Taxonomy of the Cidariini (Lepidoptera, Geometridae) in Korea (I)

ABSTRACT Among forty species of the Korean Cidariini, a tribe of Larentiinae (Lepidoptera, Geometridae), nineteen species of ten genera are revised: Ecliptopera Warren, Lampropteryx Stephens, Eustroma Hübner, Eveeliptopera Inoue, Lobogonodes Bastelberger, Hysterura Warren, Sibatania Inoue, Eulithis Hiibner, Gandaritis Moore, and Electrophaes Prout. The diagnostic characters and monophyly of each genus are provided. Figures of adults including male and female genitalia, and distribution maps in Korea are also provided.     

Cladistic biogeography of the moth tribe Cidariini (Lepidoptera, Geometridae) in the Holarctic and Indo-Chinese regions

A cladistic biogeographic analysis for the Holarctic and Indo-Chinese regions was undertaken based on seven genera of the tribe Cidariini: Cidaria Treitschke, Thera Stephens, Pennithera Viidalepp, Heterothera Inoue, Callabraxas Butler, Gandaritis Moore and Eulithis Httbner. Smallest coincident ranges of two species recognized 11 endemic areas. The study has two aims: to construct a hierarchical structure of those areas, and to recognize dispersal events. Under two assumptions [widespread taxa mapped (identical as assumption 0) and widespread taxa not mapped (identical as assumption 1)] the 11 endemic areas were mapped with 72 taxa. The best resolved area cladograms under the two assumptions differ in the placement of one endemic area, northern Europe. Area relationships found in this present analysis are congruent with the current landmass configurations: (North America, (Europe, (northern India, (southwestern Asia, (Baikal area, (south China, (Taiwan, (Russian Far East, Japan)))))))). These area cladograms postulate at least three vicariance events: (1) between North America and the Palaearctic; (2) western-eastern Palaearctic; (3) northern India–the rest of Asia. The approach to recognize dispersed taxa by pruning each taxon suggests that most dispersal events occurred in East Asia: from the Baikal area or south China to the Russian Far East; and from the Russian Far East to Japan. Relationships among endemic areas are briefly discussed.     

Conservation of Hipparchia autonoe (Esper) (Lepidoptera: Nymphalidae), Natural Monument in South Korea

Hipparchia autonoe, designated Natural Monument no. 458, is a species inhabiting Mt. Halla on Jeju Island, which is the only habitat of H. autonoe in South Korea. Recently, this species is in danger of extinction as the population has been remarkably reduced because its host plants and nectar plants are gradually disappearing due to plant succession in its habitat. On the climbing road of Jeju Island Eorimok, H. autonoe used to be observed at and above 1300 m a.s.l. However, since Sasa quelpaertensis has recently expanded its habitat up to 1400 m, H. autonoe is now observed at and above 1500 m. In Mongolia, the population of H. autonoe seems quite stable as there are dense populations of a host plant and nectar plants. Accordingly it is judged that we can maintain a stable community for support of H. autonoe if we successfully manage the host plant and nectar plant communities by controlling the density of S. quelpaertensis using biological and physical control methods. Comparative analysis of DNA barcode region of COI (658 bp) was done to check the homogeneity and the genetic diversity of H. autonoe collected in Korea and Mongolia. The DNA sequence difference among individuals collected in South Korea was 0.0–0.2%, and in Mongolia 0.0–1.4%. This confirmed a 0.06–1.2% barcoding gap. We believe that this result will provide basic information useful to guide conservation of H. autonoe in South Korea.     

