Of all known species of the Paraleptophlebia , new species on the structure of the ventral appendages of the penis lobes are closest to the following species: Paraleptophlebia cincta (Retzius 1783), P. debilis (Walker 1853), P. falcula Traver 1934, P. helena Day 1952, P. lacustris Ikonomov 1962, P. moerens (McDunnough 1924), P. ontario (McDunnough 1926), P. packii (Needham 1927), P. quisquilia Day 1952, P. strandii (Eaton 1901), P. strigula McDunnough 1932, P. westoni Imanishi 1937 and P. zayante Day 1952. New species differs from P. debilis (Harper & Harper 1986), P. moerens (Harper & Harper 1986), P. packii (Day 1952), P. strandii (Eaton 1901) and P. zayante (Day 1952) absent of large lobe at base of first segments of forceps. The same is known for the following species: P. cincta (Ulmer 1929), P. falcula (Traver 1934; Tiunova & Kluge 2016), P. lacustris (Ikonomov 1962), P. quisquilia (Day 1952), P. ontario (Burks 1953), P. strigula (McDunnough 1932; Burks 1953) and P. westoni (Imanishi 1937; Gose 1979 –1980). Male imago of Paraleptophlebia kunashirica sp. nov . can be distinguished by the following features: processes of styliger are not long (in contrast to P. falcula ) (Traver 1934; Tiunova & Kluge, 2016); ventral appendages slightly curved, extended and blunt distally (in P. cincta, P. lacustris, P. strigula and P. westoni ventral appendages slightly curved and pointed) (Ulmer 1929; Ikonomov 1962; Burks 1953; McDunnough 1932; Imanishi 1937); apex of each penis lobes rounded (in P. ontario and P. westoni apex of each penis lobes with conical construction, in P. quisquilia with a deep notch) (Burks 1953; Day 1952). Among species of Paraleptophlebia with available larval descriptions, Paraleptophlebia westoni differs from Nearctic species P. bicornuta (McDunnough 1926), P. helena , P. packii and P. zayante by absence of tusk-like elongation of mandibular incisor; from P. altana Kilgore & Allen 1973 and P. cachea Day 1954 it differs by nonwidened lobes of gills without dark lateral branches of main trachea. The same is known for the following species of Paraleptophlebia : P. calcarica Rowbotham & Allen 1988 (Jacobus & McCafferty2004), P. cincta (Macan 1952; Landa 1969), P. debilis (Ide 1930; Gordon 1933), P. falcula (Tiunova & Kluge 2016), P. guttata (McDunnough 1924) (Ide 1930; Gordon 1933), P. jeanae Berner 1955 (Randolph & McCafferty 1996), P. lacustris (Ikonomov 1962), P. moerens (Gordon 1933; Burks 1953), P. ontario (Needham, Traver & Hsu 1935; Burks 1953), P. praepedita (Eaton 1884) (Gordon 1933; Burks 1953), P. quisquilia (Day 1952), P. ruffoi Biancheri 1956 (Belfiore & Giangrande 1979), P. strandii (Tiensuu 1939), P. strigula (McDunnough 1932), P. submarginata (Stephens 1835) (Komarek 1921; Macan 1952; Landa 1969; Belfiore & Giangrande 1979), P. volitans (McDunnough 1924) (Ide 1930; Gordon 1933), P. werneri Ulmer 1920 (Landa 1969). Mature larvae of Paraleptophlebia westoni can be distinguished by the following features: thorax is not hairy (in contrast to P. volitans ); hypopharynx is slightly emarginated apically (Fig. 19) (in P. calcarica , P. lacustris and P. strandii have medioapical cleft); maxillary palp segments 3 slightly longer than segment 2, together 1.65 times longer than segment 1 (Fig. 18) (in P. debilis P. moerens P. submarginata, P. guttata and P. strigula segments 2 and 3 together are equal to segment 1); labial palp segment 2 is shorter than segment 3, and together nearly equal segment 1 (Fig. 19) (in P. falcula labial palp segments 2 is shorter than segment 3, and together are longer than segment 1); legs have no brown band (Fig. 22) (in contrast to P. debilis and P. jeanae ); row of denticles reaches middle or slightly more than the middle of the claw (Fig. 23) (in P. ruffoi and P. werneri row of denticles occupies more than half of claw); abdominal segment VIII and IX with posterolateral spines (in P. guttata and P. strigula lateral spines are present on segment 9 only). : Published as part of Tiunova, Tatiana M., 2017, A new species of Paraleptophlebia Lestage, 1917 (Ephemeroptera: Leptophlebiidae) and a re-description of adults for Paraleptophlebia westoni Imanishi, 1937 with the first description of the larva, from the Russian Far East, pp. 109-120 in Zootaxa 4337 (1) on pages 113-118, DOI: 10.11646/zootaxa.4337.1.5, http://zenodo.org/record/1014073 : {"references": ["Imanishi, K.

