Megaselia sacatelensis View in CoL new species ( Figs. 26 View FIGURES 19 – 27 , 58 View FIGURES 53 – 62 , 88 View FIGURES 87 – 92 , 119 View FIGURES 109 – 124 )

Diagnosis. Male. In the group VIII key of Borgmeier (1966), M. sacatelensis keys to M. longipennis Malloch which was described from females only (1912). Borgmeier examined many specimens of both sexes that he designated as M. longipennis . Closer examination reveals that it is almost certain this material contains multiple species. M. sacatelensis has a characteristic coloration ( Fig. 26 View FIGURES 19 – 27 ), which does exhibit variation but is recognizable in pattern in over 100 specimens observed, unlike the generally varied coloration Borgmeier noted for M. longipennis . Additionally, the halteres on M. sacatelensis are dusky yellow, almost a light brown, in contrast to the “pale yellow” halteres described by Borgmeier (1966). Lastly, M. sacatelensis has a characteristic hypandrium with two darkened and elongate processes ( Fig. 119 View FIGURES 109 – 124 ) that fold over each other when the genitalia are withdrawn ( Fig 88 View FIGURES 87 – 92 ). Again, slide mounting of specimens is absolutely essential with Megaselia to eliminate errors and redundancy.
