Abiinae is the second-largest subfamily in Cimbicidae, a small family of true sawflies (Tenthredinoidea). The subfamily is adequately defined, but the generic classification has been unstable. Currently, only two genera are regarded as valid: Abia Leach, 1817 and Allabia Semenov & Gussakovskij, 1937. We evaluate the generic classification of Abiinae in a phylogenetic context. A total of 32 species (out of 57 described for the subfamily), including the type species of Allabia, Allabia infernalis (Semenov, 1896), are scored for 150 adult morphological characters. Results show some resolution, but only few clades can be circumscribed by consistent character combinations. Most of the characters that have previously been used to define genera are not congruent; consequently, most suggested genus definitions appear to be random character state combinations and few natural groups can be identified. For these reasons, we treat Allabia syn. nov. as a junior synonym of Abia and make the following additional taxonomic changes: Abia infernalis Semenov, 1896 comb. rev. and Abia malaisei (Semenov & Gussakovskij, 1937) syn. nov. For the purpose of long-term stability of the classification of Abiinae, we recommend recognizing only one genus, Abia, within the subfamily.

Three New Species

Resuming published and own data, a revision of classification of Chaetognatha is presented. The family Sagittidae Claus & Grobben, 1905 is given a rank of subclass, Sagittiones, characterised, in particular, by the presence of two pairs of sac-like gelatinous structures or two pairs of fins. Besides the order Aphragmophora Tokioka, 1965, it contains the new order Biphragmosagittiformes ord. nov., which is a unique group of Chaetognatha with an unusual combination of morphological characters: the transverse muscles present in both the trunk and the tail sections of the body; the seminal vesicles simple, without internal complex compartments; the presence of two pairs of lateral fins. The only family assigned to the new order, Biphragmosagittidae fam. nov., contains two genera. Diagnoses of the two new genera, Biphragmosagitta gen. nov. (type species B. tarasovi sp. nov. and B. angusticephala sp. nov.) and Biphragmofastigata gen. nov. (type species B. fastigata sp. nov.), detailed descriptions and pictures of the three new species are presented.

Taxonomic Changes

During a study of Discocyrtus Holmberg, 1878 and related genera, several species of alleged Pachylinae, mostly Discocyrtus, from southern Brazil were suspected of belonging in Roeweriinae. Herein, a maximum parsimony phylogenetic analysis of morphological characters was performed to test this hypothesis. Accordingly, the following taxonomic changes are herein proposed: the genus Bunopachylus Roewer, 1943 (currently in Pachylinae) is herein revalidated from synonymy with Discocyrtus, transferred to the Roeweriinae and now includes three species: B. armatissimus comb. nov. (for Discocyrtus armatissimus Roewer, 1913), B. orientalis comb. nov. (for Pachyloides orientalis Roewer, 1913) and B. occultus sp. nov. (which had been misidentified in the literature). A total of five new synonymies are proposed here: Discocyrtus milloti Roewer, 1943 = Discocyrtus coronatus Mello-Leitão, 1935 = Paradiscocyrtus trochanteralis Roewer, 1929 = Discocyrtus calcarifer Roewer, 1917 = Pachyloides orientalis Roewer, 1913, and Bunopachylus magnicalcar Roewer, 1943 (the type-species of Bunopachylus) = Discocyrtus armatissimus Roewer, 1913.

Taxonomic Changes

Extant genera and subgenera of the Trogidae (Coleoptera: Scarabaeoidea) are reviewed. Contemporary classifications of this family have been based exclusively on morphological characters. The first molecular phylogeny for the family recently provided strong support for the relationships between morphologically defined genera and subgenera. On the basis of morphological, molecular and biogeographical evidence, certain taxonomic changes to the genus-level classification of the family are now proposed. The family is confirmed as consisting of two subfamilies, Omorginae Nikolajev and Troginae MacLeay, the former with two genera,OmorgusErichson andPolynoncusBurmeister, and the latter with two genera,TroxFabricius andPhoberusMacLeaystat. rev.Phoberusis restored to generic rank to include all Afrotropical (including Madagascan endemic) species;Afromorgusis confirmed at subgeneric rank within the genusOmorgus; and the monotypic Madagascan genusMadagatroxsyn. n.is synonymised withPhoberus.The current synonymies ofPseudotroxRobinson (withTrox),ChesasBurmeister,LagopelusBurmeister andMegalotroxPreudhomme de Borre (all withOmorgus) are all accepted to avoid creating speculative synonyms before definitive phylogenetic evidence is available. New combinations resulting from restoringPhoberusto a monophyletic genus are listed in Appendix A.

