]]> RESUMO: The Lampyrinae tribe Cratomorphini includes some of the largest and most widespread New World fireflies. Their overlapping genus-level diagnoses are based on a few traits related to sexual signaling known to be fast-evolving and labile withingenus in other Lampyrinae taxa. To clarify the taxonomy and investigate the morphological evolution in Cratomorphini, Lamprocerini, and closely related taxa, we inferred the phylogenetic relationships of 50 species using 97 adult morphological characters contrasting the results of Maximum Parsimony Analysis and Bayesian Inference. Using a statistical framework, we demonstrate that terminalia and genitalic traits are less homoplastic than signaling or other somatic traits. Cratomorphini was recovered as polyphyletic, with four distinct clades, as follows: (i) Cratomorphus (partim: the type species, C. splendidus, and associated species) + Erythrolychnia bipartita; (ii) Cratomorphus (partim; transferred here to Nyctocera gen. nov. [Lamprocerini]); (iii) Cratomorphus (partim; transferred here to Bituca gen. nov. [Lampyrinae incertae sedis]) and (iv) (Micronaspis ((Aspisomoides, Pyractomena) Aspisoma)). Based on these results, we redefine Cratomorphini and Lamprocerini and present updated diagnoses for both tribes. We propose a new tribe, Aspisomini trib. nov. and establish two new genera: Nyctocera gen. nov. (within Lamprocerini sensu nov.) and Bituca gen. nov. (incertae sedis). Four species formerly assigned to Cratomorphus sensu nov. are transferred – three to Nyctocera gen. nov., and one to Bituca gen. nov. – and all are redescribed based on type and additional material. We illustrate all diagnostic features, and provide updated keys to the genera of Cratomorphini sensu nov., Aspisomini trib. nov., and Lamprocerini sensu nov. Additionally, we identify and discuss synapomorphies for clades previously recovered only in DNA-based phylogenies. Our work stresses the need for thorough investigations of morphological data, especially of the terminalia and genitalia, to elucidate the phylogeny of fireflies.

]]> RESUMO: Lucidotini Lacordaire 1857 is a highly diverse and remarkably widespread lineage of fireflies, with approximately 850 species distributed across 34 recognized genera and 4 currently accepted subtribes: Dadophorina Olivier 1907, Lucidotina Lacordaire 1857, Phosphaenina McDermott 1964, and Photinina LeConte 1881. The taxonomy of Lucidotini has long been hindered and complicated by outdated or imprecise diagnoses, and their phylogenetic affinities remain poorly understood. Traditionally, Phosphaenina includes the genera Phosphaenus Laporte 1833 and Phosphaenopterus Schaufuss 1870, but recent phylogenetic analyses have suggested close affinities to other lineages, which challenged the monophyly of Lucidotini subtribes. In the present study, we reassess the composition, limits, and defining characters of Phosphaenina based on a phylogenetic analysis of 30 taxa and 94 morphological characters under Maximum Parsimony and Bayesian Inference. Our results support a comprehensive redefinition of Phosphaenina s.n. to include: Dinophallus gen. n., Dociluta gen. n., Lucidina Gorham 1883, Luciuranus Silveira et al. 2016, Phosphaenopterus, Phosphaenus, and Streptophallus gen. n., and Lucidota partim (Lucidota atra [Olivier 1790], Lucidota punctata [LeConte 1852], and Dociluta pygmea comb. n.). We also describe 3 new genera and 4 new species and provide new diagnostic traits and an updated key to the genera of Phosphaenina s.n. Among the traits supporting Phosphaenina s.n. is a joint anchoring the phallic dorsal plate to the parameres, described herein. These findings underscore the value of comprehensive morphological studies in clarifying the taxonomy and evolutionary relationships within Lucidotini.
