Abstract

<abstract abstract-type="main" id="syen12105-abs-0001"> <title>Abstract</title> <p id="syen12105-para-0001">The genera <italic>Pachymenes</italic> de Saussure and <italic>Santamenes</italic> Giordani Soika are revised and the phylogenetic relationships among their species, based on external morphology and male genitalia, are presented. The cladistics analysis, using 22 terminal species (19 ingroup and 3 outgroup species) and 44 characters, produced a single cladogram under implied weighting. Both genera were recovered as paraphyletic, althought two major clades were formed and were well supported by the re‐sampling analysis. We propose the synonymy of <italic>Pachymenes</italic> with <italic>Santamenes</italic>, and the description of two new species: <italic>P. saussurei</italic> Grandinete <bold>n.sp.</bold> and <italic>P. riograndensis</italic> Grandinete <bold>n.sp.</bold>. New combinations are: <italic>Pachymenes novarae</italic> (de Saussure) <bold>n.comb.</bold>, <italic>P. olympicus</italic> (Zavattari) <bold>n.comb.</bold>, <italic>P. peregrinus</italic> (Zavattari) <bold>n.comb.</bold> and <italic>P. santanna</italic> (de Saussure) revised combination. We state the synonymy of <italic>P. obscurus orellanoides</italic> under <italic>P. obscurus consuetus</italic>, reviewing the status of the latter and raising <italic>P. consuetus</italic> to species level. <italic>Pachymenes orellanae vardyi</italic> is synonymized under <italic>P. orellanae</italic>; <italic>P. ghilianii olivaceus</italic>, <italic>P. ghilianii flavissimus</italic> and <italic>P. peruanus</italic> are proposed as synonyms of <italic>P. ghilianii</italic>; <italic>P. picturatus obscuratus</italic> is synonymized under <italic>P. laeviventris</italic>; <italic>P. picturatus nigromaculatus</italic> and <italic>P. picturatus</italic> var. <italic>intermedia</italic> are synonymized under <italic>P. picturatus</italic> and <italic>P. atra</italic> var. <italic>ornatissima</italic> get its lectotype designated and proposed as synonym of <italic>P. ater</italic>.</p> <p id="syen12105-para-0002">This published work has been registered in ZooBank, <ext-link ext-link-type="uri" xlink:href="http://zoobank.org/urn:lsid:zoobank.org:pub:F1625D4F-B9D0-426D-9140-97E53A531F87" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">http://zoobank.org/urn:lsid:zoobank.org:pub:F1625D4F‐B9D0‐426D‐9140‐97E53A531F87</ext-link>.</p> </abstract>
