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 (

holotype
, male (Vietnam, Hòa Bình). Scale bar—1.0 mm. 2—A) aedeagus, B) spiculum gastrale. Scale bar—0.5 mm.
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).
