description: Coeloides guizhouensis Yang, 1996 (Figs. 18–20)
Coeloides guizhouensis Yang, 1996, Parasitic wasps on bark beetles in China, 22.
Material studied. 4ΨΨ 3ɗɗ, CHINA, Guizhou, Guiyang city, Eight kilometors City, wood factory, 13. viii. 1981, Yang Zhong­qi, ex. Ips duplicatus Sahlberg (holotype and paratypes, CAFB).
Diagnosis: This species is similar to Coeloides melanotus Wesmael, but can be separated from the latter by having the third flagellomere flared apically, first metasomal tergite with wide and smooth grooves laterally, shallow anteriorly and deep posteriorly, and second metasomal tergite with narrow and deep longitudinal grooves laterally. It has antennae with 47–50 segments, first flagellomere slightly longer than the second one; second flagellomere strongly flared apically; third flagellomere flared apically, 1.2 times as long as the second one notauli of mesoscutum entirely deep and wide, not flatted posteriorly; 2­SR: SR1 = 1: 3.0; first metasomal tergite with wide and smooth grooves laterally, shallow anteriorly and deep posteriorly; second metasomal tergite with narrow and deep longitudinal grooves laterally; and ovipositor sheath relatively long, 1.5 times as long as abdomen.
Biology: The known hosts are the larvae of Ips duplicatus Sahlberg of the family Scolytidae (Coleoptera) (Yang, 1996).
Distribution: China (Guizhou province).
Coeloides hummeli Fahringer, 1934
Coeloides hummeli Fahringer, 1934: Opusc. Bracon. 3 (5–6): 327.
Diagnosis: This species is similar to C. melanotus Wesmael, but can be distinguished from the latter by the metasomal tergites with striate sculpture. It has head cubic; antennae shorter than body; first­third flagellomeres apically flared ventro­laterally; frons distinctly impressed behind antennal sockets, with a deep longitudinal groove medially; face smooth medially except for weak rugae laterally; temple strongly round and relatively wide; vertex and temple glabrous and hardly setose; mesosoma smooth and shiny; notauli flatted and hardly impressed; second submarginal cell of fore wing longer than third submarginal cell; cu­a vein of fore wing interstitial; first metasomal tergite glabrous except for fine striae medially; second metasomal tergite with wide longitudinal groove laterally; suture between second and third metasomal tergites deep and smooth; and ovipositor sheath 1.5 times as long as the body.
Biology: Unknown.
Distribution: China (Gansu province) (Fahringer, 1934).
Note: According to Shenefelt (1978) and Yu et al. (2005) the type has been lost and we could not find any specimens that fit Fahringer's original description of the taxon. It is included in the key and the diagnosis provided above according to Fahringer's original description.
