Bembidion (Ocydromus) shunichii Habu, 1973

( Figs. 14 , 26 )

Bembidion (Peryphus) shunichii Habu, 1973: 112 . Bembidion ( Ocydromus incert.) shunichii: LORENZ (1998) : 217; LORENZ (2005): 234. Bembidion (incertae sedis) shunichii: MARGGI et al. (2003) : 271. Bembidion shunichii: TERADA et al. (2005) : 171; TERADA (2006): 12.

Material examined. TAIWAN: Nanshichi, Wulai, Taipei Hsien, 23.xii.2001, Terada lgt., 2 JJ 2 ♀♀ ( KTHJ, CTVR).

Remarks. The species was originally described on the basis of three female specimens. This is the first description of the male genitalia ( Fig. 26 ). Median lobe of aedeagus rather thick, with pointed apex. Endophallus with spiral flagellum typical of the lenae -group, not forming a complete loop as in B. peleum ; well-sclerotized stylet placed dorsally and parallel to anterior part of flagellum. Flagellum tubular, its basal end slightly protruding from basal opening of median lobe.

In the original description, HABU (1973) described the species as completely lacking elytral microsculpture, while the specimens examined here show distinct microsculpture with extremely sharp and transverse cells, giving a strong, iridescent, bluish reflection to the elytra. The specimens otherwise completely agree with the original description.

Distribution. Taiwan (Taichung Hsien, Taipei Hsien).
