeus; lorum small, approximately halfmoon shaped, inferior margin not reaching apical margin of clypeus; gena partially concealing proepisternum, only apex visible in anterior view; epistomal suture distinct and complete, slightly curved; clypeus almost rectangular, lateral margins parallel, generally without a gibbosity in lateral view, and apical margin straight ( Figs. 2–3 , 11–12 ). Thorax. Pronotum slightly wider than head, width between humeri slightly larger than transocular width; median length approximately one third of width between humeri; lateral margins rounded and posterior margin emarginated, broadly indented ( Figs. 1 , 10 ); dorsal surface with transverse grooves; dorsopleural carina complete and evident; in ventral view, mesothorax moderately swollen; scutellum ( sensu Young 1968 ) as long as maximum width, with distinct preapical fold ( Figs. 1 , 10 ). Forewing ( Figs. 4 , 13 ) with rounded apex, without punctuations, hyaline, about 3–3.5 times longer than greatest width; venation indistinct, except for claval suture and apical cells; four apical cells, all almost rectangular, first larger than second, third slightly enlarged apically; second and fourth apical cells approximately same distance to base, closer to forewing base than third cell; anteapical cells distinct or not; appendix narrow, extending only along first apical cell. Hindwing with three apical cells, R4+5 and M1+2 apically convergent, fused, forming a single vein. Hindleg: femoral setal formula 2+2+0; tibial row PD with long setae little separated amongst themselves, distributed throughout length of tibia, intercalary setae absent; row AD with long and robust setae in form of spines, with two or more small intercalary setae present; row AV with setae moderately long, distributed only on apical two thirds, intercalary setae absent; row PV densely bristly, with short setae at base, becoming progressively longer toward apex; first tarsomere as long as combined length of two distal ones, plantar surface with two parallel rows of short setae. Abdomen. Male genitalia: pygofer greatly inflated, longer than subgenital plates, with large ventral hook, a pair of long inner processes dorsally, and laterally with a long suture, extending from ventral margin to near dorsal margin ( Figs. 5 , 14 ); subgenital valve entirely fused to subgenital plates; subgenital plates fused on the basal and median thirds, separated only on apical third ( Figs. 6 , 15 ); styles simple, not bifurcated, with sclerotized hook-like apex, curved ventrally ( Figs. 7–8 , 16–17 ); connective Y-shaped, articulated to base of aedeagus ( Figs. 8 , 17 ); aedeagus simple, without processes ( Figs. 9 , 18 ); anal tube with a pair of ventral processes ( Figs. 5 , 14 ). Total length (body + forewings). 6.0– 7.5 mm . Geographical distribution. Argentina , Bolivia and Brazil . Comments. This genus is similar to Coelidiana Oman regarding the external morphology and general color of the species. It possesses some diagnostic characters that easily separate it from the other genera: general color stramineous to yellow with a small black spot at apex of crown and the characteristic male genitalia, mainly the morphology of the pygofer and anal tube.
