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).
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
x
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
.

Loboscelidia fulgens
, refers to the shining integument (Latin, adj).
