Abstract. The genus Armenohelops Nabozhenko, 2002 (Tenebrionidae: Helopini: Cylindrinotina) with

9 species from Anatolia, Armenia and North Western Iran is revised. Two new species are described (both from Turkey): A. parvocularis sp. n., A. fouquei sp. n. New synonyms are established: Armenohelops bosphoranus (Allard, 1876) = Stenomax fundator Reitter, 1908, syn. n.; Armenohelops amasiae (Seidlitz, 1896) = Cylindronotus (Odocnemis) strangulatus Reitter, 1922, syn. n. New combinations are established: Armenohelops scutellatus (Reitter, 1902), comb. n. (from Odocnemis Allard, 1876), Armenohelops bosphoranus (Allard, 1876), comb. n. (from Odocnemis), Armenohelops amasiae (Seidlitz, 1896), comb. n. (from Odocnemis). Lectotypes of Stenomax scutellatus Reitter, 1902, Stenomax fundator Reitter, 1908 and Cylindronotus strangulatus Reitter, 1922 are designated. Molecular phylogenetic analyses were also conducted using mitochondrial COI sequences, in order to confirm the monophyly of the newly collected material of

A. amasiae from different populations. Taxonomic history, distribution, morphology, position of the genus in the tribe Helopini and key to species are given.

The genus Armenohelops Nabozhenko, 2002 was erected for two species from Armenia and Eastern Turkey [Nabozhenko, 2002]. Later one additional species from Iran [Nabozhenko, 2009] and two species from Anatolia were described [Nabozhenko, 2011]. Some species from Turkey including early to the genus Odocnemis Allard, 1876 [Nabozhenko, 2008] also belong to the genus Armenohelops after the study of the type material [Nabozhenko, Keskin, 2016]. One species A. terminasianae Nabozhenko, 2011 was transferred to the genus Odocnemis after the study of males from the type locality [Nabozhenko, Keskin, 2016]. Eight species of the genus are distributed in Northern Iran, Armenia and Turkey (Anatolia and East Thrace). The group reaches the most diversity in Anatolia from which 7 species are known, one species is known from Iran. Armenohelops was not found in South-Western Anatolia. The most of the species (3) are distributed in North Anatolian Mountains


from Rize and Artvin provinces to Istanbul, three species inhabit mountains of Eastern Anatolia (Kars, Erzurum, Van provinces) and Armenia, one species is described from northern slopes of Central Taurus.

Position of the genus in the tribe Helopini. Armenohelops belongs to the ‘cylindrinotoid’ generic group of the subtribe Cylindrinotina and is closest to the genera Idahelops Keskin et Nabozhenko, 2012 and Odocnemis. Species of the genera Idahelops and Armenohelops have unusual for the most Helopini structure of aedeagus: the apical piece is very short (4.5–5 times shorter than the basal piece) and curved, concave dorsally, with dorso- ventrally flattened apex; the basal piece is long. Idahelops is more specialized monotypic genus which differs from Armenohelops by the presence of large elytral tubercles with coeloconic sensilla, completely pubescence body and wide epipleura with dorsal carina flattened apically. Both genera differ from Odocnemis and other ‘cylindrinotoid’ genera (Cylindrinotus Faldermann, 1837, Reitterohelops Skopin, 1960, Microdocnemis Nabozhenko et Keskin, 2010, Taurohelops Keskin et Nabozhenko, 2015) also by female genital tubes with ‘nalassoid’ structure (the spermatheca is short and not brunched, without short processes, the accessory gland is short, basal duct of spermatheca is absent or very short). Males of Armenohelops have not teeth or granules on the inner side of tibiae unlike Cylindrinotus, Odocnemis and Microdocnemis. The main differences of Armenohelops and Taurohelops in outer morphology are in the structure of the abdominal ventrite 5 and male genitalia, absence of large dense elytral tubercles and not keel-shaped 8th elytral interval.

Bionomics. Imago of all Armenohelops are lichenophagous and feed on foliose lichens on tree trunks or rarely stones. Although their larvae are still unknown, they are probably soil dwelling as the most of other Helopini larvae. The most species are associated with flora of relict type and inhabit forests of Quercus cerris (A. amasiae (Seidlitz, 1896),

A. kasatkini Nabozhenko, 2013, A. fouquei sp. n.), Quercus castaneifolia (A. medvedevi Nabozhenko, 2009), Pinus nigra (A. amasiae, A. kagyzmanicus Nabozhenko, 2002,

A. armeniacus Nabozhenko, 2002) and Cedrus libani (A. amasiae). Imago of A. amasiae and A. fouquei sp. n. are also collected on Populus and Crataegus near forests of Quercus cerris. Species of Armenohelops were not found

on other species of Quercus (except listed). Some species inhabit open landscapes where feeding on epilithic foliose lichens (sometimes A. armeniacus, Armenohelops sp. from Ovit Pass, Rize Province). Imago are nocturnal and active from 20:00 to 1:00 in spring and early summer (April – June, until July in high mountains).

