Remarks

Collin described this species from a single specimen ( Collin 1949: 142–143) which he considered as “Almost certainly a male but hypopygium hidden owing to incurved abdomen”. The single specimen is listed as the holotype by Pont (1995: 147–148). It perfectly fits the description of this species bears no name label but bears a round red bordered ‘Type’ label. It is in reasonably good condition ( Fig. 77A ). A specimen from Israel ( Fig. 77C ) shows the relative lengths of the male posterior tergites of the abdomen to be identical and which are characteristic of this species. The illustration of the hypopygium provided here ( Fig. 78 ) is based on another specimen from Israel.

Distribution

Egypt. New record for Israel.
