DESCRIPTION.
Male
. Dark brown; palps, except ultimate palpomeres, testaceous; narrow pronotal margins light brown testaceous (
Fig. 2
).
Vertex with shallow round impression and two small round pits behind antennal prominence. Eyes relatively large, interocular distance ca. 1.4 times shorter than eye diameter. Labrum small, transverse, anteriorly emarginate medially. Palps slender; ultimate palpomeres small, elongate, widest in proximal third, obliquely truncate and flattened at apex. Antennal sockets separated by minute lamina. Antennae attaining to elytral three fourths, antennomeres 4–8 serrate; antennomere 3 ca. 2.4 times longer than antennomere 2 and ca. 1.4 times shorter than antennomere 4; antennomeres 3–11 with scarce, relatively long erect pubescence (
Fig. 2
).
Pronotum transverse, ca. 1.6 times as wide as long, trapezoidal, slightly bisinuate basally and semi-circularly produced anteriorly, with slightly concave sides, long acute posterior and inconspicuous blunt anterior angles. Scutellum subquadrate, slightly narrowing distally, emarginate at apex (
Fig. 2
).
Elytra long, ca. 3.5 times longer than wide at humeri, parallel-sided, with four equally developed primary costae; interstices with even rows of small subquadrate cells; pubescence short and decumbent (
Fig. 2
).
Median lobe of aedeagus relatively short and robust, curved and dilated distally, with prominent toothed lobes in distal third (
Figs 17–18
).

ETYMOLOGY. The name of the new species is derived from the Latin for ‘short tail’, alluding to the shape of its aedeagus.
DIAGNOSIS.
Plateros curticauda
sp.n.
, being somewhat similar to
P. lalui
Tvardik et Bocák,
2001
in the shape of the male genitalia, is easily separable by the dark brown to black upperside, as well as by the more robust median lobe of the aedeagus with more prominent distal toothed lobes (
Figs 17–18
).
