Diagnosis. Female ( Figs. 1-3 ). Integument black and shiny, except posterior and lateral margins of pronotum, meso- and metaventrite, anterior third of elytra, scutellum, and ventrites 1-2 and anterior 3/4 of ventrite 3 red orange. Head. Frons and genae elongate, frons with glabrous quadrangular impression; area between antennal tubercles with feeble median sulcus, surface densely and shallowly punctate, except quadrangular impression; vertex densely punctate and with sparse short and long erect setae; clypeus sparsely punctate with distal margin truncate; mandibles elongate, arcuate at apices; maxillary palpi tri-segmented, with terminal palpomeres broad and apex truncate; eyes large; antennae reaching apical third of elytra; antennomeres sparsely and finely punctate with sparse short black setae; scape wide, slightly longer than antennomere 3, pedicel shorter than antennomere 3, antennomere 3 longer than antennomere 4, antennomere 5 slightly longer than antennomere 4, antennomeres 6-7 equal in length, antennomere 11 longer than antennomere 10 with apex pointed; antennomeres 5-11 thickened. Thorax. Slightly longer than wide, anteriorly narrower than posteriorly; sides sinuate, impressed behind middle; posterior margin with a small depression at each side of middle; sides sparsely and finely punctate; disk convex, inflated, glabrous. Prosternum finely, irregularly punctate; mesoventrite densely punctate, with short, golden setae; metasternum finely, sparsely punctate, clothed with short, golden hairs. Elytra. Longer than wide; wide at base tapering slightly to apex; humeri developed, somewhat slightly pointed; surface sparsely punctate anteriorly, denser, and finer to apex; each puncture bearing a short, suberect seta; apices broad, obliquely emarginate-truncate, outer angles pointed and inner angles with a minute tooth. Legs. Slender; sparsely punctate; dorsal surface of femora and tibiae clothed with short, erect black setae, ventral surface with short, suberect golden setae; ventral surface of tarsi with short golden setae; femora widened to distal area; hind femora carinate at basal half. Abdomen. Very sparsely, shallowly punctate; glabrous, except ventrite 5 with short black pubescence at posterior margin. Ventrite 5 longer than ventrite 4; sparsely and finely punctate; apex rounded.

Dimensions. Total length, 15.00 mm; head length, 3.80 mm; prothoracic length, 2.10 mm; humeral width, 3.10 mm; elytral length, 9.10 mm.

Distribution. Currently, Cyphonotida rostrata rostrata is known from North America (United State and Mexico), Central America ( Guatemala, El Salvador, and Nicaragua) and South America ( Colombia, Guiana, Ecuador, Brazil, and Bolivia) ( Linsley & Chemsak 1976; Giesbert & Hovore 1998; Monné & Monné 2008; Monné 2023). One female specimen from Peru is listed below, representing a new country record for this subspecies.

Material examined. Female from PERU, Lambayeque region, Chiclayo province, Pimentel district , San Agustín village , 06°48’12’’S, 79°53’42’’O, 15 m, 07.II.2023, manual collection, Daniela García leg. ( MUPRG) (New country record) .

Ecology. The female specimen was collected in an anthropogenic disturbed area of seasonally dry forest on flowers of Baccharis salicifolia (Ruiz & Pav.) Pers. ( Asteraceae ) ( Fig. 7 ). Adults of Cyphonotida rostrata rostrata have been taken on flowers of the genera Guardiola Cerv. Ex Bonpl. , Baccharis L., Brickellia Raf. ( Asteraceae ) and Petalostemon Michx. ( Fabaceae ) ( Giesbert & Hovore 1998) and Croton L. ( Euphorbiaceae ) ( Bezark 2023).

Remarks. Cyphonotida rostrata rostrata is highly variable in color; the pronotum, legs and elytra vary between black and red-orange. Indeed, the holotype described by Bates (1872) has head, elytra and legs black, while the prothorax is red-orange. Some specimens collected in other countries ( Guatemala, Costa Rica, and Bolivia) have the pronotum completely black or red-orange, or black with posterior margin red-orange, or with anterior half black and posterior half red-orange; the elytra are completely black, or black with anterior third red-orange, or completely red-orange with outer margins black; the legs are black, or femora red-orange and tibiae and tarsi black, or femora with basal half red-orange and apical half black ( Figs. 4-6 ). However, the color pattern black in head and antennae appears to be more consistent in this species.

Cyphonotida rostrata rostrata is very similar to subspecies C. rostrata borealis , C. rostrata ventralis and C. rostrata texana by the body form and the color pattern of the body. However, in C. rostrata borealis the frons is shorter, the humeri are somewhat rounded and the elytral apices are obliquely truncate with the outer angles less produced, the color of the prothorax is entirely reddish, and the elytra piceous with at least a reddish spot on the humeri. In C. rostrata texana the antennae are stouter with segments strongly thickened and the humeri somewhat more acute; being the color pattern red-orange in the prothorax and black in the elytra. In C. rostrata ventralis the elytral apices are obliquely truncate with the outer angles feebly produced ( Linsley & Chemsak 1976; Giesbert & Hovore 1998).
