Morphological ontogeny of Neoseiulus zwoelferi (Acari: Phytoseiidae)

The morphological ontogeny of Neoseiulus zwoelferi (Dosse, 1957) (Acari: Phytoseiidae) was studied based on specimens from a laboratory culture originally collected from the leaves of Xanthium sibiricum Patrin ex Widder (Asteraceae) in Taigu County, Shanxi province, China. All life stages including larva, protonymph, deutonymphal female and male, adult female and male were described and illustrated. The morphological characters of Neoseiulus species with both immature and adult stages are discussed. Neoseiulus subreticulatus (Wu, 1987) is considered a junior synonym of Neoseiulus zwoelferi (Dosse, 1957).

Revision of the Australian genus Alfredella Masner & Huggert (Hymenoptera, Platygastridae, Sceliotrachelinae)

The genus Alfredella Masner & Huggert is revised. Alfredella tasmanica Masner & Huggert is redescribed, Al. teres (Buhl), comb. nov. is transferred to Alfredella from Amitus Haldeman, and Al. auriel Lahey, sp. nov. (New South Wales, Tasmania) and Al. mephisto Lahey, sp. nov. (Western Australia) are described as new. The genus Masnerium Polaszek, syn. nov. is treated as a junior synonym of Amitus, and its type species, M. wellsae Polaszek, is transferred to Amitus as Am. wellsae (Polaszek), comb. nov. The relationship between Alfredella and morphologically similar genera is discussed, and a key is provided to distinguish between Aleyroctonus Masner & Huggert, Alfredella, and Amitus.

Checklist and keys to Deltocephalinae leafhoppers (Hemiptera, Cicadellidae) from Pakistan

Keys to all levels of the subfamily Deltocephalinae (Hemiptera: Cicadellidae) of Pakistan are provided based on published records and original data from recent research. Checklists to the genera and species of Deltocephalinae are also given. A total of 49 genera with more than 100 species are now known from Pakistan.

Illustrated key to the genera included in the tribe Acanthocephalini (Hemiptera: Heteroptera: Coreidae: Coreinae), with descriptions of three new genera, seven new species, new taxonomic rearrangements, and a key to genera of Placoscelini

Three new genera and seven new species of Acanthocephalini Stål (Hemiptera: Heteroptera: Coreidae) are described: Anomalopetalops with three new species, A. brulei (French Guiana), A. ariquemesus (Brazil), and A. diamantinus (Brazil); Antipetalops with two new species, A. colombianus (Colombia), and A. discretus (Bolivia); and Cryptopetalops with two new species, C. llorentei (Brazil and French Guiana), and C. pluteus (Peru). Dorsal habitus photographs, and keys to the new species of each genus are added. Dorsal habitus photographs and a key to the 18 known genera of Acanthocephalini are given. Placophyllopus Blöte, 1938 is synonymized under Meluchopetalops Breddin, 1903. Placophyllopus cothurnatus Blöte, 1938 is considered a junior synonym of Meluchopetalops banausus Breddin, 1903. Bermejanus Brailovsky, 2018 is transferred to the tribe Placoscelini, and a key to the known genera of that tribe is provided.

Clitobius grimmi sp. n. from Egypt with notes on C. oblongiusculus (Fairmaire, 1875) (Coleoptera: Tenebrionidae: Blaptinae)

Ten valid species of the genus Clitobius Mulsant & Rey, 1859 have been published so far from the Palaearctic, Afrotropical and Oriental Regions. With C. grimmi sp. n. from Egypt an eleventh species is here described and illustrated. Specimens representing the newly proposed species were identified as C. oblongiusculus (Fairmaire, 1875) in many of the surveyed entomological collections. This could potentially be explained by the superficial convergence of C. grimmi sp. n. with the description of Halomenus lineicollis Fairmaire, 1879, which is now considered a junior synonym of C. oblongiusculus. Morphological distinctiveness of all of the above mentioned taxa is hereby discussed. The lectotype for Halonomus lineicollis Fairmaire, 1879 is designated in order to fix the nomenclatural status of that taxon. The determination key of Purchart & Kamiński (2017) to the Clitobius species is updated with the following taxa: Clitobius subplumbeus (Fairmaire, 1892) and C. grimmi sp. n.

