Hypogean pseudoscorpions (Arachnida) from Jaén province (Andalusia, Spain), with descriptions of four new species and a new synonymy.

Four new hypogean species are described from the Jaén province (southern Spain): Chthonius (Ephippiochthonius) espa- nyoli sp. nov., C. (E.) giennensis sp. nov., C. (E.) villacarrillo sp. nov. and Neobisium (Ommatoblothrus) perezruizi sp. nov. New records are given for the species Chthonius (E.) cazorlensis, C. (E.) perezi, C. (E.) tetrachelatus, Neobisium (O.) perezi, Microcreagrella caeca caeca and Allochernes masi. Chthonius (E.) verai and C. (E.) minutus are removed from the list of the Andalusian fauna. A new synonymy is proposed: Neobisium (O.) gev Carabajal Márquez, García Carrillo & Rodríguez Fernández, 2011, is a junior subjective synonym of N. (O.) perezi Carabajal Márquez, García Carrillo & Rodríguez Fernández, 2011.

On hypogean Roncocreagris (Arachnida: Pseudoscorpiones: Neobisiidae) from Portugal, with descriptions of three new species.

Three new hypogean species of the Iberian genus Roncocreagris Mahnert, 1974 are described from mainland Portugal: R. borgesi sp. nov. and R. gepesi sp. nov. from caves in the Sicó massif, and R. occidentalis sp. nov. from caves in the Montejunto and Cesaredas karst plateau. This brings to nine the number of known hypogean species of the mostly Iberian genus Roncocreagris: five from Portugal and four from Spain. Ecological comments and new localities for some of the previously known species are also included.

A new pseudoscorpion genus from western Georgia (Pseudoscorpiones: Neobisiidae: Cornuroncus n. gen.), with a key to all Neobisiinae genera.

A new genus and species of epigean pseudoscorpions belonging to the subfamily Neobisiinae Chamberlin, 1930, is described from western Georgia and its diagnostic characters are illustrated. Cornuroncus n. gen. resembles the genus Roncus L. Koch, 1873 in several characters but differs by having a short dorso-distal spine on tarsus IV, and the presence of a ventral tooth on one of the claws of tarsus IV. An identification key for all valid Neobisiinae genera is provided.

A daily multidisciplinary assessment of older adults undergoing elective colorectal cancer surgery is associated with reduced delirium and geriatric syndromes.

OBJECTIVES: Comprehensive geriatric assessment (CGA) has shown to benefit older patients undergoing urological and orthopedic surgery. However, this approach has been scarcely assessed in patients elected for colorectal surgery. MATERIALS AND METHODS: Retrospective cohort of patients aged ≥70 years admitted for elective colorectal cancer surgery to a single hospital between 2008 and 2012. Upon admission, patients were assigned to a usual care (UC) plan or a CGA-based care (GS) plan conducted by a multidisciplinary team, according to standard clinical criteria.Analyzed outcomes included the incidence of delirium and other geriatric syndromes during hospital stay, mortality, readmissions, andnumber of perioperative complications. RESULTS: The cohort included 310 patients, 203 assigned to the GS group and 107 to the UC group. Patients in the GS group had significantly lower Barthel and Lawton scores, higher prevalence of dementia and heart failure, and higher comorbidity burden. Fifty-four (17.5%) patientsexperienced delirium (23 [11.3%] and 31 [29.2%] in the GS and UC groups, respectively; p < .001), and 49 (15.8%) patient experienced other geriatric syndromes (21 [10.3%] and 28 [26.2%] in the GS and UC groups, respectively; p < .001). Serious complications were more frequent in the GS group: 154 (75.9%) vs 60 (56.1%) in the UC group; p < .001. No significant differences were observed between groups regarding readmissions, and in-hospital and post-discharge (1 year follow-up) mortality. CONCLUSIONS: Despite the poorer clinical condition of patients in the GS group, the CGA-based intervention resulted in a lower incidence of delirium and other geriatric syndromes compared with the UC group.

New species of Pseudoscorpiones (Arachnida) from tree hollows in a Mediterranean oak forest in Spain.

