(
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).

Diagnosis
: This species is similar to

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.

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.
