Figs. 1–15

Diagnosis. Oblong semicircular, black with the lateral and frontal border of pronotum orange brown. Elytra with lateral border and four orange brown maculae pattern, appearing as a four leaf clover.

Holotype. Male. Length: 2.80–3.00 mm. Width: 2.50–2.70 mm. Body rounded, convex, punctuation uniformly distributed on pronotum and elytra ( Fig. 1 ). Head dark brown ( Fig. 5 ), antenna (fig. 8) and mouthparts light or dark brown ( Fig. 2 ). Pronotum black, with antero-lateral margins light brown ( Fig. 1, 3, 5 ). Scutellum black ( Fig. 1, 5 ). Elytra black with raised humeral callosity, lateral margin slightly reflexed, light brown ( Fig. 1, 3, 5 ). Each elytron with two light brown maculae: the first, subtriangular close to suture and base of elytron with an emargination above the humeral callus; the second, slightly smaller than first and subtriangular, near the suture and external margin of elytron ( Fig. 1, 3, 4, 5 ). Epipleura and abdominal sterna light brown, epipleura glabrous and abdominal sternites with small setae and small punctures. The center of pro, meso and metathorax dark brown ( Fig. 2 ). Legs dark brown, robust. Abdomen with six visible sternites in male, the fifth a little larger than the second, third or fourth with posterior margin emarginate, the sixth sternite small ( Fig. 7 ); five sternites in female, fifth is larger than the second, third or fourth, with posterior margin rounded ( Fig. 12 ).

Male genitalia. Median lobe symmetrical, lanceolate, broad at basal third abruptly narrowing at apex, 1/3 shorter than paramere; trabes rather stout, a little longer than median lobe and a little shorter than paramere; paramere constricted at base and wider in apical 1/3, with dense and long pubescence at lateral sides and apex ( Fig. 9 ). In lateral view paramere with apex strongly bent ( Fig. 10 ). Sipho long, uniform diameter throughout most of length, strongly sclerotized, bent, with apex membranous, twisted ( Fig. 11 ).

Female genitalia. Coxites long, about 3.8 times longer than wide, subtriangular, slender, apex rounded; bursa copulatrix large ( Fig. 13 ); infundibulum long, cup-shaped ( Fig. 14 ); styli small with three long setae ( Fig. 15 ). Spermatheca missing.

Type Material. Holotype: PERU. [Chanchamayo, 07/I/1986, Arellano Coll./ UA 2005-86], ( Fig. 6 ), male, deposited at the Museo de Entomología Klaus Raven Büller, Universidad Nacional Agraria La Molina, Lima, Perú ( UNALM). Paratypes: PERU. [Chanchamayo, 07/I/1986, Arellano Coll./ UA 2005-86], 2 female, deposited at the Museo de Entomología Klaus Raven Büller, Universidad Nacional Agraria La Molina, Lima, Perú ( UNALM); same data and locality, 1 female, deposited at the Coleção de Entomológica Pe. J. S. Moure, Universidade Federal do Paraná, Curitiba, Paraná, Brazil ( DZUP).

Remarks. Harpasus quadrifolium González, Corrêa & Almeida sp. nov. has a pattern of maculae which is distinct from the other species. H. aureus Almeida & Carvalho, 2006 is unicolorous, bright golden brown, and yellowish at the lateral margin of the elytra. In Harpasus zonatus ( Mulsant, 1850) the integument is bright golden brown, with a dark brown stripe on sutural and lateral margin of each elytron; in H. eversmanni ( Mulsant, 1850) the integument is reddish at lateral margin with a blue-metallic area at the disc of each elytron; in H. pallidilabris , the type species of the genus, the integument is bluish-green, without any maculae or stripes. The male genitalia of the new species are similar to H. aureus and H. zonatus except that the apex of the sipho is twisted in H. quadrifolium and truncate in H. aureus . In H. zonatus the paramere is wider than in the other species. The female genitalia are similar to H. aureus and H. eversmanni , but differ in the shape of the bursa copulatrix, and in possessing longer and wider coxites.

Etymology. This species is named after the pattern of maculae like a four leaf clover.
