Diagnosis. Recognised by the broadly ovate body; the short, flat head; the frons lacking a flange-like hood; the ocelli placed near to eyes on vertex, relatively widely separated by a distance less than three times their diameter in males and less than five times their diameter in females; the antennae originating on the ventral margin of the head; the membrane with a single cell; and the two-segmented tarsi.

Distribution. Widely distributed in southern Europe, the Middle-East, Far East, Africa, and Asia, including India, Japan, Korea, and Sri Lanka ( Akingbohungbe 1996).

Five species are known to occur in India.

Note. Kerzhner & Josifov (1999) in their catalogue indicated that Turnebus Distant and Skapana Distant were not synonyms of Isometopus , but did not give reasons why. Akingbohungbe (1993) recognized two subgenera, Isometopus Fieber and Jehania Distant (type species: Jehania mahal Distant, 1911 ).
