簡介
舟蛾科禾舟蛾亞科是一群大多成蟲體色黃色調而幼蟲主要取食禾本科的類群,由於這類群外觀大多相似但生殖器形態多樣,過往不同學者對其分類體系的屬級定義與屬級物種多樣性看法不一,其中對廣義的禾舟蛾屬(Bireta sensu lato)的觀點最不一致。
本研究為了釐清一台灣產禾舟蛾類新分類群的屬級地位與其近緣種關係,回顧廣義禾舟蛾屬在Schintlmeister (2008)歐亞大陸舟蛾科誌的形態特徵以及Kobayashi與Nonaka(2016)的舟蛾科分子親緣關係。本研究重新定義包含䓢舟蛾(Cutuza)與荻舟蛾(Dypna)枝系的共衍徵為拱狀的軛片(juxta),而此兩屬可由抱器(valva)不同的骨化突起部位作區分。
基於上述形態特徵評估,台灣產新分類群為一荻舟蛾屬之特有新種宇老荻舟蛾 D. yulaonensis Wu & Lai, 2018,其近緣種為由禾舟蛾屬轉置荻舟蛾屬之兩雲南產物種:D. sicarius (Schintlmeister, 2008)與D. parricidae (Schintlmeister, 2008)。
此外,另有以下新組合名處理:
Dypna rapinae (Schintlmeister, 2008) (Bireta) 新組合名
Dypna extortor (Schintlmeister, 2008) (Bireta) 新組合名
Dypna theodosius (Schintlmeister, 1997) (Torigea) 新組合名
Dypna theodosius felicitas (Schintlmeister, 2008) (Bireta) 新組合名
Dypna dorsisuffusa (Kiriakoff, 1962) (Bireta) 新組合名
Cutuza formosana (Nakamura, 1973) (Torigea) 新組合名,台灣特有種,新倡議俗名:台灣䓢舟蛾
最後,兩物種屬級則由禾舟蛾屬(Bireta)轉回原始描述屬級:
Torigea fortis Kobayashi & Kishida, 2008
Mangea gemina Kishida & Kobayashi, 2004 台灣特有種,建議俗名:雙星繁花舟蛾
Abstract
Abstract
A new notodontid species of the genus Dypna Kiriakoff, 1962, D. yulaonensis sp. nov. is described from Taiwan, with the taxonomic notes on some broad sense Bireta species in the tribe Ceirini of subfamily Spataliinae. The arciform juxta is regarded as the synapomorphic character of Cutuza and Dypna clade, the heterogeneous sclerotized projection of valva can be adopted to separate these two genera. Totally eight new recombinations are proposed, i.e. Dypna rapinae (Schintlmeister, 2008), comb. nov., D. sicarius (Schintlmeister, 2008), comb. nov., D. parricidae (Schintlmeister, 2008), comb. nov., D. extortor (Schintlmeister, 2008), comb. nov., D. theodosius (Schintlmeister, 1997), comb. nov., D. theodosius felicitas (Schintlmeister, 2008), comb. nov., D. dorsisuffusa (Kiriakoff, 1962), comb. nov., C. formosana (Nakamura, 1973), comb. nov. The species Torigea fortis Kobayashi & Kishida, 2008 and Mangea gemina Kishida & Kobayashi, 2004 are transferred back into their original genus, respectively, from Bireta sensu Schintlmeister, 2008 (comb. rev.).
