Material examined. Holotype: female, Yunnan, Dali Yunlong Daorenshan , 3.VI.2009, Tan Jiangli, No202019709 . Paratype: 1female, 2 males, Yunnan, Dali Yunlong Daorenshan, 3.VI.2009, Tan Jiangli, No 202019710, 202019711, 202019712 .

Description. Female holotype. Body length 8.0 mm, fore wing length 6.0 mm.

Head. Antenna with at least 29 flagellomeres (apex missing); first flagellomere ca 1.3× length of second flagellomere. Face granulose ( Fig. 6D ). Clypeus granulose, convex, apical margin arched, slightly reflexed ( Fig. 6D ). Malar space weakly granulose, ca 0.5× basal width of mandible. Upper tooth of mandible longer than lower tooth, with a weak lamella. Frons granulose-punctate and without median carina. Vertex granulose ( Fig. 6E ). Interocellar distance 1.3× ocello-ocular distance and 2.0× distance between median and lateral ocelli; distance between lateral ocelli and eyes equal to diameter of ocellus ( Fig. 6E ). Temple mat, ca 0.5× as long as eyes in lateral view. Occipital carina evenly arched, reaching hypostomal carina at mandible base.

Mesosoma. Pronotum granulose dorsally and transversely striate ventrally. Mesoscutum granulose, granulosepunctate on notaulic area ( Fig. 4F ). Scutellum granulose. Metanotum granulose-punctate. Mesopleuron rugulose on its upper half, granulose-punctate on lower half, transversely striate below tegula, speculum weakly granulose ( Fig. 6B ). Metapleuron rugose, rugosity denser on juxtacoxal area ( Fig. 6B ). Propodeum ( Fig. 6C ) with area basalis triangular; area superomedia long and narrow, granulose, lateromedian longitudinal carina weak on area superomedia, gradually strong apically; area superomedia confluent with area petiolaris; area petiolaris rugose; area external granulose; area dentipara granulose-punctate; area lateralis granulose; costula developed; lateral longitudinal carina absent; propodeal spiracle oval.

Wing. Fore wing ( Fig. 6A ) areolet absent; portion of vein M between 2rs-m and 2m-cu ca 0.7× as long as 2rs-m. Marginal cell long, vein RS ca 2.3× longer than vein 2r& RS. Vein 1cu-a slightly distad of M& RS. External angles of second discal cell acute (75°). Hind wing with CU&cu-a slightly reclivous, 2-CU not connected with CU&cu-a, not intercepted.

Legs. Hind femur 6.0× longer than wide. Inner spur of hind tibia ca 0.6× as long as first tarsomere of hind tarsus. Tarsal claws strongly pectinate.

Metasoma. First segment ( Fig. 6G ) without glymma, ca 4.0× longer than width of postpetiole; petiole ca 2.3× longer than postpetiole. Second tergite ca 0.8× as long as first tergite, 2.1× longer than its apical width; thyridium oval, its distance from basal margin of tergite about equal to its length. Third tergite ca 1.6× longer than its apical width. Ovipositor and ovipositor sheath as long as apical depth of metasoma, with a weak subapical notch on upper valve.

Colour. Black. Scape and pedicel blackish brown, yellowish anteriorly; mandible brownish with medial portion yellowish brown; palpi yellow; tegula blackish brown; coxa black except hind coxa with a yellow mark dorsalapically; fore trochanter and trochantellus dorsally brownish, femur ventrally and telotarsus brownish, remainder of fore leg yellowish brown; mid trochanter, trochantellus and femur blackish brown, tibia infuscated basally and apically, yellowish brown medially, tarsus brown except basal tarsi 0.8 yellowish brown; hind leg black except tibia medially slightly blackish brown; first metasomal segment except extreme apically, basal 0.9 of second tergite and third tergite only basally black, remainder of metasoma reddish brown.

Distribution. China (Yunnan).

Comparison. This new species is similar to G. clara Townes, 1970 , but differs from the latter by having the mesopleuron rugulose on its upper half and granulose-punctate on lower half, scape and pedicel blackish brown and yellowish anteriorly, mandible brownish with medial portion yellowish brown, tegula mainly blackish brown, fore and mid coxae black, and hind leg black except tibia medially slightly blackish brown.

Etymology. Name derived from mauros (Greek for black) and kneme (Greek for leg), because of the almost entirely black hind leg.
