Figs 2 View Figs 1–2 , 6, 7 View Figs 3–9 , 13, 14 View Figs 10–15 .

MATERIAL. Holotype, ♂, S Russia, Krasnodar Krai, Anapa Distr., env. Sukko , 28-30.IV.2018, leg. E.A. Khachikov leg. ( ICM); paratype, 1♂, same label ( ICM).

DESCRIPTION. Male. Dark brown to black; antennomere 1 and antennomere 2 proximally, knees and anterior tibiae apically testaceous; elytral middle third pale brown; elytral apices yellow ( Fig. 2 View Figs 1–2 ).

Head subquadrate, about as wide as pronotum. Eyes moderately large, spherical, interocular distance about as long as eye diameter. Vertex in scarce punctuation. Ultimate maxillary and labial palpomeres ca 3.7 times longer than wide. Antennae filiform, almost attaining to apices of folded wings; antennomeres 2 and 3 subequal in length and ca 1.3 times shorter than antennomere 4; antennal pubescence relatively short and semi-erect ( Fig. 2 View Figs 1–2 ).

Pronotum transverse, ca 1.2 times wider than long, widening anteriorly, with small acute posterior and truncate laterally developed anterior angles, convex anteriorly and posteriorly ( Fig. 2 View Figs 1–2 ).

Elytra elongate, ca. 2.3 times longer than wide at humeri, parallel-sided, leaving posterior third of folded wings uncovered; elytral pubescence uniform, short and sub-erect. Scutellum transverse, slightly narrowing distally, broadly rounded at apex ( Fig. 2 View Figs 1–2 ).

Legs long and slender; femora and tibiae narrow and straight, tibiae noticeably shorter than femora; hind tarsomere length ratio 4.5: 2.5: 1.8: 1: 1.5; tarsomere 4 deeply cleft; all claws simple ( Fig. 2 View Figs 1–2 ).

Ultimate sternite elongate, gradually narrowing distally, widened and deeply emarginate at apex, somewhat curved in lateral view; ultimate tergite elongate, slightly narrowed distally, with roundish incision at apex; penultimate tergite transverse, sub-rectangular; third from end tergite simple ( Figs 6, 7 View Figs 3–9 ).

Aedeagus roundish, with rounded distally dorsal plate; laterophyses in distal half relatively broad, parallel-sided, with almost rectangular bulges at base, in lateral view slanted outwardly, but not hooked at apex; penis strongly curved, in lateral view ( Figs 13, 14 View Figs 10–15 ).

Length (from head to apices of folded elytra): 3.0 mm; width (at humeri): 0.5–0.6 mm.

FEMALE. Unknown.

ETYMOLOGY. The new species is named after the type locality.

DIAGNOSIS. Malthodes sukkoensis sp.n. resembles M. pseudobesucheti Wittmer, 1970 , from the mountains of Krasnodar Krai and Abkhasia, differing in the relatively narrowly incised at apex ultimate sternite, shorter and not widened at apex ultimate tergite, more rounded dorsal plate of the aedeagus and not hooked apically, in lateral view, laterophyses ( Figs 6, 7 View Figs 3–9 , 13, 14 View Figs 10–15 ), vs broadly widened at apex ultimate sternite, longer and widened at apex ultimate tergite, more narrowed distally dorsal plate of the aedeagus and apically hooked laterophyses, in lateral view, in M. pseudobesucheti ( Figs 8, 9 View Figs 3–9 , 15 View Figs 10–15 , 48, 49 View Figs 38–49 , 87, 88 View Figs 81–92 ).

REMARKS. The paratype lacks head and pronotum.
