description: <i>Parvindela</i> Duran and Gough, new genus (Fig. 2) <b>Etymology.</b> The generic name is derived from <i>Parv</i> - (Latin root meaning “small”) and <i>Cicindela</i> (the type genus of the tribe Cicindelini); gender is feminine. <i>Parvindela</i> adults are small (7–12 mm), and the genus includes some of the smallest tiger beetles in the Nearctic region. <b>Type species.</b> <i>Cicindela debilis</i> Bates, 1890; by present designation <i>Parvindela debilis</i> (Bates, 1890), new combination <b> <i>Parvindela celeripes</i> (LeConte, 1848), new combination</b> <b> <i>Parvindela cursitans</i> (LeConte, 1860), new combination</b> <b> <i>Parvindela terricola</i> (Say, 1824), new combination</b> <b> <i>Parvindela nephelota</i> (Bates, 1882), new combination</b> <b> <i>Parvindela lunalonga</i> (Schaupp, 1884), new combination</b> <b>Description.</b> Small size, 7–12mm. Body shape variable, with humeral region narrow and ant-like (e.g., <i>P</i>. <i>celeripes</i>) to more robust (e.g., <i>P</i>. <i>terricola</i>). Head with fine rugosity present in supraorbital region. Frons glabrous except for supraorbital setae. Proepisternum glabrous or with only a few scattered setae near margins. Marginal line, if present, typically not fully touching outer edge of each elytron. No single morphological synapomorphy has been identified that unites <i>Parvindela</i>, but this new genus is strongly supported by recent phylogenetic studies (Gough et al. 2019; this study), previously recognized as a subgroup of <i>Cylindera</i>. The genus <i>Cylindera</i> initially included only Palearctic species, but in Rivalier’s (1954) revision of <i>Cicindela</i> (<i>s</i>. <i>l</i>.) the genus was amended to include American species that possessed aedeagi with similarly wound flagella. He noted that there were a number of inconsistencies and “aberrant” species but did not believe it was necessary to name a genus for the American species. The phylogeny of Gough et al. (2019) recovered a polyphyletic <i>Cylindera</i>, with each clade found in a particular biogeographic realm. A monophyletic clade of Nearctic species was part of a larger Nearctic endemic clade that also included <i>Ellipsoptera</i> and <i>Dromochorus</i>. This previously unnamed lineage that is now designated as <i>Parvindela</i>, new genus. <b>Distribution.</b> Nearctic region (Canada, USA, Mexico). To date, all known species are found within this biogeographic realm. All of the above listed species were included in Gough et al. (2019) and/or this study.
