Introduction

The genus Epilepia was established by Janse in 1931 to accommodate three species: the type species Macalla melanosparsalis Janse, 1922, E. melanobrunnea (Janse, 1922) transferred from Macalla, and E. simulata Janse, 1931. Later on, INOUE & YAMANAKA (1975) transferred M. dentatum Matsumura & Shibuya, 1927 and M. melanobasis Hampson, 1906 to Epilepia, and SPEIDEL (2007) described E. meyi from Nigeria.

Epilepia dentatum (Matsumura & Shibuya, 1927) described from Japan is the only species distributed in the Palearctic Region, which was recorded in China and Korea (LI et al., 2009). The aim of the present paper is to review three Epilepia species in China, including two new species.

Material and methods

Specimens examined in the present study were collected by light traps. Adults were examined using an Olympus SZX9 stereo microscope. Permanent mounting methods of genitalia and venation follow the techniques introduced by LI (2002). Images of adults were taken by using a Leica M205A stereo microscope and images of genitalia were taken by using a Leica DM750 microscope, and all refined in Photoshop CS5 software.

All the studied specimens, including the types of the new species, are deposited in the Insect Collection of Nankai University (NKU), Tianjin, China.

Taxonomic accounts

EpilepiaJanse, 1931

EpilepiaJanse, 1931: 466.

Type-species: Macalla melanosparsalis Janse, 1922, by original designation. Type locality: South Africa.

Generic characters: Body medium size. Head (Fig. 1): Labial palpus slender, first segment thicker than second, second segment with hair-like scales on ventral surface distally. Maxillary palpus short and compressed in both male and female (except long brush-like in male of E. dentatum). Antenna with short cilia on ventral surface in male, without scape extension; female antenna slightly thinner than male. Forewing (Figs 2-4) with discal and discocellular spots represented by a tuft; terminal line with evenly spaced spots along its inner side. Hindwing with metal flash near costal margin, with a short strip from upper corner to lower corner of cell. Wing venation (Fig. 5): Forewing with R3, R4 and R5 stalked; hindwing with Sc+R1 and Rs departed, M1 and Rs from upper angle of cell; both wings with M2 and M3 separated. Mid and hind tibiae with hair-like scales on outer side.

Male genitalia (Figs 6-8). Uncus elongate, often widened distally. Gnathos absent. Valva sub- ovate, with a sclerotized wavy fold from base reaching below dorso-apex; costa developed; sacculus absent. Juxta rectangular. Aedeagus with a denticle or a hook before apex ventrally.

Female genitalia (Figs 9-11). Papillae anales collar-shaped in basal half, shovel-shaped in distal half. Apophyses anteriores usually membranous distally, longer than apophyses posteriores. Antrum differing in shape. Corpus bursae ovate; signa two, with dense denticles.

Diagnosis: Epilepia is similar to TeliphasaMoore, 1888 in the forewing with both discal and discocellular spots represented by a tuft, and the postmedian line curved outward and forming an angle medially. Epilepia can be separated from Teliphasa by the hindwing without a discocellular spot, and in the male genitalia by the elongate uncus, the absence of a gnathos, and the sub-ovate valva. In Teliphasa, the hindwing bears a discocellular spot; and the semicircular uncus is undeveloped, the gnathos is present, and the valva is sub-rounded in the male genitalia.

Diagnosis: This new species is similar to E. longaduncata Rong & Li, sp. n. in both forewing pattern and male genitalia. It can be distinguished in the male genitalia by the valva with costa nearly straight dorsally, the juxta with length about 1.3 times the width, and the aedeagus with a denticle near apex ventrally; and in the female genitalia by the rectangular antrum. In E. longaduncata sp. n., the costa of the valva is convex beyond middle dorsally, the length of the juxta is about 0.8 times the width, and the aedeagus has a long hook near apex ventrally; and the antrum is torch-shaped in the female genitalia.

