Microscapha andrzeji Bukejs et Alekseev 2015
No full text<i>Microscapha andrzeji</i> Bukejs et Alekseev, 2015 <p> <b>Material examined.</b> One specimen with collection number MMO 1 7657/1265 [MWO]; Baltic amber, adult, female, complete specimen. The beetle inclusion is preserved in a small, yellow, polished piece of transparent amber with dimensions of 12×10× 4.5 mm without supplementary fixation. Syninclusions are represented by one Acari specimen.</p> <p> <b>Note.</b> The specimen is unicolorous rufous, with body length 1.71 mm, body width 0.79 mm (body length/width ratio 2.18), with sutural stria reaching scutellar shield and scutellar sides straight. The characters correspond to the described <i>M. andrzeji</i> with the exception of the body coloration. The holotype of <i>M. andrzeji</i> is dark brown, with maxillary palpomere 4 and antennomeres 9–10 rufous only, while the specimen under study is unicolorous rufous (like the holotype of <i>M. kugelanni</i> <b>sp. nov.</b>). The color difference between the studied amber specimens is considered insignificant for species attribution in this case and possibly caused by the fossilization of amber and alteration of inclusions after burial.</p>Published as part of <i>Alekseev, Vitalii Igorevich & Bukejs, Andris, 2021, Fossil Melandryidae (Coleoptera: Tenebrionoidea) from Eocene Baltic amber of the Sambian peninsula: new genus, six new species, new records and key to described taxa, pp. 142-166 in Zootaxa 4965 (1)</i> on page 162, DOI: 10.11646/zootaxa.4965.1.7, <a href="http://zenodo.org/record/4723237">http://zenodo.org/record/4723237</a>

Patronymic. This species is named after Dr. Nathan P. Lord (Baton Rouge, Louisiana, U.S.A.) in honour of his valuable contributions to the study of Zopheridae. Distribution. The species occurs in eastern U.S.A., from New Jersey to Florida, and extends westward to reach eastern Oklahoma (Stephan 1989). Biology. The beetles live under bark and in rotting, moist wood of oak, hickory, and other hardwoods; they also occur rarely on pine (Stephan 1989).Published as part of Bukejs, Andris, Alekseev, Vitalii I., Cooper, David M.

Picemelinus irinae Alekseev & Grzymala, 2015, sp. nov.
No full textPicemelinus irinae sp. nov. Alekseev & Grzymala (Figs. 8–9) Material examined. Holotype No. 890 - 5 [CCHH], male (Figs. 8–9). The beetle inclusion is preserved in a polished piece of transparent amber with a yellowish shade without any further fixation. The piece is small, irregular in form, with maximum length 12 mm and maximum width 8 mm. The syninclusions are represented by two trichomes. Etymology. Matronymic, this new species is dedicated to the mother of the first author—Irina I. Alekseeva. Type strata. Baltic Amber. Eocene. Type locality. Russia, the Kaliningrad region, the Sambian [Samland] peninsula, Yantarny settlement [formerly Palmnicken]. Description. Length 1.8 mm; moderately convex, elongate. Unicolored, black. Upper surface biseriate, clothed with very short pubescence, one seta arising anterad of each puncture, with additional short, numerous setae between primary pubescence (pruinose pubescence). Body length 1.9 × maximum body width. Elytral length 3.6 × pronotal length. Head. Eyes large, oval, hemispherical, with slight anterior emargination, well-separated from hind margin of head; interocular space narrower than one ocular diameter; temples approximately 1 / 3 of minimum ocular diameter; apical maxillary palpomere elongate triangular; vertex covered by pubescence equal in length and width to elytral pubescence. Antenna (Fig. 8 B) filiform, 11 -segmented, pubescent, reaching middle of elytra when folded backward; scape, antennomere III, and antennomere XI longest; antennomere length ratios: 14 - 4-20 - 5 - 5-6 - 6 - 6 - 6 - 6- 11; antennomere III with two apical projections forming cavity for antennomere IV. Thorax. Pronotum (Fig. 8 A) transverse, width 0.7 × length, widest apically, with very shallow impression laterad of basal angle, disc with pubescence indistinct, punctation dense and coarse. Scutellum subquadrate, without visible punctation or pubescence. Elytron with short, simple pubescence, moderately convex, with slight depression on disc in basal third near suture; sides weakly rounded; width 0.7 × length; punctation dense and coarse; punctures finer towards lateral aspects of disc. Abdomen. Separation of abdominal ventrite I and abdominal ventrite II visible medially and laterally. Legs. Metafemur simple, without visible brush or comb of modified setae. Metatarsomere I length 3.0× metatarsomeres II–IV combined, metatarsomere II bilobed, metatarsomere III concealed. Diagnosis. Picemelinus irinae sp. nov. differs from the only extant described member of this genus from Japan, Picemelinus flabellicornis (Pic, 1910), by the simple instead of flabellate antennomeres V–X. The elongate scape and the very distinctive length and shape of antennomere III provide evidence for the congeneric status of these two species.Published as part of Alekseev, Vitalii I. & Grzymala, Traci L., 2015, New Aderidae (Coleoptera: Tenebrionoidea) from Baltic and Bitterfeld amber, pp. 239-257 in Zootaxa 3956 (2) on pages 244-245, DOI: 10.11646/zootaxa.3956.2.5, http://zenodo.org/record/23222

