Abstract
This study reclassifies a complex of six pattern-winged species in the genus Dicranomyia. There is evidence throughout the literature that these taxa have been improperly classified, producing multiple synonyms and confusion in identification. Through a combination of literature searching, examination of the specimens referenced in the literature, and photography of newly prepared specimens, we determined the valid species in the group. We produced a dichotomous key for diagnosis supplemented with images and used this information to identify a crane fly species infesting water treatment plants in Nevada and Colorado that reduces the biofilm used in treating the water. Limnobia concinna Williston, 1893 is recognized as a new synonym of D. defuncta (Osten Sacken, 1860) and the synonymy of Limonia pemetica Alexander, 1939 with D. simulans (Walker, 1848), and of D. negligens (Alexander, 1927) with D. venusta (Bergroth, 1888) are confirmed. Dicranomyia pellucidiguttata Dietz is removed from synonymy of D. defuncta and placed in the genus Limonia, as L. pellucidiguttata (Dietz), new combination. Most literature records of D. simulans refer to D. defuncta. Dicranomyia defuncta is identified as the species infesting the water treatment plants.
