New data on the clearwing moth fauna of the Altai Mountains, Russia, with the description of two new species (Lepidoptera, Sesiidae)

Abstract

The clearwing moth fauna of the Altai Mountains, Russia is reviewed. Two new species Synanthedon altaica sp. nov. and Bembecia aktashica sp. nov. are described and illustrated. Synanthedon polaris (Staudinger, 1877) is recorded as new for the region. New information on the bionomics and distribution of Dipchasphecia altaica O. Gorbunov, 1991 is provided.

To the distribution of the genus Negotinthia O. Gorbunov, 2001 (Lepidoptera: Sesiidae) in the Crimea

“…This work continues a series of authors' investigations of the Lepidoptera (mainly Sesiidae and Zygaenidae) of the world fauna (see e.g. Efetov 1997aEfetov , 1997bEfetov , 1998Efetov , 1999Efetov , 2001Efetov , 2006Efetov , 2010Efetov et al 2004;, 2014, 2015a-b, 2016, 2017, 2018a-c, 2019a, Gorbunov 2023b-e, 2024aGorbunov & Gurko 2017;.…”

A peculiar new species of gall-inducing, clearwing moth (Lepidoptera, Sesiidae) associated with Cayaponia in the Atlantic Forest

“…These diurnal micromoths are well known by their morphological and behavioral modifications that have been associated with Batesian mimicry, particularly regarding bees and wasps (Duckworth and Eichlin 1974; Skowron et al 2015). In the last decades, many of their species have been found by attracting the adults with the use of synthetic sex pheromones (Duckworth and Eichlin 1977b; Brown and Mizell 1993; Špatenka et al 1999; Arita and Gorbunov 2000; Arita et al 2009; Skowron et al 2015; Gorbunov 2018).…”

Two new species of the genus Bembecia Hübner, 1819 [“1816”] (Lepidoptera: Sesiidae) from Western Mongolia

“…; cp. Figs 3-4 in this article with figs 21-28 inGorbunov, 2018) and abdomen (dorsally black with dark greenish sheen; tergites 2 and 4 each with few yellow scales distally; tergites 6 and 7 each with a narrow yellow to yellow-orange stripe distally; ventrally dark brown to black with blue-greenish sheen; sternites 4 and 7 each with narrow yellow stripe distally; anal tuft dorsally black with dark greenish-blue sheen, ventrally yellow-orange B. aktashica, vs. black with dark violet shine; tergite 2 with a row of yellow scales distally; tergites 4, 6 and 7 each with broad yellow stripe distally; ventrally sternite 4 yellow; sternites 5-7 each with broad yellow stripe distally; anal tuft dorsally black with dark violet shine, admixture of yellow scales medially and yellow ventrally in B. yakovlevi sp.n. ; cp.…”

“…; cp. Figs 3-4 in this article with figs 21-28 inGorbunov, 2018). In addition, these two species are well distinguished from each other by the structure of the transparent areas of the forewing (transparent areas poorly-developed, posterior transparent area nearly undeveloped, anterior transparent area rather small, densely covered with translucent scales with light golden-greenish hue; external transparent area relatively small, covered with translucent scales with light golden-greenish hue, divided into four cells between veins R 4+5 and CuA 1 , level to vein M 2 about as broad as discal spot and about twice broader than apical area B. aktashica, vs. transparent areas well-developed, densely covered with translucent scales with light golden hue; posterior transparent area short but reaching level of discal spot of hindwing; external transparent area large, rounded, divided into four cells between veins R 5 and CuA 1 , level to vein M 2 about three times as broad as discal spot and about 4.3 times as broad as apical area in B. yakovlevi sp.n.…”

“…of the genus were described from the Arabian Peninsula, namely Pyropteron balkis Le Cerf, 1937 (type locality: [Yemen] "Arabia, San'a Waila, …") (transferred to the genus Bembecia by Heppner, Duckworth, 1981: 39) and Bembecia balkis atrocaudata Wiltshire, 1986 (type locality: "Saudi Arabia, Taif, …") [Gorbunov et al, 2017;Gorbunov, Efetov, 2018;Gorbunov, 2018Gorbunov, , 2019Gorbunov, , 2023. Unfortunately, the genitalia of these two taxa have not yet been studied, and it is rather difficult to establish a generic affiliation only by appearance.…”
