Name
Palerasnitsynus Wichard & Ross & Ross, 2011 gen. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type species
Palerasnitsynus ohlhoffi sp. n.
Etymology
The new genus is named after Prof. Dr. Alexandr P. Rasnitsyn on the occasion of his 75th birthday, in recognition of his extensive work on Palaeoentomology.
Diagnosis
Genus Palerasnitsynus gen. n. differs from all extant genera (Paduniella Ulmer, 1913, Psychomyia Latreille, 1829, Psychomyiella Ulmer, 1908, Lype Mclachlan, 1878, Padangpsyche Malicky, 1993, Tinodes Curtis, 1834, Trawaspsyche Malicky, 2004, Eoneureclipsis Kimmins, 1955, and Zelandoptila Tillyard, 1924) and the extinct genus (Arkharia Sukatsheva, 1982) by the absence of apical fork III in the forewing.
Description
Head: Ocelli absent. Antennae filiform, almost as long as forewings; each scapus only slightly longer than each pedicel and individual flagellomeres; flagellomeres cylindrical. Maxillary palps 5-segmented in both sexes, terminal 5th segment flexible, annulated, and at least twice as long as each of the other segments. Labial palps 3-segmented with flexible, annulated, long terminal segments.
Thorax: Mesoscutum with one pair of setal warts. Legs with tibial spurs 2/4/4. Wings elongate, rounded at apex, hind wings narrower than forewings. Forewing subcosta (Sc) simple, terminating into costa (C) at about three quarters the length of wing. Radius R1 simple; R2+3 unforked, R4+5 forking into R4 and R5 (fork II) close to potential crossvein r; discoidal cell (Dc) short. Media M1+2 unforked, M3+4 forking into M3 and M4 (fork IV); crossvein m indistinct; median cell (Mc) apparently open. Cubitus Cu1 bifurcated into Cu1a and Cu1b (fork V); Cu2 simple; crossvein m-cu apparently present, closing thyridial cell (Tc). Forewings with forks II, IV, and V.