Material and methods

The study is based on the examination of adult beetles from the following institutes, museums and private collections:

HNHM – Hungarian Natural History Museum (Ottó Merkl, Budapest, Hungary);

MNHP – Muséum National d’Histoire Naturelle (Antoine Mantilleri, Paris, France);

NMB – Naturhistorisches Museum Basel (Eva Sprecher, Basel, Switzerland);

SMNS – Staatliches Museum für Naturkunde (Wolfgang Schawaller, Stuttgart, Germany);

ZIN – Zoological Institute, Russian Academy of Sciences (Gleb Medvedev, Mark Volkovitsh, St. Petersburg, Russia);

CK – private collection of Mark Kalashian, Scientific Centre of Zoology and Hydroecology of the National Academy of Sciences of Armenia (Yerevan);

CN – private collection of Maxim Nabozhenko.

We used Zeiss Supra 55VP Field Emission Scanning Electron Microscope in MEİTAM (Mersin University) and SEM Quanta 250 (Izmir Institute of Technology) for SEM images.

Molecular analyses. Although the specimens of

A. amasiae from different populations have identical structure of male genitalia, they show great variations in the length of tarsi, punctation, elytral interval and form of the pronotum. In order to confirm the monophyly of the newly collected material on A. amasiae from different populations, molecular phylogenetic analyses were conducted using mitochondrial COI sequences.

A total of 18 specimens were selected for DNA sequencing, representing different populations of

A. amasiae, A. armeniacus, A. parvocularis sp. n., and

A. fouquei sp. n. Turkonalassus petrophilus (in litt.) was used as outgroup taxon. Genomic DNA was extracted

from thorax, using the Promega 96-well plate kit according to the manufacturer’s instructions. An 829 bp fragment of the 3end of the cytochrome oxidase I (COI) gene was amplified using the primers JerryTen and PatTen [Papadopoulou et al., 2009]. Amplification products were purified and then sequenced in both directions, using the amplification primers. Sequence chromatograms were assembled and edited using Sequencher 5.0 (Gene Codes, Ann Arbor, MI). Sequence evolution models were selected in JModelTest 2.1.6 [Darriba et al., 2012] using the Bayesian Information Criterion (BIC). Tree searches were performed with Bayesian analysis by applying GTR+G model in MrBayes 3.2 [Ronquist et al., 2011] with two parallel runs of 10 × 106 generations, sampling a tree every 1000 steps. Standard convergence diagnostics were checked to ensure that the Markov chain had reached stationary phase using Tracer v1.4.1 [Rambaut, Drummond, 2007]. The first 25% of sampled trees were discarded as burn-in and the remaining trees were used to generate a 50% majority rule consensus tree. A list of specimens that were used in phylogenetic analyses is given in Table 1. The COI sequences were submitted to GenBank for accession numbers.

1.9 (Tokat: Türkfındıcak), 2.3 (Gümüşhane), 2.4 (Kastamonu: Ilgaz Dağları), 2.8 (Artvin: Şavşat).

Population from Türkfındıcak (Erbaa, Tokat): punctation of head very coarse, with connected punctures; punctation of pronotum coarser; body darker and less shiny.

Population from Artvin (Şavşat): legs more slender and longer; punctation of elytral intervals coarser.

Population from Gümüşhane (Zigana Pass, Köse) and Trabzon (Maçka): body larger, pronotum in base visibly shorter than elytra in base; male elytral intervals flat; punctation of pronotum and elytral intervals coarser; females with more projected anterior angles.

Population from Kastamonu (Ilgaz Dağları): body is less convex, legs more slender.

Populations from pass between Sorgun and Aydıncık and Çampınar (Çorum / Yozgat provinces border) clearly differ from other populations by widened protarsi of male, wider and more cordate pronotum of male, coarse transverse wrinkles on male prothoracic sternite.

Bionomics. The species inhabits forests with Quercus cerris, Pinus nigra, Cedrus libani and feed on foliose epiphytic lichens at night (from 21:00 to 1:00 a.m.).

Distribution. Northern Anatolia from Ankara and Kastamonu to Artvin Province.

Notes. We studied also one female from Rize Province (Anatolien: Ovitdag-Gec. 21.05.1989, leg. A. Riedel; deposited in SMNS) which is similar to A. amasiae. This specimen has clear differences from A. amasiae in the sculpture and punctation of pronotum, visibly flattened body, structure of elytral striae but we don’t want to

describe a new species in this taxonomically difficult genus before the study of males.

Molecular analyses

Bayesian analyses of COI sequence data representing different populations of A. amasiae, type species of the genus A. armeniacus, A. parvocularis sp. n. and

A. fouquei sp. n. resulted in three clades (Fig. 58). All

the studied species of Armenohelops were recovered as monophyletic with strong support in BI analysis. The specimens identified as A. amasiae from different populations were clustered together with a high nodal support value (PP = 1). Armenohelops parvocularis sp. n. was recovered as sister to A. amasiae with a high support.

Although all the studied material of Armenohelops was recovered as monophyletic with strong support in BI analysis, these preliminary findings need to be tested with complete sampling of Armenohelops species using different phylogenetic methods. Data from additional loci would be also necessary for reconstruction of the phylogeny of the genus Armenohelops and delimiting species boundaries.
