High Degree

The genus Cryphocricos Signoret, 1850 was recently determined in a molecular phylogeny to be distantly related to other taxa of the subfamily Cryphocricinae to the extent that it is now once again the sole member of the subfamily. This exclusively New World group of aquatic bugs lives in fast and usually turbulent current and respires by means of a plastron. Efforts to identify morphological features to distinguish among the species have largely fallen short, and some species have been established based on features that exhibit a high degree of intraspecific variation overlapping those of other species. Presented here is a review of the 13 described species with discussions of their features and photos of type specimens, and three new species from Venezuela and Colombia are described. Also presented is a diagnostic attribute unique to the enigmatic Cryphocricos barozzii Signoret, 1850.

Three New Species

Sinopoda spiders are a diverse group with limited dispersal ability. They are remarkably sympatric among related species, which often results in misidentification and incorrect matching of sexes. In order to understand the evolutionary relationships and revise the taxonomy problems in this genus, we offer the first molecular phylogeny of Sinopoda. Our results strongly support the monophyly of Sinopoda and its sister relationship with Spariolenus and reject the monophyly of the S. okinawana species group. We establish three new species groups based on both molecular and morphological data. Our phylogeny also illuminates some taxonomic issues and clarifies some species limits: (1) Supporting the newly revised matching of sexes in S. longiducta and S. yaanensis by Zhong et al. (2019). (2) The original description of S. campanacea was based on mismatched sexes. S. changde is proposed as a junior synonymy of S. campanacea, while the original female ‘S. campanacea’ is here described as a new species: S. papilionaceous Liu sp. nov. (3) The type series of S. serpentembolus contains mismatched sexes. The female is considered as S. campanacea, while we here report the correctly matched females of S. serpentembolus. (4) We describe one additional new species: S. wuyiensis Liu sp. nov. Our first molecular phylogeny of Sinopoda provides a tool for comparative analyses and a solid base for the future biodiversity and taxonomic work on the genus.

Three new species of Russulaceae, Lactifluus umbonatus and Lactifluus indicus belonging to Lf. subg. Gerardii and Lactarius keralensis belonging to L. subg. Piperites, are described from Kerala State, India. Comprehensive descriptions, photographs, line drawings and comparisons with phenetically similar and phylogenetically related species are given. Nuclear ribosomal internal transcribed spacer regions (ITS) of the three species were sequenced and analyzed. In addition, nuclear ribosomal large subunit (nLSU) gene of Lactifluus indicus was sequenced and the sequence was used in BLASTn search to find similar sequences. Maximum likelihood (ML) analysis based on the ITS sequences confirmed both the novelty of these species and their placement within their respective genera. The discovery of Lactifluus umbonatus and Lf. indicus represent the first report of novel species belonging to Lf. subg. Gerardii from India. Lactifluus indicus represents the second record of a pleurotoid Lactifluus species from India.

Three new species of Calocybella, C. lohitha, C. babruka and C. swetha are described from Kerala State, India based on morphology and molecular phylogeny. Comprehensive descriptions of these species are provided along with photo-illustrations and comparisons with phenetically similar and phylogenetically related species. Nuclear ribosomal internal transcribed spacer (ITS) region of the three species were sequenced and analyzed. In addition, nuclear ribosomal large subunit (nrLSU) region of Calocybella swetha was sequenced and used in BLASTn search to find similar sequences. ITS-based phylogenetic analysis using Maximum likelihood (ML) method supported both the novelty of these species and their placement within the genus. The discovery of these three species forms the first record of Calocybella outside Europe.

A molecular phylogeny of the western Palearctic weevil genusOnyxacallesStüben, 1999 is presented, combining two mitochondrial genes (COI and 16S) in a Bayesian analysis. Based on molecular data,Onyxacalles pyrenaeusBoheman, 1844 is transferred into the genusKyklioacallesStüben 1999 (K. faustigroup) and—in an integrative taxonomy framework—the interaction between morphology and molecular analysis is illustrated. The species ofOnyxacalless. str. are assigned to three new species groups,O. henoni,O. luigionii, andO. portusvenerisgroups. The distribution of the related species in the Mediterranean area is illustrated with values of COI and 16S p-distances. Three new species are described and distinguished from their related species:Onyxacalles nuraghiStüben sp.n. from Italy (Sardinia),Onyxacalles torreStüben and Astrin sp. n. from France (Corsica) andOnyxacalles vilaeStüben sp. n. from Croatia (Velebit Mts.). A catalogue of all 20 species ofOnyxacallesis given, and a key is finally presented combined with image stacking of the habitus and aedeagus for all species.

Three New Species

Abstract:The new genus Atla forms a well-supported clade in a molecular phylogeny based on the ITS1-5.8S-ITS2 and LSU regions of the nuclear ribosomal DNA. The genus has a crustose thallus, a hamathecium at maturity without hyphal elements except for pseudoparaphyses remaining at the ostiolum, and large, muriform spores. Atla wheldonii was previously referred to Polyblastia. Three new species, A. alpina (the type of the new genus), A. palicei and A. praetermissa, are included in the genus and described here as new to science. They were found on calcareous rocks and soil in Northern Scandinavia; A. alpina also occurs in Central Europe, and A. wheldonii likewise in Central Europe, the Pyrenées and in the British Isles. An identification key to the species and a revision of the genus are also provided.
