(Annelida, Hirudinida: Erpobdellidae) <p>Two species of leeches were described from Georgia in the past, <em>Dina ratschaensis</em> Kobakhidze, 1958 from the Racha-Lechkhumi and Kvemo Svaneti region and <em>Trocheta ariescornuta</em> Grosser, Barjadze &amp; Maghradze, 2021 from the Samegrelo-Zemo Svaneti region. Both species were the only known typical representatives of cave leeches in Georgia. Recently, two more species of the genus <em>Dina</em> R. Blanchard, 1894 have been found in karst caves in this country. These leeches are morphologically similar to<em> D. ratschaensis</em>, from which they differ in the shape of the reproductive system, primarily the shape of the cornua of the genital atrium and the shape and extension of the vasa deferentia and ovisacs, justifying the description of two new species, <em>Dina imeretiensis</em> Grosser, Barjadze &amp; Maghradze sp. nov. from the Imereti region and <em>Dina samegreloensis</em> Grosser, Barjadze &amp; Shavadze sp. nov. from the Samegrelo-Zemo Svaneti region. Data on the cave dwelling invertebrate communities in the studied caves are provided. Molecular data are provided, and a phylogenetic tree based on Cox1 sequences of <em>Dina</em> spp. and related genera is provided and discussed.</p> Clemens Grosser, Shalva Barjadze, Eter Maghradze, Lado Shavadze, Vladimir Pešić, Arnaud Faille Copyright (c) 2023 Clemens Grosser, Shalva Barjadze, Eter Maghradze, Lado Shavadze, Vladimir Pešić, Arnaud Faille Wed, 20 Sep 2023 00:00:00 -0700 Description of a new species of Hobbsinella (Crustacea, Bathynellacea, Bathynellidae) from Colorado (USA) based on morphological and molecular characters <p>A new species of Bathynellidae is described from Colorado (USA). <em>Hobbsinella</em> <em>gunnisonensis</em> Camacho &amp; Taylor sp. nov. displays a unique combination of morphological characters including seven-segmented antenna lacking medial seta on exopod, antennule slightly longer than antenna, three-segmented mandibular palp, four articles on endopod of thoracopods I to VII and five spines on sympod and three spines on endopod of the uropods. Partial sequences of cytochrome oxidase I (COI) and 18S have been obtained from several specimens of the new species. The mitocondrial and nuclear DNA data complement the traditional morphological taxonomic description support the validity of the new species. Molecular data for the Bathynellidae demonstrate the presence of two highly divergent genetic units, with the new species placed in the genus<em> Hobbsinella</em>. With the description of <em>Hobbsinella gunnisonensis</em> Camacho &amp; Taylor sp. nov. and its molecular characterization, we discovered an interesting distribution of the genus, which occurs in both sides of the Continental Divide (Texas and Colorado) and different habitats.</p> Ana Isabel Camacho, Paloma Mas-Peinado, Carly B.

A total of 61&nbsp;taxa (59&nbsp;species and two varieties) of <em>Habenaria</em> are recorded for Chapada dos Veadeiros, representing a two-fold increase compared to previous lists and comprising one of the greatest diversities of the genus in Brazil. Of this total, four taxa are locally endemic. <em>Habenaria cultellifolia</em>, until recently known only from the type collection, was rediscovered in the region after 127&nbsp;years without records and represents this species’ only known extant population. Three proposed new taxa of <em>Habenaria</em> (<em>H. minuticalcar</em> J.A.N. Bat. &amp;#38; Bianch. sp. nov., <em>H. proiteana</em> J.A.N. Bat., A.A. Vale &amp;#38; Bianch. sp. nov., and <em>H. lavrensis</em> var. <em>xanthodactyla</em> J.A.N. Bat. &amp;#38; Bianch. var. nov.) are corroborated by molecular phylogenetic analyses based on nuclear and plastid markers. They are described, illustrated, tentatively assessed as threatened, and compared to phylogenetically and morphologically related species. Since some areas of this mountain range have not yet been floristically sampled, additional taxonomic novelties and new records are still expected in the future.</p> João A. N.

