A mountain of millipedes VII: The genus Eviulisoma Silvestri, 1910, in the Udzungwa Mountains, Tanzania, and related species from other Eastern Arc Mountains. With notes on Eoseviulisoma Brolemann, 1920, and Suohelisoma Hoffman, 1963 (Diplopoda, Polydesmida, Paradoxosomatidae) Enghoff, Henrik European Journal of Taxonomy 2018 2018-06-19 445 1 90 3DHSS Enghoff, 2018 Enghoff 2018 [623,866,1023,1050] Diplopoda Paradoxosomatidae Eviulisoma GBIF Animalia Polydesmida 29 30 Arthropoda species chitense sp. nov.   Figs 6D, 14    Diagnosis Differs from other species of the  E. kwabuniensegroup by the combination of a mapwith a short subapical laterad side branch, a partly spinose iap, and a clearly three-lobed solenophore that is much shorter than mapand iap, dorsal lobe of solenophore much longer than the others.    Etymology The name is an adjective referring to the typelocality.   Material studied(total: 5 ♂♂)  Holotype   TANZANIA: ♂, Iringa Region, Udzungwa Scarp FR, above Chita Village,  1400 ma.s.l.,  4–5 Nov. 1984, pitfall trapsin montane rain forest, N. Scharffleg. ( ZMUC).   Paratypes   TANZANIA: 4 ♂♂, same locality as for holotypebut  1050 ma.s.l.,  26–29 Oct. 1984, pitfall trapsin intermediate rain forest, N. Scharffleg. ( ZMUC).  Description(male) SIZE. Length 20 mm, max. width 1.6–1.9 mm. COLOUR. After 33 years in alcohol whitish to very light brown, a little darker dorsally. ANTENNAE. Reaching back to middle of ring 4.   Fig. 14.  Eviulisoma chitense sp. nov.paratype. A, C–F. Left gonopod. A. Lateral view. C. Mesal view. D. Ventral view. E. Dorsal view. F. Isolated solenophore, lateral view. B. Lobe between legs 4. Abbreviations: cxl= coxal lobe; iap= intermediate acropodital process; map= mesal acropodital process; prf= prefemoral part; slm= solenomere; sph-d, sph-i, sph-v= dorsal, intermediate and ventral lobes of solenophore. Scale bars: A–E= 0.1 mm; F = 0.05 mm. BODY RINGS. Paranota indicated by very faint ridges on body ring 2 (as Fig. 4C), otherwise completely absent. Stricturebetween pro- and metazonite smooth. Atransverse row of setae on all body rings. HYPOPROCT. Trapezoid, almost rectangular with three large apical tubercles. LEGS. Length 1.1× body width. Relative lengths of podomeres: femur> prefemur> tarsus> tibia> postfemur. Scopulae on femur, postfemur, tibia and tarsus until midbody, gradually disappearing on more posterior legs. STERNUM 5. Asmall subrectangular lobe between legs 4 ( Fig. 6D). STERNUM 6. Deeply excavated. Rim of excavation simple. GONOPODS ( Fig. 14). Coxal lobe ( cxl) distally right-angled. Prefemoral part ( prf) ca half as long as acropodite. Mesal acropodital process ( map) a straight, smooth rod with a subapical curved side branch. Intermediate acropodital process ( iap) a curved pointed rod, covered in long spines along mesal side. Solenophore ( sph) much shorter than acropodital processes, curving around solenomere ( slm), apically with three slender lobes /processes, dorsal lobe ( sph-d)longer, intermediate process ( sph-i) thinner than the others.    Distribution and habitat Known only from the Udzungwa Scarp FR, above Chita Village. Altitudinal range 1050–1400 ma.s.l. Habitat: intermediate and montane rain forest. Collected together with  E. cetafi sp. nov. 1937470325 1984-11-04 1984-11-05 1984-11-04 ZMUC Udzungwa Scarp FR & N.
