Abstract—We present a taxonomic revision of Dactylaena and Haptocarpum as part of a series of generic revisions and delimitation of Neotropical Cleomaceae. Two new species are described, Dactylaena boliviensis and D. zmarztyae, one new combination is made, D. monandra, four lectotypes are designated in Dactylaena, and a key to all species is presented. This is the first comprehensive revision of the now seven recognized species of Dactylaena and provides needed clarification of species boundaries, distributions, and diversity. Haptocarpum is maintained as a monotypic genus.

Two New Species

The fern family Didymochlaenaceae contains the genus Didymochlaena only. This genus is generally believed to comprise one species only, while morphological polymorphism in this species has long been observed. Here we conducted a taxonomic revision of Didymochlaena from Madagascar and recognized six species including two new species, three new statuses, and one new combination. A key to the Malagasy species and detailed descriptions of all species recognized are provided.

River Drainages

The taxonomic revision of the genus Lamontichthys Miranda-Ribeiro, based on the examination of 164 specimens of different river drainages throughout the Amazon basin, revealed the presence of six species of which two are new. Lamontichthys filamentosus occurs in the upper and middle portions of the rio Amazonas basin; L. llanero in the río Orinoco basin; L. maracaibero in the lago Maracaibo basin; and L. stibaros in the upper río Amazonas basin. Lamontichthys avacanoeiro, new species, occurs in the upper rio Tocantins basin; and L. parakana, new species, in the lower rio Tocantins basin. The new species represent a considerable extension in the so far known distribution of the genus. A parsimony analysis, including 87 osteological and external morphological characters from Lamontichthys and related taxa (total of 16), resulted in three most parsimonious trees with 194 steps (CI = 0.73 and RI = 0.78). The hypothesis of monophyly of Lamontichthys is corroborated and supported by six derived characters. Within Lamontichthys two monophyletic assemblages are recognized, one includes L. avacanoeiro and L. stibaros, the other includes L. maracaibero and the clade formed by L. filamentosus and L. llanero. The relationships of Lamontichthys parakana, a species that was not included in the phylogenetic analysis is discussed. The monophyly and relationships of the monotypic genus Pterosturisoma microps are also discussed.

The Afrotropical scarab beetle genus Cerhomalus Quedenfeldt, 1884 (Coleoptera: Scarabaeidae) is revised. Two new species are described: C. quedenfeldti sp. nov. and C. petrovitzi sp. nov. A new combination, Cerhomalus absconditus (Petrovitz, 1971) comb. nov., is established. The genus occurs in Central and West Africa with the majority of records from the Congo Basin. Keys, descriptions, illustrations of habitus and male genitalia, and distributional record map are given

Abstract Bed-by-bed sampling of twelve Barremian sections in southeastern France from pelagic basin (Vocontian Basin) to neritic platforms (Arc of Castellane, Arc of Nice and Provencal Domain) has enabled the collection of isochronous samples of the ammonite genus Gassendiceras. Three poorly known species of the Toxancyloceras vandenheckei Zone (Upper Barremian) are revised: G. alpinum, G. multicostatum and G. hoheneggeri; two new species are described (G. rebouleti nov. sp. and G. bosellii nov. sp.). The intraspecific variability of particular species was recognised. This variability is between slender peramorphic and robust paedomorphic extreme morphologies, with the presence of all intermediates.

