“…The initial tribal placement of Lycinella was difficult because it is among the genera that, like Cephalolycus Pic, 1926 and Aporrhipis Pascoe, 1887, shares features of both Calopterini and Leptolycini (see Miller 1991; Bocáková 2003, 2005; Ferreira and Ivie 2016; Ferreira et al 2018). Bocák and Bocáková (1990) placed the genus in the Leptolycini, but based on examination of Lycinellahumeralis , here moved to the Leptolycine genus Ceratoprion .…”

“…Ferreira and Ivie (2016) and Ferreira et al (2018), discuss the morphological delimitation between males of Calopterini and Leptolycini, which is based on a weak tarsal character (Miller 1991, Ferreira and Ivie 2016), and placement of taxa such as Cephalolycus , Aporrhipis and Acroleptina (Ferreira and Ivie 2016, Kazantsev 2017) remains unclear. Although Lycinella has the narrow tarsomere IV normally present in Leptolycini, Lycinella lacks the reduced mouthparts found in all adult male Leptolycini.…”

“…These structures were first noted by Miller (1991), who was the first to use stemmata in this way. His usage has been subsequently followed by Ferreira and Ivie (2016) and Ferreira et al (2018). Pronotal stemmata are tiny hemispherical white objects that occur on the pronotum, coxae and antenna of adult males (Figs 11, 12).…”

“…These Costa Rican specimens have eight pronotal stemmata (Figure 11), an apparently unpublished character discovered by Richard S. Miller (1991) in Leptolycus Leng & Mutchler, 1922 (Leptolycini). However, they did not seem to belong to the Leptolycini, based on current diagnoses (Ferreira and Ivie 2016, Ferreira et al 2018). …”

The Neotropical genus Lycinella Gorham, 1884 is revised. Lycinellaopaca Gorham, 1884 and Lycinellaparvula Gorham, 1884 are redescribed and illustrated. Six new species are described for the genus: Lycinellaadamantissp. n., L.hansonisp. n., L.millerisp. n., L.cidaoisp. n., L.marshallisp. n. and L.pugliesaesp. n.. Lycinellahumeralis Pic, 1933 is moved to Ceratoprionhumerale (Pic, 1933), comb. n. A key to the species of Lycinella, illustrations and a distribution map is provided.

“…Despite the progress, much still remains unknown and some of the most diverse and abundant and specious groups of Lycidae in the Neotropical region, such as Calopteron Guérin-Méneville, 1830 (Lycinae, Calopterini) and Plateros Bourgeois, 1879 (Lycinae, Platerodini), to mention two very emblematic cases, are almost impossible to be identified at species level. The majority of recent taxonomic works in Neotropical Lycidae focus in relatively small and less diverse genera of Lycidae (e.g., Nascimento & Bocakova, 2009;Ferreira & Ivie, 2016).…”

Lycidae are among the better studied groups in the superfamily Elateroidea, however despite the progress in the taxonomic understanding of the Neotropical fauna, much still remains unknown and undescribed in the region. The description of the new genus Xenolycus gen. nov., from Serra dos Órgãos, a subrange of the Serra do Mar mountain range, in the Atlantic Rainforest in Rio de Janeiro State, Brazil, contributes to the knowledge of the Neotropical Lycidae fauna. The new genus can be distinguished from all other known Calopterini and Neotropical Lycidae by the combination of a pronotum with a wide, deep and strongly visible longitudinal cell in the disc area, the filiform antennae, the dehiscent elytra with reticulation strongly reduced and bearing only two weakly developed elytral costae and the mouthparts partially reduced, with rudimentary, barely visible mandibles. The type species, Xenolycus costae sp. nov., is illustrated and diagnostic characters and a discussion on the tribal placement of the new genus are provided.

Dominican amber net-winged beetles suggest stable paleoenvironment as a driver for conserved morphology in a paedomorphic lineage

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.
