Hoplistomerus quintillus: Oldroyd 1940: 317 (fig. 5e ơ clasper); 1980: 350 (catalogue); Hull 1962: 96.

Diagnosis: Size: Moderate (wing length from humeral cross-vein to tip 8–11 mm). Head: Eye wider than face (in anterior view measured at level of greatest head width). Relative proportions of antennal segments (scape, pedicel and postpedicel) 1.0:0.9:3.7 (i.e. scape and pedicel approximately equal; postpedicel more than three and a half times length of scape). Thorax: Presutural macroseta(e) absent.Anepisternal macroseta absent. Prosternal ventromedial setation short to absent. Male metatibial spur large. Scutellum with a transverse groove at mid-length.Wing cell m 3 with microtrichia limited to a narrow posterior strip. Prothoracic coxa and prosternum both dark red-brown. Prothoracic femur dark red-brown (tips may be paler). Abdomen: T3 setulae white laterally, golden medially. ơ genitalia as in Figs 30–32 .

Type specimens studied (all BMNH): KENYA: 2ơ paratypes, ‘Brit. E. Afr. / Mara R. / Masai Res. [Masai Mara Res., 01°26'S: 34°55'E], 11.ii.1914 / Capt. A. O. Luckman.’, ‘ Paratype / Hoplistomerus ơ quintillus Oldr. / det. H. Oldroyd 1940 ’; 1ơ 1^paratypes, ‘Brit. E. Africa. / Mogorr R. [Mogorro = Migori, 00°59'S: 34°15'E] / May 1913. / A. O.

Notes: I have not seen all the type specimens. Those listed by Oldroyd (1940), but not included in the material sent for study, were (as listed by Oldroyd): ‘ Type ơ BRITISH EAST AFRICA [ KENYA]: Kenyamkago [?], Kisumu [Populated place, 00°06'S: 34°45'E] Province (Dr, J. Pugh). Paratypes BRITISH EAST AFRICA: 2ơ Kaja [Stream, 00°01'S: 37°48'E] Valley, S. Kavirondo [Bay, 00°15'S: 34°35'E], 4000 ft., 31.iv.-1.v.1911 (S. A. Neave) ’.

Distribution and biology: Known only from the type series, all from Kenya. Specimens were collected in February, April and May (Table 1).
