Remarks. Peltidocylapus as here defined is most like Valdasus Stal in sharing the character of the metathoracic ostiolar peritreme characteristic of being oval, relatively broad, and moderately raised above the evaporative areas. In Amapacylapus and Cylapus , the ostiolar peritreme is strongly raised above evaporative area and is either narrow and ear-like ( Amapacylapus ) or arcuate and sharply pointed ( Cylapus ) ( Wolski 2017; Wolski et al. 2020). Peltidocylapus can be easily distinguished from Valdasus by the pronotum being covered with short, recumbent or semi-recumbent setae (erect and long in Valdasus ) and the impunctate mesepimeron (rugo-punctate or punctate in Valdasus ). Both the equally weighted and the implied weight analyses presented in this paper recovered a grouping composed of taxa belonging to Peltidocylapus and Valdasus , and the IW analysis showed a sister group relationship of both genera ( Fig. 2 View FIGURE 2 ). In contrast, the EW analysis recovered a polyphyletic Peltidocylapus and an unresolved position of Valdasus ( Fig. 1 View FIGURE 1 ), which casts doubt on the taxonomic arrangement presented in the present paper. In this scenario Peltidocylapus spinosus sp. nov. receives an uncertain position within the clade Peltidocylapus + Valdasus . This is the only analyzed Peltidocylapus species having the endosoma with the sclerites ( Fig. 14r View FIGURE 14 ). Remaining taxa included in the analysis possess an endosoma without sclerites ( Figs 12j View FIGURE 12 , 13a View FIGURE 13 ) and this character was shown to unite these species in the EW analysis ( Fig. 2 View FIGURE 2 ). Unfortunately, I was not able to study the female and male genitalia of P. cerbereus , P. festinabundus , P. nubilus , P. picatus or P. politus , and therefore they were not included in the analysis. Future exploration of the genitalic structures of these taxa will give more complete data and allow for better understanding of the relationships within Peltidocylapus and providing a more stable classification of the genus.
