This new taxon is attributed to the subfamily Syntexinae because of its forewing venation (i.e., 1-Rs+M forking at 1m-cu level), but differs from all other syntexines genera because of its peculiar shape and length of 2r cell (ca. twice as long as wide, not distinctly widened apically nor basally) and by its vein 6-Rs strongly curved distally towards wing margin. The discovery of this new genus challenges the clear differentiation between Anaxyelinae and Syntexinae, prompting a thorough discussion on the diagnostic value of the wing venation characters that were previously used to distinguish the two subfamilies.

They have retained many physical characteristics over an immense period stretching from the Carboniferous to the present. Over this time they have greatly varied in size and mass, as shown in the fossil record and in particular by the length, shape, and structure of their wings. A fossil of Meganeurites gracilipes indicates that this large ‘griffenfly’ had a ‘hawker’ hunting behavior similar to certain extant species, with long periods of flight in which power, thermoregulation, and respiration would therefore tend to a ‘steady state’ equilibrium, allowing oxygen requirements and tracheole volumes to be projected and compared to extant ‘hawkers’. Comparing these values with standard pO2 models allows paleo-atmospheric density estimates to be derived. The results suggest that paleo-air pressure has varied from over two bars in the Late Carboniferous, Late Permian, and Middle to Late Jurassic, with lower values in the Early Triassic and Early Jurassic.","PeriodicalId":53179,"journal":{"name":"Palaeoentomology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49014200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amber provides not only adults, but also fossil larvae; some of these fossil neuropteriformian larvae have very unusual morphologies not seen in the modern fauna. We here report an unusual new fossil neuropteriformian larva. The mouthparts form a beak. Fossil larvae with similar mouthparts are known, and it seems that this new larva is a representative of the species ?Partisaniferus edjarzembowskii. The new larva, unlike the already known ones, has a large and inflated trunk. Based on comparison with extant larvae, such an inflated trunk should be considered physogastric. The new larva is only the second case of physogastry in fossil holometabolan larvae. Also early larvae of this species are known. The strong difference between the different larval stages give reason to interpret the ontogeny hypermetamorphic. Also this phenomenon is in fact very rare in the fossil record; most earlier candidates remain assumptions without further substantiation. Physogastry in larvae is often coupled to a mode of live in confined spaces, for a fossil preserved in amber this may mean living inside wood. Feeding mode might have been predatory, but could also have been feeding on fungi.","PeriodicalId":53179,"journal":{"name":"Palaeoentomology","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48792343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
