Shear, W. A. 1975 . The opilionid family Caddidae in North America, with notes on species from othe r regions (Opiliones, Palpatores, Caddoidea) . J. Arachnol . 2:65-88 . THE OPILIONID FAMILY CADDIDAE IN NORTH AMERICA, WITH NOTES ON SPECIES FROM OTHER REGION S (OPILIONES, PALPATORES, CADDOIDEA ) William A . Shear Biology Departmen t Hampden-Sydney, College Hampden-Sydney, Virginia 23943 ABSTRACT Species belonging to the opilionid genera Caddo, Acropsopilio, Austropsopilio and Cadella are herein considered to constitute the family Caddidae . The subfamily Caddinae contains the genu s Caddo ; the other genera are placed in the subfamily Acropsopilioninae. It is suggested that the palpatorid Opiliones be grouped in three superfamilies : Caddoidea (including the family Caddidae) , Phalangioidea (including the families Phalangiidae, Liobunidae, Neopilionidae and Sclerosomatidae ) and Troguloidea (including the families Trogulidae, Nemostomatidae, Ischyropsalidae an d Sabaconidae). North American members of the Caddidae are discussed in detail, and a new species , Caddo pepperella, is described . The North American caddids appear to be mostly parthenogenetic, an d C. pepperella is very likely a neotenic isolate of C. agilis. Illustrations and taxonomic notes ar e provided for the majority of the exotic species of the family . INTRODUCTION Considerable confusion has surrounded the taxonomy of the order Opiliones in North America, since the early work of the prolific Nathan Banks, who described many of ou r species in the last decade of the 1800's and the first few years of this century. For many species, no additional descriptive material has been published following the original de- scriptions, most of which were brief and concentrated on such characters as color and body proportions . -

Anatomically Modern Carboniferous Harvestmen Demonstrate Early Cladogenesis and Stasis in Opiliones
ARTICLE Received 14 Feb 2011 | Accepted 27 Jul 2011 | Published 23 Aug 2011 DOI: 10.1038/ncomms1458 Anatomically modern Carboniferous harvestmen demonstrate early cladogenesis and stasis in Opiliones Russell J. Garwood1, Jason A. Dunlop2, Gonzalo Giribet3 & Mark D. Sutton1 Harvestmen, the third most-diverse arachnid order, are an ancient group found on all continental landmasses, except Antarctica. However, a terrestrial mode of life and leathery, poorly mineralized exoskeleton makes preservation unlikely, and their fossil record is limited. The few Palaeozoic species discovered to date appear surprisingly modern, but are too poorly preserved to allow unequivocal taxonomic placement. Here, we use high-resolution X-ray micro-tomography to describe two new harvestmen from the Carboniferous (~305 Myr) of France. The resulting computer models allow the first phylogenetic analysis of any Palaeozoic Opiliones, explicitly resolving both specimens as members of different extant lineages, and providing corroboration for molecular estimates of an early Palaeozoic radiation within the order. Furthermore, remarkable similarities between these fossils and extant harvestmen implies extensive morphological stasis in the order. Compared with other arachnids—and terrestrial arthropods generally—harvestmen are amongst the first groups to evolve fully modern body plans. 1 Department of Earth Science and Engineering, Imperial College, London SW7 2AZ, UK. 2 Museum für Naturkunde at the Humboldt University Berlin, D-10115 Berlin, Germany. 3 Department of Organismic and Evolutionary Biology and Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts 02138, USA.

SP., A REMARKABLE NEW HARVESTMAN FROM A CAVE IN WEST VIRGINIA, WITH COMMENTS ON OTHER REPORTED CAVE-DWELLING HESPERONEMASTOMA SPECIES (OPILIONES, ISCHYROPSALIDOIDEA, SABACONIDAE) WILLIAM A. SHEAR Biology Department, Hampden-Sydney College, Hampden-Sydney, VA 23943, [email protected] Abstract: Hesperonemastoma smilax, n. sp., is a minute, highly troglomorphic harvestman described herein from a single male specimen collected in McClung’s Cave, Greenbrier County, West Virginia. Hesperonemastoma species described previously from caves are briefly discussed. H. packardi (Roewer), first collected in a shallow cave in Utah, is a widely distributed surface-dwelling species found mostly in riparian canyon habitats in northern Utah; it shows no troglomorphic adaptations. Hesperonemastoma inops (Packard), described from a cave in Kentucky, is not a species of Hesperonemastoma, but most likely a juvenile of Sabacon cavicolens (Packard), which was described from the same small cave. Hesperonemastoma pallidimaculosum (Goodnight and Goodnight) is a moderately adapted troglobiont known from two caves in Alabama.

