Cleotomiris sakaeratensis n. sp.

( Figs. 1 C, F, 2−3)

Diagnosis. Recognized by its antlike body ( Fig. 1 C); small size; fuscous general coloration; sparsely distributed vestiture on matte dorsum; large eye; narrow vertex; wholly brown, slender antenna; a median knob-like process on ostiolar peritreme ( Fig. 1 F); and a whitish, crescent mark across corium. The new species is most similar in general appearance to C. miyamotoi Yasunaga known only from Okinawa Island of the Japanese Ryukyus, but C. sakaeratensis can be distinguished from it by the more fuscous general coloration, less shining pronotum and scutellum, a knob-like projection on the ostiolar peritreme, and longer apical appendage of the endosoma.

Description. Body generally fuscous, elongate, antlike; dorsal surface almost entirely matte. Labium shiny chestnut brown, somewhat tinged with red, reaching apex of mesocoxa. Pronotum weakly constricted at middle, with narrow collar; pleura chocolate brown, somewhat shagreened; ostiolar peritreme pale at ventral half, with a median, knob-like projection (cf., Fig. 1 F). Hemelytron with a creamy white, crescent mark across clavi just posterior to apex of scutellum (cf., Fig. 1 C); membrane dark smoky brown. Coxa creamy yellow, generally shining; entire procoxa and basal 1/3 of mesocoxa dark brown. Leg dark brown; trochanters and bases of meso- and metafemora yellow; tibial spines sparse; tarsi pale brown. Abdomen wholly shiny dark brown, in female lacking any ventral spine. Male genitalia as in Fig. 2 ; pygophore with a median spine ventrally ( Fig. 3 ); endosoma smooth; secondary gonopore weakly developed.

Measurements (♂/♀): Total body length 2.69/ 2.92; length from apex of clypeus to cuneal fracture 2.01/ 2.03; width of head across eyes 0.71/ 0.64; width of vertex 0.20/ 0.28; lengths of antennal segments I-IV 0.20, 0.72, 0.44, 0.36/ 0.22, 0.74, 0.49, 0.37; labial length 1.01/ 1.08; mesal length of pronotum including collar 0.60/ 0.65; basal width of pronotum 0.85/ 0.86; maximum width across hemelytron 0.82/ 1.09; and lengths of metafemur, tibia and tarsus 0.98, 1.32, 0.29/ 0.98, 1.42, 0.29.
