Differential diagnosis
.
Plateros mamasensis
sp. n.
posses characteristically curved apical part of phallus with dorsoapical groove (
Figs 3, 4
) similar to those of
P. rubromamasensis
sp. n.
(
Fig.
11
). These species differ externally in colouration and shape of antennae (
Figs 23, 26
). Serrate antennae of
P. mamasensis
sp. n.
remind
P. tanatorajensis
sp. n.
although antennomeral processes are apparently shorter in the former (
Figs 23, 27
).
Description
. Body small, slender, parallelsided, black, only pronotal margins light brown, legs brown, with dense light pubescence. Head small, eyes hemispherically prominent, interocular distance
1.13
times eye diameter. Antennae sharply serrate (
Fig.
23
), reaching two thirds of elytral length, apical antennomeres gradually narrower, antennomeres
1011
parallelsided. Antennae covered with long erected pubescence. Pronotum width at base
1.4
times length at midline. Pronotum slightly projected and widely rounded anteriorly, lateral margins straight, anterior angles distinct, posterior angles weakly projected (
Fig.
15
). Disc with two shallow but apparent rounded depressions, laterally to basal part of longitudinal midline. Disc shining, with long light pubescence. Elytra parallelsided,
3.6
times longer than width at humeri. Costae fine, covered with dense pubescence. Phallus curved in apical third, internal sac partly sclerotized (
Figs 3, 4
).
