(Figs. 4–6, 15–22)
Diagnosis. Hainokisaruzo fulvus can be distinguished from other congeners by the following traits: 1) forehead narrower than base of rostrum; 2) rostrum stout, 1.65 times (male) or 1.78 times (female) longer than prothorax; 3) elytra mostly covered with dense, black, narrow scales; 4) three elytral bands composed mainly of elliptical white scales, with apical band connected to postmedian band on intervals II, VIII, IX, and X; 5) femoral teeth indistinct; 6) apices of middle and hind tibiae strongly mucronate in male; 7) male ventrite V with a large, deep, transverse, kidney-shaped concavity on disc; 8) pygidium finely punctured, with a shallow concavity in middle in both sexes; 9) spiculum gastrale rather slender and bent rightward in dorsal view.
Description. Male. Dimensions: LB: 2.08 mm, LR: 0.80 mm, WP: 0.72 mm, LP: 0.49 mm, WE: 1.25 mm, LE: 1.50 mm (N = 1 for all measurements). Habitus as in Figs. 4–5.
Vestiture yellowish brown in general appearance. Head moderately covered with narrow, white scales that are weakly dilated toward apex. Rostrum covered with white scales in basal 2/3 and fine hairs in apical 1/3. Prothorax mostly covered with narrow, white, elliptical scales; dorsum with a narrow, white, median stripe running from basal to apical margin; stripe composed mostly of narrow scales except basal part, which is composed of elliptical scales; dorsal prominences furnished with short, brownish, narrow scales; each side with an irregular spot of elliptical scales. Elytra mostly covered with dense, black, narrow scales, bearing a reverse subtriangular patch of narrow, white, elliptical scales in basal part between intervals I–IV, with three white wide bands in antemedian, postmedian and apical portions; each band composed of elliptical scales mingled with narrow scales; postmedian band connected with apical band on intervals II, VIII, IX and X; each interval containing 1–4 rows of scales. Legs moderately covered with narrow to lanceolate, white scales; corbel of each tibia fringed with yellowish-gray setae. Meso- and metasterna laterally moderately covered with narrow, white, elliptical scales; centre evenly covered with white acicular to lanceolate scales. Venter (Fig. 6) moderately covered with white lanceolate scales; ventrite I sparsely mingled with fine light-colored hairs on disc; ventrite V sparsely covered with slender, suberect hairs on disc, fringed with minute hairs on apical margin, bearing a tuft of long hairs on each side. Pygidium moderately covered with fine yellowish-gray hairs.
Head finely and closely punctured; forehead narrow, 0.94 times as wide as base of rostrum. Rostrum slen- der, 1.65 times longer than pronotum, evenly and moderately curved; dorsum evenly and moderately punctured. Antennae inserted before middle of rostrum; scape slender, 1.37 times longer than funicle, 12.74 times longer than wide, produced into a short lamina at apex; length ratio of funicular segments I: II: III: IV: V: VI: VII = 2.76: 2.46: 1.57: 1.32: 1.03: 1.08: 1.00, width ratio of funicular segments I: II: III: IV: V: VI: VII = 1.26: 0.78: 0.89: 0.73: 0.89: 1.03: 1.00; club subrhomboidal, not constricted at base.
Prothorax 0.32 times as long and 0.57 times as wide as elytra, 1.47 times wider than long, widest at base, gradually and straightly narrowing toward subapical constriction; dorsum coarsely punctured with a relatively deep median sulcus, tubercules narrowly and strongly prominent; basal margin weakly bisinuate. Elytra 3.08 times longer and 1.74 times wider than pronotum, 1.20 times longer than wide, widest just at humeri, gradually and straightly convergent toward subapical calli; striae rather deep; intervals wider than striae, prominences less-developed, moderately granulate. Legs slender. Femora clavate, each armed with a vestigial tooth; fore femora slightly stouter than middle and hind femora. Fore tibiae simple at apex, lacking mucrones; corbels short, slightly dilated outward. Middle and hind tibiae weakly mucronate at apex; corbels moderate in length, slightly dilated outward. Tarsi with segment V slender; claws obtusely appendiculate.
Ventrite I (Fig. 6) moderately punctured and shallowly concave on disc; ventrite II 0.73 times as long as I, two times longer than III and moderately punctured; ventrites III and IV minutely and densely punctured; ventrite V relatively narrow, 4.09 times wider than long, equivalent to III and IV together in length, with a large, deep, transverse, kidney-shaped concavity on disc. Pygidium wide, 1.85 times wider than long, opaque, finely punctured and shallowly concave; upper flange downward arcuate on each side. Sternite IX (Fig. 17) slightly longer than wide; spiculum gastrale rather slender, much longer than aedeagal body or its apodeme, bent rightward. Tegmen (Fig. 18) with a relatively stout apodeme, about 2/3 as long as diameter of tegminal ring, subparallel. Aedeagal body (Figs. 15, 16) slender, subparallel in basal 3/4, gradually constricted and bluntly projected toward apex, relatively thin with a strong, even, downward curve in profile. Endophallus (Fig. 15) with several irregular sclerites near base and many dentiform sclerites in middle and a longitudinal spiculate field in apical half.
Female. Dimensions: LB: 1.98 mm, LR: 0.86 mm, WP: 0.73 mm, LP: 0.49 mm, WE: 1.22 mm, LE: 1.40 mm (N = 1 for all measurements).
Rostrum much more slender than in male, 1.78 times longer than prothorax. Antennae inserted at middle of rostrum. Prothorax 1.50 times wider than long. Elytra 1.15 times longer than wide. Tibiae simple, not mucronate on any legs. Ventrites I and II moderately inflated, opaque, evenly and moderately punctured. Ventrite V wider, 4.22 times wider than long, slightly inflated, without concavity. Pygidium 1.89 times wider than long, shallowly concave. Ovipositor (Fig. 21) with robust hemisternites, nearly two times longer than styli; styli apicolaterally inserted, moderate in length, nearly two times longer than wide. Tergite VIII (Fig. 19) moderately setiferous in apical 1/3. Sternite VIII (Fig. 20) furnished with several minute setae; arms subparallel, nearly 1/4 as long as apodemes, slightly longer than hemisternite and stylus combined, slightly basally fused, with inner margin slightly divergent; apodemes slender; moderately divergent near apex. Spermatheca (Fig. 22) with cornu slender, moderately attenuate, rounded at apex; collum broadly obliquely convex upward; ramus less-marked; insertions of duct and gland close to each other. Otherwise practically as in male.
