Parametriocnemus lundbeckii (Johannsen)

Metriocnemus lundbeckii Johannsen, 1905: 302.

Parametriocnemus lundbeckii (Johannsen); Sublette (1967: 5379); Sæther (1969: 115).

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 Sæther (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.
