Aphaniosoma socium Collin, 1949

Remarks

The listing of A. socium Collin, 1949 as present in Egypt ( Ebejer 1998) was an error, a lapsus of script – no specimen or literature record is known from Egypt. Given its habitat association and current distribution, it is unlikely to be present along the eastern Mediterranean coast or in the Middle East. It is a dark species with a uniformly grey scutum and scutellum. All setulae on the frons are of equal length and the male has a characteristic semicircular membraneous area dorsally between tergite 5 and 6. The pregenital sternite is square-shaped with two small, also square-shaped projections from the posterior margin as illustrated by Collin (1949: 133, fig. 2).

Distribution

Czech Republic, Germany, Great Britian ( Collin 1949; Ebejer et al. 2001; Bährmann 2006).
