Diagnosis

Diameter 1.41–1.58 mm, 50–53 podous rings ( Fig. 9 View Fig ). Shares a short (as broad as long, or slightly longer) gonopodal palette with A. denticulatus   , A. fasciatus   , A. stereosathe   , A. submajor   , and A. udzungwensis   . Differs from these species, except A. fasciatus   , by the combination of fully developed telopodites on the first pair of male legs, the gonopodal telomere describing a ca 270° curve, curving almost in one plane only, by lacking a spinose lid-like flap on the besal telomeral lamella, and by having a distinct mesobasal lobe of the gonopod palette. Very similar to, and perhaps not distinct from A. fasciatus   , differs by being mostly smaller (male diameter <1.7 mm) and by having the prefemoral processes of the first pair of male legs more slender, finger-shaped.

Descriptive notes

The specimens from Udzungwa Mts National Park very much resemble those from Mt Kilimanjaro (type locality of A. claudiahempae   ), in size ( Fig. 9 View Fig ) as well as in gonopod structure ( Fig. 10 View Fig , cf. Enghoff & Frederiksen 2015: fig. 10). In particular, the two samples agree in having the distal part of the telomere compressed, i.e., instead of forming a gutter, the lamella constituting the telomere is folded flat such that the inside of the gutter becomes invisible; the outside is strongly microspinose on one side and the free margin of the other side is characteristically wavy-spinose ( Fig. 10D View Fig , Enghoff & Frederiksen 2015: fig. 10d).

First pair of male legs ( Fig. 3 View Fig D–I) each with a single, finger-shaped prefemoral process; prefemoral processes more slender than those of the otherwise very similar A. fasciatus   ( Fig. 3 View Fig A–C); setae of telopodite distal to prefemur similar in length to those of normal walking legs.

Distribution

Described from Mt Kilimanjaro (1169–1345 m a.s.l., in habitats disturbed by human activities; Enghoff & Frederiksen 2015); now also known from one site at 650 m a.s.l. in the Udzungwa Mts ( Fig. 1 View Fig ).

Remarks

Enghoff (2016 b) discussed A. fasciatus ( Attems, 1896)   (see below), emphasizing its great similarity with A. claudiahempae   and suggesting that the latter might be a synonym of A. fasciatus   . The similarity between both nominal species also extends to the compressed distal part of the telomere ( Enghoff 2016 b: fig. 7c, f). The only differences between the two seem to be size (cf. the identification key below, couplet 9) and the shape of the prefemoral process of the first pair of legs ( Fig. 3 View Fig ). The new specimens of A. claudiahempae   from Kidatu, Udzungwa Mts are of the same size as A. claudiahempae   from Mt Kilimanjaro ( Fig. 9 View Fig ), and their prefemoral processes strongly resemble those of Kilimanjaro specimens. Aquattuor claudiahempae   and A. fasciatus   are, for the time being, upheld as separate species.
