A191FCB25DAC59529608DB0F1FA27E5A.taxon	description	Description. Diagnosis: Small, markedly shiny ground beetle (due to reduced microsculpture on body surface), with nearly cylindrical body shape (Figs 11 - 14); pronotal marginal borders absent, very slender mandibles and maxillae, and with basal protarsomeres in male not widened. Head: Slender in its anterior part, robust from level of eyes towards base, with disc markedly convex, base broad and neck constriction absent (Figs 1, 15). Mandibles and maxillae notably long and slender, teeth on mandibular internal margin small, not prominent, markedly shifted basally, mandibular scrobe with seta (Fig. 17). Labrum with apical margin very slightly concave, with six setae near apical margin (Fig. 1). Clypeus with two primary setae on each side (Fig. 15). Anterior and posterior tactile supraorbital setae present (Figs 1, 15, 16); suborbital seta absent. Furrows on head disc shallow, very short, terminating posteriorly at level of anterior supraorbital setae (Figs 1, 15). Eyes moderately large, moderately protruded laterally; tempora short, about quarter of eye length, very slightly wrinkled towards the neck (Figs 15, 16). Antennae moderately slender, pubescent beginning from second antennomere; pedicellus about as long as scapus and third antennomere (Fig. 3). Ligula long and slender, with apex pointed, partly fused with paraglossae, latter distinctly protruded apically (Fig. 19); chaetotaxy of ligula not visible with the methods we used. Mentum with median tooth simple, with one pair of sharply defined pits; mentum and submentum separated by distinct suture; mentum with one pair of tactile setae laterally of apical tooth, submentum with two pairs of tactile setae in normal position (Fig. 18). Terminal maxillary and labial palpomeres about as long as penultimate palpomere, with shape slightly conical (Fig. 1); penultimate maxillary palpomere glabrous; penultimate labial palpomere glabrous except for two long setae in middle. Prothorax: Small, subcordate, with disc markedly convex, and with apical, basal and lateral borders absent (Figs 13, 14, 20; in CT images from some angles, such as that shown in Fig. 20, the shrunken exoskeleton and the negative imprint of the beetle on the inclusion wall may give the impression of existing border lines); anterior margin straight with lateral angles rounded, not protruded anteriorly; basal margin slightly convex in middle and with outer sixth markedly shifted anterad; laterobasal angles moderately large, obtuse, very slightly protruded laterally; anterior lateral seta situated near anterior end of second pronotal third, posterior seta situated at basal angle (Figs 8, 20). Median line on pronotal disc deep between anterior and posterior transverse impressions, absent near apex and base; anterior transverse impression distinct, complete; posterior transverse impression broad, marked by three large pits medially, and small, irregularly impressed laterobasal grooves laterally (Fig. 20). Prosternum coarsely punctate (Figs 12, 22); prosternal process short, widened towards truncated posterior margin (Fig. 22); procoxal cavities closed externally. Pterothorax: Elytra in dorsal view moderately ovate to sub-parallel, much broader than pronotum, with sides very slightly narrowed towards broad humerus (Figs 3, 8, 11, 26, 29, 36, 38, 41), in lateral and frontal or caudal views markedly convex towards disc, such that hind body is almost circular in cross-section (Figs 9, 13, 14, 21, 28, 30, 37, 39, 40, 42). Basal border absent from base of 5 th stria inwards (Fig. 11). Parascutellar stria abbreviated, connected with the first stria, parascutellar tactile seta present, situated at base of second stria (Fig. 11). Striae 1 - 9 slightly impressed in anterior 4 / 5 but markedly accented by rows of large and deeply engraved punctures (Figs 3, 8 - 11, 21, 29, 36, 41); punctures gradually less deep from anterior 1 / 9 towards base and posterior quarter towards apex, latter smooth beside the deeply engraved 1 st and 8 th striae, with recurrent stria absent and subapical setiferous pore " isolated " (the seventh and the internally adjacent striae are invisible) (Figs 2, 21); intervals convex on elytral disc, flat near elytral base and apex. Three discal setae present on each elytron; all are connected to the third stria, with anterior one located near end of anterior elytral 5 th, second located slightly anterior of elytral middle, and posterior one located slightly posterior of elytral 2 / 3 (Figs 9, 11). Umbilicate series consists of eight setae distinctly separated into three groups (Fig. 14): humeral group (four setae, with posterior one slightly more distant than setae 1 - 3), medial group (two setae, located distinctly behind elytral middle), subapical group (two setae). Elytral subapical plica present (Fig. 21). Hindwings fully developed. Mesoventrite and metaventrite near anterior margin coarsely punctate (Figs 12, 22); mesocoxal cavities conjunct; mesepimeron wide, metanepisternum long and slender, external lobe of metepimeron well developed (Fig. 22). Legs moderately robust, short (Fig. 12). Protibia with antenna cleaner anisochaetous Grade B (Hlavac 1971), with basal portion of cleaning channel flat, extending basad far beyond insertion of the clip setae, and with insertion of posterior spur very slightly distad of that of the clip setae (Figs 24, 25); protibial external surface smooth, without longitudinal groove, and with apicolateral surface obliquely excised (Fig. 23). Basal protarsomeres of males not dilated, not uniquely dentate (Fig. 23). Fifth tarsomeres of all legs ventrally smooth, without setae. Mesocoxa with one seta at external margin; metacoxae laterally not extended to elytral epipleuron, trisetose, with both the external setae distinctly removed from the coxal ridge; metatrochanter with a single seta (Fig. 22). Abdomen: Smooth beside primary setation: segments IV-VI with a single, VII with two pairs of setae near apical margin (Fig. 2). Male genitalia: Shape of the parameres of Trechitae type, nearly symmetrical, in general structure similar to parameres of Patrobini, markedly large, each with a long and slender apical apophysis which is more strongly sclerotized on its internal margin, with a large and almost discoidal middle portion, and with a heavily sclerotized basal portion (Figs 32 a-d, 35 a); chaetotaxy and membranous parts (e. g., those which probably connect apical and medial portions of the parameres externally) not recognizable. Median lobe moderately long and slender, in lateral view slightly sinusoidal in apical third (Figs 32 a, 33, 34 a), in dorsal view with its distal portion very slightly bent to the right (Figs 32 c, d, 34 b); apical lamella well-developed, almost as broad as median lobe. Dorsal surface of median lobe completely open: basal and apical ostia broadly connected across the dorsal median lobe surface, with separated lateral lobes of median lobe basal bulb (Figs 32 b, c).	en	Schmidt, Joachim, Scholz, Stephan, Maddison, David R.

A191FCB25DAC59529608DB0F1FA27E5A.taxon	etymology	Etymology. The generic name compounds the geographical term " Balticum " which is the origin of the amber where the new fossil lineage is preserved, and the Latin verb " celare " (concealing), and therewith refers to the specific circumstance that an odd lineage of ground beetles is hidden in Baltic amber.	en	Schmidt, Joachim, Scholz, Stephan, Maddison, David R.
