A New Species

Zangerlia neimongolensis sp.nov. is described on the basis of material from the Upper Cretaceous redbeds at Bayan Mandahu in Inner Mongolia. Zangerlia neimongolensis is similar to Zangerlia testudinimorpha in the proportions of the carapace and plastron and presence of a knob at the posterior end of the neural series, but differs from it in the arrangement of scutes covering the bridge. The placement of Zangerlia in the Nanhsiungchelyidae is supported by derived features of the bridge peripherals and plastral scutes shared by Z. neimongolensis, Basilemys, and Nanhsiungchelys. These are the presence of ventrally expanded sixth inframarginal scutes, humeral scutes that are narrow at the midline and expanded laterally, pectoral scutes that are wide at the midline and narrow laterally, and large rectangular abdominal scutes. The skull of Zangerlia is more primitive than that of Nanhsiungchelys, the only other member of the family for which a skull is known. It shows extensive emargination of the temporal and cheek regions and the absence of a large, tubular external narial opening. A cladistic analysis of the Trionychoidea using Zangerlia as the representative of the Nanhsiungchelyidae suggests a sister-group relationship between the Nanhsiungchelyidae and Adocidae.

A cladistic analysis of the 13 known species of Sepedonea Steyskal, 1973, is presented and a new species, Sepedonea giovana sp. n., is described. The monophyly of the genus is confirmed, as is the genus’ sister-group relationship to Sepedomerus Steyskal, 1973. The cladistic analysis was done using NONA and a matrix of 27 adult morphological characters, including structures of the male and female terminalia. The relationships in parenthetic notation are: (S. guatemalana (S. veredae (S. lindneri (S. isthmi (S. lagoa ((S. barbosai+ S. canabravana) ((S. neffi (S. giovana+S. guianica))(S. telson (S. incipiens+S. trichotypa))))))))).

Corotoca is a strictly Neotropical genus of termitophilous beetles associated with termites of genus Constrictotermes. A cladistic analysis based on 13 terminal taxa and 60 characters (57 morphological and three behavioral) was conducted. The exhaustive search with equally weighted characters resulted in two most parsimonious trees with 95 steps. Spirachtha is proposed to be the sister group of the monophyletic “subgroup Corotocae” (Corotoca + Cavifonexus gen. nov.), based on eleven synapomorhphies (ten exclusive and one homoplastic). The monophyly of Corotoca is supported here, including six species associated with Constrictotermes cyphergaster: (Corotoca hitchensi sp. nov + (C. melantho + C. pseudomelantho sp. nov.) + ((C. fontesi + (C. phylo + C. araujoi)). A new genus, Cavifronexus gen. nov., is proposed to two species associated with Constrictotermes cavifrons (Holmgren, 1910): Cavifronexus guyanae comb. nov., from Guyana and Brazil, previously described as Corotoca; and a new species, Cavifronexus papaveroi sp. nov., from Brazil. This work also includes descriptions, redescriptions, and illustrations for all species and genera. Keys for genera and species identification in “subgroup Corotocae” are also provided.

A New Species

Psychodidae Newman, 1834 is a large family of small, hairy nematoceran dipterans, comprising more than 2,600 described extant species. It is currently subdivided into seven subfamilies: Bruchomyiinae Alexander, 1920, Horaiellinae Enderlein, 1936, Phlebotominae Rondani, 1840, Psychodinae Newman, 1834, Sycoracinae Jung, 1954, Trichomyiinae Tonnoir, 1922, and the fossil subfamily Protopsychodinae Stebner et al., 2015. Some authors consider the group to consist of two families, i.e., Psychodidae and Phlebotomidae (Williams, 1993; Azar et al., 1999). This fact is founded only on the hematophagous and medically important aspects of the phlebotomines, nevertheless this arrangement is unfounded, because the phylogenetic relationships between the psychodid subfamilies remain unresolved, even if there is a possible sister-group relationship between the Phlebotominae and Psychodinae (Curler & Moulton, 2012). We consider recognizing phlebotomines as a separate family would necessitate also giving separate familial status to all the currently recognized subfamilies, which is not adopted here.

Silicified material from the Early Caradoc part of the Las Aguaditas Formation in San Juan Province, Argentina, includes a nearly complete growth series for a new species of the tropidocoryphid Stenoblepharum Owens, 1973. Cladistic analysis of Stenoblepharum species indicates that S. astinii new species is most closely allied to the Early Caradoc S. strasburgense (Cooper, 1953) from Virginia. Chinese species of Stenoblepharum are sister group to a Baltic/Laurentian clade. A single adult-like protaspid stage occurs in the life cycle of S. astinii, closely resembling the protaspis of Decoroproetus. It is preceded by a non-adult-like first protaspid instar that appears to be characteristic of Proetoidea in general but contrasts markedly with the early larval stages of other taxa in Proetida.

Leptopeltus trogloxenus López-Prada & Chani-Posse, a new species of the subtribe Philonthina (tribe Staphylinini) from the Andes of Colombia, is described and illustrated. A dataset of 49 morphological characters scored for 10 taxa, including all currently known species of Leptopeltus Bernhauer and its putative sister group, Leptopeltoides Chani-Posse & Asenjo, was prepared and analysed by maximum parsimony. Our analysis unambiguously placed L. trogloxenus within Leptopeltus in a sister-group relationship with a clade of four species. A revised key to species and an updated phylogeny of Leptopeltus are also provided.

In this paper, the monophyly of the genus Thoreyella Spinola was tested, and a hypothesis of relationships among its species is proposed. Four known species of Thoreyella and two new species, as well as species of three other genera of Procleticini (Neoderoploa Pennington, Lobepomis Berg, and Procleticus Berg), were treated as the ingroup. The new species of Thoreyella will be published elsewhere. Two species of Dendrocoris were used for outgroup comparison. A cladistic analysis of 38 morphological characters supported a hypothesis of common ancestry for Thoreyella and the three genera of Procleticini included in the ingroup. The results also showed Thoreyella as a monophyletic taxon, and its sister group relationship with the monophyletic group including Neoderoploa, Lobepomis, and Procleticus. The geographical distribution of these taxa is discussed.

High Degree

A cladistic analysis of the species of Calloserica Brenske, 1894, was executed using 49 morphological characters of adults. The generated phylogenetic tree supports the monophyly of the genus and the sister-group relationship between Pachyserica and (Gastroserica, Neoserica). Allopatric speciation is discussed as an important mechanism for explaining present tree topology and distribution patterns. Emergence of adults (and mating) during the monsoon season is considered to be a major factor for stimulating the diversification of this group, resulting in its highly restricted distribution and a high degree of endemism. Two new species are described from Nepal: Calloserica capillata, sp. nov. and C. manangensis, sp. nov.

A New Species

A third species of the southern temperate tabanomorph genus Austroleptis Hardy, 1920 (Diptera: Austroleptidae)—A. camposgerais sp. nov.—from the Brazilian Atlantic Forest is described and illustrated. A key for the species of the genus in Brazil is provided. Shared derived features indicate a sister group relationship between the new species and A. longirostris Fachin et al., 2018. Whatever the relationships among the species of this clade, however, there is a process of endemism within endemism in the Atlantic Forest: species at higher altitudes undergo vicariance process that do not affect lowland species distributed around the mountain chains. The low number of specimens known from highland species and the very restricted geographic distribution of each species strongly indicate the urgency to protect the natural environments at higher altitudes in Brazil.
