Bembidion (Desarmatocillenus) foochowense Lindroth, 1980

( Figs. 2 View Figs , 17 View Figs )

Bembidion (Desarmatocillenus) foochowense Lindroth, 1980: 200 . Cillenus (Desarmatocillenus) foochowensis: MARGGI et al. (2003) : 272; LORENZ (1998): 200; LORENZ (2005): 216. Bembidion (Desarmatocillenus) foochowense: TOLEDANO (2008c) : 95.

Material examined. TAIWAN: Lunglungchi, Fulung, Taipei Hsien, 31.vii.2001, Terada lgt., 1 J 3 ♀♀ ( KTHJ, CTVR).

Type ( China, Fujang) seen ( BMNH).

Diagnosis. A “ Cillenus -like” species, very similar to Bembidion aestuarii (Uéno & Habu, 1955) but differing from it by a shorter metatrochanter (less than half as long as the metafemur), more diffuse and more extended dark elytral spot reaching the suture, and slightly lighter colour of the pronotum ( Fig. 2 View Figs ).

Male genitalia ( Fig. 17 View Figs ). Median lobe of aedeagus with ventral margin almost rectilinear, bent ventrally at apical fifth. Small complex of typical “ Cillenus -like” sclerites in middle of endophallus and coarse pack of thick, poorly sclerotized membranes with scales filling anterior half of median lobe. A single, long and thick seta at the apex of each paramere in the specimen examined.

Distribution. Originally described from south-eastern China (Foochow = Fuzhou, Fujian Province). First record from Taiwan.

Remarks. As already pointed out by LINDROTH (1980), B. foochowense is very similar in external characters to small specimens of B. aestuarii except for the shorter metatrochanters. Given the male genital described here, B. foochowense and B. aestuarii seem to be sister species. Consequently the phylogenetic importance of the metatrochanter length in the Cillenus complex seems less relevant, and I emphasize once more my doubts about the validity of several subgenera of the complex.
