description: Key to males of Afrotropical Culiciomyia based on habitus and genitalia
Culex milloti is not included in this key as it is known only from the larva. Characters used in the key for those species that were not collected by us are taken from published descriptions and drawings. Arrows in the figures point to features mentioned in the couplets. Barbed setae on the subapical lobe of the gonocoxite, when present, are often quite difficult to see because they are very small, delicate and thin, and often obscured by setae.
1 Maxillary palpus 0.16 length of proboscis (Fig. 41A); São Tomé and Príncipe only........................ cambournaci
- Maxillary palpus longer than proboscis (Fig. 41B)........................................................... 2 2(1) Palpal comb with 4 scales; Madagascar only........................................................... pandani
- Palpal comb with more than 4 scales...................................................................... 3
3(2) Palpomere 4>0.5 length of palpomere 5 (Fig. 42A).......................................................... 4

4(3) Distinct apicolateral pale spots on terga 3–7; sterna with pale apical bands; palpal comb with 11–14 scales; no basal protrusion or arm on paraproct; subapical lobe of gonocoxite without barbed setae.................................... mongiro

5(4) Palpomere 4 0.75 length of palpomere 5 (Fig. 44A); paraproct basal arm/protrusion>0.40 length of paraproct (Fig. 45A); gonocoxite with distinct ventrolateral patch of long piliform setae (Fig. 46A);................................. subaequalis
- Palpomere 4 0.50–0.65 length of palpomere 5 (Fig. 44B); paraproct basal arm/protrusion <0.40 length of paraproct (Fig. 45B); gonocoxite without obvious ventrolateral patch of setae, setae present are short (Fig. 46B)............. pseudosubaequalis
6(3) Gonostylus with single small recurved horn on upper margin; subapical lobe with a broad stout seta laterally separated from the other 2 stout rod-like setae (Fig. 47A)................................................................ macfiei
- Upper margin of the gonostylus with “spinelets” forming a crest; bases of the 3 rod-like setae more or less equally close to each
other (Fig. 47B), except for Cx. cinereus, which has 1 rod-like seta more distally positioned from the other 2 rod-like setae..................................................................................................... 7
7(6) Palpal comb scales spatulate with rounded apices (Fig. 48A)......................................... semibrunneus

- Apical delicate setae on gonocoxite borne on an obvious protuberance; large foliform seta g of subapical lobe truncated (Fig. 50B).......................................................................................... eouzani 10(8) Palpal comb scales all similar in shape but may vary in length (Fig. 51A)........................................ 11
