Diagnosis
Pholetesor acrocercophagus
sp. nov.
is closely related to
P. circumscriptus
(Ness, 1834)
in the European keys to the species of the ʻ
circumscriptus
-groupʼ (
Nixon 1973
;
Papp 1983
) on the basis of the following characters: thorax in profile less elongate; metanotum strongly retracted from scutellum anteriorly, exposing mesothoracic postphragma; pterostigma almost 3.0× as wide as long; vein 1-R1 (metacarp) clearly longer than pterostigma, r and 2-SR slightly curved, meeting less angularly; propodeum largely smooth; hind femur yellowish; T1 largely smooth, polished and strongly narrowed apically; T2 +3 smooth and polished. However, it differs from
P. circumscriptus
in the following characters: T2 subtriangular 2.0× as wide as long posteriorly, hence more transverse (T2 strongly triangular 2.6× as wide as long posteriorly in
P. circumscriptus
); scutellar sulcus narrow with fine foveation (scutellar sulcus narrow with fine groove in which there is no obvious foveation in
P. circumscriptus
); forewing vein r arising medially of the pterostigma (forewing vein r arising distally of the pterostigma in
P. circumscriptus
); F2 2.5 × as long as wide (F2 3.6 × as long as wide in
P. circumscriptus
); body comparatively small, about
1.5 mm
(body larger, about 1.80–2.00 mm in
P. circumscriptus
).
Etymology
The new species is named after its host insect.

Almost 2 × as wide as long; eyes 1.6× as long as temple in dorsal view; temple and vertex smooth, shiny, punctate with hairs; eyes setose, 1.4 × as long as wide, OOL: POL: AOL: OD = 4: 3: 2: 2; frons concave, smooth and shiny, face medially convex, punctate with hairs; clypeus 3× as wide as long, flattened, indistinctly punctate; malar space about as long as basal width of mandible; antennae about as long as body; scape 1.5× as long as wide, pedicel slightly wider than long, F1 3.0× as long as wide, F2 2.5× as long as wide, flagellomeres gradually decreasing apically, apical flagellomere longer than F15 and pointed.
MESOSOMA. About as long as wide and 1.5× its height; mesoscutum distinctly punctate with hairs, punctations becomes obscured posteriorly, scutellar sulcus narrow with fine foveation; scutellum smooth and shiny, side of scutellum smooth and shiny; propodeum about 2.0 × as wide as long at longest point, largely smooth; posteriorly with series of ridges extending obliquely on either side from nucha; propleuron smooth and shiny; mesopleuron antero-dorsally smooth and shiny, postero-laterally punctate with hairs.

Remarks
Pholetesor acrocercophagus
sp. nov.
can be distinguished from all previously described species by the unique combination of characters as follows: metanotum strongly retracted from scutellum anteriorly, exposing mesothoracic postphragma; propodeum about 2.0× as wide as long at longest point, largely smooth; posteriorly with a series of ridges extending obliquely on either side from nucha; T1 about 3.0× as long as its apical width, 1.8 × its basal width, strongly narrowed apically, smooth and shiny except few punctures; T2 2.0× as wide as long, subtriangular, smooth, shiny, shorter than T3; T3 rectangular, 1.40× as long as T2, unsculptured; hypopygium weakly sclerotized, transparent, medially folded, blunt at apex, 2.0× as long as hind basitarsus; ovipositor sheaths elongate-fusiform, thick and hairy throughout their length, arising about half of valvifer; ovipositor pointed at apex and curved downwards.
