Partial redescriptions of three holothurians with “hook papillae” (Apodida: Chiridotidae): Taeniogyrus japonicus (Marenzeller, 1882), T. dendyi (Mortensen, 1925), Scoliorhapis theelii (Heding, 1928)

2022-05-19T12:19:24+12:00

New specimens of Taeniogyrus japonicus (Marenzeller) were collected from Iwami coast and Sado island of the Sea of Japan. According to detailed observations of external and internal organs, we transferred T. japonicus, T. dendyi (Mortensen), and Scoliorhapis theelii (Heding) to the newly revived genus Scoliodota, with a large retractor organ and hook papillae as major diagnostic characters. We also concluded that Scoliorhapis dianthus Solis-marin et al. is a synonym of T. japonicus. Our molecular phylogeny and genetic distance analysis showed that specimens from Iwami and specimens from Sado of T. japonicus form a monophyletic clade, indicating that they are most likely the same species despite their morphological variation. The phylogenetic analysis also indicated that T. japonicus forms a sister group relationship with Taeniogyrus verruculosus Yamana & Tanaka and Scoliorhapis sesokoensis Yamana & Tanaka, suggesting that Taeniogyrus is not monophyletic. Taken together, these results brought new insights to sea cucumber diversity in Japanese waters.

A new species and new records of Gnorimoschemini (Lepidoptera, Gelechiidae) from Ecuador

2022-05-19T12:19:15+12:00

Scrobipalpula onorei sp. nov. is described from Las Pampas, Ecuador. The species is tentatively placed near Scrobipalpula densata (Meyrick, 1917) and S. caustonae Landry, 2010 based on both having a slender, elongate phallus and a bipartite corpus bursae without a signum. Eurysacca media Povolný, 1986 is recorded for the first time from Ecuador. Sexual dimorphism in structures of abdominal segments VII–VIII are described for the first time for E. media. The female of this species has patches of melanized scales on abdominal segment VII. The diagnosis of the species is updated with descriptions and illustration of additional details of external morphology and characters of male and female genitalia. We also provide an annotated list of Gnorimoschemini from Ecuador.

**Korean species of the Atheta Thomson subgenus Dimetrota Mulsant & Rey (Coleoptera: Staphylinidae: Aleocharinae) with a description of new species**

2022-05-19T12:19:01+12:00

A taxonomic review of the Atheta Thomson subgenus Dimetrota Mulsant & Rey in the Korean Peninsula is presented. The subgenus is represented in Korea by 11 species including a new species, A. (D.) ovata Lee & Ahn, sp. nov. and a new synonym [A. (Badura) tokiokai Sawada = A. (D.) chagangensis Paśnik syn. nov.]. Atheta (D.) yamamotoi Sawada is reported for the first time in the Korean Peninsula and A. (D.) machonryongica in South Korea. A key to Korean species and descriptions with illustrations of habitus photographs and diagnostic characters of three species new to Korea are provided.

**Rediscovery and systematics of the rarely encountered Blue-bellied kukri snake (Oligodon melaneus Wall, 1909) from Assam, India**

2022-05-19T12:18:57+12:00

We report the rediscovery of Oligodon melaneus 112 years after its original description and document the third, and only non-type, specimen for the species. The new specimen was found 267 km east of the type locality (Tindharia, West Bengal state) from Assam state, India. We designate a lectotype for the species, and provide an extended description of a freshly collected male specimen. Phylogenetic analyses of 16s and cytb mitochondrial genes provide support for O. melaneus being closely related to the widespread South Asian endemic O. arnensis.

Two species of metallic Microlepidoptera, one new species of Adela Latreille, [1796] (Adeloidea, Adelidae) and one unrecorded species of Coleophora Hübner, 1822 (Gelechioidea, Coleophoridae), from Korea

2022-05-19T12:18:53+12:00

One new species of Adela Latreille, [1796], A. palella Koo & Cho, sp. nov., belonging to Adelidae is described from Korea, and one species of Coleophora Hübner, 1822, C. fuscocuprella Herrich-Schäffer, 1855, belonging to Coleophoridae is reported for the first time. Diagnostic characters and descriptions are provided along with close-up photographs of notable features of adults.

Updated taxonomy of Syntermitinae (Blattodea: Isoptera, Termitidae), with the description of three new genera

2022-05-19T12:18:49+12:00

Herein we describe three new genera based on a previous phylogenetic analysis of the termite subfamily Syntermitinae (Termitidae), which indicated that the genera Embiratermes Fontes and Ibitermes Fontes were paraphyletic. In order to resolve this paraphyly, the genus is more narrowly circumscribed, resulting in the following taxonomic changes: Biratermes gen. n., is established to accommodate Embiratermes robustus Constantino, 1992; Vaninitermes gen. n. is described for Armitermes brevinasisus Emerson & Banks, 1957 and E. ignotus Constantino, 1991; and Bandeiratermes gen. n., is proposed to accommodate Armitermes silvestrii Emerson in Snyder, 1949 and Ibitermes tellustris Constantino, 1990. In addition, E. parvirostris Constantino, 1992 is considered a new junior subjective synonym of E. ignotus, and the imago of E. ignotus is described for the first time. Descriptions and illustrations of the workers’ digestive tube are included for all species, along with drawings of the coiling worker gut of E. festivellus (Silvestri, 1901). Photographs are provided for the soldiers of all of the aforementioned species. The new genera are compared with all other genera of Syntermitinae.

**Review of some mites of the genus Ololaelaps Berlese (Acari, Laelapidae) in Russia, with description of a new species**

2022-05-19T12:18:43+12:00

This study provides additional morphological information and new illustrations for three species of Ololaelaps Berlese described by Bregetova & Koroleva (1964) from Russia—O. caucasicus, O. sellnicki and O. ussuriensis—to supplement the original descriptions. Since holotypes for these three species were not designated, a lectotype is chosen from among the syntypes of each examined species. We describe the adult male and female of Ololaelaps altaiensis Joharchi sp. nov., from specimens collected from moss on the shore of the Teletskoye Lake, in Altai Mountains, Russia. The new species is distinguished from other Ololaelaps species by its short peritremes, ending near the middle of coxae II. The new species also has elongate paradactyli, extending well beyond the pretarsal claws; this feature appears to be correlated with the species’ semiaquatic habitat, and such correlation between tarsal morphology and ecology occurs in other species of Ololaelaps and of Gaeolaelaps with similar habitats.

**Review of the genus Stictane Hampson (Lepidoptera, Erebidae, Arctiinae) in Thailand with description of a new species**

2022-05-19T12:18:39+12:00

The genus Stictane Hampson is reviewed in Thailand, which is represented with 11 species including seven newly recorded and one newly described species, S. bokorensis, S. cambodiensis, S. fuscus, S. gemina, S. kualabohi, S. mlcochi, S. transversana and S. trigonica sp. n. Females of S. kualabohi and S. cambodensis are studied for the first time. Illustrations showing the general view of the body of adults and genitalia of all examined species from Thailand are provided.

2022-05-19T12:18:36+12:00

Three suctorian ciliate species, Paracineta livadiana (Mereschkowsky, 1881), Loricophrya bosporica Sergeeva & Dovgal, 2014 and Acinetopsis lynni Baldrighi et al., 2020 are found as epibionts on meiobenthic nematodes in an oxygen minimum zone of the Arabian Sea. All three species are recorded here for the first time from the Indian Ocean.
