A new genus and species of Hypselosomatinae (Heteroptera: Dipsocoromorpha), Hypsotsijilia bretoni Cifuentes-Ruiz and Brailovsky gen. nov., sp. nov. is herein described based on a female specimen. It represents the first fossil record of Schizopteridae in the early Miocene amber from Chiapas, Mexico. It is compared with related taxa and the estuarine paleoenvironment is discussed, matching the one previously cited for the subfamily in other estuarine amber deposits.

Burmese Amber

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 Species

The early Miocene site of Wadi Moghra, Qattara Depression, Egypt, is important for interpreting anthracothere (Mammalia, Artiodactyla) evolution, because the Moghra sediments preserve a higher diversity of anthracotheres than any other pene-contemporaneous site. New specimens from Moghra are described and form the basis for the systematic revision of Moghra anthracotheres provided here. Among the important discoveries recently made at Moghra is the first complete skull of Sivameryx moneyi. Other new specimens described here include two new species of Afromeryx, and a new genus and species, all of which are unique to Moghra. A review of biogeographic information supports the conclusion that three of the Moghra anthracotheres (Brachyodus depereti, B. mogharensis, and Jaggermeryx naida, n. gen. n. sp.) are members of late surviving lineages with a long history in Africa, while three other species (Afromeryx grex, n. sp., A. palustris, n. sp., and Sivameryx moneyi) represent more recent immigrants from Eurasia.

New Genus And Species

A new genus and species Allorapisma chuorum gen. sp. nov. is described from the Early Eocene locality at Republic, Washington, U.S.A. The forewing venation of Allorapisma is most similar to that of the genus Principiala Makarkin & Menon from the Early Cretaceous of Brazil and Britain. A new, informal suprageneric taxon consisting of these genera is proposed, the Principiala group. The habitats of extant and fossil Ithonidae are briefly discussed.

Fossil Fish

Four specimens of a small fossil fish were collected from the Eocene Mahenge site of Tanzania. The specimens, preserved as part and counterpart natural moulds, are identified, predominantly based on the structure of the caudal skeleton, as members of the Characiformes, probably the sister group to the living African Alestidae. The area just behind the skull, in the two specimens that include this area, is distorted, and therefore it is difficult to identify the bones of the Weberian apparatus, although that structure does appear to be present. The fossil record of characiforms includes few articulated skeletons, with only one other African species previously reported from much younger deposits. The new specimens from Mahenge are described here as a new genus and species, Mahengecharax carrolli.

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).

Felid Species

ABSTRACTA new genus and species of felid, Ginsburgsmilus napakensis, is described from Napak, Uganda. Material from Songhor, Kenya, previously identified as Afrosmilus turkanae by Schmidt-Kittler (1987) is assigned to this species. A new species of Afrosmilus, A. hispanicus, is described from Artesilla, Spain. These new felid species combine sabre-tooth canines of maochairodont type with cheek teeth similar to those of Pseudailurus. Phylogenetically they are close to Afrosmilus turkanae which shows a greater specialisation towards markedly machairodont forms. On the basis of dental features, we propose a close relationship between these two genera (which we group into the new tribe Afrosmilini) and the tribe Barbourofelini (Sansanosmilus and Barbourofelis), the transition between the two being represented in the fossil record by Prosansanosmilus peregrinus Heizmann et al. 1980.

A New Species

The genus Astrophiura, which ranks among the most extraordinary of modern brittle stars, is the type genus of the recently resurrected family Astrophiuridae within the order Ophiurida. On account of its absurdly enlarged and strongly modified lateral arm plates, Astrophiura bears a closer resemblance to a pentagonal starfish than to a typical ophiuroid. Although molecular evidence suggests an ancient origin of the Astrophiuridae, dating back at least to the Early Jurassic, not a single fossil astrophiurid has been reported so far. Here, we describe dissociated lateral arm plates from the Campanian of Cringleford near Norwich, UK, and the Maastrichtian of Rügen, Germany (both Upper Cretaceous) with unambiguous astrophiurid affinities and assign these to a new species, Astrophiura markbeneckei. This represents the first fossil record of the family. In addition, the Rügen material included lateral arm plates that superficially resemble those of A. markbeneckei sp. nov. but differ in having spine articulations that are typical of the ophionereidoid family Amphilimnidae. We assign these plates to a new genus and species, Astrosombra rammsteinensis, an extinct amphilimnid with morphological modifications similar to those of Astrophiura, and thus representing a remarkable case of parallel evolution amongst brittle stars looking like starfish.

Based on a well-preserved female specimen, a new stonefly genus and species of the family Taeniopterygidae, Balticopteryx dui gen. et sp. nov. is described and illustrated, which is also the first report of subfamily Brachypterainae from the Eocene Baltic amber. Diagnostic characters of this new genus are discussed and compared with related taxa.

With over 4,600 species distributed worldwide, the net-winged beetles belong among the most speciose elateroid lineages. Despite this, beetles of the family Lycidae are rare in the fossil record. A new genus and species of Lycidae, Cretolycus praecursor gen. et sp. nov., is herein described based on a single specimen preserved in mid-Cretaceous Burmese amber. Cretolycus praecursor represents the second known lycid from the Mesozoic. A new tribe, Cretolycini trib. nov., is erected for the species, characterised by 11-segmented filiform antennae, 3-segmented labial palpi with an enlarged apical palpomere, and elytra without costae. A catalogue of fossil net-winged beetles is appended.
