Key 3 – Identification of the Physocephala antiqua View in CoL species-group.

1. Basal cell completely covered with microtrichia, and usually brownish in colouration .............................. 2

– Basal cell almost completely (or at least centrally) bare of microtrichia and hyaline ............................. 4

2. Wings obviously reduced in length, not reaching beyond apex of tergite 3 ( Fig. 11 View Fig ) ............................. .................................... P. brevipennis Camras, 1962 View in CoL

– Wing not obviously reduced, about as long as abdomen or at least extending beyond apex of tergite 3............................................................................... 3

3. Cell r 2+3 completely brown ( Fig. 21 View Figs 17–21 ); subcosta light yellow to yellowish-brown, obviously different in colour from radial veins ( Fig. 21 View Figs 17–21 ); legs orange-brown, lacking a blackish ring on hind femur or darkened tarsi ( Fig. 14 View Figs 13–16 ); scutum orange-brown with black central stripe and small two lateral black spots which may sometimes fuse with mid-stripe ( Fig. 17 View Figs 17–21 ); scutellum orange-brown ( Fig. 17 View Figs 17–21 ); larger species, wing length 6.3–7.6 mm .... P. guillarmodi View in CoL spec. nov.

– Cell r 2+3 hyaline apically ( Fig. 36 View Fig ); subosta dark brown, same as radial veins ( Fig. 36 View Fig ); at least hind femur with black markings, and apical tarsi black; scutum and scutellum sometimes blackish; smaller species, wing length 3.7–5.3 mm (based on 3 known Afrotropical specimens only) .................................... .......................................... P. pusilla (Meigen, 1804) View in CoL

4. Anepimeron with long setulae, about as long as maximum width of tibiae; dusting stripe on pleura distinct, narrow at anepisternum and broader when reaching notopleuron ( Fig. 34 View Figs 30–35 ), obviously contrasting with shining anterior half of anepisternum and anepimeron ( Fig. 34 View Figs 30–35 )............. P. ssymanki View in CoL spec. nov.

– Anepimeron at most with short setulae; any dusting stripe on pleura reaching notopleuron without widening, and sometimes indistinct. ....................... 5

5. 3 aristomeres, the basal one minute and easily overlooked; scape usually about three times as long as high ( Fig. 28 View Figs 25–29 ); gena black, and parafacia above gena mainly yellow ( Fig. 28 View Figs 25–29 ); frons with black longitudinal stripe reaching from vertex to base of antennae ( Fig. 26 View Figs 25–29 ); black facial stripe divided ventrally and reaching to mouth edge ( Fig. 28 View Figs 25–29 ); abdomen longer ( Fig. 25 View Figs 25–29 ), ratio of combined dorsal length of tergites 2+3: dorsal length of tergite 4 in ♂>3.8 ................................. P. larvata (Speiser, 1911) View in CoL

– 2 aristomeres (e.g. Fig. 28 View Figs 25–29 ); scape usually only about twice as long as high; gena and frons lack black markings; abdomen shorter, ratio of combined dorsal length of tergites 2+3: dorsal length of tergite 4 in ♂ <3.5 ........................................................................ 6

6. Wing completely hyaline ( Fig. 12 View Fig ) ........................... ...................................... P. claripennis Becker, 1923 View in CoL

– Wing with distinct brown to blackish markings ( Figs 9, 10 View Figs 7–10 ) ...................... P. antiqua (Wiedemann, 1830) View in CoL
