Sea lice (Copepoda: Caligidae) from South Africa, with descriptions of two new species of Caligus

Thirteen species of sea lice (family Caligidae) are reported from a range of elasmobranch and actinopterygian fishes caught off South Africa or obtained from public aquaria in South Africa. Two new species of Caligus Müller, 1785 are described: C. linearisn. sp. from Pomatomus saltatrix (Linnaeus) and C. tumulusn. sp. from Chrysoblephus cristiceps (Valenciennes). A supplementary description is provided for both sexes of Caligus tetrodontis Barnard, 1948 taken from Amblyrhynchotes honckenii (Bloch) and previous records of this parasite from South African fishes are critically reviewed. It is concluded that Caligus material from Arothron hispidus Linnaeus was previously misidentified as C. tetrodontis and is in urgent need of re-examination. Morphological and molecular observations on Caligus furcisetifer Redkar, Rangnekar & Murti, 1949 indicate that this copepod is phenotypically and genetically identical to Lepeophtheirus natalensis Kensley & Grindley, 1973, and the latter becomes a junior subjective synonym of C. furcisetifer. We include new geographical distribution records for Caligus longipedis Bassett-Smith, 1898, C. rufimaculatus Wilson, 1905 and Lepeophtheirus spinifer Kirtisinghe, 1937, extending into South African waters, as well as both new distribution and host records for Alebion gracilis Wilson, 1905, Caligus dakari van Beneden, 1892 and Lepeophtheirus acutus Heegaard, 1943. The molecular analysis confirmed the monophyly of the genus Caligus. The South African species of Caligus did not cluster together, but the two included South African species of Lepeophtheirus were recovered as sister taxa.

Notes on Indian wolf spiders: I. Genus Evippa Simon, 1882 (Araneae: Lycosidae, Evippinae).

Indian wolf spider species of the genus Evippa Simon, 1882 based on the type material available in the National Zoological Collection, Zoological Survey of India, Kolkata are revised. One new synonymy is recognised: Evippa mandlaensis Gajbe, 2004 syn. nov. is synonymised with Wadicosa fidelis (O. Pickard-Cambridge, 1872). All the type material examined are imaged and supplementary descriptions for Evippa shivajii Tikader Malhotra, 1980, Evippa sohani Tikader Malhotra, 1980, and Evippa solanensis Tikader Malhotra, 1980 are provided.

A new species of Nemoura (Plecoptera, Nemouridae) and supplementary description of Amphinemura cordiformis from the Nanling Mountains of southern China.

Two species of Nemouridae are described and illustrated from the Nanling Mountains of southern China, including a new species, Nemoura biplattasp. nov. from Guangxi Zhuang Autonomous Region, and a new regional record species, Amphinemura cordiformis Li & Yang, 2006 from Hunan Province.

First record of adult Dorytocidae — Dorytocus jiaxiaoae Song, Szwedo & Bourgoin sp. nov. (Hemiptera: Fulgoromorpha: Fulgoroidea) from mid-Cretaceous Kachin amber

A new species, Dorytocus jiaxiaoae Song, Szwedo & Bourgoin sp. nov., from the mid-Cretaceous Burmese amber is described and illustrated. This species represents the first record of the adult of the extinct family Dorytocidae. The supplementary description for the fourth-instar nymph of Dorytocus ornithorhynchus Emeljanov & Shcherbakov is provided. The morphological peculiarities of the new fossil species are briefly discussed, and family diagnosis is now based on the combination of both adult and nymph characters.

A new species of Cybaeus L. Koch, 1868 (Araneae, Cybaeidae) with simple genitalia from central Japan is the sister species of C. melanoparvus Kobayashi, 2006 with elongated genitalia

Spiders of the genus Cybaeus L. Koch, 1868 exhibit two major centers of diversity: Western North America and Japan. Several Japanese Cybaeus possess an elongated embolus in the male palp and elongated tubular spermathecae in the female genitalia. Here we describe Cybaeus koikeisp. nov. from central Honshu, Japan, which has an unelongated embolus and bulbous spermathecae. Phylogenetic analyses using nuclear and mitochondrial gene markers clearly support the monophyly of C. koikeisp. nov. and Cybaeus melanoparvus Kobayashi, 2006, a species with elongated genitalia. Both species share a similar habitus and a cluster of robust setae on the lateral surface of the male palpal patella. The latter is considered a synapomorphy for C. koikeisp. nov. and C. melanoparvus. A supplementary description of the spermathecae of C. melanoparvus is also provided.

A new species and new synonym of Amphinemura (Plecoptera: Nemouridae) from Zhejiang province of China

ABSTRACT We examined specimens of Amphinemura from Zhejiang Province housed at the Insect Collection of Yangzhou University. Among these specimens, we describe and illustrate Amphinemura oxyacantha sp. nov. Also found were relatively fresh specimens of Amphinemura chui Wu, 1935. Comparison of these with recent descriptions and illustrations of A. guangdongensis Yang, Li & Zhu, 2004 leads us to conclude that the latter is a synonym of A. chui. Supplementary description and illustration of A. chui facilitate comparison and identification of this species.

Taxonomic notes on the genus Makdiops Crews amp; Harvey, 2011 in India (Araneae: Selenopidae).

The selenopid genus Makdiops Crews Harvey, 2011 was recently erected by Crews and Harvey (2011) with Selenops montigena Simon, 1889 as the type species. The genus represents medium-sized, usually high-altitude-dwelling spiders that can be diagnosed by the pattern of ventral spination of the anterior tibiae and metatarsi (4-3, 3-3 or 3-2) and by the absence of tarsal scopulae (Crews Harvey 2011). The genus is restricted to India (five species) and Nepal (one species) (Crews Harvey 2011; Caleb Sankaran 2020; World Spider Catalog 2020). While erecting the new genus, Crews and Harvey (2011) transferred two species formerly placed in Selenops Latreille, 1819: Selenops montigena Simon, 1889 and Selenops agumbensis Tikader, 1969. However, they did not examine the types of these two species due to their unavailability, and both these transfers were based either only on the original or subsequent descriptions/re-descriptions of these species. In this paper, we present images of the types of these two species and transfer Selenops shevaroyensis Gravely, 1931 to Makdiops. Additionally, we provide supplementary descriptions for the types of M. montigena, M. agumbensis and M. shevaroyensis comb. nov..

All the examined type specimens are imaged and supplementary descriptions are provided.

Tag-informed collaborative topic modeling for cross domain recommendations

Collaborative topic modeling is powerful to alleviate data sparsity in recommender systems owing to the incorporation of collaborative filtering and topic models. However sufficient textual data is not always available. On the other hand, tags serving as supplementary description of items can reflect users’ interests in item attributes. But previous works only mine the effect of tags on ratings in one domain and ignore that in related domains items can be related in attributes. Tags encode similar properties of items and can be transferred across domains to mutually benefit recommendations for both domains. In this study we propose a TagCDCTR (Tag-informed Cross Domain Collaborative Topic Regression) model, which exploits shared tags as bridges to link related domains through an extended collaborative topic modeling framework. The model exploits the inter-domain relations by encoding cross domain item–item similarity based on common tags and jointly learning a shared set of topics from all domains together. Collectively factorizing the rating matrices of multiple domains into common user latent factors and domain-specific item latent factors, so that the learned item latent factors are linked through the inter-domain relations, helping to capture the items more comprehensively. The rich information reused in multiple domains alleviates data sparsity and the semantic advantage of topics and tags provides a better interpretability of recommendations. The experiments conducted on three datasets demonstrate that TagCDCTR outperforms state-of-the-art collaborative-topic-based models and cross-domain-based models.