Pseudoscorpions inhabiting mature Quercus pyrenaica Willd. trees have been surveyed using hollow emergence traps and window traps in Salamanca, Spain. Three new species are described: Neobisium (N.) hispanicum Zaragoza Hernández-Corral, n. sp., Rhacochelifer gaeli Zaragoza Hernández-Corral, n. sp. and Rhacochelifer nonidezi Zaragoza Hernández-Corral, n. sp. The genera Amblyolpium Simon, 1898 and Beierochelifer Mahnert, 1977 and the species Amblyolpium dollfusi Simon, 1898 and Beierochelifer peloponnesiacus (Beier, 1929) are new records for the Iberian Peninsula. Beierochelifer peloponnesiacus jonicus (Beier, 1932) is shown to be a junior subjective synonym of B. peloponnesiacus n. syn. New regional records of five other species belonging to the families Cheliferidae, Chernetidae and Withiidae are given. Keys are given for the species of the genera Pseudorhacochelifer Beier, 1976 and Rhacochelifer Beier, 1932 with elongated keels on posterolateral corners of carapace and anterior tergites in males, and for the Rhacochelifer species of the Iberian Peninsula. Complementary data to the description of the female syntypes from Caravaca (Murcia, mainland Spain) and males from the Canary Islands of Rhacochelifer pinicola (Nonídez, 1917) are given. Brief redescriptions of the female of Neobisium (N.) maroccanum Beier, 1930 and the male of Rhacochelifer euboicus Mahnert, 1977 are provided. The previous record of R. disjunctus from Slovakia is shown to be an error for R. euboicus. New data on the distribution and habitats of species of Cheliferidae, Chernetidae and Withiidae are given.

A new Antillobisium species (Arachnida: Pseudoscorpiones: Bochicidae) from Cuba, with biogeographical and ecological remarks on the genus.

A new troglobitic species of the genus Antillobisium is described from Sancti Spiritus province, Cuba. Antillobisium tomasi n. sp. is the third known species of the genus and is well characterized by its large size and extremely slender appendages. Biogeographical and ecological considerations on the genus are given.

Revision of the Ephippiochthonius complex in the Iberian Peninsula, Balearic Islands and Macaronesia, with proposed changes to the status of the Chthonius subgenera (Pseudoscorpiones, Chthoniidae).

A taxonomic revision of the subgenus Chthonius (Ephippiochthonius) in the Iberian Peninsula, Balearic Islands and    Macaronesia is presented. New and previously insufficiently studied characteristics are shown to be taxonomically useful, such as the chelal lyrifissures patterns, chaetotaxy and condylar complex. Three taxa previously treated as subgenera of Chthonius are here raised to generic rank: Ephippiochthonius n. stat., Globochthonius n. stat., and Hesperochthonius n. stat. Two new genera are described: Cantabrochthonius n. gen. and Occidenchthonius n. gen. Thirty-five new species are described: Ephippiochthonius aini n. sp., E. andalucia n. sp., E. aurouxi n. sp., E. benimaquia n. sp., E. caceresi n. sp., E. castellonensis n. sp., E. comasi n. sp., E. fadriquei n. sp., E. galcerani n. sp., E. gonzalezi n. sp., E. henderickxi n. sp., E. ibiza n. sp., E. masoae n. sp., E. portugalensis n. sp., E. riberai n. sp., E. serengei n. sp., E. sevai n. sp., E. tarraconensis n. sp., E. vicenae n. sp., E. zaballosi n. sp., Occidenchthonius anae n. sp., O. beieri n. sp., O. ebo n. sp., O. felgueraorum n. sp., O. gardinii n. sp., O. hoerwegi n. sp., O. lencinai n. sp., O. mahnerti n. sp., O. mateui n. sp., O. montagudi n. sp., O. murcia n. sp., O. oromii n. sp., O. ortunoi n. sp., O. riopar n. sp. and O. serranoi n. sp. A neotype is designated for Ephippiochthonius catalonicus (Beier, 1939), n. comb. As result of the changes in generic rank, 45 new combinations for species are proposed.