Of all known species of the Paraleptophlebia , new species on the structure of the ventral appendages of the penis lobes are closest to the following species: Paraleptophlebia cincta (Retzius 1783), P. debilis (Walker 1853), P. falcula Traver 1934, P. helena Day 1952, P. lacustris Ikonomov 1962, P. moerens (McDunnough 1924), P. ontario (McDunnough 1926), P. packii (Needham 1927), P. quisquilia Day 1952, P. strandii (Eaton 1901), P. strigula McDunnough 1932, P. westoni Imanishi 1937 and P. zayante Day 1952. New species differs from P. debilis (Harper & Harper 1986), P. moerens (Harper & Harper 1986), P. packii (Day 1952), P. strandii (Eaton 1901) and P. zayante (Day 1952) absent of large lobe at base of first segments of forceps. The same is known for the following species: P. cincta (Ulmer 1929), P. falcula (Traver 1934; Tiunova & Kluge 2016), P. lacustris (Ikonomov 1962), P. quisquilia (Day 1952), P. ontario (Burks 1953), P. strigula (McDunnough 1932; Burks 1953) and P. westoni (Imanishi 1937; Gose 1979 –1980). Male imago of Paraleptophlebia kunashirica sp. nov . can be distinguished by the following features: processes of styliger are not long (in contrast to P. falcula ) (Traver 1934; Tiunova & Kluge, 2016); ventral appendages slightly curved, extended and blunt distally (in P. cincta, P. lacustris, P. strigula and P. westoni ventral appendages slightly curved and pointed) (Ulmer 1929; Ikonomov 1962; Burks 1953; McDunnough 1932; Imanishi 1937); apex of each penis lobes rounded (in P. ontario and P. westoni apex of each penis lobes with conical construction, in P. quisquilia with a deep notch) (Burks 1953; Day 1952). Among species of Paraleptophlebia with available larval descriptions, Paraleptophlebia westoni differs from Nearctic species P. bicornuta (McDunnough 1926), P. helena , P. packii and P. zayante by absence of tusk-like elongation of mandibular incisor; from P. altana Kilgore & Allen 1973 and P. cachea Day 1954 it differs by nonwidened lobes of gills without dark lateral branches of main trachea. The same is known for the following species of Paraleptophlebia : P. calcarica Rowbotham & Allen 1988 (Jacobus & McCafferty2004), P. cincta (Macan 1952; Landa 1969), P. debilis (Ide 1930; Gordon 1933), P. falcula (Tiunova & Kluge 2016), P. guttata (McDunnough 1924) (Ide 1930; Gordon 1933), P. jeanae Berner 1955 (Randolph & McCafferty 1996), P. lacustris (Ikonomov 1962), P. moerens (Gordon 1933; Burks 1953), P. ontario (Needham, Traver & Hsu 1935; Burks 1953), P. praepedita (Eaton 1884) (Gordon 1933; Burks 1953), P. quisquilia (Day 1952), P. ruffoi Biancheri 1956 (Belfiore & Giangrande 1979), P. strandii (Tiensuu 1939), P. strigula (McDunnough 1932), P. submarginata (Stephens 1835) (Komarek 1921; Macan 1952; Landa 1969; Belfiore & Giangrande 1979), P. volitans (McDunnough 1924) (Ide 1930; Gordon 1933), P. werneri Ulmer 1920 (Landa 1969). Mature larvae of Paraleptophlebia westoni can be distinguished by the following features: thorax is not hairy (in contrast to P. volitans ); hypopharynx is slightly emarginated apically (Fig. 19) (in P. calcarica , P. lacustris and P. strandii have medioapical cleft); maxillary palp segments 3 slightly longer than segment 2, together 1.65 times longer than segment 1 (Fig. 18) (in P. debilis P. moerens P. submarginata, P. guttata and P. strigula segments 2 and 3 together are equal to segment 1); labial palp segment 2 is shorter than segment 3, and together nearly equal segment 1 (Fig. 19) (in P. falcula labial palp segments 2 is shorter than segment 3, and together are longer than segment 1); legs have no brown band (Fig. 22) (in contrast to P. debilis and P. jeanae ); row of denticles reaches middle or slightly more than the middle of the claw (Fig. 23) (in P. ruffoi and P. werneri row of denticles occupies more than half of claw); abdominal segment VIII and IX with posterolateral spines (in P. guttata and P. strigula lateral spines are present on segment 9 only). : Published as part of Tiunova, Tatiana M., 2017, A new species of Paraleptophlebia Lestage, 1917 (Ephemeroptera: Leptophlebiidae) and a re-description of adults for Paraleptophlebia westoni Imanishi, 1937 with the first description of the larva, from the Russian Far East, pp. 109-120 in Zootaxa 4337 (1) on pages 113-118, DOI: 10.11646/zootaxa.4337.1.5, http://zenodo.org/record/1014073 : {"references": ["Imanishi, K.
