Two new genera and species of tiger beetles from Baltic amber (Coleoptera: Carabidae: Cicindelinae)
(2017)
Two fossil tiger beetle species (Coleoptera, Carabidae, Cicindelinae) are described from Eocene Baltic amber using light microscopic and X-ray microscopic techniques. Both species are considered representatives of the subtribe Iresina Rivalier, 1971 due to the shared combination of character states: glabrous head, six labral and four suborbital setae, and glabrous pronotum. Palaeopronyssiformia groehni Wiesner, Will, and Schmidt, new genus, new species, is characterized by a glabrous and furrowed head with six labral setae, large eyes, presence of two supraorbital setae on each side, mandibles with two teeth of the incisor region, and a glabrous and furrowed pronotum. Palaeoiresina cassolai Wiesner, Will, and Schmidt, new genus, new species, is characterized by a unicolored, undentated labrum, mandibles with two teeth of the incisor region, glabrous head with six labral setae, two clypeal setae, two supraorbital setae on each side, and a glabrous pronotum, mesepisternum, mesepimeron, and metepisternum. The species described here represent the only known tiger beetle fossils preserved in Baltic amber.
Examination of leucothoid amphipods of the Red Sea has revealed seven species not previously reported from this location. Leucothoe minoculis sp. nov., Leucothoe pansa sp. nov., Leucothoe reimeri sp. nov., and Paranamixis sommelieri sp. nov. are described and the range of Leucothoe predenticulata Ledoyer, 1978, L. acutilobata Ledoyer, 1978 and L. squalidens Ledoyer, 1978 is expanded to include the Red Sea. Clarification of reports of L. acanthopus Schellenberg, 1928 and L. bannwarthi (Schellenberg, 1928) is provided and Leucothoe alani sp. nov. is described from outside the Red Sea.
Two Mastogloia Thwaites ex W.Sm. taxa were found during a survey of the diatom flora of Lac de Guiers, Senegal. Based on all currently available literature, one taxon could be identified as M. belaensis M.Voigt, a species formerly described from Pakistan. The second species showed some resemblance to M. braunii Grunow. Analysis of the type of M. braunii revealed, however, important morphologic differences, leading to the description of a new species from the Senegal population: M. senegalensis Van de Vijver, Fofana, Sow & Ector sp. nov. The present paper describes this new species and discusses and illustrates the morphology of M. belaensis and the type of M. braunii. All taxa are discussed with morphologically similar taxa.
A new species of the genus Teinobasis Kirby is described from the Muller Range in Western Province, Papua New Guinea. Its male is distinguished from all other Teinobasis species by having a pale labrum, an extensively bright orange thorax, and ventrally bowed superior anal appendages that are markedly shorter than the plump, apically rounded inferiors. Characters of the male are illustrated, and the affinities of the new species are discussed.
The Afrotropical planthopper genus Centromeriana Melichar, 1912 (Hemiptera, Fulgoromorpha, Dictyopharidae, Dictyopharinae, Orthopagini) is revised. Four species are included: C. jocosa (Gerstaecker, 1895) (the type species, with confirmed records from Cameroon, Equatorial Guinea and Gabon), C. lindbergae sp. nov. (described from Sierra Leone), C. rhinoceros sp. nov. (described from Togo) and C. simplex Melichar, 1912 (so far only known from Equatorial Guinea, Bioko island). Lectotypes are designated for C. jocosa and C. simplex and both species are redescribed including habitus photographs and detailed illustrations of the male and female genitalia which are published for the first time. A key for identification of the species of Centromeriana is provided. As far as known, the genus is endemic to the (Guineo-)Congolian region of western Africa.
Haplosclerid sponges possessing a unique asymmetric flagelliform type of sigmoid microsclere have been reported from all global oceans. This peculiar spicule, characterized by a circular or elliptical shape, with a longer and sharper curved ending at one side and a shorter and more gradually curved ending at the opposing side, is proposed to be termed ‘flagellosigma’. These sponges invariably also possess smaller normal sigmas while their skeletal structure of oxea megascleres is markedly confused. They are assigned to the large genus Haliclona Grant, 1841 (family Chalinidae) in a new subgenus, Haliclona (Flagellia) subgen. nov. The species belonging to the new subgenus are reviewed and four species new to science are described, Haliclona (Flagellia) indonesiae subgen. et sp. nov., H. (F.) amirantensis subgen. et sp. nov., H. (F.) hiberniae subgen. et sp. nov. and H. (F.) hajdui subgen. et sp. nov. One species, H. (F.) hentscheli nom. nov., is given a new name on account of secondary homonymy caused by its transfer to the genus Haliclona. One species remains unnamed because of paucity of material. Already known species, reassigned to the new subgenus are H. (F.) hamata subgen. et comb. nov., H. (F.) flagellifera subgen. et comb. nov., H. (F.) porosa subgen. et comb. nov., H. (F.) edaphus subgen. et comb. nov. and H. (F.) anataria subgen. et comb. nov. Additional species are likely hiding among many erroneous records of ‘Gellius flagellifer’ from wide ranging parts of the global oceans.
