Platocerella sordida sp. nov. — Costa Rica

Amended diagnosis (revised from Fennah 1952). Vertex small (in dorsal view), triangular; face with lateral carinae of frons closely appressed, frontoclypeal suture slightly convex; in lateral view head rounded, following the anterior margin of eyes. Eyes reniform, not deeply excavate. Antennae elongated, well exceeding anterior margin of head, antennal appendage absent; scape very short, pedicle elongated (surpassing anterior margin of head), subcylidrical, flagellum inserted apically. apically. Pronotum very narrow medially (in dorsal view), broadened laterally, posterior margin deeply angulately excavate. Mesonotum (lateral view) moderately convex, tricarinate. Forewing elongate, spatulate; composite vein ScP+R+MP forming common stem distad of basal cell, RP+MP forked from SC+RA a little basad of fusion of Pcu+A 1 in clavus; RP forked from MP near wing midlength; composite vein Pcu+A1 reaching CuP before wing margin; branching pattern RA 2-branched, RP 3-branched, MP 8-branched, and CuA 2- branched, anastomosed to form closed C5 (procubital) cell. Pygofer with laterodorsal margin angulately produced, medioventral process present or absent. Gonostyli rather elongate, subspatulate, with shallow, dorsal lobe basally with many robust setae and more distal short, stout curved spines. Anal segment of male (lateral view) elongate, narrow, distally downcurved.
