Diagnosis.

Parochodaeus jujuyus (Fig. 11) is the only Argentine species of the Parochodaeus pectoralis group. Members of this species group have greatly enlarged first metatarsomeres (Fig. 5) and often have the mentum produced ventrally.

Description, holotype male.

Length:7.0 mm. Width:3.5mm. Head: Surface weakly tuberculate, shiny, punctate; punctures moderate, setose. Frons unarmed but with 2 indistinct tumosities. Clypeus broadly rounded, narrow, short (length equal to 1/4 width), margin thickened, produced anteriorly, as long as remainder of clypeus. Labrum emarginate. Mandibles rounded externally. Mentum deeply furrowed, produced downward laterally. Pronotum: Form convex. Surface with weakly tuberculate, setose punctures mixed with glabrous punctures; punctures moderate in size. Elytra: Setae of interstrial tubercles moderately long, erect, somewhat abraded. Legs: Protibia with apical spur weakly curved; internal apical tooth absent. Metatrochanter simple. Metafemur with posterior margin simple. Metatibia slender, (~5 × longer than wide) gradually widening to apex. Metatarsomere 1 subrectangular (not cylindrical), greatly enlarged (longer than greatest width of metatibiae), weakly curved. Abdomen:Stridulatory peg present.

Description, allotype female. Length:6.0 mm. Width:3.0 mm. Differs from male holotype in the following external characters: Head:Clypeus longer (length equal to 1/2 width); anterior margin not produced anteriorly. Elytra:Setae more abraded.

Description, paratypes (n=2). Length:5.8-6.6 mm. Width:3.1-3.3 mm. Not differing significantly from the holotype except with dorsal vestiture less abraded.

Etymology.

The specific epithet ‘jujuyus’ is an unconventional but euphonious Latinized form of the province name Jujuy, gender masculine.

Distribution

(Map 2). 4 specimens examined.

ARGENTINA: JUJUY: Parque Nacional Calilegua El Cortaderal (1); SALTA: Campo Quijano (30 Km E) (2), Parque Nacional El Rey (1).

Temporal distribution.

February (3), December (1).

Remarks.

This species is known from only four specimens and is from the far north of Argentina. The habitat in the region is montane forest. Label data indicates that the paratypes were collected in flight-intercept traps, which is the most common method of collection for forest ochodaeids.
