Type material examined.

Holotype: Korea • 1 ♂ (slide no. NIBRIN 0000992641 ) Gangwon-do, Pyeongchang-gun, Jinbu-myeon, Odaesan-ro, Mt. Odae, the road before temple (Buk-Dae-Mi-Reuk-Am) (Odae 2); 11–26 May 2019; D. Ham, S. Park leg.; deposited in NIBR . Paratype: Korea • 1 ♂ (slide no. NIBRIN 0000919408 ); same data and deposition as holotype .

Diagnosis.

Campylomyza odae sp. nov. is distinguishable from other Campylomyza species by the following combination of characteristics: 1) Apical margin of gonostyli rounded (Fig. 5 A , ↓ 3); 2) Dorsal processes on tegmen with inconspicuous pair of subtriangular processes anterolaterally; 3) Dorsal processes constricted medially, forming mesal cleft (Fig. 5 C , ↓ 6); 4) Cerci visible (Fig. 5 D ).

Measurements.

Male adult (Holotype): Body length 1.737 mm. Wing length 1.870 mm. Hind leg coxa 0.221 mm; femur 0.713 mm; tibia 0.624 mm; tarsomere I 0.369 mm; tarsomere II 0.193 mm; tarsomere III 0.134 mm; tarsomere IV 0.089 mm; tarsomere V 0.072 mm.

Description.

Male adult. Slightly larger than other Campylomyza species. Head. Postocular bristles four. Antenna with 12 flagellomeres. Neck of fourth antennal flagellomere slightly shorter than node. Node with one complete and two incomplete crenulate whorls with sensory hairs, two incompletely collar-shaped sensilla distally. Palpus 4 - segmented; fourth segment longest. Thorax. Wing length to width ratio 2.39, AntC ending beyond R 4 + 5 but before reaching M 4; ApicR 1 4.31 × length of Rs; CuA separated. Tarsomere I longer than tarsomere II. Claws sickle-shaped, toothed; empodia small, shorter than claws. Terminalia. Tg 9 broadly tapered towards apex with eight fine setae. Ventral emargiantion U-shaped; ventral bridge long; dorsal transverse bridge extending far beyond ventrobasal margin (Fig. 5 A , ↓ 1); ventromedial portion of gonocoxites relatively narrow, not pronounced (Fig. 5 A , ↓ 2). Gonostyli short, stout, strongly convex posteriorly, truncated apically (Fig. 5 A , ↓ 3), directed ventrally, bearing dorsoapically numerous straight setae of various length, with denser stiff setae as it goes to apex. Tegmen narrow, shoulders inconspicuous. Parameral apodemes short. Apical points lamellated, triangular-shaped, directed posteriorly (Fig. 5 C , ↓ 4), separated by wide cleft mesally; dorsal processes subtriangular shaped, directed dorsomedially, apices crossed with spreading subtriangular extensions (Fig. 5 C , ↓ 5); each dorsal process constricted at midlength, forming mesal cleft (Fig. 5 C , ↓ 6). Cerci visible.

Etymology.

The species name odae is a noun in apposition to the collection locality, Mt. Odae in Gangwon province.
