Minagenia fulvifemoralis Ji et Ma , sp. nov.

( Figs 1–21 )

Diagnosis. The new species clearly differs from similar Minagenia montisdorsa Dreisbach, 1953 and other congeners by combination of characters: pronotum anteriorly not vertical; gonostylus stout, with long setae apically and medially, inner margin with right angle and long setae medially ( Figs 18, 19 ); mid and hind femorae reddish-brown.

Description. Female ( Figs 1–7 ). Body length 5.5–7.0 mm. Clypeus slightly elevated, anterior border nearly truncate medially ( Fig. 1 ), with dense, small punctures; labrum shortly produced, anterior border slightly convex; mandible apically bidentate ( Fig. 1 ); frontal line shiny, reaching to median frons ( Fig. 1 ), frons and vertex with dense, small punctures; ocelli in right triangle ( Fig. 2 ), ocellar area slightly elevated; A3 three times longer its width; ratio POD: OOD: Od: OCD = 10: 5: 4: 6; HW: HL = 35: 27; relative length in dorsal view of A1, A2, A3, A4, A5, A8, A11, A12 = 10, 5, 11, 11, 10, 8, 7, 8.

Ratio length pronotum and mesoscutum medially = 3: 7, pronotum with dense, small punctures, posterior margin of pronotum slightly angulate medially; mesoscutum with dense, small punctures, parapsids nearly complete, reaching close to pronotum; relative length scutellum, metanotum, metapostnotum and propodeum medially = 12, 5, 5, 25, scutellum elevated, with dense small punctures; metanotum as long as metapostnotum ( Fig. 3 ), metanotum with dense small punctures; metapostnotum transversally striate, anterior and posterior border medially almost parallel, distinctly longer than laterally, posterad nearly arcuate ( Fig. 3 ); propodeum densely punctate, without line ( Fig. 3 ). Second and third radiomedial veins convex and parallel ( Fig. 4 ), Cu of fore wing reaching apical margin ( Fig. 4 ). Relative length fore, mid and hind femur/tibia = 54/48, 65/60, 90/96; claws symmetric, bifid, inner teeth obliquely truncate ( Fig. 7 ); tarsal segment 5 beneath without spines.

Metasoma not petiolate, sternum 2 without transverse furrow; sternum 6 strongly compressed, with a distinct longitudinal ridge ventrally ( Fig. 6 ).

Black; mandible apically reddish-brown, labial and maxillar palpi brown, scape ventrally with yellowish stripe, fore coxae apically pale yellowish-brown, mid and hind femorae reddish-brown, inner side of mid tibia and basal half of hind tibia inconspicuously brown. Head, mesosoma, metasoma and legs with short whitish setae, metasomal sternum 6 with long, whitish setae.

Male ( Figs 8–21 ). Differs from female by follows: body length 6.0 mm. A1, A2 and fore tarsus mostly brown, fore femora apically, fore tibia and fore tarsus fulvous, hind femora except apical part reddish-brown. Propodeum with long whitish setae. Head as in Figs 8, 9 . A1 carinate beneath; ratio POD: OOD: Od: OCD = 8: 5: 3: 4; HW: HL = 5: 4; relative length of A1, A2, A3, A4, A5, A8, A12, A13 = 9, 4, 9, 9, 9, 9, 7, 9. Relative length pronotum and mesoscutum medially = 15: 32; parapsids fine, near complete; relative length scutellum, metanotum, metapostnotum, and propodeum medially = 15, 6, 6, 26; propodeum with shiny inconspicuous longitudinal median line ( Fig. 10 ). Wing as in Figs 11, 12 . Relative length fore, mid and hind femur/tibia = 45/32, 50/50, 72/80; fore claws asymmetric ( Figs 13, 14 ), inner claw bifid ( Fig. 13 ); mid and hind claws symmetric, mid claws bifid ( Fig. 15 ), hind claws simple ( Figs 16, 17 ). Metasomal sternum 7 strongly compressed; gonostylus stout, with long setae apically and medially, inner margin with right angle and long setae medially ( Figs 18, 19 ); hypopygium (sternum 8) with tuft of long setae ( Figs 20, 21 ).
