description
Description (male) SIZE. Length 14 mm, max. width 1.5 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 3. BODY RINGS. Paranota completely absent. Stricture between pro- and metazonite striolate. A transverse row of setae on pre-gonopodal rings, a few scattered setae seen on post-gonopodal rings. HYPOPROCT. Trapeziform with three apical tubercles. LEGS. Stout, short, length 0.9 × body width. Relative lengths of podomeres: femur = prefemur> tarsus> postfemur = tibia. Scopulae on femur, postfemur, tibia and tarsus, continuing until last legs, except on femur. STERNUM 5. A rounded-rectangular process between legs 4. STERNUM 6. Deeply excavated. Rim of excavation simple. GONOPODS (Fig. 15). Coxal lobe (cxl) large. Prefemoral part (prf) ca half as long as acropodite. Mesal and intermediate acropodital processes (map and iap) largely identical, slender, smooth, pointed rods. Solenophore (sph) large, ca 0.8 × as long as acropodital processes, folded around solenomere (slm), three-lobed, dorsal and ventral lobes (sph-d and sph-v) finger-shaped, much longer than pointedtriangular intermediate lobe (sph-i).

diagnosis
Diagnosis Differs from other species of the E. kwabuniense group by having the solenophore somewhat shorter than the smooth map and iap, in combination with the small size of the intermediate apical lobe of the solenophore, compared with the very long, slender dorsal and ventral lobes.
distribution
Distribution and habitat Known only from the New Dabaga / Ulangambi FR. Altitude 1800 – 1900 m a. s. l.
etymology
Etymology The name is a noun in apposition, referring to the one short and two long apical lobes of the solenophore. Commelina L. is a genus of plants (ʻdayflowersʼ) with flowers characterized by one small and two large petals. Linnaeus (1737: 79) dedicated this genus to three members of the family Commelijn, two of whom were well-known botanists, while the third accomplished nothing (at least not in botany); see also Wijnand (1983: 11).
