RAZOWSKI et al. fragments, especially the cytochrome oxidase gene (COI). For example, the phylogenetic relationships of Argyrotaenia franciscana were determined by analysis of a mitochondrial DNA fragment containing the genes COI and COII (2300 bp) (LANDRY et al. 1999). A similar analysis using the COI segment was carried out by com-paring sequences obtained from closely related species of the genus Archips (KRUSE & SPERLING, 2002). A 940 bp COI fragment was applied to dis-criminate between two forms of Adoxophyes orana feeding on different food plants in the Adoxophyes species complex (LEE et al. 2005). A combination of morphological and molecular data was useful for verification of the systematic position of the European Tortricini (RAZOWSKI et al. 2010) and for resolving uncertain relationships be-tween tribes Bactrini and Endotheniini (RAZOWSKI & TARCZ 2012). However, such analyses have not been applied to Neotropical Torticidae genera. For the first time genus Orthocomotis was de-scribed for one Neotropical species. Orthocomotis didn’t have a tribal placement and was treated as a member of Tortricinae. CLARKE (1955) was the first to revise the genus and included in it 29 spe-cies (12 previously known and 17 newly described species). His supposition that Orthocomotis is a genus was confirmed by further studies (RAZOWSKI et al. 2007). Then RAZOWSKI (1982) transferred Orthocomotis to Polyorthini, a tribe of the subfamily Chlidanotinae based on the following synapomorphy: a minutely bristled dorsal portion of the anellus situated immediately above the aedeagus, con-nected with the aedeagus and transtilla. According to POWELL (1986) this genus belongs in Euliini. However, POWELL (1986) based his analysis only on some synplesiomorphies of the genitalia. Finally BROWN (1989) transferred Orthocomotis and its closely related genus Paracomotis RAZOWSKI, 1982 to Schoenotenini based on the chaetosema situated on the vertex of the head. He also confirmed a previous hypothesis (DIAKONOFF 1974) that the most important character of Polyorthini is the presence of the outer slit of the valva and its associated corema (a scalepencil from the terminal part of the abdomen concealed in a slit). However, there are many closely related species of Chlidanotinae with a secondarily re-duced abdominal scent organ. Recently, there was a consensus that the dis-cussed genus belongs to Euliini (HORAK 1999; HORAK & BROWN 1991; RAZOWSKI 2008) al-though RAZOWSKI and BECKER (1999) suggested that the true phylogenetic placement of Orthocomotis requires further study. The purpose of the present study is to elucidate this issue. In the present paper we compared several spe-cies of Orthocomotis forming a compact grouping and used four representative species. We com-pared Orthocomotis with six species of Polyorthini and Palaearctic Eulia ministrana, the type-species of the genus Eulia, and five representatives of the Neotropical Euliini. In the Palaearctic there is another species (Pseudargyrotoza conwagana FABRICIUS, 1775) but there are some objections if it belongs to Euliini (HORAK 1999). In the Neotropics there are numerous species of Euliini which are included in the tribe on the basis of presence of the pedal scent organ. Because of the uncertain position of Orthocomotis, we proposed a preliminary molecular approach as a tool for resolving this taxonomic problem. The present paper is the first comparative molecular study of representatives of the studied species. Material andMethods Material The examined specimens were collected by Janusz WOJTUSIAK and Volker PELZ in Ecuador and are preserved in the collection of the Zoologi-cal Museum of the Jagiellonian University, Krakw (MZUJ) and the Volker PELZ collection. Due to problems associated with obtaining good quality DNA suitable for molecular analysis, COI sequences of Eulia ministrana were taken from GenBank. Representatives of the tribe Olethreutini i.e. Apotomis inudana, Apotomis sauciana, Olethreutes arcuellus were used as outgroups. A list of examined taxa arranged alphabetically is presented in Table 1. Molecular methods DNA was extracted only from two hind legs of dry specimens because some of them were mu-seum material (it was impossible to use other parts of the bodies – e.g. the entire tagmata) and preserved in 70% alcohol. The examined specimens were not older than 10 years and were first identified by comparison of the genitalia. Specimens over ten years of age usually gave insufficient re-sults. The best results were obtained from 1-3 year old individuals preserved in 70% alcohol. Genomic DNA was isolated without protocol modification using the NucleoSpin Tissue Kit (Macherey-Nagel, Germany). To elute purified DNA we applied 100 Fl of Elution Buffer (EB) onto the silica membrane.

