“…Our matrix included characters from male specimens, spanning the three tagmas: head (12), thorax (15), and abdomen (49). Of note, aedeagal traits yielded 20 characters.…”

“…Haplocauda gen. nov. can be distinguished from Costalampys by the pronotal posterior angle without an acute projection (Figure 5A), in addition to the elongated pygidium and sternum VIII (each nearly 1/3 longer than wide), with the sternum VIII having a long and wide posterior projection (Figure 6A-F). In Costalampys, the pronotal posterior angle has a minute acute projection, the pygidium is as long as wide, and sternum VIII is 2× wider than long and is mucronate or mildly sinuate (and lacking a long and wide posterior projection) [15]. Haplocauda gen. nov. can be distinguished from Scissicauda by the pygidium with sides convergent posteriorly from midlength, and the sternum VIII with a long and wide posterior projection (Figure 6A-F).…”

“…The study of lampyrid diversity has been hampered by a lack of taxonomic revisionary work and diagnostic resources to facilitate species identification, particularly in the Neotropics, where the family is most diverse. Despite recent advances in the Lampyrid classification remains unstable despite recent advances (e.g., [3]), and relationships among genera, as well as their monophyly, remain largely unexplored outside Luciolinae [4] (but see [10,11,15]). In order to determine the placement of these new species in Lampyridae, we included in our taxon sampling representatives of the four subfamilies that are known to occur in South America, namely, Psilocladinae (Psilocladus miltoderus Blanchard, 1846), Amydetinae (Amydetes fastigiata Illiger, 1807), and Lampyrinae, in addition to the taxa incertae sedis (Araucariocladus hiems Silveira & Mermudes, 2017, and Vesta thoracica Olivier, 1790).…”

“…Using MESQUITE [16], we built a matrix with 20 taxa scored for 76 characters following the guidelines of [17]. The data include 55 characters reanalyzed from [15] combined with 21 new characters (see Section 3; Supplemental Material S2). Measurement-based characters are taken at the longest or the widest point of the respective structure.…”

Most firefly genera have poorly defined taxonomic boundaries, especially in the Neotropics, where they are more diverse and more difficult to identify. Recent advances that shed light on the diversity of fireflies in South America have focused mainly on Atlantic Rainforest taxa, whereas lampyrids in other biomes remained largely unstudied. We found three new firefly species endemic to the Amazon basin that share unique traits of the male abdomen where sternum VIII and the pygidium are modified and likely work as a copulation clamp. Here we test and confirm the hypothesis that these three species form a monophyletic lineage and propose Haplocauda gen. nov. to accommodate the three new species. Both maximum parsimony and probabilistic (Bayesian and maximum likelihood) phylogenetic analyses confirmed Haplocauda gen. nov. monophyly, and consistently recovered it as the sister group to Scissicauda, fireflies endemic to the Atlantic Rainforest that also feature a copulation clamp on abdominal segment VIII, although with a different configuration. We provide illustrations, diagnostic descriptions, and keys to species based on males and females. The three new species were sampled from different regions, and are likely allopatric, a common pattern among Amazonian taxa.

“…In fact, South America is home to several endemic genera of fireflies across its biomes. For example, recent systematic efforts shed light on several lineages of fireflies endemic to the Atlantic Rainforest [ 3 , 4 , 5 , 6 , 7 , 8 ], a rather common trend in soft-bodied beetle families [ 9 , 10 , 11 , 12 ]. Likewise, endemic genera were recently identified in the Amazon Rainforest [ 13 ] and in the Chilean matorral ( Cladodes s.s. sensu [ 8 ]).…”

South America is likely the cradle of several New World firefly lineages but remains largely understudied. Despite several advances in firefly systematics in the Neotropical region, the Andean region has been largely unstudied for over a century. The Colombian Páramos are a critically threatened biodiversity hotspot that houses several endemic species, including the firefly genus Pseudolychnuris, with two species—P. vittata and P. suturalis. Here, by analyzing the phylogenetic relationships of Pseudolychnuris, we found that this genus is polyphyletic. Pseudolychnuris vittata and P. suturalis were found to be distantly related despite the striking similarity in outline and color pattern of males and females. We redescribe Pseudolychnuris and its type species P. vittata. Moreover, we revalidate Alychnus Kirsch, 1865 stat. rev. to accommodate A. suturalis comb. nov., also redescribed here. We provide updated distribution maps and report field observations for both monotypic genera. Since adults visit flowers and interact with pollen and nectar, Pseudolychnuris and Alychnus may be occasional pollinators of Andean-endemic plants, a phenomenon previously neglected. Our findings reveal an interesting case of convergence between Pseudolychnuris and Alychnus—probably associated with life in the Páramos—and shed light on character evolution in the Photinini lineage of fireflies.
