### Introduction

The genus Lecithocera Herrich-Schäffer, 1853 is the most diverse genus of the family Lecithoceridae, comprising more than 300 species described in the world. Of these, 49 species have been described by the author and his co-authors since 1998 (PARK, 2012b; 2014). The genus is highly diverse all over the world, except in the Neotropical Region. Little has been published on the larval feeding habits of the family. Some Australian species feed on Eucalyptusleaf litter (COMMON, 1996) and Lecithocera thiodora (Meyrick, 1914) was reared from dead leaves of broad leaved trees in Japan (KOMAI et al., 2011).

For the genus Lecithocera occurring in the Philippines, MEYRICK (1910, 1916, 1923, 1929) described six species: L. cassiterota Meyrick, 1923, L. megalopisMeyrick, 1916, L. faustaMeyrick, 1910, L. ochrocapnaMeyrick, 1923, L. recurvataMeyrick, 1923, and L. goniometra Meyrick, 1929. Among them, L. cassiterota was previously transferred to Chrysonasma PARK (2008a), and L. ochrocapnaand L. recurvatato Torodora by PARK (2008b). DIAKONOFF (1967) described 12 species of Lecithocera, but three of them (L. activate Diakonoff, 1967, L. niphotricha Diakonoff, 1967, and L. phanerostoma Diakonoff, 1967) were also transferred to Torodora Meyrick, 1894 by PARK (2008b). PARK (2008b) suggested that a further three species (L. acribostola Diakonoff, 1967, L. decorosa Diakonoff, 1967 and L. strenua Diakonoff, 1967) described by DIAKONOFF (1967) should be considered for transfer from Lecithocera to other genera, due to the different shape of the forewings with sharply produced apex (in L. acribostolaand L. decorosa ) and differing male genital character (in L. strenua). The other two species, L. sophronopa Diakonoff, 1967 and L. telospermaDiakonoff, 1967 are retained in the genus, with some uncertainties because of different venation and wing pattern. These five species are not included in this review

Consequently, seven species, L. fausta Meyrick, 1910, L. goniometra Meyrick, 1929, L. megalopis Meyrick, 1916, L. docilis Diakonoff, 1967, L. luteola Diakonoff, 1967, L. leucomastis Diakonoff, 1967, and L. improvisa Diakonoff, 1967 are known so far as members of the genus in the Philippines, and seven additional species of the genus are described in this paper as new to science. However, the number of species occurring in the Philippines seems to be much larger and we are still far from having a thorough knowledge of the real dimension of the fauna living in this archipelago.

### Materials and methods

Specimens examined in this study are the material loaned from the Museum für Naturkunde, Humboldt-Universität, Berlin (MfN), collected by W. Mey and his colleagues in Luzon, Samar and Leyte in 1995, 1997 and 2001. For seven new species, full descriptions of external and genital characters with diagnosis, distribution, and remarks are given. Also, diagnoses and the re-description of male genitalia are provided for a newly reported species from the Philippines. For the four previously known species found in this study, general taxonomic information including bibliographies, the type locality (TL), diagnosis, sources of figures of genitalia, distribution, and remarks, are communicated. The other three species, which are not dealt with in this study, are only listed. The preparation of genitalia slides followed standards described in PARK (2012a) and the colour standard for the description of adults followed KOENERUP & WANSCHER (1978). Types of the new species are preserved in the Museum für Naturkunde Humboldt-Universität, Berlin (MfN), Germany.

#### Newly recorded species from the Philippines

Lecithocera castanoma Wu, 1997 (Figures 8, 17, 17a)

Lecithocera castanoma Wu, 1997: 125. TL: Guangdong, S. China.

Diagnosis: Wingspan, 12.0 mm. The new species is superficially similar to the preceding new species, L. leytensis sp. n., but it is distinguished by the forewing clothed with browner scales, without a dark brown marginal line along termen and the cucullus of the male genitalia is broader, with costal margin convex medially.

Male genitalia (Figs. 16, 16a-b): See also also WU (1997, pl. 10, fig. 4). Similar to those of L. nepalica Gozmány, 1973 but can be distinguished from the latter by having longer cucullus with the dorsal margin of valva convex medially and round anterior margin of saccus.

