Epimetopus , aedeagi of holotypes. Differential Diagnosis. The dorsal habitus of E. multiportus ( Fig. 102 ) is very similar to that of other members of the Plaumanni group. Males have the clypeus upturned, as do E. vianai and E. vulpinus . Examination of the male genitalia will be essential for reliable determinations. The aedeagus ( Fig. 106 ) is smaller than that of other members of the species group (ca. 0.66 vs. 0.76 mm ), and the apices of the dorsal processes fit into indentations in the median lobe, a character not seen in the other species. Description . Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 2.30/1.13; head (width) 0.59; pronotum 0.80/0.85; elytra 1.48/1.13. Habitus as illustrated ( Fig. 102 ). Head piceous, maxillary palpi light brown; pronotum dark brown to piceous; elytra dark brown except yellowish, large V-shaped fascia near midlength, and at apical ¼ of elytra; venter and coxae piceous, remainder of legs dark brown. Pronotum with hood carinae very slightly arcuate, converging and confluent anteriorly, grooved throughout; secondary lateral very small, almost absent. Elytron with four strong granulate carinae, third interrupted anteriorly for distance of ca. 3 punctures; punctures round or oval, large, each with small granule at anterior margin, non-carinate intervals without granules. Protibiae with inner margin straight, outer arcuate. Metaventral depression moderately deep, ca. seven granules along base. Distribution. Currently known from Paraguay and Uruguay ( Fig. 127 ). Etymology. Named in reference to the transparent, porthole-like elytral punctures.
