Specimens of monstrilloid copepods collected and described in the early 20 th century by G.O. Sars from the coasts of Norway and deposited in the Sars Collection (University of Oslo) were re-examined. Monstrilla leucopis Sars, 1921 was described based on female and male specimens, but the species was later synonymized with M. conjunctiva Giesbrecht, 1902 by several authors. Females of this species were analyzed and compared with closely related congeners, particularly with M. conjunctiva. This analysis includes the description of previously unknown morphological details following upgraded descriptive standards in this group. Evidence was found to support the notion that the female type specimens from Kvalø, Norway represent a distinct species; thus, M. leucopis is redescribed and reinstated as a valid taxon. Previous tropical records of female M. conjunctiva are questionable, but differences with M. leucopis can be found in body and antennule proportions, the structure of the genital spines and fifth legs, and most probably, their geographical ranges. Furthermore, M. leucopis has a modified thick-walled seta on the endopods of legs 2–4, so far a unique character among monstrilloids. The single male specimen labeled as M. leucopis in the Sars Collection was also examined and it is not the male of this species as depicted by G.O. Sars (1921). It is in fact a male of M. longiremis Giesbrecht, 1893, a species for which a short supplementary description and taxonomic comments are also provided herein. The male of M. leucopis also shares some important characters with that of M. conjunctiva, but also with another male specimen that was questionably assigned to the latter species; this male probably represents an undescribed species.

A Re-Examination of the type-specimens of “Sclerostoma” clathratum Baird from the African elephant, which are in the British Museum, has led to a rather interesting discovery. The material was contained in two bottles, labelled in Baird's own handwriting. One bore the name “Sclerostoma clathratum Baird,” and contained a single male specimen of the form now known as Grammocephalus clathratus. The other bottle was labelled “Sclerostoma clathratum Baird, ♀,” and proved to contain worms of both sexes and of quite a different type from Grammocephalus.

The Neotropical water scavenger beetle genus Globulosis García, 2001 is revised. Originally described from a single male specimen from southeastern Venezuela, the genus has since been found in localities across the Guiana Shield region and beyond, including Colombia, Suriname, Guyana, and Brazil. The genus is redescribed. Morphological characters and genetic data from the mitochondrial gene COI from ten populations across its range provide support for two distinct species, corresponding loosely to geography. The type species, G. hemisphericus García, is redescribed and newly recorded from Guyana, Suriname, and Brazil (Amazonas, Para). One new species is described, Globulosis flavus sp. n. from southwestern Venezuela (Amazonas, Bolivar). The genus is associated with lotic habitats, and typically found along the margins of small to medium sized streams. High-resolution habitus and aedeagal images and distribution maps for all species are provided.

The endemic Catantopinae genus Mopla was described by Henry in 1940 from the Malabar region of South India. Henry described two species under this genus, M. guttata and M. rubra. The female type specimens of Mopla are deposited in the Natural History Museum, London, UK. There have been no further records of these two species since their description. Seventy-six years later, the first male specimen of the genus Mopla was discovered in the Western Ghats, Kerala, India, in 2016. This paper describes the specimen, thought to be of Mopla guttata, and reconsiders its systematic placement.

Diagnostic Characters

The subgenus Bodilus Mulsant & Rey, 1870 of the genus Aphodius Helwig, 1798 sensu lato comprises 30 species in the Palearctic fauna (Frolov 2001, 2002, Dellacasa et al. 2016 [treated as genus Bodilus]). Frolov (2001) reviewed the species of this subgenus from Russia and adjacent countries and suggested that the monotypic subgenus Paramelinopterus Rakovič, 1984 shares the main diagnostic characters of Bodilus. Frolov (2001) was unable, however, to examine the type species of Paramelinopterus, A. longipennis Rakovič, 1984, at that time. Král (2016) suggested that A. (Bodilus) inylchekensis Frolov, 2001 is a junior synonym of A. longipennis. Recently we have re-examined all the types as well as the additional material accumulated in the museums and can confirm that A. inylchekensis is a distinct species, but A. insperatus Petrovitz, 1967 and A. longipennis cannot be reliably separated by the morphological characters. In the present contribution we illustrate the major diagnostic characters of the species based on the type specimens and also provide a distribution map of the known localities of the species.

Recent taxonomic studies on the genus Wahydra Steinhauser, 1991, have described five new species in the past two years, from high elevations in the Andes Mountains. A markedly distinct species of Wahydra is herein described and illustrated based on a single male specimen from Ecuadorian Andes, Wahydra graslieae A. Warren, Carneiro & Dolibaina, sp. nov. The new species is compared with other species of Wahydra, as well as with the somewhat similar species Lerema viridis (Bell, 1942) and Tigasis viridenex (Weeks, 1901).

