Etymology. The specific epithet refers to the Andean ethnic group known as “Quéchua” or “Runakuna”, speakers of the Quechua language. Native inhabitants of the Andean region, mainly in Peru and Bolivia. Noun in apposition.
Differential diagnosis. Podisus quechua sp. nov. is similar to Podisus distinctus Stål , differing by the shorter humeral angles, and the anterolateral margins of pronotum not tumescent as in P.distinctus (see a redescription in Brugnera et al. 2020). In addition, the paremeres are spatulated in P.quechua , and bifurcated in P.distinctus . The posterior angle of valvifers VIII are projected and acute in P. quechua , whereas not projected and rounded in P.distinctus . Also, they are parapatric, with P.quechua occurring in the Andean region (Peru, Bolivia), and P.distinctus with records in the Atlantic Rainforest in Brazil ( Brugnera et al. 2020).
Description. Coloration: Head, pronotum, scutellum, and coria with predominance of brown punctures, interspaced by light-brown areas. Anterolateral margins of pronotum with a pale and unpunctured outline. Ventral surface light-yellow, with dark brown punctures. Legs pale yellow, without spots. Hemelytral membranes present a fumose spot medially. Anterior and posterior regions of connexival segments dark brown, middle light yellow. Head: Mandibular plates and clypeus subequal in length. Proportions of antennomeres: 1 <2> 3 <4> 5. Apex of labiomere 4 reaches anterior margin of metacoxae. Proportions of labiomeres: 1 <2> 3> 4. Thorax: Anteriolateral angles of pronotum projected, anterolateral margins crenulated. Humeri developed, acute, with a posterior protuberance. Peritreme of ESES ruga-shaped, reaching half of metapleural width. Evaporatorium surrounding peritreme, not reaching metapleural outer margin, extending to posterior angle of mesopleura. Apex of coria reaches urosternite VI and hemelytral membranes surpass posterior abdominal margin. Abdomen: Urosternite III has a median spine, which reaches metacoxae. Posterior angles of urosternite VII acute. Male genitalia: Pygophore cup-like. Posterior opening subtriangular. Dorsal rim concave and projected medially. Inferior layer of ventral rim concave, superior layer sinuous. Head of parameres spatulated. Pseudoclaspers rugulose dorsally. Female genitalia: valvifers VIII subtriangular, posterior margins sinuous, forming a V-projection on posterior angles, sutural margins rectilinear. Exposed portion of laterotergites IX tongue-like. Laterotergites VIII triangular with spiracles on proximal angle. Exposed portion of valvifers IX rectangular, wider than long.
Distribution. Bolívia (La Paz), Peru (San Martín) ( Fig. 11 View Fig ).
