Description.

Body elongate oval, moderately convex. Mandibles, head, pronotum, hypomera, prosternum, scutellum and elytra black, with slight bronze lustre on head and pronotum; labrum, antennae and legs dark testaceous, with 3–4 basal antennomeres and tarsi paler; palpi ochre. Length: 6.7 mm; width: 3.4 mm (range of male specimens: 5.6–7.8 mm long, 2.8–3.9 mm wide).

Frons alutaceous, unpunctured, finely microsculptured, with supraocular sulci reaching beyond middle of dorsal edge of supraantennal calli; clypeus similarly microsculptured with few tiny punctures on disc, and anterior border with nearly semicircular small emargination. Eyes large, separate on frons by 2.1 × their transverse diameter. Antennomeres 3–9 weakly impressed longitudinally and slightly compressed along ventral part; relative proportions of antennomeres: 2.2-1.0 - 1.6 - 1.8 - 2.1 - 2.0 - 2.3 - 2.2 - 2.2 - 2.1 - 2.6. Surface of pronotum finely alutaceous, with very dense tiny shallow micropunctures and sparse large punctures on disc and lateral declivities, glossier than frons. Prosternal process half as wide as transverse diameter of procoxae. Elytra about 1.3 × as long as ensemble width at base, widest behind humeri, gradually tapering to slightly acuminate apex in apical half; surface finely alutaceous, smoother and shinier than pronotum, with relatively large punctures, smaller than intervals, rather confused on disc; last interval relatively flat. Basitarsomeres enlarged, wider than third tarsomere and nearly as long as second and third tarsomeres combined in protarsi, and as wide as third tarsomere and slightly shorter than second and third combined in meso- and metatarsi. Median apodeme of first abdominal ventrite about half as long as ventrite, arched, narrower than mesosternal process; all ventrites finely alutaceous, with sparse fine punctures and long fine, posteriorly adpressed pale yellow setae. Penis (Fig. 9 d View Figure 9 ) thin and slender, regularly curved ventrally, with sides slightly concave in ventral view, slightly widened preapically; apex elongate, arched and slightly sinuous distally towards long blunt tip; gonopore short oval, with distal end separated from apex of penis by distance much longer than maximum width of gonopore; dorsal flap subrectangular, shorter than wide, covering less than basal half of gonopore. — Females. In this species, elytra are also proportionally longer in females, the pronotum is not enlarged laterally and the marginal gutter is narrower (inset in Fig. 10 a View Figure 10 ). Spermatheca (Fig. 1 t View Figure 1 ) shaped like question mark, with cornu shorter and more bulbous than nodulus; nodulus sigmoidal slightly thicker basally, with short protruding insertion of spermathecal gland submedially, opposite to cornu; spermathecal duct uniformly thin, longer than nodulus, inserted laterally near base of nodulus, oriented opposite to cornu, bent in wide curve towards cornu, often crossing body of spermatheca to curve in opposite direction, without coils.

Diagnosis.

This species is among the largest of the genus, most typically surpassing 6.0 mm in length, and it is rather characteristic, with males showing traits that are not shared with any other species in the group. They have elytra widest at level of humeri and a rather acuminate profile towards apex, together with a particularly enlarged pronotum, as wide or wider than elytra, with relatively wide gutter-like margin; females have subparallel elytra like several other species in the group and their pronotum is not particularly wide, but their size, only comparable to the species in the C. thyiana group, together with narrow prosternal process (always wider than coxae in females of the C. thyiana group) and lustrous dorsal appearance help recognizing them. This is the only known species of Cazeresia without coils in the spermathecal duct.

Derivatio nominis.

The species name is a Latin adjective (f.) resulting from combining the adjective latus, meaning wide, with the noun collum, meaning neck, thus describing the characteristic large pronotum of the males of the species.

Distribution.

The species has a relatively large range in moderate elevations (220–630 m a. s. l.) of the mountain ranges of the central part of Grande Terre (Fig. 8 c View Figure 8 ).
