A New Species and a New Synonymy of the Neotropical Genus Seridentus Osborn (Hemiptera: Reduviidae: Stenopodainae)

Description of the Second Species of Nogullocoris Miller, 1958 (Hemiptera: Reduviidae: Stenopodainae) and Adjustments to the Taxonomic Concept of the Genus

“…Pronotum (Figs 4, 5) subtrapezoid, 1.7 times as broad as length along midline; anterior margin broadly concave, anterolateral angle protruding anterolaterally with apex acute; anterior lobe slightly shorter than posterior lobe, weakly inflated dorsally; posterior lobe 1.7 times as broad as anterior lobe, with two pairs of weak submedian carinae on disc (Fig. 4); lateral margin armed with one row of small setigerous tubercles (Figs 4, 5); humeral angle strongly protruding laterally with apex acute (Figs 4, 6); posterior margin slightly concave at midportion (Fig.…”

“…Pedionotocoris differs from Nogullocoris by having the longer antennal scape (distinctly longer than the anteocular) and the strongly and foliaceously expanded abdominal connexivum. The relative length of the antennal scape has been used as a species-level distinguishing character in some genera of Stenopodainae, for instance, Pygolampis Germar, 1825 (Hsiao & Ren 1981, Putshkov & Moulet 2010 and Seridentus Osborn, 1904(Chen et al 2022. Likewise, the shape of the abdominal connexivum may vary considerably within the same genus (Bérenger & Maldonado 1996, Bérenger 2001.…”

“…Rorocoris has the same relatively short antennal scape as Nogullocoris, but the lateral margin of the pronotum lacks tubercles and the humeral angle of the pronotum is rounded. However, these two-character states have been used to distinguish different species within many stenopodaine genera (e.g., Barber 1930, Villiers 1968Linnavuori 1976, Chen et al 2022.…”
