Figs 88–92, 98, 99, 102
Mella yerburii Butler, 1884 — Proceedings of the General Meetings for Scientific Business of the Zoological Society of London, 502. TL: Aden, Yemen.
Type material examined. ♀, [Yemen] “ Aden, 84.43 (41)” | “45” | “ Type ” (NHM).
Other material examined. Tunisia: 2 ♂, 1 ♀, Hung. Zool. Miss., 21 km NW El Kef, 700 m, 28.iii.1977, No. 25 (Embey-Isztin, Gozmány & Mahunka) (gen. slide 347/ 19♂; 348/ 19♀, 33/ 20♂, O. Bidzilya); 1 ♂, Hispania, Alhama de Murcia, 6.v.927 (Escatera) (gen. slide 267/19, O. Bidzilya) (all NHMB). Russia: 12 ♂, 1 ♀, Astrakhan region, Khosheutovo vill. 23 km NE, 47°10’11’’, 48°02’50’’, 17.v.2017 (ET). Kazakhstan: 1 ♂, 1 ♀, Turkestan reg., 33 km NE of vill. Sozak, sands, 26.vi.2019; 1 ♂, Mangistau reg., vill. Sai Otes 9 km SW, canyon, 6.vi.2017; 6 ♂, Mangistau reg., vill. Taushchik 10 km NE, 11, 12.v.2016; 5 ♂, 1 ♀, Mangistau reg., Beineu 11 km N, bank of the river, 15.v.2016 (all ET).
Diagnosis. Long cilia on flagellomeres is reliable character for separating males of A. yerburii from other Ancylosis species except for A. ciliatella, A. pectinatella and A. labeculella. The species is characterized additionally by contrasting, blackish-brown forewing mottled with white and distinct white subcostal strip edged by blackishbrown irroration along costal margin broadened before apex. Straight rather than medially bulged ventral margin of valva is the most constant character for separating of A. yerburii from A. cliatella, A. pectinatella and A. labeculella. The species differs additionally from A. ciliatella in ductus ejaculatorius placed much closer to middle of aedeagus (closer to end of aedeagus in A. ciliatella). In females of A. yerburii thorn-like signae are larger and less numerous than those of A. ciliatella, and ductus bursae is ovate rather than rounded. Ancylosis pectinatella has extremely similar female genitalia except for longer antrum (Fig. 101).
Remarks. Mella yerburii was described based on unspecified number of specimens from Aden. The female labelled as “type” from NHM should most likely be considered as a lectotype. The current diagnosis of A. yerburii is based on specimens from Northern Africa and Iran externally similar to the type specimen. However, this diagnosis is rather provisional until the genitalia of the type specimen remain unexamined and additional material from type locality is unavailable.
Distribution. Algeria, Tunisia, Libya, Egypt, Yemen, Iran (Roseler 1973; Leraut 2014), Kazakhstan (first record), Russia (Astrakhan region) (first record).
