A New Species

An unusual new omaliine species, Anthobium alekseevisp. nov., is described and illustrated from Eocene Baltic amber, tentatively placed in the megadiverse genus Anthobium Leach, 1819. A new monotypic species-group is established. The new species can easily be distinguished from other species of the genus by the larger body, shape of the subrectangular pronotum, and the presence of a median carina on the prosternum and large, subtriangular tooth on the inner side of each mesotibia, likely exhibiting a peculiar sexual dimorphism in the male. Based on the study of the specimen with support of microtomographic images, a brief comparative analysis of a new species with described extant species of Anthobium is provided.

Lonchodryinus groehni sp. nov. (Hymenoptera: Chrysidoidea: Dryinidae) is described from Baltic amber. The new species is close to L. balticus Olmi & Guglielmino, 2012, but it can be distinguished for the different OPL/POL ratio and 2r-rs&Rs vein of the fore wing. A key to the fossil species of Lonchodryinus and a comparison with the extant species L. ruficornis (Dalman, 1818) are presented.

ABSTRACT Phloeocharinae is a small and likely non-monophyletic subfamily of rove beetles. The enigmatic genus Charhyphus Sharp, 1887 has long been placed in Phloeocharinae, whereas recent studies have found it to be phylogenetically very distant from the core members of this subfamily, suggesting the possibility that it actually deserves its own separate subfamily status. So far, the sole definitive fossil record for Charhyphus is known based on a single male from Eocene Baltic amber as represented by †Charhyphus balticus Shavrin, 2020. Here, we describe and illustrate another new Charhyphus species, †Charhyphus serratus sp. nov. Yamamoto & Shavrin, from Baltic amber based on a well-preserved female fossil. Considering the general proportions of the body and the head, this new species is most similar to †C. balticus. The new species differs from all known species by the development of strong serration of the lateral edges of the pronotum and features of the shape of the apical margin of the mesoventrite. By using X-ray micro-computed tomography, we succeeded in visualising not only the general habitus but also each individual body part, recovering a previously undocumented sclerite on the female internal genital segments in the genus. Morphological features of extinct and extant species of Charhyphus are briefly discussed. Figures of all extant Charhyphus species and a key for the genus are also provided. Our study is important for considering possible higher palaeodiversity, more common occurrence, and palaeobiogeography of Charhyphus.

A New Species

A new species of the romaleid grasshopper genus Zoniopoda Stål (Romaleidae: Romaleini) is described and illustrated from the Sierras Chicas of Córdoba Province, central Argentina. A cladistic analysis based on morphological characters indicates that the genus Zoniopoda constitutes a monophyletic group and that Zoniopoda serrana n. sp. must be assigned to Iheringi species group based on synapomorphies of the pronotum and body color. The new species is similar to Z. similis Bruner from Paraguay, Bolivia and Brazil, from which it can be distinguished by the color pattern of the body, shape of the pronotal dorso-median carina and characters of the male terminalia and epiphallus. This paper has been formatted with embedded links to images of the type specimen, maps based on georeferenced specimen data for the genus and an updated key to the species of Zoniopoda available on the Orthoptera Species File (OSF) online (http://orthoptera.speciesfile.org).

The tribe Diglottini Eichelbaum, 1909 comprises two halophilous rove beetle genera Diglotta Champion, 1899, and Paradiglotta Ashe & Ahn, 2004. The tribe contains eight known species distributed in the Nearctic and West-Palaearctic regions, and also Fiji Islands and New Zealand. This tribe is recorded for the first time from South America with the description of a new species, Diglotta brasiliensis n. sp. from southern Brazil (Paraná). Characters of the mouthparts, aedeagus and spermatheca of the new species are illustrated and compared with other Diglotta species. Sexual dimorphism is reported for the first time in the genus.

