文獻出處:Sohn, J. C. & H. R. Tzuoo. 2012. Two new species of Stenoloba (Lepidoptera: Noctuidae) from East Asia with the first description of S. nora female genitalia. Journal of Asia-Pacific Entomology 15: 241–244.

簡介

本文由美國馬里蘭大學昆蟲系的
Jae-Cheon Sohn描述兩種苔蘚夜蛾亞科Stenoloba屬新種S. ronkayi Sohn & Tzuoo (台灣)以及S. hystrix Sohn (越南北部),前者與現任職於南投埔里國小的左漢榮老師共同發表,新種模式產地為南投紅香,種小名以匈牙利自然史博物館Dr. Laszlo Ronkay的姓氏命之。此外本文首次描述S. nora之雌蟲形態。

Abstract

Two new species of Stenoloba Staudinger, 1892 are described: S. ronkayi Sohn and Tzuoo sp. nov. from Taiwan and S. hystrix Sohn sp. nov. from northern Vietnam. The relationships of the new species with the actual species groups of Stenoloba are discussed. The formerly unknown female of S. nora Kononenko and Ronkay, 2001 and its genitalia are described here for the first time.

Abstract
Adults of the Euthalia phemius complex, which is composed of three South-East Asian nymphalid species, Euthalia phemius, Euthalia ipona, and Euthalia euphemia, were genetically analysed by examining mitochondrial and nuclear genes. The E. phemius complex was also examined morphologically, with particular emphasis on wing markings and male genitalia. No significant differences amongst the three species in the complex were detected with respect to either genetic distance or genital morphology. We therefore conclude that the three currently recognized Euthalia species belong to a single species. Accordingly, E. ipona is synonymized with E. phemius. Euthalia euphemia is treated as a subspecies of E. phemius. Type specimens of all taxa and a synonymic list for the E. phemius complex are also given. In addition, we briefly discuss the evolution and biogeography of the species complex.
