A new Orthosia species, O. habeleri sp. nov., is described from Iran (Kerman, SE Zagros Mts), and compared with the allopatric, closely related species, O. manfredi Hreblay, 1994. The subgenus Orthosia and its three main lineages are characterised; the primary types of the taxa described by Staudinger and Hreblay & Plante are illustrated; the photographs of the male genitalia of the holotypes of O. manfredi Hreblay, 1994, O. ariuna Hreblay, 1991, O. faqiri Hreblay & Plante, 1994 and O. feda Hreblay & Plante, 1994, and the lectotype of O. incerta var. pallida Staudinger, 1888 are illustrated for the first time.
The genus Orthosia Ochsenheimer, 1816 is a large Holarctic-Oriental group of the tribe Orthosiini (Noctuidae, Hadeninae), comprising more than sixty species, and the majority of them occurring in eastern and south-eastern Asia. Five species of the genus Orthosia (s.l.) are currently known from Iran: O. cruda ([Denis & Schiffermüller], 1775), O. gracilis ([Denis & Schiffermüller], 1775), O. imitabilis Hreblay, 1993, O. incerta (Hufnagel, 1766) and O. sordescens Hreblay, 1993. The subgeneric taxa accepted in the most recent literature (
The tribe Orthosiini, and within it the genus Orthosia, is conspicuously heterogeneous in external and genital morphology throughout the Palaearctic and Oriental regions. The great majority of the genera and species of the tribe occur in the Himalayan region, more precisely, in the Himalayan-Sino-Pacific region, which includes the main chains of the Himalaya from Pakistan to northern Indochina and the eastern frontier of the Tibetan Plateau, together with the western and central Chinese mountainous regions, Taiwan and the southern parts of Japan and continental Pacific areas (see
The bulk of the taxa belonging to Orthosia were recently described (
In the first decade of the 21st century, two specimens of a curious species of Orthosiini were collected in the Kerman area of the southern Zaghros Mts and later examined independently by the authors. These specimens resemble externally mostly certain western Himalayan species of the noctuid genus Harutaeographa Yoshimoto, 1993, especially the dark examples of H. bidui Hreblay & Plante, 1996, H. rama Hreblay & Plante, 1996 and H. brahma Hreblay & Ronkay, 1998 (see Figs
Our study is based on the examination of a large set of material of the taxa belonging to the subgenus Orthosia, including the type-specimens of all but one species. The external and genitalic features of O. ronkayorum Volynkin & Titov, 2014 were evaluated from the text and illustrations of the original description. The material was set and dried in a conventional way. Genitalia preparations followed standard techniques for Noctuoidea, including the eversion of the vesica.
Representative material of the taxa of the subgenus Orthosia was studied and photographed. The type material was examined in the Hungarian Natural History Museum (
The genitalia of the three groups in the subgenus Orthosia are rather well illustrated, see for instance the works of

The first really detailed description of the major lineages of Orthosia s. l. was published in Italian by
The subgenus Orthosia comprises medium-sized or rather large species (wingspan 30–45 mm), with elongated, relatively narrow, apically pointed forewings; forewing pattern can be variously expressed, often blurred, or rather sharply marked, with distinct crosslines and orbicular and reniform stigmata; colouration very variable; the individual variation is remarkable in all known species. The most typical external morphological feature of the subgenus is the biserrate male antenna (with long, fasciculate cilia), its pectination is shorter than in the other major groups of Orthosia. It is worth to mention that the female antenna is not filiform as in most other groups of Orthosia s.l. but, minutely or shortly, biserrate, with long sparse fasciculate cilia.
The male genitalia of the subgenus Orthosia are characterised by the following group features: 1) male genital capsule strongly sclerotized, symmetrical; 2) uncus usually scaphoidal; 3) juxta strong, narrow and long, quadrangular; 4) vinculum strong, very long, V-shaped; 5) valva elongate with most often characteristically S-shaped costal margin; 6) cucullus small or medium-sized, acutely triangular (except in O. habeleri and O. perfusca), most often with strong, cuneate pollex (reduced only in O. manfredi, O. habeleri and O. perfusca; 7) corona absent; 8) sacculus long, distal end heavily sclerotized; 9) clavus usually large, lobate, rounded; 10) ampulla strong, falcate or arched thorn-like; 11) harpe with short, digitiform or pyriform (erected) process; 12) aedeagus long, cylindrical, carina with long, heavily sclerotized, acute ventral (or subventral) thorn and short, straight ventro-lateral bar; 13) vesica broadly tubular, membranous, recurved ventro-laterally, with subconical medial diverticulum.
The diagnostic features of the female genitalia are as follows: 1) ovipositor relatively long, conical, apophyses posteriores long, slender; 2) antrum narrowly lyriform or calyculate, heavily sclerotized, often with serrate-dentate lateral crests; 3) ductus bursae long, tubular, variably thick, most often dilated distally; 4) appendix bursae membranous, helicoid; 5) corpus bursae ellipsoidal-ovoid, with four long signum-stripes; 6) last sternite with narrow, long, sclerotized bars.
The subgenus Orthosia is a rather compact species group consisting of three main lineages, the O. incerta-, the O. picata-, and the O. evanida-lineages. This subgenus is still a challenging complex from a taxonomic point of view, containing externally often confusingly similar species, while the genitalia of both sexes display clearly recognisable distinctive features. The genitalia of both sexes do not show distinctive variation within a species, despite the great individual variation in the external features; even the Trans-Palaearctic O. (O.) incerta has actually only one recognised subspecies, the Japanese ssp. incognita.
The members of the O. incerta-lineage differ externally from those of the O. picata-lineage mainly in their larger size, sometimes also by their the more blurred forewing pattern while the genitalia show differences in the general features, e.g. the shape of the uncus, the configuration of the distal part of the valva, the length of the pollex and the thorn of the carina (males), the shape of the sclerotization of the antrum and the shape and thickness of ductus bursae (females). The members of the O. evanida-lineage are externally rather similar due to their rather large size, broad forewings with distinct antemedial, postmedial and subterminal lines and well-marked, large orbicular and reniform stigmata. This lineage appears more heterogeneous, however, by the configuration of their male genitalia (see
Holotype . Male, Iran, Kerman, Kuh-e-Hessar/Abshar, 2820 m, 29°33’N, 57°18’E, 28.iv.2006, leg. B. Plössl & G. Tarmann; slide No. N1595 (coll. TLMF, Hall in Tyrol).
Paratype . Male, Iran, Kerman, Jiroft, Mardehak, 2273 m, v.2009, leg. M. Shoghali; slide No. AS532 (coll. Shahid Bahonar University, Kerman).
The new species belongs to the incerta-lineage, its closest known relative is the Moroccan O. manfredi, due to the progressive series of similar morphological reductions in the male genitalia (reduction of the pollex, and the shortened carinal thorn or the rather straight aedeagus). On the other hand, there are a number of easily recognisable specific external and male genital features which distinguish the three closely related species, O. habeleri, O. manfredi and O. incerta.

The species is known from the regions of high elevation of the southern Zaghros Mts (the two specimens were collected above 2200 m elevation). The biology is poorly known, but the flight period is in late spring (April–May), similar to several other species of the genus.
The new species is dedicated to Heinz Habeler (Graz, Austria), who was the mentor providing enthusiastic help and motivation to the first author.
