The old genus Libitia Simon, 1879 of small Andean harvestmen is revisited. The monotypic genus Libitiella Roewer, 1947 is herein considered a junior subjective synonym of Libitia. Accordingly, Libitiella bipunctata (Sørensen, 1932) is restored to the combination Libitia bipunctata. The species Libitia cordata and Libitia bipunctata comb. -

There are records of glands that produce sexual pheromones that are released into the environment or applied directly on sexual partners. Within Opiliones (Arachnida), several harvestmen in the suborder Laniatores have sexually dimorphic glands on legs I and IV, the mode of use of which is recorded only in two species but their function is unknown: while walking, males rub the glands against the substrate or against their body. Here we test an alternative and non-exclusive hypothesis that the glands present on the legs of male Gryne perlata (Cosmetidae) produce contact pheromones used in mating. -

Early Lineages of Gonyleptidae (Arachnida Opiliones Laniatores)
Tropical Zoology 7: 343-353, 1994 Early lineages of Gonyleptidae (Arachnida Opiliones Laniatores) ADRIANo B. KuRY Escola de Ciencias Biol6gicas, Universidade do Rio de Janeiro, Rua Frei Caneca 94, Rio de Janeiro 20.211-040, RJ, Brazil Received 8 June 1993, accepted 18 December 1993 As result of cladistic methodology applied to the study of Gonyleptidae, four precocious branches are newly recognized in the phylogeny of the family. Three new subfamilies are proposed and diagnosed and a new concept is given for the Bout guyiinae Mello-Leitao 1923. Metasarcinae, a new subfamily is proposed for the Bolivian Metasarcus Roewer 1913 (formerly in Mitobatinae) and an undescribed Argentinean genus. Chaconatus Roewer 1929 (formerly in Prostygninae) is herein considered to be a new junior subjective synonym of Metasarcus. Heteropachylinae, a new subfamily is proposed for nine genera formerly described as Gonyleptinae or Pachylinae, and distributed along the Brazilian coast. Cobaniinae, a new subfamily is proposed for the genus Cobania Roewer 1913. Bourguyiinae should be the correct spelling of a subfamily name based on the generic name Bourguyia Mello-Leitao 1923. In the present new concept, four of its five genera are removed, while eight others are transferred from the Gonyleptinae, Pachylinae and Progonyleptoidellinae. To recon struct the phylogeny of Gonyleptic,lae, 16 morphological characters were analysed through HENNIG 86, providing a single most parsimonious cladogram of CI = 0. 77. The branching pattern obtained is: (Metasarcinae (Heteropachylinae (Cobaniinae (Bourguyiinae + the other Gonyleptidae))). Piresa angulispinosis H . Soares 1966 is newly referred to Mangaratiba Mello-Leitao 1940. KEY WORDS: Arachnida, Gonyleptidae, new subfamilies, cladistics, Neotropics. -

E-mail: [email protected] ABSTRACT. A new species of Pickeliana Mello-Leitão, 1932, P. albimaculata sp. nov.., is described from Jussari, Bahia, Brazil. It can be easily distinguished from the already described species by the presence of white spots on mesotergal area I and anal opercle. It is similar to P. pickeli Mello-Leitão, 1932 by the presence of a large, ventro- apical pointed tubercle on femora III-IV. A cladistic analysis was performed adding a new character to the available character matrix, the presence of a large and ventro-apical pointed tubercle on male femur IV. Accord- ing to this analysis, P. albimaculata sp. nov. is sister species of P. pickeli. Additionally, we present an identification key and an update on the geographical distribution of species of this genus in northeastern Brazil. KEY WORDS.

These glands pro- duce a variety of chemicals very specific to opilionid taxa of different taxonomic levels, and thus represent a model system to investigate the evolutionary traits in exocrine secretion chemistry across a phylogenetically old group of animals. The chemically best-studied opilionid group is certainly Laniatores, and currently available chemical data allow first hypotheses linking the phy- logeny of this group to the evolution of major chemical classes of secretion chemistry. Such hypotheses are essential to decide upon a best-fitting explanation of the distribution of scent-gland secretion -

Phylogenetic Analysis of Phalangida (Arachnida, Opiliones) Using Two Nuclear Protein-Encoding Genes Supports Monophyly of Palpatores
2001. The Journal of Arachnology 29:189±200 PHYLOGENETIC ANALYSIS OF PHALANGIDA (ARACHNIDA, OPILIONES) USING TWO NUCLEAR PROTEIN-ENCODING GENES SUPPORTS MONOPHYLY OF PALPATORES Jeffrey W. Shultz: Department of Entomology, University of Maryland, College Park, Maryland 20742 USA Jerome C. Regier: Center for Agricultural Biotechnology, University of Maryland Biotechnology Institute, College Park, Maryland 20742 USA ABSTRACT. Recent phylogenetic studies of Opiliones have shown that Cyphophthalmi and Phalangida (5 Palpatores 1 Laniatores) are sister groups, but higher relationships within Phalangida remain contro- versial. Current debate focuses on whether Palpatores (5 Caddoidea 1 Phalangioidea 1 Ischyropsalidoidea 1 Troguloidea) is monophyletic or paraphyletic, with Ischyropsalidoidea 1 Troguloidea (5 Dyspnoi) being more closely related to Laniatores. The latter hypothesis was favored in recent combined studies of ri- bosomal DNA and morphology. Here higher relationships within Phalangida are examined using two nuclear protein-encoding genes, elongation factor-1a (EF-1a) and RNA polymerase II (Pol II), from 27 opilion species representing seven superfamilies. Cyphophthalmi was used as the outgroup. Nucleotide and inferred amino acid sequences were analyzed using maximum-parsimony and maximum-likelihood methods. All analyses recovered Palpatores as the monophyletic sister group to Laniatores with moderate to strong empirical support. Most palpatorean superfamilies were also recovered, but relationships among them were ambiguous or weakly -
