Here Schizopteridae is registered for the first time in Paraná State with the record of four species, being one to generic level,Glyptocombus sp. The three nominal species recorded are: Schizoptera (Schizoptera) apicalis Reuter, 1882, Schizoptera (Cantharocoris) reitteri Reuter, 1891, and Ptenidiophyes mirabilis Reuter, 1891, all only recorded from type locality. The Schizopteridae fauna of Brazil is now composed of 22 nominal species in 13 genera, recorded in nine Brazilian states, plus the genus Glyptocombus recorded in the South and Southeast regions of the country. Keywords: Distribution, jumping bug, minute litter bug, Neotropical fauna. The Schizopteridae are minute Heteroptera with 0.8 to 2.0 mm, Zeiss AxioCam Mrc. The specimens are deposited in the “Museu comprising specimens with large eyes, well-developed ovipositor Regional de Entomologia” (UFVB) and “Coleção de Invertebrados do and labium with four segments; or specimens withsmaller eyes and Instituto Nacional de Pesquisas da Amazônia” (INPA). reduced ovipositor (Knyshov et al. 2016; Schuh & Weirauch 2020). The biology of this family is not well known, with some species appearing Subfamily Schizopterinae to be predatory and predominantly found in moist soil and litter in Schizoptera (Schizoptera) apicalis Reuter, 1882 tropical forest regions (Schuh & Weirauch 2020). Because of the cryptic habits and small size of species, these soil bugs have been overlooked Specimens of S. (S.). apicalis can be distinguished by anterior by collectors and poorly studied, mainly in tropical countries cross vein almost at apex of discal cell, well separated from posterior (Wygodzinsky 1947; Emsley 1969; Weirauch 2012). Schizopteridae has cross vein and scutellum with two depressed shining spots, and male two subfamilies (sensu Schuh & Weirauch 2020): Hypselosomatinae subgenital plate with two lateral projections, proximal projection known from the Indo-Pacific, Australian and Neotropical regions; and curved and acute and distal projection square (Fig. 1A). This last Schizopterinae, with a worldwide distribution (McAtee & Malloch characteristic corresponds to drawing of McAtee & Malloch (1925). 1925; Emsley 1969; Weirauch 2012). Currently, Schizopteridae is the In the key of McAtee & Malloch (1925) the species Schizoptera largest family of Dipsocoromorpha, with ~60 genera and about 355 (Schizoptera) flavipes Reuter, 1882 was absent, but it can be excluded described species (Weirauch 2012; Weirauch et al. 2018). However, it from consideration on the basis of anterior cross vein position as in is estimated that there may be about 1,200 species of Schizopteridae Reuter (1891). In Brazil two species of Schizoptera (Schizoptera) have in the world, especially in the Neotropics, where the fauna is poorly been recorded: S. (S) flavipes from Rio de Janeiro State and S. (S.) studied (Weirauch 2012). apicalis (Fig. 1A) from Pernambuco State. The species S. (S.) apicalis is In addition, the taxonomy and distribution of most species are now recorded from Paraná State, Southern Brazil (Tab. 1). poorly unknown (Emsley 1969; Weirauch 2012). In Brazil, for example, Examined material. 3 males and 10 females (UFVB and INPA): for more than 60 years only 11 schizopterid species were recorded from 03.vii.2009, NG Cipola leg. the states of Pernambuco, Rio de Janeiro and Santa Catarina (Emsley 1969). Recently one new genus and species was described from São Schizoptera (Cantharocoris) reitteri Reuter, 1891 Paulo State (Hoey-Chamberlain & Weirauch 2016), one species from Schizoptera (C.) reitteri (Fig. 1B), is recognized by ocelli absent, veins Rio Grande do Sul State (Silveira et al. 2019), and more nine new of fore wing distinctly elevated, clavus long with sutural margin more species for the Brazilian Amazon (Knyshov et al. 2016; Almeida et al. than three times as long as scutellum, no cross vein in forewing near 2019a, 2019b, 2020; Weirauch et al. 2020), raising to 22 species in 13 apex of clavus as in the key of McAtee & Malloch (1925) and Emsley genera recorded in Brazil. The objective of this work is to expand the (1969). This species was previously known only from the type locality, Schizopteridae geographic distribution in Southern Brazil.

However, the distribution of this species is extended here to (23°09’00”S, 50°34’22”W), located in a fragment of 832.58 hectares of Paraná State (Tab. 1). semi-deciduous forest, between the municipalities of Santa Mariana and Cornélio Procópio, Northern Paraná State, Brazil.
