Shcherbakov (1984) placed Ipsviciidae in the Scytinopteroidea and demonstrated that this superfamily is ancestral to Heteroptera (Shcherbakov, 1996). The family comprises several genera known from the Triassic and Lower Jurassic of Australia and Eurasia (Lambkin, 2020). A peculiar monotypic genus of Ipsviciidae with a strigil (stridulatory area) on the underside of the tegmen is described below from the Middle to Upper Triassic (Ladinian–Carnian) of the Madygen Lagerstätte, Central Asia. Such a strigil indicates that the new species possessed a stridulatory device of the forewing-hindleg type, similar to those occurring in the extinct Dysmorphoptilidae (Evans, 1961) and some extant true bugs (see Discussion). Dysmorphoptilids and the new ipsviciid genus may have used these devices to produce alarm signals.</p> DMITRY E.

This new genus is diagnosed by the occipital carina extending to the lower half of the head, the pronotum lacking an epomia, the pterostigma short, the petiole open but very short, the ovipositor wide and bent throughout, with its apex widely rounded. Diagnostic characters of Disogmini are revised.</p> ALEXANDR P. RASNITSYN, VIKTOR A. KOLYADA, DMITRY D.

Despite the tectonic history of India, limited connections have been found between the Cambay palaeofauna and present-day Madagascan and mainland African faunas. Here, I describe a new fossil pselaphine rove beetle (Staphylinidae: Pselaphinae) recovered from the Cambay deposit that shows closest apparent phylogenetic affinity to modern Afrotropical genera. <em>Yprezethinus grimaldii</em> <strong>gen. et sp. nov.</strong> is placed in Bythinoplectini, subtribe Bythinoplectina. Based on antennal and maxillary palp morphology, <em>Yprezethinus </em>is a putative transitional stem lineage of the <em>Zethinus</em>-group of genera—an extant clade distributed across equatorial African rainforests. Although <em>Yprezethinus</em> shares with this clade the derived feature of ovoid antennal clubs formed by tight appression of the apical two segments, it differs from its putative extant relatives in its possession of the plesiomorphic complement of 11 antennomeres, without any fusions of segments. The fossil taxon signifies a biotic link between early Eocene India and continental Africa, and marks the Cenozoic emergence of a tropical leaf litter arthropod fauna approaching that of contemporary, ant-dominated rainforests.</p> JOSEPH PARKER Copyright (c) 2022 Magnolia press limited https://www.mapress.com/pe/article/view/palaeoentomology.5.5.6 Thu, 22 Sep 2022 00:00:00 +1200 <p><strong>A review of the Cretaceous genus <em>Eltxo</em> (Diptera: Cecidomyiidae) with description of the new species <em>Eltxo</em> grimaldii from El Soplao amber</strong></p> https://www.mapress.com/pe/article/view/palaeoentomology.5.5.7 <p>A new species, <em>Eltxo grimaldii</em><strong> sp. nov.</strong>, is described from Spanish Lower Cretaceous (middle Albian) amber from El Soplao, based on a single female. The new species is compared with the other only known species of the genus, <em>Eltxo cretaceus </em>Arillo &amp; Nel, 2000, based on a single male specimen also found in Spanish amber, but slightly younger (Peñacerrada I amber; upper Albian). The holotype of <em>E. cretaceus</em> is reviewed and its description corrected and expanded, providing the first micrographs of its anatomical features. The holotype of the new fossil species is the only female specimen known of the cecidomyiid tribe Amediini Jaschhof, 2021, a tribe recently described after changes of taxonomic attribution of the genus <em>Eltxo</em> during the last 20 years.</p> ENRIQUE PEÑALVER, ANTONIO ARILLO, ANDRÉ NEL Copyright (c) 2022 Magnolia press limited https://www.mapress.com/pe/article/view/palaeoentomology.5.5.7 Thu, 22 Sep 2022 00:00:00 +1200 <p><strong>Palleptoceridae fam. nov., an extinct leptoceroid family in mid-Cretaceous Burmese amber (Insecta, Trichoptera)</strong></p> https://www.mapress.com/pe/article/view/palaeoentomology.5.5.8 <p>The family Palleptoceridae <strong>fam. nov.</strong> is proposed as a new extinct family of the superfamily Leptoceroidea. It is characterized by the absence of ocelli, the presence of five-segmented maxillary palps in both sexes, antennae longer than the forewings, and the tibial spur in the form of 2/4/4. The extinct Palleptoceridae is closely related to the leptoceroid family Leptoceridae, but the formula for the adult tibial spur is reduced from 2/4/4 to 2/2/4 (Morse, 1981). The <em>Palleptocerus grimaldii</em> <strong>sp. nov.</strong> from the mid-Cretaceous Burmese amber is furthermore characterized by the sexual dimorphic wing venation. In the forewings, the apical forks I and V are present in the male and forks I, III, and V in the female; in the hind wings of both sexes, exclusively the apical fork V is present. The Leptoceroidea originated and evolved in Gondwana. <em>Palleptocerus grimaldii</em> <strong>sp. nov.</strong> is interpreted as a relict species of the Gondwanan Leptoceroidea in Burmese amber.</p> WILFRIED WICHARD, PATRICK MÜLLER Copyright (c) 2022 Magnolia press limited https://www.mapress.com/pe/article/view/palaeoentomology.5.5.8 Thu, 22 Sep 2022 00:00:00 +1200 <p><strong>Dolichopodidae (Diptera) from the Eocene amber deposits of Cambay and Kutch Basins, India</strong></p> https://www.mapress.com/pe/article/view/palaeoentomology.5.5.9 <p>The family Dolichopodidae (Diptera) from the Eocene amber of the Cambay and Kutch, India is reviewed. Based on a sample of 38 inclusions, the fauna preserved in amber reveals that the family was well-differentiated by early the Eocene. <em>Palaeomedeterus cambayensis</em> Bickel <strong>sp. nov.</strong> is described and provisionally assigned to the Peloropeodinae, and is congeneric with European Baltic amber species, suggesting the genus was widespread for a considerable time period in both Europe and India. Two small-sized new monotypic genera are also described, <em>Gujaratmyia rotunda</em> Bickel <strong>gen. et sp. nov.</strong> and <em>Rajpardia grimaldii </em>Bickel <strong>gen. et sp. nov.</strong> Also included are undescribed members of the dolichopodid subfamilies Diaphorinae and Medeterinae, and unplaced species. The Baltic amber species <em>Prohercostomus noxialis</em> (Meunier, 1907) is regarded as the new senior synonym of <em>Sympycnites</em> <em>primaevus</em> Grimaldi &amp; Cumming, 1999, described with a mistaken provenance of Cretaceous Lebanese amber.</p> DANIEL J.

