Figs 5I–J , 25

Diagnosis

A medium-sized species (10 mm) distinguishable among other congeners by the combination of the following features. Head frontal fovea short and deep ( Fig. 5J ). Pronotum short, with three pairs of marginal setae; median line shallow; posterior impressions deep. Elytra elongate, ovate, with punctate striae ( Fig. 5I ). Adults of P. zaguryi sp. nov. and P. rotundipenne are quite similar, as both have a short pronotum with three pairs of marginal setae, but in the former the tarsomeres 5 bear a row of a few slender setae on each ventral margin, while in the latter the tarsomeres 5 are glabrous ventrally.

Etymology

The specific epithet ‘ zaguryi ’ is an eponym in honor of the Brazilian coleopterist Fernando Zagury Vaz de Mello, who lent us Carabidae beetles important for the present work and other taxonomic and morphological studies in progress.

Description

Male (holotype, fully pigmented adult)

MEASUREMENTS (in mm). AL1 0.8, AL2 0.3, EL 5.0, EW 3.8, PL 3.0, PW 3.1, HL 1.5, HW 2.2, TL 9.5, TL/EW 2.5, lp2L 0.6, lp3L 0.6, lp3 W 0.4, mp3L 0.3, mp4L 0.4, mp4 W 0.4.

BODY. Elongate, flat; head, pronotum and elytra dark reddish brown; glabrous ( Fig. 5I ). Ventral surface dark reddish brown.

HEAD. Microreticulate; frontal foveae deeply impressed, short, not extended ( Fig. 5J ). Antennae reddish brown, long, reaching anterior portion of elytra; antennomeres 1–3 with few long, sparse yellowish setae at apical portion; antennomeres 4–11 fully covered with short yellowish setae. Apical labial and maxillary palpomeres with long, sparse yellowish setae; triangular, reddish brown, with apicalmost portion lighter.

PRONOTUM. Slightly wider than long; sides arcuate, each with three long setae; median line long, shallowly impressed, with anterior edge limited by elongated punctation; posterior impressions deep toward the pronotal disc.

ELYTRA. Elongate, ovate, each with 7 deeply impressed striae, markedly punctate; in between striae shiny and impunctate.

LEGS. Dark reddish brown; protarsomeres 1–4 expanded, ventrally with vestiture of adhesive setae; protibiae expanded at apex, with few long yellowish setae ventrally and surrounding antennal cleaner; mesotibiae slender, with few long yellowish setae throughout inner margin, slightly expanded at apex; metatibiae slender, with few long yellowish setae ventrally on apical half.

Female

Unknown.

Remarks

We include P. zaguryi sp. nov. in the P. punctatostriatum species group due to the punctiform frontal impressions of the head, deep posterior impression of the pronotum and tarsomeres 5 having rows of setae on the ventrolateral margin.
