Rafaelnymphes is an extinct genus of lacewing in the family Nymphidae known from a fossil found in South America. The genus contains a single species, Rafaelnymphes cratoensis.

History and classification

When first described, R. cratoensis was known from a single fossil adult which is a compression-impression fossil preserved in layers of soft sedimentary rock. [1] Along with other well-preserved insect fossils, the R. cratoensis specimen was collected from layers of the Upper Aptian Crato Formation. The formation is composed of unweathered grey and oxidized yellow limestones, which preserved numerous insects, fish, birds and reptiles as a notable lagerstätten. The area is a preserved inland lake or one of a series of lakes, though the nature as a fresh or salt-water body is uncertain. The depth of the basin has been suggested as either shallow or fairly deep. The basin formed near the center of the supercontinent Gondwana during the early part of the diversification of flowering plants. [2] [3]

The R. cratoensis holotype specimen was preserved in the Wyoming Dinosaur Center-Crato collection when first studied. [1] The fossil was described by an international team of paleontologists led by Justine Myskowiak in a 2016 paper. The genus name is a combination of Rafael, a patronym honoring Rafael Martins-Neto who specialized in insects of the Crato Formation and nymphes, taken from the family name Nymphidae. They coined the specific epithet cratoensis in reference to the type locality the Crato Formation. [1]

R. cratoensis is one of several neuropteran species described from the Crato Formation. Other species include the nymphid Araripenymphes seldoni , [1] the ithonid Principiala incerta [4] and the kalligrammatids Makarkinia adamsi and Makarkinia kerneri . [2]

Description

The single fossil has a full body length of approximately 24.0 mm (0.94 in), and is mostly complete, being fossilized upside down with the legs upwards. The antennae, parts of the legs and the genitalia were not preserved. Additionally, details of the upper body, such as the presence of ocelli could not be determined. The head is rectangular in outline with the large compound eyes positioned on the sides. The preserved sections of the legs are slender and attached to the 6.0 mm (0.24 in) long prothorax. The 21.0 mm (0.83 in) long forewings are a dark brown coloring with area and spots that are a slightly darkener tone, possibly preserved color patterning. [1] There are small trichosors present along the apical rear edges of the forewings, and as typical for the family, nygmata are not present on any of the wings. The forewings and hindwings are preserved overlapping each other, obscuring detail of the hindwing venation. [1]

The Crato Formation is a geologic formation of Early Cretaceous (Aptian) age in northeastern Brazil's Araripe Basin. It is an important Lagerstätte for palaeontologists. The strata were laid down mostly during the Aptian age, about 113 million years ago. It thought to have been deposited in a semi-arid lacustrine wetland environment.

<span class="mw-page-title-main">Neuroptera</span> Order of insects

The insect order Neuroptera, or net-winged insects, includes the lacewings, mantisflies, antlions, and their relatives. The order consists of some 6,000 species. Neuroptera is grouped together with the Megaloptera and Raphidioptera (snakeflies) in the unranked taxon Neuropterida.

<span class="mw-page-title-main">Snakefly</span> 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. Recognisable representatives of the group first appeared during the Early Jurassic. They are a relict group, having reached their apex of diversity during the Cretaceous before undergoing substantial decline.

<span class="mw-page-title-main">Hemerobiidae</span> Family of insects

Hemerobiidae is a family of Neuropteran insects commonly known as brown lacewings, comprising about 500 species in 28 genera. Most are yellow to dark brown, but some species are green. They are small; most have forewings 4–10 mm long. These insects differ from the somewhat similar Chrysopidae not only by the usual coloring but also by the wing venation: hemerobiids differ from chrysopids in having numerous long veins and forked costal cross veins. Some genera are widespread, but most are restricted to a single biogeographical realm. Some species have reduced wings to the degree that they are flightless. Imagines (adults) of subfamily Drepanepteryginae mimic dead leaves. Hemerobiid larvae are usually less hairy than chrysopid larvae.

The Berothidae are a family of winged insects of the order Neuroptera. They are known commonly as the beaded lacewings. The family was first named by Anton Handlirsch in 1906. The family consists of 24 genera and 110 living species distributed discontinuously worldwide, mostly in tropical and subtropical regions. Numerous extinct species have also been described. Their ecology is poorly known, but in the species where larval stages have been documented, the larvae are predators of termites.

<span class="mw-page-title-main">Babinskaiidae</span> Extinct family of insects

Babinskaiidae is an extinct family of neuropterans known from the Cretaceous period. They are part of the superfamily Myrmeleontoidea. Their distinguishing characters include: "long filiform antennae, narrowly elongated wings, with features such as trichosors, and presectorial cross veins present in both wings, and absence of forewing oblique vein".
