Centistes truncatus

description: Centistes truncatus Román & Sarmiento sp. nov.
(Figs. 22A–G, 24A)
Diagnosis: This species differs from the others by the truncated propodeum and the ventral part of tarsi I to IV of anterior and middle legs with brush-like pubescence. Also, by the combination of characters: propodeum completely costal, without areola, and metapleura with an anterobasal projection.
Comments: Centistes truncatus is differentiated from other species of the genus by its truncated propodeum, although it shares the partial medial development of the notaulus with C. epicaeri, from which it differs widely in other characters.
Description. Female. Body length: mesosoma length 1.67 (1.67–1.77) mm. Head (Fig. 22B–C): antenna with 28 flagellomeres; face setose and smooth, minimum face width 1.2 × clypeus width; face length 0.7 × maximum face width; clypeus setose and smooth, clypeus length 0.3 × its width; gena setose and smooth; frons glabrous medially and smooth; vertex setose and smooth; mandibles when closed overlapping for 0.3 × mandibles length, mandible width basally 0.5 (0.4–0.5) × mandibles length; malar space length 0.3 × eye height in lateral view, and 1.3 (1.1–1.3) × mandible width basally; eye height in lateral view 1.6 × eye length in dorsal view; lateral ocellus separated from compound eye 2.2 (2.1–2.2) × ocellus diameter; temple length 1.2 (1.2–1.9) × eye length in dorsal view. Mesosoma (Figs. 22D, G): pronotum sparsely setose, without transverse dorsal sulcus; pronotum in lateral view smooth, without carinae; median and lateral mesonotal lobes setose anteriorly, smooth; pit on the mesoscutum absent; notauli only medially impressed; mesoscutum width 1.1 (1.0–1.1) × its length; scutellar sulcus with transverse carina; scutellum glabrous, smooth; posterior scutellar depression scrobiculate; mesopleuron setose with a glabrous area medially, smooth; precoxal sulcus present, scrobiculate; metapleuron setose, metapleuron upper and lower part costate, supramesocoxal projection present; propodeum setose, truncated, costate, areolae absent, dorsal longitudinal carinae absent, transverse dorsal carina incomplete. Legs (Fig. 22A): tarsus I to IV of fore legs with brush-like pubescence; claws basal lobe absent.

Paratype: One female, COLOMBIA, Norte de Santander, Cucutilla, Vereda Carrizal sector Sisavita, Quebrada Grande, N 7°26’20” W 72°50’27”, 2380-2520 m, Bosque Andino, Intervención de vuelo, 31-iii-2002, E. González & A. Pulido leg. (Deposited in IaVH. Code: IAvH-E-185304).
Etymology: The Latin word truncatus, meaning truncated or short, refers to the abbreviated form of the basal part of the propodeum.
