Abstract

Orneodes zonodactyla var. eumorphodactyla Caradja, 1920 is regarded as a valid species with the following combination: Pterotopteryx eumorphodactyla (Caradja, 1920), comb.nov. Alucita sakhalinica Zagulajev, 1995 and Pterotopteryx koreana Bong-Kyu Byun, 2006, are synonymized with Pterotopteryx eumorphodactyla (Caradja, 1920). New data on the distribution of P. eumorphodactyla and Alucita ussurica Ustjuzhanin, 1999 in the Russian Far East are given.

Introduction

The Alucitidae comprise 216 species in 9 genera distributed around the world (van Nieukerken et al. 2011). The first Russian Far East representative of Alucitidae was described by Prince Aristide Caradja from the neighborhood of Radde Village as Orneodes zonodactyla var. eumorphodactyla Caradja, 1920. It was given species status as Alucita eumorphodactyla (Caradja, 1920) by Gielis (2003). The species was not listed in the Alucitidae chapter of the “Key to the Insects of the Russian Far East” (Ustjuzhanin 1999b), but it was included as Alucita eumorphodactyla in the “Catalogue of the Lepidoptera of Russia” (Ustjuzhanin and Kovtunovich 2008).

Pterotopteryx sakhalinica (Zagulajev, 1995) was described from the southern part of Sakhalin Island based on a series of 10 specimens (Zagulajev 1995). Later, we found that this species had a rather wide range, occurring not only on Sakhalin, but also in the southern Kurile Islands and the continental part of the Russian Far East, from Khasan District in the south to Nikolayevsk-on-Amur in the north (Ustjuzhanin and Kovtunovich 2008). More recently, Ustjuzhanin (1999a) described Alucita ussurica Ustjuzhanin, 1999 from the southern part of Primorsky Krai, currently its only known locality.

Five species of Alucitidae were reported from Japan (Hashimoto 1984). Two of them, Alucita japonica (Matsumura, 1931) and Pterotopteryx spilodesma (Meyrick, 1907), inhabit Hokkaido Island, the nearest territory to the Russian Far East. Both can be easily distinguished from Alucita ussurica and Pterotopteryx eumorphodactyla based on external characters and genitalia morphology. Three species have been recorded from Korea (Byun 2006): Alucita japonica, Pterotopteryx spilodesma, and the newly described Pterotopteryx koreana Byun, 2006.

Our re-examination of type specimens and study of additional material allow us to make some corrections and additions to the taxonomy and distribution of the Alucitidae species found in the Russian Far East.

Life history

Biology unknown. Flight period: V–VII. Probably develops in two generations.

Remarks

The type series of Orneodes zonodactyla var. eumorphodactyla Caradja, 1920 consists of six specimens held in MGAB. Dr. Mihai Stănescu, Lepidoptera collection manager in this museum, kindly sent us the abdomens of two paralectotypes for genitalia dissection. Our study of the male genitalia as well as external morphology revealed a number of diagnostic characters for the genus Pterotopteryx Hannemann, 1959 (third segment of labial palpus short, less than 1/3 as long as second segment; all five forewing R veins developed; valva with broad base; uncus undivided apically; gnathos acute apically; phallus nearly straight with spiniform cornuti in vesica) which provide ample reason for treating this taxon as a valid species within Pterotopteryx. In addition, all characters studied revealed the obvious conspecificity of Pterotopteryx eumorphodactyla with the recently described Alucita sakhalinica Zagulajev, 1995 (Zagulajev 1995: 111–115, figs 4–5) and Pterotopteryx koreana Byun, 2006 (Byun 2006: 42, figs 6–9). In particular, the following character states are diagnostic. The wings are yellowish ashy, the middle and outer bands are well defined, and there are several contrasting spots on the costal margin of the forewing, near the base. In the male genitalia, the uncus is laterally narrow and its apex is lanceolate in frontal aspect, the valvae are wide and sclerotized near the base, narrow and membranous to the apex, and the phallus is slightly curved and with well-developed cornuti. In the female genitalia, the antrum is cup-shaped, the bursa copulatrix is oval with a rounded signum, and the ductus is covered with small spines.

Remarks

This species, previously known only from its type locality, is actually more widely distributed in the region. In conclusion, only two species of many-plumed moths are known in the south of the Russian Far East: Pterotopteryx eumorphodactyla and Alucita ussurica.