(male and female) from Costa Rica, <em>R. spock </em>gen. et sp. nov. (female) from Campeche, Mexico and <em>R. mccoy </em>gen. et sp. nov. (male) from Baja California Sur, Mexico, as well as two species previously misplaced in <em>Caponina </em>Simon, i.e., <em>R. sargi </em>(Pickard-Cambridge, 1899) gen. et comb. nov. from Guatemala and <em>R. pelegrina </em>(Bryant, 1940) gen. et comb. nov. from Cuba. A male specimen reported as <em>C. sargi </em>Pickard-Cambridge from Costa Rica by E. Kritscher (1957) is assigned to <em>Roddenberryus kirk </em>together with one female collected at the same locality. The new genus is characterized by the distally projected endites and a triangular, projected labium, a conformation unique among nopines; also by a triangular, very short, scaly gladius, serrula with interspersed multiple tooth rows, and a tarsal organ with strongly projected margins. <em>Roddenberryus </em>shares with <em>Tarsonops </em>Chamberlin the cracked tarsi and metatarsi, with multiple adesmatic joints intertwined on the cuticle and an unusual internal respiratory system with both posterior tracheae fused in a single trunk.</p> Alexander Sánchez-Ruiz, Alexandre B.

Calcetas Thu, 31 Aug 2023 00:25:10 -0700 Can biogeography help bumblebee conservation? <p>Bumblebees (<em>Bombus </em>Latreille, 1802), because of their large body size, bright colours and activity at times and places that coincide with biologists, are an example of a group of insects that is particularly well represented in museum collections. This is important if taxonomic revisions are to achieve greater comparability among species. Bumblebees have also attracted particular attention because they are especially ecologically and economically valuable for pollination in north temperate regions, where they are now becoming increasingly threatened. I argue that the what, the where, and the how of effective conservation management may be informed by understanding the divergent characteristics that have affected their biogeographical past: by helping us to see ‘the woods’, not just ‘the trees’, of their habitat needs. Identifying suitable habitat should be part of reconstructing historical biogeography within taxonomic revisions. For bumblebees, for example, biogeographical analysis associates major taxonomic groups either with flower-rich lowland grasslands or with flower-rich montane grasslands, highlighting their contrasting requirements for: nest sites, flowers of different depths, pollen-plant families, and especially the differing importance of early spring and late summer flowers for breeding success. This broad view of species groups helps filter the less important idiosyncrasies from local case studies in order to focus conservation actions.</p> Paul H.

Wed, 30 Aug 2023 01:20:46 -0700 A new species of Liolaemus (Iguania: Liolaemidae) from the hot deserts of northern Patagonia, Argentina <p>A new species of <em>Liolaemus</em> is described from southwest of the town of Añelo, Neuquén Province, Argentina. Integrative evidence methodology of external morphological characters and molecular phylogenetic analyses of mitochondrial DNA (cyt-<em>b</em>) is used to place the new species to the species group of <em>Liolaemus boulengeri</em>. The new species is phenotypically close to <em>L.&nbsp;mapuche</em>. The new <em>Liolaemus</em> is medium to large in size (males 77.64–83.98&nbsp;mm, females 72.88–78.58&nbsp;mm), with evident sexual dichromatism. Genetic distances of the mtDNA (cyt-<em>b</em>) between the new species and its closest relative species are greater than 3% (<em>L.&nbsp;cuyanus</em> 7.48–12.02%; <em>L.&nbsp;josei</em> 7.56–9.60%; <em>L.&nbsp;puelche</em> 8.23–9.93%; <em>L.&nbsp;mapuche</em> 8.51–9.79%). Molecular and morphological phylogenetic results show <em>L.&nbsp;mapuche</em> as the sister species of the new one. The new species is larger than <em>L.&nbsp;mapuche</em>. Dorsal and ventral scales are more numerous in the new species than in <em>L.&nbsp;mapuche</em>, precloacal pores in females are present in <em>L.&nbsp;mapuche</em> and absent in the new species. It has strict psammophilic habits, using sand mounds and sheltering, under Alpataco (<em>Neltuma alpataco</em>) bushes. The <em>L.&nbsp;boulengeri</em> group now contains 75&nbsp;species distributed in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru and Uruguay.</p> Cristian S. Abdala, Pablo Anselmo Chafrat, Juan C.
