The nominative subspecies, Pogonarthron tschitscherini tschitscherini, has been described as Polyarthron Tschitscherini from Kyrgyzstan (Osh environs)
by Andrej P. Semenov Tian-Shanskij in 1889 [▽]. Pogonarthron tschitscherini pallidus has been described from Kyrgyzstan and Uzbekistan by Mikhail Danilevsky
and Andrej Shapovalov in 2017 [❖]. The subspecies occurs in foothills at the south part of Fergana valley (Kyrgyzstan and Uzbekistan) and in north foothills
of Alay Ridge near Nayman water reserve and Kyzyl-Kiya (Osh and Batken regions, Kyrgyzstan). P. tschitscherini inhabits savanoid steppe areas in foothills,
its habitats could be totally treeless, but also are often covered by Pistacia bushes. Larval development in the soil, larvae probably feed on
roots of available plants. Each subspecies is characterized with certain hours of male activity. Males of the nominative subspecies are mostly active at the end of the daylight
in about 18:00-19:00, several specimens were observed later after sunset in the twilight. Males of P. t. pallidus are active in the total darkness. The period of female
activity coincides with male activity. Females spend almost whole life inside in their holes in soil. Female ready for copulation leaves the soil through
this opening and attracts males by rotate her ovipositor (sexual pheromone emission). Female hides herself inside her hole immediately after copulation. Males are able
to penetrate inside female holes and copulate there, so many females are not obliged to leave the soil. [❖].
