Abstract

The taxon Securiops Jacobus, McCafferty& Gattolliat 2006 is treated here as a subgenus of the genus Procloeon Bengtsson 1915; it shares all characters of Procloeon s.l. and besides them, has peculiar autapomorphies in mouthparts structure. Diagnoses of Cloeon/fg1 (or the tribe Cloeonini sensu Kluge 2016), Procloeon/g1 (or the genus Procloeon sensu Kluge 2016) and Securiops are given. Larvae of the South African species Procloeon (Securiops) falcatum (Crass 1947) comb. n. are described for the first time. Based on reared specimens from Zambia, larvae of Procloeon (Securiops) macafertiorum Lugo-Ortiz (in Lugo-Ortiz & McCafferty) 1996 are redescribed; subimagines, imagines and eggs of this species are described for the first time. New larval characters of Procloeon (Securiops) mutadens (Jacobus et al. 2006) comb. n. are reported based on a larva from Gambia. Based on reared specimens from Thailand, larvae of Procloeon (Securiops) primasia (Kaltenbach et al. 2023) comb. n. are redescribed; subimagines, imagines and well-developed eggs of this species are described for the first time. Genitalia of Cheleocloeon excisum (Barnard 1932) are figured for the first time.

摘要

本文将麦卡弗蒂和加托利亚特 2006 年建立的分类单元 Securiops Jacobus 作为 Procloeon Bengtsson 1915 的一个亚属来处理；它具有 Procloeon s.l. 的所有特征，此外，在口器结构上还有独特的自衍征。给出了 Cloeon/fg1（或 Kluge 2016 年的 Cloeonini 部落）、Procloeon/g1（或 Kluge 2016 年的 Procloeon 属）和 Securiops 的诊断。首次描述了南非物种 Procloeon（Securiops）falcatum（Crass 1947）的幼虫。根据来自赞比亚的饲养标本，重新描述了 Procloeon（Securiops）macafiertiorum Lugo-Ortiz（in Lugo-Ortiz & McCafferty）1996 的幼虫；该物种的亚成虫、成虫和卵均为首次描述。根据冈比亚的一个幼虫，报道了 Procloeon（Securiops）mutadens（Jacobus et al. 2006）组合的新幼虫特征。n.。根据来自泰国的饲养标本，重新描述了 Procloeon（Securiops）primasia（Kaltenbach 等人，2023）组合的幼虫。n.；该物种的亚成虫、成虫和发育良好的卵均为首次描述。首次为 Cheleocloeon excisum（Barnard 1932）的生殖器拍照。
