Head shiny, smooth, densely punctate, unsculptured among punctures; clypeus and anterior part of face densely hairy; frontal line incomplete, only visible in front of anterior ocellus; occipital carina complete; head of holotype with POL = 2; OL = 1.5; OOL = 4; OPL = 2.8; TL = 4.4; greatest diameter of posterior ocelli shorter than OPL (1.2:2.8); head of specimen from China, Dashahe, with POL = 5; OL = 3; OOL = 7.5; OPL = 4; TL = 6; greatest diameter of posterior ocelli shorter than OPL (2:4). Pronotum shiny, densely punctate, crossed by transverse impression, with anterior suface shorter than posterior one (2:4); pronotal tubercle reaching tegula; in specimen from China, Dashahe, posterior surface of pronotum much shorter than scutum (5:16). Scutum and scutellum shiny, punctate, unsculptured among punctures; notauli incomplete, reaching approximately 0.5 length of scutum. Metanotum reticulate rugose. Propodeum reticulate rugose, without transverse or longitudinal keels. Fore wing hyaline, without dark transverse bands. Distal part of stigmal vein of holotype approximately as long as proximal part (6.5:6); distal part of stigmal vein of specimen from China, Dashahe, shorter than proximal part (7:10). Stigmal vein forming angle between distal and proximal part. Protarsal segments of the holotype in following proportions: 5.2:1.5:1.7:4:10.5; protarsal segments of specimen from China, Dashahe, in following proportions: 15:4:5:12:30. Enlarged claw (Plate 58A) with proximal prominence bearing one long bristle. Segment 5 of protarsus (Plate 58A) with basal part shorter than distal part (4.5:6), with preapical furrow containing distal apex of enlarged claw when the chela is closed. Holotype with segment 5 of protarsus with two rows of 29 lamellae (4 + 25); distal apex with five lamellae. In specimen from China, Dashahe, segment 5 of protarsus with three rows of at least 50 lamellae; distal apex with five lamellae. Tibial spurs 1/1/2.
Description of Male. Fully winged; length 2.9–3.6 mm. Head black; antenna black-brown; mesosoma and metasoma black; legs black-brown. Antenna filiform; antennal segments in following proportions: 11.5:6.5:13:13:12.5:12.5:11:10:10:12. Head hairy, shiny, finely punctate, unsculptured among punctures; frontal line incomplete, reaching approximately 0.5 length of face; occipital carina complete; POL = 6; OL = 2.5; OOL = 9; OPL = 4; TL = 6. Scutum, scutellum and metanotum shiny, smooth, finely punctate, unsculptured among punctures. Notauli incomplete, reaching approximately 0.5 length of scutum. Propodeum dull, without transverse keel between dorsal and posterior surface; dorsal surface reticulate rugose; posterior surface with two longitudinal keels and with median area as rugose as lateral areas. Fore wing hyaline, without dark transverse bands; holotype of L. niger and many further specimens with darkened fore wing. Distal part of stigmal vein approximately as long as proximal part (10:11); stigmal vein forming angle between distal and proximal part. Paramere (Plate 58B) without distal inner process and with papillae on inner side. Tibial spurs 1/1/2.

Remarks. Lonchodryinus niger He & Xu, 2002 is here tentatively considered the opposite sex of L. bimaculatus Xu & He, 1994, and, for this reason, synonymized. The sculpture of head and mesosoma of both species is in fact in great part very similar. In addition, only four species of Lonchodryinus are known in China: L. sinensis and L. ruficornis, whose opposite sexes are known, and L. bimaculatus and L. niger, respectively known on the basis of females and males. The association of the male of L. niger with the female of L. bimaculatus is very probable.