RAZOWSKI et al. mitochondrial COI gene (650bp) the following primer pair designed for Lepidoptera was used: LEP-F1, 5’-ATTCAACCAATCATAAAGATAT-3’; and LEP-R1, 5’-TAAACTTCTGGATGTCCAAAAA-3’. These are universal primers used for species identification in DNA barcoding (HEBERT et al. 2004). PCR amplification of both markers was carried out in a final volume of 40 Fl containing: 4 Fl of template, 1.5 U Taq-Polymerase (EURx, Poland), 0.8 Fl of each 20 FM primer, 10x PCR buffer, 0.8 Fl of 10mM dNTPs in a Mastercycler ep (Eppendorf, Germany). The amplification protocol was the same as in (HEBERT et al. 2004). To check amplification, 10 Fl of each PCR product was electrophoresed in 1% agarose gel for 45 min at 85V with a DNA molecular weight marker (Mass Ruler Low Range DNA Ladder, Fermentas, Lithuania). For purification of PCR reactions we used NucleoSpin Extract II (Macherey-Nagel, Germany). In some of the PCR reactions apart from main band additional sub-bands were obtained. In these cases 30 Fl of each PCR product was separated on a 1.8% agarose gel (100V/60min). Then, the band representing the examined fragment was cut out and purified. Cycle sequencing was done in both directions with the application of BigDye Terminator v3.1 chemistry (Applied Biosystems, USA). Primers LEP-F1 and LEP-R1 were used for sequencing. Each sequencing reaction was carried out in a final volume of 10 Fl containing: 3Fl of template, 1Fl of BigDye Master Mix (1/4 of standard reaction), 1Fl of sequencing buffer, 1Fl of 5FM primer. Se-quencing products were precipitated using Ex Terminator (A&A Biotechnology, Poland) and separated on an ABI PRISM 377 DNA Sequencer (Applied Biosystems, USA). Sequences are available in the GenBank database (for accession num-bers see Table 1). Data analysis Sequences were examined using Chromas Lite (Technelysium, Australia) to evaluate and correct chromatograms. The alignment of the studied se-quences was performed using ClustalW (THOMPSON et al. 1994) within the BioEdit software (HALL 1999). Phylograms were constructed for the studied fragments with Mega v5.0 (TAMURA et al. 2011) using neighbor-joining [NJ, (SAITOU & NEI 1987)], maximum parsimony [MP, (NEI & KUMAR 2000)], and maximum likelihood [ML, (FELSENSTEIN 1981)]. NJ analysis was performed using the Kimura 2-parameter correction model (KIMURA 1980) by bootstrapping with 1000 replicates (FELSENSTEIN 1985). MP analysis was evaluated with the min-min heuristic parameter (at level 2) and bootstrapping with 1000 replicates. Bayesian in-ference (BI) was performed with MrBayes 3.1.2 (RONQUIST & HUELSENBECK 2003); the analysis was run for 5,000,000 generations and trees were sampled every 100 generations. All trees were ex-amined with TreeView 1.6.6 (PAGE 1996). Analysis of haplotype diversity, nucleotide diversity and variable nucleotide positions was done with DnaSP v5.10.01 (LIBRADO & ROZAS 2009). Analysis of nucleotide frequencies, p-distance es-timation and identification of substitution model (GTR+G+I for COI mtDNA fragments) for ML analysis were done with Mega v5.0 (TAMURA et al. 2004, 2011). Results andDiscussion A total of 19 sequences of the gene encoding cy-tochrome oxidase subunit I (606 bp) from species of Euliini, Polyorthini and Olethreutini were used in this study. Of these, 13 were newly obtained while the remaining sequences were taken from GenBank. The interspecific haplotype diversity value was Hd=1, indicating substantial variability of the studied DNA fragment. Nucleotide diversity amounted to B=0.1114. The nucleotide frequencies were A=0.3119, T=0.3716, C=0.1554 G=0.1611 and revealed a high proportion of A-T pairs which corresponds with typical characteristics of insect mitochondrial DNA. Mean divergence over all studied Tortricidae (N=19) sequence pairs was p=0.111/SE=0.007 (p-distance/standard error). Mean divergence over all studied Euliini (N=10) sequence pairs was p=0.113/SE=0.008 and Polyorthini (N=6) (p=0.076/SE=0.007). More detailed information on divergences between particular species is presented in Table 2. We found 198 variable positions across all studied species in the COI fragment, 156 of which were parsimony informative (90 with two variants, 51 – three variants, 15 – four variants). A total of 19 haplotypes were found among the studied species. All constructed trees (Figs 1-3) showed the existence of three well separated clusters representing the particular tribes (Euliini, Polyorthini and Ole-threutini used as an outgroup). Orthocomotis al-ways appears in the Euliini cluster. In the case of NJ and MP, it forms a monophyletic cluster with closely related O. parandina and O. marmorobrunea, then O. oxapampae and most distant O. golondrina. The latter species in ML and BI trees appears together with Dimorphopalpa lyonsae. This could be connected with the applied COI gene which is a fast evolving genome fragment. This could be seen on the constructed trees: the terminal branches are very long with high boot Table2 ThenumberofbasesubstitutionspersitebetweensequencestheCOImtDNAfragment (lower-left)areshown.Standarderrorestimate(s)areshownabovethe diagonal.All resultsarebasedonthe pairwiseanalysisof19sequences of thestudiedTortricidae species.Analyses wereconductedusing theMaximum CompositeLikelihoodmodel inMEGA5 Studied species 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 1.

