Comments:
Careful examination of the unique
♀
HT of
Ph. bilobatum
from “
Philippine Islands
” in BMNH reveals that it has been misinterpreted by
Grösser (2008: 91)
who also recorded it from Java and Peninsular
Malaysia
. However, both records obviously represent two distinct species both of which are not conspecific with the HT of
Ph. bilobatum
. While the Malayan specimens illustrated by
Grösser (2008
, figs. 15, 107 & 108) relate to
Ph. hausleithneri
Brock, 1999
(see below), the Javanese specimens are in fact
Ph. jacobsoni
Rehn & Rehn, 1933
, a species described from Nongkodjadjar in western Java.
The HT of
Ph. bilobatum
is characteristic for the slender abdomen and narrow but acute and posteriorly extending lobes of abdominal segments VII and VIII and the five very prominent and triangular, saw-like teeth of the interior lobe of the profemora. Both features frequently distinguish it from the Javanese and
Malaysia
specimens erroneously attributed to
Ph. bilobatum
by
Grösser (2008: 91)
. Unfortunately, the typelocality is very inexact and no further material that definitely belongs to this species appears to have been recorded subsequently. Detailed photos of the HT in BMNH are available online at the
Phasmida
Species File http://phasmida.speciesfile.org (author: Paul D. Brock). Body length 65.0 mm.