The species is similar to L. luteola Diakonoff, 1967 but can be distinguished by the larger size, a transverse dark-brown suffusion between the second stigma and the hind margin, the absent plical stigma, and six dark dots along the termen. Judging from the male genitalia, this species belongs to the L. pelomorpha species group, with broad, short cucullus with a rounded caudal margin, but differ from them by having a less angulated costal bar.

Male genitalia: DIAKONOFF (1967, Figs. 168-169, 197-198, 617).

Material examined: 2 11, Luzon, Mountain Province, Barlig, 1650 m, 14~15-XI-1997, coll. Mey,

Ebert, Nuss, gen. slide no. CIS-6237/Park, -6259/Park.

Distribution: Philippines (Luzon).

Lecithocera goniometra Meyrick, 1929

Lecithocera goniometra Meyrick, 1910: 522; Clarke, 1965(5): 132; Diakonoff, 1967: 140. TL: Los Banos, Philippines.

Diagnosis: Wingspan, 15 mm. Similar to the preceding species with distinct discal stigmata and plical blackish dot, but the series of blackish dots on margin towards apex and along termen is not developed or is very weak, whereas in L. fausta the blackish dots are well presented.

Male genitalia: See Clarke (1965, Pl. 66, Figures 4, 4a-b); Diakonoff (1967, Figures 170-171, 192,

614).

Material examined: 1 1, Luzon, Mt. Banahaw, Kinabuhayan, 17~19-III-2000, coll. Mey & Richter, gen. slide no. CIS-6202/Park.

Distribution: Philippines (Luzon).

Lecithocera luteola Diakonoff, 1967

Lecithocera luteola Diakonoff, 1967: 145. TL: Luzon, Philippines.

Diagnosis: Wingspan, 11mm. This species can be distinguished by the smaller size, with smaller first discal stigma and the plical dot present beneath the second discal stigma; also by the male genitalia with narrowed, elongated cucullus.

Male genitalia: See DIAKONOFF (1967, Figures 184, 185).

Material examined: 1 1, Panay, Antique, Culasi San Vicente, 11-IV-1995, coll. Mey, gen. slide no. CIS-5289/Park; 2 11, Panay, Iloilo San Bernadino, 400 m, 12-IV-1995, coll. Mey, gen. slide no. CIS- 6235/Park.

Distribution: Philippines (Luzon).

Remarks: This species was described based on a single male.

Lecithocera docilis Diakonoff, 1967

Lecithocera docilis Diakonoff, 1967: 144. TL: Mt. Makiling, Luzon, Phillippines.

Diagnosis: Wingspan, 14 mm. The species is similar to L. fausta Meyrick, but the second discal stigma is smaller, the dark brown suffusion between the second stigma and the hind margin is absent, and dark dots along the termen are also absent. The male genitalia are similar to those of L. luteola Diakonoff, but the cucullus is broader and strongly upturned.

Male genitalia: See DIAKONOFF (1967, Figures 172, 173).

Material examined: 1 1, Luzon, Santa Fe, Bold Mt. 1,150 m, 11~13-XI-1997, coll. Mey & Ebert, Nuss, gen. prep. no. CIS-5034/Park.

Distribution: Philippines (Luzon).

#### Species not treated in this study

Lecithocera megalopis Meyrick, 1916

Lecithocera megalopis Meyrick, 1916: 575; Meyrick, 1925: 239; Diakonoff, 1967: 138, Fig. 608. TL: Luzon, Philippines.

This species is characterized by large blackish stigmata on the forewing and can be distinguished from the newly described species by these larger stigmata. Diakonoff (1967) examined a female specimen (abdomen missing) deposited in the Natural History Museum, London, and provided a photo of the type

Lecithocera improvisa Diakonoff, 1967

Lecithocera improbisa Diakonoff, 1967: 146, Fig. 620. TL: Mindanao, Philippines.

This species can be distinguished from L. luteolaDiakonoff, and L. docilis Diakonoff by the presence of a large, blackish plical dot before the first discal stigma and by the sharply produced apex of the hindwing.

Lecithocera leucomastis Diakonoff, 1967

Lecithocera leucomantis Diakonoff, 1967: 145, Fig. 160. TL: Luzon, Philippines.

This species can be distinguished from all newly described species in this study by the dark fuscous forewing ground color. The species is known from the female holotype only.
