Diagnosis

Differs from other species of the E. kwabuniense group by map being apically shaped like a narrow, slightly hooked spoon and at ca ¾ of its length having a side branch, in combination with a spinose iap and a solenophore with a large, hooked dorsal lobe.

Etymology

The species name honours the European Journal of Taxonomy ( EJT), in recognition of its immense importance for the dissemination of taxonomic research in Europe, and beyond.

Material studied (total: 5 ♂♂)

Holotype TANZANIA: ♂, Iringa District, Udzungwa Scarp FR, 11 km SE of Masisiwe Village, Kihanga Stream , 1800 m a.s.l., 08°22′05.7″ S, 35°58′41.6″ E, 17–27 May 1997, ZMUC and SI Exp. leg. ( ZMUC). GoogleMaps

Referred non-type material

TANZANIA: 1 ♀, tentatively referred to this species, same collection data as for holotype ( ZMUC).

Description (male)

SIZE. Length 15 mm, max. width 1.5 mm.

COLOUR. After 20 years in alcohol uniformly light yellowish brown, a little darker dorsally.

ANTENNAE. Reaching back to middle of ring 3.

BODY RINGS. Paranota completely absent. Stricture between pro- and metazonite clearly striolate. A transverse row of setae on all body rings, but many setae abraded.

HYPOPROCT. Large, trapezoid, almost rectangular, with three prominent marginal tubercles.

LEGS. Length = body width. Relative lengths of podomeres: prefemur = femur> tarsus> tibia> postfemur. Scopulae ( Fig. 7C View Fig. 7 ) on femur, postfemur, tibia and tarsus, present until last pair of legs, although less dense posteriorly.

STERNUM 5. A trapezoid process, slanting anteriad, between legs 4 ( Fig. 6 A –B View Fig. 6 ).

STERNUM 6. Deeply excavated. Rim of excavation simple ( Fig. 6 A –B View Fig. 6 ).

GONOPODS ( Fig. 16 View Fig. 16 ). Coxal lobe ( cxl) prominent. Prefemoral part ( prf) ca 0.4× as long as acropodite. Mesal acropodital process ( map) stout, straight, apically divided into long, narrowly spoon-shaped, slightly hooked branch and short, rounded-triangular side branch. Intermediate acropodital process ( iap) almost as long as map, very slender, straight, densely spinose. Solenophore ( sph) very large, ca 0.8× as long as map, deeply divided into relatively broad, mesally concave, apically hooked dorsal process ( sph-d) and much shorter, long, lamelloid ventral process ( sph-v), a very short lamelloid process between sph-d and sph-v.

Distribution and habitat

Known only from the Udzungwa Scarp FR, 11 km SE of Masisiwe Village, Kihanga Stream, 1800 m a.s.l.
