Etymology.

This species is named in honour of Jean Verbeke for his significant contributions to Afrotropical Tachinidae and for labelling our holotype of Filistea verbekei with the manuscript name we have chosen as the valid name of this genus.

Description.

Body length: 6-8 mm.

Male. Colouration: Head black or brownish-black in ground colour, covered with thick golden reflecting microtomentum. Antenna black. Palpus yellow. Tegula and basicosta black. Lower calypter smoky. Legs dark brown to black.

Head (Fig. 8 b–c, e): Frons at its narrowest point 0.5-0.6 times as wide as compound eye in dorsal view. Parafacial at its narrowest point 0.9-1.5 times as wide as postpedicel. Vibrissa arising slightly above lower facial margin. Gena 0.27-0.37 times as high as compound eye. Postpedicel 2.3-2.8 times as long as pedicel.

Thorax: Anepimeral seta well developed. Anatergite bare below lower calypter. Posterior lappet of metathoracic spiracle visibly larger than anterior lappet. Medial margin of lower calypter more or less abutting lateral margin of scutellum. Second costal segment ventrally bare. Costal spine varying from slightly shorter than to 1.5 times as long as crossvein r-m. Base of R4+5 with a few short setulae. Fourth costal section longer than sixth. Section of M1 between r-m and dm-m varying from slightly longer to as long as section between dm-m and bend of M1. Medial anterior surface of fore coxa bare. Preapical anterodorsal seta of fore tibia distinctly shorter than preapical dorsal seta. Preapical posteroventral seta of hind tibia shorter than preapical anteroventral seta.

Abdomen: General setulae of tergites 3 to 5 erect. Tergite 5 about 0.8-1.0 times as long as tergite 4.

Male terminalia (Fig. 9 c–d): As described for Filistea aureofasciata except: Surstylus in lateral view more or less parallel-sided in shape, distally rounded, with posterior margin straight (Fig. 9c). Lateral surface of surstylus covered with fine appressed setulae and with several robust setae along posterior 1/2.

Female differs from male as follows. Lower calypter yellowish-white. Frons at its narrowest point 0.9-1.1 times as wide as compound eye in dorsal view. Two proclinate orbital setae. General setulae of tergites 3 to 5 recumbent.
