A new occurrence of the onychochilid mollusc Pelecyogyra is reported from the late Floian Landeyran Formation (Apatokephalus incisus Biozone) in the Montagne Noire, southern France, where it is associated with the two tergomyans Carcassonnella courtessolei and Thoralispira laevis, and a mollusc indet. with a low cap-shaped shell. Flattened specimens of T. laevis in the same formation may be misinterpreted as specimens of Pelecyogyra. Morphologically the Montagne Noire specimens compare with Pelecyogyra fezouataensis from the late Tremadocian Fezouata Formation (Araneograptus murrayi Biozone) in Morocco and are tentatively referred to this species. Each occurrence of Pelecyogyra is from one or two localities only, but separated in time. They differ further in the deeper facies, association with Carcassonnella and Thoralispira, and non-gregarious occurrence in Montagne Noire compared to the shallower facies, lack of other molluscs and gregarious occurrence in the Fezouata Formation. In the Lower Ordovician, Pelecyogyra, Carcassonnella courtessolei, the rare C. vizcainoi and Thoralispira laevis are taxa that occur only in Montage Noire and the Anti-Atlas, while Lesueurilla prima also occurs in the Prague basin of the Czech Republic. Contrary to other faunal elements, like echinoderms and trilobites, these genera seem to have a wide environmental tolerance and are long ranging taxa. The main occurrence of the three key taxa Carcassonnella, Thoralispira and Lesueurilla in the Montagne Noire is in the lower part of the La Maurerie Formation (Taihungshania miqueli acme Zone), while the same taxa appear just slightly later in Morocco (?Cymatograptus protobalticus Biozone). Migration to the Anti-Atlas during the early Floian seems to have been possible during a period of general faunal exchange. Pelecyogyra may either have migrated from the Anti-Atlas to Montagne Noire during the same interval or possibly during the late Floian as indicated by shared faunal elements between these two regions at that time.

Lodevoisadia coheni gen. et sp. nov. is described as the ninth species of ‘Grylloblattodea’ from the middle Permian of the Salagou Formation, near Lodève town (France). It is currently not reasonable to place this species into a specific family, even though it seems to share most characters with the small family Tunguskapteridae. The lack of phylogenetic analysis and the current poor delineation of the majority of the grylloblattodean families (lacking synapomorphies) render any attribution of new taxa to a particular family often uncertain.

The lacustrine Konservat-Lagerstätte of Menat (Puy-de-Dôme, France) is a unique window in the terrestrial Paleocene environments of Western Europe (Wedmann et al., 2018). It has yielded an exceptional diversity of plants (leaves, flowers, seeds, pollen), and animals (vertebrates and arthropods, especially insects) (e.g., Piton, 1940). Nevertheless, flies are quite rare in this outcrop in which the paleo-entomofauna is dominated by beetles (69% of a collection of 3938 specimens). To date, this paleo-maar has given only one specimen of the family Bibionidae, a Plecia sp. (Nel, 2007). Piton (1940) also described a ‘Bibio sp.’, but Nel (2007) reexamined the two specimens of Piton, concluding that they are not bibionids. Thus, this family is clearly very rare in this outcrop. The Bibionidae seem to be quite rare in the Paleocene and early to middle Eocene outcrops of Western Europe (Oise amber, Baltic amber, Messel) (Gee et al., 2001; Nel, 2007; Skartveit & Wedmann, 2015; Skartveit, 2021). They are also rather rare in the late Eocene of the Isle of Wight (Krzemiński et al., 2019), while they are much more frequent in the younger, late Eocene, Oligocene, or Miocene paleolakes of France, Germany, and Spain (e.g., Monteils, Rott, Cereste, Dauphin, Aix-en-Provence, Rubielos de Mora, Ribesalbes, Montagne d’Andance, Sainte-Reine) (Peñalver-Molla, 1998, 2002; Skartveit & Nel, 2017; Skartveit & Wedmann, 2021). They are the most frequent insects in these outcrops.