First Time

The Egyptian fauna of the genus Ruppellia Wiedemann, 1830 is revised based on new material from Egypt, Israel, Oman, Tunisia, United Arab Emirates (UAE) and Yemen and on reexamination of the types in Egyptian collections. We recognize two distinct species: Ruppellia semiflava Wiedemann, 1830 and Ruppellia thoracica (Macquart, 1840). Ruppellia pallida Kröber, 1929 and Ruppellia apicalis Kröber, 1929 (new name = subapicalis Lyneborg, 1983) are synonymized with R. semiflava based on examination of the female type specimen of the former and the male type specimen of the latter species. Also, Thereva nuda Loew, 1856 is removed from synonymy with R. semiflava and placed as a new synonym to R. thoracica. Cataclinoneurum alexandrinum (Becker, 1912) is confirmed as a synonym to R. thoracica after we obtained pictures of the types. Ruppellia semiflava is recorded in Oman, UAE and Yemen for the first time. Ruppellia is redefined based on the number of dorsocentral setae. Illustrations, key, specimens examined and distributions are given for each species, along with color images of type specimens.

A New Species

A new species of the upogebiid shrimp genus Gebiacantha Ngoc-Ho, 1989, G. sagamiensis, is described and illustrated on the basis of a single male specimen collected from Sagami Bay, central Japan, at depths of 101–106 m. It appears closest to G. reunionensis Ngoc-Ho, 1989, known only from La Réunion, western Indian Ocean, but the different shape of the pleomere 6 and the better developed armature of the pereopod 1 carpus distinguish the new species from G. reunionensis. Comments on the taxonomic status of Gebiacantha and Paragebicula Sakai, 2006, and on the generic assignment of the new species, are given.

Two Populations

A number of populations of Leptolalax from Borneo and Peninsular Malaysia have been assigned to Leptolalax gracilis in thepast, rendering it a supposedly morphologically variable and widespread species. Whereas some of the Bornean populationshave since been described as distinct species, many lowland populations from Borneo and montane populations from Peninsu-lar Malaysia remain assigned to L. gracilis. Several distinct species appear to be hidden under this nominal taxon. In order toresolve the identity of L. gracilis and clarify the character states and their variation within the topotypic population, the speciesis redescribed based on examination of the holotype and recently collected topotypic material. Furthermore, the taxonomic sta-tus of two populations from Peninsular Malaysia (Gunung Benom, Gunung Tahan) that have been assigned to L. gracilis isreassessed. Reexamination of the corresponding vouchers revealed strong morphological differences between the two popula-tions and between each population and L. gracilis from Borneo. The population from Gunung Benom differs from all species ofthe genus and is apparently undescribed. The population from Gunung Tahan is represented only by two not fully metamor-phosed juveniles and cannot be assigned unambiguously to any of the described species of the genus. It is possibly another undescribed species but more specimens, especially adults, need to be collected.

The type specimens designated by Wilson (1911, Proc. U.S. Natl. Museum 39: 263–400) for Ergasilus versicolor do not agree with the description of that species but are conspecific with Ergasilus elegans Wilson, 1916; therefore, E. elegans is reduced to synonymy with E. versicolor, and a new description of E. versicolor is given, based on the type specimens. Wilson's (1911) description of E. versicolor appears to have been based on the type specimens as well as another, previously undescribed, species, Ergasilus arthrosis n.sp. Ergasilus celestis Mueller, 1936, was synonymized by Mueller (1936, Am. Midland Naturalist 17: 807–815) with E. versicolor, but it is here considered distinct and is redescribed.

The 19Th Century

Nereis falsa de Quatrefages, 1866 has been regarded as a cosmopolitan species, and several species described from different localities have been regarded as junior synonyms of N. falsa. The present study is an attempt to resolve the taxonomic confusion in N. falsa, which seems to contain several distinct species due to previous inappropriate synonymy, widely distributed in the Atlantic and eastern Pacific Oceans. For this purpose, the authors first propose the resurrection of the synonymy of N. falsa with Hediste diversicolor that was concluded during the 19th century but disregarded later. After the fixation of the identity of N. falsa sensu stricto, the authors re-evaluate the proper taxonomic status of species which have previously been confused with N. falsa. Type, topotype and non-type specimens were examined; most species are redescribed, and others are reinstated. Nereis splendida Grube, 1840 is a valid Mediterranean species, and a neotype is proposed; it includes the Mediterranean populations of what is currently regarded as N. falsa. Consequently, N. falsa is transferred to Hediste Malmgren, 1867, and some taxonomic comments are added for the latter genus and a key to species is also included. Nereis callaona Grube & Kröyer in Grube, 1857, N. marginata Grube & Örsted in Grube, 1857 and N. riisei Grube & Örsted in Grube, 1857 are restricted to tropical American shores and are all redescribed. Nereis pelagica lunulata Ehlers, 1901, formerly regarded as a junior synonym of N. falsa by Fauvel (1941), is redescribed and elevated in rank to species level. Nereis lucipeta Ehlers, 1908, formerly regarded as a junior synonym of N. splendida by Ehlers (1913) and of N. falsa by Fauvel (1919), is reinstated. Nereis occidentalis Hartman, 1945 is also redescribed. Furthermore, N. ambigua Treadwell, 1937, formerly regarded as a junior synonym of N. riisei by Monro (1933), deserves to be reinstated. Western Africa specimens recorded as N. falsa are newly described as N. mezianei sp. nov.
