The earliest mammaliaforms are difficult to assess because the fossil record is poor and because their distinctive morphologies cannot be directly compared with more recent mammaliaforms. This is especially true for the haramiyid genusTheroteinus, only known in the Saint-Nicolas-de-Port locality (Rhaetian, France). This study presents a new definition of the type-speciesTheroteinus nikolai. A new speciesTheroteinus rosieriensis, sp. nov., is named and distinguished by the lingual shift of distal cusps, a larger size, and a stockier occlusal outline. Comparisons withEleutherodon,MegaconusandMillsodonsuggest thatTheroteinushas potential close relatives among the Jurassic haramiyids.

A cladistic analysis of the genus Melanophora Meigen, 1803 (type-species: Musca grossificationis Linnaeus, 1758 [= Musca roralis Linnaeus, 1758]) is presented and the generic delimitation is critically redefined. The nominal genus-group taxon Bequaertiana Curran, 1929 (type-species: Bequaertiana argyriventris Curran, 1929) is synonymised with Melanophora Meigen syn. nov. The following new combinations are proposed: Melanophora argyriventris (Curran, 1929) comb. nov. and Melanophora basilewskyi (Peris, 1957) comb. nov. Melanophora chia sp. nov. from SW Sardinia is described, illustrated and compared with the other known species of the genus. The male of Melanophora asetosa Kugler, 1978 is described for the first time. Melanophora basilewskyi (Peris, 1957) is recorded from Kenya for the first time.

The genus Sphaeronemoura is reported from the Palaearctic Region for the first time, accompanied with a new species added from northern China, Sphaeronemoura songshana sp. nov. Sphaeronemoura hamistyla (Wu, 1962) is redescribed and reillustrated for comparison based on the holotype and fresh material. Their relationships with close relatives are discussed. Unassociated females for one species are also described for further understanding of the genus under informal designation. Clarification or further definition of the generic characters and remarks on questions of Shimizu & Sivec (2001) are presented.

Ptychopteridae is an ancient and rather diverse nematoceran family with three extant and 12 fossil genera subdivided into 80 extinct species belonging to five subfamilies (Eskov & Lukashevich, 2015; Lukashevich, 2019, 2020; Liu & Huang, 2020). Several undescribed ptychopterid larvae from the Upper Triassic of Germany represent the oldest record of the family (Barth et al., 2011). Crenoptychoptera Kalugina, 1985, an extinct genus belonging to the subfamily Eoptychopterinae Handlirsch, 1906, includes seven described species. All these species were recorded from the Lower Jurassic to the Lower Cretaceous of Eurasia: C. dobbertinensis Ansorge, 1998 from the Lower Jurassic of the Former Clay in Germany (Lukashevich et al., 1998), C. conspecta Lukashevich, 1995 from the Lower Jurassic of Ust-Baley in Russia (Lukashevich, 1995), the type species C. antica Kalugina, 1985 and C. defossa Kalugina, 1985 from the Middle Jurassic of the Kubekovo in Russia (Kalugina & Kovalev, 1985), C. bavarica Krzemiński & Ansorge, 1995 from the Upper Jurassic of Wegscheid in Germany (Krzemiński & Ansorge, 1995), C. liturata Lukashevich, 2011 from Upper Jurassic of Shar Teg in Mongolia, and C. gronskayae Kalugina, 1989 from the Upper Jurassic to Lower Cretaceous of Kempendyay in Russia (Kalugina, 1989; Lukashevich, 2011). Three species discovered from the Daohugou beds of China have been assigned to Crenoptychoptera (Hao et al., 2009), but a following study suggested that they should be placed in Axymyiidae (Zhang, 2010).

Abstract. The taxonomic identity of the dinoflagellate cyst genus Polygonifera Habib, 1972 is confirmed, through the recognition of additional morphological characters during the study of specimens from Early-Middle Cretaceous sediments of India. A revised definition of this genus is presented. Leberidocysta Stover & Evitt, 1978 is considered a subjective junior synonym of Polygonifera and its type species Leberidocysta (ex: Hexagonifera) chlamydata (Cookson & Eisenack) is transferred to Polygonifera. The other species placed in Leberidocysta are provisionally reattributed to other genera, becoming Craspedodinium (ex: Hexagonifera) defloccata (Davey), Craspedodinium (ex: Palaeostomocystis) pergamentacea (Burger), Hexagonifera laticaudata Vozzhennikova and Hexagonifera scabrata Jain & Taugourdeau-Lantz. A new species, Polygonifera eisenackii, is described. Morphological differences between the camocavate genera Polygonifera and Dingodinium are clarified.

Parapachymorpha is one of eight genera within the tribe Medaurini of subfamily Clitumninae (Phasmatidae). It was established by Brunner von Wattenwyl (1893), with the type species Parapachymorpha nigra by subsequent designation of Kirby (1904), from Myanmar. Species of this genus are widely distributed in oriental tropics (Laos, China, Thailand, Myanmar, Vietnam and Cambodia), with only 11 known species in the world (Brock et al. 2018, Ho 2017). Species of the genus Parapachymorpha can be recognized by following characters (Brunner von Wattenwyl 1893;1907, Henmemann & Conle 2008, Ho 2017): 1) body robust in female and slender in male with long leg in relation to the length; 2) body surface of female granulose or spinose; 3) mesonotum of female more and less expanded posteriorly; 4) abdominal tergites lacking expanded prostero–lateral angles in both sexes; 5) laminal supraanalis undeveloped in female; 6) semi–tergite of male irregularly rectangular, with an additional finger­–like ventro–apical appendix on the lower margin and reduced or absent; 7) egg capsule oval to oblong and covered with a raised net–like structure in lateral view; 8) micropylar plate oval; 9) operculum concave or convex. In the present study, we describe additional species, Parapachymorpha minuta sp. nov. from Laos, with photographs of both sexes of adults and egg.

Abstract A new species of Hippopotamidae, Hexaprotodon dulu nov. sp., was discovered in the Middle Awash valley, Afar, Ethiopia. It was found in the Sagantole Formation, within volcaniclastic beds aged between 5.2 Ma and 4.9 Ma (40Ar/39Ar). It is therefore the oldest hippo species described as yet from Ethiopia. This hexaprotodont hippo exhibits a general morphology that is primitive, close in that respect to other Mio-Pliocene forms. However, its cranium and dentition display a distinctive association of measurements and features. This new species increases the hippo fossil record in East Africa. It also reinforces the hypothesis of hippo endemism in each African basin as early as the basal Pliocene.
