“…Finally, we will discuss whether the results of the phylogeographic analysis are consistent with the assumption of a Tibetan origin for the Ethira clade. In performing this work, we benefited greatly from the previous studies carried out by Sasakawa & Kubota [27] , [28] and of Will & Gill [29] , who studied several other Pterostichini ground beetle groups, thus providing a comprehensive set of DNA sequences for comparison.…”

Into the Himalayan Exile: The Phylogeography of the Ground Beetle Ethira clade Supports the Tibetan Origin of Forest-Dwelling Himalayan Species Groups

The Himalayan mountain arc is one of the hotspots of biodiversity on earth, and species diversity is expected to be especially high among insects in this region. Little is known about the origin of the Himalayan insect fauna. With respect to the fauna of high altitude cloud forests, it has generally been accepted that Himalayan lineages are derived from ancestors that immigrated from Western Asia and from adjacent mountainous regions of East and Southeast Asia (immigration hypothesis). In this study, we sought to test a Tibetan Origin as an alternative hypothesis for groups with a poor dispersal ability through a phylogeographic analysis of the Ethira clade of the genus Pterostichus. We sequenced COI mtDNA and the 18S and 28S rDNA genes in 168 Pterostichini specimens, including 46 species and subspecies of the Ethira clade. In our analysis, we were able to show that the Ethira clade is monophyletic and, thus, represents a Himalayan endemic clade, supporting endemism of two of the basal lineages to the Central Himalaya and documenting large distributional gaps within the phylogeographic structure of the Ethira clade. Furthermore, the molecular data strongly indicate very limited dispersal abilities of species and subspecies of these primary wingless ground beetles. These results are consistent with the hypothesis of a Tibetan Origin, which explains the evolution, diversity and distribution of the Himalayan ground beetle Ethira clade much more parsimoniously than the original immigration hypothesis.

“…Based on DNA analysis, a recent phylogeny supports Anilloferonia (comprised of P. lanei, P. malkini, and P. testacea) as a valid subgenus (Will and Gill 2008). This same paper concludes that P. rothi is actually a member of the subgenus Leptoferonia Casey, 1918.…”

Pterostichus (Anilloferonia) malkini (Hatch), 1953, was described from a single female collected in 1951. Since then five more specimens have been collected, including males. Based on this additional material it is clear this species is valid, which had been uncertain. Since the original description of P. malkini did not include male characteristics, several of which are diagnostic, a detailed description of this species is provided. Locality and habitat details for this rarely collected species are included. Characters differentiating P. malkini from the other species of P. (Anilloferonia) are illustrated and discussed.

“…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.
