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.


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.

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. 7CView 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 –BView Fig. 6).

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

GONOPODS ( Fig. 16View 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.