A New Species

A small number of treefrog species (Litoria) from Melanesia are unusual amongst Anura in having distinctive fleshy rostral spikes. Here, we first present an extended description for Litoria pronimia Menzies, a small species that is widespread along the southern edge of the Central Cordillera of New Guinea, and in which males have a long and erectile rostral spike. Second, we describe Litoria pinocchio sp. nov. a new, morphologically similar, yet geographically disjunct species from the Foja Mountains in northern Papua Province, Indonesia. The new species differs from Litoria pronimia in aspects of body shape, proportions and colouration. A review of variation in the size, structure and degree of sexual dimorphism of the rostral spike across different species of Litoria suggests varying function including mate selection and camouflage.

A New Species

Abstract. A new specimen of Lacinius Thorell, 1876; (Opiliones: Phalangiidae) from Eocene Baltic amber is described. We interpret it as conspecific with a slightly younger record from the German Bitterfeld amber, originally referred to as the extant species L. erinaceus Staręga, 1966. Our new specimen reveals pedipalpal apophyses on both the patella and the tibia, features which we can now confirm in the Bitterfeld fossil too. This unique character combination for the genus justifies a new, extinct species: Lacinius bizleyi sp. nov. The Baltic amber inclusion dates to ca. 44–49 Ma, and is thus the oldest putative example of Lacinius in the fossil record. It is a further example of an arachnid species shared between Baltic and Bitterfeld amber.

A New Species

In this paper we describe and illustrate Zercon hamaricus sp. nov. based on all postembryonic stages obtained from soil samples and laboratory cultures. The new species belongs to a species group in which dorsal setae J1–J4 in females are short and similar in length, and J5 are considerably longer. In most species of this group opisthonotal setae J5 and Z4 are clearly displaced anteriorly. Zercon hamaricus sp. nov. is most similar to Z. forsslundi Sellnick, 1958 and to a less extent to Z. polonicus Błaszak, 1970. The females of Z. forsslundi, Z. polonicus and Z. hamaricus sp. nov. can be distinguished based on the range of J5, the length and character of the Z and S-series setae, the distance between setae Z5 and the location of gdZ3. We also include comparative information on other related species of Zercon. The new species is one of the six known species that have clearly visible sexual dimorphism in opisthonotal chaetotaxy.

A new species of comb-clawed beetles of the genus Asiomira Dubrovina, 1973 (A. dubrovinae sp. n.) is described from the Eocene Baltic amber. This newly descovered fossil species displays typical generic characters and is the most similar to the extant Asiomira ophtalmica (Seidlitz, 1896). Both species share a similar shape of the pronotum and the flattened posterior angles of the pronotal disc. Asiomira dubrovinae sp. n. can be distinguished from A. ophtalmica by the smaller body size (4.8 mm in contrast to 6–8.12 mm), more serrate antennomeres, and finer and sparser pronotal punctation. Extant species of the genus are distributed in the arid landscapes of Central Asia with the highest diversity occurring in Tajikistan. Therefore the discovery of a new fossil species from Eocene Baltic amber suggests that Asiomira could have a wider range, and the modern distribution of this group is the result of a later secondary expansion of the ancestral representatives that survived in mid-mountain areas with arboreal and shrub vegetation. Relevant corrections to the distribution of extant species, Asiomira ophtalmica (Seidlitz, 1896) and Asiomira firjusana (Dubrovina, 1973), are given.

Catinia aiso sp. n. was found in association with the mud shrimp, Axianassa australis Rodrigues & Shimizu, 1992 collected in the intertidal zone of Araçá Beach, state of São Paulo, Brazil (23°48’50’’S, 45°23’48’’W). The new species shares with Catinia plana Bocquet & Stock, 1957 the structure of the oral appendages, the setal formula of the swimming legs, the robust pedunculate sucker on the antenna, and the absence of the maxilliped in adult females. However, the two species can be separated by the rostrum shape, the presence or absence of an inner coxal seta on leg 4, and the structure of leg 5 in both sexes. Catinia aiso also differs from C. plana in the depressed ovoid body shape, the ornamentation of the maxilla in the female and in the modified claw of the maxilliped of the male. The sexual dimorphism expressed in the armature of the antennule and the endopodal segments of the swimming legs in C. plana, is absent in C. aiso. This is the first record of Catinia since the genus was established on the basis of material from the Baie de Morgat, France, in 1957.
