Distribution
The species has previously been recorded from several European countries: Austria, Belgium, Denmark, Finland, Germany, Great Britain, Italy, Moldavia and Russia (Debauche 1947; Hellen 1971; Kozlov 1971, 1988; Mineo 1979; Rollard 1991; Kononova & Fursov 1999). Therefore, it is new for France and Portugal (Azores).
Biology and Ecology
Its known hosts are spider eggs, especially of the families Argiopidae and Theridiidae, Rollard (1991) cited Coelotus terrestris Wid., Dysdera erythrina Walker, Micryphantes sp., Tegenaria picta Sim. and Theridium sp.
Description
Morphology. The female has been redescribed and well illustrated (Kozlov 1988; Kononova & Fursov 1999). On the contrary, male morphology has yet to be described and is provided here. Wings are narrow with long marginal setae (Fig. 4A, B), forewing 6.5 times as long as the maximum width with longest marginal setae almost as long as the maximum wing width, hind wing 8.5 times as long as the maximum width with longest marginal setae 1.6 times as long as the maximum wing width. Kozlov (1971, 1988) illustrated the forewing, but his drawing is erroneous: the wing is too wide (4.5 times as long as the maximum width) and has marginal setae that are too short (the longest 0.6 times as long as the maximum wing width). Antennae with 11 free segments; the 7 funicular segments are subequal and the last segment shows an indistinct suture in its middle (Fig. 4C). Abdominal T1 and T2 have numerous ridges, close to each other on T2 (Fig. 4D). Genitalia have well developed digiti (Fig. 4E). These males appear closely related to those of B. japonicusHNS Kononova and Fursov; that species, however, shows slightly narrower forewing(6.6 times as long as the maximum width) with longer marginal setae (longest 1.3 times as long as the maximum wing width).
