Description

Body length: 6.2-7.9 mm, width: 2.6-3.3 mm.

Coloration (Fig. 4 A, B) shiny, black or reddish black, elytra somewhat iridescent; antennae, maxillary palpi, labial palpi, lateral margin of pronotum, and legs yellowish brown; labrum and mandibles dark reddish brown; apex of each mandible black; ventral side overall black, partially brownish.

Head (Fig. 4 C, D) moderately convex, glabrous; eye prominent, distinctly convex; tempora very short and flat; mandible narrowly rounded at apex, not truncate; anterior margin of labrum moderately concave; anterior margin of clypeus slightly emarginate; frontal impression somewhat distinct, gently becoming shallow near eye; supraorbital seta located slightly before the level of hind margin of eye; microsculpture invisible on disc, consisting of faint transverse meshes near hind margin of eye and somewhat isodiametric meshes near supraorbital seta; postgena not ciliate; mentum and submentum fully separated by transverse suture; mentum with one distinct tooth, which is rounded at apex, epilobe slightly widened anteriorly, minutely projected beyond lateral lobe; submentum with a long seta on each side; ligula narrow on base, gently widened apically, apex truncate, with two apical setae; paraglossa somewhat narrow, separated from ligula by a quite wide notch; penultimate maxillary palpomere distinctly shorter than apical palpomere; penultimate labial palpomere slightly shorter than apical palpomere; antenna extending behind basal margin of pronotum.

Pronotum (Fig. 4 C) moderately convex anteriorly, somewhat flat posteriorly, wider than long, widest slightly behind 1/3 from apex, PbW longer than PL; apical margin slightly or moderately emarginate, clearly bordered laterally, but faintly or not bordered in middle; apical angle rounded, protruding anteriorly; lateral margin without sinuation, almost linear posteriorly; lateral seta located slightly before widest point; basal margin almost straight, weakly bisinuate, slightly longer than apical margin, completely bordered, slightly interrupted in middle; basal angle distinctly obtuse, narrowly rounded, not protruding laterally; disc glabrous; median line clear, interrupted near base, not reaching apical border and reaching or not reaching basal border; anterior impression very faint; basal fovea shallow or slightly deep, gently curved outwards; basal area sparsely punctate in lateral and median area, rather distinctly punctate in basal fovea; lateral area sparsely punctate from base to the point near lateral seta and somewhat smooth or faintly punctate anteriorly; apical area rather variable in punctation, usually with a few faint punctures along apical margin, sometimes with more distinct punctures medially; microsculpture consisting of faint transverse meshes on disc. PW/HW = 1.37-1.44, mean 1.40; PW/PL = 1.44-1.55, mean 1.49; PW/PbW = 1.23-1.32, mean 1.27, in nine males and six females.

Elytra slightly convex, widest a little before middle; basal edge slightly curved, almost linear, forming an obtuse angle with lateral margin; humerus with minute acute tooth visible from behind; apical sinuation very weak; intervals overall flat, slightly convex near apex, without punctation; setigerous pore of interval 3 located near 3/5 from base; striae moderately deep; parascutellar striole moderately long, rarely reaching stria 1; marginal umbilicate series with 7-9 pores (usually 8 pores) in anterior group and 8-11 pores (usually 9-10 pores) in posterior group; microsculpture invisible on disc. Hind wing fully developed. EW/PW = 1.23-1.32, mean 1.27; EL/EW = 1.45-1.53, mean 1.49, in nine males and six females.

Ventral side (Fig. 4 B, E) moderately convex; prosternum covered with very short and fine pubescence; median area of metasternum, median area of abdominal sternite III, and anteromedian area of IV more sparsely pubescence than prosternum; proepisternum sparsely and faintly punctate; meso-, metepisternum, and lateral area of metasternum sparsely punctate; metepisternum (Fig. 4 E) distinctly longer than wide (ML/MW = 1.33-1.45, mean 1.38, in eight males and five females), anterior and inner margin bordered; apical margin of abdominal sternite VII widely rounded in male and somewhat narrowly rounded in female, with two pairs of setae in both sexes.

Legs. Protibia not longitudinally sulcate on dorsal side; metacoxa with two setae; metafemur with two setae in hind margin; metatarsus shorter than width of head (metatarsus/HW = 0.73-0.82, mean 0.78, in eight males and six females); metatarsomere 1 shorter than metatarsomere 2 and 3 combined, about 1.5 times longer than metatarsomere 2, as long as metatarsomere 5, but generally metatarsomere 5 slightly longer; tarsomere 5 usually with three setae, sometimes two setae in each ventrolateral margin.

Male genitalia (Fig. 5 A-I). Median lobe of aedeagus (Fig. 5 A-F) slender, moderately curved behind basal bulb and slightly curved before apex in lateral view, almost linear in dorsal view; terminal lamella slightly wider than long, gently contracted towards apex; apex somewhat narrowly rounded; internal sac covering right lateromedian part consisting of numerous round patches (Fig. 5 F); internal sac without sclerotized part, but sometimes with a very small sclerotized piece; ventral side of median lobe bordered, rudimentarily serrate in middle; parameres as in Fig. 5 G, H; sternite IX (Fig. 5 I) explanate on basal area.

Female genitalia (Fig. 5 J). Hemisternite with two spines apically; basal stylomere with one to three (usually two) preapical spines on external margin; apical stylomere slender, with two setae subapically, inner margin almost straight, slightly curved, outer margin gently curved, dorsal and ventral outer margin with one small distinct spine, respectively.

Diagnosis

The description of the Trichotichnus congruus -group by Habu (1973) well matches with this species, except for the basal angle of the pronotum not being angulated. This species can be distinguished from others by pronotum with rounded basal angle, apical margin of abdominal sternite Ⅶ with two pairs of setae in both sexes, protibia not longitudinally sulcate on dorsal side, metatarsus shorter than width of head, and conformation of internal sac of aedeagus in right lateral view.

Distribution

Korea: South (new record), North ( Kataev and Wrase 2017); China: Guizhou, Hubei, Hunan, Sichuan, Shaanxi, Zhejiang ( Kataev and Wrase 2017).

Ecology

The immature adults were observed from June to July, whereas the mature adults were observed from late March to early May. Most individuals were observed under the leaf litter at the bottom of the drainage channel, located in the surroundings of the deciduous forest (Fig. 3 A, B).

Notes

This species was first recorded in Korea by Kataev and Wrase (2017), based on the specimen from the northern part of Korea, and is recorded for the first time for the southern part of Korea by the current study. The specimens from the southern island of Geojedo Island (Naedo Island) might indicate the possibility of the occurrence of this species in Japan.
