Type material.

Holotype, ♂ (ZUH), "S. China: Hunan, Chenzhou, Yizhang, Mang Mts, 7.V.1989, Ben-Zhu Dai, No. 301".

Diagnosis.

Length of body about 3.8 mm; antennal segments about 43; area below pterostigma slightly infuscate; length of eye in dorsal view about equal to temple in dorsal view; mesoscutum about as long as wide; anterior groove of metapleuron crenulate; precoxal sulcus widely crenulate (Fig. 349); medio-posterior depression of mesoscutum elongate (Fig. 344); propodeum with medio-longitudinal carina anteriorly (Fig. 345); vein CU1b of fore wing medium-sized; vein 1r-m of hind wing 0.6 times as long as vein 1-M (Fig. 343); second submarginal cell of fore wing narrowed apically; first tergite about as long as wide (Fig. 345).

Description.

Holotype, ♂, length of body 3.8 mm, of fore wing 4.1 mm.

Head. Antenna with 43 segments and 1.3 times as long as fore wing; third segment 1.2 times as long as fourth segment, length of third, fourth and penultimate segments 3.0, 2.5 and 1.5 times their width, respectively (Figs 342, 350); length of maxillary palp 1.1 times height of head; labial palp segments slender; occipital carina moder ately close to hypostomal carina and medio-dorsally absent; hypostomal carina wide; length of eye in dorsal view about equal to temple; frons medially convex, depressed behind antennal sockets, largely smooth and glabrous; face largely punctate, medially distinctly elevated (Fig. 347); width of clypeus 2.7 times its maximum height and 0.6 times width of face; clypeus rather convex, distinctly protruding forwards and coarsely punctate and its ventral margin concave and thick (Fig. 347); hypoclypeal depression large (Fig. 347); malar suture absent; length of malar space 0.7 times basal width of mandible; mandible triangular and with narrow ventral carina (Fig. 348).

Mesosoma. Length of mesosoma 1.3 times its height; dorsal pronope absent; pronotal side smooth, but medial groove and oblique groove coarsely crenulate (Fig. 349); epicnemial area mainly smooth dorsally except for some fine punctures; precoxal sulcus widely crenulate (Fig. 349); rest of mesopleuron smooth; pleural sulcus smooth; notauli absent on disc, only anteriorly present with pair of short smooth impressions (Fig. 344); mesoscutum glabrous except for row of setae along imaginary notaulic courses; medio-posterior depression of mesoscutum elongate (Fig. 344); scutellar sulcus wide and coarsely crenulate (Fig. 344); scutellum slightly convex medially, smooth; propodeum with nearly complete medio-longitudinal carina and remainder largely reticulate-rugose, posteriorly areolate (Fig. 345).

Wings. Fore wing (Fig. 343): pterostigma triangular; 1-R1 reaching wing apex and 1.3times as long as pterostigma (Fig. 343); r:3-SR:SR1 = 7:60:100; 2-SR:3-SR:r-m = 40:60:16; 1-M slightly curved; 1-SR+M sinuate and SR1 nearly straight; m-cu postfurcal; cu-a subinterstitial; first subdiscal cell closed, 3-CU1:CU1b=2:1; apical quarter of M+CU1 sclerotized. Hind wing (Fig. 343): M+CU:1-M:1r-m = 33:45:27; cu-a straight; m-cu completely absent.

Legs. Length of femur, tibia and basitarsus of hind leg 4.0, 8.0 and 5.0 times as long as wide, respectively; hind femur and tibia with medium-sized setae. (Fig. 346)

Metasoma. Length of first tergite about equal to its apical width, its surface evenly convex medially, dorsally coarsely rugose and laterally with longitudinally striate; dorsal carinae protruding, remain separated from each other and reaching apex of tergite (Fig. 345); second tergite mainly smooth (except for some indistinct striae) and following tergites entirely smooth.

Colour. Black; antenna (but scapus and pedicellus yellowish-brown), head (but near eyes yellowish-brown), second and following tergites dark brown; clypeus and mandible yellowish-brown; palpi, tegulae and legs yellow; pterostigma and veins brown; wing membrane subhyaline, but area below pterostigma slightly infuscate.

Distribution.

*China (Hunan).

Biology.

Unknown.

Etymology.

Name derived from “macula” (Latin for “spot”), because of the faintly spotted fore wings.

Notes.

The new species does not run to any species in the key by Chen and Weng (2005). Examination of the holotypes in FAFU (Fuzhou) showed that Rhogadopsis tabidula (Weng & Chen, 2005) comb. n.and Rhogadopsis pratellae (Weng & Chen, 2005) comb. n.are similar. However, both have fewer antennal segments (24 and 29, respectively), the area below the pterostigma is subhyaline and Rhogadopsis tabidula has the third tergite basally narrowly striate.
