Discussion.
The species was so far only known from the male
types
from Selangor (Ulu Gombak Field Study Centre) and Pahang (Krau Game Reserve). Collection of new material by MKT in Bukit Fraser, Pahang represents a new locality for the species (
Fig. 1
A). Collection of female specimens also allowed the description of the female for the first time (
Fig. 1
B).
Descriptions (female).
Tenth abdominal tergite with distinct medial groove, apex terminating into two broadly and gently rounded lobes, with a shallow emargination in between (
Fig. 1
C). Epiproct triangular. Cercus swollen, terminal end with a conical obtuse process pointing internally (
Fig. 1
C). Subgenital plate broader than long, with lateral margins converging; apex terminating into two obtuse-triangular lobes, deeply excised in between (
Fig. 1
D). Ovipositor medium to short, compressed and blade-shaped; highest in circa middle of length; margins smooth; apex obtuse, dorsal and ventral valves equally long (
Fig. 1
E).
