Holotype labels.

Mic./760. Second label: VN: Yên Bái, Luc/ Yên, Phúc Lợi./Rứng TS 07-X-2003/KH. Ɖ. LONG. Third label: CNC878543. There is a fourth, red label associated with the holotype specimen. Apparently it was attached as the specimen was considered to be a potential paratype of a Choeras species never described. We are not detailing that name here as it is not valid, and the specimen does not belong to Choeras , but we are just noting the existence of that fourth label -which we did not remove because the specimen belongs to a different institution than ours.

Diagnosis.

This is the only known species in the genus so far, thus the generic diagnosis works as the species diagnosis as well.

Description.

Female. Body color mostly yellow, except for dark brown to black head and T5-7 sometimes with brown marks centrally. Antenna yellow to light brown-yellow. Legs yellow except for dark brown spot on anterior 0.1 of metatibia, and brown metatarsus. Wings veins mostly brown, except for yellow-white vein R1 on fore wing and pterostigma with yellow-white spot on anterior 0.3. Face with slightly coarse punctures. Mesosoma mostly smooth, at most with areas with sparse and shallow punctures. Polished area of lateral face of scutellum (lunules) relatively very small, less than 0.2 height of lateral face. Propodeum carination pattern that includes three complete longitudinal carinae (one medially, the other two sublaterally) and a complete transverse carina (subapically), with additional small striae radiating from the median and sublateral carinae (Fig. 27D, F ); most carinae are strongly defined and raised. Fore wing with relatively large and quadrate areolet. Hind wing with vannal lobe entirely setose. Metatibia with relatively strong spines (peg-like) on dorsal surface, which are darker than metatibia color. Metasomal terga smooth. T1 rectangular, T2 trapezoidal. Hypopygium inflexible, without pleats. Ovipositor sheaths setose and less than half the length of the metatibia. Body measurements (mm). F2 L: 0.24 (0.25-0.26); F3 L: 0.23 (0.25-0.26); F14 L: 0.13 (0.14-0.17); F15 L: 0.12 (0.11-0.13); Malar sulcus L: 0.06 (0.07); Mandible W: 0.10 (0.09); T1 L: 0.44 (0.43-0.48); T1 W at posterior margin: 0.19 (0.21); T1 maximum W: 0.27 (0.27); T2 W at anterior margin: 0.20 (0.18-0.20); T2 W at posterior margin: 0.38 (0.35-0.36); T2 L: 0.16 (0.14-0.16); Metafemur L: 0.76 (0.80-0.83); Metafemur W: 0.25 (0.26-0.28); Metatibia L: 1.03 (1.03-1.07); Inner spur L: 0.23 (0.26-0.28); Outer spur L: 0.14 (0.18); First segment of Metatarsus L: 0.45 (0.48-0.50); Ovipositor sheaths L: 0.46 (0.50-0.53); Body L: 3.06 (2.45-3.03); Fore wing L: 3.06 (3.19-3.28). T2 W at posterior margin is approximate for 1 specimen.

Biology.

Host unknown.

Distribution.

Bangladesh, Malaysia, Taiwan, Thailand, Vietnam.

Molecular data.

Three paratypes with available sequences belong to BIN BOLD:AAV2185, which is 6.7 % different from the closest Microgastrinae sequence in BOLD (another putative, undescribed species of Kotenkosius , but we have not been able to see specimens from that BIN).

Etymology.

From Latin “trēs” (meaning “three”) and “carina” (meaning “keel”), referring to the three longitudinal carinae found on the propodeum.

Comments.

The record of this species from Bangladesh is based on a sequence recorded in BOLD which matches the sequences of the paratypes; however, we have not seen that specimen and thus cannot confirm unequivocally its identity. A second species of Kotenkosius seems to be revealed in BOLD (BIN BOLD:ADB2437), based on how similar the sequences are; however, we have not seen specimens from that BIN and thus cannot conclude on that.
