Diagnosis.
Westwood (1859) first described
O. cresphontes
as a variety of small
O. despectus
(
Westwood, 1848
)
and stated that the major differences are tubercles, spines and the scale-like wings pale yellow with a black margin on each side. Fortunately, this color pattern on the wings of
O. cresphontes
was shown in a drwing (Westwood 1859). In all the pictures of
O. despectus
(including two subspecies), it will be seen that
O. despectus
does not have such a wing coloration pattern. This is especially clear in the colorful plates by
Westwood (1848)
and photos on
Phasmida
Species File (PSF) (
Brock
et al.
2023
). Combining previous descriptions of spines or tubercles on the mesonotum of
O. cresphontes
, there are 2 tubercles on the anterior and posterior of mesonotum, but such a feature can also be found in
O. despectus
(
Brock
et al.
2023
,
Mandal & Yadav 2010
,
Redtenbacher 1908
,
Westwood 1848
, 1859). Our specimen has only one pair of strong spines near the anterior margin, and posterior of mesonotum with a pair of indistinct and tiny tubercles, This is different from what is known in both species (
Fig3 A–C, G
).
By checking the photos of the
holotype
of
O. despectus despectus
(
Westwood, 1848
)
on the PSF (
Brock
et al.
2023
), and plates drawn by Retdenbacher (1908), our specimen can be separated by the fifth abdominal tergite of
O. despectus despectus
with a relatively large hump as well. Both
O. cresphontes
and
O. despectus despectus
are distributed over a wide area in the southern foothills of the Himalayas (
Fig. 2
), but
O. cresphontes
is closer to Mêdog County (specimen locality). Combining geographic distribution, wing color patterns (Fig, 3A, C), we hereby consider the specimen we found to be
O. cresphontes
.
