Redescription

COLORATION. General body coloration light brown; dorsal and ventral surface densely punctured. Posterior portion of dorsal head, humeral angles, and foveae black. Legs light brown.

HEAD. As long as wide; mandibular plates and clypeus subequal. Apex of labium reaching metacoxae; fourth labiomere darker than preceding; proportion of labial segments: I<II=III>IV. Antennae light brown; proportion of antennal segments: I<II>III <IV>V.

THORAX. Anterolateral margins of pronotum pale, crenulated, and rectilinear; humeral angles acute. Scutellum triangular, frenal portion longer than postfrenal portion; foveae elongated, more than 3 × the diameter of ocelli. Corium longer than scutellum, reaching posterior margin of abdominal segment VI; hemelytral membrane light brown surpassing apex of abdomen. Peritreme disc-type, rectilinear; metapleural evaporatorium surrounding peritreme, not reaching lateral margin of pleura; mesopleural evaporatorium concentrated in two different places, not reaching lateral margin of pleura ( Fig. 8e ); presence of pair of metasternal processes holding apex of labium, region between and surrounding processes black.

ABDOMEN. Apex of connexival segments acute and projected posteriorly. Abdominal tubercle short, not reaching metacoxae.

MALE GENITALIA. Pygophore cuplike; anterior opening oval; dorsal rim sinuose; superior layer of ventral rim concave in ventral view; inferior layer of ventral slightly projected; head of paramere sickle-like, with acute apex; pseudoclasper small and slender, tongue-like shaped. Phallus with thecal shield distinctly longer and wider than basal theca; processes of conjuctiva absent; vesica U-shaped.

FEMALE GENITALIA ( Fig. 8n ). Valvifers 8 as long as wide, juxtaposed, posterior margins rectilinear; valvifer 9 rectangular; laterotergites 9 longer than wide, rounded apically, surpassing segment X.

MEASUREMENTS. (n =1, NHMUK 010935723) Head length: 1.61, width: 1.88; pronotum length: 2.27, width: 5.09; scutellum length: 3.05, width: 2.82; antennomeres missing; labial segments length: I 0.93, II 1.16, III 1.16, IV 0.85 (0.5–0.6); abdominal length: 3.65, width: 4.01; total length: 9.75.
