sp. nov.
(
Figures 2
a-c)
Description. Male
. Length 17.0 mm (measured from vertex to elytral apices), width 7.0 mm (measured across humeri). Habitus as in
Fig. 2a
. General form elongate-ovate, robust, moderate-sized. Integument ferrugineous with off-white and light brown pubescence.
Head with frons elongate, about 3 times width of lower eye lobe (
Fig. 2c
). Eyes with lower lobes small, ovate-oblong; narrowest area connecting upper and lower eye lobes about 2-3 ommatidia wide. Genae elongate, about 1.5 times taller than lower eye lobes.
Antennae about twice as long as body; antennal tubercles prominent, narrowly separated, contiguous at base; tubercles armed at apex with short blunt tooth; scape robust, gradually clavate, about 2/3 as long as antennomere III, a little shorter than IV; basal 2/3 of scape transversely rugose; antennomere III slightly sinuate; antennomeres V-IX about equal in length; antennomere X slightly longer than IX, subequal to XI.
Pronotum distinctly conical, wider at base, transverse, about 1.5 times as wide as long, sides nearly straight, without lateral protuberances (
Fig. 2a
); disk tumid, with three moderately elevated tubercles, median tubercle small, oval, lateral tubercles larger, traversed by a shallow, oblique, linear impression; entire disk coarsely, moderately punctate.
Scutellum transverse, sides straight, oblique, apex feebly emarginate.
Elytra about 1.6 times as long as width at humeri (
Fig. 2a
), about 3.5 times as long as pronotal length, about 1.4 times broader basally than pronotum at widest (at base); sides nearly straight, slightly sinuous, attenuate to apices, elytral apices individually rounded; base of each elytron with an elongate, moderately distinct gibbosity; basal 1/3 of elytra with moderate punctation, surface coarsely granulatepunctate; humeri prominent, without distinct crest, anterior margin arcuate, oblique, angle with large tubercle which is obliquely truncate at apex.
Venter with procoxae large, globose, anteriorly with a robust, short uncus; narrowest area of prosternal process between procoxae about 1/5 as wide as procoxal cavity; apex of prosternal process subtriangular. Mesosternal process about as wide as mesocoxal cavity; deeply emarginate. Fifth sternite about 1.5 times as long as IV, apex feebly emarginate.
Legs moderate in length; profemora robust, transversely rugose basally; meso- and metafemora clavate apically; tibiae expanded apically; metafemora about 1/3 as long as elytra.
Female
. Unknown.
Type Material
.
Holotype
, male (
Fig. 2
a-c), “Venez.a [sic], 26167, Fry Coll. 1905.100” (
BMNH
).
Etymology
. This species is named for Kelly B. Miller, for his friendship and camaraderie in the field, and for his many contributions to the study of
Coleoptera
. 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: humeri without distinct crest; sternites I-IV not glabrous at center; and relatively drab coloration.
Lesbates milleri
is most similar to
L. carissima
(
Fig. 2d
) but can be distinguished by the moderate punctation at basal1/3 of elytra (dense in
L. carissima
); basal 1/3 of elytra with surface coarsely punctate (granulate-punctate in
L. carissima
); and the pubescence of sternites I-IV at center (glabrous at center in
L. carissima
).This species is described from a single male specimen and female specimens are unknown. Nothing is known about the habitat and behavior of this species. The geographic range of this genus (previously known only from
Brazil
) is extended to
Venezuela
.
