Asthena anseraria (Herrich-Schäffer, [1855]) View in CoL

Material examined: Ordu, Perşembe, Çaytepe, 200 m, 30.04.1996 1 ♂; 15.08.1996 1 ♀ 2 ♂ ♂ ; 22.08.1997 1 ♀; 15.08.1999 1 ♀ (genital slide number: GP0011 , GP0032 , GP4516 , GP4532 , GP4990 ) .

Description:

Imago: Wingspan 17–18 mm. Ground color of fore wings white, smoothly scaled. Discal spots black and very distinct. Transversal lines light yellowish brown, wavy and diffuse. Terminal dots darker than transversal lines. Fringes white. Hind wings with the same color and markings of fore wings. Vertex, thorax, and abdomen in white color ( Figure 1a View Figure 1 ).

Male genitalia: Uncus indistinct. Labides distinct and hairy. Valva broad and hairy, the hairs longer towards basal half. Basal half of costal margin slightly convex. Sacculus with large extension and basal lobe. Basal lobe covered with dense small hairs ( Figure 1b View Figure 1 ). Vesica with two separate cornuti tails ( Figure 1c View Figure 1 ).

Eupithecia selinata Herrich-Schaeffer, 1861

Material examined: Ordu, Perşembe, Çaytepe , 250 m, 30.04.1996 1 ♂; 200 m 12.08.1996 2 ♀♀ (genital slide number: GP4519 , GP4520 , GP4571 ) .

Description:

Imago: Wingspan of male 17.5 mm, female 20 mm. Labial palpi gray. Frons pale gray. Fore wings brownish gray, costal margin darker, transverse lines not significant, medial and terminal band slightly darker than ground color. Medial line very sinuate, postmedial line waved, discal spot large, dark, conspicuous, and ovate. Hind wings same color as fore wing, only slightly paler, apical part darker, transverse lines more significant than fore wings, discal spot distinct and small. Fringe paler and brownish gray ( Figure 2a View Figure 2 ).

Female genitalia: Bursa copulatrix elongated, strongly sclerotized, almost one-third covered by spines, marginal spines largest, with a row of strong spines on a hard sclerotized area in the right side, margin longitudinal to colliculum, end of this sclerotized area with a small appendix underside colliculum. Colliculum like collar, short and broad. Ovipositor small ( Figure 2b View Figure 2 ).

Male genitalia: Valva large and elongated, without ventral process, basal half of costal margin slightly convex ( Figure 2c View Figure 2 ), Vesica with two short horn-like cornuti. One of them medially more long than the other apically. Ejaculatory duct with a small cornutus basally ( Figure 2d View Figure 2 ). Sternum A8 elongated, enlarged basally and with deep medial indentation, apically broadened and with two small projections at corner ( Figure 2e View Figure 2 ).

In this study, Asthena anseraria (Herrich-Schäffer, [1855]) and Eupithecia selinata Herrich-Schaeffer, 1861 are recorded for the first time in the geometrid fauna of Turkey. Hausmann and Viidalepp (2012) gave Georgia as the only distribution area of A. anseraria outside Europe (1♀ from ‘Achalzich, leg.Korb’; ZSM, dissected). This record shows that this species is able to distribute as isolated populations around the Black Sea.

E. selinata is a Eurasian species, which is widespread mainly in South and Central Europe from the Pyrenees to the Urals and its distribution continues from the Urals to China and Japan. E. selinata is also found in the northern Caucasus as a separate population. Habitat requirements of this species are predicated as open deciduous, coniferous, and mixed forests; small forest clearings; and scrubcovered meadows ( Mironov, 2003). The present study area, Ordu, is located on the coastline of the Black Sea and has similar habitat characters to those that Mironov describes. Therefore, E. selinata should be accepted as a separate population throughout the Black Sea Region of Turkey.
