( Figures 7–9 View Figure 7 View Figure 8 View Figure 9 )
Type material
Holotype: female, [ CHILE: Talca ;/ Vilches , 14–15/Dec. 1976, Gurney /and Barria] [ USNM/2008983 About USNM ] ( USMN) . Paratype: one male, data as holotype .
Etymology
The name refers to Juan José Morrone, our professor and friend, who has contributed enormously to the knowledge of the Andean weevil fauna.
Diagnosis
This species is recognized by the combination of the following characters: ovate to subcircular, flat mandibular scar, placed at apex of a cylindrical and well-developed pedicel; rostrum with slightly developed central carina; scape reaching posterior margin of eyes when resting in scrobe; intervals 5–7 convex at bases, resulting in protuberant humeri; interval 3 with rounded, low, declivital tubercle; slightly elongate on anterior–posterior axis, and covered mostly by white subcircular scales and numerous apical, translucid, and costate seta-like scales (ornamentation visible up to ×60); ventrite 5 with central area smooth (integument exposed); both lateral areas of ventrite 5 covered by white, subcircular scales; tibia 3 with enclosed corbel, lenticular area covered by abundant setae.
Description
General habitus as in Figure 7 View Figure 7 . Body length 8.85 mm in female and 6.95 mm in male. General body shape ovate. Integument mostly covered by scales; black in exposed areas (e.g. rostrum apex). Vestiture mainly of subcircular scales, ornamented with longitudinal ribs visible up to ×100. Vestiture colour mixed; dorsal surface of body mainly of an irregular mix of white and iridescent pink scales. However, prothorax exhibiting more uniform distribution of colours as follows: two white longitudinal stripes at each side of prothorax median sulcus; each of these followed by a longitudinal pink iridescent stripe; each followed by a new white stripe. Basal area of interval 3 completely covered by white subcircular scales and decumbent, costate seta-like scales (ornamentation visible up to ×60), this vestiture covering interval 3 from base to 4th punctuation and visible as a lighter stripe on elytra. Seta-like scales abundant on declivital tubercle on interval 3 and sparse on dorsal surface of rostrum and prothorax, most elytra intervals, femora, and ventrites. White scales covering venter area both in male and female. Mandibular scar present, strongly developed, subcircular to ovate in shape, lacking conical protuberance; placed at apex of a well-developed cylindrical pedicel; pedicel showing several long setae and white seta-like scales on its external side. Rostrum two times longer than wide, poorly developed central carina. Suprascrobal sulcus present. Frons slightly convex, elongated fovea (less evident in female). Scrobes incurved, directed downward to lower margin of eyes; as in all species of genus, distal half of scrobe presenting several subcircular scales. Eyes ovate and flat, longer axis dorso-ventrally orientated. Antennal scape reaching posterior margin of eye when resting in scrobe. Funicular articles conical; article 2 longer than 1 (approximately two times longer); articles 3–7 sub-equal in size and slightly shorter than article 1. Club ovate, short, inflated. Prothorax subquadrangular, 1.2 times longer than its maximum width in female and male; lacking anterior impression, with strongly developed median sulcus on dorsal surface, irregular impressions ornating both sides of sulcus. Postocular lobes present. Prothorax base with a brush of multifid setae. Scutellum visible and round. Elytra 1.5 times longer than maximum width in female and 1.6 times in male. A brush of multifid setae densely covering the anterior margin of elytra. Intervals 5–7 notably protruding at basis, resulting in protruding humeri. Intervals 3 and 5 strongly convex, especially at apical third. Intervals 7 and 9 just slightly convex. Short and rounded declivital tubercle on interval 3; this tubercle slightly elongated following the anterior–posterior axis and mostly covered by white subcircular scales with numerous translucid, costate seta-like scales at apex. Similar vestiture on interval 3 base and on declivital area of interval 5. Intervals 3 and 9 fused at end, resulting in an inconspicuous rib continuing toward the elytral apex. Elytral apex slightly acuminate and with abundant setae. Venter area completely covered by subcircular scales, excepting middle area of ventrite 5 lacking scales. Venter joints between ventrites 2 and 3, 3 and 4, and 4 and 5 notably deep. Ventrites 3+4, 3.5 times shorter than ventrites 1+ 2 in female and 3.2 times shorter in male. Apex of tibiae 1 and 2 with comb of enlarged setae, continuing around tibial apex, but briefly interrupted in dorsal edge of apices. Tibia 3 with enclosed corbel, surrounded by setae, defining an internal and external comb (following nomenclature by Thompson 1992). Lenticular area limited by combs, flat and setose. All tibiae slightly mucronate in female and strongly mucronate in male. Female genitalia as in Figure 8 View Figure 8 . Male genitalia as in Figure 9 View Figure 9 .
