Remarks.

This species was only known from males collected at elevations above 1100 m in Mt. Humboldt ( Heller 1916) and since its description the only additional record of the species was yet another male collected near the summit of Mt. Kouakoué, also in the Massif du Sud, not far from Mt. Humboldt ( Gómez-Zurita 2011). This specimen provided DNA sequences for phylogenetic analyses, which demonstrated the evolutionary proximity of this species to C. montana ( Papadopoulou et al. 2013; Platania et al. 2024). Here, we report a large number of specimens from several localities in southern parts of the Massif du Sud. This series includes females for the first time, which revealed, as expected, a typical spermatheca of Cazeresia , thus supporting the phylogenetic conclusions and the new combination, Cazeresia humboldtiana ( Heller, 1916) comb. nov. Spermatheca (Fig. 1 x View Figure 1 ) with cornu shorter than nodulus, bent more or less at right angle relative to nodulus; nodulus bulbous basally, with short protruding insertion of spermathecal gland submedially, opposite to cornu; spermathecal duct thin, inserted laterally near base of nodulus, oriented opposite to cornu, about as long or slightly longer than nodulus, forming characteristic bow before gradual enlargement with one complete, elongate coil. The penis of C. humboldtiana (Fig. 7 a View Figure 7 ) was described by Gómez-Zurita (2011).

Distribution.

The species can be considered at present distributed in several areas of relatively high elevation (from 670 m to 1100 m a. s. l.) in the central part of the Massif du Sud (Fig. 8 d View Figure 8 ).
