Type locality. N Vietnam, Hòa Bình Province.
Type material. Holotype: “ 15.01.1976 Bьeтнaм, Xao бинь, Л. H. Meдвeдeв, УФ cвeт, 36” [15.01.1976 Vietnam, Hòa Bình, L.N. Medvedev, UV light, 36—in Russian], ♂ (ZISP). Paratype: “ 15.01.1976 Bьeтнaм, Xao бинь, Л. H. Meдвeдeв, УФ cвeт, 33” [18.01.1976 Vietnam, Hòa Bình, L.N. Medvedev, UV light, 33—in Russian], ♀ (IBIW).
Description. Holotype, ♂. Total length 3.2 mm (from apex of labrum to apex of elytra). Body (Fig. 1) moderately elongated, dorsoventrally compressed. Head light brown, with dense whitish pubescence and longer scattered setae; mandibles average, not hypertrophied, with acute apex; eyes well developed, antennae with 10 antennomeres, apical 7 antennomeres forming club; clypeus without pair of anterior horns, with dense and short setae, labrum dark brown. Pronotum light brown, with disc darker, evenly wide or slightly narrower than elytra at base, rectangular, densely punctured, bordered posteriorly, laterally with dense whitish pubescence and longer setae. Elytra with pale brown spots (Fig. 1), densely and uniformely punctate, with dense whitish pubescence; elytral longitudinal ridges only slightly indicated. Setae of elytra short, sparse, semierect. Legs light brown, densely pubescent; tibiae with numerous spines and long setae. Abdomen light brown, stridulatory arch marked; postmetacoxal line present. Aedeagus (0.7 mm long) and spiculum gastrale (V-shaped) as in Fig. 2.
Paratype, ♀. Total length 3.3 mm (from apex of labrum to apex of elytra). Externally similar to male, but mandible, head and pronotum smaller. Head and pronotum brown.
Variability. Body size 3.2–3.3 mm. Males and females are very difficult to separate without examination of the genitalia. Elytral markings slightly differ in two studied specimens (spots of holotype specimen is more contrasting).
Differential diagnosis. Based on the shape of the male genitalia, and shape of the elytral pattern, Augyles letovi sp. nov. is probably most related to the south-east Asian species Augyles rejseki Skalický, 1999 (described from Thailand) and Augyles hiekei (Mascagni, 1995) (described from Vietnam). A. letovi differs from A. rejseki by the tegmen, having lateral margin evenly curved (not dentate) and possessing paired sclerotized elements in basal part (Fig. 2). A. letovi differs from A. hiekei also by the structure of tegmen presence possessing paired sclerotized elements in basal part.
Ecology. All specimens were collected at light.
Distribution. So far known only from the type locality.
Etymology. Dedicated to Igor Fedorovich “Yegor” Letov, Russian poet, musician, singer, songwriter, audio engineer and conceptual art painter, best known as the founder and leader of the post-punk/psychedelic rock band Grazhdanskaya Oborona (Civil Defense).
