Aschistophleps longipoda — Gorbunov & Arita 2002 : [193], 195; Pühringer & Kallies 2004: 14 ; Skowron Volponi & Volponi 2017a: 5 ; Skowron Volponi & Volponi 2017b: 135 , 139; Skowron Volponi & Volponi 2018: 281 ; Kallies & Štolc 2018: 597 , 599; Skowron Volponi 2020: 6 ; Pühringer & Kallies 2020 . This species was described in detail from a series of 11 males collected using synthetic unspecific sex attractants ( Arita & Gorbunov 2000 ). Like specimens of the type series, males collected in Laos have practically no differences in the colouration of various parts of the body. One male ( Figs 9–10 ) turned out to be very small, which somewhat shifted the variability of individual size downward: alar expanse 15.5–24.2 mm ; body length 7.5–12.4 mm ; forewing 7.2–11.0 mm; antenna 4.4–7.6 mm .

Unfortunately, the species of the genus have almost identical male genitalia. Very slight differences can be found in the valva and saccus shapes. In addition, there are several differences in the length and thickness of the aedeagus (cp. Figs 27–32 ). Bionomics. The host plant is unknown. Males in Laos was collected during April. They were mud-puddling. FIGURES 1–6. Variability of males Aschistophleps longipoda Arita & O. Gorbunov, 2000 . Laos, Khammouang Prov., Ban Khounkham (Na Hin), 18˚13΄N, 104˚31΄E, 200 m, O.

In Laos it inhabits a primary, monsoon, semi-deciduous, lowland, tropical forest with Dipterocarpus alatus Roxb. ex G.Don , Hopea odorata Roxb. , H. ferrea Laness. (Dipterocarpaceae) , Lagerstroemia cochinchinensis Pierre ex Laness. (Lythraceae) , Afzelia xylocarpa (Kurz) Craib (Fabaceae) and Alstonia scholaris (L.) R . Br. ( Apocynaceae ) as the most dominant species ( Gorbunov, 2015b , 2021b ). Distribution. This species is known from the type locality in North Vietnam and in Laos . This is the first record for the country.