The order is also represented in the fossil record from the Carboniferous (<em>ca</em>. 305–319 Ma) and the Cretaceous (<em>ca</em>. 99 Ma) periods. In the present contribution, <em>Hirsutisoma grimaldii</em> <strong>sp. nov.</strong>, a new extinct species of the suborder Primoricinulei Wunderlich, 2015, is described from a specimen preserved in Cretaceous Burmese amber. The specimen is a well-preserved adult male in which several taxonomically informative structures are visible, allowing the new species to be differentiated from <em>Hirsutisoma bruckschi</em> Wunderlich, 2017, the only other congener for which a male is known. This description raises the number of Cretaceous Ricinulei species to six. A comparative table documents morphological differences among the various species of this lineage. Hypotheses concerning the paleoecology and functional morphology of this species and, by extrapolation, other primoricinuleids, are presented. The evidence suggests that Primoricinulei were corticolous, scansorial predators.</p> RICARDO BOTERO-TRUJILLO, STEVEN R.

The differences with <em>D. burmitica</em> Blagoderov &amp; Grimaldi, the type-species of the genus, are discussed. The specimens allow the study of important details of the antenna, wing, and terminalia. The question of the connection of <em>Docidiadia</em> to the extant family Diadocidiidae is addressed. An antenna with the flagellum more slender towards the apex is also known in the extinct sciaroid family Archizelmiridae, but the wing venation of <em>Docidiadia</em> is much more conservative than the wing in archizelmirid genera.</p> DALTON de SOUZA AMORIM, BRIAN V.
