Abstract: A new species of the Schrankia Hübner, 1825, S. griffon sp. n. is described. A diagnostic comparison is made with Schrankia pelicano Pekarsky, 2012.

Key words: Hypenodinae, Schrankia, new species, Thailand

INTRODUCTION

The research on the Schrankia species of the Indo‐Pacific region was initiated by the recognition and description of S. pelicano from southwest China in 2012 (PEKARSKY 2012). The subsequent investigations led to the discovery of a new species from North Thailand, being closely related to S. pelicano. These two species represent a distinct, separate lineage within the genus, the pelicano species‐group.

SYSTEMATIC PART

Schrankia griffon sp. n. (Figs 5–8)

Type material. Holotype: Male (Fig. 5), North Thailand, Prov. Chiang Mai, Doi Phahompok, 20 km NW of Fang, 2150 m, 22–25.I.2004, leg. Attila Szabó, slide OP1785m (coll. HNHM). Diagnosis. Schrankia griffon differs externally from S. pelicano (Fig. 1) by its longer forewings with less straight but slightly undulate postmedial line and with well developed, strongly marked, dark patch‐like reniform stigma. In the male genitalia, S. griffon can be distinguished from S. pelicano (Figs 2‐ 4) by the considerably larger size of the clasping apparatus, the more massive main part and more curved extension of uncus, the larger and distally more dilated distally saccular extension of valva, and the longer and thicker ampulla.

Description. Male. Wingspan 18 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, 3rd segment porrect; antenna with fine ciliation ventrally along its full length, basal joint without pectination. Forewing elongate, narrow with acute apex, outer margin with rounded termen; ground colour grey‐brown; costa straight with five milk‐white patches; basal line barely visible, semicircular; antemedial line straight, oblique, curved upward near costa, black with light outer fascia; 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, irregularly zigzagged, its upper part more or less parallel with outer margin of wing; terminal line fine, whitish, followed by black streaks between veins; cilia as ground colour. Hindwing ochreous‐grey, discal spot grey, terminal line black; cilia pale yellow at base, grey distally. Abdomen slender, long. Female unknown. Male genitalia (Figs 6, 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, weakly sclerotized (almost transparent); vinculum strong, cup shaped. Valva elongated, somewhat constricted subapically; cucullus ovate 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 valva; clavus unspecialised; clasper/ampulla complex large, sclerotized, ampulla narrow, long, setose with broad base and finely pointed apex. Aedeagus tubular, thin and gracile, finely undulate. Vesica membranous. Distribution. The species is known only from the type‐locality, North Thailand, Province Chiang Mai. Etymology. The species name refers to the resemblance of the opened male genitalia to a griffon.
