ABSTRACT
New diagnostic characters were used to study the genus Litoblatta Hebard: paraprocts, styles due to their shape and distribution of spines, and sclerites of the genitalia of the male with emphasis on the right complex. Male and female genitalia are described in detail. Four new species of cockroaches are described, Litoblatta elisae, Litoblatta lutea, Litoblatta misionerae, and Litoblatta tucumanae. The number of species recorded for Argentina rises to 7 and a key for male determination is provided. The geographic distribution of the studied species of cockroaches is extended.

The genus Lanta Hebard 1921 includes three species found in the Neotropical region. Two species are known from Argentina, L. peniculiger (province of Santa Fe), and L. scotia (provinces of Córdoba and Santiago del Estero) (see Crespo et al. 2010), and one from Brazil, L. borgesae, (Araras, São Paulo) (Rocha e Silva & Vasconcellos, 1984). All species have been described on the basis of male external characters, such as wing veins, leg spines, hypandrium, shape and position of the styli, in addition to coloration and size. Except for a partial representation of the male genitalia of L. borgesae (Rocha e Silva & Vasconcellos 1984), this structure went untreated in morphological and phylogenetic investigations of the Blattaria (Snodgrass 1937; McKittrick 1964; Grandcolas 1996; Klass 1997; Roth 2003;). Females remain unknown.

The number of species of the genus Ischnoptera reported from Uruguay is doubled, increasing its number to 6. Ischnoptera argentina Hebard, 1921; I. bilunata Saussure, 1869; and I. litostylata Hebard, 1921 are reported for the first time. The available information on the species distribution is mapped.