Abdomen with five visible ventrites; finely and densely punctured, distance between punctures equal to 0.5– 1.5× diameter of one puncture; ventrite 5 with very shallowly emarginated apical margin; ratio of relative lengths of ventrites 1–5 = 10:10:7:7:10 (medially). Remark. Metathoracic wings hidden. Forelegs, middle antennomeres and palpomeres are visible in contours only, perhaps due to preservation state of the specimen. Etymology. The epithet of this new species is patronymic. The species is named after Johann Gottlieb Kugelann (1753–1815), born in Königsberg, an entomologist who worked on Coleoptera of the region. Differential diagnosis. Microscapha kugelanni sp. nov. differs from the morphologically similar extinct M. andrzeji Bukejs et Alekseev, 2015 from Baltic amber by shorter and wider body, about 1.9× longer than wide (in contrast to about 2.2× longer than wide in M. andrzeji); in smaller body length (1.7 mm in M. andrzeji); more rounded sides of scutellar shield (straight in M. andrzeji); and anteriorly incomplete sutural stria.Published as part of Alekseev, Vitalii Igorevich & Bukejs, Andris, 2021, Fossil Melandryidae (Coleoptera: Tenebrionoidea) from Eocene Baltic amber of the Sambian peninsula: new genus, six new species, new records and key to described taxa, pp. 142-166 in Zootaxa 4965 (1) on page 150, DOI: 10.11646/zootaxa.4965.1.7, http://zenodo.org/record/472323

Apical portion of aedeagus as in Fig. 8C. Etymology The epithet of this new species (Latin adjective capillatus, meaning “hairy, long-haired, old-fashioned”) refers to its long, conspicuous dorsal pubescence. Differential diagnosis. Madelinia capillata sp. nov. differs from M. gedanoposita Alekseev et Pankowski, 2020 in: (1) shape of pronotum, lateral pronotal margins rounded, narrowed anteriad and posteriad; (2) distinctly longer and conspicuous pubescence of the dorsum; (3) slightly elongate scutellar shield (transverse in M. gedanoposita); (4) comparatively longer metatarsomere 2 (the ratio of metatarsomeres 1–2 in the new species consists 2:1, whereas the ratio in M. gedanoposita consists 4:1); and (5) smaller body (4.2 mm in contrast to 5.8 mm in M. gedanoposita). Note. The shape of pronotum and the body size can vary within certain limits in extant representatives of the tribe. The main diagnostic characters for species limitation within the extinct genus Madelinia is considered the pubescence, the shape of scutellar shield and the comparative lenghts of metatarsomeres 1–2.Published as part of Alekseev, Vitalii Igorevich & Bukejs, Andris, 2021, Fossil Melandryidae (Coleoptera: Tenebrionoidea) from Eocene Baltic amber of the Sambian peninsula: new genus, six new species, new records and key to described taxa, pp. 142-166 in Zootaxa 4965 (1) on pages 151-154, DOI: 10.11646/zootaxa.4965.1.7, http://zenodo.org/record/472323
