Three species of Lophogastrida and eight Mysida are documented for samples from 5161–5497 m bottom depth in the Angola Basin. Previously known latitudinal ranges are extended southward for five species, and bathymetric ranges extended beyond 5000 m for six species. Upon revision of the subfamily Petalophthalminae (Mysidae), four species previously attributed to the genus Petalophthalmus are integrated into Ipirophthalmus gen. nov. as I. liui gen. et comb. nov., I. caribbeanus gen. et comb. nov., I. oculatus gen. et comb. nov., and I. macrops gen. et comb. nov., mainly based on the structure of eyes and presence of setae on the telson. Petalophthalmus cristatus sp. nov. is described based on its reduced cornea and the structure of eyestalks, rostrum, mandibles, and telson. The structure of mouthparts, foregut and maxillipeds suggests an omnivorous mode of life. The diagnosis of the tribe Calyptommini (Mysidae: Erythropinae) is widened to cover the 3-segmented, uniramous fourth male pleopod and the non-incised eyeplate with horn-like rudiments of eyestalks in Abyssomysis cornuta gen. et sp. nov. The structure of mandibles, foregut, and second maxilliped suggest detritus feeding in this species. Keys to the Calyptommini and Petalophthalminae are given.

The New Caledonian Archipelago is a hot spot for biodiversity and endemism. Whereas popular groups such as birds and plants are well-studied, invertebrate groups such as ostracods remain ill-known. Here, we re-describe Strandesia sanoamuangae Savatenalinton & Martens, 2010, originally described from Thailand (8000 km away from New Caledonia), and describe Strandesia mehesi sp. nov. Both species are known only from females. Material for the present study was collected from diverse aquatic non-marine habitats from Grande Terre, the main island of New Caledonia. Whereas S. sanoamuangae is seemingly easily identifiable, S. mehesi sp. nov. is part of the Strandesia vinceguerrae/vavrai species cluster in the genus, of which the 'older' species (described long ago) often have incomplete and superficial descriptions. Differentiation between the new species and the other members of this species cluster are based on small anatomical details of the valves. The current paper updates the known number of recent freshwater Ostracoda of New Caledonia from 14 to 16 species, although at least five of these species have an uncertain status.

A large, newly collected material of the genus Aquattuor from the Udzungwa Mts, Tanzania, has been studied. Two new species are described, viz., A. mollilobus sp. nov. from the Udzungwa Mts and A. nguruensis sp. nov. from the Nguru Mts, Tanzania. Aquattuor claudiahempae Enghoff & Frederiksen, 2015, is recorded as new for the Udzungwa fauna. Characters from the first pair of male legs are illustrated for all Aquattuor species and are shown to be useful for species discrimination. A new gonopodal difference between A. submajor Enghoff, 2015 and A. udzungwensis Enghoff, 2015 is described and illustrated. Intrageneric relationships and distribution patterns are discussed. A distribution map and a key to all Aquattuor species are presented.

Handbook of best practice and standards for 2D+ and 3D
imaging of natural history collections
(2020)
Digitising a collection is key to make it last even after the physical objects are no longer available. Almost all of the techniques currently available to digitise a natural history collection in 2D+ and 3D are listed herein. The techniques are explained in a way that even one without any knowledge on the subject may understand their principle. The strong and weak points of the techniques are discussed, and an overview of suitable collections and specimens are given for each one of them. Also, plenty of examples already digitised with each technique are provided together with the links to visualise them in 3D. After explaining all the different digitisation options, the subsequent chapters provide information on how to improve the 2D+ and 3D digital twins of the specimens and techniques are compared to each other by means of test specimens. These give a fast overview of the capabilities of the digitisation techniques. Possible solutions to avoid digitisation errors are equally provided. Lastly, the dissemination of the results and the data management of the 3D models are briefly discussed in the final chapters. Also, a large chapter is provided with several workflows that can be followed to get the best possible results.

