Coeliniaspis Fischer, 2010

Coeliniaspis Fischer, 2010: 646. Type species (by original designation): Coeliniaspis kohkongensis Fischer, 2010 (examined).

Diagnosis.

Flagellomeres of antenna densely setose; clypeus flattened, with ventral lamella or more or less depressed medially and sublaterally protruding (Fig. 7; see arrow); mandible with four teeth, additional (= fourth) tooth dorso-basally on middle tooth (Fig. 10); vein r of fore wing arising from or before middle of pterostigma (Fig. 1); second metasomal tergite coarsely sclerotized, distinctly sculptured and with complete sharp lateral crease.

Remarks.

Coeliniaspis is included in the Coelinius genus-group because of the presence of the longitudinal sculpture on the second metasomal tergite, similar to that of the first tergite, the mandible with an additional tooth between first and second teeth, the metapleuron with rugose sculpture and sparsely pubescent, and the first subdiscal cell of fore wing elongate (Fig. 1). For the differences within the Coelinius genus-group, see the key below.

Distribution.

Oriental (Cambodia, China (new record)), Russia (Far East, new record).

Key to the genera of Coelinius genus-group

(modified after van Achterberg, 2014)

1	Dorsope absent or nearly so; mesosternum with triangular reticulate-rugose area medio-posteriorly; first metasomal tergite more than 2.3 times as long as its apical width; vein 2-R1 of fore wing frequently rather long [pterostigma usually about as long as vein 1-R1; clypeus strongly protruding forwards]	2
-	Dorsope present; mesosternum with only a narrow crenulate suture medio-posteriorly; first tergite usually less than 2.3 times as long as its apical width; vein 2-R1 of fore wing short or absent	3
2	Vein 1-SR+M of fore wing absent; scutellar sulcus chevron-shaped; pterostigma distinctly longer than vein 1-R1 (= metacarp); clypeus moderately protruding forwards	Neocoelinius Granger, 1949
-	Vein 1-SR+M of fore wing present; scutellar sulcus transverse; pterostigma usually about as long as vein 1-R1; clypeus strongly protruding forwards [fourth metasomal tergite smooth; second tergite not carapace-like and second tergite without complete sharp lateral crease; clypeus without pair of ventral protuberances]	Coelinidea Viereck, 1913
3	Dorso-posterior half of pronotal side distinctly protruding posteriorly; metasoma of female blade-like compressed posteriorly; head nearly square in dorsal view; vein r of fore wing issued distinctly behind middle of pterostigma	4
-	Dorso-posterior half of pronotal side truncate, at most dorso-apically protruding; metasoma of female less compressed; head transverse in dorsal view; vein r of fore wing usually issued between base and middle of pterostigma or from its middle	5
4.	Vein r of fore wing strongly oblique; first metasomal tergite elongate; entire dorsal half of pronotal side protruding posteriorly	Coelinius Nees, 1818
-	Vein r of fore wing subvertical; first tergite short; dorsal half of pronotal side less protruding posteriorly [face short, sharp-angularly protruding]	Eucoelinidea Tobias, 1979
5	Clypeus medio-ventrally depressed (arrow in Fig. 7) and sublaterally protruding or emarginate medio-ventrally and with a pair of small ventral lobes [head cubical (Fig. 8); second metasomal tergite with complete sharp lateral crease (Fig. 5) and third tergite evenly setose]	Coeliniaspis Fischer, 2010
-	Clypeus medio-ventrally straight or weakly convex and no ventral protuberances or lamella; sharp lateral crease of second tergite variable, e.g. complete in most Sarops spp.	6
6	Third to sixth metasomal tergites densely setose; tarsal claws lamelliform, widened apically in dorsal view; third tergite usually partly or largely sculptured [vein r of fore wing issued near middle of pterostigma; parasitoid of Lipara spp. in Phragmites -galls]	Polemochartus Schulz, 1911
-	Third to sixth tergites sparsely setose; tarsal claws normal, cylindrical apically in dorsal view; third tergite smooth	7
7	Ventro-lateral corners of clypeus angled; vein r of fore wing issued subbasally from pterostigma; first tergite widened apically; clypeus distinctly protruding in lateral view	Laotris Nixon, 1943
-	Ventro-lateral corners of clypeus rounded; vein r of fore wing issued medially from pterostigma; first tergite subparallel-sided apically; clypeus slightly protruding in lateral view	Sarops Nixon, 1942

1	First metasomal tergite 4.9-5.0 times as long as wide apically and about 4.0 times as long as its maximum width (Fig. 4); apical half of second tergite gradually narrowed posteriorly and 6.0 times longer than its apical width (Fig. 6); third tergite smooth; apical half of notauli widely crenulate and connected to medio-posterior depression of mesoscutum (Fig. 3); vertex and frons distinctly remotely punctate (Fig. 8)	C. insularis (Tobias, 1998) comb. n.
-	First tergite 1.8-2.5 times as long as wide apically and about twice longer than its maximum width; second tergite parallel-sided and 1.5 times longer than its apical width; third tergite more or less sculptured; notauli developed on anterior half of mesoscutum and absent near medio-posterior depression; vertex and frons finely punctulate [clypeus distinctly emarginate medio-ventrally, resulting in a pair of small ventral lobes]	2
2	Posterior half of notauli present, crenulate and nearly reaching scutellar sulcus; in dorsal view, temple and eye almost equal in length; head in dorsal view 1.5 times wider than long medially; antenna, hind coxa and femur, and apical half of metasoma brownish yellow	C. rufiventris (Tobias, 1998) comb. n.
-	Posterior half of notauli absent, remaining far from scutellar sulcus; temple in dorsal view 1.4 times as long as eye; head in dorsal view 1.2 times wider than long medially; antenna black (except for yellow scapus); hind coxa and femur dark brown; apical half of metasoma reddish brown	C. kohkongensis Fischer, 2010
