Vitsika Singularis
''Vitsika'' is a Malagasy genus of ants in the subfamily Myrmicinae. Described in 2014, the genus contains 14 species. Description Queens are known for all species except ''V. obscura''. The queens may be alate or ergatoid, or both forms may occur within a single species. It is possible that all species will be found to produce both ergatoids and alates when the species are better represented in collections. Two species (''V. manifesta'', ''V. suspicax'') exhibit morphological intermediates between alate and ergatoid forms, and two species (''V. acclivitas'' and ''V. crebra'') appear to be polygynous. Worker-associated males are known for ''V. crebra'', ''V. breviscapa'' and ''V. labes''. In addition, the males of three other species, collected in isolation (in Malaise traps), are present in collections. Similar in size to the conspecific worker or slightly smaller.

Barry Bolton
Barry Bolton is an English myrmecologist, an expert on the classification, systematics, and taxonomy of ants, who long worked at the Natural History Museum, London. He is known especially for monographs on African and Asian ants, and for encyclopaedic global works, including the ''Identification Guide to Ant Genera'' (1994), ''A New General Catalogue of Ants of the World'' (1995, updated in 2007), ''Synopsis and Classification of Formicidae'' (2003), and ''Bolton's Catalogue of Ants of the World: 1758-2005'' (2007). Now retired, Bolton is a Fellow of the Royal Entomological Society The Royal Entomological Society is a learned society devoted to the study of insects. It aims to disseminate information about insects and to improve communication between entomologists.

The term polygyny is from Neoclassical Greek πολυγυνία (); . Incidence Polygyny is more widespread in Africa than in any other continent. Some scholar ....

Hymenoptera Of Africa
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they reach adulthood. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ant Genera
Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from vespoid wasp ancestors in the Cretaceous period. More than 13,800 of an estimated total of 22,000 species have been classified. They are easily identified by their geniculate (elbowed) antennae and the distinctive node-like structure that forms their slender waists. Ants form colonies that range in size from a few dozen individuals often living in small natural cavities to highly organised colonies that may occupy large territories with sizeable nest that consist of millions of individuals or into the hundreds of millions in super colonies. Typical colonies consist of various castes of sterile, wingless females, most of which are workers (ergates), as well as soldiers (dinergates) and other specialised groups. Nearly all ant colonies also have some fertile males called "drones" and one or more fertile females called "queens" (gy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year, this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of p ...
