sp. nov.
(
Figures 1a–d
)
Description. Female
. Length 25.0–27.0 mm (measured from vertex to elytral apices), width 10.5–11.0 mm (measured across humeri). Habitus as in
Fig. 1a
. General form elongate-ovate, moderate to largesized. Integument ferrugineous or dark brown, entire body (except antennae and legs) with tawny pubescence, mottled with dark brown maculae of various sizes; elytra with two large, dark brown, irregularly-shaped maculae near middle.
Head with frons elongate, about 3/4 times width of lower eye lobe (as in
Fig. 1c
). Eyes with lower lobes large, ovate-oblong. Genae subquadrate to trapezoidal, distinctly shorter than lower eye lobes.
Antennae about 1.3 times longer than body; antennal tubercles prominent, narrowly separated, contiguous at base; tubercles armed at apex with small, blunt tubercle; scape robust, slightly bowed, gradually expanded to apex. Antennal formula based on antennomere III: scape=0.80; II=0.06; III=1; IV=0.81; V=0.63; VI=0.59; VII=0.53; VIII=0.45; IX=0.45; X=0.45; XI=0.45.
Pronotum roughly conical, distinctly wider at base, transverse, about 1.5 times as wide as long, sides feebly arcuate (
Fig. 1d
); disk at middle near base with a feebly elevated, median tubercle, either side of middle with three blunt tubercles arranged in a triangle; one apical and one transverse sulcus, and a more distinct oblique sulcus laterally which continues down the side.
Scutellum transverse, apex rounded.
Elytra about 1.75 times as long as width at humeri (
Fig. 1a
), about 4.5 times as long as pronotal length, about 1.6 times broader basally than pronotum at widest (at base); sides slightly sinuate, distinctly attenuate to apices, elytral apices individually rounded; base of each elytron somewhat gibbose, gibbosities each with prominent granules, rest of base with minute scattered granules, widely separated punctures placed one in each dark brown pubescent spot; humeri prominent, anterior margin oblique, the angle with a moderate-sized shining tubercle; sides below humeri with a few small granules.
Venter with procoxae large, globose, not uncate; narrowest area of prosternal process between procoxae about 1/4 as wide as procoxal cavity; apex of prosternal process subtriangular. Mesosternal process about as wide as mesocoxal cavity; mesosternal process deeply emarginate. Fifth sternite nearly 2 times as long as IV, with a median triangular impression.
Legs moderate in length; femora robust, gradually expanded to apex; tibiae slightly expanded apically; metafemora about 1/3 as long as elytra.

(measured across humeri). Similar to female except antennae 1.5 times longer than body; antennal tubercles armed at apex with short, blunt horn; pronotum widest behind middle, about 1.3 times as wide as long; elytra about 4 times as long as pronotal length; larger specimen with profemora transversely rugose; fifth sternite without a median triangular impression.

Etymology
.
Jamesia ramirezi
,
sp. nov.
is named for Rolando Ramírez Campos, for his collaboration and who collected part of the
type
series. The epithet is a noun in the genitive case.
Diagnosis and Remarks.
This species is distinguished from its congeners by the combination of the following characters: antennomeres I, II, basal 5/6 of III, and basal 2/3 of IV with grayish pubescence, distinctly lighter than V-XI, which are uniformly dark brown;
and elytra with red-orange pubescence, with small and moderately sized, dark brown maculae outlined with ring of white pubescence.
Swift et al. (2010)
listed three species of
Jamesia
from
Costa Rica
.
Jamesia ramirezi
,
sp. nov.
is described from
eight specimens
:
five males
and
three females
. Nothing is known about the habitat and behavior of this species
;
however, all known specimens were collected in
Costa Rica
, above
100 m
elevation (
three specimens
at
700 m
elevation)
.
