Podisus bororo Brugnera & Sampaio & Campos & Grazia 2024, sp. nov.

Podisus bororo Brugnera & Grazia, sp. nov. (Fig. 8) ZooBank: https://www.zoobank.org/8615E169-9371-4BE7-A10F-6451DA4099E3 Type material. Holotype: ♂, Faz.Cachoeirinha, Jataí, Goiás – Brasil (-17.8913, -51.7263), X.1962, Exp. Dep. Zool. (MZSP). Etymology. The specific epithet refers to the ethnic group known as Bororo (Boe by self-denomination), native inhabitants of the current states of Mato Grosso, Mato Grosso do Sul, and Goiás in Brazil, and western Bolivia. Noun in apposition. Differential diagnosis. Podisus bororo sp. nov. is similar to Podisus falcatus and Podisus semialbus, members of the falcatus group (sensu Thomas 1992). Additionally, is particularly similar to Podisus guarani sp. nov., here described. The falcatus group (except P. curvispina) can be distinguished from its congeners by the long and posteriorly developed humeral angles of the pronotum, including the presence of a distinct posterior tooth; and the pale to light-yellow coloration of urosternites. The four species (P.falcatus, P.semialbus, P.Bororo sp. nov., and P.guarani sp. nov.) can be differentiated by the size of the band following the anterolateral margins of pronotum, and the coloration of the ventral surface. Podisus bororo is unique within the falcatus group in having the band in the pronotum anterolateral margins narrower (in dorsal view), combined with the brown coloration of the lateral half of propleura, mesopleura and metapleura (Fig. 8b–e) Description. Coloration: Head, pronotum, scutellum, and coria with predominance of brown punctures, interspaced by light brown areas. Anterolateral margins of pronotum with a narrow light yellow outline. Antennomere I is light yellow, antennomeres II–V are missing, and labium is light yellow. Urosternites, medial region of propleura, mesopleura, and metapleura are light yellow and lateral half of propleura, mesopleura, and metapleura are brown. Legs are light yellow. Hemelytral membranes have a fumose spot medially. Connexival segments are brown, with lateral margins light yellow. Head: Mandibular plates and clypeus subequal in length. Apex of labiomere 4 surpasses posterior margin of metacoxae. Proportions of labiomeres: 1 <2> 3> 4. Thorax: Anterolateral margins of pronotum crenulated. Humeri developed upward, acute, posteriorly directed, with a posterior protuberance. Peritreme of ESES is ruga-shaped, reaching half of metapleural width. Evaporatorium surrounding peritreme, not reaching metapleural outer margin, extending to posterior margin of mesopleura, reaching posterior angle. Apex of coria reaches urosternite VI, and hemelytral membranes surpass posterior abdominal margin. Abdomen: Urosternite III has a minute spine, which does not reach metacoxae. Posterior angles of urosternite VII developed and acute. Male genitalia: Pygophore cup-like. Posterior opening oval. Dorsal rim concave, with 1 + 1 projections. Inferior layer of ventral rim concave, superior layer sinuous and depressed medially. Head of parameres with posterior margins concave, anterior branch rounded and posterior branch elongated, finger-like. Pseudoclaspers with few rounded protuberances. Female: unknown. Distribution. Brazil (Goiás) (Fig. 11). Measurements. Total length: 6.3; head length: 1.3; head width: 1.5; pronotum length: 1.8; pronotum width: 6.4; scutellum length: 2.5; scutellum width: 2.4; abdominal length: 3.0; abdominal width: 3.5; length of antennomeres: I 0.3; II–V missing; length of labiomeres: I 0.8; II 1.1; III 0.8; IV 0.5.
