Type Material. Holotype (male): Uruguay: 90 km SW Artigas, 31° 1' S, 57° 52' W, 27–30 ix 2001, R. Linek ( NMW) GoogleMaps   . Paratypes (32): Paraguay: Dep. Concepcion, Arroyo Toro Paso, Unterlauf (contrib. Rio Apa ), seepage, 23° 51' S, 56° 46' W, 24 x 2002, U. Drechsel (19 NMW) GoogleMaps   ; Uruguay: 90 km SW Artigas, 31° 1' S, 57° 52' W, 27–30 ix 2001, R. Linek (13 NMW) GoogleMaps   .

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.
