The discovery of asellotan isopod species resembling Stenetrium, but with male pleopods like those in the genus Pseudojanira Barnard, 1925 necessitated a re-examination of the taxonomy of the family Pseudojaniridae Wilson, 1986. Data presented in this paper support the assignment of the Pseudojaniridae to the superfamily Stenetrioidea Hansen, 1905, thus eliminating the superfamily Pseudojaniroidea Wilson. A new definition of the Stenetrioidea and a generic key are provided. The genus Pseudojanira and its species are revised, including a species-level key. A study of Pseudojanira investigatoris Poore and Just, 1990 has revealed two new cryptic species, Pseudojanira fremantlensis, sp. nov. and Pseudojanira justi, sp. nov. Some paratypes and other specimens originally classified as Pseudojanira investigatoris are reassigned to other species. Descriptions of two new monotypic genera of the Pseudojaniridae, Schottea taupoensis, gen. nov., sp. nov. andAdajinoperus tetanomorphus, gen. nov., sp. nov. further expand the recognised morphological diversity of this family. A new genus of Stenetriidae, Lexcenium, gen. nov., with two new species, L. poorei, sp. nov. and L. greenensis, sp. nov., provides additional evidence of the diverse, non- homologous forms of the ‘stylet-like’ appendix masculina within the superfamily.

A New Species

1. A new species of Bothriocephalus—B. pycnomerus—is described from the intestine of Ophiocephalus marulius Ham. Buch., from the Ganges and Jumna at Allahabad, India.2. B. pycnomerus closely resembles B. histiophorus (Shipley 1901; from the marine sword-fish Histiophorus) in structure but differs chiefly in the possession of an armed scolex and its crowded indistinct segmentation.3. Lühe's definition of the genus Bothriocephalus must be amended to include forms with armed scolices and forms in which the ventral uterine apertures are a-median and irregularly alternate.4. Two new species of Proteocephalidae are described which possess armed muscular rostella, and for these a new genus Gangesia is created and defined. The definitions of the Order Tetraphyllidea (Lühe 1910) and of the Family Proteocephalidae (La Rue 1914) must be amended to include forms possessing muscular rostella, armed or unarmed.5. These two new species—Gangesia wallago and G. macrones—were found in the intestines of Wallago attu Bleek and Macrones seenghala Sykes (both Siluroids) respectively, from the Ganges and Jumna at Allahabad.6. Southwell's “Ophryocotyle bengalensis,” from Ophiocephalus striatus, Labeo rohita and Wallago attu, is probably identical with Gangesia wallago.

Gimmel et al. (2019) recently treated the two fossil taxa of the beetle family Cyclaxyridae (Cucujoidea), a family that is today represented only by two species in New Zealand (Gimmel et al. 2009). Gimmel et al. (2019) synonymized two species from European amber described within the family Phalacridae (Cucujoidea), Stilbus bedovoyi Lyubarsky & Perkovsky, 2011 and Neolitochropus hoffeinsorum Lyubarsky & Perkovsky, 2016, with Neolitochropus bedovoyi (Lyubarsky & Perkovsky, 2011) becoming the valid combination. They treated a total of 13 specimens of this species from across Rovno, Bitterfeld, and Baltic amber deposits, implying a widespread and abundant species in Eocene Europe whose life history, like extant forms, was likely tied to sooty molds (Gimmel et al. 2019).

Abstract Describes ammonites belonging to the family Tulitidae from Bathonian (Jurassic) localities of France. Specimens formerly attributed to Ammonites microstoma are assigned to the new genus Treptoceras, with two new species T. laurenti and T. crimaciense A complete specimen of Schwandorfia marginata is also described. The genera Sphaeroptychius, Schwandorfia, and Treptoceras are considered diagnostic of the middle and upper Bathonian.

A new genus Mirabythus Cai, Shih et Ren, gen. nov. (type species, M. lechrius Cai, Shih et Ren, sp. nov.) and M. liae Cai, Shih et Ren, sp. nov. from the family Scolebythidae are described from the Early Cretaceous Yixian Formation of Huangbanjigou Village, Liaoning Province, northeastern China. These findings extend the existence of Scolebythidae to the Early Cretaceous of China, while providing evidence to support Engel and Grimaldi’s hypothesis that the family was widely distributed throughout the Cretaceous. Our two new species with clear venation also provide a comprehensive understanding of the venational changes from the Early Cretaceous to now. A key to the fossil and extant genera of Scolebythidae is provided.

Baetidae is one of the most diverse families of Ephemeroptera. In South America this family now encompasses 27 genera and more than 130 species. The Guyana region is known for its extraordinary diversity and high level of endemism, which is, above all, remarkable at the tops of the isolated flat-topped table mountains – tepuis. Recently various international speleological expeditions to Churí-tepui explored the cave systems of this mountain. Here we describe a new genus of Baetidae recently found during the mentioned expeditions to Churí-tepui and Auyán-tepui. Parakari n. gen. can be distinguish from the other genera of this family, among other characters, in the nymphs by the absence of abdominal gills I, tarsal claws with subapical denticle larger than the others, right mandible with prostheca bifid and pectinate and with incisors positioned in obtuse angle to mola area, lingua with a tuft of setae, segment II of maxillary palpi with a concavity and a hole apically and segment II of labial palpi with a strong distomedial projection. In the adults the hind wings are absent and genitalia with segment II of forceps with a constriction, segment III elongate and long. Two new species are included in this genus; each one was collected at different tepui. A key and illustrations are included.

The varying concepts of Janirellidae Menzies, 1956 are outlined, including its rejection by several authors. The view of Wilson and Wägele of Janirellidae being a valid family comprising Janirella Bonnier, 1896 and presumably Dactylostylis Richardson, 1911 (= Spinianirella Menzies, 1962) is accepted. Diagnoses of the Janirellidae subsequent to Menzies’ original one were based on the inclusion of a diverse range of genera now recognised as not belonging in that family. A new diagnosis of Janirellidae is presented based on the inclusion of Janirella, Dactylostylis, and a new genus Triaina with two new species, T. isodonte and T. makridonte, from south-eastern Australia. The latter species represents the shallowest record (80 m) of the otherwise predominantly deep-water family. All species in the family are listed in an appendix, with area of type locality and depth range.

Solenogastres are a small class of vermiform Mollusca that present a mantle with calcareous sclerites and a ventral pedal groove. During the expedition Me48/1 DIVA 1, carried out in the abyssal Angola Basin between 5100-5500 m depth, several specimens of Solenogastres were collected. Their study has made possible to describe two new species and a new genus of the family Acanthomeniidae Salvini-Plawen, 1978, whose anatomical features have caused the modification of the family definition.
