Figs 7 View Figure 7 , 9A, C, E View Figure 9
Type material
(N = 1, 1 ♂). Holotype male. "Korea: Gangwon Prov. Bangdong-ri, Girin-myeon, Inje-gun, 23 Jun 2009, sifting flood debris, T.-K. Kim, CNUIC" (NIBR).
Diagnosis.
Antennal pedicels less enlarged subglobose, with dorsolateral glandular nodule on subapical (Fig. 7C, D View Figure 7 , arrows); protibiae with spine on internal side at widest point (Figs 7E View Figure 7 , 9C View Figure 9 , arrows); parameres of male genitalia with depression on lateral margin and three setae on apical (Fig. 7G View Figure 7 ).
Description.
Body reddish brown, antennae, maxillary palpi, and tarsi slightly lighter, length 1.62 mm, maximum width 0.70 mm (Fig. 7A, B View Figure 7 ). Setae on body yellowish, long and dense. Head long as wide (Fig. 7C View Figure 7 ). Frons with U-shaped impression between antennal tubercles; frontal foveae absent; frontal rostrum distinct anteriorly. Vertex slightly convex; longitudinal carina present; vertexal foveae small. Eyes large with 34 facets. Maxillary palpi moderately developed; palpomeres II-III with dense tubercles; palpomere IV 0.25 mm long and about 3.30 times as long as wide, subcylindrical pseudosegment at apex. Antennae about 0.54 mm long; scapes subcylindrical, without modification, 1.83 times as long as pedicels; pedicels long as wide; antennomere III 1.70 times as long as wide; IV-VIII subequal in length; IX 0.89 times as long as wide; X 0.78 times as long as wide; XI largest, pointed at apex, 1.86 times as long as wide (Fig. 7D View Figure 7 ). Pronotum 0.79 times as long as wide and widest at basal 3/5, lateral antebasal foveae connected by antebasal sulcus. Elytra slightly convex, 0.98 times as long as wide and widest at basal 1/3, each elytron with two basal foveae and subhumeral fovea. Legs robust; metatibiae with spine at apex (Fig. 7E View Figure 7 , arrow). Aedeagus large, 0.36 mm long and 2.05 times as long as wide; penis fusiform and dorsal diaphragm transversely ovoid; parameres short and symmetrical, apices truncated; endophallus composed of two fine struts, asymmetrical (Fig. 7G View Figure 7 ).
Sexual dimorphism. Unknown.
Remarks.
The adult of this species is similar to Bryaxis nemorosus Choi, Park, Lee & Park sp. nov. in the shape of antennomeres IV-XI (Figs 7D View Figure 7 , 8F View Figure 8 ). However, it can be distinguished by the robust setae on the body (Fig. 7A View Figure 7 ), large eyes as long as the tempora (Fig. 9E View Figure 9 ), a strongly tuberculate maxillary palpomere II (Fig. 9A View Figure 9 ), protibiae with a spine at the widest point (Fig. 9C View Figure 9 , arrow), and a simple endophallus of the male genitalia (Fig. 7G View Figure 7 ).
Etymology.
This species is named after the type locality, Girin-myeon, Inje-gun.
Habitat.
The holotype was collected by sifting flood debris in mixed forest.
Distribution.
Korea (Inje-gun, Gangwon-do).
