Diagnosis
Vein 1r-m of hind wing 0.7–1.0 times as long as vein 1-M (Fig. 335); anterior groove of metapleuron crenulate; posterior groove of pronotal side largely absent and remainder nearly smooth; first tergite elongate and with median carina (Fig. 337); medio-posterior depression of mesoscutum absent (Fig. 336).
Description
Male from Bamaoxi, length of body 2.8 mm, of fore wing 2.9 mm.
Head. Antenna with 32 segments and 1.3 times as long as fore wing; third segment 1.3 times as long as fourth segment, length of third, fourth and penultimate segments 4.0, 3.0 and 2.5 times their width, respectively (Fig. 338); length of maxillary palp 1.2 times height of head; labial palp segments slender; occipital carina rather close to hypostomal carina and dorsally absent; hypostomal carina wide; length of eye in dorsal view 3.8 times temple; frons rather depressed anteriorly and glabrous, largely smooth; face largely coarsely punctate and with distinct smooth interspaces, medially elevated (Fig. 339); width of clypeus 2.9 times its maximum height and 0.65 times width of face; clypeus rather convex, distinctly protruding forwards and coarsely punctate and its ventral margin slightly concave and thin, acute (Fig. 339); hypoclypeal depression large (Fig. 339); malar suture absent; length of malar space 0.3 times basal width of mandible; mandible triangular and with narrow ventral carina (Fig. 340).
Mesosoma. Length of mesosoma 1.3 times its height; dorsal pronope absent; pronotal side smooth, but posterior groove partly impressed and narrowly superficially crenulate (Fig. 334); epicnemial area mainly smooth dorsally except for some fine punctures; precoxal sulcus medially oblique and moderately crenulate (Fig. 334); rest of mesopleuron smooth; pleural sulcus smooth; mesosternal sulcus shallow and moderately crenulate; anterior groove of metapleuron crenulate; notauli absent on disc, only anteriorly with pair of narrow and short smooth impressions; mesoscutum glabrous except for row of setae along imaginary notaulic courses and strongly shiny (Fig. 336); medio-posterior depression of mesoscutum absent; scutellar sulcus moderately wide and coarsely crenulate (Fig. 336); scutellum slightly convex medially, smooth; propodeum with nearly complete medio-longitudinal carina and remainder largely smooth (Fig. 336).
Wings. Fore wing (Fig. 335): pterostigma triangular; 1-R1 ending at wing apex and 1.4 times as long as pterostigma; r:3-SR:SR1 = 4:41:69; 2-SR:3-SR:r-m = 28:41:12; r widened; 1-M and SR1 slightly curved; m-cu narrowly postfurcal; cu-a subinterstitial; first subdiscal cell closed, CU1b medium-sized; apical quarter of M+CU1 sclerotized. Hind wing (Fig. 335): M+CU:1-M:1r-m = 20:17:13; cu-a straight; m-cu completely absent.
Legs. Length of femur, tibia and basitarsus of hind leg 4.5, 8.5 and 5.2 times as long as wide, respectively; hind femur and tibia with medium-sized setae (Fig. 341).
Metasoma. Length of first tergite 1.5 times its apical width, its surface keel-like convex and largely smooth, its dorsal carinae united at basal 0.3 and with long median carina (Fig. 337); second suture slightly indicated; second and following tergites smooth.
Colour. Dark brown, head (except medio-dorsally and posteriorly), scapus and apically pedicellus brownish-yellow; notaulic courses, mesoscutum laterally, mesopleuron antero-dorsally, streak below precoxal sulcus, apex of second, apex and base of following tergites yellowish-brown; pterostigma dark brown; remainder of antenna and veins brown; palpi, tegulae, legs and metasoma ventrally pale yellow; wing membrane subhyaline.
Variation. Second male from Bamaoxi has 34 antennal segments, length of fore wing 3.0 mm and surroundings of medio-longitudinal carina of propodeum finely crenulate.
Molecular data. None.
Distribution
China (Fujian, Hunan).
Biology
Unknown.
Notes
The males run in the key by Chen and Weng (2005)[1] to Opius diutius Chen & Weng, 2005. Rhogadopsis longuria differs by having the propodeum with a nearly complete medio-longitudinal carina and remainder largely smooth (entirely reticulate-rugose in Opius diutius), the width of the clypeus about 3 times its height (about twice), the length of the malar space 0.3 times the basal width of mandible (0.6 times) and the first tergite with a keel-like convexity medially (flattened medially and without keel).
