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 lacewing family Nemopteridae Burmeister, 1839 is very poorly represented in the fossil record with three Early Cretaceous genera of uncertain affinities from the Brazilian Crato Formation, one ‘mid’-Cretaceous representative of the stem group of the Crocinae Navás, 1910 in the Burmese amber, and two Cenozoic nemopterine genera Marquettia Navás, 1913 (late Eocene-early Oligocene) and Paleonemia Claisse et al., 2019 (middle Oligocene). Also two undetermined Nemopterinae are recorded from the late Eocene and the Oligocene (Lu et al., 2019a: Table 1; Claisse et al., 2019).

Stem Group

A new genus and species of damselfly, Burmagrion marjanmatoki, gen. et sp. nov., is described from Early Cretaceous Burmese amber. It is attributed to the basal stem group of Coenagrionoidea. The inclusion of five wings from the same species suggests that the amber piece contains the remains of a mating pair of damselflies.

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.

Female Wasp

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.

The Family

AbstractA new genus and species of the planktonic shrimp family Luciferidae,Sume marcosin. gen. n. sp., is described and illustrated from material collected in calcareous shale of the late Early Cretaceous (Aptian–Albian) Romualdo Formation, Araripe Basin, northeastern Brazil. The material is very well preserved, including the antennae, stalked eyes, second and third maxillipeds, pleopods, and uropods, and represents the first described fossil of the family Luciferidae.UUID:http://zoobank.org/fdf825b8-6fe9-42ae-8fc7-73c220eec03a

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 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.

New Discovery

Tettagalma striata, new genus and species of Tettigarctidae (Hemiptera: Cicadoidea), is described from the Lower Cretaceous laminated limestones of the Crato Formation, Brazil. The new discovery represents the first certain record of this family in Brazil and confirms its presence in the Southern Hemisphere during the early Cretaceous. Architettix Hamilton, 1990, from the same formation, and all the taxa originally placed in Cicadoprosbolidae, are also included in Tettigarctidae, as the former is considered a synonym.
