Type material.
Holotype male. China, Sichuan, 29°52.808'N, 102°50.240'E, near Ying Jing, bamboo forest, 700 m, 4.IV.2011, leg. Floriani; slide No.: OP1429m (coll. O. Pekarsky, deposited in the HNHM Budapest). Paratypes. China, Sichuan: 4 ♂♂, with same data as the holotype (coll. A. Saldaitis, Vilnius); 1 ♂ (coll. O. Pekarsky); 1 ♂ (coll. W. Speidel, Munich).
Etymology.
The species name refers to the resemblance of the opened male genitalia to a pelican.
Diagnosis.
The new species possesses a number of the diagnostic characters of the genus Schrankia (e.g., absence of ocelli; long, straight palpi; wide valval base; presence of medial complex of processes; thin, elongated aedeagus). The autapomorphic features of Schrankia pelicano are the very long palpi, being much longer than in other species of Schrankia , the biarticulate uncus, the extremely large sacculus, which is almost equal in size and similar in shape to the distal half of the valva. Considering the diagnostic characters mentioned previously, the new species is placed into Schrankia , but its generic position could change through a much needed revision of the entire genus. Among Schrankia , the new species is closest to the Oriental group of species known from Korea and Japan, Schrankia separatalis , Schrankia dimorpha , Schrankia kogii , Schrankia masuii and Schrankia seinoi . This species-group is characterized by the flat, thin, weakly sclerotized (almost transparent) distal half of valva, which has a rounded apex, wider and more strongly sclerotized haunch-like valval base, the well-developed apical saccular projection, and the less broadened caecum. The numerous autapomorphic features of the male genitalia of the new species (Figs 5-7) make it difficult to determine its closest relative within Schrankia . The comparison is provided here with Schrankia taenialis (Fig. 8), the type-species of the genus and Schrankia separatalis (Fig. 9), the most similar representative of the Oriental group of species. Schrankia pelicano is similar externally to Schrankia taenialis and Schrankia separatalis (Fig. 4) but has longer labial palpi, narrower, more elongated forewing with a less acute apex and straight, almost parallel crosslines without undulations or dentations. The male genitalia of Schrankia pelicano differ from those of the related species by the long and narrow, subapically constricted valva, very large sacculus, digitiform ampulla, and basally clavate uncus with a long, narrow, acute distal part. Schrankia taenialis (Fig. 8) has a narrow valva with an acute apex, a large and broad ampulla and a long uncus. The genitalia of Schrankia separatalis have, in comparison with Schrankia pelicano , short and wide valva with small sacculus and much thicker, continuously curved uncus having half-cylindrical cross-section (Fig. 9).
Description.
Male (Figs 1, 2). Wingspan 16-17 mm, length of forewing 8 mm. Head, thorax and abdomen ochreous grey; ocelli absent; tongue well developed; palpi very long (almost 5 times longer than diameter of eye), straight, 2nd segment (with appressed scales) about 2.8 times longer than 3rd segment, which is porrect; antenna with fine ciliation ventrally along full length, basal joint without pectination. Forewing elongate, narrow with acute apex, outer margin with rounded termen; ground color grey brown; costa straight with five milk-white patches; basal line barely visible, semicircular; antemedial line black, straight, oblique, curved upward near costa; postmedial line black, straight, oblique, extending from 2/3 from base on hind margin of wing to 9/10 from base on costal margin, edged on outer side by narrow yellow postmedial fascia; subterminal line faint, pale, irregular, parallel to outer margin of wing; terminal line black, most prominent between wing veins; cilia yellow at base with dark medial line, grey distally. Hindwing ochreous grey, discal spot grey, terminal line black; cilia pale yellow at base, grey distally. Abdomen slender, long. Female unknown.
Male genitalia (Figs 5-7). Uncus biarticulate, consisting of clavate and setose main part and long, narrow, subapically curved, bill-like extension with pointed tip; tegumen narrow, as long as vinculum; scaphium well sclerotized, distally dilated; subscaphium membranous; juxta large, triangular, wider at base, weakly sclerotized (almost transparent), with two narrow, strongly sclerotized lateral plates with serrated inner edges (Fig. 6); vinculum strong, cup shaped. Valva elongated, conspicuously constricted subapically; cucullus almost rounded with acute tip; corona absent; sacculus very large, elongated, with very long, heavily sclerotized, distally dilated saccular extension, almost as long as distal half of valve; clavus unspecialised; clasper/ampulla complex large, sclerotized, setose, cuneate with broad base and finely pointed apex. Aedeagus tubular, thin and gracile, finely undulate. Vesica relatively short (shorter than aedeagus), thinly tubular (as broad as average width of aedeagus), with fine granulose scobination throughout.
Distribution.
The species is known only from the type-locality, South-West China, Province Sichuan.