The checklist of the New World Melolonthinae published in 2003 by Evans is updated to 30 June 2005. Corrections and omissions to the previous checklist are also noted and necessary taxonomic changes are made. Melolontha elongata Fabricius, 1792 is designated as the type species of Philochloenia Dejean, 1833, syn. nov. thereby placing this genus as a junior synonym of Dichelonyx Harris, 1827. Phyllophaga guatemalica (Moser, 1918), syn. nov. and Phyllophaga longiclava (Moser, 1918), syn. nov. are placed in synonymy with Phyllophaga ravida (Blanchard, 1851). The Australian genus Deuterocaulobius Dalla Torre, 1912, stat. nov. is brought out of synonymy and considered the valid name for “Phyllochlaenia Blanchard, 1846.” Warwickia, nom. nov. is proposed as a replacement name for the junior homonym Benedictia Sanderson, 1939 (non Dybowski, 1875) and consequently, Warwickia pilosa (Sanderson, 1939), comb. nov. is a new combination for the single species in this genus. A brief overview of the tribal classification of Melolonthinae is presented.

NAIR, S. S., BACHAN, K. H. A.  &  EBIN, P. J.  2021. Diversity and phenetic study on syconium of Ficus L. (Moraceae) from Kerala, India revealing natural classification along  with an identification key. Reinwardtia  20(1): 27–36. — Ficus L. commonly called ‘figs’ is one of the most complex genera among the angiosperms with its specialised inflorescence called syconium that looks like a fruit. Syconium of 33 species of  Ficus reported from Kerala were observed here to develop a novel key, solely based on syconium morphology. Numerical taxonomic methodology  for syconium  morphological characters  were standardised, considering 22 characters with 104 character states and analysed using similarity clustering. The floral features of the genus are very much complex and all the existing keys for the species identification relays on both vegetative as well as floral features. Hence, the present key will be practical  in  use  when  syconium  is  the  only  available  part.  The  numerical  analysis  of  the  syconium  features  well clustered and separated the trees with cauliflorous inflorescence, hemi epiphytic -epiphytic life forms and independent trees similar to the natural classification of the figs as  “Atthi, Itthi and Aal”, indicating that phenetic analysis using the syconium  characters  alone  provided  a  grouping  similar  to  the  natural  grouping  based  on  the  habit.  Preliminary phylogenetic analysis of figs also provided a similar clustering. This gives an insight into the fact that the separation of figs into these natural groups is reflecting phylogenetic trait. Detailed studies including more morphological traits and molecular analysis could establish the phylogenetic relation of figs in relation to the evolutionary history of climate and vegetation.

Narrow Endemics

Glossopetalon inhabits arid regions in the American west and northern Mexico on limestone substrates. The genus comprises four species: G. clokeyi, G. pungens, G. texense, and G. spinescens. Three of the species are narrow endemics. The fourth, G. spinescens, is a widespread species with six recognized varieties. All six varieties are intricately branched shrubs that have been difficult to identify due to a lack of clearly delineating morphological characters. Characters typically used to differentiate the varieties of G. spinescens, such as stem coloration, leaf blade size, and presence of stipules, are highly variable within and among populations. A custom protocol of double digest restrictionsite associated DNA sequencing (ddRAD) was used to resolve the phylogeny of Glossopetalon and address if population genetic data analyses (such as STRUCTURE, SVDquartets, and phylogenetic networks) support the recognition of six varieties of G. spinescens. Glossopetalon was fully supported as monophyletic and G. pungens was resolved sister to the remaining taxa in the genus. The varieties of G. spinescens were resolved as two distinct lineages corresponding to their biogeography, one to the northwest (lineage 1) and one to southeast (lineage 2) of the species range. Glossopetalon clokeyi was resolved at the base of lineage 1 and G. texense was embedded within lineage 2 sister to G. spinescens var. spinescens. Taxonomic changes include the recognition of G. texense and G. clokeyi as varieties of G. spinescens and description of a unique population from northern Arizona as a new variety, G. spinescens var. goodwinii.

