History and classification

Necroraphidia arcuata is known only from one fossil, the holotype, specimen number CES 391.1. The specimen is composed of a partial isolated fore and hind-wings, leg segments, and a partial abdomen. All of the wings and the abdomen are covered in a mat of fungal hyphae. They are included in a specimen of amber with plant debris and a number of other insects, such as coleopteras, hymenopteras. and aphids. The fossil was recovered from outcrops of the Las Peñosas Formation in Rábago, part of the Cantabria autonomous community in Northern Spain. [1] Necroraphidia was first studied by group of paleoentomologists led by Ricardo Pérez-de la Fuente of the University of Barcelona and including Enrique Peñalver, Xavier Delclòs, and Michael S. Engel. Their 2012 type description of the new genus and species was published in the electronic journal ZooKeys . [1] The genus name Necroraphidia was coined by the researchers as a combination of the snakefly genus Raphidia and the Greek nekros meaning "dead". The specific epithet arcuata is derived from the Latin arcuatus , meaning "bent", a reference to the distinct structure of the pterostigmal crossvein. [1] Necroraphidia arcuata is one of six described snakefly species found in the Albian deposits of Cantabria. [1] Necroraphidia is most similar in character to Ororaphidia and Styporaphidia , both from the Jurassic of Mongolia.

Description

The lone specimen of Necroraphidia arcuata is of a very fragmentary adult. The hyaline forewings are partially preserved and display brown vein structuring that hosts robust setae. The left forewing is the most complete, being approximately 6.9 millimetres (0.27 in) in length and a maximum of 2.7 millimetres (0.11 in) in width. The total estimated length for the forewings is less than 9 millimetres (0.35 in). Overall the legs show a striped pattern of dark and light patches. The femur has three distinct dark patches while the tibia has a darkened proximal area and a dark patch below the midpoint. [1] The abdomen is 3.7 millimetres (0.15 in) long but details of the abdomen are obscured by the dense growth of fungal hyphae and some decomposition. [1] The overall dimensions of the genus are smaller than either Ororaphidia or Styporaphidia . All three genera are noted for the pterostigmal region lacking a basal cross vein and instead being diffuse. Necroraphidia and Styporaphidia are separable by the cross veins in the pterostigma, with only one being found in Necroraphidia while Styporaphidia has two. The forewing of Ororaphidia is notably larger at 11.4 millimetres (0.45 in) and also displays distinct shapes to both the pterostigmal cross vein and second radial cell. [1]

Snakefly Order of insects

Snakeflies are a group of predatory insects comprising the order Raphidioptera with two extant families: Raphidiidae and Inocelliidae, consisting of roughly 260 species. In the past, the group had a much wider distribution than it does now; snakeflies are found in temperate regions worldwide but are absent from the tropics and the southern hemisphere. They are a relict group and have been considered living fossils, as species from the early Jurassic period closely resemble modern-day species.

Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1925.

Mesoraphidiidae Extinct family of insects

Mesoraphidiidae is an extinct family of snakeflies in the suborder Raphidiomorpha. The family lived from the Late Jurassic through the Late Cretaceous and is known from twenty-five genera. Mesoraphidiids have been found as both compression fossils and as inclusions in amber. The family was first proposed in 1925 by the Russian paleoentomologist Andrey Vasilyevich Martynov based on Upper Jurassic fossils recovered in Kazakhstan. The family was expanded in 2002 by the synonymizing of several other proposed snakefly families. The family was divided into three subfamilies and one tribe in a 2011 paper, further clarifying the relationships of the included genera.
