Olethreutes pivanica Dubatolov, Bogunova & Nedoshivina, sp. n. (Figs. 5���6) Type material: Holotype: ♂, RUSSIA, Khabarovsk Province, near Komsomolsk-na-Amure, Pivan, 50 �� 34 ��� N 137 �� 03��� E, 16.vi. 2008, leg. V. V. Dubatolov. Deposited in ISEA. Paratype (allotype): female, the same locality, 14.vi 2008, leg. V. V. Dubatolov. Description. Forewing length 9 mm. Head: Dark brown; labial palpi relatively small, slightly broadened distally, covered by dark brown scales. Antennae brown, ca. one-half forewing length. Thorax: Dark brown. Forewing with costal margin slightly convex, apex rounded, termen slightly oblique, tornus rounded; upperside ground color brownish-black; pattern typical of members of genus, consisting of transversal dark brownish fasciae with narrow, lighter, dove grayish striae between them; median stria not contrasting, with sparse dark scales, extending from basal one-third of costa towards one-half of dorsal margin, outer margin of dark median fascia slightly convex, jagged, with small angle in central cell; postmedian transversal stria fused dorsally, enclosing darker pretornal patch; submarginal stria dark and indistinct; dark external field triangularly narrowed towards tornus; light pattern brighter around discal vein. Forewing cilia brownish-grey. Hind wing ovoid with slightly extended apex, dark brown with slightly lighter base; costal margin with elongate basal lobe about 1 / 3 of costal length, its fore margin with elongate special androconial scales (Fig. 12). Cilia lighter than hindwing. Abdomen: Dark gray. Male genitalia (Fig. 10) with uncus bifurcate apically, covered with long hairs. Socii separate, partly fused with tegumen, forming broad ovoid processes, covered with long hairs. Gnathos membranous. Valva long, with broad basal part; cucullus roughly widened apically, forming round club covered by long chaetae; cucullus apex more than four times as broad as valva neck; valva neck long, narrow, without chaetae; sacculus with narrowly triangular apical process, broader towards costa, narrower ventrally, forming rounded ventral lobe, densely covered with strong chaetae; field of chaetae expanded at costa forming a row at cucullus base, ending in two strong chaetae; sacculus with a cluster of chaetae near ventral lobe of triangular process, ventral edge of sacculus covered with row of hairs; anterior group of sparse, weaker chaetae located at distal edge of basal cavity. Aedeagus slightly curved, dorsally membranous; sclerotized ventral part of aedeagus forming a narrow apical process, curved clockwise with a strong spine on dorsum. Female genitalia (Fig. 11) with papillae anales narrow, elongate, slightly broadened apically. Sternite VII horseshoe-like, forming two broad bands laterally from ostium. Ostium surrounded by broad semicircular sclerite extended caudally. Vaginal sinus forming narrow goblet-like sclerite, slightly hollowed proximally. Ductus burase moderate in length. Corpus bursa ovoid, without signum. Diagnosis. Olethreutes pivanica is not easily distinguished from the related Palearctic species by wing pattern alone, but it is noticeably darker. The male genitalia of O. pivanica are similar to those of O. magadana (Falkovitsh 1965) from the Kolyma region in the North-East Asia and O. kamtshadala (Falkovitsh 1966) from Kamchatka. All these species have a strong process of the sacculus that is covered by dense strong chaetae; the basal part of valva is broad, and the cucullus is club shaped. Although similar, the shape of the sacculus process is different: ovoid and broadly rounded apically in O. kamtshadala, narrowly triangular in O. pivanica, and broadly triangular in O. magadana. The ratio of the length to width of this process is about 2: 1 in O. pivanica and 1: 1 in O. magadana. The row of chaetae on the costal edge of the process base is long in O. pivanica (nearly equal to the length of the process) and very short in O. magadana. The ratio of the length to width of the valva neck is 3: 1 in O. pivanica and 4: 1 in O. magadana. In addition, the club shape of the cucullus is more or less round in O. pivanica and ovoid in O. magadana. The North American species O. bowmanana (McDunnough 1923) is less similar to the new species than are the two East Asian ones. The saccular process of O. bowmanana is very broad, nearly rectangular, and expands immediately from the