澳门翼手类物种多样性调查

2009 ～2012 年,对澳门翼手目(蝙蝠)物种多样性进行了调查。结果共捕捉到10 个物种,属5 科8 属,其中包括澳门原来记载的2 个物种,即蹄蝠科的大蹄蝠(Hipposideros armiger)和蝙蝠科的东亚伏翼(Pipistrellus abramus);本研究新增加8 个物种,即狐蝠科的犬蝠(Cynopterus sphinx) 和棕果蝠(Rousettus leschenaulti),鞘尾蝠科的黑髯墓蝠(Taphozous melanopogon),菊头蝠科的菲菊头蝠(Rhinolophus pusillus),以及蝙蝠科的大足鼠耳蝠(Myotis ricketti)、普通伏翼(P. pipistrellus)、普通长翼蝠(Miniopterus schreibersi) 和南长翼蝠(M. pusillus)。另外,通过野外录音和分析,并与已发表物种声音特征比较核对,发现菊头蝠科和蹄蝠科各一种,前者可能是泰国菊头蝠(R. siamensis)或者中菊头蝠(R. affinis),后者可能是果树蹄蝠(H. pomona) 或者三叶蹄蝠(Aselliscus stoliczkanus)。本文对已捕捉10 种蝙蝠的分布、形态特征和回声定位叫声特征进行报道,同时对其种群数量和保护现状进行了讨论。保护蝙蝠栖息生境(洞穴、古老建筑和蒲葵树等) 对保护澳门蝙蝠物种多样性至关重要。     

Systematics of the genus Cidaria Treitschke (Lepidoptera, Geometridae, Larentiinae)

The genus Cidaria Treitschke is revised. Eight species of the genus which occur widely in the Palaearctic and northern India, are recognized, of which one, Cidaria luteata sp. nov. , is described as new while two subspecies of C. fulvata (Forster) are elevated to species, C. nugata Felder stat. rev., and C. distinctata Staudinger stat. nov. C. ochripennis Prout is proposed as a junior synonym of C. ochreata Staudinger. C. deletaria Hampson is excluded from the genus. All species of Cidaria and their genitalia are described and illustrated. The cladistic analysis of these eight species of Cidaria is carried out using two data matrices, the first comprising morphological characters alone and the second morphological and distributional characters. The most parsimonious cladogram of Cidaria is selected, and its monophyly defined. The character analysis shows that some distribution characters contribute to resolving the in group node. The choice of multiple trees is discussed.     

Ecological and morphological characteristics of endoparasitoids on Elcysma westwoodii (Vollenhoven) (Lepidoptera: Zygaenidae)

Six species of insect endoparasitoids were identified from Elcysma westwoodii, which is the most damaging lepidopteran pest of Prunus yedoensis. From Hymenoptera, two species were identified: a species in Braconidae and Charops striatus in Ichneumonidae. From Diptera, there were four species in Tachinidae: Compsilura concinnata, Exorista sp., Pales sp. and Tachinidae spp. The parasitic ratio was 4.86% (45 of 926 larvae). The hymenopterans were parasitic on 31 individuals of E. westwoodii (68.9%) and the dipterans were parasitic on 14 individuals (31.1%). It was found that parasitoids from the larvae of E. westwoodii were all either endoparasitoids or larval parasitoids. However, Exorista sp. of Tachinidae was found to be either a larval parasitoid or larval-pupal parasitoid. Additionally, all the identified parasitoids were solitary parasitoids, as only one parasite occurred in a larva of E. westwoodii. Because the larva of E. westwoodii eats and molts after it is parasitized, all the parasitoids were identified as koinobionts. There were no big differences in morphological characteristics and life histories between C. striatus and C. concinnata. However, for Exorista sp. and Pales sp., males took 3–5 days longer to emerge from their pupae and had remarkably longer body lengths than females.

Two middle Cambrian diceratocephalid trilobites, Cyclolorenzella convexa and Diceratocephalus cornutus, from Korea: development and functional morphology

Park, T.-Y. & Choi, D.K. 2010: Two middle Cambrian diceratocephalid trilobites, Cyclolorenzella convexa and Diceratocephalus cornutus , from Korea: development and functional morphology. Lethaia , Vol. 43, pp. 73–87.
Silicified sclerites of the latest middle Cambrian trilobites, Cyclolorenzella convexa and Diceratocephalus cornutus , have been recovered from the Sesong Formation, Korea. Their morphological similarity and stratigraphic occurrences suggest that D. cornutus is a descendant of C. convexa . The ontogenies of both trilobites demonstrate that a pair of long frontal horns in the cephalon of D. cornutus is an evolutionarily novel structure. It is inferred that redeployment of some pre-existing regulatory gene played a significant role in constructing the frontal horns of D. cornutus . The frontal horns may have been a defensive structure to deter predators. The facial suture of D. cornutus , which extends onto the frontal horns and splits them into the dorsal and ventral halves, was a solution to enable easier forward egression during ecdysis. □ Functional morphology, Korea, Middle Cambrian, ontogeny, trilobites .
