Xenicotela pardalis
(Bates, 1884))
Redescription.
Body small, elongated. Eyes coarsely faceted. Antennae slender, more than 2.0 times as long as body in male and nearly 2.0 times in female; several basal antennomeres sparsely fringed ventrally, antennomeres III-XI annulated with greyish white to greyish yellow pubescence basally and apically; antennal tubercle moderately elevated; scape short, rather robust, with a narrow and completely closed cicatrix at apex, distinctly constricted near the apex; antennomere III distinctly longer than fourth, about 2.0 times as long as scape. Pronotum broader than long, anterior and posterior margin with vague transverse grooves, each side with a coniform spine at middle. Elytra elongated, with subparallel sides, apices rounded. Prosternal process lower than procoxae, arched, procoxal cavities closed posteriorly. Mesosternal process obliquely sloping anteriorly, not tuberculate, mesocoxal cavities open at side. Metasternum normal in length. Legs moderately long, femora clavate, mesotibia without groove near external apex, claw widely divergent.
Distribution.
Japan, South Korea, China, Vietnam, Laos, Nepal, India.
Comments.
The genus is characterized by the following combination of characters that distinguishes it from similar genera: antennae with basal several antennomeres (usually five segments) sparsely fringed with short setae ventrally, antennomeres III-XI annulated with greyish white to greyish yellow pubescence basally and apically; scape with a narrow and completely closed cicatrix at apex and distinctly constricted before it; lateral spine of pronotum coniform, short; mesosternal process obliquely sloping anteriorly, not tuberculate; mesotibia without groove near external apex.
Aurivillius (1922)
placed the genus
Xenicotela
in the tribe
Dorcaschematini
. Subsequently,
Matsushita (1933)
defined the tribe
Xenicotelini
for the genus according to the following differences on the basis of comparing with tribes
Ancylonotini
and
Prosopocerini
: scape with a completely closed apical cicatrix and mesotibia without a groove near the external apex.
Breuning (1943)
transferred the genus into Agninii, and
Gressitt (1951)
placed it in
Lamiini
.
Kariyanna et al. (2017)
and
Tavakilian and Chevillotte (2021)
followed
Matsushita's
decision and put the genus into
Xenicotelini
in their
Cerambycidae
database. In the present study, we follow
Breuning's
and
Gressitt's
arrangement, since the characters of
Xenicotela
correspond well with
Lamiini
.
