Type material

(3). Holotype labeled "Colombia, La Guajira, Uribia, PNN La/Macuira Corregimiento Nazareth/ Kajashiwoü, 12°11'37.9"N; 71°21'30.1"/W. WGS84, 70 m. Manual.19.ix.2014/C. Medina" [IAvH-E-195379]. Allotype [IAvH-E-195380] and one female paratype [IAvH-E-195381] with the same label data. Types deposited at the Instituto Alexander von Humboldt (IAvH) Villa de Leyva, Boyacá, Colombia.

Diagnosis.

Coelosis wayuorum sp. n. can be separated from the other Colombian Coelosis by the following characters: maxilla with lateral sclerite pronounced (Fig. 5C) [similar to C. bicornis , but not as in C. biloba ]; galea without teeth (Fig. 5C) [two teeth in both C. bicornis and C. biloba ]; ventral surface of the mandibles with keels 1 and 2 contiguous (Fig. 4H) [widely separate in C. bicornis (Fig. 4B), slightly separate in C. biloba (Figs 4E)]; pronotum and elytra strongly punctate, punctures with short, spine-like setae (Figs 6C, E) [spine-like setae absent in both C. bicornis and C. biloba (Fig. 6A, B, D)]; prohypomeron with spine-like setae [slender and long in C. bicornis , slender and short in C. biloba ]; mesosternum convex as in C. biloba [concave in C. bicornis ]; metasternum covered with short, spine-like setae (Fig. 6G) [setae long and slender in both C. bicornis and C. biloba (Fig. 6F)]; and meso- and metatibiae densely punctate (Fig. 6J, K) [scarcely punctate in both C. bicornis and C. biloba (Fig. 6H, I)]. The internal sac is different among the species: in C. biloba , the accessorial lamella is short and simple (Fig. 5H), while in C. bicornis and C. wayuorum sp. n. the lamella is long and complex, although with differences between these two species (Fig. 5G, I).

Description.

Holotype male (Fig. 3F). Body length 20.2 mm; width 11.00 mm. Color dark reddish brown. Head: Frontoclypeal region with small horn, surface rugopunctate, punctures setose, setae spine-like (Fig. 3F). Clypeus strongly rugopunctate, slightly emarginate, apex broad with two reflexed teeth. Mandibles with three conical teeth, subapical notch slightly deep (Fig. 4G, H); labium rugopunctate, with sparse, short, spine-like setae, paraglossa undeveloped, narrow, apex truncate (Fig. 4I); maxilla with lateral projection, galea without teeth (Fig. 5C). Pronotum: Surface sparsely punctate; punctures moderately large, umbilicate, setose; setae spine-like (Fig. 6C). Disc with two small, widely separated horns, wide fovea between horns (Figs 3F, 6C). Elytra: Surface with 10 distinct pairs of striae composed of ocellate punctures bearing short, spine-like setae, micropunctures densely intermixed between striae (Fig. 6E). Pygidium: Surface sparsely punctate, punctures small to moderate in size, weakly ocellate, with short spine-like setae, becoming denser at basal angles. Surface regularly convex in lateral view. Legs: Protibia tridentate, basal tooth reduced. Meso- and metatibiae with one medial transverse carina, each with short, spine-like setae and one small inner tooth (Fig. 6J, K). First metatarsomere apically expanded, apex subtruncate with acute outer projection (Fig. 6M). Venter: Prosternal process subtriangular, thick; apex short, parabolic, with process at middle, this process with short, stout setae (Fig. 5F). Mesosternum densely punctate, setose, slightly convex at middle. Metasternum densely punctate; punctures ocellate, minutely setose; setae spine‒like; lateral edge rugopunctate with short, spine-like setae. Abdominal ventrite VIII depressed at middle. Genitalia: Parameres as in Fig. 7E, F, internal sac as in Fig. 5I.

Allotype

(Fig. 3G). Female. Similar to holotype except for the following: body length 22.4 mm; width 12.0 mm, frons and disc of pronotum smooth, without fovea or horns, pygidium slightly concave in lateral view, and genital plate as Fig. 5L.

Paratype (1). Similar to allotype except for the following: body length 25.5 mm; width 13.0 mm.

Etymology.

The specific epithet wayuorum refers to the Wayuu indigenous group inhabiting the Guajira Peninsula.

Distribution.

Coelosis wayuorum sp. n. is known only from one locality in Macuira National Park, Colombia (Fig. 8).

Temporal distribution.

Three specimens collected in September 2014, during the dry season.

Life history.

The type material was collected at night with lights during the dry season.