First Time

The paederine genus Paederus s.l. (Coleoptera : Staphylinidae) is a hyperdiverse group of some 500 species worldwide. Although the subtribe Paederina, in which the genus resides, is monophyletic the status of numerous genera and subgenera is questionable and the current classification is likely to be flawed. As part of detailed studies on the paederine fauna of China, we undertook a preliminary morphologically-based phylogenetic analysis to determine the relationships of Paederus (Gnathopaederus) and related subgenera, as a basis for a revision of the subgenus, and as an attempt to provide a better framework for future taxonomic studies on the group as a whole. The analysis was based on 66 adult morphological characters for 30 ingroup taxa, including all six species of P. (Gnathopaederus). The results show that P. (Gnathopaederus) and P. (Paederus), and the genera Megalopaederus, Pachypaederus and Paederidus are monophyletic, and that P. (Eopaederus) and P. (Harpopaederus) are paraphylyetic. However, our analysis did not offer a robust solution to relationships among other clades within Paederus s.l. although it seems clear that Paederus s.l. is not monophyletic with respect to the above genera. The monophyly of P. (Gnathopaederus) is supported by the mandibular basal medial tooth having two cuspids separated dorsoventrally. Based largely on this character state, the definition of the subgenus is refined; six species are recognized, including two new species described from China as follows: P. (G.) daozhenensis, sp. nov. from Guizhou, and P. (G.) jilongensis, sp. nov. from Xizang; three species, P. bursavacua Willers, P. yunnanensis Willers and P. solodovnikovi Willers, are newly assigned to the subgenus according to a revised subgeneric definition. New morphological characters including important secondary sexual characters and sexual dimorphism are described and male genitalia are illustrated for the first time for the type species of the subgenus, P. (G.) szechuanus (Chapin). A key to the six species is presented and the distribution of each species is documented and discussed.

One New Species

The genus-level classification of New World Erythroneurini is revised based on results of a phylogenetic analysis of 100 morphological characters. The 704 known species are placed into 18 genera. Erasmoneura Young and Eratoneura Young, previously treated as subgenera of Erythroneura Fitch, and Erythridula Young, most recently treated as a subgenus of Arboridia Zachvatkin, are elevated to generic status. Three species previously included in Erasmoneura are placed in a new genus, Rossmoneura (type species, Erythroneura tecta McAtee). The concept of Erythroneura is thereby narrowed to include only those species previously included in the nominotypical subgenus. New World species previously included in Zygina Fieber are not closely related to the European type species of that genus and are therefore placed in new genera. Neozygina, n. gen., based on type species Erythroneura ceonothana Beamer, includes all species previously included in the “ceonothana group”, and Zyginama, n. gen., based on type species Erythroneura ritana Beamer, includes most species previously included in the “ritana group” of New World Zygina. Five additional new genera are described to include other previously described North American Erythroneurini: Hepzygina, n. gen., based on type species Erythroneura milleri Beamer and also including E. aprica McAtee; Mexigina, n. gen., based on type species Erythroneura oculata McAtee; Nelionidia, n. gen., based on type species N. pueblensis, n. sp., three additional new species, and Erythroneura amicis Ross; Neoimbecilla, n. gen., based on type species Erythroneura kiperi Beamer and one new species; and Illinigina, n. gen., based on type species Erythroneura illinoiensis Gillette. Five new genera, based on previously undescribed species, are also recognized: Aztegina, n. gen, based on A. punctinota, n. sp., from Mexico; Amazygina, n. gen., based on type species A. decaspina, n. sp., and three additional new species from Ecuador; Hamagina, n. gen., based on type species H. spinigera, n. sp., and two additional new species from Peru and Ecuador; Napogina, n. gen., based on type species N. recta, n. sp., and one additional new species from Ecuador; Perugina, n. gen., based on type species P. denticula, n. sp., from Peru; and Spinigina, n. gen., based on type species S. hirsuta, n. sp., and an additional new species from Peru. Phylogenetic analysis suggests that the New World Erythroneurini consist of three lineages resulting from separate invasions from the Old World.

The aim of the study is to develop the assessment technology and forecasting heterogeneity of regional incidence for differentiated healthcare management. Material and methods. The incidence of skin and subcutaneous tissue diseases in children aged 0–14 years in 2009–2017 in Russia was used as a material. The sources of information were the data of state statistics. Generally accepted statistical methods were used for the analysis. Results. The expressed heterogeneity of regions of the Russian Federation on children’s dermatological morbidity with a coefficient of variation of 28% is revealed. The marked size of heterogeneity steadily persisted in the 8-year follow-up. The stable predisposition of subjects to a certain rank place is proved. The territories were ranked according to the total 9-year rank. The classification of territories into types of low, medium and high risk of morbidity is carried out. Long-term stability of regional trajectories allows extrapolating them for prediction. Conclusion. The complex of statistical calculations forming the standard “forecast of regional heterogeneity technology assessment” is carried out. Used methods is universal and it could be used in assessment of any sign heterogeneity: morbidity, mortality, fertility, crime, unemployment, etc.

The generic classification of cicadas within the globally distributed tribe Cicadettini (Hemiptera: Cicadidae) has been challenging due to their often conservative morphology. A recent molecular analysis has indicated that the six North American taxa currently classified in Cicadetta are unrelated to the European type species of Cicadetta, C. montana Scopoli. Here we identify a set of diagnostic morphological characters for a new genus, which we distinguish from its closest relatives in Eurasia and Australasia.
