“…The last antennal cleaner character differentiates the Psydrini from Moriomorphini (Baehr 1998;Liebherr 2020), as Psydrini exhibit a shorter, less well-developed antennal cleaner (Grade B of Hlavac 1971) versus that observed in Moriomorphini. The morphological results conform to phylogenetic hypotheses based on molecular sequence data (Maddison et al 1999(Maddison et al , 2019.…”

Tropopterus Solier, 1849, precinctive to southern South America, is taxonomically revised. Six new species are described: T. peckorumsp. nov., T. robustussp. nov., T. canaliculussp. nov., T. trisinuatussp. nov., T. minimucrosp. nov., and T. fieldianussp. nov.Merizodus catapileanus Jeannel, 1962, is synonymized with T. montagnei Solier, 1849. Lectotypes are designated for T. montagnei, T. giraudyi Solier, T. duponchelii Solier, and T. nitidus Solier (= T. duponchelii). Tropopterus peruvianus Straneo is noted as a nomen dubium, with its identity and taxonomic placement to be substantiated via neotype designation. Phylogenetic relationships among Tropopterus spp. are hypothesized based on 37 morphological characters, the distributions of which are analyzed under the parsimony criterion, with the cladogram root established between Tropopterus and its adelphotaxon from New South Wales, Australia. Speciation in the group has occurred predominantly at a limited geographical scale relative to the overall generic distribution, with three pairs of sister species sympatric. However phylogenetic divergence between taxa in the more northern, sclerophyllous forest characterized by Nothofagus obliqua (Brisseau de Mirbel) and those occupying the Valdivian and North Patagonian Rain Forest dominated by N. dombeyi (Brisseau de Mirbel) is observed in two instances of phylogenetic history. Using specific collecting locality records, it is shown that Tropopterus beetles have been collected syntopically and synchronically with species of Glypholoma Jeannel (Coleoptera, Staphylinidae), Anaballetus Newton, Švec & Fikáček (Coleoptera, Leiodidae), Andotypus Spangler (Coleoptera, Hydrophilidae), and Novonothrus Balogh (Acari, Oribatida). These concordant ecological occurrences document a cohesive Nothofagus forest leaf-litter community. These genera plus other Valdivian Rain Forest invertebrate taxa all exhibit an Austral disjunct biogeographical pattern that corroborates trans-Antarctic vicariance between the Nothofagus forests of southern South America and Australia. Male genitalic antisymmetry is shown to be a synapomorphy of Tropopterus, though the female reproductive tract retains the plesiomorphic orientation observed in all other moriomorphine taxa.

“…In contrast to the aquatic groups, published analyses of molecular datasets suffer from limited taxon sampling (e.g. Ober, 2002;Ribera et al, 2005;Ober & Maddison, 2008;Maddison et al, 2009Maddison et al, , 2019Gough et al, 2019), and consequently different phylogenetic issues remain unclarified, such as the placement of the enigmatic monospecific Cicindini (Stork, 1982;Erwin & Aschero, 2004) and Nototylini (Deuve, 1994). Autapomorphies of the family are the characteristic fine pubescence on antennomeres four to 11 of adults (or three to 11 in Harpalini) (char.…”

The evolution of the coleopteran suborder Adephaga is discussed based on a robust phylogenetic background. Analyses of morphological characters yield results nearly identical to recent molecular phylogenies, with the highly specialized Gyrinidae placed as sister to the remaining families, which form two large, reciprocally monophyletic subunits, the aquatic Haliplidae + Dytiscoidea (Meruidae, Noteridae, Aspidytidae, Amphizoidae, Hygrobiidae, Dytiscidae) on one hand, and the terrestrial Geadephaga (Trachypachidae + Carabidae) on the other. The ancestral habitat of Adephaga, either terrestrial or aquatic, remains ambiguous. The former option would imply two or three independent invasions of aquatic habitats, with very different structural adaptations in larvae of Gyrinidae, Haliplidae and Dytiscoidea.

“…The subfamily Trechinae is one clade in which patterns of sperm evolution appear evident, in part as there is a well-supported phylogenetic tree on which to examine our results (Maddison et al, 2019). Trechinae males vary in sperm conjugation presence and type (Figs.…”

“…The tree’s shape is predominately derived from large-scale molecular studies of ground beetle phylogeny (Maddison etal., 1999; 2009; Ober, 2002; Ober and Maddison, 2008). Additional molecular phylogenetic studies provided support for relationships in the following clades: Carabinae (Osawa et al, 2004), Cicindelinae (Vogler and Pearson, 1996; Gough et al, 2018), Harpalini (Martinez-Navarro et al, 2005), Paussinae (Moore, 2008; Robertson and Moore, 2016), Pterostichini and allies (Will and Gill, 2008), and Trechinae (Maddison and Ober, 2011; Maddison et al, 2019).…”

The beetle family Carabidae, with about 40,000 species, exhibits enough diversity in sperm structure and behavior to be an excellent model system for studying patterns and processes of sperm evolution. We explore their potential, documenting sperm form in 177 species of ground beetles and collecting data on 1 qualitative and 7 quantitative sperm phenotypic traits. Our sampling captures 61% of the tribal-level diversity of ground beetles. These data highlight the notable morphological diversity of sperm in ground beetles and suggest that sperm in the group have dynamic evolutionary histories with much morphological innovation and convergence. Sperm vary among species in total length from 48-3,400μm and in length and width of the sperm head. Most ground beetles make filamentous sperm with visually indistinct heads, but some or all studied members of the genus Omophron, genus Trachypachus, and tribe Dyschiriini make broad-headed sperm that show morphological differences between species. Most ground beetles package their sperm into groups of sperm, termed conjugates, and ground beetles show variation in conjugate form and in the number and arrangement of sperm in a conjugate. Most ground beetles make sperm conjugates by embedding their sperm in a non-cellular rod or spermatostyle, but some Trechitae make conjugates without a spermatostyle. The spermatostyle is remarkably variable among species and varies in length from 17-41,000μm. Several unrelated groups of ground beetles make only singleton sperm, including Nebriinae, Cicindelinae, many Trechinae, and the tribe Paussini. Given current views about ground beetle relationships, we propose preliminary hypotheses on ground beetle sperm diversification. We hypothesize that spermatostyle and conjugate traits evolve faster than sperm traits and that head width evolves more slowly than head length and sperm length. We propose that conjugation with a spermatostyle evolved early within the history of Carabidae and that it has been lost independently at least three times. Research highlights Ground beetle sperm is morphologically diverse. Most species make sperm conjugates with a spermatostyle, and there is variation in sperm, spermatostyles, and conjugates. Sperm have dynamic evolutionary histories.
