“…High diversity and a long time increase the probability of the independent origin of similar structures as seen in the repeated origin of the shortened primary costa 1 in the hyperdiverse Metriorrhynchini (Leptotrichalus Kleine versus the genera of the trichaline clade; Sklenarova et al 2014;Bocek & Bocak 2017;Motyka et al 2021). Analogically, costa 3 can be shortened in some stenopterous lycids (Kazantsev 2020;Kusy et al 2022). The costae of net-winged beetles are more apparent than in related elateroid families and very probably evolved as a strengthening structure in a soft-bodied group from rows of cells in wellsclerotized relatives, such as Artematopodidae, some Eucnemidae, and Elateridae (McKenna et al 2019).…”

We simultaneously considered morphology and molecular phylogeny to modify the generic classification of the ‘pyropterine clade’ (Lycidae, Erotinae, Dictyopterini). To place species previously included in Benibotarus Kôno, 1932 in reciprocally monophyletic genera, we propose Gomezzuritus gen. nov. with the type-species Dictyopterus alternatus Fairmaire, 1856. Further, we transfer Gomezzuritus alternatus (Fairmaire, 1856) comb. nov., G. longicornis (Reiche, 1878) comb. nov., and G. rubripes (Pic, 1897) comb. nov. from Benibotarus to Gomezzuritus gen. nov. The pyropterine clade contains five genera in the Palaearctic region: Pyropterus Mulsant, 1838, Gomezzuritus gen. nov., Helcophorus Fairmaire, 1891, Greenarus Kazantsev, 1995, and Benibotarus Kôno, 1932. The arrangement of longitudinal elytral costae proved misleading for consideration of relationships. Two genera in distant positions share only four primary costae (Pyropterus and Helcophorus), and three similarly distant genera share the shortened primary costa 3, resulting in three primary and four secondary longitudinal costae (Gomezzuritus, Greenarus, and Benibotarus). The larva of Gomezzuritus alternatus is described in detail, and it is compared with the larvae of other Dictyopterini, including the presumed larva of G. longicornis.

“…The pyropterine clade is distributed in the Palaearctic, Nearctic, and Oriental (northern part only, i.e., northern Thailand and Laos) realms (Masek et al 2018;Kazantsev, 2020). Fossil taxa of these groups have been recorded from Baltic and Rovno amber (Kazantsev & Perkovsky 2022).…”

“…The described Lycidae fossil record encompasses both impressions and amber inclusions. Of these, a total of 11 species have been described from amber from various deposits, including Cretaceous Burmese amber (two species), Eocene Baltic amber (five species), Miocene Dominican amber (three species) and from Miocene Mexican amber (one species); detailed lists of amber Lycidae may be found in Kazantsev (2020), Li et al (2021), and. The recent posting of photographs of a Dominican amber Lycidae specimen on Facebook groups by Enrico Bonino was brought to VSF's attention by Fabrizio Fanti.…”

Paedomorphosis is a heterochronic syndrome in which adult individuals display features of their immature forms. In beetles, this phenomenon occurs widely in the superfamily Elateroidea, including the net-winged beetles (Lycidae), and, due to the usual flightlessness of paedomorphic females, it is hypothesized to cause speciation rates higher than in non-paedomorphic lineages. However, some fossils of paedomorphic lycids do not support this with palaeobiological data. Discovery of new Lycidae fossils attributed to the West Indian extant paedomorphic genus Cessator Kazantsev in the Dominican amber also suggests morphological stasis within this genus in the Greater Antilles. We describe Cessator anachronicus Ferreira and Ivie, sp. nov. based on adult males, as well as the first ever recorded fossil net-winged beetle larva of the same genus. We propose that the relatively young age of the studied fossils combined with the stable conditions in the forest floor of the Greater Antilles through the last tens of million years could explain the exceptionally conserved morphology in the net-winged beetles affected by the paedomorphic syndrome.
