Nicotikis lackneri sp. nov.

Body ( Fig. 1) oblong, slightly convex medially, pitch-brown, shiny. Antennae and legs dark reddish-brown. Antennal club tomentose, with Vshaped sutures, sutures interrupted medially. Ratio of width of pronotum to head about 2.45. Frons almost flat, very finely and sparsely punctulate. Frontal stria of head complete, impressed and carinate medially. Labrum relatively wide, indistinctly emarginate anteriorly. Mandibles convex, finely but rather densely (0.5 - 1.0) punctulate.

Pronotal sides weakly arcuate and convergent on basal 2/3, thence acutely convergent forwardly. Marginal pronotal stria complete laterally ( Fig. 2). Outer pronotal stria well impressed and sinuate at sides, united with apical pronotal stria, the last one a little carinato-crenate. Basal end of outer lateral stria more or less distinctly prolongated along the pronotal base on about 1/ 6 - 1/5 of its length. Pronotal disc sparsely covered with fine ground punctulation, almost smooth at middle. Epipleura tristriate, besides of complete epipleural marginal and elytral marginal stria there is also a third complete stria. The last two ones subcariniform, all of them sinuate medially. Oblique and fine humeral stria present on basal 1/4. Subhumeral striae absent. First to 3rd dorsal striae complete and impressed. Fourth and fifth dorsal stria abbreviated basally, the 4th one present on apical 2/5, the 5th one on apical 1/5. Sutural stria present, reaching almost to midlength of elytra. All the dorsal striae crenate apically.

Propygidium ( Fig. 3) irregularly covered with ocelloid, large and round punctures, rather densely distributed (0.5 - 2.0). Pygidium almost smooth ore with some punctures medially, with very deep, enlarged fovea on each side, united basally by a row of large punctures.

Prosternal lobe broad and convex medially, its anterior margin rounded. Disc with several deep and round punctures at sides, rather distributed (0.2 - 0.5). Marginal stria complete. Prosternal process narrow, with two carinal striae united basally.Two lateral striae present, their outer edge carinate.

Mesosternum transverse and flat, its anterior margin emarginate. Marginal mesosternal stria bifurcate, interrupted medially and replaced here by a median mesosternal stria composed of three parts ( Fig. 4). Meso-metasternal suture fine. Intercoxal disc of metasternum with a little impressed median line, doubly margined laterally. Lateral metasternal disc densely covered with deep and semicircular punctures. Intercoxal disc of 1st abdominal sternum with two striae on each side, the outer one of them abbreviated basally.

Protibia with 5 spiny dents on outer margin and a pair of spines at inner angle. Mesotibia with 4- 5 dental spines on outer margin, sometimes some of them doubled, especially the apical ones. Apex of mesotibia with 4 spines. Metatibia with 3-4 dental spines on outer margin and with 5 spines on apical one. Meso- and metatibial apical corner a little elongate, usually with two spines. Ventral surface of profemur alutaceous, covered with distinct punctures, moderately densely distributed (0.5 - 1.5).

Male genital structures as figured ( Figs. 5 - 8).

Length.PE: 2.8 - 3.3 mm, total: 4.0 - 4.5 mm. Width: 1.8 - 2.1 mm.
