Type material.

Holotype male: Viet Nam: Tuyen Quang Prov., 360 m, Na Hang Reserve, 16-20 May 1997, FIT, S. B. Peck, 97-10 (CNC). Paratypes: 3 males same data as holotype; 1 male: 20-24 May 1997, 97-13; 1 male: 300 m, 97-17; 1 male: Ha Tinh, Huong Son, 450 m, 18°22'N, 105°13'E, 22 April-1 May 1998, L. Herman, LT (BME, CNC).


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  .

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.