About the identity of Granulina pusaterii Smriglio & Mariottini, 2003 (Volutoidea: Granulinidae) from the Tunisian Plateau

On the ground of an extensive study of topotypes and of the shell morphology documented in comparable Mediterranean populations, Granulina pusaterii Smriglio & Mariottini, 2003 described from the Tunisian Plateau is proved to belong to the natural variability of G. melitensis Smriglio, Mariottini & Rufini, 1998 and it is proposed as junior synonym name of the latter.

New species and records of the Neotropical genus Cyrnellus (Trichoptera: Polycentropodidae) and the re-establishment of C. minimus and C. marginalis

Cyrnellus is a small genus of Polycentropodidae distributed in the Nearctic and Neotropical regions, absent from the Chilean subregion. Two new species are here described: C. boliviensis sp. nov. and C. guyanensis sp. nov. Cyrnellus minimus Banks 1913 considered as a junior synonym of Cyrnellus fraternus (Banks 1905) by Flint (1971) and C. marginalis (Banks 1930) considered as a junior synonym of Cyrnellus fraternus by Flint (1964) are revalidated at the specific level. We provide a key and illustrations for adult males and nine new country records for Bolivia.

Review of the hyperiidean amphipod family Lycaeidae Claus, 1879 (Crustacea: Amphipoda: Hyperiidea)

This is the first comprehensive taxonomic review of the family Lycaeidae. This study is based primarily on the extensive collections of the Natural History Museum, Denmark (NHMD, formerly ZMUC) and the US National Museum of Natural History, Smithsonian Institution, Washington DC, USA (USNM), and on additional material from the South African Museum (SAM) and in the South Australian Museum (SAMA). The two currently recognized genera in the family, Lycaea Dana, 1852 and Simorhynchotus Stebbing, 1888, are maintained with the latter still regarded monotypic with S. antennarius (Claus, 1871). Characters used to distinguish species in the past are re-evaluated in order to determine their validity. There are 15 nominal species of Lycaea in the literature, excluding Pseudolycaea pachypoda Claus, 1879 and Metalycaea globosa Stephensen, 1925. Pseudolycaea Claus, 1879 is regarded a synonym of Lycaea, as confirmed by this study, and M. globosa is a junior synonym of L. serrata Claus, 1879, as demonstrated by an examination of the type material. Of the remaining nominal species many have been synonymized with L. pulex Marion, 1874 in the past, often based on erroneous literature references. Thus, the taxonomic status of all nominal species was redetermined by the examination of type material or from the original literature reference if type material could not be found. In conclusion, ten species of Lycaea are recognized as valid, including three described as new. Lycaea bovallii Chevreux, 1900 is determined to be a valid species with the following as junior synonyms, L. gracilis Spandl, 1924, L. bajensis Shoemaker, 1925 and L. bovallioides Stephensen, 1925. It seems to be widely distributed and relatively common in the tropical regions of all the world’s oceans, including the Mediterranean Sea. The other species recognized as valid are L. lilia Volkov, 1982; L. nasuta Claus, 1879; L. pachypoda (Claus, 1879); L. pulex Marion, 1874 (L. robusta Claus, 1879, L. similis Claus, 1879 and L. pauli Stebbing, 1888 regarded junior synonyms); L. serrata Claus, 1879 and L. vincentii Stebbing, 1888 (Amphipronoe longicornuta Giles, 1888 a junior synonym). In addition, three species are described as new to science; L. intermedia sp. nov., L. proserrata sp. nov. and L. osbornae sp. nov. All were found in the tropical regions of the Atlantic, Pacific and Indian Oceans; the former two are relatively common and widespread. All species are described and illustrated and a key is provided to facilitate their identification.
