Mislocatus ealensis ( Vanschuytbroeck, 1951)

Material studied: 1 male paratype: 1) Congo-belge, Eala— 24-V-1935, J. Ghesquière, 527; 2) P. Vanschuytbroeck det. 1951 “ Ceroptera ealensis Vansch. ” [Vanschuytbroeck’s handwriting]; 3) [red] Para-type; 4) cf. Bull. Inst. Sc. Nat. Belg. “T. XXVII, no. 33, 1951, p. 11”. 1 male ( BMSA) 1 female ( HNHM, abdomen and genitalia prepared and kept in a plastic microvial with glycerol): Malaise traps, broad-leafed deciduous woodland—RSA, KZN, Ndumi Game R., main camp at: 26° 54.652’ S, 32° 19.719’ E, 27–30.xi.2009, A. H. Kirk-Spriggs.

Description. Measurements in mm: body length 1.26 (paratype male), 1.20 (male), 1.47 mm (female), wing length 1.23 (paratype male), 1.10 (male), 1.32 mm (female), wing width 0.54, 0.52, 0.66 (female).

Legs (see Papp 2008, p. 62). Mid tibia with 2 antero-dorsals at 5/16 and 3/4, 1 dorsal seta at 13/16, 1 posterodorsal at 25/32, i.e. slightly distal to distal 3/4 of tibia.

Wing membrane greyish yellow, all veins ochreous. Fringe on the first section of costal vein not much longer than on its second section 0.03–0.032 mm). Second costal section much shorter than third (0.29 mm vs 0.60 mm). Costal vein long overruns apex of R4+5. Vein R4+5 concave, apex slightly bent up. Intra-crossvein of M1+2 0.14 mm, M-M crossvein 0.11 mm. Lower edge of discal cell slightly more than 90. M1+2 although faint, traceable to wing margin. M3+4 appendage longer than crossvein. Anal vein lengthened to the level of R-M. Alula small and narrow.

Female. Abdominal tergite 1+2 0.25 long, tergite 2 0.40 mm long, longest marginal setae on tergite 2 0.17– 0.18 mm, 8–9 such long setae present. Tergite 3 0.26–0.27 mm broad, also weakly sclerotised, appearing bipartite, trapezoid in all. Tergite 4 0.20 * 0.10 mm with a pair of 0.08 mm long marginal setae. Sternites broad, setae sparse (e.g. only 6 long marginal caudal setae on sternite 4), membrane between tergites and sternites with long setae. Epandrium with at least 5 very long lateral pairs of setae, up to 0.12 mm.

Remarks. Although only 1 species in the new genus Mislocatus is known at present, I think, the shape and the number of pegs on its process of male sternite 5, the shape of cercus, the shape and armature of surstylus, the shape of postgonite are characteristic for a species only. That is, if one finds a second species, we may expect different shapes and setae in those structures. I described them in the characterisation of the genus, but I would stress only those features which permit a safe separation from the related genera.
