Externally similar to A. ohtsukai, A. hikosanus, and A. kurosawai, but distinguished from A. ohtsukai by a larger body (Figs 1–3), a pair of small depressions on the pronotum (Figs 4–5), and an aedeagal apex with an acute right edge (arrows with an asterisk in Figs 6, 9; see also Morita 1993: Fig. 5); from A. hikosanus by the absence of a denticle at the aedeagal apex (arrows with two asterisks in Figs 10–11); and from A. kurosawai by developed spiny sclerites (Figs 20–22). Description. Body length (measured from the apex of clypeus to the elytral end): ď, 9.78–10.79 mm (mean ± SD; 10.31±0.27 mm; n= 11); Ψ, 10.48–11.35 mm (mean ± SD; 10.97±0.32 mm; n= 5). Dorsal surface (Figs 2–3) black and shiny, without metallic luster. Appendages dark brown. Head widest at mid-eye level, with length from clypeal apex to neck base 0.71–0.76 times longer than width between eyes; mandibles short, with grooved surface; labrum 6 -setose, with anterior margin almost straight; frontal impressions large and deep, with posterior ends reaching to those of the eyes; surface of frontal impressions markedly punctate; frons sparsely punctate; two pairs of supraorbital setae, anterior pair at mid-eye level and posterior pair at the level of the basal 1 / 3 of tempora; longitudinal line between eye and supraorbital seta deep and long, with posterior ends reaching apical 1 / 3 of tempora; eyes convex and almost the same length as tempora; tempora swollen, almost smooth at dorsal and lateral sides, but punctate at ventral side; mentum tooth bifid, with a pair of setae at base; submentum with two pairs of setae. Antennae long; segments 1–2 without pubescence; one seta on segment 1; four setae on segment 2. Pronotum (Fig. 5) cordate, widest at apical 1 / 3, 0.78–0.86 times longer along median line than wide at widest point; anterior margin weakly emarginated, with width between apices of anterior angles 0.62–0.70 times wider than pronotal width at widest point; posterior margin almost straight, with width between apices of posterior angles 0.66–0.71 times wider than pronotal width at widest point; lateral margins arcuate at apical 2 / 3, slightly sinuate at basal 1 / 3; anterior angles barely produced; posterior angles almost right-angled, with apices narrowly rounded; two pairs of marginal setae, anterior pair at apical 1 / 3 and posterior pair at the tip of hind angle; surface with punctations at anterior and posterior margins and laterobasal impressions; small depression at point midway between median line and anterior marginal seta; laterobasal impression single and deep; median line deep in mid-region, shallow near the anterior and posterior margins. Elytra convex, widest behind middle, 1.56–1.68 times longer than wide at widest point; shoulders rounded, without a denticulate tooth; apices narrowly rounded but not denticulate; intervals convex near base, almost flat at apex; scutellar stria present, but not connected to stria 1; one dorsal pore at the anterior end of stria 1; three dorsal pores on interval 3, all adjoining stria 3; hind wings reduced. Ventral side with punctations at ventral side of tempora, prosternum, episternum, and lateral sides of sterna 2–7; sternum 7 with a pair of setae in males, two pairs in females. Legs stout; hind tarsomeres with three to four setae on ventrolateral margins. Aedeagus (Figs 8–10, 23) stout, bent in somewhat obtuse angle near the base, twisted to right side; dorsal surface membranous except for apical part; apical part bent in the right lateroapical direction; right corner of apical part protruded ventrally, left one dorsally. Right paramere broad. Left paramere broad, larger than right one. Endophallus (Figs 12–14, 22) stout and straight, directed right dorsolaterally; left pigmented band short, weakly sclerotized; left laterobasal lobe large; ligula small, weakly arcuate, with apex narrowly pointed; dorsal lobe markedly large, with dorsum bearing spiny sclerites; both right and left subapical lobes moderatesized, adjoining dorsal lobe; right apical lobe moderate, adjoining dorsal lobe; left apical lobe small; gonoporal piece large. Vagina (Figs 15–16) with strong pigmentation at base; bursa copulatrix markedly large, with anteroposteriorly elongated bursal sclerite on ventral surface; irregular pigmentations on dorsoapical surface of bursa copulatrix; spermatheca almost straight and elongated, with apex weakly expanded; spermathecal gland connected to basal 1 / 6 of spermatheca.Published as part of Sasakawa, Kôji & Toki, Wataru, 2007, Apatrobus osuzuyamanus sp. nov., a new patrobine species from Japan, with a comparative study of the male genital morphology of the tribe Patrobini (Coleoptera: Carabidae), pp. 41-48 in Zootaxa 1615 on pages 43-46, DOI: 10.5281/zenodo.17906
