High Diversity

The microgastropod family Triphoridae is one of the five most diverse marine molluscan families. It likely hosts a few thousand species worldwide, but its taxonomy has long been considered challenging due to the high diversity and subtle morphological characters needed for species delimitation. Consequently, only a small portion of the species appears to be formally described to date. However, further taxonomic work should be based on robust knowledge on the numerous names introduced so far. In this perspective, we have here compiled a list of all published names that can be attributed to the fossil and extant Triphoridae. We list 958 species and 75 genus names, of which 771 are known as extant species and 146 as fossil species, 41 are known from both fossil and extant records. We provide information on type locality and horizon, type material, synonymy and homonymy. Importantly, based on the review of hundreds of publications, we provide a preliminary overview of the geographic and stratigraphic distribution.

The Family

The flat wasps, Bethylidae, are cosmopolitan and one of the most diverse families of Chrysidoidea. Bethylidae have 2,920 described extant species and almost 90 fossil species. The oldest geological record of the family is the Lower Cretaceous, from Lebanese and Spanish ambers and Transbaikalian rock fossils. Here we describe and illustrate one new fossil subfamily of Bethylidae: †Elektroepyrinae subfam. nov. represented by †Elektroepyris Perrichot & Nel from the lowermost Eocene Oise amber (France), which was cladistically assessed against all other eight subfamilies of Bethylidae. The new taxon is easily distinguished from other subfamilies by the forewing venation with the third abscissa of Cu present. Phylogenetic analyses support the monophyly of all subfamilies of Bethylidae, with a matrix with 69 morphological characters and 22 terminal taxa from where †Elektroepyrinae subfam. nov. emerged as independent lineage from all other subfamilies.

Subjective Synonym

Abstract Bryozoans with calcified frontal shields formed by the fusion of costae, collectively constituting a spinocyst, are traditionally assigned to the family Cribrilinidae. Today, this family is regarded as nonmonophyletic. In the Argentine Cenozoic, cribrilinids were until recently represented by only two fossil species from the Paleocene of Patagonia. This study describes the first fossil representatives of Jolietina and Parafigularia: J. victoria n. sp. and P. pigafettai n. sp., respectively. A fossil species of Figularia, F. elcanoi n. sp., is also described. The material comes from the early Miocene of the Monte León and Chenque formations (Patagonia, Argentina). For comparison, we also provide redescriptions of the remaining extant species of Jolietina: J. latimarginata (Busk, 1884) and J. pulchra Canu and Bassler, 1928a. The systematic position of some species previously assigned to Figularia is here discussed. Costafigularia n. gen. is erected, with Figularia pulcherrima Tilbrook, Hayward, and Gordon, 2001 as type species. Two species previously assigned to Figularia are here transferred to Costafigularia, resulting in C. jucunda n. comb. and C. tahitiensis n. comb. One species of Figularia is reassigned to Vitrimurella, resulting in V. ampla n. comb. The family Vitrimurellidae is here reassigned to the superfamily Cribrilinoidea. The subgenus Juxtacribrilina is elevated to genus rank. Inferusia is regarded as a subjective synonym of Parafigularia. Parafigularia darwini Moyano, 2011 is synonymized with I. taylori Kuklinski and Barnes, 2009, resulting in Parafigularia taylori n. comb. Morphological data suggest that these genera comprise different lineages, and a discussion on the disparities among cribrilinid (sensu lato) spinocysts is provided.

In The Wild

Based on critical observations on herbarium specimens (including type material) and living plants in the wild from its type locality, we demonstrate that Thalictrum kangdingense, recently described from Kangding county in western Sichuan province, China, is readily distinguishable from T. xinningense by an array of morphological characters but is actually conspecific with T. megalostigma, a species with its type locality also in Kangding. We therefore reduce T. kangdingense to the synonymy of T. megalostigma herein. The morphological distinction between T. baicalense and T. megalostigma is also clarified.

Abstract Pseudechiniscus, the second-largest genus of the family Echiniscidae (Tardigrada: Heterotardigrada: Echiniscoidea), is notoriously difficult for taxonomic studies. In this study, I performed a morphological analysis of a new species from Croatia, based on a light microscopic and scanning electron microscopic examination of 45 specimens from the same sample. Furthermore, I have summarized all available data on Pseudechiniscus species, including their original descriptions, and have analysed the following complexes of morphological characters: (1) arrangement and morphology of dorsal cuticular plates, (2) ventral sculpture, (3) morphology of cephalic, trunk and leg sensory organs and (4) claw morphology. The applicability of these characters in the taxonomy and their distribution in the genus are discussed. Some of the characters traditionally used for species delimitation were shown to be unsuitable and others in need of a thorough reinvestigation. The meaning of the old term ‘faceted’, commonly used but often misapplied, has been clarified, based on the initial definition. Several characters of the claw structure were suggested as potentially useful for species delimitation. The taxonomic status of several old forms and species was discussed.

A New Species

AbstractThe family Peradeniidae (Hymenoptera: Proctotrupoidea) is represented by two rare extant species from southeastern Australia (Australian Capital Territory, Victoria, Tasmania). A new species, Peradenia galerita sp. n., is described from Eocene Baltic amber. The fossil species is very similar to the living Perndenia, but has the short metasomatic petiole typical of most Proctotrupoidea. The subfamily classification of Heloridae proposed by Rasnitsyn and the status of Peradeniidae are briefly reviewed. The subfamily Mesohelorinae Rasnitsyn, 1990 is a junior synonym of Protohelorinae Rasnitsyn, 1980 (syn. n.).

