A new genus and species of burrower bug, Chilamnestocoris mixtus gen. et sp. nov. (Hemiptera: Cydnidae), is described from Upper Cretaceous Myanmar amber. The new genus is characterized by a very long claval commissure and, therefore, is classified within the extant subfamily Amnestinae. It presents a mixture of generic characters relevant to the genus Chilocoris Mayr (Cydninae) and the genus Amnestus Dallas (Amnestinae), but also has its own autapomorphies, i.e., each cephalic marginal setigerous puncture arises from its own well-developed tubercle, and the middle and posterior tibiae are strongly compressed and flattened.

Aldebarania arenitea (Astropectinidae; Asteroidea; Echinodermata) is described from the Rocky Point Member of the Maastrichtian (Upper Cretaceous) Peedee Formation of North Carolina. A turbulent, shallow-water environment is suggested by sedimentary features, a diverse marine fauna, and the morphology of Aldebarania. Aldebarania appears to be a partial ecological equivalent of living Astropecten and Luidia; however, phylogenetic relationships within the Astropectinidae are unstudied and the origin of similarities is unknown.

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.

Two new genera and species are added to the fauna of dustywings (Coniopterygidae) preserved in Upper Cretaceous (earliest Cenomanian) amber of northern Myanmar, doubling the described diversity from this deposit.  One genus is of the subfamily Aleuropteryginae and described as Achlyoconis heptatrichia Engel, new genus and species.  This species is noteworthy for the infumate and patterned wings and unique presence of seven prominent setae positioned on thickenings occurring along the length of the forewing media.  Paranimboa litotes Engel, new genus and species, is representative of the subfamily Coniopteryginae and distinctive among Mesozoic groups for the unbranched Rs, among other traits.  In addition, a peculiar larva preserved alongside the holotype of P. litotes is described.  While having a prothoracic and head form similar to aleuropterygines as well as a labial palpus with only two palpomeres, diagnostic for Coniopterygidae, the antenna bears four articles rather than the two present in crown-group dustywings.  A revised key to the genera of Cretaceous Coniopterygidae is provided.

Abstract Burmese amber is well known for preserving unique extinct lineages of insects. Here, we describe a new fossil beetle in its larval stage from Burmese amber. Bayesian and parsimony phylogenetic analysis of 50 morphological characters support this fossil as being sister to both the tribes Dineutini and Orectochilini, representing an extinct stem lineage in Gyrininae. It is described here as a new genus and species of whirligig beetle, Chimerogyrus gigagalea gen. & sp. nov., a taxon that preserves remarkable intermediate features between the whirligig beetle tribe Gyrinini and the crown Orectochilini and Dineutini. This new taxon preserves key features for studying the evolution of characters within the larval stage of the Gyrinidae and highlights the importance of Burmese amber for preserving both stem and crown lineages present during the mid-Cretaceous, before the end-Cretaceous mass extinction event.

A new genus and species of the extinct family Weitschatidae, Criniverticillus longicumulus gen. et sp. nov. (Hemiptera: Coccomorpha), is described and illustrated from mid-Cretaceous Burmese amber. The new species is based on a fossil specimen with complete body, wings and antennae. The family diagnosis is updated to include similarities between Criniverticillus, Pseudoweitschatus and Weitschatus. An identification key to species of Weitschatidae is provided.
