Promalactis established by Meyrick in 1908, is one of the highest species richness genera of the family Oecophoridae. Over 240 described species are mainly distributed from Oriental and Palaearctic regions. They are usually a tiny-sized and exhibit subtle morphological differences which make problems on morphological-based identification. In this study, we performed DNA barcoding study for the Promalactis by using mitochondrial cytochrome c oxidase subunit I (COI). From analyzing 155 COI sequences, we observed the usefulness of the COI in species identification with intraspecific genetic variation (range 0.0-2.1%) and interspecific genetic divergence (range 2.8-15.4%).
The genus Promalctis Meyrick, 1908 is the largest genus of the family Oecophoridae, with more than 150 described species in the world (Wang et al., 2009; Du et al., 2009). The genus is mainly distributed in the Palaearctic and Oriental regions, probably with the highest diversity in the South and East Asia. However it has been very poorly studied to date, with only with only 4 publications which were based on very limited collecting. In total, 76 were reported from China, which is more than half of the known species in the Palaearctic region(Wang, 2006; Du et al., 2009), 14 species known from Korea (Park & Park, 1998), 12 species from Japan (Fujusawa, 2002), 8 species from Russian Far East (Lvovsky, 1976, 1985, 1986), and 3 species from Nepal (Lvovsky, 2000a). In the Oriental region, since Meyrick (1908a, 1908b) described 14 species from India and Myanmar, Lvovsky (2000a, 2000b) described 25 additional species from the southern Asia, including the southern part of China, Malaysia, Indonesia, and the Philippines. In Vietnam, only 4 species, Promalactis albiapicalis Lvovsky 1997, P. buonluoi Lvovsky 1997, P. fansipanella Lvovsky 2007, and P. suzukiella (Matsumura 1931), have been described to date(Lvovsky, 1997, 2007a). The aim of this study is to describe six new species of Promalactis based on material mainly collected in the northern part of Vietnam. Adults, head parts, wing venations, and the male or female genitalia of the new species are illustrated.
원뿔나방과(Oecophoridae)의 Promalactis속에 속하는 종들은 주로 인도지나 반도를 중심으로 하는 동양구에 분포하는 것으로 현재까지 외국에서도 이 속에 대한 분류학적 정리가 이루어진 바가 없다. 금번 필자는 우리나라산에 대한 정리를 위하여 일본의 북해도대학에 보관중인 일부 모식표본(Type Specimen)들의 생식기 스라이드를 송부받아 우리나라산과 비교검토할 기회를 얻었었다. 그 결과 필자에 의해 이미 신종으로 발표된 1종에 이어 2종을 추가로 분류동정하여 우리나라 미기록종으로 발표한다.
신종 Promalactis odaiensis n. sp.(솔피원뿔나방 : 신칭)의 기재. Promalactis속은 주로 동양구에 분포하고 있으며 우리나라에서는 현재까지 보고된 종이 없다. 그러나 최근 필자의 조사로 5~6종이 확인되었으며 그 1종을 신종으로 우선 발표한다. 또한 Ocecophoridae 한국동물명집, 곤충편에 원무늬잎말이 나방으로 되어있으나, 뿔나방상과(Gelechioidea)에 속함으로 원뿔나방과로 개칭한다.
