Family Fanniidae Schnabl & Dziedzicki, 1911 View in CoL View at ENA
A distinctive, modest-sized family known for ca 400 extant species currently classified in five genera ( Table 1 View Table 1 ). Species belonging to four fanniid genera have presently been scored for the distribution of setulae dorsally and ventrally (character A) on vein C ( Table 1 View Table 1 ) in agreement with the states described above.
• Euryomma Stein, 1899 , Fannia Robineau-Desvoidy, 1830 ( Fig. 2A–C View Fig ), Piezura Rondani, 1844 ( Fig. 2D View Fig )
All examined species are without ventral setulae behind the lower anterior row of alternating spinules and setulae of vein C (state A0): Euryomma americanum Chillcott, 1961 , E. muisca Grisales, Wolff & de Carvalho, 2012 , E. peregrinum (Meigen, 1826) , Fannia (50+ spp) incl. F. fuscula (Fallén, 1825) ( Fig. 2A–C View Fig ), Piezura graminicola (Zetterstedt, 1846) and P. pardalina Rondani, 1866 ( Fig. 2D View Fig ).
In Piezura graminicola and P. pardalina ( Fig. 2D View Fig ) rows of ventral and dorsal costal setulae on CS1 represent setulae displaced from the anterior spinule-setula rows; these accordingly consist of spinules only.
• Australofannia Pont, 1977 ( Figs 3A–D View Fig , 4A–B View Fig )
This genus consists of Australofannia spiniclunis Pont, 1977 and one undescribed species, both endemic to Australia ( Pont 1977). Examination of A. spiniclunis revealed a costal chaetotaxy deviating substantially from the usual fanniid pattern. Both sexes ( Figs 3–4 View Fig View Fig ) have vein C extensively setulose both ventrally and dorsally (state A8). Further, extensive weakening of the costal spinules has taken place: the lower anterior costal row is wholly setulose in both sexes, whereas the upper anterior row has retained the usual spinule-setula pattern in the female ( Figs 3A–C View Fig , 4A View Fig ), but with only a few spinules distally on CS 1 in the male sex ( Fig. 4B View Fig ).
