Fig. 6

Diagnosis

Diameter 1.97–2.11 mm, 53–54 podous rings. Gonopods: lateral incision of coxa (li) triangular, basally delimited by triangular tooth; apical palette (pa) obliquely rounded, much longer than broad; telomere describing an almost 360° curve in almost one plane; mesal-posterior lamella of telomere (mpl) low; anterior margin of telomere with a triangular tooth (tt); telomere tip with densely microspiculate margins and internal surface.

Etymology

The name is a Latin adjective meaning “larger” and refers of the larger size of this species, compared to its congeners.

Material studied (total: 4 ♂♂)

Holotype

TANZANIA: ♂, Morogoro Region, Udzungwa Mts , Mwanihana FR, 1800–1850 m asl, 25–29 Nov. 1984, pitfall traps, montane rain forest, N. Scharff leg. ( ZMUC).

Paratypes

TANZANIA: 3 ♂♂, Morogoro Region, Udzungwa Mts, Mwanihana FR, above Sanje, 1650 m asl, 18 Aug. 1982, pitfall trap, M. Stoltze & N. Scharff leg. (ZMUC).

Type locality

TANZANIA: Morogoro Region, Udzungwa Mts, Mwanihana FR, 1800–1850 m asl, montane rain forest.

Colouration

After 31–33 years in alcohol faded, only some darker markings on head and collum left. No traces of a mid-dorsal stripe.

Distribution and habitat

Known only from Mwanihana FR. Altitudinal range: 1650–1850 m asl. Habitat: montane rain forest.

Coexisting species

Aquattuor submajor Enghoff sp. nov. and Chaleponcus mwanihanensis Enghoff, 2014 occur in the same area, the former, however, only at lower altitudes.
