Description
Description. Body robust. Crown rounded at anterior margin, with a median black apical spot; coronal suture distinct, reaching anterior margin of vertex (Figs 1, 19). Ocellus present. Face elongated and convex in profile, lateral frontal suture present (Figs 2, 20). Pronotum wider and longer than crown (Figs 1, 19). Scutellum yellow with basolateral triangles and apex black; scutoscutellar sulcus distinct, not reaching lateral margin of scutellum (Figs 1, 19). Forewing rounded apically, apical cells less than one-third total length, RP and MP' separated at base, both originated from r cell, MP+CuA' from m cell, width of c cell equal with r cell (Figs 4, 22). Hindwing with CuA bifurcated, the branching point at or distad of coalescence of CuA with MP (Figs 5, 23). Male ventral abdominal apodemes well developed, rounded apically, reaching segment IV or V (Figs 7, 25). Male pygofer long, dorsal margin strongly concave, lightly sclerotized and less pigmented in basal 2/3 but more sclerotized apically, apex with few rigid microsetae; pygofer appendage absent (Figs 9, 27); dorsal bridge short (Figs 8, 26). Subgenital plate longer than pygofer (Figs 6, 24), basal broad, with an oblique line of macrosetae; outer margin slightly expanded at midlength and bearing few moderately long and stout setae forming the basal group (Figs 10, 28). Paramere shorter than pygofer, curved, narrowed from near midlength to apex, laterally with few setae, apex with teeth and sensory pits (Figs 14, 31). Aedeagal shaft elongated, curved posteriorly, with symmetrical flanges, gonopore apical on ventral surface; basal apodeme absent; preatrium developed (Figs 11, 12, 13, 17, 18, 29, 30, 34, 35). Connective with base broad, apex narrow (Figs 16, 33). Anal tube as in Figs 15, 32.
