Type material.

Holotype male (IAZA), pinned. Original labels: a) "RA Mza Santa Rosa / Ñacuñán tramp luz UV / 12-X-02 G. Flores"; b) red paper "Parochodaeus / proceripes / ♂ / Paulsen & Ocampo / HOLOTYPE".

Type locality.

Argentina: Mendoza: Santa Rosa.

Diagnosis.

Parochodaeus proceripes (Fig. 14) is similar to Parochodaeus phoxus in that it also has a large frontoclypeal horn, but the horn of this species is larger, more anterior, and is almost entirely located on the clypeus. The slender metatibiae are unique among horned species in Argentina.

Description, holotype male.

Length:8.1 mm. Width:4.2mm. Head: Surface shiny, weakly tuberculate, punctate; punctures small, sparse. Vertex with frontoclypeal horn (Fig. 2). Clypeus subtrapezoidal, long (length equal to 1/2 width); anterior margin not thickened, broadly rounded. Labrum broadly emarginate. Mandibles strongly angulate externally. Mentum with distinct longitudinal furrow for entire length. Pronotum: Form strongly convex, declivous anteriorly. Surface densely tiled with tubercles; tubercles moderate in size, setose; surface between tubercles punctate; punctures fine. Elytra: Setae of interstrial tubercles short, erect. Legs: Protibia with apical spur curved externally; internal apical tooth absent. Metatrochanter simple. Metafemur with posterior margin simple. Metatibia straight, slender (width approximately 1/5 length; Fig. 6), gradually expanding to apex. Metatarsomere 1 not greatly enlarged. Abdomen:Stridulatory peg present.

Etymology.

The specific epithet ‘proceripes’ is derived from the Latin procerus "long, slender" and pes "foot, leg", referring to the slender metatibiae, which are unusual in species with a frontoclypeal horn. The name is used a masculine adjective in the nominative singular.