However, in the present analysis we were not able to obtain DNA sequences for other, more slowly evolving molecular markers. Nonetheless, all studied species of Polyorthini are well separated from each other and support the DNA barcoding hypothesis (HEBERT et al. 2003) that the COI fragment can be used as a universal molecular marker for species differentiation. As mentioned above, we obtained similar trees using ML and BI methods (Figs 2, 3) with one exception. Orhocomotis golondrina appeared as closely related to Dimorphopalpa lyonsae. The morphological approach contradicts this discrepancy but we cannot exclude that the two genera are related. This result may be thus regarded as preliminary and a further analysis with additional species of Dimorphopalpa and specimens of O. golondrina is required. This issue does not contradict the purpose of this paper, the inclusion of Orthocomotis in the Euliini. The two new species of Euliini: Galomecalpa le-sta RAZOWSKI & PELZ, sp. n., Gauruncus ischyros RAZOWSKI & PELZ, sp. n., do not seem to be closely related (Figs 1-3). Galomecalpa lesta ap-pears together with Eulia ministrana, the type spe-cies of Euliini, on NJ, MP or ML trees but on BI tree is in one cluster with Seticosta sp. On the other hand, in all analyzed trees Gauruncus ischyros (Figs 1-3) is closely related to Oregocerata rhyparograpta. Our molecular study confirms the supposition by BROWN (1989) that Orthocomotis seems to be a genetically differentiated genus belonging to Euliini and is not directly related to Polyorthini. This large genus, certainly with unexamined Paracomotis RAZOWSKI, 1982 constitutes, however, a distinct clade and probably the sister group to other Euliini. There are some morphological characters that differentiate between Euliini and Polyorthini. The valvan slit correlated with the corema is always ab-sent in the discussed genus but a lack of the slit is also noted in several Polyorthini and the two re-maining tribes of Polyorthinae. Instead, males of Orthocomotis have a developed anterior abdominal scent organ not found in Polyorthini but occur-ring in several genera of the Tortricidae, e.g. in Pandemis HÜBNER, Tortricinae and Lobesia GUENÉE, Olethreutinae. However, the pedal scent organ characteristic of Eulia HÜBNER is found in Atteriini. Apparently, the distribution of scent or-gans within the family is of convergent importance (legs, basal and terminal parts of abdomen are con-venient places for scent gland distribution). The microspined dorsal part of the anellus developed in Orthocomotis is widely distributed within Poly J. RAZOWSKI et al. orthini and the remaining tribes of Chlidanotinae. However, Orthocomotis lacks a distinctly sclerotized link between the juxta and disc of valva which are present in Polyorthini. A comparison of the system based on morphology of Tortricidae with molecular analysis of se-lected DNA fragments should facilitate the resolution of problematic relationships between species, genera and tribes. Furthermore, it will im-prove and complete the current system of Tortricidae classification, and should help in assessment of the frequency of cryptic species occurrence or sex identification in case of dimorphic species.

D i a g n o s i s. Galomecalpa lesta is closely re-lated to G. meridiana RAZOWSKI & BROWN, 2004 from Venezuela which was incorrectly recorded from Ecuador by RAZOWSKI & PELZ (2006) from the Napo Province but the latter with long, slender aedeagus similar to G. parsonsi RAZOWSKI & PELZ, 2006. The two Ecuadoran species are illustrated by RAZOWSKI & PELZ 2006. Etymology. The specific name refers to a forgotten species; Greek: lestis – oblivion. Gauruncusischyros RAZOWSKI & PELZ, sp. n.

Volker Pelz, 2 males (GU-3796-V.P., GU-3796-V.P.): Ecuador, Pichincha – Prov., 6 km S Santa Rosa, Las Gralarias, Damuth Choco Re-search Station, 2270 m a.s.l., 0°1’59" S 78°42’33" W, 8-9.XI.2007, leg. Volker PELZ. D i a g n o s i s. In facies, G. ischyros is similar to G. rossi RAZOWSKI & PELZ, 2006 from Pichincha, Ecuador but does not have the ferruginous shading of the forewing ground colour; in genitalia ischy-ros resembles G. armatus RAZOWSKI, & PELZ, 2006 but ischyros has short terminal process of the sacculus and slenderer arms of the uncus. E t y m o l o g y. The specific epithet refers to heavily sclerotized, large parts of genitalia; Greek: ischyros – strong. Fig. 4.
