Diagnosis
Diagnosis. Distinguished from other congeners by the somewhat (posteriorly) ovoid body, grayish brown basic coloration, small eyes, short, blunt-tipped median projection on frons, and noticeable skull-like markings on the hemelytron (Fig. 1 B, circled image).
Description
Description. Body generally grayish brown, somewhat ovoid; dorsal surface mat or shagreened, with sparsely distributed, long, silky, erect setae and short, reclining, woolly setae. Head whitish, with irregular sanguineous stripes laterally; frons with a short, thumb-like, blunt-tipped median projection; eye small; vertex wide. Antenna grayish brown, partly tinged with red; segment I coffee brown. Labium shiny dark brown, long, extending beyond apex of metacoxa, reaching abdominal sternum VI or VII. Pronotum with white basal margin; collar area with sanguineous spots; mesoscutum with four tooth-like, dark markings; scutellum arched mesially, with pale apex; pleura dark brown, rather shiny; episternum tinged with red; ostiolar peritreme creamy yellow. Hemelytron irregularly speckled, with a set of four dark, skull-like markings on clavus and corium (Fig. 1 A–B); cuneus dark brown, rather strongly deflected at cuneal fracture; membrane dark smoky brown. Coxae and legs dark brown, except for pale metacoxa, all tibiae and tarsi brown. Abdomen unicolorously dark brown. Male genitalia (Figs. 4– 6): Genital segment slender (Fig. 4). Left paramere sensory lobe with a broad basal protuberance (Fig. 5). Phallotheca J-shaped, with smooth apex (Fig. 4). Endosoma long, spiral and subbasally coiled, terminated in an apical, spinulate lobe, with notched apical margin (Figs. 5 & 6). Female genitalia (Fig. 7): Lateral margin of dorsal labiate plate folded; sclerotized rings indistinct. Measurements. 3 /Ƥ: Total body length 3.24 / 3.50; length from apex of clypeus to cuneal fracture 2.54 / 2.88; head width across eyes 0.60 / 0.63; vertex width 0.30 / 0.33; lengths of antennal segment I–IV 0.45, 1.20, 0.90, 0.75 / 0.50, 1.38, 1.08, 0.90; labial length 1.95 / 2.13; basal pronotal width 1.01 / 1.02; width across hemelytron 1.28 / 1.34; and lengths of metafemur, tibia and tarsus 1.20, 1.80, 0.30 / 1.35, 1.95, 0.33.
Etymology
Etymology. From Greek, kranion (= skull), referring to the peculiar pattern of the hemelytron (as in circled image, Fig. 1 B).