basal cavity, whereas in all Asian species it is located conspicuously more distal. The valval neck in O. bowmanana is short and very broad, only slightly narrower than the cucullus apex. Biology. Olethreutes pivanica was collected at the lower part of a petrophytous sunny slope of a terrace of the Amur River bank. Moths were flying over the small boulders covered with sparse vegetation. The species probably occurs in the middle part of the petrophytous slope, but the slope is too steep for collecting. The species flew with the more common Cnephasia ussurica Filipjev 1962, and these were the only tortricoid species observed at this slope. Neither was found in other places of the Region (Syachina 2008), and they are probably restricted to this biotope. Another characteristic species at this site was the Holarctic Clossiana tritonia (Boeber 1812) [Nymphalidae], represented by the topotype population of C. t. amphilochus (M��n��tri��s 1859). Distribution. Olethreutes pivanica is probably restricted to the Lower Amur basin and the mountains of the Region. Etymology. The new species is named after the type locality place, Pivan. Remarks. The new species is most similar to O. magadana, which was reported to occur in Chukotka, Magadan Province, Koryakia, Chita Province and Taimyr (Kuznetzov 2001). We found a few specimens labeled as O. magadana that were identified incorrectly by V. I. Kuznetzov in the collection of the Zoological Institute, St. Petersburg. After dissection, specimens from Chukotka were identified as O. exaridana (Kuznetzov 1991); a female from Kolyma was not identified, but it is not similar to the O. magadana-kamtshadala species group based on its genitalia. Another female from Taimyr has the genitalia similar to the new species and belongs to an uncertain species of the same complex. So, O. magadana Flkv. is actually known only from the Kolyma basin. All other data about distribution of O. magadana Flkv. in Chukotka and Kolyma were probably based on the incorrect identification. Additional specimens from Chukotka identified by Prof. V. I. Kuznetzov as O. kamtshadala Flkv. belong to Cymolomia taigana Falkovitsh, 1966. Thus, occurrence of O. kamtshadala Flkv. in Chukotka remains also questionable., Published as part of Dubatolov, Vladimir V., Bogunova, Anna A. & Nedoshivina, Svetlana V., 2014, Review of the Olethreutes bowmanana-magadana species group, with the description of a new species from the Amur River, Russia (Lepidoptera, Tortricidae), pp. 375-382 in Zootaxa 3779 (3) on pages 380-381, DOI: 10.11646/zootaxa.3779.3.5, http://zenodo.org/record/226315, {"references":["Falkovitsh, M.

Olethreutes bowmanana (McDunnough 1923) (Fig. 1) Argyroploce bowmanana McDunnough, 1923. Canadian Entomologist 55: 165���166 (Type locality: Canada, Alberta, Nordegg [Holotype: CNCO]). Material examined. 1 ♂ (holotype), No. 607, [Canada], Alta [Alberta], Nordegg, 23.vii. 1922, K. Bowmann leg. [coll. CNCO]. Remarks. This species was described by McDunnough (1923) on the basis of the wing pattern and assigned to Argyroploce H��bner, [1825]. Heinrich (1926) treated Argyroploce as a junior synonym of Olethreutes H��bner, [1822], and provided only a short diagnosis, without a detailed illustration of the male genitalia. Hannemann (1961) rejected Heinrich���s (1926) opinion and treated Argyroploce as a separate genus. Falkovitsh (1965, 1966) followed Hannemann (1961) and described two species, Argyroploce magadana and A. kamtshadala, both from Russia. In his monograph on the Tortricidae of the Russian Far East, Kuznetzov (2001) also treated Argyroploce as a separate genus and noted that the Russian tundra species A. magadana is replaced in North America by the related A. bowmanana. Based on a study of the type material of O. bowmanana, we conclude that this species indeed bears a strong similarity with, and is probably related to O. magadana and O. kamtshadala. A redescription of O. bowmanana is given below with a special emphasis on the characters shared with the Palaearctic species. Description. Forewing length 8 mm. Head: Vertex and palpi with a mixture of blackish and grayish scales. Antennae dark gray, about half a long as forewing. Thorax: Concolorous with head. Forewing elongate, with costa nearly straight, termen oblique and straight, dorsal angle rounded; upperside ground color grayish brown, with distinct pattern; basal, median