78199105FF87FFFDFF0BFB1DFA9EA528.taxon	etymology	Etymology. The species minor (latin: small) is named after its small size (forewing length 3.5 mm), smaller than P. electrobaltica (forewing length 4 – 5 mm) and P. eocenica (forewing length 5.2 mm)	en	Wichard, Wilfried, Wedmann, Sonja, Weiterschan, Thomas (2016): Spongillaflies (Neuroptera, Sisyridae) in Baltic amber.

78199105FF87FFFDFF0BFB1DFA9EA528.taxon	diagnosis	Diagnosis. Paleosisyra minor n. sp. comes with the traits of genus Paleosisyra and differs from P. eocenica and P. electrobaltica mainly by the male genitalia. The coxopodits are stocky and almost hemispherical, compared to the elongate and digitiform coxopodits of P. electrobaltica and to the “ long ” coxopodits of P. eocenica. The forewing venation is characterised by the 3 - branched RP in contrast to the 4 - branched RP in P. eocenica and P. electrobaltica. Three gradate series of cross-veins can be discerned (Fig. 1 b). The apical cross-veins are arranged in a more or less aligned outer gradate series. In the forewing of Paleosisyra minor n. sp., CuA runs to the wing margin with only two terminal branches and a final terminal fork. In the hindwing the sinusoid cross-vein rpma-mp originates from MP and enters RP + MA directly at the dichotomous branch (Fig. 2 b).	en	Wichard, Wilfried, Wedmann, Sonja, Weiterschan, Thomas (2016): Spongillaflies (Neuroptera, Sisyridae) in Baltic amber.

78199105FF87FFFDFF0BFB1DFA9EA528.taxon	description	Description. Head (Fig. 1 a): Antenna filamentous, two-thirds of the length of the forewings. Scapus distinctly larger than the other segments; pedicellus smaller, basally narrow and distally globular. The following 29 flagellomeres slightly longer than wide and approximately cylindrical. Maxillary palp 5 - segmented, with first, second and fourth segments shorter than the third; terminal segment triangular in dorsal view, twice as long as the third, broadest at base, narrowed and tapered at apex. Labial palps with third terminal segment enlarged, flattened, triangle-shaped, the second segment smaller than the terminal and than the narrow first segments. Dorsal region of the head capsule (vertex) slightly convex, on both sides large compound eyes well visible. Forewing (Fig. 1 b): Length 3.5 mm; membrane hyaline; costal area widened, costal cross-veins all simple, about 14 before the apical fusion between Sc and RA; subcostal area between Sc and RA with subcostal cross-vein sc-ra below the 2 nd costal cross-vein and above the dichotomous branch of RA and RP + MA, then followed by the dichotomous branch in RP and in MA below the 3 rd costal cross-vein. Between RA and RP cross-vein 2 ra-rp just placed basally of the dichotomous branch of RP in RP 1 + 2 and RP 3 + 4. The dichotomous branch of RP 1 + 2 in RP 1 and RP 2 is located close to the next cross-vein 3 ra-rp; RP 3 + 4 unbranched, simple; RP 3 - branched (RP 1, RP 2, RP 3 + 4), all 3 branches apically with short terminal forks. MA simple, divided apically into two short terminal branches; MP midway with dichotomous branch MP 1 + 2 and MP 3 + 4, both divided apically into two or three terminal branches. CuA and CuP separated from wing base; CuA running parallel to margin with two terminal branches and finally a terminal fork; CuP simple. Anal veins 1 A to 3 A all simple, running separately to anal margin. The area between RA and RP has three cross-veins: 2 ra-rp, 3 ra-rp and 4 ra-rp. Cross-vein 2 ra-rp participates in the inner cross-vein gradate series. Crossvein 3 ra-rp is connected to the middle cross-vein gradate series. The outer cross-vein gradate series consists of cross-veins running along the furcation of the terminal branches at the apical wing margin, including cross-vein 4 ra-rp of the area between RA and RP. Hindwing (Fig. 2 a): Costal cross-veins all simple and numerous before the apical fusion of Sc and RA; subcostal area between Sc and RA with a basal cross-vein. At wing base the stem of R hypothetically present and fused with MA; subsequently follows the dichotomous branch with RA and RP + MA; then MA separating from RP. Sinusoid cross-vein rpma-mp originating basally of MP and entering apically RP + MA directly at the dichotomous branch with separated RP and MA (Fig. 2 b). RP 2 - branched, separated in RP 1 + 2 and RP 3 + 4, all of them with terminal forks. MA and MP simple, with terminal forks. CuA with terminal branches, CuP simple. Anal veins (1 A, 2 A, 3 A) simple, running separately to anal margin. Apical cross-veins forming an outer gradate series. Male genitalia (Fig. 2 c, d): The outer genital structures are poorly preserved. The ectoproct is horseshoeshaped but largely covered by a white reflecting air film (verlumt), the gonocoxites (cp) heavily sclerotized, stocky and almost hemispherical; their inner sides slightly concave, apparently with a spacer to keep apart the gonocoxites. Ninth sternite (S 9) slightly sclerotized, V-shaped, wide angled, without any posterior processes.	en	Wichard, Wilfried, Wedmann, Sonja, Weiterschan, Thomas (2016): Spongillaflies (Neuroptera, Sisyridae) in Baltic amber.

78199105FF82FFFEFF0BFB0CFAA6A24C.taxon	diagnosis	Diagnosis. Paleosisyra electrobaltica Wichard et al., 2009 comes with the traits of the genus Paleosisyra and differs from P. m i no r n. sp. by the coxopodits which are elongate and digitiform, slightly curved ventrad. Compared with the description of the “ long ” coxopodits of P. eocenica Nel et al., 2003 the elongate and digitiform coxopodits of P. electrobaltica do not currently allow a significant differentiation. In the forewing of P. electrobaltica RP is 4 - branched. The apical cross-veins are arranged in a more or less aligned outer gradate series. CuA is running to the wing margin with 5 - 6 terminal branches and finally a terminal fork. In the hindwing the sinusoid cross-vein rpma-mp originates basally from MP and enters RP + MA apically close to the dichotomous branch. The residual distance to the dichotomous branch is a little longer than in P. eocenica and P. minor and distinctly shorter than in the Cretaceous Prosisyrina sukachevae.	en	Wichard, Wilfried, Wedmann, Sonja, Weiterschan, Thomas (2016): Spongillaflies (Neuroptera, Sisyridae) in Baltic amber.
