Abstract Two new species of ryocalanoid copepods (Crustacea: Calanoida), Ryocalanus squamatus sp. nov. and Yrocalanus kurilensis sp. nov. are described together with a female of Ryocalanus infelix Tanaka, 1956, type species for the genus Ryocalanus Tanaka, 1956, from abyssal depths in the Kurile-Kamchatka trench. The new species can be assigned to the superfamily Ryocalanoidea based on the segmentation and armature of the swimming legs and the modification of the male right antennule. A new interpretation of the fusions of segments in the male right antennule of Ryocalanus shows the marked differences between the ryocalanoidean genera. The status of Ryocalanoidea within the Calanoida is discussed based on morphology and a first molecular multi-gene analysis with cytochrome oxidase subunit I, cytochrome b, nuclear ribosomal 18S and 28S rDNA and internal transcribed spacer 2. This analysis supports the close interrelationship between Ryocalanoidea and Spinocalanoidea. The monophyletic status of Ryocalanoidea could not be retrieved in the phylogenetic analysis, as specimens of Yrocalanus formed a clade within Spinocalanoidea. The inconclusive results between morphological and molecular analyses are discussed with a proposition to keep the current system until more males of taxa belonging to the Spinocalanoidea are discovered, as the male antennule plays a crucial role in the interpretation of relationships between Ryocalanoidea and Spinocalanoidea.

First Time

A taxonomic revision of the tribe Ceroptresini (Hymenoptera: Cynipidae) is conducted for the first time. Prior to this study, the total number of valid species of Ceroptres, the only genus within Ceroptresini to date, was 23. As a result of this revision, 15 Ceroptres species are retained as valid and one species, Amblynotus ensiger Walsh, 1864, is desynonymized from Ceroptres petiolicola (Osten-Sacken, 1861), being considered here as a valid Ceroptres species: C. ensiger (Walsh, 1864) status verified and comb. nov. An additional five new species are described from Mexico: Ceroptres junquerasi Lobato-Vila & Pujade-Villar sp. nov.; C. lenis Lobato-Vila & Pujade-Villar sp. nov.; C. mexicanus Lobato-Vila & Pujade-Villar sp. nov.; C. nigricrus Lobato-Vila & Pujade-Villar sp. nov.; C. quadratifacies Lobato-Vila & Pujade-Villar sp. nov., increasing the total number of valid Ceroptres species to 21. Ceroptres masudai Abe, 1997 is synonymized with C. kovalevi Belizin, 1973. Ceroptres niger Fullaway, 1911 is transferred to Andricus (Andricus confusus Lobato-Vila & Pujade-Villar comb. nov. and nom. nov.). Five species (Amblynotus inermis Walsh, 1864; Cynips quercusarbos Fitch, 1859; Cynips querficus Fitch, 1859; Cynips quercuspisum Fitch, 1859; and Cynips quercustuber Fitch, 1859) are not considered as valid Ceroptres. The status of Ceroptres quereicola (Shinji, 1938), previously classified as an unplaced species, is commented on. In addition, a Nearctic species from the USA, Ceroptres politus Ashmead, 1896, is here proposed as the type species of a new genus within Ceroptresini: Buffingtonella Lobato-Vila & Pujade-Villar gen. nov. Redescriptions, biological and distribution data, illustrations and keys to genera and species within Ceroptresini are provided. The diagnostic morphological traits of Ceroptresini, Ceroptres and the new genus are discussed.

The Oriental Pantheinae genus Donda Moore, 1882 is revised. The type-species of the genus—Donda eurychlora (Walker, 1858) is recognized as a complex of species. Two new species, Donda continentalis sp. n. from Thailand, China, and Vietnam and D. sundana sp. n. from Indonesia are described. Two species, D. thoracica Moore, 1882 and D. striatovirens Moore, 1883, are excluded from the genus Donda. The status of two taxa, D. ornata Moore, 1883 and D. lichenoides (Hampson, 1894) remains open. The imagines, male and female genitalia are illustrated. The checklist of the genus Donda is presented.

A new potamiscine genus, Laevimon, is established for two species of semi-terrestrial freshwater crabs from Vietnam, viz., Laevimon kottelati, new species (type species) and L. tankiensis (Dang & Tran, 1992). The genus is morphologically closest to Hainanpotamon Dai, 1995, but is easily distinguished by distinct sternal and gonopodal characters. The status of Orientalia Dang, 1975, a synonym of Hainanpotamon, as a junior homonym of Orientalia Radoman, 1972 (Mollusca), is also discussed.