Description: Adult (Fig. 2) wingspan 25.0-30.0 mm. Head white. Male labial palpus slender; first segment white on basal half, black mixed with grayish green on distal half, about 1/4 length of second; second segment exceeding vertex apically, white mixed with blackish gray on basal half, blackish gray on distal half, ventral surface with short blackish gray mixed with yellowish fuscous hair-like scales on distal 1/4; third segment black on basal half, white on distal half, tapering, about 1/4 length of second; female labial palpus slightly shorter than male. Maxillary palpus compressed and short, white mixed with pale yellowish fuscous. Antenna black, with white annulations on dorsal surface; male with short grayish white cilia on ventral surface, cilia along outer side line about 1.2 times of diameter of antenna, inner side line about 2.0 times of diameter of antenna. Thorax and tegula blackish gray, mixed with dirty white and grayish green. Forewing basal area black with dense white scales on anterior 1/3, white with dense pale yellowish fuscous scales on posterior 2/3, with an arched semicircular strip at base; median area white, suffused with black and pale yellowish fuscous scales; distal area blackish gray, slightly paler near termen; antemedian line black, from middle of lower margin of cell slightly arched outward to basal 1/4 of dorsum; postmedian line black, wide, from beyond 2/3 of costal margin arched inward to M₃, then oblique inward to base of CuA₂, finally vertical to distal 1/3 of dorsum, beyond postmedian line at costal margin set a white mixed with black spot; discal and discocellular spots represented by a black tuft, with white scales bordering its outside; rectangular black patch placed along costal margin above discal spot; terminal line pale yellow, evenly spaced with uniform black rectangular spots along its inner side, interrupted with pale yellow on veins. Hindwing deep gray, darkening toward apex, with weak metal flash near costal margin; with a short oblique black strip from upper corner to lower corner of cell. Cilia of both wings pale yellow, interrupted with black on extension of veins. Legs with inner side white; outer side black, with dense white and grayish green scales on femora and tibiae, mid tibiae with black mixed with white and grayish green hairs, hind tibiae with white hairs, tarsi with each tarsomere white at apex. Abdomen with 3rd to 5th segments white mixed with black and yellow on ventral surface, remaining segments black mixed with yellow; black suffused with white on dorsal surface, 1st to 3rd segments white anteriorly.

Male genitalia (Fig. 6): Uncus with basal half uniformly narrow, distal half widened to apex, apex concave in triangle at middle; with dense fine hairs dorsally. Valva sub-ovate, narrowed basally, with dense fine hairs, with a sclerotized wavy fold from base reaching below dorso-apex; costa nearly straight dorsally, narrowed basally and distally, produced roundly and with dense setae ventro- medially. Juxta broad, sub-rectangular, with length about 1.3 times width, weakly sclerotized, with dense microtrichia posteriorly. Aedeagus slender, about 3/5 length of ventral margin of valva, its basal 1/3 membranous, distal 2/3 weakly sclerotized, with a denticle near apex ventrally; cornuti composed of a bunch of long spines, one of them slightly stronger and longer.

Female genitalia (Fig. 9): Papillae anales collar-shaped in basal half, shovel-shaped in distal half, with hairs of varying length. Eighth segment rectangular, with dense long setae posteriorly; sternite banded, triangularly produced at middle anteriorly. Apophyses anteriores about 1.3 times length of apophyses posteriores, slightly thicker, distal 1/4 membranous. Antrum rectangular. Ductus bursae thick, strongly sclerotized. Corpus bursae ovate, about 1.5 times length of ductus bursae; signa with dense denticles, smaller signum sub-rectangular, larger signum rounded.

Distribution: China (Guangxi, Guizhou).

Etymology: The specific name is derived from the Latin denticulatus, meaning denticulate, referring to the denticle near apex of the aedeagus.

Diagnosis: Adult (Fig. 5) wingspan 22.0-28.0 mm. This species can be distinguished from the above two new species by the long brush-like maxillary palpus in male and the forewing not white in the median area; in the male genitalia by the uncus widened distally, the juxta with a horsehead- shaped process, and the aedeagus without a hook or denticle near apex ventrally (Fig. 8); and in the female genitalia by the infundibulate antrum (Fig. 11).

Distribution: China (Fujian, Guangxi, Guizhou, Hainan, Hebei, Henan, Hubei, Hunan, Shanxi, Sichuan, Taiwan, Tianjin, Zhejiang); Japan, North Korea.

Discusion

Epilepia dentatum (Matsumura & Shibuya, 1927) was described from Japan, and was also found in China and Korea. The two new species described in this paper are closely associated with E. dentatum. However, we found the three species different from the African species in the external characters by the absence of the scape extension in male, and in the male genitalia by the absence of the gnathos and the valva lacking the process at base of the upper margin; in the African species, the scape extension and the gnathos are present, and the valva bears a process at base of the upper margin. We tentatively place these two species in the genus Epilepia, and their affiliation with the African species needs further study.

Acknowledgments

We express our cordial thanks to those who participated in the field collection and to Dr. D. D. Zhang (Guangzhou, China) for providing some specimens. This research was supported by the National Natural Science Foundation of China (No. 31672372).
