Mazurek ” ( FMNH) . All paratypes with additional red label: “ Paratype Yuracarus / yunguensis Chani-Posse / et al. 2025 ”.
Diagnosis.
Yuracarus yunguensis can be identified among other species of Yuracarus by the following combination of characters: antennomeres 8–10 quadrate, eyes at least 0.6 × the length of the temples, and the distance separating the medial interocular punctures on the frons not more than 2.0 × distance separating the medial punctures from the lateral punctures.
Description.
Body length 9.2–10.7 mm (5.2–5.6 mm, abdomen excluded), body overall scarcely setose, almost glabrous. — Colouration: Head and thorax metallic greenish blue, elytra mostly metallic purple basally to greenish blue apically, abdomen shiny black to piceous-black; antennae, palpi and legs piceous to piceous-black. — Head: slightly longer than (HW / HL = 0.9), as long as pronotum at widest point (HW / PW = 1.0); epicranium with medial interocular punctures separated by distance 2.0 × as large as distance separating medial punctures from lateral punctures. Eyes moderately shorter than temples (EL / TL = 0.8) seen from above. Antennae with first antennomere distinctly shorter than second and third combined, third 1.1 × slightly longer than second, fourth-seventh longer than wide, eighth-tenth about as long as wide. Labial palpus with third palpomere 1.5 × as long as second. Maxillary palpus with fourth palpomere (apical) 1.2 × as long as third. Neck about 0.4 × as wide as head at widest point. — Pronotum: moderately longer than wide (PW / PL = 0.8), dorsal rows of punctures each with 4 punctures. — Legs: Mesotarsi shorter than mesotibiae, metatarsi shorter than metatibiae, first metatarsomere slightly shorter than fifth (S 1 / S 5 = 0.9). — Elytra: at sides distinctly longer than pronotum at midline (EtL / PL = 1.3). — Male sexual characters: Sternum 8 deeply emarginate medio-apically. Aedeagus with median lobe gradually narrowed from base into rather acute apex, internal sac with one pair of elongate and sclerotized structures (Fig. 6 E View Figure 6 ). — Female sexual characters: As described for the genus, with tergum 10 truncate apically (Fig. 5 P View Figure 5 ).
Geographical distribution.
Yuracarus yunguensis sp. nov. is currently recorded from the Andes of Peru and Bolivia, at 2800 m and 4100 m of altitude (Fig. 7 View Figure 7 ).
Etymology.
The specific name yunguensis is a Latinized adjective referring to the Yungas ecoregion, where this species was collected.