AbstractA new species of Skrjabinolecithum (Digenea: Waretrematinae), Skrjabinolecithum pyriforme n. sp., has been found in the intestines of Liza haematocheila and Mugil cephalus from the Primorsky Region, Russia. These worms differ from S. vitellosum and S. lobolecithum by the presence of two caeca, as do S. spasskii, S. indicum and S. bengalensis. These species differ morphologically from S. pyriforme n. sp. by a number of features, including body width, oral sucker, pharynx, eggs and ratio of length and width of the body. The most similar species to S. pyriforme n. sp. is Platydidymus flecterotestis (Zhukov, 1971) with some differences in maximal body length, testis and egg sizes. The results of molecular analysis confirmed that this new species belongs to Skrjabinolecithum on the basis of close relationships with S. spasskii-type species.

AbstractThe species of the genus Spathiostenus Belokobylskij, 1992 are revised and illustrated. A redescription of the type species Eucorystes formosanus Watanabe, 1934 is given. Two new species are described: S. brevicauda sp. nov. from New Guinea and S. pasohus sp. nov. from Malaysia and Brunei. A new synonym (Eucorystes formosanus Watanabe, 1934 = Eucorystes tenuis Nixon, 1943, syn. nov.) and a new combination [Polystenus anacolus (Chen & Shi, 2004), comb. n.] are suggested. The transformation of the first tergite into the petiole in Doryctinae and the status of the genus Spathiostenus are discussed.

A New Species

Miltochrista Hübner, [1819] is a large genus of lichen-moths (family Erebidae, subfamily Arctiinae, tribe Lithosiini) including more than 160 valid species and widely distributed in Oriental and Palaearctic Regions. The genus for a long time was treated in a wide sense. Holloway (2001) treated as Miltochrista only a small group of species close to the type species of the genus Miltochrista miniata (Forster, 1771), resurrected genera Barsine Walker, 1854, and Lyclene Moore, [1860], and transferred the majority of former Miltochrista and Oriental Asura Walker, 1854 to these genera. Following Holloway's concept, many species were described as Lyclene during last two decades (Černý & Pinratana 2009; Kirti & Gill 2009; Bucsek 2012; 2014; Dubatolov & Bucsek 2013; 2014; Wu et al. 2013; Černý 2016). Kirti & Singh (2016) synonymized Lyclene with Miltochrista, but, nevertheless, the status of Lyclene is still debatable, and the generic/subgeneric structure of Miltochrista sensu lato needs revision (Volynkin et al., in prep.).

A New Species

A new species belonging to Lactarius subg. Plinthogalus was discovered during a long-term project on the diversity of Korean Lactarius. This species is proposed here as Lactarius cucurbitoides. The status of L. cucurbitoides as a new species is supported by molecular data and morphological features. Phylogenetic analysis based on internal transcribed spacer (ITS) sequences shows that L. cucurbitoides is closely related to L. subplinthogalus, L. friabilis, and L. oomsisiensis, with pairwise distances of 2.8–4.3%. Morphological characters of L. cucurbitoides that distinguish it from these closely related species are a pale yellow to pale orange colored pileus and non-discoloration of white latex. The new species is described and illustrated in the present paper.

Lecanora parasymmicta Lee & Hur and Protoparmeliopsis crystalliniformis Lee & Hur are described as new lichen species to science from the forested wetlands in southern South Korea. Molecular analyses employing internal transcribed spacer (ITS) and mitochondrial small subunit (mtSSU) sequences strongly support the two lecanoroid species to be distinct in their genera. Lecanora parasymmicta is included in the Lecanora symmicta group. It is morphologically distinguished from Lecanora symmicta (Ach.) Ach., its most similar species, by areolate-rimose thallus, blackish hypothallus, larger apothecia, absence of thalline excipulum from the beginning, narrower paraphyses, larger ascospores, smaller pycnoconidia, and the presence of placodiolic acid. The second new species Protoparmeliopsis crystalliniformis is included in a clade with Protoparmeliopsis bipruinosa (Fink) S.Y. Kondr. and P. nashii (B.D. Ryan) S.Y. Kondr., differs from Protoparmeliopsis ertzii Bungartz & Elix, its most morphologically similar species, by whitish thallus, flat to concave and paler disc, longer ascospores, thallus K+ yellow reaction, presence of atranorin and rhizocarpic acid, and the substrate preference to sandstone or basalt. A key is provided to assist in the identification of Protoparmeliopsis species in Korea.

The Status

Neorhagio Lindner was known to date exclusively from its type species, from Chile. The status of the genus among the Rhagionidae is controversial, sometimes confounded with Atherimorpha White or Rhagio Fabricius. Two new species of Neorhagio, N. caligatus sp. n. and N. nagatomii sp. n., are described and illustrated based on material collected in the Reserva ‘Biosfera’ El Triunfo, Northern Mexico. The differences between Neorhagio, Atherimorpha and Rhagio are considered, and comments are made on the presence of posteroventral cercal lobes in Rhagionidae.
