Type material. HOLOTYPUS, female: China: Guangxi, / Dayao Shan Mt. , / 05.2020./ local collector leg. [handwritten]; // HOLOTYPUS:/ Procleomenes / medinai sp. nov. / A. Bar š evskis descr. 2022 [red label, handwritten] ( DUBC) .

General distribution: China: Guangxi.

Description. Body length: 6.6 mm, body width: 1.3 mm. Dorsal surface dark. Elytra flat, shiny, with three transverse somewhat transparent bands.

Head small, quadrangular, transverse, flattened, with sparse pubescence and fine microsculpture. Eyes large, extended. Cheeks narrow, not extended,with sparse pubescence. Head between antennal bases with wide deep impression. Clypeus narrow, shiny, with transverse deep impression in basal part. Labrum brown, shiny, with yellow setae. Mandibles brown, wide, shiny, with very acute apices. Maxillary palpomeres brown. Antennae dark­brown. Basal antennomere elongate and thickened, with fine microsculpture and relatively short setation; antennomere 2 short, yellow, covered with fine setae; antennomeres 3–4 yellow in basal portions, dark­brown in apical portions, covered with pubescence; remaining antennomeres unicolor dark­brown. Inner sides of all antennomeres with row of some long setae.

Pronotum elongate, subcylindrical, with dorsaland lateral tubercles. Length: 1.6 mm, width: 0.7 mm before tubercles and 1.1 mm with lateral tubercles; anterior and posterior borders prominent; pronotum distinctly longer thanwide. Pronotal disc with a pair of lateral protruded tubercles and five dorsal tubercles. Pronotum shiny, with very fine microsculptureand very fine, sparse, coarse punctation in middle; lateral portionsswith numerous long setae. Pars stridens partly visible under basal margin ofpronotum, emargined with impressed lines laterally.

Dorsal surface of elytra flat, shiny, without pubescence, dark, with three transverse almost transparent bands. Elytra narrowing in about middle and slightly broadened posteriorly; apical margin of elytra not reaching apex of abdomen. Apices of elytra truncate, brown, with rudimental angles, not extended in sharp denticles. Anteromedian portions of each elytron with oval impression at base near suture, with very sparse and fine punctation; each puncture bearing a long yellow seta. Width of elytra at shoulders: 1.2 mm. Length of elytra: 3.1 mm. Surface of elytra with fine rows of relatively sparse punctures. Ventral surface of body smooth, with sparse punctation and, with irregular rudimental pubescence. Legs relatively long and thin, with thickened apical portions of femora. Widest part of femora black, otherportions yellow. Tibia dark­brown, flattened atexternal margin, with fringe of long setae. Tarsomeres yellow, covered by sparseand golden pubescence.

Male unknown.

Differential diagnosis. Procleomenes medinai sp. nov. with a relatively dark surface is similar to P. morio Holzschuh, 2007 , known from Laos, but differs from it by the different surface pattern. The first postbasal transverse transparent band of a new species is broad and triangular, from the base of the elytra at the scutellum almost extending the lateral margin, enclosing the dark shoulder (this band of P. morio is smaller, narrower, not reaching the base and lateral margin, does not surround the shoulder). Remaining second and third dorsal tranverse bands of a new species are very narrow (relatively broader in P. morio ).

Etymology. This species is named after my friend and excellent colleague, Philippine entomologist Dr. Milton Norman Medina (Davao Oriental State University, Philippines) in appreciation of friendship, excellent cooperation, and in gratitude for his contribution to the studies of Coleoptera in the Philippines.
