Diagnosis.
Vein 3-SR of fore wing longer than vein 2-SR (
Fig. 5
A),
if
subequal then vein M+CU of hind wing shorter than vein 1-M (
Fig. 5
A); third antennal segment shorter than fourth segment (
Fig. 5
M); vein CU1b of fore wing longer than vein 3-CU1 (
Fig. 5
A); apex of ovipositor sheath nearly always without spine and often blunt (
Fig. 4
B).
Taxonomy.
The large genus
Phaenocarpa
contains some aberrant groups, which for the moment are recognised as subgenera (
Belokobylskij, 1998
). Two former genera are re-instated as subgenus, because their type species possess also aberrant character-states:
Kahlia
Ashmead, 1900 (Nearctic)
, and
Idiolexis
Foerster, 1863 (Palaearctic)
, both because of aberrant venation of the hind wing.
Idiolexis
was synonymized with
Phaenocarpa
by
Szépligeti (1904)
and again by
Wharton (2002)
. The type species has a different hind wing venation (vein M+CU about as long as vein 1-M and vein r faintly developed) and the first subdiscal cell of the fore wing is small.
Kahlia
was also synonymized with
Phaenocarpa
by
Szépligeti (1904)
and usually treated as such (e.g.
Marsh, 1979
;
Braet, 2006
). It was treated as subgenus by
Papp (1967)
but with a different diagnosis (antenna very long and with more than 50 segments) that may not fit the type species (the antenna are broken in the holotype). The type species has vein cu-a of the hind wing absent or largely so, and a short vein M+CU; it is only known from the male holotype and the future discovery of the female may change the status of the subgenus. In this paper we describe a new Oriental subgenus:
Clistalysia
nov.
, because of its highly aberrant morphology of the ovipositor, the different hind wing venation (vein M+CU about as long as vein 1-M) and the widened third antennal segment.
Biology.
Large genus, containing koinobiont endoparasitoids of larvae of cyclorrhaphous
Diptera
in many niches (
Wharton, 1984
).
