Non-type material (9). ARGENTINA. Formosa: Laguna Yema: Centro de Validación-(CEDEVA), barrio CEDEVA, 24º16’03’’S 61º14’54’’W, 163 m, 14.XII.2008, F.C. Ocampo, G. San Blas, & F. Campon, 1 male (IADIZA); Reserva de Biósfera Teuquito, Ruta Provincial 37, 1 km S “Canal”, 24º21’20,95’’S 61º18’55,23’’W, 11.XII.2008, 1 male and 1 female (IADIZA); Chaco: Fuerte Esperanza, XI.1978, A. Martínez & Fritz, 2 males and 2 females (CMNC); Santiago del Estero: without locality, II.1960, without collector, 1 male and 1 female (IADIZA).
Diagnosis. Length 10.8–11.9 mm; width: 4.8–5.9 mm. Body elongate, brown to dark brown, shiny; coarsely punctate (Fig. 22A); clypeal emargination deep but not reaching the base of the teeth, rounded and narrowed; clypeal lateral margin strongly convex and produced, forming a tooth-like projection; pronotal posterior corners subangulate to rounded (Fig. 22B); antennae with 10 antennomeres; first two pair of elytral ridges equally defined and more noticeable than the other two; basal apophysis of metacoxa produced; metafemur with bristles, sometimes abundantly; metatibia not carinate along the inner margin; pygidium convex, wider than it is long; pygidial width wider than the distance between spiracles of propygidium, disc with bristles throughout, erect bristles (Fig. 22D); in males protarsomeres and mesotarsomeres strongly enlarged, metatarsomeres slightly enlarged; parameres strongly expanded at the midline and abruptly narrowed at the apex (Fig. 22E, F); parameres strongly convex in lateral view (Fig. 22G).
Geographical distribution. ARGENTINA (Formosa, Chaco, Santiago del Estero).
Remarks. Liogenys vicina resembles the sympatric L. latitarsis (Fig. 10), and these similarities difficult their identification. Liogenys vicina differs from L. latitarsis (in parenthesis) in the punctures on pronotum and elytra coarser; clypeal emargination slightly narrower, lateral margins of pronotum slightly rounder, elytral inner ridges evenly elevated (sometimes the second ridge less elevated), metafemur more with bristles; and in the shape of parameres inflated basally and abruptly narrowed at the apex (not inflated basally and apical constriction absent).
