Megaselia pisanoi View in CoL new species ( Figs. 23 View FIGURES 19 – 27 , 31, 55, 85, 116)
Diagnosis. Male. In the group III key of Borgmeier (1964), M. pisanoi keys to M. goniata Borgmeier. These two species are remarkably similar but differ in a number of details. M. pisanoi has all legs brown, forelegs only slightly lighter ( Fig. 23 View FIGURES 19 – 27 ), while M. goniata has legs yellowish, hind legs darker. The hind femur fringe of M.
pisanoi has 10+ setae, while M. goniata has 7. The ratio of costal segments for M. goniata is such that C1 is 3.6x C3, but M. pisanoi has C1 typically 4.5x C3 or longer. The palpal setae for M. goniata are said to be 3 apically with one shorter laterally; M. pisanoi has at least 6 palpal setae. Lastly, the small size of M. goniata (1mm) is mentioned by Borgmeier; the slide mounted holotype of M. pisanoi measures over 1mm just from the front of the thorax to the end of T6 (not including the head which was dissected and mounted separately). Unfortunately, the holotype of M. goniata is almost completely destroyed and a complete comparison to type material was not possible. The midfemur of the holotype of M. goniata was examined, and does not appear as denticulate as M. pisanoi ; the widest part of the expansion on M. goniata is 0.11mm, while M. pisanoi is 0.16mm. M. goniata does appear to have a brushlike process on the left lobe of the hypandrium as seen in M. pisanoi ( Fig. 116 View FIGURES 109 – 124 ); further specimens are needed to confirm the status of these apparent sibling species.
