Differential diagnosis.
Cis lugowoji
sp. nov.
is allied to
Cis lineatocribratus
in the shape of the pronotum and the seriate punctures on the elytral disc. On average, however, it is smaller; moreover, it differs in its pronotal lateral margin, which, in the dorsal view, is visible over a greater length than in the latter species; the regularly convex clypeus without any transverse depression; in males by the fronto-clypeal ridge which is not armed with any projections, the oval patch on the first abdominal ventrite and the morphology of the male genitalia: the external processes of the tegmen extend almost to the middle of the subtriangular lobes of the internal processes, with the penis tapering more towards the top.
Description.
Holotype
.
♂ Measurements in mm: TL 1.45; PL 0.52; PW 0.57; EL 0,93; EW 0.66; GD 0.59. Ratios: PL/PW 0.91; EL/EW 1.41; EL/PL 1.79; GD/EW 0.89; TL/EW 2.20. Body (
Figs 13–14
) oblong; dorsal and ventral surface light brown with slightly paler pronotum and humeral neighbours of elytra; antennae, mouthparts, legs and other ventral sclerites yellowish brown; dorsal side at most without pubescence, sparsely distributed, short hairs visible only near anterior margin of pronotum and elytral apex; ventral side of body bearing very short, fine, sparsely distributed hairs which are inconspicuous and hardly visible under medium magnification (starting with
x40
). Head relatively exposed from pronotum, weakly convex; fronto-clypeal ridge not produced forwards; surface of head minutely punctate, shiny and slightly shagreened. Antennae 10-segmented; 3rd segment 1.85 times as long as 4th; 8th to 10th forming a loose club; CL/FL 0.737. Pronotum widest in the middle; anterior margin broadly rounded; anterior corners obtusely angulate, hind angles broadly rounded in lateral view (
Fig. 15
); lateral margins slightly reflexed and visible from above in basal three-quarters; sides nearly arcuate; dorsum irregularly, somewhat closely and conspicuously punctate; punctures uniform in size, rather small, separated by a distance equal to about 1–3 times their diameters; interstices between punctures reticulate. Scutellum small, subtriangular, shiny, with some inconspicuous punctures. Elytra sides slightly divergent from base to basal two-thirds, then rather sharply convergent apicad; surface strongly shiny; punctures on disc in dual size, the larger ones umbiliform, seriate, interstices between larger punctures in irregular rows separated by a distance equal to about 1–1.5 times their diameters; the smaller ones very shallow and inconspicuous. Prosternum in front of coxae medio-longitudinally carinate, transversely and somewhat deeply depressed before each coxa; presternal process rather narrow, subparallel-sided. Each protibia with the spinose apex outer apical angle. First abdominal ventrite bearing large, oval patch, densely setose, its greatest diameter one-third the length of the ventrite at the middle (
Fig. 14
).
Male genitalia and pregenital segment (
paratype
).
8th abdominal tergite with apical margin strongly rounded and armed with relatively long hairs (
Fig. 16
); 8th abdominal sternite subtrapezoidal, with apical margin deep emarginate in the middle, armed with relatively long hairs at the lateral corners (
Fig. 17
). Tegmen rather stout, expanding to the apex, apical internal processes expanded and subtriangular, longer than external processes (
Fig. 18
); penis distinctly extending to four-fifths the length, then tapers towards the apex. (
Fig. 19
).
Females
. Similar to males, but devoid of the abdominal sex patch.

Distribution and habitat.
The species is known only from the Talysh Mts. (
Azerbaijan
) (
Fig. 21
). All the specimens collected by the author were reared in
October 2011
from fruiting bodies of
Fomes
sp., growing on the trunk of oriental beech (
Fagus orientalis
).
Etymology.
I dedicate this new species to my friend, Jerzy Ługowoj (Hajnówka,
Poland
), a specialist in
Buprestidae
and
Cerambycidae (Coleoptera)
and my companion in many entomological expeditions.
