“…The family Phengodidae LeConte, 1861 is composed of 304 species and 40 genera in the New World (from southern Canada to central Chile-Argentina) and in the Levant and Asia Minor (Costa & Zaragoza-Caballero 2010;Constantin 2014Constantin , 2016Zaragoza-Caballero & Pérez-Hernández 2014;Roza et al 2017Roza et al , 2018Kundrata et al 2019;Roza & Mermudes 2019Vega-Badillo & Zaragoza-Caballero 2019;Vega-Badillo et al 2020, 2021a, 2021b. Currently, Phengodidae has four subfamilies: Cydistinae Paulus, 1972, distributed in Levant, Asia Minor and Iran (Kundrata et al 2019), and Mastinocerinae LeConte, 1881, Penicillophorinae Paulus, 1974and Phengodinae LeConte, 1861, distributed in the Americas (Zaragoza-Caballero & Pérez-Hernández 2014).…”

Here I describe a new genus, Iviephengus gen. nov., based on a single species, Iviephengus ferreirai gen. et sp. nov., from Peru. This new genus is characterized by the following combination of characters: interantennal distance close to 3 × the antennal socket length; antenna 12-segmented, IV to XI each with two long symmetrical compressed and apically slightly enlarged branches; labrum fused to frontoclypeus; mandibles short, obliquely crossed, each with a notch on the external margin to fit the other mandible and without extra teeth; maxillary palpi 4-segmented, last segment digitiform; labial palpi 2-segmented; posterior tentorial pit consisting of a single small fossa; wing with radial cell closed and transverse, vein r4 interrupted, r3 absent; first tarsomere of pro- and mesotarsus with a ventral comb covering the posterior half of the tarsomere; claws simple, without any teeth; aedeagus with paramere symmetrical, apex unevenly round, toothed inward, with short and sparse bristles. I provide a key to Mastinocerinae genera with 12-segmented antennae and the first pro- and mesotarsomere with ventral combs. I also provide illustrations for the diagnostic features for this new genus. Finally, I discuss the presence and function of some modifications in the mandible and the sternite VIII in Phengodidae and other Coleopteran families.

Phengodidae (Coleoptera: Elateroidea), commonly known as glowworm beetles, are a small family of bioluminescent and paedomorphic beetles. There are few phylogenetic studies of Phengodidae, and these are mostly discordant, especially when comparing morphology-based and molecular-based phylogenetic hypotheses. Here, we used the anchored hybrid enrichment approach to undertake the first phylogenomic analysis of Phengodidae (≤358 loci and 39 taxa) and evaluate the higher-level classification of the group. In agreement with previous molecular studies, we recovered Phengodidae as sister to Rhagophthalmidae, and the Old World Cydistinae as sister to all New World Phengodidae. In contrast to previous hypotheses, both Phengodinae and Mastinocerinae were each recovered as monophyletic. Cenophengus was found to be sister to Mastinocerinae, in contrast to some previous hypotheses that placed it as sister to all New World Phengodidae. Considering its morphological divergence, we here establish Cenophenginae subfam. nov. Despite the largest and most comprehensive sampling of Phengodidae in any molecular-based study to date, we had only limited success in revealing the relationships among genera within the most species-rich subfamily, Mastinocerinae. Further studies should focus on the phylogeny and classification of this taxonomically neglected subfamily, on the phylogenetic placement of enigmatic Penicillophorinae, and on seeking morphological support for the main clades of Phengodidae.
