New species can be distinguished by well-developed sacculus with trapezoidal distal part and serrated dorsal margin and by tube-like aedeagus by the same width throughout, with basal part curved dorsally in the male genitalia; and heart-shaped postvaginal plate, long and narrow sclerotized antrum and corpus bursae without signum in the female genitalia. Figs 1–3. Laszlogozmanya eclecticus sp. n. , male 1 – adult, holotype; 2 – wing venation; 3 – 2nd abdominal sternite. DESCRIPTION. Adult ( Fig. 1 ). Forewing length 5.5-6.5 mm. Head whitish grey. Antenna slightly shorter than 3/4 of forewing length, scape dark grey on upper side and light grey on lower side, flagellum dark grey. Labial palpi with fuscous first segment, second segment dark grey in basal 2/3 and light grey distally, third segment slightly shorter than second one, with dark ring on the whitish basal half, with fuscous distal half and whitish apex. Thorax mainly grey, with tegula fuscous anteriorly. Forewings light grey, costal margin with six dark dots – two ones on the basal part (at the base and 1/5 of wing length), another four ones along distal part of costal margin; series dark dots placed along external margin from apex to tornus; two dark sports, like merged two-three dots, on the longitudinal axis of wing – larger spot at 1/3 and smaller one at 3/5 of wing length; cilia light grey. Hindwing grey, cilia slightly lighter. Venation with R 4 and R 5 coincident, M 3 and Cu 1 connate, Cu 2 absent in the forewing; and with Rs and M 1 stalked, M 3 and Cu 1 stalked in the hindwing ( Fig. 2 ). Fore- and midlegs dark grey and hindlegs slightly lighter, with grey femur, each segment of tarsus with very narrow light ring distally; spurs of mid- and hindlegs grey with light apices. Abdominal 2nd segment with slightly sinuous venulae and drumstick-shaped apodemes. Figs 4–7. Laszlogozmanya eclecticus sp. n. , genitalia. 4 – male genitalia without aedeagus, juxta and anellus, medial view, holotype ; 5 – aedagus, juxta and anellus, holotype ; 6 – fragment of ventral part of the male genitalia (sacculi, dorso-basal processes of valvae, aedeagus, anellus), medial view; 7 – female genitalia, ventral view. Figs 8–10. Laszlogozmanya eclecticus sp. n. , functional morphology of the male geni- talia. 8 – dorsal view; 9 – ventral view, without aedeagus; 10 – aedeagus, juxta and anellus, hemitranstilla (dorso-basal process of valva), lateral view. Male genitalia ( Figs 4–6 ). Uncus elongated, lamellar with two small protrusions and a rounded notch between them at the apex, slightly dilated basally. Tegumen widened anteriorly, with semioval sclerotized curve at the middle of anterior part. Gnathos with narrow lateral arms and weak median hook. Valva indistinctly concaved at the middle of costa, dorso-basal process large and angular, curved inwards and joined with sclerotized anellus; sacculus almost separated from cucullus, consisting of strongly sclerotized more or less trapezoidal apical part with serrated dorsal margin and dense brush of strong spines on medial surface, and /\–shaped basal part, joined with juxta ventrally ( Fig. 6 ). Aedeagus tube-like, with elongated one-sided right wall in the distal part and base curved dorsally, vesica spinuliferous and lacking needlelike cornuti. Anellus strongly sclerotized, enveloped aedeagus by tube with long ventral lobe rounded apically ( Figs 5 , 10 ). Juxta gutter-like, fused with sclerotized anellus and joined with narrow ventral processes of sacculi. Vinculum fused with valva, as narrow arched sclerite with short saccus enlarged apically. Fig. 11. Laszlogozmanya eclecticus sp. n. , functional morphology of the male genitalia, unrolled view, aedeagus removed. Female genitalia ( Fig. 7 ). Ovipositor very short, papillae anales sclerotized basally. Apophyses anteriores slightly shorter than apophyses posteriores. Posterior margin of the eighth tergite concave at the middle. Eighth sternite with heart-shaped postvaginal plate. Ostium relatively small, equal to antrum in diameter, placed anterad the heart-shaped postvaginal plate; antrum very narrow and tube-like, sclerotized on the left side, its length is almost equal to rest membranous part of ductus bursae; the latter slightly wider than antrum; ductus seminalis is arising from boarder between sclerotized and membranous parts of duсtus bursae. Corpus bursae membranous and oval, without signum. DISTRIBUTION. Russian Far East (Primorskii krai: Furugelm Island.). ETYMOLOGY. The specific name, eclecticus , is derived from Greek ἐκλεκτός, meaning a mix or combining heterogeneous characters (in this case) and refers to the morphology of the described species, external features and genital characters of which are typical for genera belonging to different subfamilies of the family.
