Dolichurus


Dolichurus is a genus of cockroach wasps in the family Ampulicidae; they are generally found on dead wood, leaf litter, or on tree trunks. There are at least 50 described species in Dolichurus.
These wasps are small in size with an elongate body and slender appendages; legs are modified for running. Sexual dimorphism is not marked; antennae have 12 segments in females and 13 segments in males; females have six visible metasomal segments and males usually have only three visible segments. In females metasomal punctures are usually fine, almost impunctate with very sparse delicate punctures but the metasomal punctures of males are usually coarser.
Diagnostic characters of Dolichurus include a complete antennal platform that is not grooved or divided, and the absence of metallic coloration. The forewing has veins M and Cu diverging from M+Cu well after cu-a; there are three submarginal cells of which SM I is much less than twice as long as SM II measured along posterior side; the first intersubmarginal veinlet is angled; submarginal cell SM III is trapezoidal to nearly triangular; the first recurrent vein is received by SM II, and the second by SM III. Many species have whitish marks on the clypeus, mandible, frons, and collar.
This is a cosmopolitan genus with about 50 species worldwide.
Latreille erected the genus Dolichurus based on the type species Pompilus corniculus Spinola, 1808.
