A new genus and species of small wasp (body length, 4.3 mm, exclusive of antennae) of the extinct family Praeaulacidae (Hymenoptera: Evanioidea) is described in Burmese amber. Placement in the Praeaulacidae is based on the hind wing venation with RS, cu-a and apparent r-m present and a 10-celled forewing. Special forewing features are a large CuA cell and very narrow 3rm cell that is not aligned with 2r-m. The narrow hind wings have a unique venation with RS, M, Cu and A reaching the lower wing margin. The metasoma is attached to the propodium by a 1-segmented petiole. The ovipositor is long, exceeding the length of the metasoma. An angiosperm flower is adjacent to the wasp and the presence of herbivorous insect larvae on the flower may have attracted the female wasp.

A new genus and species of the neuropteran family Berothidae from the mid-Cretaceous Burmese amber, namely Xiaoberotha bipunctata gen. et sp. nov., is described. In addition, an undetermined species of this new genus is also described. This new genus greatly differs from most known berothids by the presence of forewing ScA and the configuration of hind wing Cu that is not approximating posterior wing margin. The new genus superficially resembles Hemerobiidae by having the distinct, posteriorly curved forewing ScA and the two forewing cua-cup crossveins that are shared by many brown lacewing genera. However, no autapomorphy of Hemerobiidae could be confirmed to be present in the new species. Here we tentatively place this new genus in Berothidae by the configuration of the female gonocoxites 8, which is conspicuous and dorsoventrally extended. This unusual beaded lacewing genus highlights the morphological diversity of the extinct Berothidae.

The Relationship

A new genus and species of the lacewing family Psychopsidae, Electropsychops handlirschi gen. et sp. nov., is described based on a well preserved male specimen from the mid-Cretaceous amber of Myanmar. The new genus possesses a number of diagnostic characters of Psychopsidae, i.e., the lack of a forewing median nygma, the presence of a vena triplica, and the straight and barely forked RA. However, it also exhibits some remarkable characters that are present in Osmylopsychopidae, such as the distally narrowed forewing costal space and the sigmoid MA stem in the hind wing. The relationship between Psychopsidae and Osmylopsychopidae is briefly discussed.

A new genus and species of the basal bethylid subfamily Holopsenellinae is described and figured from a female in Burmese amber, the first occurrence of the lineage outside of the Early Cretaceous deposits of Lebanon. Holopsenelliscus pankowskiorum gen. and sp. nov., differs from other holopsenellines most notably in the discontinuous anterior wing margin and open subdiscal cell, among other traits. The genus and species are described in full and distinguished from Holopsenella primotica Engel et al. in Lebanese amber and Cretabythus sibiricus Evans in Taimyrian amber. A key to the genera of Holopsenellinae is provided.

The Family

A new genus and species of apsilocephalid flies, Cascomixticus tubuliferous gen. et sp. nov. (Diptera: Asiloidea: Apsilocephalidae) is described from Burmese amber. Assignment to the Apsilocephalidae is based on the wing venation that is very similar to extant members of the family. The present fossil differs from known genera of this family by a long labellum bearing tactochemical papillae, a long tubular hypopharynx and a pointed labrum as well as the structure of the scape and pedicel. The long, tubular hypopharynx may have been used to obtain nectar from angiosperm flowers, however the function of the sharp-tipped labrum is unknown.

A new genus and species, Multistria orthotropagen. et sp. nov., and a new species, Dachibangus huisp. nov., of Mimarachnidae are described from the mid-Cretaceous Burmese amber. These new taxa display unique wing color patterns and extend the Mesozoic diversity of Mimarachnidae. The evolution of wing venation, phylogenetic placement of Mimarachnidae, and anti-predation defenses of this family in Burmese amber forest are briefly discussed.

New Genus And Species

A new genus and species of Sisyridae, Stictosisyrapennyi gen. et sp. n., is described from the Late Cretaceous (earliest Cenomanian/late Albian) Myanmar amber. It can be easily distinguished from other sisyrids genera by the configuration of wing venation such as forewing with four ra-rp crossveins, M forked distal to the separation of RP1, CuA pectinate and CuP simple; hind wing 1r-m long and sinuous. Besides, the newly documented spongillaflies bore distinct, irregularly distributed spots on the forewings.

Definition Of

AbstractThe definition of the family Evaniidae is revised and Cretevaniidae are synonymised with Evaniidae based on evidence derived from recently described Mesozoic taxa and a new genus and species, Lebanevania azari, described here from Lebanese amber. A fore leg with a long trochanter and a 12-segmented antenna are autapomorphies of the new genus. A large, high and wide head and a high and short mesosoma are derived characters shared with other Evaniidae. The new genus also has complete fore wing venation and lacks a tubular petiole, which are ground plan features of the Evanioidea. A cladistic analysis of fossil and extant members of the superfamily Evanioidea and notes on fossil taxa are presented.

A new genus and species of basal cyclostome Braconidae is described and figured from a male preserved in mid-Cretaceous amber from northern Myanmar.  <strong><em>Rhetinorhyssalus morticinus</em></strong> Engel, new genus and species, is interesting for its combination of primitive features such as a minute apical costal cell and anal stubs in the forewing, while lacking 2Cu in the hind wing, a putatively derived trait.  As such, the genus may represent a lineage diverging from the braconid stem subsequent to many protorhyssalines, while remaining basal relative to generalized cyclostome groups such as Rhyssalinae.  In addition, the Late Cretaceous <em>Diospilus allani</em> Brues, in Campanian Canadian amber, is transferred to <strong><em>Diorhyssalus</em></strong> Engel, new genus, and its similarity to <em>Rhetinorhyssalus</em> is discussed.  This transfer results in the new combination, <em>Diorhyssalus allani</em> (Brues).  Both genera are tentatively considered as subfamily <em>incertae sedis</em>.

Based on specimens recently collected in sediments from 2700 m depth off Mauritania (Northwest Africa; type locality) and from 2700–4400 m depth off Angola (Southwest Africa), a new genus and species, Mauretanaspis longichaeta gen. et spec. nov., is described. The new genus and species are characterized by a unique combination of characters: ventro-caudal shield covered by firmly adhering sediment, lateral margins strongly bent and merging into integument; introvert hooks tapering; eight pre-shield segments; absence of peg chaetae; exceptionally long posteriormost lateral chaetae equaling body length; posterior shield chaetae equaling shield length. A comparative table of characters for all currently recognised sternaspid genera and a key to all species with ventro-caudal shield covered by firmly adhering sediment are provided.

A new genus and species of scale insect (Hemiptera: Coccomorpha) is described from a female specimen in mid-Cretaceous Burmese (Myanmar) amber. Fossil female scales are rare and the present species, described as Paleolepidotus macrocolus gen. et sp. n., has such an unusual assortment of morphological features that it could not be assigned to any particular extant or extinct family. The small, ferruginous specimen exhibits a series of long wax pencils that extend around the body, including the head. The antennae and legs are quite long compared to other extant and extinct scale fossils. Of special interest are the protruding eyes, and a conical-triangular rostrum arising from between the forelegs; the claws with bifid apices are also unique. The ovisac contains immature stages.
