Diagnosis. Aleochara lata is a distinct species among the Japanese congeners and can be easily distinguished from all of them as follows: body large-sized, blackish in coloration including base of antennae; dorsal surface glossy, rather deeply punctured; inter coxal process of metaventrite large, broadly and weakly rounded apically; elytra without blackish maculations laterally; abdominal tergite and sternite VIII strongly transverse, with numerous macrosetae; median lobe of male aedeagus narrowly elongate, complex sclerites restricted to apical 1/3 of median lobe, and by; female spermatheca with reticulate basal portion of spermathecal stem. Found in mountainous area of mainland, or adjacent large islands, in Japan.
Redescription. Measurements (in mm, n = 20): BL = 7.40 (6.29–8.51); HL = 1.04 (0.89–1.23); HW = 1.15 (0.96–1.31); PL = 1.43 (1.22–1.67); PW = 2.03 (1.71–2.37); EL = 1.19 (1.00–1.43); EW = 2.40 (1.95–2.75).
Body (Figs 3, 12): fusiform, robust, large to very large in size; dorsal surface rather strongly glossy, pubescent, without any types of micro-reticulation, rather strongly punctured. Color (Figs 3, 12): uniformly complete black, including elytra uniformly; antennae with antennomeres I–IV black, antennomeres V–XI slightly lighter than those of I–III due to dense covering of minute whitish setae; mouth parts and legs dark reddish brown to brownish brown; pubescence yellowish brown.
Head (Fig. 21): semicircular, as long as width (HW/HL = 1.11, n = 20), widest at posterior part of eyes; setae on vertex rather dense but inconspicuous, directed anteriomedially; punctation large in size, scattered rather densely; vertex with longitudinal lack of setae at middle, but narrowly small in size. Eyes: medium in length, occupying approximately half length of head, slightly protruding laterally.
Antennae (Fig. 39): short, moderately shorter than head and pronotum combined; thick, setose, with antennomere IV moderately transverse, but antennomeres V to X strongly transverse in approximately same width each (very slightly but widest around antennomeres VI to VIII); antennomere XI symmetrical, widely rounded at apex; approximate relative length of antennomeres from basal to apex: 18 (including base): 9: 10.5: 4.5: 5: 5: 5: 5: 5: 5: 19.
Pronotum (Fig. 3): oval, rather strongly transverse (PW/PL = 1.42, n = 20), strongly narrowing anterad, moderately longer than sutural length of elytra, widest just below of basal half, basal margin weakly rounded; pubescence dense, directed laterally and posterolaterally; punctation medium and somewhat conspicuous, covered densely and uniformly.
Mesoventrite (Fig. 30): inter coxal process rather broadly elongate, with widely rounded apex, completely reaching to inter coxal process of metaventrite.
Metaventrite (Fig. 30): inter coxal process of metaventrite large, broadly and weakly rounded apically.
Elytra (Fig. 3): together, transverse (EW/EL = 2.02, n = 20), rather small, slightly smaller than pronotum, widest at middle; fine pubescence scattered densely, diverging posteriorly in each elytron; dorsal surface rough and impressed rather strongly and deeply; posterolateral corners of each elytron not sinuate.
Legs (Fig. 3): simple, short, moderately slender; fore and midtibia, densely covered with undeveloped spines, respectively.
Abdomen (Fig. 3): first three visible tergites deeply impressed transversely at base; dorsal and ventral surface moderately covered with thin and long setae.
Male: tergite VIII (Fig. 65): broadly transverse, posterior margin smooth, not serrate at all, insignificantly broadly emarginate medially; dorsal surface very weakly rough, covered densely with setae, with approximately 16 macrosetae. Sternite VIII (Fig. 67): broadly transverse, posterior margin very broadly rounded, with a dense row of minute sensory setae (see Yamamoto & Maruyama, 2012: 10), and with a small complex-cluster of very minute setae just behind the row of minute setae; ventral surface densely covered with setae, with over 20 macrosetae. Median lobe of aedeagus (Figs 69–70): [lateral view (Fig. 69)]: robust, narrowly elongate, subparallel sided, but rather strongly narrowing apically at apical 1/4 of median lobe; apical lobe pointed, not hook- shaped at apex; [parameral view (Fig. 70)]: narrowly elongate, with basal part elliptically shaped; apical lobe abruptly narrowing near apex, forming short isosceles triangle; a series of complex sclerites, restricted to apical 1/3 of median lobe.
Female: tergite VIII (Fig. 66): broadly transverse, posterior margin as in male; dorsal surface covered with setae densely, with approximately 14 macrosetae. Sternite VIII (Fig. 68): posterior margin, shallowly broadly emarginate medially; ventral surface densely covered with setae, with approximately 15 macrosetae; no complexcluster of minute setae situated near posterior margin. Spermatheca (Fig. 71): weakly curved, deformed C-shaped; apical invagination of spermatheca moderately deep; spermathecal head and neck weakly elliptically shaped together; attachment of spermathecal duct conspicuous; basal part of spermathecal stem widely curved, swollen in apical half, moderately longer than spermathecal head and neck combined; chitinized portion of spermathecal stem not strongly developed; each part of spermatheca uniformly and weakly sclerotized; inner wall of spermathecal head and neck densely striate, that of basal part reticulate coarsely.
Distribution. Japan (Hokkaidô, Honshû, Shikoku, Kyûshû; Okushiri-tô Is., Tsu-shima Is.); Russia (Far East, eastern Siberia), Korea, China, Taiwan (new record), Palearctic, Nearctic, Oriental, Afrotropical, and Neotropical regions.
Host records. Two dipteran families are known as its host (Maus et al., 1998): Muscidae, Calliphoridae.
Comments. Aleochara lata is a rather rare species of Aleochara found in mountainous regions of Japan. This Holarctic species has a conspicuously large body. No specimen was found outside mainland Japan except for Okushiri-tô and Tsu-shima Islands (Fig. 123).