Respective Species

The South American genus Panca Evans, 1955 and its respective species are revised. Previous to this study, the genus included solely its type species, Lerodea subpunctuli Hayward, 1934, until Panca moseri Dolibaina, Carneiro & O. Mielke, 2017 was described recently. However, as a result of a broader morphological study including closely related genera, we here propose that Panca assembles 12 species, most of which inhabit open environments such as the Cerrado biome and the natural grasslands of the Atlantic Forest biome. Eight species formerly included among other genera of Moncina are here combined with Panca: Panca satyr (Evans, 1955) comb. nov., Panca tobiasi (Mielke, 1992) comb. nov., Panca trogon (Evans, 1955) comb. nov., Panca steinhauseri (Dolibaina & A. Warren, 2015) comb. nov., Panca acroleuca (Plötz, 1884) comb. nov., and Panca mirnae (O. Mielke, Dolibaina, Carneiro & A. Warren, 2015) comb. nov. (all formerly in Artines Godman, 1901), Panca paulo (Bell, 1932) comb. nov. (formerly in Eutocus Godman, 1901), and Panca mictra (Evans, 1955) comb. nov. (formerly in Vidius Evans, 1955). Additionally, two new species are described from Brazil: Panca puri Medeiros, O. Mielke & Casagrande sp. nov. (from Pará, Pernambuco, Minas Gerais, Rio de Janeiro and Paraná) and Panca xavante Medeiros, O. Mielke & Dolibaina sp. nov. (from Mato Grosso, Goiás, Distrito Federal and Minas Gerais). A neotype for Apaustus acroleuca Plötz, 1884 is designated. Illustrations of the male and female genitalia and distribution maps are presented for all the species of Panca and an identification key is provided for both sexes.

This study presents the first records of the subfamily Lestremiinae and the genus Insulestremia Jaschhof in Brazil. Insulestremia, a previously monotypic genus described from the Galapagos Islands, has three species in Brazil: I. sinclairi Jaschhof, I. amorimi sp. nov. and I. amenti sp. nov. The new species are described, the generic concept is reviewed, and a key to the species of Insulestremia is provided.

Subjective Synonym

The genus Surenus Distant, 1901 (Hemiptera: Heteroptera: Pentatomoidea: Pentatomidae: Pentatominae: Halyini) is revisited and found to be a junior subjective synonym of the genus Agathocles Stål, 1876 (currently Pentatominae: Rolstoniellini). The genus Agathocles and its type species, Agathocles limbatus Stål, 1876, are redescribed. Lectotype of Surenus normalis Distant, 1901 (= Agathocles normalis (Distant, 1901) comb. nov.) is designated and the unknown male of the species is described. Agathocles yunnanensis Zhang & Lin, 1984, syn. nov., is considered junior subjective synonym of A. limbatus. Two new species are described: Agathocles flavipes sp. nov. from India (Andhra Pradesh, Karnataka, Maharashtra, and Tamil Nadu) and A. joceliae sp. nov. from Malaysia (Kelantan, Perak). The new species differ from their congeners mainly by the morphology of mandibular plates, length of antennomeres I, IIa and IIb, body length, and structure of male genitalia. Agathocles dubius Distant, 1921 is transferred to the genus Caystrus Stål, 1861 (Pentatominae: Caystrini) based on examination of its holotype with the resulting new combination: Caystrus dubius (Distant, 1921), comb. nov. One new combination is proposed, Paramecocoris ruficornis (Fieber, 1851), comb. nov. (from preoccupied Paramecus Fieber, 1851), and its type locality is clarified as Tenasserim (south Myanmar). Gender agreement and authorship of the name Riazocoris niger Ahmad & Afzal, 1977 in Ahmad et al. (1977: 161) are corrected and status of its name bearing type is clarified as lectotype. The following new distribution records are given: A. limbatus from Cambodia, China (Guangxi, Tibet), Laos and Thailand, A. normalis, Caystrus obscurus (Distant, 1901a) and Critheus lineatifrons Stål, 1869 from Laos, Amasenus corticalis Stål, 1863 from Cambodia, Indonesia (E Kalimantan), Laos, Myanmar and Thailand, and Rolstoniellus boutanicus (Dallas, 1849) from Vietnam. Based on characters of external morphology and genitalia, the genus Agathocles is compared with representatives of the genera Halys Fabricius, 1803 (Halyini), Caystrus (Caystrini), Laprius Stål, 1861 (Myrocheini), and Exithemus Distant, 1902 (currently in Rolstoniellini). As a result, the genus Agathocles is here transferred to the tribe Caystrini. The genus Kyrtalus Van Duzee, 1929 is tentatively placed in Myrocheini based on the presence of sulcate mesosternum and femora provided with teeth.
