Cleotomiroides ishikawachui Yasunaga & Duwal , sp. nov.

( Figs 33–35 , 74−76 , 192–195 )

Type material. HOLOTYPE: ♁, INDONESIA: JAVA: Malang , Buring, S 07°59′40.0″–42.0″ E112°39′38.0″–39.1″, 513–518 m alt., 24 Aug 2005 (afternoon), T. Ishikawa ( TUAK) ( AMNH _ PBI 00380631 ).

Differential diagnosis. Recognized by its relatively large size; fuscous basic coloration contrasting with rusty apical half of the clavus ( Fig. 33 ); conspicuous white fascia and maculae on hemelytron ( Figs 33, 35 ); and form of male genitalia ( Figs 192−195 ). This new species can be distinguished from two known congeners by the fuscous general coloration, broad hypophysis of the left paramere ( Fig. 193 ), and elongate apical appendage and spinulate flap-like process of the endosoma ( Fig. 195 ).

Description. Male. Body generally blackish brown, relatively small, myrmecomorphic; dorsal surface weakly shining, widely shagreened or roughened, with sparsely distributed, woolly semierect setae and with more sparsely distributed, longer, upright setae ( Fig. 35 ). Head dull brown, oblique; eyes large; vertex narrowly carinate basally. Antenna dull yellowish brown, almost linear; segment II slightly incrassate toward apex; segments III and IV brown, weakly terete. Labium shiny dark brown, reaching subapical part of mesocoxa. Pronotum with a narrow collar, narrower than all antennal segments; pleura shiny fuscous, minutely rugose; ostiolar peritreme strongly protruding medially, with ivory white posterior margin of evaporative area. Hemelytron with a white, continuous fascia posterior to scutellum across clavus, corium and exocorium ( Fig. 33 ); apical 1/4 of corium rusty; membrane smoky brown, except for pale, translucent base. Coxae and legs brown or darker; meso- and metacoxae widely pale brown; pretarsus with rather fleshy, apically convergent parempodia ( Fig. 76 ). Abdomen wholly dark brown, somewhat shagreened ( Fig. 34 ). Male genitalia ( Figs 192–195 ): Genital segment with a ventral spine ( Fig. 192 ). Left paramere with rather stout hypophysis ( Fig. 193 ). Phallotheca almost straight, tapered, with a spine near apex ( Fig. 194 ). Endosoma J-shaped, stout, with an elongate apical appendage and a weakly sclerotized, rounded flap-like process beside thick-rimmed secondary gonopore ( Fig. 196 ).

Measurements. Male (holotype): Total length of body 3.33; head width including eyes 0.72; vertex width 0.21; lengths of antennal segments I–IV 0.30, 1.07, 0.60, 0.44; total labial length 1.28; basal width of pronotum 1.02; maximum width across hemelytron 1.05; and lengths of metafemur, tibia and tarsus 1.14, 1.70, 0.30.

Female. Unknown.

Etymology. Named after a Japanese heteropterist, Dr. Tadashi (nickname Chu) Ishikawa who collected the holotype specimen of this new species; a noun in genitive case.

Biology. Unknown; Dr. Ishikawa collected the holotype female by sweep-netting an unidentified broadleaf tree.

Distribution. Indonesia: Java (this paper).
