5C11879EFFB5FFDEFD84EF7DFDF610CB.taxon	diagnosis	Diagnosis (modified after Enghoff & Frederiksen 2015) Differs from all other Odontopygidae by the structure of the limbus, which consists of large, rectangular, easily detachable flaps. Gonopods of the Prionopetalini type, i. e., basomere of telopodite with a torsate flexible zone followed by a posttorsal narrowing; solenomere elongated. Gonopodal proplica apically expanded into a distal palette; metaplica with an oblique flange; solenomere simple, thin and whip-like; telomere terminating in a long, curved, gutter-like to tubular part. Descriptive notes For characters not mentioned here, see Enghoff & Frederiksen (2015). Mandibular stipes (Fig. 2): in males, but not in females with a disto-ventral expansion. First pair of male legs: in the genus Aquattuor the first pair of legs is remarkably diverse. Figs 3 – 7 illustrate the first pair of legs in all known species of the genus, with a focus on the prefemur. In all of them, the prefemur carries a more or less finger-shaped process (pfp) which projects orad from the anterior surface of the prefemur (Figs 3 – 7). The distal (ventral) surface of the process is smooth, the basal (dorsal) surface is more or less scaly-rugose. The shape of the process varies from slender fingershaped to relatively broad / triangular, and in one species (A. nguruensis sp. nov.) there is a clearly delimited depression (pfd) on the distal surface of the process (Fig. 4 A – C). In A. major Enghoff, 2015, A. longipala Enghoff, 2015 and A. mollilobus sp. nov. there is in addition a second, more distal, more irregularly shaped prefemoral lobe (dpl, Figs 5 – 6). Another type of variation is seen in the setation of the telopodites of the first pair of legs (Fig. 8). Here, A. mollilobus sp. nov. (Fig. 8 C) stands out by having very short setae on all podomeres. Aquattuor major and A. longipala have long setae on the tarsus, but very short ones on the femur (Fig. 8 B). The remaining species have long setae (same length as on the following leg-pairs) on all podomeres (Fig. 8 A). These differences in setation do not seem to reflect the setation of normal walking legs. In one species (A. udzungwensis), the podomeres distal to the prefemur of the first leg pair seem to be invariably missing (several specimens examined) (Fig. 7 D – E). Adhesive pads on walking legs are absent.

5C11879EFFB2FFD0FE0DE875FAB01676.taxon	diagnosis	Diagnosis Diameter 1.41 – 1.58 mm, 50 – 53 podous rings (Fig. 9). 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. Material studied (total: 25 ♂♂, 29 ♀♀) TANZANIA • 1 ♂, paratype; Kilimanjaro Region, Mt Kilimanjaro, Hai District; 03 ° 13 ′ 59.37 ″ S, 37 ° 16 ′ 09.28 ″ E; 1345 m a. s. l.; 20 Nov. 2013; S. B.

Malumbres-Olarte leg.; pitfall trapping (summed catch from eight traps); NHMD 621639. 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) as well as in gonopod structure (Fig. 10, 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. 10 D, Enghoff & Frederiksen 2015: fig. 10 d). First pair of male legs (Fig. 3 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 A – C); setae of telopodite distal to prefemur similar in length to those of normal walking legs.	en	Enghoff, Henrik (2020): A mountain of millipedes VIII.

5C11879EFFB2FFD0FE0DE875FAB01676.taxon	discussion	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. 7 c, 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). The new specimens of A. claudiahempae from Kidatu, Udzungwa Mts are of the same size as A. claudiahempae from Mt Kilimanjaro (Fig. 9), and their prefemoral processes strongly resemble those of Kilimanjaro specimens. Aquattuor claudiahempae and A. fasciatus are, for the time being, upheld as separate species.	en	Enghoff, Henrik (2020): A mountain of millipedes VIII.

5C11879EFFA1FFC1FDEAEA60FAFE156F.taxon	discussion	Remarks – The distinction between A. submajor and A. udzungwensis The distinction between A. udzungwensis and A. submajor according to Enghoff & Frederiksen (2015) is quite subtle. The newly studied material has contributed to a better understanding of the differences between these two species. Among the differences stated by Enghoff & Frederiksen (2015), the shape of the meso-posterior lamella of the telomere seems to be the only reliable one (Figs 16 – 17). The mesoposterior lamella is high and basally angled in A. udzungwensis, and towards the tip of the telomere, the lamella narrows gradually. In A. submajor, the lamella is lower, not angled, and not narrowing so strongly towards the tip. However, two new clear differences can now be added: • The basal telomeral lamella (btl) in A. udzungwensis has a small, spinose, lid-like flap (spl) (Fig. 17); such a flap is absent in A. submajor (Fig. 16). • In all dissected males of A. udzungwensis (> 10), collected in several parts of the Udzungwa Mts, the telopodites of the first leg-pair are strongly reduced distal to the prefemur (Fig. 7 D – E). Only tiny, somewhat irregular and darkened remnants are present, suggesting that their absence may be due to some physical damage inflicted on the male. In all examined males of A. submajor, the telopodites are normal (Fig. 7 A – C). For both species, the newly studied material considerably widens their size range: newly studied specimens of A. submajor have fewer podous rings and a smaller body diameter than those studied by Enghoff & Frederiksen (2015); in A. udzungwensis the newly studied specimens tend to have more podous rings than those previously studied, while there is a marked difference in diameter. These differences may, at least in part, be correlated with altitude: both species show a clear decrease of numbers of podous rings with increasing altitude from mostly> 50 podous rings at 600 – 900 m altitude to <46 rings at 1400 – 1550 m altitude (Fig. 18).	en	Enghoff, Henrik (2020): A mountain of millipedes VIII.
