Diagnosis
Easily distinguished from all known congeners by long sickle-shaped bulbal process and by unique shape of procursus (long, S-shaped, with subdistal ventral pointed process; fig.
580 in
Huber 2011
); from other species in the
buatong
group also by longer than wide female internal genitalia (
Fig. 170
).

Description
(female)
In general similar to male (
Fig. 149
; cf.
Huber 2011
), but eye triads on low humps and closer together (distance PME-PME: 185 µm) and black mark at ocular area smaller. AME present as in male. Tibia
1 in
3 females
: 5.5, 5.6, 6.1. Epigynum longer than wide, mostly weakly sclerotized, with large dark ‘knob’ at posterior margin, anterior internal arch visible through cuticle (
Figs 169
,
187–188
); posterior plate laterally slightly more sclerotized. Internal genitalia as in
Figs 170
and
189
.
Distribution
Known from two localities in southern Thailand and northern mainland Malaysia (
Fig. 153
).
