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 (

). Scutellum black (
Fig. 1, 5
). Elytra black with raised humeral callosity, lateral margin slightly reflexed, light brown (

). 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

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 (

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.
