Parametriocnemus lundbeckii (Johannsen)

Parametriocnemus lundbeckii

Material examined.
CHINA: Zhejiang Province, Tianmu Mountain,
30°18'44"N
,
119°26'35"E
, 7 males, 12.xi.1998, light trap, H. Zhou.
Remarks.
The species differs from other members of the genus by having a triangular, broad inferior volsella with bluntly rounded corner. The species is very similar to
Parametriocnemus stylatus
(Kieffer), but differs in the shape of the inferior volsella, and the preapical projection of the gonostylus is much smaller and pointed than that in
Parametriocnemus lundbeckii
(
Brundin 1956
). According to
Saether
(1969)
, the immature stages seem to be inseparable, and as
Parametriocnemus stylatus
is known to be very variable (see
Thienemann 1937
) it might be a synonym of
Parametriocnemus lunbdbeckii
.
Distribution.
The species has been recorded from the Oriental, Neotropical and Nearctic Regions, and occurs in both of Oriental and Palaearctic China.
