Based on the geographic distribution database of the Orthoptera Species File, the diversity and distribution of the superfamily Grylloidea in the Nearctic region was studied using the statistics and Sorensen dissimilarity coefficient. A total of 164 species or subspecies belonging to 4 families, 9 subfamilies and 27 genera were recorded from this region; among which Gryllidae (93, 56.70%), followed by Trigonidiidae (44, 26.83%), Mogoplistidae (25, 15.24%), and Phalangopsidae (2, 1.22%). The diversity exhibits an asymmetric distribution pattern, with the southeastern coastal plain, the Interior Plateau and Piedmont of the United States was the most abundant. At the same time, the regional similarity of species distribution was analyzed, and the Nearctic was divided into four subregions: Boreal & Arctic zone of North America, Eastern temperate North America, Northeast temperate North America, and Southern North America & western temperate North America.

Twenty-four fossil gall midges (Cecidomyiidae) described from 1917–2020 from Mesozoic deposits, mostly ambers, are reviewed. Information from the original publications is used as the basis for reinterpretation, when such is regarded as appropriate here. As a result, the fossil record of cecidomyiids from the Mesozoic comprises representatives of the following subfamilies and tribes, all mycophagous (numbers in parentheses refer to species described): Catotrichinae (1); Micromyinae: Catochini (2), Amediini (1), Campylomyzini (1), Micromyini (2) and Aprionini (1); Winnertziinae: Heteropezini (2), Diallactiini (4) and Winnertziini (1); Porricondylinae: Dicerurini (1). Other Winnertziinae (3) and Micromyinae (5) cannot be classified to tribe because information on critical morphological structures is unavailable; they are thus considered incertae sedis. Members of the Lestremiinae sensu stricto are unrecorded from the Mesozoic, as are any Cecidomyiinae (the only subfamily containing phytophages and predators). Commonly occurring reasons for misinterpretation of amber fossils are the non-recognition of artefacts and the unfamiliarity with group-specific literature regarding prevailing taxonomic concepts and the morphological diversity found in Cecidomyiidae. These causes as well as obvious differences between neontological and paleontological taxonomic practices are discussed. Amediini trib. nov. Jaschhof, 2021 is introduced as a new tribe of the Micromyinae, to absorb the genera Amedia Jaschhof, 1997 (extant, North America, type genus), Amediella Jaschhof, 2003 (extant, New Zealand) and Eltxo Arillo & Nel, 2000 (extinct, Alava amber). A diagnosis of the new tribe is given. Krassiloviolini Fedotova & Perkovsky, 2017 is a new junior synonym of Heteropezini Schiner, 1868. Amediini Plakidas, 2017 and Zarqacecidomyius singularis Kaddumi, 2007 are nomina nuda.

Seven new species of Graphidaceae are described from the Coastal Plain of southeastern North America: Acanthothecis floridana (Florida, USA), A. leucoxanthoides (North Carolina, USA), A. paucispora (North Carolina, USA), Fissurina alligatorensis (Florida and North Carolina, USA), F. americana (Florida and Georgia, USA), F. ilicicola (Florida and Georgia, USA), and Phaeographis oricola (North Carolina, USA). The ecology and distribution of each species is discussed in the broader context of the imminent need for effective conservation and management strategies to maintain the lichen biodiversity in the region. Color illustrations of all species are provided, as are keys to the genera Acanthothecis and Fissurina in North America north of Mexico.

Taxonomic Framework

Abstract Orthotrichum lyellii was described in 1878 based on the crisped leaves with plane margins on its elongated and branched stems, and on the presence of brood-bodies. In Europe, these characters remain constant, but in North America several similar forms lacking propagules have been described either at the specific or infraspecific level. These were all reduced to synonyms of O. lyellii. In 2015, Orthotrichum was divided, and O. lyellii was transferred to Pulvigera, a genus thus far considered to be monospecific. In this study, the variability of P. lyellii is analysed in an integrative taxonomic framework. Morphological studies on > 200 specimens, including the nomenclatural types of the taxa previously described, were combined with biogeographical and ecological evidence and with a phylogenetic reconstruction of 39 terminals based on five molecular loci. All the sources of evidence suggest the existence of four different taxa in North America, one also present on the Marquesas Islands. The study of type materials led to their identification as P. lyellii and three other taxa previously described from North America, Orthotrichum papillosum, O. lyellii var. howei and O. pringlei. These taxa differ from each other in taxonomically significant morphological characters of the gametophyte and sporophyte. The morphological diversity has led us to reinterpret Pulvigera, and to amend its description. Nomenclatural changes for the reinstated taxa are proposed, and full descriptions and an identification key for Pulvigera spp. in North America are provided.

Three new species of Lumbriculidae from southeastern North America are attributed to Eclipidrilus Eisen. All are small worms (diameter 0.2–0.5 mm), having semi-prosoporous male ducts with the atria in X, and spermathecae in IX. Eclipidrilus breviatriatus n. sp. and E. microthecus n. sp. have crosshatched atrial musculature, similar to some E. (Eclipidrilus) species, but they differ from congeners in having small, compact spermathecal ampullae. Eclipidrilus macphersonae n. sp. has a single, median atrium and spermatheca. The new species have been collected only in Sandhills and Middle Atlantic Coastal Plain streams of North Carolina.
