Balticopteryx dui gen. et sp. nov., by monotypy.</p><p>Diagnosis. Diagnostic characters of the new genus Balticopteryx include: 1) body size extremely small, about 6.0 mm in length; 2) biocellate, each ocellus small and distant to each other; extremely long antennae, with about 50 segments; 3) wings without characteristic patterns, veins simple; RP, M and CuA of forewing each with two branches; only a single h vein presents in the costal area; 4) coxal gills absent; three tarsal segments equal in length; 5) sternum 8 mostly membranous, posteriorly with a small genital opening, anterior of the opening forming a sclerite; 6) postgenital plate elongated and pointed distally, exceeding part of the paraprocts; 7) cerci sixsegmented, apical segment unmodified.</p><p>The new genus is readily assigned to the family Taeniopterygidae because of the clear presence of three tarsal segments equal in length (Stewart &amp; Stark 2008, Teslenko &amp; Zhiltzova 2009, Chen &amp; Du 2018). Based on the wellproduced postgenital plate and the absence of coxal gills, this genus belongs to the subfamily Brachypterainae (Ricker &amp; Ross 1975) . In Taeniopterygidae, only the genus Kyphopteryx Kimmins, 1947 lacks the anterior ocellus; only in Doddsia Needham &amp; Claassen, 1925 and Mesyatsia Ricker &amp; Ross, 1975, the anterior ocellus tends to be smaller than normal (Ricker &amp; Ross 1975, Zhiltzova &amp; Zwick 1993). The complete absence of anterior ocellus in Balticopteryx has excluded its recognition as other taeniopterygid genera except for Kyphopteryx . Apart from the number of ocelli, other comparisons are made between Balticopteryx and the three above mentioned genera, Kyphopteryx, Doddsia and Mesyatsia .</p><p>In the three species of Kyphopteryx, the hind wing is exceptionally triangular, which is in normal shape in Balticopteryx (see figs. 623, 625 in Teslenko &amp; Zhiltzova 2009 and fig. 1B in Kimmins 1946); RP has three branches in both wings, which has only two in Balticopteryx; wings have more irregular crossveins especially in subapical section, while the wing venation is simple in Balticopteryx; the 8th sternum of female is completely or partially sclerotized with a notch on posterior margin (see figs. 622, 624 in Teslenko &amp; Zhiltzova 2009 and fig. 3G in Kimmins 1 946), which is mostly membranous in Balticopteryx with a small posterior genital opening. In the only species of the Nearctic Doddsia, Doddsia occidentalis (Banks, 1900), there are additional costal crossveins and more branches of RP and CuA in forewing (see fig. 3 of plate 33 in Needham &amp; Claassen 1925); the sternum 8 is cleft at posterior half and the postgenital plate is beyond the abdominal tip (see fig. 1 of plate 46 in Needham &amp; Claassen 1925), but in Balticopteryx, the sternum 8 is almost complete, and the postgenital plate is much shorter, only covering part of the paraprocts. In Mesyatsia, there are two to four costal crossveins including the humeral crossvein in the forewing (Ricker &amp; Ross 1975, Teslenko &amp; Zhiltzova 1992, 2009), but there is only one in Balticopteryx. In addition, the female of Balticopteryx exhibits a much smaller body size of about 6 mm. In the other three genera, body size is generally over 10 mm in females.</p><p>Etymology. The genus name Balticopteryx refers to the holotype collection locality, Baltic.</p></div>	https://treatment.plazi.org/id/055B87DDFFD25242FF79FDD8E4C5F95D	Public Domain	No known copyright restrictions apply.

Biocellate, each ocellus small and distant to each other; compound eyes pale in current status, not enlarged. Antennae dark and filiform, with about 50 segments. Maxillary palp threesegmented, each segment equal in length.</p><p>Thorax (Figs. 1, 3): Pronotum subquadrate, anterior margin sinuous. Coxal gills absent; sclerotized coxal extensions present instead. Legs mostly dark brown; hindlegs longest, about 1.5× longer than forelegs and midlegs; tibia with two giant ventroapical spurs; tarsus three-segmented, each segment almost equal in length; claws hooklike and sharp.</p><p>Wings (Figs. 1, 2, 4): Wings smoked, without any diagnostic patterns; veins dark brown. Forewing length ca. 7.0 mm; ScP reaches RA before ra-rp, apically approaching the anterior margin of forewing; only a single h vein presents in the costal area; a very pale crossvein presents in apical area; RP, M and CuA each forked with two branches; area between M and CuA with five crossveins in right forewing, and with four crossveins in left forewing; area between CuA and CuP with five crossveins in right forewing, and with seven crossveins in left forewing; AA1 simple, AA2 forked. Left hindwing length ca. 6.0 mm; ScP similar to that of forewing; RP and M each forked with two branches; crossveins r, r-m, m, and cu present; AA1 simple, basal area invisible.</p><p>Abdomen (Figs. 2, 5): Dorsal aspects invisible. Segments generally pale brown, sterna 1–7 each with a kidney-shaped dark sclerite. Sternum 8 mostly pale, lateral margins dark; posteromedial margin of sternum 8 with the opening of the oviduct, anterior margin of the genital opening darkly sclerotized and semicircular. Sternum 9 mostly sclerotized, medially with an elongated postgenital plate, which is slightly pointed distally and exceeding basal half of the paraprocts; lateral margin of postgenital plate with several hairs. Cerci composed of six segments, apical segment unmodified.</p><p>Egg (Fig. 1): An isolated, dark brown and subrounded egg presents near the female and without obvious modifications, which might be the egg of this female.</p><p>Holotype. Female, a well-preserved specimen in a piece of Baltic amber from Lithuania (Eocene, ca. 40-50 Mya). The holotype is deposited in the Chen Amber Collection, Yangzhou, China, No. CZT-PLE-BA4.</p><p>Etymology. The new species is named for Professor Yu-Zhou Du from Yangzhou University, Yangzhou, China, who has contributed much to the knowledge of Chinese stoneflies.</p><p>Syninclusions. Unidentified Diptera, Coleoptera, a presumptive stonefly egg near the female adult and another two different unknown eggs.</p><p>Remarks. The shape of the presumptive egg of Balticopteryx dui is similar to another taeniopterygid, Brachyptera risi (Morton, 1896), the egg of which is also ovoid without conspicuous anterior and posterior poles (Michalik et al. 2015). Eggs of family Taeniopterygidae are seldomly studied in the past and may be contribute useful information in comprehensive taxonomic identifications.</p><p>Liu et al. (2007) described two new Middle Jurassic fossil genera of Taeniopterygidae from Daohugou Village, Inner Mongolia, China. The wing venation of both genera are simple, supporting the hypothesis of Ricker &amp; Ross (1975) that the ancient species of the family possess simpler venation than more recent species. The simple venation of the new genus described in this study also supports this hypothesis from an Eocene view.</p></div>	https://treatment.plazi.org/id/055B87DDFFD25240FF79F8A6E500F90F	Public Domain	No known copyright restrictions apply.
