Abstract

Here, based on phylogenetic analyses of 18 taxa and 57 morphological characters, we propose a new firefly genus, Costalampys gen. nov., to accommodate eleven species. Five new species are herein described: C. bella sp. nov., C. capixaba sp. nov., C delicata sp. nov. (designated as type species), C. joanae sp. nov. and C. minima sp. nov. In addition, six species are redescribed and transferred from other genera: C. bisbinotata (Pic) comb. nov., transferred from Platylampis Motschulsky; C. decorata (Olivier) comb. nov., transferred from Ethra Laporte; C. pauper (Olivier) comb. nov., transferred from Cladodes Solier; as well as C. klugii (Motschulsky) comb. nov., C. quadriguttata (Gorham) comb. nov., and C. tricolor (Gorham) comb. nov., transferred from Lucidota Laporte. Costalampys gen. nov. is tentatively placed in Lampyrinae, and is diagnosed by: antennae with 11 articles, III–X basally flabellate, lacking dense and upright bristles; clypeus connected to frons by membrane, pygidium rounded; sternum VIII mucronate; phallus with dorsal plate enlarged apically, projecting ventrally and partially embracing the internal sac. Our phylogenetic analyses supported both the monophyly of Costalampys gen. nov. and the new combinations proposed. However, the relationship among congeneric species was poorly resolved. Finally, we provide illustrations of diagnostic features, distribution maps, as well as a key to Costalampys gen. nov. species, based on males.

大西洋雨林一新萤火虫属及其五新种和新组合的描述和系统发育分析（鞘翅目：Lampyridae：Lampyrinae）

基于对18个分类群和57个形态特征的系统发育分析，我们提出了一个新的萤火虫属，Costalampys gen.nov.，可容纳11个物种。本文报道了五个新种：C.bella sp.nov.、C.capixaba sp.nov..、C.delicata sp.nv..（指定为模式种）、C.joanae sp.novi.和C.minima sp.novl.此外，还重新描述并从其他属转移了六个物种：C.bisbinotata（图）comb。nov.，转自Platylampis Motschulsky；C.装饰梳。11月，转自Ethra Laporte；C.穷光蛋。nov.，转自Cladodes Solier；以及C.klugii（Motschulsky）comb。nov.，C.quadriguttata（Gorham）comb。nov.和C.tricolor（Gorham）comb。11月，从卢西多塔·拉波特转来。Costalampys gen.nov.暂定于Lampyrinae目，诊断为：触角有11条，III–X基部扇形，缺乏致密直立的刚毛；通过膜连接到叶上的灌肠器，扁基部圆形；胸骨VIII短尖；阴茎背板顶部增大，腹面突出，部分包围内囊。我们的系统发育分析支持Costalampys gen.nov.的单系性和提出的新组合。然而，同类物种之间的关系却没有得到很好的解决。最后，我们提供了基于雄性的诊断特征、分布图以及Costalampys gen.nov.物种的关键。
