Identification
Members of the Epiphragma are distinguished from other crane flies by wing patterning and male genitalia characters. Specific identification of E. arizonense requires examination of the male hypopygium and wing venation patterns. The 2012 review by Alexander provides illustrations of these diagnostic features.
Distribution
Southern Arizona, United States south to Sinaloa, Mexico. GBIF records additionally document the from Chihuahua, Mexico.
Similar Taxa
- Epiphragma celatorBoth occur in southern Arizona and Mexico; E. celator was described from Michoacan, Mexico and its range extends north to southern Arizona, overlapping with E. arizonense. Distinguishing these species requires examination of male genitalia and wing characters.
- Epiphragma nebulosumAnother North American Epiphragma with overlapping distribution; E. nebulosum has broader range extending from Mexico through Central America. Wing patterning and male hypopygium structure differ.
- Epiphragma oreonymphaNorth American with similar taxonomic history; both were included in the 2012 review with first illustrations of diagnostic characters provided for E. oreonympha. Morphological comparison of male genitalia required for separation.
