Most recently, Coimbra et al. (2020) published an article in this journal (Zootaxa, 4729 (2) 177-194) questioning the taxonomic position of the genus Copytus Skogsberg, 1939 (Crustacea, Ostracoda) along with proposing it as the type genus of their new family (Copytidae Coimbra et al., 2020), and erecting two new species that were listed by previous authors as Copytus sp. 1 and Copytus sp. 2. The main diagnostic characteristics of their new proposed family (and the genus Copytus) are the hinge type and muscle scars on the carapace and/or valves (see lines 6-8 from the bottom, p. 179 in Coimbra et al. 2020). find more They also underlined that (p. 179) "...this study is based exclusively on the morphology of the animals' hard parts". While the authors considered another genus (Neocopytus) proposed by Külköylüoğlu, Colin Kılıç (2007) of the family Neocytherididae as invalid, they interestingly transferred some species of Neocopytus to Copytus as species of their new family (Coimbra et al. 2020). Herein, my point with the comments listed below is to clarify that, when possible, both soft and hard parts should be considered in taxonomy, and such an integrated approach clearly indicates that Neocopytus is a valid and taxonomically useful genus.The family Theraphosidae is the most speciose in the infraorder Mygalomorphae Pocock, 1892 with over one thousand described species (World Spider Catalog 2021). The taxonomy of the group has been subjected to considerable attention in modern times, with a focus on delineation based predominantly on genital organ and stridulatory organ morphology which has shown promise, both alongside molecular methods (where possible) and as a stand-alone line of evidence, in stabilising the group (e.g. Hamilton et al. 2016; Fabiano-da-Silva et al. 2020; see also Sherwood 2020). The predominant reference to the family is as Theraphosidae Thorell, 1870 with almost as many references to Theraphosidae Thorell, 1869. This non-congruence of dates is because Tord Tamerlan Teodor Thorell (1830-1901) had his important work On European Spiders published in two parts during its publication by the Royal Society of Upsala in its journal Nova Acta Regiae Societatis Scientiarum Upsaliensis. The first half (pages 1-108 and the supplement I-XIII) was published in 1869 whereas pages 109-242 (despite being dated on the cover page as 1869) were published in 1870 (see Roewer 1942; Bonnet 1945; World Spider Catalog 2021). In the second part, the secretary of the society notes "L'auteur avait proposé comme titre du présent mémoire Remarks on Synonyms of European Spiders, preceded by some observations on Zoological Nomenclature and a Review of the European Genera of Spiders; mais, la partie, insérée dans le Tome VII, étant seule présentée à la Société des Sciences le 13 Fevr. 1869, il a été nécessaii'e d'y conformer le titre." [= The author proposed as the title of this memoir Remarks on Synonyms of European Spiders, preceded by some observations on Zoological Nomenclature and a Review of the European Genera of Spiders; but, the part, inserted in Volume VII, being the only one presented to the Société des Sciences on 13 Feb. 1869, it was necessary to conform the title to it.].The genus Tzustigmus Finnamore (Crabronidae Pemphredoninae) from India is reviewed and a modified key to the world species is provided. A new species T. sahyadriensis Tessy, Girish Kumar Sureshan sp. nov., from Kerala is described and illustrated.Aberrasine pangsau, sp. nov. is described as a new from Shergaon, Arunachal Pradesh, North East India. The new species is diagnosed with its closely similar species, A. strigivenata (Hampson, 1894). Additionally, we divide the genus into two species groups and provide the world checklist of the genus.Many genus-level changes to the classification of Trochilini were enacted in Stiles et al. (2017b). We have since found that two further genera therein emended each require replacement names. The first of these requir
