Aethiopomyia gigas (Stein, 1906) Figures 6-10 , 21-30

Syntypes.

1 ♂, 2 ♀ (see Pont and Werner 2006: 51 for details)

Diagnosis.

Length of body. 11.0-15.0 mm (♂♀). Similar to A. arguta , differing as follows: Head. Frons, fronto-orbital plate, parafacial, face, and gena reddish yellow, silver pruinose under certain lights. Palpus yellow. Thorax. Scutum ground color yellow, four broad black vittae laterally and one median white-silver pruinose vitta. Scutum laterally yellow, scutellum yellow. Pleurae mostly yellow; anepisternum and anepimeron mostly dark brown, Lower calypter broad, ca. 2.5 × as long as the upper one. Haltere yellow. Calypters yellowish with brown margins. Legs. Color and chaetotaxy as in A. arguta . Abdomen. Almost all black, with some grey pruinescence along the margins of the tergites, under certain lights. Abdominal sternites with strong setae. Sternite 5 quadrangular with two strong setae at middle (Fig. 21 ). Terminalia ♂. Cercal plate and surstylus as in Figs 22 and 23 ; aedeagus as in Figs 24 and 25 . Ovipositor as in Figs 26 and 27 ; only two spermathecae found (Fig. 28 ). Larva. One big larva found in ♀ abdomen (Fig. 29 ); detail of spiracle as in Fig. 30 . Cuthbertson (1938 in Skidmore 1985) recorded that the ♀ deposits a single late instar larva.

Note.

The species was keyed by Zumpt (1969). One ♂ and one ♀ (not types) from Spanish Guinea were dissected and illustrated. ♂: Uellebg. Benitogbt. /15-31.i.07 / G. Tessmann S. G.; ♀: Alou Benitogbt/16-31.vii.06/ Tessmann S. G. Recently, O’Hara et al. (2013) transferred Paleotachina Townsend from Tachinidae to Muscidae and placed in synonymy with Aethiopomyia and Paleotachina smithii Townsend, type species of Paleotachina , was synonymized with A. gigas .
