Taxonomic review of Cratocerus Dejean, 1829 (Coleoptera, Carabidae) with the description of six new species.

Grzymala TL, Will KW - Zookeys (2014)

Bottom Line: A diagnosis of the South and Central American genus Cratocerus Dejean (Coleoptera: Carabidae) and a key to all species is provided.Eight species are recognized including six species that are newly described: Cratocerus sinesetosus sp. n. from French Guiana and Peru; Cratocerus multisetosus sp. n. from Costa Rica and Panama; Cratocerus tanyae sp. n. from Costa Rica, Guatemala, and Mexico; Cratocerus indupalmensis sp. n. a species widely distributed throughout Central and South America; Cratocerus kavanaughi sp. n. from French Guiana and Peru; and Cratocerus culpepperi sp. n. from Peru.A lectotype for Cratocerus sulcatus Chaudoir is designated.

ABSTRACT
A diagnosis of the South and Central American genus Cratocerus Dejean (Coleoptera: Carabidae) and a key to all species is provided. Eight species are recognized including six species that are newly described: Cratocerus sinesetosus sp. n. from French Guiana and Peru; Cratocerus multisetosus sp. n. from Costa Rica and Panama; Cratocerus tanyae sp. n. from Costa Rica, Guatemala, and Mexico; Cratocerus indupalmensis sp. n. a species widely distributed throughout Central and South America; Cratocerus kavanaughi sp. n. from French Guiana and Peru; and Cratocerus culpepperi sp. n. from Peru. A lectotype for Cratocerus sulcatus Chaudoir is designated. Habitus images are provided along with illustrations and images of male genitalia, female genitalia, and diagnostic morphological characters.

Mentions: Microsculpture. Head dull in appearance with isodiametric microsculpture; pronotum shining with markedly transverse microsculpture; procoxa distinctly granulate isodiametric; abdominal sternites with transverse microsculpture. Head. Prominent supraorbital ridge, occasionally with slight rugosity; one or two pairs of supraorbital setae. Frons glabrous. Fronto-clypeal suture distinct. Clypeus with pair of setae present mediolaterally. Labrum with six anterior marginal setae, outer pair length 1/3 × middle pair, middle pair length 1/3 × inner pair; apex of labrum often slightly medially emarginate. Mentum with one pair of setae and prominent medial tooth, submentum with two pairs of setae; transverse suture between mentum and submentum complete. Scape glabrous except for one dorsal seta; pedicel length 1/3 × length of scape, constricted at base with slight apical expansion, with one ring of testaceous setae surrounding apex, antennomere 3 length 1 ½ × that of scape, longer than wide, with several rings of testaceous setae confined to apical 2/3; antennomeres 4–10 transverse and subequal to one another, covered with dense pubescence similarly colored to integument laterally, resulting in matte appearance, midline of antennomeres moderately pubescent; antennomere 11 slightly longer than 10 and broadly rounded apically; antennal length extended to pronotal base. Thorax. Pronotal disc 1.1–1.4 × wider than long. Median impression distinct, single basal fovea laterad or pair of fovea laterad with additional fovea overlaying medial impression. Pronotal hind angles sharply denticulate. Elytral length 2.3–2.9 × pronotal length and 1.3–1.6 × elytral width; striae moderately impressed, impunctate or crenulostriate, striae 1, 2, and 7 reaching elytral apex; striae 3 and 4 anastomozing anterad of elytral apex; striae 5 and 6 anastomozing anterad of elytral apex; intervals slightly convex or subtectiform; elytral humeri sharply denticulate; apex rounded, not truncate; plica absent. Legs. Protarsomeres 1–4 of males with paired rows of ventral setal pads formed from squamate setae; females with ventral mediolateral spines. Metatrochanter with one basal seta. Metafemur anterior face with one seta basally located and one medially located. Abdomen. Abdominal sternites IV–VII glabrous except for a single pair of ambulatory setae; males without setiferous fovea; males and females with single pair of setae on sternite VII. Males with parameres glabrous, left paramere larger than right paramere, left paramere with simple to complex curvature (Fig. 11a–g). Females without medial sclerotized ramus at base of gonocoxa; gonocoxa IX clearly separated into basal and apical aspects, gonocoxite 1 and gonocoxite 2; gonocoxite 2 apex pointed and curved laterad, with short, single, broad lateral ensiform seta and short, single, broad dorsal ensiform seta, apical sensory furrow with two nematiform setae; spermathecal gland lacking.
