Diagnosis.

This is one of four species, including Loboscelidia bakeri , Loboscelidia guangxiensis and Loboscelidia reducta that completely lack a medial vein. Loboscelidia fulgens can be separated from Loboscelidia guangxiensis in males by the shorter Rs vein, 1.5 × as long as R, versus twice as long in Loboscelidia guangxiensis , and having well-developed tibial flanges, which are lacking in Loboscelidia reducta . Loboscelidia fulgens can be immediately distinguished from Loboscelidia bakeri by lacking the uniquely up-domed propodeum characteristic of Loboscelidia bakeri .

Head (Fig. 5): length 1.8 × height in side view; eye asetose; frontal projection rectangular in front view; frons smooth, not microstriate; frons with low ridge extending from vertex along inner eye margin; vertex with transverse fovea, posterior expansion strongly curved in profile; gena without scale-like setae; scape striate, length 2.9 × breadth; flagellomere I length 2 × breadth; flagellomere II length 1.8 × breadth; flagellomere XI length 3 × breadth. Mesosoma: pronotal length 0.8 × breadth, without lateral carina, narrower than head in dorsal view; scutum with notauli reaching posterior margin; scutellum with fine dense striae laterally; metanotum with medial ridge, impunctate laterally, 0.4 × as long as scutellum; mesopleuron without scrobal sulcus; propodeum without transverse dorsal carina; legs (Fig. 38) smooth, polished; forefemoral flange 0.5 × femur length, flange maximum width 0.6 × width of tubular part of femur; foretibial flange 0.5 × tibial length, flange maximum width 0.4 x width of tubular part of tibia; midfemoral flange absent; midtibial flange 0.6 × femur length, flange maximum width 0.5 × width of tubular part of tibia; hindfemoral flange 0.8 × femur length, flange maximum width 0.6 × width of tubular part of femur; hindtibial flange 0.8 × femur length, flange maximum width 0.7 × width of tubular part of tibia; hindtibia with two longitudinal carinae on posterior margin; hindcoxa without longitudinal c arina on inner medial surface; forewing (Fig. 26) R1 length 0.4 × R length; cu-a absent; Rs length 1.4 × R length; Cu+M length 0.6 × A length; medial vein present, flat medially. Color: body brown to reddish brown; wing membrane brown-tinted, untinted along vein remnants; veins brown.

Etymology. The species name, Loboscelidia fulgens , refers to the shining integument (Latin, adj).
