Euryomma Stein View in CoL

Euryomma Stein, 1899: 19 View in CoL . Type species: hispaniense Stein, 1899 = peregrinum (Meigen, 1826) .

Diagnosis

Head of male and female without sexual dimorphism, dichoptic in both ( Figure 1B View Figure 1 ); male with two pairs of orb; thorax with first presutural dc less than half or with half the length of the second presutural seta; two strong katepisternal setae with a weak median one; wing with vein A 2 slightly curved and imaginary extension of anal veins meeting near margin of the wing ( Figure 1A View Figure 1 ); abdomen wider before posterior margin of second tergite; male with cercal plate formed by cerci fused on different parts (basally, median area or apically); male without bacilliform process ( Figure 1E View Figure 1 ); aedeagus sclerotized and elongated; female with two spherical spermathecae; larval integument reticulated and bearing spicules ( Chillcott 1961; Roskošný et al. 1997).

Geographical distribution

Most species of Euryomma are found in the Neotropical region, and two species occur in the Nearctic region ( Chillcott 1961). One species, E. peregrinum (Meigen, 1826) , is cosmopolitan ( Pont 1977a, b, 1989).
