“…The genus Schismatothele was also originally based only on a female holotype and had the male specimen described for the first time in 2011, with the species Schismatothele benedettii Panzera et al . (). The authors showed its swollen tibia bearing strong spines on the retrolateral face and the pyriform palpal bulb with small keels.…”

Guadanucci, J.P.L. (2014). Theraphosidae phylogeny: relationships of the 'Ischnocolinae' genera (Araneae, Mygalomorphae). -Zoologica Scripta, 43, 508-518. The mygalomorph spider subfamily 'Ischnocolinae' was originally established as a group based on the presence of divided tarsal scopula. Later, the divided condition of the scopula was considered the plesiomorphic state, which could not support the monophyly of 'Ischnocolinae'. In Raven 1985, the subfamily was considered paraphyletic, pending a phylogenetic analysis to reinvestigate monophyletic groups. This study comprises such a phylogenetic analysis, based on morphological data, that includes representatives of all genera currently included in 'Ischnocolinae' as well as representatives of all other nine Theraphosidae subfamilies (Thrigmopoeinae, Ornithoctoninae, Eumenophorinae, Stromatopelminae, Harpactirinae, Selenogyrinae, Theraphosinae, Aviculariinae and Selenocosmiinae). The family Theraphosidae is considered monophyletic and expanded to include three additional genera previously considered as possible Barychelidae, namely Brachionopus (as Harpactirinae), Trichopelma and Reichlingia (as Ischnocolinae sensu stricto) while 'Ischnocolinae' as previously defined does not appear as monophyletic. However, two monophyletic groups were defined as subfamilies to include some former 'Ischnocolinae' representatives. The first group includes Acanthopelma rufescens, Trichopelma nitidum, Reichlingia annae, Ischnocolus spp., Holothele rondoni, Holothele culebrae and Holothele aff culebrae and is hereby named as Ischnocolinae (sensu stricto). The other subgroup comprises Sickius longibulbi, Holothele incei, Holothele aff incei, Guyruita spp., Schismatothele lineata, Hemiercus modestus, Holothele colonica and Holothele sp., together established as Schismatothelinae subfam. nov. Several genera included in former 'Ischnocolinae' appear as monophyletic (Catumiri, Oligoxystre, Heterothele, Nesiergus, Chaetopelma, Ischnocolus, Guyruita and Plesiophrictus). However, the genera Holothele, Schismatothele and Hemiercus deserve more attention in order to evaluate their intrarelationships and inclusion of species.

“…However, the relationships of the two genera within the family Theraphosidae is still uncertain. Panzera et al (2011), arguing in favor of a conservative perspective, maintained the genus Schismatothele in Theraphosinae, even though they lack two of the three synapomorphies of the subfamily (keels on palpal bulb, abdominal urticating hairs), presenting only an extended subtegulum. They considered the keels on the bulb of Schismatothele not homologous to the keels of Theraphosinae.…”

“…Today, the genus Hemiercus comprises five species: H. inflatus, H. cervinus, H. modestus, H. proximus and H. kastoni. After the revalidation of the genus Schismatothele by Rudloff (1997), Panzera et al (2011) described the new species, S. benedettii, from Brazilian amazon forest and the male representative of the genus was described for the first time, albeit not of the type species. The authors presented important characters related to male genitalia to warrant recognition of the genus.…”

The genus Euthycaelus Simon 1889 is diagnosed based on the examination of type-material and additional material from Venezuela and Colombia. The genus now includes: Euthycaelus colonicus Simon 1889, E. norae sp. nov., E. amandae sp. nov.; Euthycaelus steini Simon 1889 is transferred to Psalistops comb. nov. The genus Schismatothele Karsch 1879 is considered a senior synonym of Hemiercus Simon 1903. Schismatothele includes S. lineata Karsch 1879, S. inflata (Simon 1889) comb. nov., S. modesta (Simon 1889) comb. nov, and S. benedettii Panzera et al. 2011. Hemiercus proximus Mello-Leitão 1923, from Cubatão, São Paulo, Brazil, is transferred to Acanthoscurria proxima (Mello-Leitão 1923) comb. nov. Hemiercus kastoni Caporiacco 1955 is considered a species inquirenda pending the examination of the type material.

Seven new species of Schismatothele Karsch, 1879 (Araneae, Theraphosidae) are described, almost doubling the diversity of the genus: S. caeri sp. nov.; S. caiquetia sp. nov.; S. merida sp. nov.; S. moonenorum sp. nov.; S. quimbaya sp. nov.; S. timotocuica sp. nov. and S. wayana sp. nov. An identification key for all species of Schismatothele (except S. kastoni) is presented, as well as a complementary diagnosis for the genus. Also, a standardized nomenclature is proposed to describe the prolateral keels of male palpal bulbs of species of Schismatothele.
