Pachydissus sartus, a widely distributed Central Asian species, has been described from Samarkand (Uzbekistan) as Pachydissus sartus by Simon Martynovitsch Solsky in 1871 [✩].
This spectacular longhorn beetle is one of the most important insect pests of broadleaf trees in Central Asia [✮][❖]. It can frequently be found in avenues or parks in highly
urbanised areas. Adults usually leave their pupation cells in April or the beginning of May and are crepuscular and nocturnal. During the daytime, they hide under
the bark, in larval galleries, and in other refuges. They leave the hideout at dusk, males appearing first, and move about until morning on the surface of
the particular tree on which they developed. T. sartus does not fly much and maturation feeding has not been observed.
In the detailed revision of the closely related Austrasian Austrasian genera Trirachys Hope, 1843, Aeolesthes Gahan, 1890 and Pseudaeolesthes Plavilstshikov, 1931,
published by Francesco Vitali et al. in 2017 [❖], was the species included in the genus Trirachys Hope, 1841.
