Paratypes
. Same data as holotype (
3 m
#,
INPA
), with yellow paratype label.
Type locality
BRAZIL
.
São Paulo
: Pederneiras.
Diagnosis
Body surface covered with conspicuous pubescence (
Figure 1
(a)). Male antennal scape quite elongate, with a broad, cylindrical internoapical process bearing a dense apical tuft of setae proportionally longer than the other setae on scape (
Figure 2
(a,c)); pedicel globose, internally untoothed (
Figure 2
(a,c)). Secondary sublateral line of pronotum present and completely effaced at posterior half (
Figure 2
(a)). Male genitalia as in
Figure 2
(e).
Description, male
(
Figures 1a–c
;
2a, c, e
).
Length
1.6–1.7 mm
(
1.63 mm
holotype
), width
0.63–0.67 mm
(
0.64 mm
holotype
).
Colouration
. Body predominantly and uniformly reddish testaceous, with head and pronotum slightly darker than elytra.
Head
(
Figure 2
(a)) large, 1.2 times wider than long and medially as long as pronotum, with dorsal and ventral surface conspicuously pubescent, with moderate, decumbent pale setae inserted in deep punctures. Frons wide, slightly depressed anteriorly; punctures smaller than an eye facet, separated from each other by 1.8 puncture diameters; surface smooth between punctures; interocular width 5.4 times transverse eye diameter. Clypeus truncate.
Antennae
slightly longer than half the body. Scape elongate, as long as pronotum, somewhat straight and moderately setose at basal half; apex strongly deflected, with a cylindrical, broadly rounded inner projection bearing a dense apical tuft of moderate setae. Pedicel globose, not projected, similar in size to segments 3–8. Segments 9–11 longer than preceding flagellomers and forming a loose club, each slightly longer than wide, with apex wider than base.
Pronotum
(
Figure 2
(a)) transverse, slightly wider than long; surface moderately setose, similar to head, with conspicuous, decumbent pale setae. Secondary sublateral line present between sublateral line and lateral margin; secondary line completely effaced at posterior half. Anterior angles weakly acute and slightly produced anteriorly. Posterior angles obtuse.
Elytra
(
Figure 1
(a)) 3.2 times longer than wide, with sides strongly declivous; pubescence similar to pronotum and head, with longitudinal rows of moderate setae.
Thoracic venter
. Procoxal cavities posteriorly closed. Prosternal process broad, twice wider than long, with apex slightly curved.
Abdomen
. Intercoxal process broad, as wide as metacoxa, with apical margin slightly curved.
Genitalia
(
Figure 2
(e)). Tegmen broadly rounded at base and slightly constricted at middle; apex moderately setose, with setae moderate in size; apical angles with a long seta. Parameres small, conspicuous only at middle, conjunctly triangular, with sharply acute apex.
Variation
One of the male
paratypes
has the internoapical projection of antennal scape slightly narrower than all the other specimens including the
holotype
.
Female.
Unknown.
Etymology
The specific epithet refers to the
type
locality, the city of Pederneiras,
São Paulo state
,
Brazil
.

Remarks
This species is similar to
C. spectabilis
in the form of the antennal scape, which bears a conspicuous, internally deflected apical process in males, and in the presence of pronotal secondary sublateral lines.
Cryptolestes pederneirensis
sp. nov.
, however, can be easily distinguished by (characters of
C. spectabilis
in parentheses): body surface covered by conspicuous, decumbent setae (body pubescence inconspicuous, with minute setae); elytral surface light testaceous (piceous); internoapical process of male scape cylindrical, broadly rounded, with an apical tuft of setae (internoapical process of male scape strongly flattened, scoop-shaped, and sparsely setose apically); male pedicel globose, untoothed (male pedicel with an internoapical tooth); and male genitalia as in
Figure 2
(e) (male genitalia as in
Figure 2
(f)). The male genitalia of the new species is similar in shape to that of
C. unicornis
, but the latter can be easily identified by the narrow, hook-shaped internoapical process of the male scape. The endophalli of all dissected
paratypes
of
C. pederneirensis
sp. nov.
were damaged during dissection and could not be described.
Biology
All the specimens composing the
type
series were collected under bark of a dead trunk of
Dimorphandra mollis
(
Fabaceae
) along with individuals of
C. unicornis
and
C. punctatus
.
