Scale bar = 100 km. See text for exact localities. + + + + +Distribution +. + +Arcopotamonautes ngae + + +n. sp. + +is known only from one locality in the Kwebuyu River in the Nguu Mountains ( +863 m +ASL) in the +Tanga Region +of northeastern +Tanzania +( +Fig. 11 +). The relatively small Nguu Mountains (area +1,591 km +2 +that reach up to +1,550 m +ASL) are part of a series of forested highlands in the central Eastern Arc mountains that also includes the nearby Mkungwe, Nguru, Ukaguru, Rubeho, and Uvidunda Mountains. + + +Habitat. +This species is found in the Kwebuyu River that drains the forested Nguu Mountains in Handeni District in +Tanzania +. The collection locality in the Kwebuyu River in the forested Nguu Mountains at 863 m ASL is a tributary in the watershed of the Wami River that drains east to the Indian Ocean. The Nguu Mountains are a protected site listed as a Key Biodiversity Area of international significance because they meet established criteria for recognition as a site of biodiversity importance. + + + + +Remarks. +The genus + +Arcopotamonautes +Bott, 1955 + +currently comprises 15 species from the D. R. +Congo +, +Kenya +, +Malawi +, +Rwanda +, +Tanzania +, and +Zambia +( +Cumberlidge & Daniels 2022 +). + +Arcopotamonautes parekeeae + + +n. sp. + +and + +A. ngae + + +n. sp. + +are assigned to this genus because they conform to the diagnosis provided by +Cumberlidge & Daniels (2022: 1291) +. For example, in both species the postfrontal crest is distinct and completely traverses the carapace, the epibranchial tooth is reduced to a small granule, the posterior carapace sulci are distinct ( +Figs. 1A, B +, +6A, B +); and the G1TA is distinctly widened in the midsection and ends in an upturned tip ( +Figs. 4A–C +, +5B, C +, +9A–C +, +10B, C +). + + +Comparisons. + +Arcopotamonautes parekeeae + + +n. sp. + +and + +A. ngae + + +n. sp. + +can be distinguished from + +A. suprasulcatus + +, + +A. xiphoidus +( +Reed & Cumberlidge, 2006 +) + + +A. infravallatus +( +Hilgendorf, 1898 +) + +, and + +A. bellarussus +( +Daniels, Phiri & Bayliss, 2014 +) + +by the form of the G1TA, which is distinctly widened in the midsection in + +A. parekeeae + + +n. sp. + +( +Figs. 4A–C +, +5B, C +) and + +A. ngae + + +n. sp. + +( +Figs. 9A–C +, +10B, C +) (vs slim, curved, and needle-like in + +A. suprasulcatus + +and + +A. bellarussus + +, cf. + +Daniels +et al +. 2014 + +: fig, 5A, B; or cone-shaped, not widened, and tapering to a pointed tip in + +A. xiphoidus + +, cf. +Reed & Cumberlidge 2006 +: figs. 171, 172, and + +A. infravallatus + +, cf. +Reed & Cumberlidge 2006 +: figs. 149, 150). + +Arcopotamonautes parekeeae + + +n. sp. + +and + +A. ngae + + +n. sp. + +can be distinguished from + +A. orbitospinus +( +Cunnington, 1907 +) + +from Lake +Malawi +and + +A. platynotus +( +Cunnington, 1907 +) + +from Lake Tanganyika by the form of the carapace lateral margin which is smooth and lacks teeth in + +A. parekeeae + + +n. sp. + +( +Fig. 1A, B +) and + +A. ngae + + +n. sp. + +( +Fig. 6A, B +) (vs a lateral margin that has several teeth behind the epibranchial tooth in + +A. orbitospinus + +, cf. +Reed & Cumberlidge 2006 +: pl.
