Additional material examined:

China: 3 ♂♂, Jiangsu, Nanjing, Agricultural University , VII.1991, leg. Cooter ( MMUM, cAss) .

Comment:

The original description of L. seriatum is based on “two examples” from “Yokohama” ( Sharp 1889). The name is a junior primary homonym and was replaced with the nomen novum Pseudolathra lineata by Herman (2003). The above type specimen, a male in good condition, is designated as the lectotype.

Redescription:

Body length 4.9-5.8 mm; length of forebody 2.9-3.1 mm. Habitus as in Fig. 15 . Coloration: head blackish-brown; pronotum and elytra reddish, with the postero-lateral portion of the elytra more or less extensively infuscate; abdomen dark-reddish; legs and antennae reddishyellow.

Head ( Fig. 16 ) approximately as broad as long; punctation coarse and sparse, in median dorsal portion very sparse; interstices without microsculpture, but with micropunctation, and glossy. Eyes large, longer than postocular region in dorsal view. Antennae slender, 1.9 mm long; all antennomeres oblong.

Pronotum ( Fig. 16 ) approximately 1.15 times as long as broad and approximately 1.05 times as broad as head; on either side of the impunctate midline with series of approximately 15 punctures, these punctures partly accompanied by additional punctures; punctation of lateral portions unevenly distributed; interstices without microsculpture.

Elytra ( Fig. 16 ) 1.0-1.1 times as long as pronotum; laterally with fine submarginal carina; punctation moderately coarse, arranged in several series; interstices without microsculpture. Hind wings fully developed.

Abdomen distinctly narrower than elytra; punctation very fine and dense; interstices with microsculpture; posterior margin of tergite VII with palisade fringe.

♂: protarsomeres I-IV strongly dilated; sternite VII with almost truncate posterior margin, pubescence unmodified; sternite VIII oblong, posterior excision narrow and deep, almost reaching middle of sternite ( Fig. 17 ); aedeagus 0.9 mm long, shaped as in Figs 18-19 .

♀: not available.

Distribution:

Pseudolathra lineata was previously known only from Japan. The above specimens from Jiangsu ( Map 1 ) represent the first record from China. They were collected in the same locality as P. regularis .
