Type material. Holotype ♂ (MECN-EN 42057): “ ECUADOR: Napo, -0.65822˚, -77.59197˚, Archidona, Pacto Sumaco, 26.X.2025, 1568m, A. Pazmiño, Winkler ” / “Caterino DNA voucher, Ext. MSC-13352, Morphosp. PS.B.017”; deposited in MECN. Paratypes: 3♀, same data as type (MECN-EN 42003–42005).

Diagnosis. (TL: 1.4mm) Body (Fig. 40D) small, elongate, parallel-sided, finely but distinctly punctate, densely covered with subrecumbent setae; head subtriangular, about 1.25× as long as wide, posterior corners narrowly rounded, base distinctly emarginate; vertexal foveae fine but distinctly impressed, vertexal sulci converging evenly to small, setose median fovea; eyes large, diameter about 1.5× postocular genal length; antennae short, scape thick, cylindrical, antennomere II elongate oval, III–VI beadlike, VII wider, VIII–XI forming loose club, VIII–X transverse, XI about 4× as long as X, apically acuminate; pronotum lacking subbasal tooth, widest just behind middle, sides rounded to neck; posterior constriction strong, sides straight within; lateral pronotal foveae deep, connected by weakly angulate transverse subbasal sulcus; elytra parallel-sided, each with sutural and two smaller lateral foveae, basal carina weakly arched over them, humeri not dentate; venter and legs lacking secondary sexual characters. Aedeagus (Fig. 41C, D) simple, basal bulb small, with distinct basal knob below subbasal constriction; basal bulb evenly narrowed to distal tegmen, which is dorsally slightly split, sinuate just beyond middle, and apically acute.

Etymology. The name of this species refers to its somewhat ‘arrow-like’ head shape. It is used as a noun in apposition.

Distribution. This species is known from the eastern side of the Andes, in lower cloud forest at around 1500m on the southern slopes of Volcán Sumaco.

Remarks. This species has a fairly distinctive head shape, quite triangular, with narrowly rounded basal corners. It can be separated from most others by this, in combination with its very simple aedeagus. A similar aedeagus is seen in J. diazi (compare Figs 41D and 45J), but external differences between these are numerous (pronotal teeth, deep median frontal fovea in J. diazi) enough to suggest parallel simplification of the aedeagus.
