Octavius ruthae Janák, 2007: 200

Type locality. South Africa, Eastern Cape, Mbotyi Forest.

Material examined. SOUTH AFRICA: EASTERN CAPE: Transkei, Ntsubane Forest Station , 31.27 S – 29.44 E, indigenous forest litter, 25.xi.1977, E-Y: 2537, leg. Endrödy-Younga, 593373 ♀♀ ( TMSA, JJRC) ; same data, but: forest floor litter, 6.xii.1988, E-Y: 2599, 73326 ♀♀ ( TMSA, JJRC) ; same data, but: fungous logs, 6.xii.1988, E-Y: 2600, 13( JJRC) ; same data, but: forest floor litter, 25.xi.1988, E-Y: 2579, 393340 ♀♀ ( TMSA, JJRC) ; same data, but: 24.xi.1988, rotten Cussonia fruit, E-Y: 2577, 43 ( TMSA) .

Variability. Aedeagus of the studied specimens is identical with types (see Fig. 8 in JANÁK 2007). Median impressions on the disc of the head is very shallow and rounded, not longitudinal as in O. rostrifer Puthz, 1968 or O. ndumu sp. nov. For this reason, O. ruthae should be placed in the key in the proximity of O. microps ( Kistner, 1967) and not of O. rostrifer Puthz, 1986 , as previously done by JANÁK (2007).

Distribution. Octavius ruthae has been recorded only from Mbotyi and Ntsubane Forest.
