Stenocorus validicornis, a species occuring in Kyrgyzstan and Uzbekistan, has been firstly mentioned as Toxotus validicornis by Maurice Pic in 1900 [▽] and eventually described in detail by the same author in 1906 [✧]. Information on the larval biology of the species/subspecies are insufficient, but the mass collection of beetles in mountain meadows in the absence of trees and shrubs suggests a connection between the larvae and the roots of herbaceous plants [❖].

Stenocorus (Toxotochorus) validicornis mediocris, a subspecies known from North-East Uzbekistan and North-West Kyrgyzstan, has been described by Mikhail Danilevsky in 2012 [✩]. Adults, active from June to July, are diurnal and anthophilous.

Body length:♂♂ 13 - 25 mm / ♀♀ 19.5 - 30 mm
Life cycle:unknown
Adults in:June - July
Host plant:probably in roots of herbaceous plants
Distribution:Kyrgyzstan, Uzbekistan

The depicted mounted beetles were collected in Kyrgyzstan.
