Head. Slightly elongate, approximately 1.1 times as long as wide, widest behind eyes, slightly narrower than pronotum; eyes small and slightly prominent, about 0.8 – 1.0 times as long as temples; gular sutures moderately separated, diverged basally; infraorbital carina absent; cervical carina complete.

Mouthparts. Labrum ( Figure 2 View Figure 2 (a)) transverse, emarginate in anterior margin, with Ε- sensillum and eight macrosetae on each side of midline; epipharynx ( Figure 2 View Figure 2 (b)) with several sensilla, including two lateral sensory rows on each side of midline; β- and γ- sensilla very short, blunt at apex. Mandibles ( Figure 2 View Figure 2 (c,d)) about 1.7 times as long as basal width; right one ( Figure 2 View Figure 2 (c)) with internal tooth, internal margin slightly serrulate; prostheca composed of three portions. Galea and lacinia of maxilla ( Figure 2 View Figure 2 (e)) long and slender; lacinia composed of nine spines in distal comb region, isolated spines absent; maxillary palpomere 1 smallest and about 1.8 – 2.0 times as long as wide, 2 about 2.6 – 2.7 times as long as wide, 3 slightly longer than 2, about 2.4 – 2.5 times as long as wide, 4 digitiform, filamentous sensilla reaching to basal half. Prementum ( Figure 2 View Figure 2 (f)) with two basal pores moderately separated, about 3.0 – 4.0 times width of basal pore; medial pseudopores, one setal pore and three or four real pores present on each side of midline; labial palpomere 1 largest, about 1.7 – 1.8 times as long as wide, with γ- setula close to b-seta, 2 shortest, about 1.3 – 1.5 times as long as wide, 3 parallel-sided and about as long as 1, about 3.5 – 4.0 times as long as wide. Mentum ( Figure 2 View Figure 2 (f)) trapezoidal, anterior margin emarginate; v-seta short. Thorax. Pronotum ( Figure 3 View Figure 3 (b)) subquadrate, approximately 1.1 times as wide as long, widest in apical fourth, narrow apically, pubescence directed anteriorly in midline; hypomera fully visible in lateral aspect. Metanotal scutum with one long seta and about two to four short setae on each side of midline. Mesocoxal cavities narrowly separated; mesoventral process distinctly pointed at apex, longer than metaventral process; isthmus longer than metaventral process; length ratio of mesoventral process, isthmus and metaventral process 7: 6: 2. Elytra slightly wider than pronotum; elytron approximately 1.6 – 1.7 times as long as wide, postero-lateral margin almost straight; pubescence directed posteriorly and postero-laterally; hind wings fully developed, flabellum composed of about five or six setose lobes. Legs. Slender and long, with pubescence and macrosetae; tibiae with different length of two spurs at apex; tarsal formula 4-5-5, length ratio of tarsomeres 20: 23: 25: 50 (protarsus); 28: 30: 30: 26: 45 (mesotarsus); 47: 36: 35: 32: 51 (metatarsus). Abdomen. Parallel-sided; surface glossy and densely pubescent, with transversely imbricate microsculpture; macrochaetal arrangement of tergites II – VI 01-12-12-12-13; male tergite VII ( Figure 3 View Figure 3 (c)) without tubercles; male tergite VIII with four macrosetae on each side of midline, posterior margin ( Figure 3 View Figure 3 (d)) subtruncate; male sternite VIII with seven macrosetae on each side of midline, posterior margin subtriangularly convex, with marginal setae; posterior margin of female tergite VIII subtruncate; female sternite VIII with six macrosetae on each side of midline, posterior margin round, with long marginal setae, minute setae present in median region. Aedeagus. Median lobe ( Figure 3 View Figure 3 (e,f)) narrowly ovate, narrow and convergent apically in ventral aspect; apical process slightly bent in lateral aspect. Apical lobe of paramerites ( Figure 3 View Figure 3 (g)) with four setae; a-seta longest, the other setae short and subequal in length, c- and d-setae positioned apically. Spermatheca. Bursa elongate, with conical-shaped umbilicus; duct short and simple, dilated and round apically ( Figure 3 View Figure 3 (h)).

Distribution

Korea (South).

Remarks

This species is similar to A. parviocularis sp. nov., but can be distinguished by the characters provided in the key and different shape and structure of the aedeagus and spermatheca. Almost all specimens have been collected near stream with other Aloconota species.

Etymology

Named derived from the Latin brunnea meaning ‘ brown ’, which refers to the body colour.
