5. Agonochaetia lvovskyi Bidzilya, 2001

( Figs 6 , 32 )

Agonochaetia lvovskyi Bidzilya 2001:162 . Type locality: Shebalino , Altai, Russia. Povolný (2002a: 105).

Material examined. Holotype ♂ “ Russia, Altai, Shebalino, 22 Jun 1998, A.L. Lvovsky leg.” ( ZIN); 1 ♂, [ Russia], Gornyi Altai, Ongudai.[sky] r-n, middle stream of Inja river, 28 Jun 1989 ( Artemieva ) (gen. slide 163/15, O. Bidzilya) ( ZMKU) (examined).

DNA Barcode BIN. Not barcoded.

Adult ( Fig. 6 ). Wingspan 13–16 mm. Head and thorax grey brown. Labial palpus recurved, segment 2 brown, outer and upper side mixed with light grey, inner surface light grey to white, segment 3 brown mixed with white; Antenna light brown. Forewing nearly uniform brown to black, mottled by dark and ochreous scales. Indistinct oblique light brown fascia extending from the base of wing towards to anal angle; diffuse pale costal and tornal spots on ¾, black spots in fold, two indistinct markings in cell. Cilia light brown. Hindwing almost black, as dark or darker then forewing, with grey cilia.

Male genitalia ( Fig. 32 ). Tegumen sub-triangular in basal half, with broad, evenly arched anterior notch (TGN/TGL = 0.41). Uncus elongate, narrowed apically, with triangular incision at the top. Gnathos ring-shaped. Valva broad, widened medially, apex pointed, extending over the top of uncus. Sacculus 2–2.5x narrower and about 1/3 shorter than valva, curved inwards in distal 1/3, with small apical thorn. Posterior margin of vinculum with short medial humps, medial incision narrow, lateral projections broadly rounded. Saccus slender, about as long as tegumen and uncus. Glandiductor lobe needle-shaped, about length of phallus, weakly broadened at base. Phallus slender, straight, apex with triangular arm, distinctly longer than saccus, caecum weakly swollen, about 1/5 length of phallus ( Bidzilya 2001; Povolný 2002a).

Female genitalia. Unknown.

Diagnosis. Superficially A. lvovskyi is characterized by dark, nearly black, rather than brown, forewings. In male genitalia, A. lvovskyi differs from other Agonochaetia by the broader cucullus with an acute apex, long and extremely thin saccus (SAL /VLL = 0.87), and short, square, almost truncate, vincular lobes.

Biology. Unknown. The holotype and another male were collected in late June.

Distribution ( Fig. 43 ). Russia: Altai.

Remarks. The glandiductors of the only dissection available, illustrated in Fig. 32 , have broken tips. Their probable relative length was inferred from memory by OB.
