Diagnosis. BL of male ~ 1 mm; eyes in males in dorsal view comparable to length of tempora, each composed of moderately large ommatidia ( Fig. 5 View FIGURES 4–9 ).
Description. Body of male ( Fig. 1 View FIGURES 1–3 ) strongly convex, uniformly light brown, covered with setae distinctly lighter than cuticle; BL 0.95–1.14 mm (mean 1.07 mm).
Head ( Figs 4–5 View FIGURES 4–9 ) broadest at eyes, HL 0.20–0.23 mm (mean 0.20 mm), HW 0.20–0.23 mm (mean 0.22 mm); tempora in dorsal view about as long as eyes; vertex and frons confluent, together weakly convex; each eye ( Fig. 5 View FIGURES 4–9 ) large, strongly convex, bean-shaped, with distinct posteromedian emargination, composed of 23 large facets. Punctures on vertex fine, inconspicuous; setae short, sparse and suberect; tempora and posterior margin of vertex densely covered with long and thick bristles. Antennae slender, AnL 0.40–0.53 mm (mean 0.48 mm), antennomeres I and II each strongly elongate, III–VIII each about as long as broad, IX about as long as broad or indistinctly transverse, X distinctly transverse, XI indistinctly narrower than X, slightly elongate.
Pronotum subconical with rounded sides, broadest near posterior third, distinctly rapidly narrowed near anterior 1/5; PL 0.28–0.33 mm (mean 0.29 mm), PW 0.26–0.31 mm (mean 0.29 mm). Anterior margin nearly straight, posterior margin indistinctly bisinuate with weakly convex median third, base lacking pits. Punctures on pronotal disc fine, inconspicuous; setae sparse, moderately long, suberect; sides with sparse, thick and long bristles.
Elytra together oval, broadest indistinctly in front of middle; EL 0.50–0.63 mm (mean 0.58 mm), EW 0.43–0.50 mm (mean 0.48 mm), EI 1.11–1.29; humeral calli distinct, basal impressions short but well developed; apices separately rounded. Punctures inconspicuous; setae much shorter than those on pronotum, sparse, suberect.
Hind wings long, functional.
Legs moderately long and slender, unmodified.
Aedeagus (Figs 27–35) elongate, AeL 0.18 mm; in ventral view broadest in sub-basal region, weakly narrowing distad; apical region variable in shape, in most specimens broadly subtriangular with blunt apex, with median apical projection; endophallus symmetrical and complex, composed of longitudinal tubular component flanked by variously distinct, sclerotized elements of various shapes, in submedian region tubular structure distinctly broadened and forming a large vesicle well-visible in lateral view; parameres slender, each with one long apical and one short subapical seta.
Female similar to male, but with distinctly smaller, less convex eyes distinctly shorter than tempora in dorsal view, each composed of 15 ommatidia; antennae slightly shorter in relation to body, and elytra slightly stouter. BL 0.98–1.14 mm (mean 1.08 mm); HL 0.20–0.21 mm (mean 0.20 mm), HW 0.20–0.23 mm (mean 0.21 mm), AnL 0.40–0.48 mm (mean 0.46 mm); PL 0.25–0.30 mm (mean 0.29 mm), PW 0.28–0.31 mm (mean 0.29 mm); EL 0.53–0.63 mm (mean 0.59 mm), EW 0.45–0.53 mm (mean 0.49 mm), EI 1.14–1.25.
Distribution. Ishigaki-jima and Iriomote-jima of the Yaeyama Islands, SW Ryukyu Archipelago, Japan ( Fig. 44 View FIGURE 44 ).
Etymology. Named after Yaeyama Islands.
Remarks. Himaloconnus klapperichianus yaeyamanus is common in forests of Ishigaki and Iriomote islands, and was collected by sifting moist leaf litter, rotten wood and even abandoned termite nests; it can be also found in flight intercept traps. Among Japanese subspecies, H. klapperichianus yaeyamanus has the largest adults ( Fig. 1 View FIGURES 1–3 ) with eyes ( Fig. 4 View FIGURES 4–9 ) comparable in length to tempora in dorsal view, and composed of ommatidia of an intermediary diameter between those of H. klapperichianus oshimanus and H. klapperichianus okinawanus ( Figs 5, 7, 9 View FIGURES 4–9 ). Aedeagi of these three subspecies are indistinguishable and show some degree of variability in the shape of the aedeagal apex and in endophallic structures (examples among specimens collected within a relatively small area on Mt. Omoto-dake, Ishighaki-jima, are shown in Figs 27–35). Himaloconnus klapperichianus klapperichianus known to occur in Taiwan is most similar to the geographically closest H. klapperichianus yaeyamanus . Adults of H. klapperichianus klapperichianus are as large as the smallest specimens of H. klapperichianus yaeyamanus ; the aedeagus of the nominotypical subspecies is slightly slenderer than that of H. klapperichianus yaeyamanus , and the eye of males in dorsal view is distinctly shorter than the temple (about as long as temple in H. klapperichianus yaeyamanus ), and composed of relatively smaller ommatidia (similar to those of H. klapperichianus okinawanus , Fig. 9 View FIGURES 4–9 ).
