Lu, Qian-Yu, Chai, Hong-Fei, Achterberg, Cornelis Van, Tang, Pu & Chen, Xue-Xin, 2025, The first review of the subgenus Ganychorus Haliday, 1835 (Hymenoptera, Braconidae, Brachistinae) in China, Zootaxa 5575 (2), pp. 201-250 : 211

Blacus (Ganychorus) comatoides sp. nov.

( Figs 7–8 )

Material examined. Holotype: ♀, China, Yunnan, Bao Mtn, Lujiangba, Gaoligongshan Nature Park , 10.V.2009, Wang Manman, No. 200904523 ( ZJUH).

Diagnosis. The new species is similar to B. (G.) comatus van Achterberg, 1988 because it shares ♀ -antenna with 22 antennomeres, long and densely setose, several basal antennomeres yellow, subapical antennomers pale yellow, first discal cell truncate anteriorly, precoxal sulcus crenulate medially, frons glabrous, metasoma (except first tergite) largely brown, antenna slender submedially, fore claws with blackish bristles, and first metasomal tergite nearly parallel-sided, but differs by having narrow notauli (wide in B. (G.) comatus ), length of first metasomal tergite 3.3 × its apical width (2.3 ×), only apical one antennomere brown (except for 5 basal antennomeres, remaining antennomeres dark brown), hind coxa with a rugose carina (with some rugae dorsally), propodeal tubercles small (absent), and base of hind tibia yellow (narrowly dark brown).

Description. Female. Length of body 2.7 mm, length of fore wing 2.65 mm.

Head. Antennomeres 22, long and densely setose ( Fig. 8C ); length of first flagellomere 1.6 × length of second flagellomere; length of first, second and penultimate flagellomere 6.6, 4.0 and 1.9 × their width, respectively; length of maxillary palp 1.05 × height of head; occipital carina complete; frons smooth and glabrous, frontal suture present; OOL: OD: POL = 8: 5: 4; length of eye in dorsal view 1.9 × length of temple; face smooth; malar suture present, length of malar space 1.25 × basal width of mandible.

Mesosoma. Length of mesosoma 1.4 × its height; side of pronotum rugose ventrally and smooth dorsally; precoxal sulcus sparsely crenulate medially ( Fig. 8E ); notauli narrow, deep and finely crenulate ( Fig. 8D ); mesoscutal lobes densely setose; scutellum rugose, strongly protruding dorsally; propodeal tubercles small; surface of propodeum largely smooth between carinae, medial area present, long and parallelsided ( Fig. 8F ).

Wings. Fore wing: first discal cell widely truncate anteriorly; 1-CU1: 2-CU1 = 4: 11 ( Fig. 8I ).

Legs. Hind coxa with an oblique carina dorsally; length of femur, tibia and basitarsus of hind leg 6.8, 12.8 and 11.3 × their width, respectively; fore claws with blackish bristles; middle ( Fig. 8K ) and hind claws simple.

Metasoma. Length of first tergite 3.3 × its apical width, parallel-sided, spaced rugose ( Fig. 8G ); second tergite smooth ( Fig. 8G ); length of ovipositor sheath 0.11 × length of fore wing; metasoma long setose.

Colour. Blackish; basal half of antenna, palpi and all legs yellow; subapical antennomeres pale yellow; apical antennomere, mandible, apical half of metasoma, tegulae, pterostigma, parastigma, veins, ovipositor and its sheath brown; wing membrane subhyaline.

Male. Unknown.

Biology. Unknown.

Distribution. China (Yunnan).

Etymology. The specific name refers to the similarity of this species with B. (G.) comatus ; “- oides ” is Latin for likeness.
