(ZMUM), 1 &amp;male; (ZMUC), 1 &amp;male; (NMNHS), 1 &amp;male; (MCSNV). <b>Name.</b> To emphasize the broad paraterga. <b>Diagnosis.</b> Differs from all congeners except <i>E. similis</i> sp. n. by the very broad and mostly only slightly declivous paraterga, such that volvation is apparently imperfect, from <i>E. similis</i> sp. n. by the collum bearing no row of peculiar teeth along its entire front margin, and the gonopods being less enlarged and simpler distally. <b>Description.</b> Length of adults of both sexes <i>ca</i> 11-13 mm, width 2.4-3.0 mm, body broadest at segments 5-16. Holotype <i>ca</i> 12 mm long and 3.0 mm wide. Coloration uniformly yellow-brown to brownish, sometimes slightly marbled. Adults with 20 segments (Fig. 14A), conglobation pattern typical of “ Doratodesmidae ”, but volvation apparently imperfect because of paraterga being too broad and mostly only slightly declivous, leaving small lacunae laterally even when body maximally enrolled. Head (Figs 14F; 15A) and tegument (Figs 15E, F) basically as in preceding species, but antennae somewhat longer, antennomeres 3 and 6 of subequal length (Fig. 14F), collum not covering the head from above, slightly elevated frontolaterally, with 4-5 irregular rows of mostly flat tubercles/bosses, including a row of more distinct cones at caudal edge (Figs 15A, B). Metaterga behind collum with three transverse, rather irregular rows of similarly flat tubercles, most of which still retain short, bisegmented setae (Fig. 15A, B, D-F); limbus microcrenulate. Paraterga with evident shoulders anteriorly, mostly directed laterad, only slightly declivous, very broad, tips about level with venter, very distinctly crenulate caudolaterally (Figs 14 A-E; 15C, D); paraterga 2 rather strongly enlarged, directed ventrolaterad, lateral margin evidently quadrilobulate, both schism and hyposchism small; paraterga 3 and 4 slightly shorter than others, bilobate laterally (Figs 14B; 15B), following paraterga more broadly rounded and quadrilobulate, overlap typical. Pore formula normal, ozopores located at base of ventrocaudal lobulation (Fig. 15D). Pleurotergal carinae wanting. Epiproct strongly flattened, dorsally also tuberculate, with several deep incisions at lateral edge, directed ventrocaudad, with the usual four cones just below tip; para- and hypoprocts as in Figs 14 C-E. Sterna usually with a rather deep, narrow depression between coxae (Fig. 16A), only those between coxae 7 and 9 much wider (Fig. 16B). Gonopod aperture transverse-oval, relatively small, far from reaching lateral sides of segment 7 (Fig. 16B). Legs very long and slender; femur somewhat longer than tarsus; several basal segments in &amp;male; microtuberculate; claw simple, very slightly curved ventrad; some setae very sparsely microdenticulate (Figs 14F; 15C; 17A). Gonopods (Figs 16 B-E; 17B, C) very simple. Coxae subquadrate, large, microtuberculate and abundantly setose ventrolaterally, with a conspicuous triangular lobe frontolaterally. Telopodite considerably longer than coxite, slender, setose not only in its basal half but also at base of a digitiform and conspicuously microtuberculate distofemoral process (dp) situated laterally at about midway of telopodite, more distally with a slightly folded acropodite devoid of a hairpad; seminal groove terminating subapically. <b>Remarks.</b> This species seems to be especially close to the next species.