and postmedian fasciae well defined, with narrow dark striae between them; subbasal fascia narrow, curved in median cell, broader dorsally, with outer margin distinct; median fascia narrow; outer margin distinct, fissured, with a process beyond whitish discal spot; postmedian fascia divided by costal strigula; preterminal fascia narrow; apical spot small, round, and blackish; costal strigulae whitish gray. Cilia brownish gray, and checkered with darker spots; marginal line well defined. Hindwing elongate-ovoid, with narrowly rounded apex; grayish brown. Cilia concolorous with wing. Anal roll well developed. Abdomen: Dark gray. Male genitalia (Fig. 9) with uncus bifid, covered with long hairs. Socii digitate, laterally fused with tegumen. Valva elongate; cucullus rounded, spatulate, slightly wider than neck of valva; neck shorter than cucullus, ratio of its length to width 1.5: 1; basal part of valva broad; lobular process at distal part of sacculus covered with strong spines, cluster of spines extending basally and costally to nearly basal cavity; sacculus at basal side of lobular process with wide setose spine cluster; ventral edge of sacculus covered with row of setae. Aedeagus slightly curved downward, dorsally membranous; sclerotized ventral part projecting distally to form a narrow apical foldable process with strong spine on right side apically. Female genitalia unknown. Diagnosis. Olethreutes bowmanana is most similar to O. kamtshadala but can be distinguished by the following characters: valvae neck wider, slightly narrower than cucullus, whereas in O. kamtshadala the neck is less than half as wide as the cucullus; the lobular process of the sacculus is wide and flat, not raise above the other parts of sacculus; the setose spine cluster on the ventral margin of the sacculus is wider than that of O. kamtshadala and consists of stronger spines; and the aedeagus is longer, approximately 6 times its width, and nearly the same width throughout, whereas in O. kamtshadala the aedeagus is about 3 times as long as its maximum width and the tip about half as wide as the base.

Olethreutes H��bner [1822] Systematisch-alphabetisches Verzeichniss aller bisher bey den F��rbildungen zur Sammlung europ��ischer Schmetterlinge: 72. Type species: Phalaena Tortrix arcuana Linnaeus, 1761 = [Phalaena] arcuella Clerck, 1759 by subsequent designation. Olethreutes is a large Holarctic genus with 133 described species currently assigned to it (Gilligan et al. 2012). Species included in the genus exhibit a wide range of genital morphology wing patterns, and male secondary structures, making the genus extremely heterogeneous and probably polyphyletic. However, many species within Olethreutes show remarkable similarities to presumably closely related species, and many of these could be combined into natural groups. The Olethreutes bowmanana-magadana species group, proposed here, shows clear differences from other Olethreutes and is considered a natural group supported by following characters: brown to dark gray wing colour with lighter grayish striae and blackish spots; uncus narrow, bifid distally; sacculus with a distal internal lobe covered by strong spines and a spine cluster proximally on the ventral side; cucullus with a slender neck and apical widening; and aedeagus with foldable apical spine. The assignment of the species under consideration to the genus Olethreutes is generally accepted (Brown et al. 2005), but their relationships to other Olethreutes species remain uncertain., Published as part of Dubatolov, Vladimir V., Bogunova, Anna A. & Nedoshivina, Svetlana V., 2014, Review of the Olethreutes bowmanana-magadana species group, with the description of a new species from the Amur River, Russia (Lepidoptera, Tortricidae), pp. 375-382 in Zootaxa 3779 (3) on page 376, DOI: 10.11646/zootaxa.3779.3.5, http://zenodo.org/record/226315, {"references":["Hubner, J.

We define and review the Olethreutes bowmanana-magadana species group comprised of Olethreutes bowmanana (McDunnough), O. magadana (Falkovitsh), O. kamtshadala (Falkovitsh), and O. pivanica, sp. n., the last from petrophytous sunny slopes in the Amur River. The new species differs from other species of the group by a narrow, triangular-shaped apical process from the sacculus; a round, wide, apical bulb from the cucullus; and a longer, narrow neck of the valva.
