Figs. 119 (habitus), 122 (aedeagus), 126 (map)

Type Material. Holotype (male): Brazil: Mato Grosso, São Felix , 11° 37' S, 50° 40' W, 1–30 vi 1961, M. Alvarenga ( MSP) . Paratype: Brazil: Mato Grosso, Barra do Tapirapé , 10° 50' S, 50° 40' W, 1–30 xi 1964, B. Malkin (1 MSP) .

Differential Diagnosis. Habitus similar to that of E. deceptus ( Figs. 113, 119); differing therefrom in the smaller and denser pronotal tubercles, the larger denticles on the anterior angles of the elytra, and the larger size (ca. 3.59 v. 2.73 mm). The aedeagi of the two species are marked dissimilar ( Figs. 114, 122). The aedeagus can perhaps be compared with that of E. tridens ( Fig. 123); they have a similar general plan, but differ markedly in proportions. In E. fimbriatus the median lobe is much wider, as are the parameres and the basal piece; also, the dorsal processes of the median lobe are located more proximally, and the basal piece is markedly more arcuate. The habitus of E. fimbriatus and E. tridens are markedly dissimilar ( Figs. 118, 119).

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 3.59/1.79; head (width) 0.94; pronotum 1.18/1.50; elytra 2.50/1.79. Habitus as illustrated ( Fig. 119). Head dark brown to piceous, maxillary palpi light brown; dorsum dark brown with lighter fascia at about midlength of elytra; venter and coxae dark reddish brown, remainder of legs ochraceous. Pronotum with hood carinae straight, converging and well separated anteriorly; secondary lateral lobe moderately large; sometimes with smaller, third lobe near base. Elytron with four strong granulate carinae, third interrupted anteriorly for distance of ca. 3–4 punctures; punctures round or oval, large, each with small granule at anterior margin, non-carinate intervals without granules. Protibiae slightly emarginate on inner margin, outer margin arcuate. Metaventral depression moderately deep and wide, ca. eight large granules along base.

Etymology. Named in reference to the fimbriate lateral margins of the pronotum and anterior angles of the elytra. Distribution. Currently known only from Mato Grosso, Brazil ( Fig. 126).