In a recent project, extensive fieldwork was carried out in several parts of Sri Lanka to investigate scarab biodiversity. Here we present the first results of this survey and describe four new Sericini species: Selaserica athukoralai sp. nov., Neoserica dharmapriyai sp. nov., Maladera cervicornis sp. nov., M. galdaththana sp. nov. Further, new locality records for 20 already known species are given. The genitalia and the habitus of all new species are illustrated and photos of the habitats of the new species are given.

A new microscopic cnidarian is described, infecting five of thirty (16.6%) specimens of Corydoras schwartzi caught in the Purus River, State of Amazonas, Brazil. Histological analysis showed that cyst development occurred in the serosa layer of the intestine. Mature myxospores are ovoid in body shape in frontal view, 22.4 ± 0.3 μm in total length and 16.3 ± 0.1 μm in width. Internally, two aubergine-shaped, elongate symmetrical polar capsules occupy more than half the length of the spore, 14.3 ± 0.2 μm in length and 6.5 ± 0.1 μm in width. Ultrastructural analysis provided evidence of five polar filament coils inside the polar capsule and binucleated sporoplasm containing a moderate number of sporoplasmosomes. The valvogenic cells abutting each other form a sutural ridge and frequently a thin layer of homogeneous material separates the cells. The outer surface of the myxospore valves is smooth, with no evidence of formation of ridges in the valves. Immature myxospores in various stages of development were observed. This study is the first report of a myxosporean parasitizing C. schwartzi and the first report of a myxosporean infection in the intestine of an ornamental fish from South America.

This paper describes rare Cardiomya species from Brazil which have been hitherto misidentified as Cardiomya cleryana (d’Orbigny, 1842) in literature or museum collections. Cardiomya minerva sp. nov. is proposed as new species and is characterized by its quadrangular shell, short and truncated rostrum, and external ornamentation composed of six radial ribs on the posterior half of the shell flank. Cardiomya striolata (Locard, 1897) described from the Mediterranean Sea and northwestern Atlantic Ocean, is reported from Brazil for the first time; although previously regarded as a junior synonym of Cardiomya costellata (Deshayes, 1835), it is herein considered as a full species and redescribed. This species is characterized by its trapezoidal shell flank, elongated rostrum, tapering towards the tip, and external ornamentation composed of 18–53 radial ribs, the 3–4 posterior ones being the strongest and more widely spaced. Other three previously unknown species are illustrated but not formally named due to the lack of well-preserved articulated shells.

In this paper the primary types of Centris bees described by the British entomologist Theodore Dru Alison Cockerell deposited in the Natural History Museum (London) and the Oxford University Museum of Natural History (Oxford) in the United Kingdom, as well as in the United States National Museum (Washington), American Museum of Natural History (New York), the Academy of Natural Sciences of Drexel University (Philadelphia), and in the California Academy of Sciences (San Francisco) in the United States were studied. To stabilize the application of the name C. lepeletieri (= C. haemorrhoidalis (Fabricius)), a lectotype is designated. The study of the primary types allow proposing the revalidation of C. cisnerosi nom. rev. from the synonymy of C. agilis Smith, C. nitida geminata nom. rev. from C. facialis Mocsáry, C. rufulina nom. rev. from C. varia (Erichson), C. semilabrosa nom. rev. from C. terminata Smith and C. triangulifera nom. rev. from C. labrosa Friese. Centris bakeri syn. nov., C. bimaculata carrikeri syn. nov., C. fusciventris matoensis syn. nov., C. heterodonta syn. nov. and C. elegans grenadensis syn. nov. are proposed as a new junior synonyms of C. varia, C. claripennis Friese nom. rev., C. caurensis, C. dentata Smith and C. elegans Smith, respectively. Centris ruae is withdrawn from the synonymy of C. transversa Pérez and proposed as a new junior synonym of C. nitida Smith. In addition, a lectotype for C. buchholzi Herbst (= C. wilmattae) is designated. Information on the repository of the lectotype of C. lepeletieri and images of most primary types studied here are also provided.

