External Morphology and Female Genitalia of Ethmia candidella (Lepidoptera: Ethmiidae) Recorded for the First Time from Erzurum (Turkey) İ lk Kez Kaydedilen Ethmia candidella (Lepidoptera: Ethmiidae )'nın Dış Morfolojisi ve Dişi Genital yası

Ethmia candidella (Alphé raky, 1908) samples r ecorded for the first time from Erzurum (Turkey) were collected with aspirator through the cracks and slits in Populus alba bodies in Atatürk University Campus in September 2017 -2018. A total of 21 female individual were obtained. Specimens were dissected and prepared female genitalia and wings slides in the laboratory. The external morphology and female genital ia of E. candidella were described in detail. In addition, eggs from fertilized females under the microscope were obtained .


Introduction
The Ethmiinae subfamily is a microlepidopteran group consisted more than 350 species in seven genera worldwide. The Ethmia genus includes 47 species groups. It also includes many species that are not assigned to species groups (Wei et al., 2007). In Europe, 29 species had been recorded until recently (Domingo, et al., 2003).
The first checklist study of moths from Turkish was listed by Kemal (2006, 2007).
In studying of Kemal (2006, 2007), a total of 4604 moth species were listed together with their synonymous and updated distributions. Later, Koçak and Kemal (2009) reported that the Turkey Lepidoptera fauna was 5128 species belonging to 76 families. In addition, a total of 764 lepidoptera species, 554 Heterocera and 210 Rhopalocera, belonging to the province of Erzurum, were listed by the same authors. In addition to this information, Ethmia genus has 24 species in Turkey in present, but the genus Ethmia was not recorded found in Erzurum (Koçak and Kemal, 2009).
Asperugo procumbens, Borago officinalis, Cerinthe majör and Lithospermum purpurocaeruleum are given as the larval hosts of E. candidella in URL-1.  stated in their study in Van (Bahçesaray) that E. candidella adults fly at night in autumn and their larvae hide under Boraginaceae (Echium, Anchusa) in spring.

Field Studies
Field studies was carried out in the Atatürk University Campus (1850 m) in September 2017-2018. All the field works were done under suitable weather conditions (without strong winds and precipitation), and started early in the morning and continued until sunset. Ethmia candidella specimens was collected with aspiratör on Populus alba (Figure 7a, b). In the field studies, totally 21 specimens were obtained ( Figure 7c).

Laboratory Studies
The specimens collected first were classified according to their body size without losing their body water. They were pinned to size 1 or 2 insect needles on special stretch boards and the front and rear pairs of wings were stretched in the laboratory. Stretched specimens were kept for fourteen days (two weeks) in a dark and dry place at room temperature to dry. After the morphological examinations and measurements of the female samples, the female genital organ was prepared for the identification of the species. The needling of the butterflies, stretching of the wings and genital organ preparations were made according to Atay (2006). The major taxonomic characters were described. Important
Antennae filiform and long, length 9 mm, densely covered with short cillia, its length 0,69 times longer than forewing length. Labial palpus long and well developed, strongly recurved upwards ( Figure 3b). Its length 1,70 times as long as ocular diameter. The first labial segment is slight oblique and long. The second segment is long, strongly oblique upwards. The third segment is the same length as the first segment. Maxillary palpus with small 4 segments, rather short and thin and last segment (fourth segment) longest. Haustellum is very long, its length as long as antennae length. Eyes are round, large and dark brown. Ocelli and chaetosemata absent. Forewings are long, narrow and ovalshaped, its outer margin convexly curved, its length 2,71 times longer than its width. Surface of the forewings white, with blackish spot. Under surface of the forewings more dull blackish gray colored.
Hindwings long and broad, its length 2,12 times longer than its width. Upper surface of the hindwings white and plain, and its apex light grayish. Under surface of the hindwings similar to the upper surface. Forewings 13 veined, with 2 anal veins. Hindwings 10 veined, with 3 anal veins (Figure 3c).

Female Genitalia
Papillae analis (ovipositor) is heavily sclerotized, long and slightly broad, with short and sparse setose. Apophyses posteriores long and thin; slightly longer than papillae analis. Segment VIII is sclerotized broad and medium length. Apophyses anteriores largely reduced. Antrum sclerotized long and narrow. Ductus bursae is extremely long, tubular and membranous. Corpus bursae rather big and broad, membranous with signum. Signum large and long, a spiny plate, subrhombic, and covered with more or less uniform teeth (Figure 4).

Conclusions and Recommendations
This species is new record for the the lepidoptera fauna of Erzurum. In this study, identifıed the genital and external morphology of the female E. candidella. The important taxonomic characters of E. candidella were redefined in detail by comparasion of different parameters with each other. Each one of the genital and external taxonomic characters were measured with sterio microscope and digital caliper. All individuals of the insect were obtained towards the end of September and consist of completely fertilized females. This situation shows us that the species hibernated the winter in the egg stage. The bioecology of the species should be revealed with more detailed studies in the future.
