Epimetopus burruyacu Oliva, 1986: 7 .

Type material: Holotype (male): " ARGENTINA, Prov. Tucuman, Dpto. Burruyacú rio Salas 12.II.1982 Leg. R. Golbach; Epimetopus burruyacu A. Oliva 1984 ; HOLOTYPO; aedeagus drawn by P. D. Perkins; DIGITAL IMAGE captured 2012, P. D. Perkins " ( MACN).

Differential diagnosis. The habitus ( Fig. 68) is similar to that of several species in the Costatus group; reliable determinations will be based on examination of the male genitalia. The aedeagus is somewhat similar in general to that of E. angustus ( Figs. 28, 72); both have slender, slightly arching parameres. E. burruyacu differs from E. angustus in that the parameres are shorter compared with the length of the basal piece; also, the median lobe is wider and shorter. Externally, E. burruyacu is larger that E. angustus (ca. 1.55 vs. 1.31 mm), has the elytral carinae and pronotal sculpture slightly less developed, and has smaller elytral punctures ( Figs. 24, 68).

Description. Size: holotype (length/width, mm): body (length from anterior margin of pronotum to elytral apices) 1.55/0.78; head (width) 0.41; pronotum 0.55/0.56; elytra 1.00/0.78. Habitus and sculpture as illustrated ( Fig. 68). Head piceous, dorsum red, venter and coxae dark brown, maxillary palpi testaceous. Eye with ca. 3–4 facets between canthus and posterior margin. Protibiae slightly arcuate. Elytral granules linking punctures. Metaventral depression moderately deep, ca. six granules along base.

Distribution. Currently known from two narrowly separated localities in Argentina ( Fig. 126).
