Wumea Carvalho

Wumea Carvalho, 1987: 186 .

TYPE SPECIES: Wumea clypealis Carvalho, 1987 (original designation) .

DIAGNOSIS: Recognized among other Orthotylini by the following combination of characters: elongate parallel-sided body ( fig. 1e, f ); projecting clypeus; strongly carinate posterior margin of head projecting over anterior margin of pronotum; disc of pronotum shining with weak rugullae; posterior margin of pronotum broadly emarginated; and relatively long metathoracic legs. Distinguished from similar genera by gently sloping frons and branched left paramere in males ( figs. 6c , 7c ).

REDESCRIPTION: Male: General Aspect: Macropterous, elongate, parallel-sided, total length 4.66–5.40; length from apex to clypeus to cuneal fracture 3.40–3.89; width across humeral angles of pronotum 1.01–1.13. Coloration and vestiture ( fig. 1e, f ): Dorsally reddish brown; ventrally darker; antennae and legs yellowish brown with red maculation on apices of metafemora; membrane of forewing moderately suffused with brown; veins reddish brown. Dorsum essentially glabrous; metepisternum with field of dense microchaetae; few hyaline, short setae present on dorsum; legs and antennae with fine, short, hyaline setae. Structure: Head moderately projecting in front of eyes; posterior margin convex; posterior margin strongly carinate, projecting over anterior margin of pronotum; frons flat posteriorly becoming gently declivent anteriorly; clypeus distinctly projecting in front of frons; gena and maxillary plates extending anteriorly; buccal cavity obovate, posterior margin well separated from anterior margin of prosternum; eyes occupying almost all of total head height in lateral view, posterolateral margin slightly separated from margin of pronotum; antennae inserted just below dorsal margin of eye. Antennae elongate, gracile; segment I subequal to length of pronotum, vasiform; segment II cylindrical, elongate, three times longer than segment I; segment III and IV gracile, often corkscrewed in dry specimens. Labium reaching metacoxae. Pronotum elongate, trapeziform, slightly longer than broad, weakly rugose; pronotal collar, thin, shallowly emarginate dorsally; lateral margins slightly emarginate; posterior margin distinctly sinuate with medial emargination; disc weakly convex, vaguely separated into anterior and posterior lobes by shallow sulcus; calli obsolete, undifferentiated. Mesoscutum not exposed. Scutellum triangular, slightly convex. Hemelytra elongate, parallel-sided to posterior margin of cuneus; cuneus two to three times longer than broad; vein of large cell with short spur vein along posterior border. Metathoracic spiracle large with evaporative areas; ostiole lenticular, placed anteriorly on metepisternum; peritreme swollen, evaporative area extending to posterior margin of metepisternum, relatively flat posteriorly. Legs extremely elongate; claws moderately curved with apically convergent parempodia. Genitalia ( figs. 6 , 7 ): Genital capsule large, subconical; ventral projection acute to broadly rounded. Left paramere divided into two main branches, sometimes with tubercles. Right paramere variable. Phallotheca relatively simple, slightly sclerotized, sometimes with distal angular projection. Aedeagus relatively simple; ductus seminis with heavily sclerotized swollen area prior to secondary gonopore; secondary gonopore elongate, elliptical, surrounded by papillate membrane.

FEMALE: Similar to males. Ovipositor approximately one-third length of abdomen; subgenital plate narrowly triangular with acute distal margin, roughly one-third length of ovipositor.
