Diagnosis Differs from other species of the E. kwabuniensegroup by having the solenophore almost as long as mapand iap, which are both smooth, in combination with the equal length of the three apical lobes of the solenophore.
Etymology The name is an adjective referring to the equally long apical lobes of the solenophore.
Material studied(total: 1 ♂) Holotype TANZANIA: ♂, Iringa Region, Iringa District, New Dabaga/ Ulangambi FR, 08°04′05.6″ S, 35°54′20.41″ E, montane, 1930 ma.s.l., Plot 6, 29 Oct.2000, Frontier Tanzanialeg. ( ZMUC).
Description(male) SIZE. Length not measurable, hind end of unique specimen missing; max. width 1.7 mm. COLOUR. Completely pallid after 17 years in alcohol, possibly not due to fading, cf. remarks under E. ottokrausi sp. nov. ANTENNAE. Reaching back to end of ring 4. BODY RINGS. Paranota completely absent. Stricturebetween pro- and metazonite not striolate. Apair of dorsal setae on body ring 2, other rings apparently naked. TELSON. Missing from specimen. Fig. 11. Eviulisoma aequilobatum sp. nov., holotype, right gonopod. A. Mesal view. B. Lateral view. C. Ventral view. D. Tip of solenophore, sublateral view. E. Dorsal view. 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–C, E = 0.1 mm; D = 0.05 mm. LEGS. Length 1.2× body width. Relative lengths of podomeres: femur> prefemur = tarsus> tibia> postfemur. Scopulae on femur, postfemur, tibia and tarsus, hardly diminished on body ring 11 (last ring present on specimen). STERNUM 5. Atrapezoid process between legs 4. STERNUM 6. Deeply excavated. Rim or margin simple. GONOPODS ( Fig. 11). Coxal lobe ( cxl) large. Prefemoral part ( prf) ca half as long as acropodite. Mesal acropodital process ( map) long, slender, slightly arched, apically expanded, somewhat axe-shaped. Intermediate acropodital process ( iap) as long as map, basally stouter than mapbut apically tapering to pointed tip, smooth except for slight rugosities on distal part. Solenophore ( sph) large, almost as long as map,folded around solenomere ( slm), three-lobed, all lobes of equal length, but dorsal and ventral lobes ( sph-dand sph-v) stouter, finger-shaped, intermediate lobe ( sph-i) tapering to long pointed tip.
