Palmatolepis (Palmatolepis)

Belongs within: Palmatolepis. The type subgenus of Palmatolepis includes those Famennian species in which the S3–4 elements have a reduced bipennate morphology (Donoghue 2001). The baitfish of the Late Devonian Published 13 May 2024 Towards the end of the Devonian period, the pelagic zone of the sea was dominated by Palmatolepis. Over 100 species have… Continue reading Palmatolepis (Palmatolepis)


Belongs within: Holometabola.Contains: Raphidioptera, Megaloptera, Coniopterygidae, Euneuroptera. The Neuropterida are a clade of largely predatory insects whose wings are often densely veined. Members are united by possession of a medially divided metapostnotum, the first abdominal tergum having a caudally bifid longitudinal sulcus, the fusion of the gonoplacs in the ovipositor, and a proventriculus with an… Continue reading Neuropterida


Belongs within: Neoneuroptera.Contains: Psectra, Micromus, Hemerobius. The Hemerobiidae, brown lacewings, are generally smaller lacewings that are mostly generalist predators. They are typically found on trees and shrubs (more rarely on low vegetation) and are often very cryptic, dropping and feigning death when disturbed. Larvae are active predators with short body hairs that do not carry… Continue reading Hemerobiidae


Belongs within: Euneuroptera. The Osmylidae are a diverse group of moderate-sized to large lacewings that typically have camouflaging patterns on their wings. Larvae are long and slender with elongate, lance-like jaws and are most commonly found in moist riparian habitats. Some members of the clade Osmylomorpha have larvae living in drier locations (Engel et al.… Continue reading Osmylidae


Belongs within: Neoneuroptera.Contains: Nemopteridae, Ascalaphidae, Myrmeleontidae, Prohemerobiidae, Kalligrammatidae. The Myrmeleontiformia are a lineage of lacewings including the ant-lions, owlflies and related taxa, united by the presence in larvae of a modified prementum resembling a labial palp segment, and by features of the adult genitalia (Grimaldi & Engel 2005). Members include the Psychopsidae, broad-winged lacewings found… Continue reading Myrmeleontiformia


Belongs within: Neuropterida. The Coniopterygidae, dustywings, are a group of minute lacewings, generally with wingspans less than 7 mm, and with reduced wing venation and a dense covering of a waxy or mealy secretion (Grimaldi & Engel 2005). The wings are coupled by hamuli though the hind wings may occasionally be reduced (New 1991). Larvae… Continue reading Coniopterygidae


Belongs within: Neuropterida. The Megaloptera, alderflies and dobsonflies, are a group of long-winged insects with aquatic predatory larvae. Recent species are divided between the families Sialidae and Corydalidae; Corydalidae have three ocelli and simple tarsi whereas Sialidae lack ocelli and have the fourth tarsal segment prominently bilobed. Males of some Corydalidae have the mandibles enormously… Continue reading Megaloptera


Belongs within: Myrmeleontiformia.Contains: Cymothales, Protoplectrini, Myrmeleontini, Distoleontini, Periclystina, Dendroleontina. The Myrmeleontidae, ant-lions, are a group of lacewings found in arid and semi-arid regions, best known for the conical pits built by the larvae of many species. The larva lies buried in the base of its pit, feeding on any insects that fall in. Most myrmeleontids… Continue reading Myrmeleontidae


Belongs within: Eumalacostraca.Contains: Squillidae, Gonodactyloidea, Lysiosquillidae. The Hoplocarida, including the mantis shrimps and their fossil relatives, are a group of malacostracan crustaceans bearing a small carapace and at least four free thoracic segments, together with a large abdomen ending in a tail fan. They differ from other living crustaceans in being active, rapacious hunters (Schram… Continue reading Hoplocarida


Belongs within: Podogennonta. The Diosaccinae: worldwide sediment dwellers Published 16 May 2021 The harpacticoid copepods have been featured on this site a reasonable number of times now. These tiny crustaceans are among the most numerous animals in the world, both in terms of numbers of individuals and (in certain habitats) numbers of species. And among… Continue reading Diosaccinae
