Diagnosis
Differs from other species of the E. kwabuniense group by having the solenophore two-lobed, its dorsal lobe developed as a very strong hook, hook much larger than those seen in certain other species (E. ejti sp. nov., E.akkariae sp. nov., E. nessiteras sp. nov.).
Etymology
The species name honours CETAF, Consortium of European Taxonomic Facilities, www.cetaf.org, in recognition of the immense importance of CETAF for natural history collections in Europe and for collections-based research.
Material studied (total: 12 ♂♂)

Description (male)
SIZE. Length 20 mm, max. width 1.9–2.1 mm.
COLOUR. After 33 years in alcohol all whitish.
ANTENNAE. Reaching back to middle of ring 3.
BODY RINGS. Paranota indicated by very faint ridges on body ring 2 (as in Fig. 4C), otherwise completely absent. Stricture between pro- and metazonite not striolate. A transverse row of setae on all body rings, but the majority of setae abraded in most specimens.
HYPOPROCT. Large, trapezoid, with three prominent apical tubercles, middle tubercle larger.
LEGS. Length 1.2× body width. Relative lengths of podomeres: femur> prefemur> tarsus> tibia> postfemur. Scopulae (Fig. 7B, D) on femur, postfemur, tibia and tarsus until ca midbody, thereafter gradually disappearing.
STERNUM 5. A small trapezoid process between legs 4.
STERNUM 6. Deeply excavated. Rim of excavation simple.
GONOPODS (Fig. 13). Coxal lobe (cxl) moderate. Prefemoral part (prf) ca half as long as acropodite. Mesal acropodital process (map) a long, smooth, almost straight rod, apically pointed, subapically with small triangular side branch. Intermediate acropodital process (iap) a very slender, straight rod, densely covered in long spines on part of its surface, especially on apical part (Fig. E). Solenophore (sph) deeply split into two long lobes; dorsal lobe (sph-d) a very large, strong hook, almost reaching to tip of acropodital processes; ventral lobe (sph-v) much shorter, lanceolate; no intermediate process between sph-d and sph-v; internal surface of sph with a ridged area (ra, Fig. 13D, F).
Distribution and habitat
Known only from the Udzungwa Scarp FR. Altitudinal range 1300–1550 m a.s.l. Habitat: montane rain forest. Collected together with E. chitense sp. nov.
