Idris rufescens (Kieffer)

Huggert (1979) listed adejensis Huggert , flavicornis Kieffer and kiefferi Masner as synonyms.

Material examined. Two females collected in a yellow pan trap at Remedios, Island of S. Miguel , Azores, Portugal, on 1 September 1991.

The species has previously been recorded from several European countries: Austria, Bulgaria, Croatia, France, Hungary, Italy, Spain (including the Canary Islands) and Sweden(Huggert 1979). Therefore, it is new for Portugal (Azores).

Hosts are unknown, but probably spider eggs.

Morphology. The species was redescribed and illustrated by Huggert (1979) who recognized several forms: most specimens, especially those from south Europe, are blackish with a paler abdomen, specimens from Sweden and some specimens from Hungary are brownish with a reddish abdomen, while specimens from the Canary Islands are more shiny and show broader wings with infumation. Females from Azores are brownish with paler head, antennae (except scapes) and legs, and look like the Canary Islands form. The forewing (Fig. 5A) and the hind wing (Fig. 5B) are broader (width/length or W/L=0.38 and 0.23, respectively) than in the Huggert (1979)’s specimen (W/L=0.34 and 0.18, respectively). The antenna (Fig. 5C) shows a longer pedicel and first funicular segment (L/ scape length=0.54 and 0.29, respectively) than in the Huggert (1979)’s specimen (0.38 and 0.18, respectively). The abdomen (Fig. 5D) seems less broad (W/L=0.77) than in the Huggert(1979)’s specimen (W/L=0.80).