Single Genus

The family Corethrellidae, called frog-biting midges, with the single genus Corethrella Coquillett, 1902, is a small group of dipterans including 107 extant species (Borkent, 2017). Females of most species are haematophagous and feed on males of frogs and toads locating them by their calls (Borkent, 2008). Extant frog-biting midges have a pantropical distribution, absent in Europe, north Africa, middle and northern Asia (Giłka & Szadziewski, 2009). The genus during its phylogenetic history dated back to Lower Cretaceous (125–129 Ma) had a broader geographical distribution, and during Eocene was present in Europe. Till now nine fossil species have been described from Lower Cretaceous Lebanese amber (1), mid-Cretaceous Burmese amber (1), Eocene Baltic amber (5) and Miocene Dominican amber (2) (a complete annotated list is provided below).

Although the family Kateretidae has fewer than 100 described extant species, its fossil record is growing. The description given here of Electrumeretes birmanicus gen. et sp. nov. and Polliniretes penalveri gen. et sp. nov. brings the number of fossil species in Kateretidae up to nine. Eight of the fossil species have been described from amber deposits and six are from the Cretaceous. All the Cretaceous fossil species and one from the Eocene share atypically short elytra and three dorsally exposed abdominal tergites, whereas in Recent relatives, even though they have shortened elytra, only the pygidium and a part of the preceding one or two abdominal tergites are exposed. It is suggested that shortened elytra (brachelytry) represents an ancestral state and that elytra may have become secondary longer in extant relatives.

AbstractThe genus Anonchus is revised. The genera Assia and Haconnus are considered to be synonymous with Anonchus on the basis of the morphological analysis. Additional descriptions of six species, viz. A. maculatus , A. mirabilis , A. millelacunatus , A. palaeotropicus , A. coomansi and A. pulcher are provided on the basis of type material or recently collected populations. The lectotype of A. monohystera is designated and described and the synonymy of this species with A. maculatus is confirmed. Two new species are described; A. winiszewskae sp. n. from Paraguay and A. venezolanus sp. n. from Venezuela. Several aspects of the morphology are described and the variability and diagnostic significance of the main morphological characters discussed. A study of intrageneric and suprageneric taxonomy of the genus Anonchus is presented. The subfamily Aphanolaiminae is reinstated for the genera Aphanolaimus, Aphanonchus and Paraphanolaimus and raised to family rank. The family Aphanolaimidae includes two subfamilies: Aphanolaiminae and Anonchinae. An emended diagnosis and a revised classification of Anonchus are proposed and a key to the species of the genus is provided.

The genus Conocrinus d’Orbigny, 1850 (Crinoidea, Bourgueticrinina) was established on the basis of two aboral cups that had previously been described as Bourgueticrinus thorenti d’Archiac, 1846. One of these (now considered lost) came from the “Rocher du Goulet” at the base of the Biarritz section (Bartonian, Côte des Basques, southwest France). D’Archiac figured only the second cup; this belongs to the d’Orbigny Collection and is still housed in the palaeontological collection of the Muséum national d’Histoire naturelle (Paris) as the lectotype of the species, C. thorenti. It appears that it was collected from Priabonian levels exposed near Castellane (Alpes de Haute Provence, southeast France). New observations on this cup, as well as a detailed study of the characters of aboral cups, columnals and proximal brachials in a few extant and fossil species classically attributed to Conocrinus or to closely related genera such as Democrinus, Rhizocrinus and Tormocrinus, have yielded arguments for a revision of the taxonomy and interrelationships of extant and fossil taxa in the family Bourgueticrinidae. Conocrinus (= Tormocrinus), as here interpreted, includes six Eocene species: C. thorenti, C. archiaci, C. cahuzaci n. sp., C. duperrieri, C. cf. suessi and C. veronensis. Numerous extinct species previously attributed to Conocrinus or Democrinus are here transferred to two new genera which first occur in the lower Paleocene: Paraconocrinus n. gen. (type species: P. pyriformis) and Pseudoconocrinus n. gen. (type species: P. doncieuxi). Aboral cups from the “Rocher du Goulet” (Biarritz) are here assigned to Paraconocrinus pellati n. gen., n. sp., while the Danian species Democrinus maximus is transferred to Pseudoconocrinus n. gen. A new genus, Cherbonniericrinus, is created to accommodate a single extant species, Ch. cherbonnieri, previously attributed to Conocrinus, while the extant genus Rhizocrinus, closely related to Democrinus, is resurrected. Conocrinus and closely related genera are derived from a bourgueticrinine lineage the first record of which is from the lower Campanian, with the new genus Carstenicrinus. These are all attributed to the family Rhizocrinidae which is here considered distinct from the family Bourgueticrinidae. Rhizocrinids rapidly diversified immediately after the Cretaceous-Paleogene (K/Pg) event. Cretaceous taxa previously placed within the family Bourgueticrinidae now appear to be polyphyletic. Some of them do not belong to Bourgueticrinina, such as those of the Dunnicrinus lineage. Interrelationships of Rhizocrinidae and other post-Palaeozoic families having a xenomorphic stalk are discussed.
