Key to Afrotropical species of Diaparsis with white-banded flagellum

1. Flagellum with a conspicuous white band ( Figs 1, 2 ).......................................................... 2

- Flagellum without a white band, pale basally and gradually darkening towards apex, or more or less entirely brown or black....................................................................................................... Other species of the genus (see Khalaim 2013a and the description of D. umbrosa Khalaim & Sääksjärvi , sp. nov. in the present paper).

2. Flagellum very slender, subbasal flagellomeres 3.5× as long as broad ( Fig. 1 ). Foveate groove of mesopleuron absent ( Fig. 6 ). Flagellum with a white band near its middle, 13 apical flagellomeres black ( Fig. 5 ).................................................................................................... kanyawara Khalaim & Sääksjärvi , sp. nov.

- Flagellum not especially slender, subbasal flagellomeres 1.2–1.5× as long as broad. Foveate groove of mesopleuron well developed. Flagellum with a white band far behind its middle, 1 to 7 apical flagellomeres black....................... 3

3. Head with temple, in dorsal view, 0.4× as long as eye width ( Khalaim 2013b: Fig. 7 ). Propodeum with basal keel as long as apical area ( Khalaim 2013b: Fig. 9 ). Ovipositor sheath distinctly shorter than first tergite.............................................................................................................. nebulosa Khalaim, 2013

- Head with temple, in dorsal view, 0.5–0.6× as long as eye width. Propodeum with basal keel 0.5–0.7× as long as apical area. Ovipositor sheath much longer, 1.8–3.2× as long as first tergite................................................. 4

4. Three subapical flagellomeres black ( Fig. 11 ). Malar space 0.9× as long as basal width of mandible ( Fig. 9 ). Propodeum with basal keel obliterated. Fore wing with second recurrent vein distinctly postfurcal. Ovipositor distinctly sinuate apically, sheath 3.2× as long as first tergite ( Fig. 13 )....................................... sinuator Khalaim & Sääksjärvi , sp. nov.

- Seven subapical flagellomeres black ( Khalaim 2013a: Fig. 16 ). Malar space 0.4× as long as basal width of mandible. Propodeum with distinct basal keel ( Khalaim 2013a: Fig. 20). Fore wing with second recurrent vein interstitial ( Khalaim 2013a: Fig. 19). Ovipositor not sinuate apically, sheath 1.8× as long as first tergite ( Khalaim 2013a: Fig. 15 )..................................................................................................... interstitialis Khalaim, 2013
