“…10A-C). Levi (1954b;1964b) and Levi and Levi (1962) report the presence of humps in the opisthosoma as a diagnostic character, however, we recognize that some species lack humps ( Fig. 8A-B), therefore this character would not be useful to diagnose all Chrosiothes species.…”

The monophyly of Spintharinae is supported in agreement with previous analysis of Theridiidae by Agnarsson and Arnedo et al. We study the relationships of the genera within Spintharinae. Fourteen species in the genera Chrosiothes, Episinus, Spintharus, Stemmops, and Thwaitesia constituted the ingroup, while five species from the genera Euryopis and Dipoena (Hadrotarsinae), as well as Latrodectus and Steatoda (Latrodectinae), served as outgroup taxa. The character matrix included 49 morphological characters. Parsimony analyses using several character weighting strategies supported the monophyly of Spintharinae with Stemmops as sister to a clade that includes the remaining ingroup taxa. Chrosiothes emerged as sister to Episinus + Spintharus + Thwaitesia which formed a polytomy. The equally weighted, successive weighted, and preferred implied weight topologies, were all logically consistent. A key to the genera of Spintharinae and diagnoses for each genus are given.

“…Levi (1957), in a paper on the genera Crustilina and Steatoda, combined the genera Asagena, Lithyphantes, and Teutana into the genus Steatoda, a revision which is followed here. Steatoda has over 100 described species (about 40% of which were described before 1920 and have not been revised since), found in all parts of the world.…”

Four theridiid spiders of the genus Steatoda are present in New Zealand: S. truncata (Urquhart) 1887 and S. lepida (Cambridge) 1879, which are endemic; S. grossa (Koch) 1838, a cosmopolitan species; and S. capensis Hann, 1990, a South African species. The synonymy of S. regia (Marples) 1956 with S. lepida is recognised. Theridium truncatum Urquhart, 1887 is recognised as a valid species within Steatoda, and the male is described here for the first time. The four species are described, diagnostic features illustrated, and ecological information given where possible. A fifth record, for S. nubilosa Urquhart, 1892, is rejected.

“…The type species of the genus, E. truncatus Latreille, 1809, was described from Italy. The last taxonomic of Episinus from the Neotropical region was made by Levi (1955), who proposed 26 species for this region. Levi (1964; and Buckup & Marques (1992) increased to 37 the number of Neotropical species.…”

The spider family Theridiidae Sundevall, 1833 is currently represented by 121 genera and 2,387 species distributed worldwide (Platnick, 2014), of which 52 genera are recorded in the Neotropical region. The genus Episinus Latreille, 1809 has 57 described species but only 29 (50.8%) are known by both sexes (Platnick, 2014). The type species of the genus, E. truncatus Latreille, 1809, was described from Italy. The last taxonomic of Episinus from the Neotropical region was made by Levi (1955), who proposed 26 species for this region. Levi (1964; 1967) and Buckup & Marques (1992) increased to 37 the number of Neotropical species. Later, 13 species were removed from Episinus, where seven species were transferred to the genus Neopisinus (Marques et al., 2011) and six species to the genus Janula (Yoshida & Koh, 2011). Currently, 24 species have been recorded from the Neotropical region, almost 40% of the known species in the world.
