M1AtewnJifuseum 1 oxftates. PUBLISHED BY THE AMERICAN MUSEUM OF NATURAL HISTORY CENTRAL PARK WEST AT 79TH STREET, NEW YORK 24, N.Y. NUMBER i8oo OCTOBER i6, 1956 Pseudoscorpions of the Family Cher- netidae from New Mexico BY C. CLAYTON HOFF' The present paper is the third of a series on the classification and dis- tribution of the pseudoscorpions of New Mexico and is concerned with the monosphyronid pseudoscorpions exclusive of the Cheliferidae. Two genera and eight species are described as new, three species are recorded for the first time from New Mexico, and previously unreported state records are given for two other species. In order to make the account of the pseudoscorpions of New Mexico more useful, brief discussions are given of the higher taxa of monosphyronid pseudoscorpions exclusive of the Cheliferidae and attention is called to the possibility of eventually finding additional groups represented in the New Mexico fauna. The Cheliferidae will be discussed in the fourth paper of this series. Most of the collections reported here were made from 1947 to 1955, during which time the writer was favored by financial aid from faculty research grants from the University of New Mexico and grants from the American Academy of Arts and Sciences and from the National Science Foundation. Pseudoscorpions reported as associated with rodents in Santa Fe County are from collections made available by Harvey B. Morlan, Sanitarian, United States Public Health Service. These collec- tions were taken in connection with studies on rodent ecology at the Santa Fe, New Mexico, Field Station of the United States Department of Health, Education, and Welfare. -

ARANEOL., 14 (2021) SPIDERS FROM MYANMAR AND A BEITR. ARANEOL., PAPER ON EXTANT SPIDERS FROM Joerg Wunderlich (ed.) PORTUGAL (ARACHNIDA: ARANEAE) In this paper I (JW) try to round off the “trinity of fossil spider faunas” of three vanished worlds: of the Dominican, Baltic and Burmese (Kachin) ambers (from ca. 22, 45 and 100 (!) million years ago), which I treated in about a dozen volumes concerning the most diverse group of predatory animals of this planet, the spiders (Araneae). We treat in short the cannibalism of few Cretaceous spiders and provide notes on their orb webs. The focus of this study is the diverse fauna of the higher strata which is preserved in Burmese (Kachin) amber. Probably as the most IMPORTANT GENERAL RESULTS I found the Mid Cretaceous Burmese spider fauna to be at least as diverse as the fauna of today but composed by quite different groups and – in contrast to most groups of insects - by numerous (more than 60 %) extinct families of which apparently not a single genus survived. I identified and described ca. 300 species (55 families) of spiders in Burmese (Kachin) amber and estimate that probably more than three thousand spider species lived 100 million years ago in this ancient forest which was a tropical rain forest. What will be the number of spider species (and other animals) that survives the next 100 years in the endangered rain forest of today in Myanmar? A second IMPORTANT GENERAL RESULT: probably during the last 60-70 million years ancient spider groups of the “Middle age of the Earth” (the Mesozoicum) were largely displaced by derived members of the Orb weavers like the well- known Garden Spider (as well as other members of the superfamily Araneoidea) and by spiders like Jumping Spiders, House Spiders and Wolf Spiders (members of the “RTA-clade”) which are very diverse and frequent today. -

Malcolm College of Arts and Science s Pacific University Forest Grove, Oregon 9711 6 ABSTRAC T The diagnosis of the genus Illinichernes Hoff is revised and a new species, Illinichernes stephensi, is described from tree hollows in western Oregon ; the first Oregon state records are reported fo r Acuminochernes crassopalpus (Hoff), Dendrochernes crassus Hoff, Dinocheirus sicarius Chamberlin , D. validus (Banks), Hesperochernes utahensis Hoff and Clawson, and Lustrochernes grossus (Banks) , and Lamprochernes sp. These are the first published records from Oregon for the chernetid family. INTRODUCTION Chernetid pseudoscorpions have not been reported previously from Oregon eve n though approximately 80 species of the family are known from other parts of the Unite d States. A recent study of Oregon pseudoscorpions (Benedict 1978), based on newl y collected specimens and on specimens accumulated in various older collections, indicate s that chernetids are fairly common in Oregon habitats . Some of the specimens were readily identifiable as: Acuminochernes crassopalpus (Hoff), Dendrochernes crassus Hoff, Dinocheirus sicarius Chamberlin, D. validus (Banks), Hesperochernes utahensis Hoff and Clawson, and Lustrochernes grossus (Banks). Follow- ing examination of the type series of Illinichernes distinctus Hoff, the type species of the genus, Oregon specimens of Illinichernes were determined to represent a new species which is described in this paper . However, other specimens were more difficult to identify because many of the genera and species of this family are poorly defined . -

Christian Kropf: Natural History Museum, Department of Invertebrates, Bernastrasse 15, CH-3005 Bern, Switzerland. ABSTRACT. The present study reports for the first time on the behavior prior to, during and after the copulation of a member of the haplogyne spider family, Tetrablemmidae and describes the web of this species. Prior to copulation, male and female of Indicoblemma lannaianum from Thailand sometimes avoided each other or the female scared the male away, apparently by vigorous vibrations of her body. When first copulations were initiated, they lasted from 1.21 to 3.8 h with an average of 2.25 Ϯ 0.71 h (n ϭ 17). Some females accepted a second male for mating 3–9 days after first mating. There was no significant difference between the duration of first and second copulations but significantly more trials were needed to induce the second copulations. In the copulatory position, the male was inverted and faced in the same direction as the female. He seized the female’s opisthosoma with apophyses on his chelicerae which fit into grooves on a female’s ventral plate in this way building a locking mechanism during copulation. The pedipalps were inserted alternately. -

Arachnida, Araneae), a Spider Family Newly Recorded from China Yanfeng Tong, Shuqiang Liã
ARTICLE IN PRESS Organisms, Diversity & Evolution 8 (2008) 84–98 www.elsevier.de/ode Tetrablemmidae (Arachnida, Araneae), a spider family newly recorded from China Yanfeng Tong, Shuqiang Lià Institute of Zoology, Chinese Academy of Sciences, Beijing 100101, PR China Received 3 July 2006; accepted 16 January 2007 Abstract The family Tetrablemmidae is reported for the first time from China, with five new species and one new genus. Lehtinenia gen. n., which is erected to accommodate Lehtinenia bicornis sp. n., is characterized by the modified embolus, special modifications on chelicerae, and a Tetrablemma-type vulva. The other four new species are: Ablemma prominens sp. n., Brignoliella caligiformis sp. n., Brignoliella maoganensis sp. n., and Tetrablemma brevidens sp. n., all collected from caves. A phylogenetic analysis of the subfamily Tetrablemminae based on 41 morphological characters shows that the tribe Brignoliellini is the most basal group in the subfamily, rather than the sister group to the tribe Fallablemmini. Lehtinenia gen. n. and the genera Ablemma, Sulaimania, and Maijana together form a monophyletic group. r 2008 Gesellschaft fu¨r Biologische Systematik. Published by Elsevier GmbH.

Manley Department of Entomology, Michigan State University East Lansing, Michigan 48823 INTRODUCTION Berlese or Tullgren funnel methods of extraction of forest litter fauna often produce minute arthropods called pseudoscorpions. These are relatively com- mon but have received little attention. Because of the author's involvement with the Michigan State University soil zoology research project the potential signi- ficance of these animals has become a matter of interest. The Pictorial Key (Figs. 1 and 2) has been designed to assist in the identification of Michigan pseudoscorpions, and will be a useful starting point for further study of our species. -
