A new species of the genus Perigrapha, P. yasawii sp. n. is described from Syrdarya river valley, South Kazakhstan. The adults and male genitalia of the new and related species are illustrated.

The Holarctic genus Euchalcia Hübner, [1821] belongs to the tribe Plusiini of the subfamily Plusiinae. The genus is one of the largest in the Plusiinae, comprising about 54 described species. The systematics of Eurasian and North African members of the genus was recently revised (Ronkay et al. 2008). In June 2013, in the course of faunistic studies on Noctuidae of the Tarbagatai Mts. (East Kazakhstan), a long series of an undescribed species of the genus was collected. Two additional specimens from the Dzhungarsky Alatau Mts. (South-East Kazakhstan) were found in the collection of the Siberian Zoological Museum (Novosibirsk). The species is described herein as new. It belongs to the E. inconspicua group within the E. inconspicua species-complex (Ronkay et al. 2008). The E. inconspicua group comprises two described species only: E. inconspicua (Graeser, 1892) and E. anthea L. Ronkay, G. RonkayBehounek, 2008. The new species is the northernmost member of the group. Institutional acronyms are as follows: AVB-coll. A.V. Volynkin, Barnaul, Russia; MČK-coll. M.

Noctuidae is one of the most species-rich families of Lepidoptera (Nieukerken et al. 2011). The Palaearctic noctuid genus Dasypolia Guenee includes more than a hundred species some of which are still undescribed. The genus is distributed predominantly in the mountain massifs of Asia, reaching the highest species diversity in the Tibetan and Himalayan regions. Many species of Dasypolia have been described during last three decades (Hacker & Peks 1990, 1992, 1996; Ronkay & Varga 1990; Ronkay et al. 1991; Ronkay & Plante 1992; Ronkay & Zilli 1993; Gyulai & Ronkay 1995; Hreblay & Ronkay 1995, 1999; Ronkay et al. 1995; Hacker & Ronkay 1996; Hreblay & Ronkay 1998; Hreblay et al. 1998; Ronkay et al. 1998; Ivinskis & Saldaitis 2010; Benedek et al. 2011; Volynkin 2012; Benedek et al. 2014; Ronkay et al. 2014; Benedek & Saldaitis 2014). The genus is now subdivided into twelve subgenera, six of which have recently been described by Benedek et al. (2011) and Benedek & Saldaitis (2014). One subgenus, Tschetwerikovia Bundel, 1966 has been synonymised with the nominate subgenus by Ronkay et al. (2014).

Orthosia Ochsenheimer, 1816 is a Holarctic-Oriental noctuid genus comprising more than 60 described species, with most distributed in the eastern and southeastern Palaearctic and Oriental regions. Many species have recently been described from Asia (Hreblay 1991, 1993, 1994; Yoshimoto 1993; Hreblay & Plante 1994; Hreblay & Ronkay 1998, 1999; Ronkay et al. 2010, Saldaitis et al. 2011, etc.). The O. incerta species-group includes 10 described species (see Ronkay et al. 2001), and during the course of faunistic studies on the Noctuidae of North-East Kazakhstan, a new member of this species-group was found; it is described herein as new.
