Albert Tullgren
Hugo Albert Tullgren (7 September 1874, in Stockholm – 1 July 1958) was a Swedish entomologist and arachnologist. In 1899 he received his bachelor's degree from Uppsala University, then from 1902 worked as an assistant at the National Entomological Institute. From 1907 he was associated with the entomology department of the ''Centralanstalten för försöksväsendet på jordbruksområdet'' (Central Institute for Experimental Agriculture), of which, he became a professor in 1913. The jumping spider genus '' Tullgrenella'' was named in his honor by Cândido Firmino de Mello-Leitão. The eponymous "Tullgren funnel" is a modified Berlese funnel, a device used to extract small insects and arthropods from soil samples.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
