Calosoma (Callisthenes) usgentense Solsky, 1874

C. usgentense, as C. regelianum and C. mirificum, has elongated and convex elytra, with a smooth surface where the striae are indicated by series of points; the suture is more or less depressed; the colour of the upper body is black or dark.
C. usgentense is further distinguished from other species in the group, because of the lateral margin of pronotum narrow, almost smooth or very slightly wrinkled. Moreover the lateral margin of pronotum is clearly separated by a little protuberance, from the dimples near the hind angles. The elytral margin is smooth.

Callisthenes usgentensis karaalmensis Obydov, 1999: 135 (type: Kara-Alma; Zoological Museum of Moscow University)

Length 21-28 mm. C. usgentense usgentense is characterized by a relatively elongated body shape and by a larger size.
Obydov (1999: 135), has distinguished, at subspecies level, Callisthenes usgentensis karaalmensis, from the north of the Fergana valley, which is characterized by head and disk of pronotum more densely punctate, and more elongated elytra, with almost parallell sides.
The various populations of C. usgentense usgentense are widespread in south-western Kyrgyzstan and in eastern Uzbekistan.


Examined specimens and literature’s data
Kyrgyzstan: Uzgen (= Usgent) (type); Osh (SB); Ozhalal-Abad (SB); Kara-Alma, Tash-Kumyr (sub karaalmensis Obidov, 2002: 64); Suusamyr Tau, Dongus Tau (Breuning, 1928b: 72)
Uzbekistan: Kokand, Toguz Torau (Breuning, 1928b: 72), Andishan (= Andizhan) (Obidov, 2002: 62); Nanai (sub karaalmensis Obidov, 2002: 64), Margilan (EM), Namangan (sub rugiceps Heyden & Kraatz,1885: 227).

Notes: Brachypterous. It lives mostly in foothills, plains and low hills but in Ferghan Ridge it has been found in forested areas, around 1500-2100 m. altitude. Adults were collected from March to June for the populations of the plains and in June and July for those of higher altitudes (Obydov, 2002).

Calosoma (Callisthenes) usgentense mandli Bruschi, 2013

Calosoma (Callisthenes) alaiense Mandl, 1967: 48 (nec Lapouge, 1930) (type: Tuja Mujun, Kitschik Alaisker-Gebirge; Naturhistorischen Museum Basel)
Calosoma (Callisthenes) usgentense mandli Bruschi, 2013: 245 (nomen novum pro alaiense Mandl, 1967)

Length 18-22 mm. Mandl (1967: 48) described Calosoma (Callisthenes) alaiense from Tuja-Mujun, that is in the steppe in the southern part of the Fergana Valley in what can be considered the extreme northern slopes of the Alai range. He compares his new form with C. usgentense from which it differs mostly because of the rounded and short shape and because of less prominent and more rounded rear angles of pronotum.
The examined specimens from the type locality and from other surrounding places in the south-western part of the Fergana Valley, constantly present the characteristics given in the original description. Particularly, all of them are on average smaller and with shorter and more rounded elytra. The legs are of normal length, but the articles of the posterior tarsi in both sexes are considerably shorter and thicker of what is found in other populations.
These differences justify to consider it as a valid subspecies of C. usgentense. However the name Calosoma (Callisthenes) alaiense should be replaced, as it is preoccupied by Caminara (Campalita) auropunctata alaiensis Lapouge, 1930, and, to replace it, the name mandli has been proposed (Bruschi, 2013: 245) in honor of Karl Mandl (1891-1989), the famous Austrian entomologist that first described the taxon.

Examined specimens and literature’s data
Uzbekistan: Tyuya-Muyun (holotype of C. alaiense NMB, SB); Karkidon Lake (SB)

Notes: Brachypterous. It lives mostly in foothills and plains. All the examined specimens were collected in April.