Cloeon perkinsi was described from South Africa in 1932 by Barnard. Despite being relatively common in Africa, it was mentioned in the literature quite rarely, and its known distribution to date includes most of sub-Saharan Africa. Material collected recently in Ethiopia, Israel, Saudi Arabia, and Yemen extends its distribution in East Africa, Arabian Peninsula and the Levant. We examined this material, and provide a re-description of adults (females and males) and nymphs of the species. It represents a much-needed urge mainly due to inconsistencies in literature reports regarding colouration, and sometimes incomplete morphological description of all stages. We demonstrate the intraspecific morphological variability that we have witnessed, and provide information regarding the range of habitats colonised by C. perkinsi. Based on geological and climatic history of the studied region, taken together with among countries genetic distances of the mitochondrial barcoding gene COI, we propose colonisation mechanisms for the north-easternmost limit of distribution. The fragmented distribution pattern of the species highlights the conservation importance of isolated aquatic habitats in the region, as well as current knowledge gaps.

We studied the cestode fauna (Platyhelminthes) of forest birds in Malaysia (Selangor) collected during a field trip in 2010. Ninety birds of 37 species were examined and global prevalence of cestodes was 15.3%. Five new taxa are described: Emberizotaenia aeschlii sp. nov. (Dilepididae) from Tricholestes criniger (Blyth, 1845) (Pycnonotidae); Anonchotaenia kornyushini sp. nov. (Paruterinidae) from Trichastoma malaccense (Hartlaub, 1844) (Pellorneidae); Biuterina jensenae sp. nov. (Paruterinidae) from Chloropsis cochinchinensis (Gmelin, 1789) (Irenidae); Raillietina hymenolepidoides sp. nov. (Davaineidae) and R. mahnerti sp. nov. (Davaineidae) from Chalcophaps indica (Linnaeus, 1758) (Columbidae). Ophryocotyloides dasi Tandan & Singh, 1964 is reported from Psilopogon henricii (Temminck, 1831) (Ramphastidae). Several other taxa in Dilepididae, Davaineidae, Paruterinidae, Hymenolepididae and Mesocestoididae, either potentially new or poorly known, are also reported. The richness described from this small collection hints at the potentially huge unknown parasite diversity from wild hosts in this part of the world.

Sixteen aglaopheniid hydroids occurring in two recent, deep water collections from off New Caledonia are reported upon, of which 8 species are new, namely Cladocarpus asymmetricus sp. nov., C. partitus sp. nov., C. pennatus sp. nov., Lytocarpia fragilis sp. nov., L. pilosa sp. nov., L. pseudoctenata sp. nov., L. subtilis sp. nov. and Macrorhynchia spiralis sp. nov., the latter producing medusoid gonophores. Although not occurring in the present collections, brief notes on M. disjuncta (Pictet, 1893), including the first description of its gonosome, are provided to support its specific separation from M. phoenicea (Busk, 1852).

In this paper we describe Macrobiotus engbergi sp. nov. and Tenuibiotus zandrae sp. nov. from Greenland. Our study has involved both classical taxonomic methods, which include morphological and morphometric analyses conducted with the use of light and scanning electron microscopy, and genetic analysis based on four molecular markers (three nuclear: 18S rRNA, 28S rRNA, ITS-2, and one mitochondrial: COI). Moreover, we re-examined the type series of Tenuibiotus voronkovi (Tumanov, 2007) as well as the original sample where the species was found and we provide new morphological data from light and scanning electron microscopy which enabled us to amend its description. Finally, we also analysed slides with animals and egg of two populations from Nordaustlandet and Edgeøya (archipelago of Svalbard, Norway) designated as T. voronkovi within its recent redescription. The results and comparisons presented in our study question the validity of this designation.

