Notes.
This species is newly recorded for
Vietnam
, although
Bui (2007)
published the same taxon first as
Euphaea ochracea
.
Hämäläinen (1985)
described
Euphaea pahyapi
from the peninsular part of
Thailand
based on male specimens.
Asahina (1985)
also described
Euphaea khaochongensis
from another province of the same area, but this was treated as a junior synonym of
E. pahyapi
by
Pinratana
et al
. (1988)
and in
Hämäläinen & Pinratana (1999)
.
Euphaea pahyapi
can be distinguished from all Vietnamese
Euphaea
species by the unique completely and evenly amber-colored wings of the male (
Fig. 18d
). Color pattern of the head is variable, entirely black as in the original description (
Hämäläinen 1985
) or with dirty blue markings as in Asahina's (1985) description and our specimens from
Vietnam
(Phu Quoc Island) (
Fig. 19b
). Abdomen and anal appendages are as in
Euphaea masoni
,
with hairs only on S3 (
Fig. 15d
). Vesicle of
Euphaea pahyapi
differs from that of
E. masoni
by being heart-shaped, pointed at its posterior margin (
Fig. 18f
) whereas it is ax-shaped with the posterior margin rounded in
E. masoni
(
Fig. 18e
). Female of this species is still undescribed.
The record of
Euphaea ochracea
from Kbal Chhay Cascades of Preah Sihanouk Province,
Cambodia
in
Kosterin
et al.
(2012)
is a misidentification and concerns in fact
E. pahyapi
(
Kosterin 2016, and
pers. comm.
)
