(Figs 39–53)
Type material. Holotype male (HNHM, abdomen and genitalia prepared and kept in a plastic microvial with glycerol, right wing prepared on a slide): CONGO: Brazzaville, ORSTOM park, J. Balogh & A. Zicsi, soil traps in forest— 2. I. 1964. 10 days, No. 572.
Paratype female (HNHM): same as for holotype.
Description. Measurements in mm: body length 1.06 (holotype), 1.12 (paratype), wing length 1.02 (holotype), c. 1.03 (paratype); wing width 0.45 (holotype), 0.47 (paratype). Body microtrichose (tomentose) brown (i.e. not shiny).
Head. Eye rather small, longitudinal axis oblique, 0.15 mm long. Gena 0.07 mm below eye. Two long frontoorbital setae. 4 medium-long interfrontal setae. Inner vertical seta very long, outer vertical seta rather long (0.10 mm) and thick. Both inner and outer occipital setae distinct. Genal seta short, upcurved. Scape seta 0.06 mm long. First flagellomere with a narrowly rounded dorsal apex. Arista dorsal subapical in position, 0.29 mm long, i.e. very long compared to body dimensions; with fine (0.015 mm) cilia.
Thorax. Only 1 prescutellar dorsocentral seta, 0.175 mm long. Prescutellar acrostichal seta only 0.05–0.055 mm. Acrostichal setulae sparse but comparatively long. Anepisternum bare. Katepisternum with a single posterior seta of 0.13 mm.
Wing. Costal vein thickened, thickness on second section slightly more than 0.02 mm. Sub-basal seta of costa 0.09–0.10 mm, its inner pair distinctly shorter (0.07 mm). Setae on first costal section long, 0.05 mm. Second costal section slightly shorter than third (0.27 mm vs 0.295 mm). Costa ends 0.07 mm before wing apex. Vein R4+5 strongly bent up, costa terminates at its apex. Inter-crossvein section of M1+2 0.125, M-M crossvein 0.06 mm. Alula small, apex narrowly rounded. Halter pale yellow (but probably discoloured in alcohol).
Legs. Mid tibia with a distinct mid ventral seta. Mid tibial armature: anterodorsals at 7/25, 23/50 and 18/25 (the strongest), a dorsal seta at 11/25, a strong posterodorsal at 19/25. Mid basitarsus with sparse but long anteroventral and posteroventral rows. Hind basitarsus 0.10 mm, second tarsomere 0.12 mm long.
Male. Fore claws modified: outer claw much enlarged (Fig. 49), inner claw long thin but normal. Lower apical margin of surstylus with fine serration. Distiphallus with a large ventral Y-shaped sclerite and a blunt dorsal part, cordiform in caudal view.
Female. As male, but fore claws normal, though longer than on mid and hind tarsi. Female preabdominal tergites quite normal. Sternite 2 more than 3 times (10/3) broader than long. Width of female tergites vs sternites (width/length): 3rd 24/10, 4the 24/12, 5th 26/10, 6th 25/7. Tergite 6 with sparse medially long setae, which are not longer than caudal ones. Tergite 7 not divided at all. Sternite 8 with apex dorsally curved, sagittally impressed. Female genitalia form a hollow, where tergite 8 and sternite 8 are in the most caudal parts (Fig. 50). Epiproct with cerci and hypoproct slightly upcurved. Dorsal wall of egg-tube with 2 small short horizontal platelets (apices rather caudal to that of the hypoproct). Spermathecae (Fig. 53).
Etymology. I named this new species after the late Professor JÁNOS BALOGH, the famous acarologist, who collected the type specimens and many other invaluable specimens of Sphaeroceridae (some others are described also in the present paper).