A new symbiotic species of liljeborgiid amphipods, Liljeborgia associata sp. nov., is described from the burrows of the spoon worm Urechis unicinctus (Drasche, 1880) (Annelida: Polychaeta: Echiura: Urechidae) in the southern part of Peter the Great Bay and Posjeta Bay in the Sea of Japan. The new species is mostly similar and probably related to Liljeborgia geminata Barnard, 1969, known from the Californian coasts of the USA, and Liljeborgia serratoides Tzvetkova, 1967, described from Posjeta Bay in the Sea of Japan, but can be clearly distinguished from all congeners by morphological features of mouthparts, appendages and telson. The new species is only the fourth in the family Liljeborgiidae to be described from the Russian coast of the northwestern Pacific and the first in association with spoon worms (Echiura).
612
A new genus of Baetidae is described from Southeast Asia, Procerobaetis gen. nov. It has a wide distribution reaching from Indonesia (Sumatra) to the Philippines. Two new species are described from Indonesia, P. leptobranchius gen. et sp. nov. and P. petersorum gen. et sp. nov., and one new species from the Philippines, P. freitagi gen. et sp. nov. Procerobaetis gen. nov. is characterized by having seven pairs of elongate, apically pointed gills. At least gills I and II are very slender with strongly extended points, which is unique in Baetidae. Similar gills were described from Leptophlebiidae. Procerobaetis gen. nov. is further characterized by having long, slender legs with extended, slender and slightly bent claws. The antennae posess remarkable spines at the outer, lateral margin, which are maximally developed on segments IX–XI of the flagellum. No spines are present on the posterior margins of abdominal tergites I–VI. COI sequences were obtained from all three of the new species. The genetic distances (Kimura 2-parameter) between these species are between 13% and 20%. Very limited genetic distances of 0% to 1% were found between specimens of the same species. The occurrence of two different species in the same area of Sumatra is discussed.
611
A new jumping spider genus, Manzuma gen. nov. (Salticidae Blackwall, 1841), is described, type species is Manzuma nigritibia (Caporiacco, 1941). Aelurillus reconditus Wesołowska & van Harten, 1994 is synonymized with Rafalus nigritibiis (Caporiacco, 1941). Four new combinations are proposed: M. jocquei gen. et comb. nov. (ex Aelurillus), M. kenyaensis gen. et comb. nov. (ex Langelurillus), M. lympha gen. et comb. nov. (ex Rafalus) and M. nigritibia gen. et comb. nov. (ex Rafalus). Three species, M. botswana gen. et sp. nov. (♂♀, Botswana and Republic of South Africa), M. petroae gen. et sp. nov. (♂♀, Republic of South Africa) and M. tanzanica gen. et sp. nov. (♂, Tanzania), are described. The male of M. kenyaensis gen. et comb. nov. and female of M. lympha gen. et comb. nov. are described for the first time. A new aelurilline synapomorphy is proposed. Identification key for males is provided.

Micropterigidae is a family of Lepidoptera characterized by plesiomorphic morphological characters. Presently, this family consists of more than 22 genera and is distributed throughout all biogeographic realms. Vietomartyria Hashimoto & Mey, 2000 presently consists of six species mainly from South China. Two new species of the genus, V. wuyunjiena sp. nov. and V. maoershana sp. nov., are described herein from China; adult genitalia and wing venation are illustrated. Some biological accounts of the new species are also provided. A key to all described Vietomartyria species is given.

Recent studies have shown that the speciose Holarctic genera of Leiobunum C.L. Koch, 1839 and Nelima Roewer, 1910 are polyphyletic taxa, and therefore, the traditional diagnostic characters for these European genera of Leiobuninae Banks, 1893 (respectively, the presence or absence of tubercle rows on leg coxae) are unsuitable. We present the description of Leiolima iberica gen. et sp. nov., a new endemic harvestman from the north-western part of the Iberian Peninsula. The newly established genus shows intermediate characters between Leiobunum and Nelima. In addition, the new genus is characterized by shorter legs compared to Leiobunum and the presence of trichomes on all leg femora and pedipalpal patellae, a structure that is absent in all other western Palearctic genera of the subfamily Leiobuninae.