Fungivorous gall midges of the subfamilies Lestremiinae, Micromyinae, Winnertziinae and Porricondylinae were largely neglected in previous inventories of the Diptera faunas of the Czech and Slovak Republics. A taxonomic-faunistic study focusing on these subfamilies identified a total of 80 species, of which 49 are new records for the Czech Republic and 33 are new records for Slovakia. Species that have never before been found in central Europe are Aprionus dalarnensis Mamaev, 1998, A. oligodactylus Jaschhof, 2009, A. pigmentalis Mamaev, 1998, Asynapta inflata Spungis, 1988, Camptomyia gigantea Spungis, 1989, Cassidoides fulviventris (Mamaev, 1964), Claspettomyia hamata (Felt, 1907), Dendrepidosis longipennis (Spungis, 1981), Dicerura dispersa Jaschhof, 2013, Divellepidosis lutescens (Spungis, 1981), D. pallescens (Panelius, 1965), D. vulgata Jaschhof, 2013, Ekmanomyia svecica Jaschhof, 2013, Holoneurus ciliatus Kieffer, 1896, Monepidosis pectinatoides Jaschhof, 2013, Neocolpodia gukasiani (Mamaev, 1990), Neurolyga acuminata Jaschhof, 2009, Neurolyga interrupta Jaschhof, 2009, Parepidosis planistylata Jaschhof, 2013, Peromyia bidentata Berest, 1988, Porricondyla errabunda Mamaev, 2001, P. microgona Jaschhof, 2013, P. tetraschistica Mamaev, 1988, Schistoneurus irregularis Mamaev, 1964, Spungisomyia fenestrata Jaschhof, 2013, S. media (Spungis, 1981), Tetraneuromyia lamellata Spungis, 1987, T. lenticularis (Spungis, 1987), and Winnertzia parvispina Jaschhof, 2013. A new genus including a single new species of Porricondylini is described and named Glossostyles perspicua Jaschhof & Sikora gen. et sp. nov. on the basis of specimens collected in the Czech Republic and Sweden. Adult morphology suggests that Glossostyles gen. nov. is a close relative of Claspettomyia Grover, 1964.
Siamopsis gen. nov., described here, belongs to a group of genera with the right valve overlapping the left valve in the subfamily Cypridopsinae Kaufmann, 1900 of the family Cyprididae Baird, 1845. The distinguishing characters of the new genus are in the morphology of its valves and soft parts. The postero-dorsal margin of the internal left valve is plate-like protruded. The morphology of this plate varies in different species, e.g., some species bear a tooth-like tubercle on the plate. The posterior margin of the right valve is recurved inwardly at ca mid-height, resulting in the occurrence of a lobe-like expansion that can clearly be seen in the dorsal and caudal views of the carapace. In addition, the other diagnostic soft part features of the new genus are the cylindrical caudal ramus, the presence of two t-setae on the female A2 penultimate segment, the very elongated terminal segment of the Mx1 palp, the morphology of the two large bristles (tooth bristles) of the Mx1 third endite (one smooth, one serrated) and the absence of d-seta on T1. In the present paper, five new species are described under this new genus: Siamopsis renateae gen. et sp. nov., S. suttajiti gen. et sp. nov., S. conspecta gen. et sp. nov., S. khoratensis gen. et sp. nov. and Siamopsis planitia gen. et sp. nov. A key to the species of Siamopsis gen. nov. is also provided.
From a moss sample collected in the Manabí Province in Ecuador, we extracted 96 specimens of a new species of eutardigrade. No eggs were found. In order to obtain eggs, an in vitro culture was prepared. In total, 136 specimens (including ten simplex), one exuvia and 44 eggs (including two with embryos) of the new species were obtained. In addition to the traditional taxonomic description with morphometrics, light and scanning microscopy imaging, we also provide nucleotide sequences of three nuclear (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial (COI) DNA fragments of the new species. Macrobiotus polypiformis sp. nov. belongs to the hufelandi group and is most similar to Ma. paulinae Stec, Smolak, Kaczmarek & Michalczyk, 2015, but differs from it mainly by the lack of dorso-lateral patches of granulation on the cuticle, egg processes with longer and more numerous filaments and in some morphometric characters of both eggs and adults. Moreover, we provide a short discussion on the modifications/abnormalities of the claws in eutardigrades and the possible consequences on the taxonomic status of Mesobiotus armatus (Pilato & Binda, 1996), suggesting its consideration as species inquirenda (with uncertain taxonomic status).
The genus Hybovalgus Kolbe, 1904 is represented by eight species on the Chinese mainland, many of which also inhabit northern Vietnam and Laos. Species of Hybovalgus are endemic to this area, and to the island of Taiwan. Until now, there is a lot of confusion in our knowledge of Hybovalgus on mainland China, due to erroneous descriptions of new species by European entomologists and incorrect identifications of specimens by local entomologists. Study of more material and many types has clarified this situation by better defining the species, synonymizing some of them, describing one new species, Hybovalgus calvus sp. nov. and recognizing the fact that females of two species were included in the new genus Excisivalgus Endrödi, 1952, which is here synonymized with Hybovalgus.
