03F6C531FFDDB050FF429A8BC0BF8851.taxon	discussion	Taxonomic assignment. The inclusion examined shows a combination of external characters corresponding to the subfamily Endomychinae within the family Endomychidae: (1) elongate oval, convex body with pubescent dorsum, (2) 11 - segmented antennae with loose 3 - segmented antennal club, (3) discernible fronto-clypeal suture, (4) presence of two longitudinal sulci on the pronotum, (5) pronotum with broad lateral, raised margins, (6) postcoxal lines on abdominal ventrite 1 absent, (7) abdominal ventrite 1 longest, and (8) tarsi pseudotrimerous with lobed tarsomeres 1 and 2. The specimen considered here is assigned to the genus Danae Reiche based on a combination of the following morphological characters: (1) pronotum with broad, raised side margins (in contrast to extant Africanasaula, Saula and Tragoscelis or extinct Zemyna), and not distinctly narrower than elytral base (contrary to Africanasaula, Saula or Zemyna); (2) dorsum distinctly pubescent (in contrast to extant Endomychus with glabrous or very finely pubescent dorsum); (3) distinct transverse basal sulcus of pronotum (absent in Ectomychus); (4) elongate, loose antennal club, and elongate body form (antennal club rather short and compact, and comparatively more oval and more globose body in most species of Stenotarsus); (5) pronotal posterior angles not indented to receive the humeral portion of elytra (in contrast to Tharina); (6) elytra not striate, only with fine incomplete sutural striae (in contrast to deeply punctate-striate elytra in Paniegena); (7) lobed tarsomeres 1 – 2 (in contrast to feebly developed or absent lobation on the tarsomere 2 in Chondria); (8) anterior pronotal angles widely rounded and distinctly projecting anteriad (in contrast to acute anterior pronotal angles in Tragoscelis); (9) symmetrical antennal club (asymmetrical antennal club in Ectomychus); (10) comparatively long lateral sulci and basal sulcus without oval pit on each side (in contrast to short lateral sulci and basal sulcus with oval pits in Perrisina); (11) sutural stria discernible in posterior two-third of elytron and ovoid terminal antennomere with rounded apex (elytra with complete sutural striae and antennomere 11 obliquely truncate apically in extinct Mesozoic Cretostenotarsus). The non-modified antennomere 9 (not enlarged, toothed or excavate) could be interpreted either character of female sex of the specimen or probable absence of sexually dimorphic antennal structure in Eocene representatives of the genus.	en	Alekseev, Vitalii, Tomaszewska, Wioletta (2025): A new handsome fungus beetle of the subfamily Endomychinae (Coccinelloidea: Endomychidae) from Baltic amber of the Sambian Peninsula.

03F6C531FFDEB057FF429D46C0F88C13.taxon	materials_examined	Material examined. Holotype: No KAM 5726 / 6 [KRAM]; “ * Holotype / Danae sembanata / sp. nov. / Alekseev et Tomaszewska / des. 2025 ” [red handwritten label]; adult, sex unknown (probably female). Almost complete beetle (right fore and middle leg are missing) included in a small, transparent, yellow amber piece with dimensions of 17 × 13 × 6 mm and weight about 1.2 g; preserved without supplementary fixation. The specimen is covered with white opaque cloud on ventral surfaces of body and appendages, so-called ‘ Verlumung’ i. e. nontransparent, milky coloured amber with a high density of microscopic vesicles, caused by gas or liquid emulsion in non-hardened resin before polymerisation. Syninclusions: one specimen of Nematocera (Diptera), two specimens of Symphypleona (Collembola), one specimen of Acari (Arachnida) nymph, and several fagacean trichomes. Type locality. Southeastern Baltic Sea coast (Kaliningrad Region). Type horizon. Baltic amber, most probable from the Eocene amber-bearing layers of Blaue Erde (Blue Earth) within the Prussian Formation; estimated age: middle-late Eocene.	en	Alekseev, Vitalii, Tomaszewska, Wioletta (2025): A new handsome fungus beetle of the subfamily Endomychinae (Coccinelloidea: Endomychidae) from Baltic amber of the Sambian Peninsula.

03F6C531FFDEB057FF429D46C0F88C13.taxon	diagnosis	Differential diagnosis. The new species, Danae sembanata sp. nov., can be distinguished from the other representatives of the genus based upon the following combination of characters: dense and coarse punctation on elytral disc whereas elytral sides are rugosely punctate, antennomeres 9 - 11 distinctly elongate, subequal in length, with rather narrow antennomere 11, and well developed and comparatively long lateral sulci on the pronotum. Moreover, from the most similar, ‘ putatively’ closest Danae testacea (Ziegler), the new species differs by having less elongate, more oval body, the hind angles of the pronotum weakly acute (vs strongly acute in D. testacea), sutural stria on each elytron present along at least 2 / 3 of elytral length (present at most along 1 / 3 of elytral length in D. testacea), and antennomeres 9 – 11 distinctly elongate and subequal in length (vs antennomeres 9 and 10 shorter than terminal antennomere, and more transverse in D. testacea; additionally, despite a lack of strong dimorphism displayed in antennal club in D. testacea, antennomere 9 in male is weakly larger (longer and wider) than antennomere 10).	en	Alekseev, Vitalii, Tomaszewska, Wioletta (2025): A new handsome fungus beetle of the subfamily Endomychinae (Coccinelloidea: Endomychidae) from Baltic amber of the Sambian Peninsula.

03F6C531FFDEB057FF429D46C0F88C13.taxon	etymology	Etymology. The specific epithet sembanata is toponymic, a compound adjective derived from Semba (also Sambia or Samland, the historical area in the west part of the present-day Kaliningrad Region) and the Latin natus, - a, - um (born).	en	Alekseev, Vitalii, Tomaszewska, Wioletta (2025): A new handsome fungus beetle of the subfamily Endomychinae (Coccinelloidea: Endomychidae) from Baltic amber of the Sambian Peninsula.

03F6C531FFDEB057FF429D46C0F88C13.taxon	discussion	Note on the presumed palaeoecology of the fossil. The ecology of modern species of Danae has not been studied in detail. The widely distributed in the eastern US, the northernmost species of the genus, Danae testacea, occurs largely as a relict species in old-growth hardwoods and is associated with subcortical fungi in hardwoods and softer species of Polyporaceae (Majka 2007). For the fossil species, a similar biology, i. e. a mycophagous diet and dendrophilous mode of life in lower layer of the forest, can be assumed.	en	Alekseev, Vitalii, Tomaszewska, Wioletta (2025): A new handsome fungus beetle of the subfamily Endomychinae (Coccinelloidea: Endomychidae) from Baltic amber of the Sambian Peninsula.
