Diagnostic description
Length: 2.0mm, width: 1.5mm; body elongate oval, weakly convex, glabrous; color rufopiceous to piceous, with faint metallic sheen; head with frons flat, wide, ground punctation fine, secondary punctures sparse with only few coarser punctures dorsad, frontal stria present only along inner margin of eye, obsolete across middle, supraorbital stria present, meeting frontal stria at sides; antennal scape short, club nearly circular; epistoma straight to faintly emarginate apically; labrum about 4×wider than long, weakly emarginate apically; both mandibles with strong, acute basal tooth; pronotum with sides weakly convergent, rounded to apex, lateral marginal stria descending to ventral edge in posterior half, continuous anteriorly with complete anterior marginal stria, lateral submarginal stria present in basal three-fourths, pronotal disk weakly depressed in anterolateral corners, with fine ground punctation, conspicuous secondary punctures interspersed more or less throughout, slightly denser toward sides; elytra with two complete epipleural striae, outer subhumeral stria absent, inner present in basal one-fourth or less, dorsal striae 1-4 complete to base, progressively shortened apically, 4th stria distinctly arched to sutural in front, stria 5 slightly abbreviated at base and apex, sutural stria present in middle one-fourth, abbreviated at base and apex, elytral disk with scattered secondary punctures in apical one-third; prosternum moderately broad, keel weakly emarginate at base, with carinal striae shortened, joined in anterior arch near midpoint; prosternal lobe about two-thirds keel length, apical margin bluntly rounded, with marginal stria present only at middle; mesoventrite weakly produced at middle, with marginal stria complete or weakly interrupted at middle; mesometaventral stria arched forward, subangulate at middle, continuous laterally with inner lateral metaventral stria, which extends straight posterad to inner corner of metacoxa, outer lateral metaventral stria present, parallel to inner stria, complete; metaventral disk coarsely punctate at sides, impunctate at middle; abdominal ventrite 1 with two complete lateral striae, disk with coarse secondary punctures at sides and in posterior corners of middle portion, ventrites 2–5 with sparse secondary punctures at sides, the punctures becoming sparser and finer at middle; protibia tridentate, the middle tooth closer to apical than basal, outer margin serrulate between teeth; mesotibia with two very weak marginal spines; outer metatibial margin smooth, edentate; propygidium lacking basal stria, with sparse, fine ground punctation, with coarse secondary punctures evenly interspersed, propygidial gland openings narrow, obliquely elongate, located about one-third behind anterior margin, about one-fourth width from each lateral margin; pygidium with sparse ground punctation and slightly coarser, secondary punctation denser toward base. Male: not known.
Remarks
The holotype of Baconia kubani was initially identified as a specimen of Baconia barbarus, and they are very similar. However, a combination of characters distinguish it quite clearly: more uniform pronotal punctation (Fig. 49G), slightly more abbreviated elytral striae, presence of two complete lateral metaventral striae, and shortened prosternal carinal striae that are united at the middle of the prosternal keel (Fig. 49H). In fact the united prosternal keel striae are shared only with Baconia adebratti, which is easily distinguished by the inner metaventral stria curving strongly mediad posteriorly.
Etymology
We name this species in honor of its collector (as well as one other new species treated here), the Czech buprestid specialist Vítězslav Kubáň.
