Head:
Antennae with 45 segments; scapus suboblique, dorsally longer than ventrally and 1.9 times as long as apical width; pedicel slightly shorter than half length of scapus; first flagellomere as long as its maximum width, its apex ventrolaterally rather flared; second flagellomere 1.2 times as long as its maximum width, its apex ventrolaterally slightly flared; third flagellomere not flared apically, and as long as 1.4 times its maximum width; median flagellomeres longer than their maximum width; terminal flagellomere acuminate, and 1.6 times as long as its maximum width; malar suture setose and indistinct; face largely smooth and shiny medially, distinctly punctate laterally; clypeus depressed ventrally and upper densely long setose; height of clypeus: distance intertentorial: distance tentorial ocular= 3: 5: 9; length of maxillary palp 0.7 times height of head; length of eye in dorsal view 1.6 times temple; temple smooth and densely short setose; frons between antennal sockets and ocelli deeply impressed; minimum distance posterior ocelli: narrower diameter of posterior ocelli: minimum distance between posterior ocellus and eyes= 4: 2.5: 9.
Mesosoma:
Length of mesosoma 1.9 times its maximum height; pronotum and propleuron smooth and shiny; mesoscutum and scutellum densely short setose, but mesopleuron glabrous; notauli narrow and deep along its length; scutellar sulcus deep and narrow, crenulate; metanotum with distinct mediolongitudinal carina; scutellum flattened and smooth, sparsely pubescent; propodeum densely long setose, without mediolongitudinal carina or groove medially.
Wing:
Fore wing: length of veins r: 3SR: SR1 = 5: 11: 34; length of veins 2SR: 3 SR: rm = 12: 11: 6; vein cua interstitial.
Hind
wing: length of veins SC+R: 1rm = 11: 4, vein 2SC+R longitudinal, short and about 0.3 times vein 1rm.
Leg:
Length of femur, tibia and tarsus of fore leg = 20: 23: 35; length of femur, tibia and basitarsus of hind leg = 22: 36: 13, and 3.1, 7.9 and 5.8 times their maximum width, respectively; tibia of hind leg without lateral furrow.
Metasoma:
First metasomal tergite slightly widened apically. First metasomal tergite largely smooth and shiny, and strongly raised carina medioposteriorly, narrow basally, wide apically, and narrowly areolate laterally, 1.1 times as long as apical width, with clearly differentiated lateral areas behind spiracles; second metasomal tergite glabrous with deep, lateral diverging grooves; the suture between second and third metasomal tergites narrow and deep, without crenulate; remainder of metasomal tergites smooth and shiny, without anterolateral carina or grooves; hypopygium obtuse apically, and not protruding beyond the apex of seventh metasomal tergite; length of ovipositor 1.2 times that of metasoma, and 1.1 times fore wing.
Colour:
Head reddishyellow; antennae brown; fore leg yellow; thorax reddishyellow; metasoma and hind leg pale brown; wings membrane subhyaline; metasomal tergites brightly yellow; ovipositor sheath blackishbrown.
Diagnostic characters
: This species is similar to
Coeloides guizhouensis
Yang
, but can be separated from latter by having the receded temple, the mesoscutum and the scutellum densely short setose, the notauli completely narrow and deep, the vein cua of fore wing interstitial, the mesosoma and metasoma yellowishbrown, and the second metasomal tergite with lateral raised areas.
Biology
: Unknown.
Etymology
: From longquan, referring to the location of the
type
specimen.
