Type material.
Holotype ♂, with labels: [white printed label] “ ECU. Napo, 10200 ’ / Papallacta / 21. V. 82, H. Frania / canopy dead tree ”, [red label] “ Holotype Yuracarus / napoensis Chani-Posse et al. 2025 ” ( CNC) . Seven paratypes: 2 ♂, 4 ♀ (Fig. 2 E View Figure 2 ) with same data as above , one ♂ with white printed label “ ECU. Napo, Baeza / 7800 ’ 6.VI.1982 / H. Frania, ridge / top leaf litter ” ( CNC) . All paratypes with additional red label: “ Paratype Yuracarus / napoensis Chani-Posse / et al. 2025 ”.
Diagnosis.
Yuracarus napoensis 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, the distance separating the medial interocular punctures on the frons 3 × distance separating the medial punctures from the lateral punctures, and the head narrower than pronotum (HW / PW = 0.9).
Description.
Body length 9.6–10.7 mm (5.1–5.7 mm, abdomen excluded), body overall scarcely setose, almost glabrous. — Colouration: Head and thorax metallic greenish blue, elytra mostly metallic purple to greenish purple apically, abdomen shiny black to piceous-black; antennae, palpi and legs piceous to piceous-black. — Head: about as long as wide (HW / HL = 1.0), slightly narrower than pronotum at widest point (HW / PW = 0.9); epicranium with medial interocular punctures separated by distance 3 × as large as distance separating medial punctures from lateral punctures. Eyes distinctly shorter than temples (EL / TL = 0.6) 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) 1.8 × 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 shorter than fifth (S 1 / S 5 = 0.8). — Elytra: at sides moderately longer than pronotum at midline (EtL / PL = 1.2). — Male sexual characters: Sternum 8 moderately emarginate medio-apically (Fig. 5 K View Figure 5 ). Aedeagus with median lobe gradually narrowed from base into a subacute apex, internal sac with one pair of elongate and sclerotized structures (Fig. 6 G View Figure 6 ). — Female sexual characters: As described for the genus, with tergum 10 arcuate apically, accessory sclerite horseshoe-shaped.
Geographical distribution.
Yuracarus napoensis sp. nov. is currently recorded only from the locality of Napo in the Andes of Ecuador, at approximately 2370 and 3100 m of altitude (Fig. 7 View Figure 7 ).
Etymology.
The specific name napoensis is a Latinized adjective referring to the locality of Napo, where this species was collected.