Štúra 2, 960 53 Zvolen, Slovakia; e-mails: [email protected], [email protected], [email protected] Key words. Opiliones, harvestmen, assemblages, biodiversity, canopy cover, European beech forests Abstract. We studied the effects of the overstory canopy cover on ground-dwelling harvestmen communities in European beech forests in the Western Carpathian Mts. We analyzed the differences in species richness, abundance and composition in two tree canopy cover categories (closed and open canopy). Overall, 1765 individuals belonging to 16 species were caught using pitfall traps. Repeated-measures ANOVA revealed that under both closed and open canopies a similar absolute and rarefi ed species richness and number of individuals (standardized to 100 pitfall trap days) were caught, and that both species richness and abun- dance were affected by the season (i.e., time of trap replacement); yet the total number of individuals trapped was more than two times greater under the open canopy than under the closed canopy. Despite the subtle differences in the taxonomic composi- tion of the catches under the open and closed canopies revealed by DCA followed by RDA, the composition of ground-dwelling harvestmen assemblages differed under the two canopy covers. The open canopy was more suitable for heliophilic, xerothermic eurytopic harvestmen species typical for open and ecotonal habitats, such as Egaenus convexus (C.L. -
Invertebrates of Slapton Ley National Nature Reserve (Fsc) and Prawle Point (National Trust)
CLARK & BECCALONI (2018). FIELD STUDIES (http://fsj.field-studies-council.org/) INVERTEBRATES OF SLAPTON LEY NATIONAL NATURE RESERVE (FSC) AND PRAWLE POINT (NATIONAL TRUST) RACHEL J. CLARK AND JANET BECCALONI Department of Life Sciences, Natural History Museum, Cromwell Road, London SW7 5BD. In 2014 the Natural History Museum, London organised a field trip to Slapton. These field notes report on the trip, giving details of methodology, the species collected and those of notable status. INTRODUCTION OBjectives A field trip to Slapton was organised, funded and undertaken by the Natural History Museum, London (NHM) in July 2014. The main objective was to acquire tissues of UK invertebrates for the Molecular Collections Facility (MCF) at the NHM. The other objectives were to: 1. Acquire specimens of hitherto under-represented species in the NHM collection; 2. Provide UK invertebrate records for the Field Studies Council (FSC), local wildlife trusts, Natural England, the National Trust and the National Biodiversity Network (NBN) Gateway; 3. Develop a partnership between these organisations and the NHM; 4. Publish records of new/under-recorded species for the area in Field Studies (the publication of the FSC). Background to the NHM collections The NHM is home to over 80 million specimens and objects. The Museum uses best practice in curating and preserving specimens for perpetuity. In 2012 the Molecular Collections Facilities (MCF) was opened at the NHM. The MCF houses a variety of material including botanical, entomological and zoological tissues in state-of-the-art freezers ranging in temperature from -20ºC and -80ºC to -150ºC (Figs. 1). As well as tissues, a genomic DNA collection is also being developed. -

Milne4, Nicholas S. Gladstone5, Annette S. Engel6, John B. Jensen7, Carlos D. Camp8, James C. Ozier9, and Alan Cressler10 Abstract We provide an annotated checklist of species recorded from caves and other subterranean habitats in the state of Georgia, USA. We report 281 species (228 invertebrates and 53 vertebrates), including 51 troglobionts (cave-obligate species), from more than 150 sites (caves, springs, and wells). Endemism is high; of the troglobionts, 17 (33 % of those known from the state) are endemic to Georgia and seven (14 %) are known from a single cave. We identified three biogeographic clusters of troglobionts. Two clusters are located in the northwestern part of the state, west of Lookout Mountain in Lookout Valley and east of Lookout Mountain in the Valley and Ridge. In addition, there is a group of tro- globionts found only in the southwestern corner of the state and associated with the Upper Floridan Aquifer. At least two dozen potentially undescribed species have been collected from caves; clarifying the taxonomic status of these organisms would improve our understanding of cave biodiversity in the state. -

Shear: Department of Biology, Hampden-Sydney College, Hampden- Sydney, Virginia 23943 U.S.A. ABSTRACT. The tiny caddid harvestman Acropsopilio chomulae (Goodnight & Goodnight 1948), from Chiapas, Mexico, has been known only from the immature holotype. Mature females are described from specimens taken near the type locality. The absence of spermathecae in the ovipositor makes it likely that the species is parthenogenic. RESUMEN.
