Saliocleta puyak, Pellinen, 2017

Pellinen, Markku J., 2017, Description of a new species of Saliocleta Walker, 1862 (Lepidoptera, Notodontidae, Spatalinae, Ceirini) and description of S. notia Schintlmeister, 1997 female from Thailand, Zootaxa 4353 (3) : -

Saliocleta puyak sp. n.

(Figs. 1 and 6)

Diagnosis. Externally this species resembles S. notia Schintlmeister, 1997 ( Fig. 2 ) having a similar forewing pattern, but is distinquished by a stronger and broader brown stripe running from base to apex in the forewing. The forewing ground colour of is more uniform in S. notia than in S. puyak . Saliocleta postfusca Kiriakoff, 1962 (Fig. 4) resembles also the the new species, but again its forewings are more uniform. Male genitalia differ: the uncus of S. notia (Figs. 10 a and c) is more even and the socii are flaplike. There is some resemblence in the uncus of the male genitalia to S. widagdoi Schintlmeister, 1994 ( Figs. 3 and 7a ), but S. widagdoi has flap-like socii not straight. Also externally S. widagdoi is clearly different from S. puyak , having an angeled forewing tornus, in S. puyak it is rounded. Saliocleta nonagrioides ( Fig. 5), has also an angeled forewing tornus.

Description. Male (Figs. 1 a, b) Forewing length 19-20 mm, wingspan 40–43 mm (5 exx.). Ground colour light brown with dark suffusion. Forewing veins M2, M3 and CuA1 white or yellow in mid part of wing dark medial spot is strong. Forewing with clear brown stripe running from base to apex with veins M2, M3 and CuA1 white or yellow in mid part: a white dash above mid part of brown stripe. Lines of dark submarginal, marginal and postmedial spots on veins. A strong black medial spot is present in forewing: tornus somewhat angeled. Hindwing uniformly blackish brown. Underside uniformly brown grey. Abdomen densely scaled, dorsally same colour as hindwing, except two terminal segments light grey. Cteniophore present on fourth sternite (all Saliocleta species have cteniophores). Eight sternite with sclerotized mesall progress, central fovea mushroom-shaped, tergite eigth bilobed with a small notch between lobes (Fig. 6 c). Male genitalia (Figs. 6 a, b). Vinculum semicircular, apically pointed; tegumen hood-like; valva moderately long and broad, apex rounded, valva bearing easily detached long hair-like scales; these scales especially abundant on sacculus (called the Barth organ ( Miller, 1991); juxta circular, tightly surrounding aedeagus; uncus arrow head shaped, margin bearing short bristles; socii lanceolate; aedeagus (Fig. 6 b) stout tubular; vesica with spine-like and stellate cornuti close to base of gonopore.

Female unknown.

Distribution and Bionomics. Known from South Thailand Chumphon province and North Thailand Tak and Lampang provinces and also from Laos. Specimens were flying in late April–June and late September–early December at 200 – 800 m in mixed forest with bamboo. Immature stages are unknown.

Etymology. The new species is named after Puyak mountain where specimens were captured on the lower slopes.
