Tribe Lutosini Gorochov, 1988

Comments. This subfamily/tribe was initially described as a subfamily of Mimnermidae (= Anostostomatidae ), including only Lutosa ( Gorochov, 1988) . Johns (1997), defined the family Anostostomatidae and divided it into two subfamilies, Anostostomatinae and Deinacridinae. The subfamilies defined by Gorochov (1988), are treated mostly as tribes in Anostostomatinae . Therefore, Lutosini got its tribal status. Johns (1997) also included additional genera in the tribe, such as: Licodia , Apotetamenus , Libanasa , Papuaistus , Carcinopsis Brunner von Wattenwyl, 1888 , Aistus Brunner von Wattenwyl, 1888 , Spizaphilus Kirby, 1906 , Hypocophus Brunner von Wattenwyl, 1888 and Hypocophoides Karny, 1930 . Issa & Jaffe (1999) described Hydrolutos from the imposing Tepuis of Venezuela, this genus is remarkable for its semi-aquatic habits.

In 2001, Gorochov proposed a classification for the superfamily Stenopelmatoidea and, consequently, for Anostostomatidae , giving subfamily status again to those taxa proposed by him in 1988 and adding Leiomelinae as a new subfamily. In the particular case of Lutosinae , it only maintained Lutosa , and, Apotetamenus and mentioned that Licodia might belong to this subfamily ( Gorochov 2001a). In the same year, Gorochov described the genus Neolutosa (with two species), and three Lutosa species from Brazil ( Gorochov 2001b). Derka and Fedor described additional species for Hydrolutus when exploring new Tepuis in Venezuela ( Derka & Fedor 2010, 2012, Derka et al. 2013, 2016).

Cadena-Castañeda & Cortés-Torres (2013) described Apotetamenus gorochovi Cadena-Castañeda & CortésTorres, 2013 , and synonymized Apotetamenus politus (Bruner, 1915) under Apotetamenus clipeatus Brunner von Wattenwyl, 1888 . In 2015, the location of Libanasa in Lutosinae was discussed. The difficulty of defining the subfamily due to the included taxa’s morphological variability is evidenced. It was suggested that the diversity of Neotropical taxa known at that time was reviewed to understand group’s diversification, compared to taxa from other regions of the world ( Johns 1997, Johns & Hemp 2015). Heleodoro & Mendes (2016) describe Lutosa horribilis , highlighting the bad smell expelled by individuals of this species; additionally, they record the genital characteristics, this being an important piece of information to establish differences between Lutosinae taxa. Recently, new genera have been described for Lutosinae / Lutosini , such as Rhumosa , distributed in the Lesser Antilles and morphologically very similar to Lutosa ( Hugel & Desutter-Grandcolas 2018) . Tintiyakus was also recently described as morphologically very similar to Hydrolutos , being its Amazon lowland counterpart ( Mendes et al. 2020).

Finally, Gorochov (2020) proposed a new classification for the Stenopelmatoidea , which goes against his 1988 and 2001 proposals. He makes significant changes to all the taxa of the superfamily. But focusing on Anostostomatidae , he divided the family into only two subfamilies, Lezininae and Anostostomatinae ; in the latter, he included all those subfamilies that he proposed in the past under tribe status, and thus Lutosinae become the tribe Lutosini .
