Diagnosis.
Cladophorus boceki
is closely related to
C. praecipuus
(
Fig. 4
) and both species are similar in the general appearance (
Figs. 21, 30
,
37, 47
). Despite their very low genetic divergence, these species are clearly defined by the length of antennal lamella 3 (
Figs. 7, 14
), the relative size of male eyes (ratio 1.55 and
2.02 in
C. boceki
and
C. praecipuus
, respectively) and
C. boceki
has a robust phallus with the gradually pointed apical part unlike
C. praecipuus
, which has the slender phallus, parallel-sided in four-fifths of its length (
Figs. 55–56, 73–74
).
Description.
Male. Body large,
13.6–14.1 mm
long, dark brown to black, elytra yellow, only apical 1/12 black (
Fig. 37
), transition between dark and light coloured parts of elytra abrupt, only elytral costae with slightly larger dark part (
Fig. 37
). Head small, with hemispherically prominent eyes, frontal interocular distance 1.52 times maximum diameter; antennae long, reaching two thirds of elytral length, flabellate, antennomere 3 with lamella 2.4 times longer than stem of antennomere, lamella attached to apical part of antennomere (
Fig. 7
). Pronotum transverse, 1.5 times wider than long at midline, lateral margins slightly elevated, frontal margin rounded, lateral margins bi-sinuate, frontal angles well marked, posterior angles sharply prominent, postero-lateral carinae weak (
Fig. 21
). Elytra flat, slightly widened posteriorly, transverse costae weak, partly covered by pubescence, elytral areoles slightly transverse (
Fig. 37
). Phallus robust, widest in apical third, gradually acuminate apically, with robust apical process (
Figs. 55–56
).

Etymology.
The species name is a patronym in honor of Matej Bocek (Olomouc).
