Reports of Drawida (Oligochaeta: Moniligastridae) from far East Asia

The Moniligastridae Claus, 1880 presumably arose in a region now occupied by the Malay Archipelago sufficiently long enough ago to have widely colonized and speciated in the Far East and to have radiated westwards even as the Himalayas formed to occupy the Indian subcontinent as far as Sri Lanka (Michaelsen, 1909; 1922; Gates, 1972). A less popular alternative is the family has “recent Indian origin” colonizing Asia after collision of the Indian Plate (Easton, 1981: 34), although most authors agree on a southern Indian homeland concentration for genus Drawida speciation. Along with holarctic Lumbricidae in the Northern Hemisphere, Acanthodrilidae in the Southern Ocean and Octochaetidae in Indo-Australasia, it is considered one of the most naturally widespread of earthworm families (Gates, 1972; Blakemore, 2013c). It currently has approximately 215 valid species in six genera (Csuzdi, 2012), mainly in South Asia and southeast Asia. The family diminishes further East, or rather its taxonomic study does; for example, Kobayashi (1940: 311) reporting on Manchurian worms listed less than a dozen East Asian species although these are still important in agricultural and ecological studies to this day. Only a few are peregrine cosmopolitans (Blakemore, 2012b), in particular Drawida barwelli (Beddard, 1893) is widely transported in the tropics, e.g. first Australasian moniligastrid report by Blakemore (1994), albeit many records of this small worm are likely mistaken as it was confused even in its earliest descriptions.

First record of the genus Neomegacoelum Yasunaga (Hemiptera: Heteroptera: Miridae) from the Korean Peninsula.

A monotypic genus, Neomegacoelum Yasunaga (Hemiptera: Heteroptera: Miridae: Mirinae), is reported from the Korean Peninsula for the first time with a species of Neomegacoelum vitreum (Kerzhner, 1988). The morphological information such as description and diagnoses are provided with the photographs of adult specimen and genitalia.

Account of montane and insular speciation in some Korean megadriles (Annelida: Oligochaeta)

In the spirit of Kobayashi (1936; 1937; 1938; 1941) and Easton (1981), the current work contributes to the first author’s current Japanese and Korean studies, e.g. Blakemore (2003; 2008; 2012a-f; 2013a; 2013b; 2014), and attempts to use genetic barcodes of primary types or neotypes for definitive species identity (Hebert et al., 2003; Blakemore, 2013c). Current specimens are from mountains such as Seoraksan (alt. 1,708 m) the highest mountain in the 500 km Taebaek Range that edges the east coast as far down as Busan and the third highest after Hallasan and Jirisan in the south. Further collection was at nearby Bangtaesan (alt. 1,444 m) and Jeombongsan (alt. 1,424 m). Islands were also sampled, and the briefest of surveys on the isle of Muuido near Incheon unearthed two new species: a megascolecid Amynthas muuido sp. nov. and a lumbricid Eisenia muuido sp. nov., the latter comparable to endemic Eisenia koreana (Zicsi, 1972) that was surprisingly overlooked in Hong’s (2000) incomplete review of Korean Lumbricidae (compare his nine or ten spp. to the twenty listed in Blakemore, 2014). The current paper complements an update of moniligastrid Drawida spp. in Blakemore et al. (2014).

First description of the last instar larva and pupa of the aquatic crane fly Limnorimarga limonioides (Alexander, 1945) (Diptera: Limoniidae)

Descriptions, illustrations and habitat characteristics are given for the previously unknown larvae and pupae of the East Palaearctic monotypic aquatic crane fly genus Limnorimarga Alexander, 1945 collected from Korea in hygropetric habitats. Diagnostic features and phylogenetic relationships are discussed.

The Subgenus Exosyntretus Belokobylskij of the Genus Syntretus (Hymenoptera: Braconidae: Euphorinae) from Korea

Two species of the subgenus Exosyntretus (Hymenoptera: Braconidae: Euphorinae) in the genus Syntretus are reported from Korea in this study. Among them, Syntretus (Exosyntretus) nevelskoii Belokobylskij is new to Korea. The world checklist, diagnosis and distribution data are included.

Notes on the Genus Cosmophorus Ratzeburg (Hymenoptera: Braconidae: Euphorinae) from Korea

Two species of the genus Cosmophorus (Hymenoptera: Braconidae) are reported in this study. Among them, Cosmophorus (Cosmophorus) klugii Ratzeburg is new to Korea. Diagnosis and distribution data are included.

Notes on the Genus Asiacentistes Belokobylskij (Hymenoptera: Braconidae: Euphorinae) from Korea

Two species of the genus Asiacentistes (Hymenoptera: Braconidae) are reported in this study. One of them, Asiacentistes sinica Chen and Belokobylskij is new to Korea. Diagnosis and distribution data in East Asia are included.

Two new records of the genus Arboridia Zachvatkin (Hemiptera: Auchenorrhyncha: Cicadellidae: Typhlocybinae) from Korea.

Two newly recorded species of the genus Arboridia Zachvatkin (Hemiptera: Auchenorrhyncha: Cicadellidae: Typhlocybinae) from Korea are reported, which are Arboridia lunula Song & Li, 2013 and Arboridia agrillacea (Anufriev, 1969). Photographs of dorsal habitus, illustrations of male genitalia, abdomens and forewings and distributional records are provided. In addition, a key to the Korean Arboridia species is also given.

Two new Korean earthworms (Annelida, Oligochaeta, Megadrilacea, Megascolecidae).

Abstract Two Korean endemic pheretimoid Amynthas Kinberg, 1867 species belonging in family Megascolecidae s. stricto are sketched, dissected and described. Amynthas daeari Blakemore sp. n. has spermathecae in 6/7/8 complying with an Amynthas tokioensis spp-group, whilst Amynthas jinburi Blakemore sp. n. has spermathecal pores in 5 & 6 strictly complying with Sims and Easton’s (1972) Amynthas canaliculatus-group. A definitive COI gene barcode is provided for the holotype of Amynthas daeari but the age since collection or preservation of the Amynthas jinburi type in 2000 precluded its mtDNA extraction at this time.
