Astochia africana View in CoL ; Oldroyd, 1980: 336.
Redescription: Based on lectotype ♀, unless otherwise stated.
Head: Antennae black with black bristles and setae (Uganda ♂); lectotype has both antennae broken off beyond segment 2. Mystax entirely black (other material including specimens from Ruwenzori and Malawi have a number of yellowish bristles just above epistomal margin). Occipital bristles (behind ocellarium) short, black and not proclinate. Proboscis black with white setae ventrally. Palpi black with black setae.
Thorax: Mesepimeral setae black; hypopleural setae mostly black but a few white ventrally. Mesonotal setae: dorsocentrals black, weak (especially those anterior of the transverse suture); humerals-fine, longish black setae only; presuturals-2 black; supra-alars- 2 black; postalars- 2 black; scutellars- 7 black marginal bristles (other specimens may have as few as 2). Metanotal callosities with black setae. Wings: 13,2 X 4,0 mm (length measured from humeral crossvein to tip; breadth through the fork of the radial sector); venation and microtrichial distribution as in Fig. 2 View Figs 2-6 . Legs: forecoxa with white (and a few black) setae anteriorly; hind-coxa with a single yellow or black bristle laterally. Femora dark red-brown to black with red-brown tips. Tibiae orange-brown. Tarsi darker than tibiae and with terminal tarsomeres dark red-brown. Setation of hind-femur: bristles black; longer setae black or white; minor setae yellowish (dorsal and proximal) or black (ventral and distal).
Abdomen: Tl-5 pruinose as thorax, T6 (and more distally) shiny black; sterna as terga. Ovipositor ( Fig. 3 View Figs 2-6 ) long and narrow. Terga with longish black setae anterolaterally, other setae shortish yellow. Sterna with longish, black and yellow setae. 0" genitalia (Uganda specimen drawn) as in Figs 4-6 View Figs 2-6 .
Material examined: KENYA: 3 ♀, lectotype and paralectotypes, Edge of forest on S. & E. slopes of Mt Kenya, 6 000- 7 000 ft, 3 -12.ii. 1911, S. A. Neave ( BM) ; 1 ♂ 2 ♀, 5-7 miles into Kenia Forest, near Luche R. 9 -1 10.ii.1911, T. J. Anderson ( BM) . UGANDA: 1 ♂ 1 ♀, Ruwenzori range, Namwamba Valley , 6500 ft, xii. 1934 - i.1935, B.M. E. Afr. Exp., F. W. Edwards ( BM) . MALAWI: 1 ♀, Mulanje Mnt., Likabula River Valley, riverine Brachystegia woodland, 2S- 30.xi.19 S0, Stuckenberg & Londt ( NM) ; 2 ♂ 4♀, Ntchisi forest reserve, 1 500 m, montane forest and woodland, 3 -4.xii.19 S0, Londt & Stuckenberg ( NM) .
Other recorded material: Oldroyd (1970) records the following. ZAIRE: 1 ♀, Stanleyville, Mahagi-Niarembe , x. 1935, Ch. Scops ; 1 ♀; Kivu, Kisenyi, ii. 192S, Ch. Seydel ; 1 ♀, Muturak, 3.ii.1933, Van Sacaghem . RUANDA: 1 ♂, Kisenyi , 1 SOO m, 18.xi.1961, A. Bertrand. These specimens are apparently housed in KMT .
Remarks: Ricardo examined three female specimens and while she referred to one as the type it is uncertain which of the three she was referring to. J hereby designate and label one of the three specimens as lectotype. The other two are to be considered as paralectotypes. This large species, active from October- February ( Table 1 View TABLE 1 ), is easily distinguished from the other four species. Adults are found in forests and along their margins.
