Bembidion conicolleDavid R. Maddison
Adult External Characteristics
Mirrors on intervals 2 through 7, outer mirrors broadly connected or isolated from inner mirrors. Pronotum only slightly basally constricted, relatively flat, generally with small carina, midlateral setae present or absent. Male protarsomere adhesive setae narrow.
Aedeagus narrower than in B. litorale, with less curved ostial sclerotized strip. Ventral Sclerite Patch large, with unscaled (but occasionally striated) dorsal ridge. Ostial microtrichial patch dense and narrow.
Comparison with Related Species
Very similar to B. litorale; they may be conspecific (see Maddison, 1993, for details). The main external differences are in the prothorax: that of B. conicolle is flatter, with straighter sides and a wider base; the midlateral seta is constantly absent in B. conicolle, only inconstantly so in B. litorale. Most B. conicolle have a minute basilateral carina on the pronotum, whereas it is absent in the observed B. litorale. The fourth elytral stria is generally straighter in B. conicolle (although in some specimens it is abruptly sinuate). The outer mirrors are broadly connected to the inner elytral mirrors in most, but not all, specimens of B. conicolle. Setae ed3 and ed5 are at the anterior margin of the silver spot in most specimens. For aedeagal differences, see Maddison (1993).
B. conicolle can be separated from the North American B. levettei by the lack of the prothoracic seta and the narrow protarsomere of the male in B. conicolle.
An eastern Palearctic form, from the Lena River, Lake Baikal, and Mongolian Peoples' Republic, east to the Ussur region and Japan.
