Onychophora, Peripatidae) Feeding on a Theraphosid Spider (Araneae, Theraphosidae)
2009. The Journal of Arachnology 37:116–117 SHORT COMMUNICATION First record of an onychophoran (Onychophora, Peripatidae) feeding on a theraphosid spider (Araneae, Theraphosidae) Sidclay C. Dias and Nancy F. Lo-Man-Hung: Museu Paraense Emı´lio Goeldi, Laborato´rio de Aracnologia, C.P. 399, 66017-970, Bele´m, Para´, Brazil. E-mail: [email protected] Abstract. A velvet worm (Peripatus sp., Peripatidae) was observed and photographed while feeding on a theraphosid spider, Hapalopus butantan (Pe´rez-Miles, 1998). The present note is the first report of an onychophoran feeding on ‘‘giant’’ spider. Keywords: Prey behavior, velvet worm, spider Onychophorans, or velvet worms, are organisms whose behavior on the floor forests (pers. obs.). Onychophorans are capable of preying remains poorly understood due to their cryptic lifestyle (New 1995) on animals their own size, although the quantity of glue used in an attack and by the fact they are rare in the Neotropics (Mcglynn & Kelley increases up to about 80% of the total capacity for larger prey (Read & 1999). Consequently reports on hitherto unknown aspects of the Hughes 1987). It may be that encounters with larger prey items, such as biology and life history of onychophorans are urgently needed. that observed by us, are more common than previously supposed. Onychophorans are almost all carnivores that prey on small invertebrates such as snails, isopods, earth worms, termites, and other ACKNOWLEDGMENTS small insects (Hamer et al. 1997). They are widely distributed in Thanks to G. Machado (USP), T.A. Gardner (Universidade southern hemisphere temperate regions and in the tropics (Reinhard Federal de Lavras), and C.A. -
Onychophorology, the Study of Velvet Worms

They capture prey with an adhesive net that is formed in a fraction of a second. The first naturalist to formally describe them was Lansdown Guilding (1797-1831), a British priest from the Caribbean island of Saint Vincent. His life is as little known as the history of the field he initiated, Onychophorology. This is the first general history of Onychophorology, which has been divided into half-century periods. The beginning, 1826-1879, was characterized by studies from former students of famous naturalists like Cuvier and von Baer. This generation included Milne-Edwards and Blanchard, and studies were done mostly in France, Britain, and Germany. In the 1880-1929 period, research was concentrated on anatomy, behavior, biogeography, and ecology; and it is in this period when Bouvier published his mammoth monograph. -

Entomologie, Martin-Luther-King Pfalz 3, D-2000 Hamburg 13 Abstract: What is a modern monograph? The problem is tackled on the basis of a discussion of the compli- cated taxonomy of Onychophora. At first glance the phylum presents a very uniform phenotype, which led to the popular taxonomic use of the generic name "Peripatus" for all representatives of the group. The first description of an onychophoran, as an "aberrant mollusc", was published in 1826 by GUILDING: To date, about 100 species have been described, and Australian colleagues (BRISCOE & TAIT, in prep.), using al- lozyme electrophoretic techniques, have discovered large numbers of genetically isolated populations of as yet un- described Peripatopsidae. The taxonomic hislory is reviewed in brief. Following the principles of SIMPSON, MAYR, HENNIG and others, selected taxonomic characters are discussed and evaluated. Questions arise such as: how can the pioneer classification (sensu SEDGWICK, POCOCK, and BOUVIER) be improved? New approaches towards a modern monographic account are considered, including the use of SEM and TEM and biochemical methods. -

Not only do the different classes of animals vary in the details of their relationships to the present land masses and their subdivisions, but great diversity is often found between families of the same order, and even between genera of the same family. Particularly is this true of nocturnal as contrasted with related diurnal types. As a group the onychophores have been strangely neglected by zoologists. -
Distribution of a Costa Rican Wet Forest Velvet Worm (Onychophora: Peripatidae)
ECOLOGY AND POPULATION BIOLOGY Distribution of a Costa Rican Wet Forest Velvet Worm (Onychophora: Peripatidae) 1 2 T. P. MCGLYNN AND C. D. KELLEY Ann. Entomol. Soc. Am. 92(1): 53Ð55 (1999) ABSTRACT The ecology of New World onychophorans is poorly known because individuals are rare and difÞcult to locate in the Þeld. The only descriptions of density and microhabitat associations are based on the Þeld observations of a few individuals. This paper presents the results of a 300-m2 search of leaf litter in a wet tropical forest at La Selva Biological Station, Republic of Costa Rica, during the dry season over a period of 4 mo. Density of this Epiperipatus sp. was 0.11 individuals per square meter. The age structure of the population was biased toward juveniles, but did not include newly born onychophorans; this suggests that reproduction occurs during the wet season. Epiperi- patus sp. nonrandomly selects microhabitats. It is strikingly associated with ants; 1-m2 plots con- taining onychophorans contained a mean of 7.4 ant nests, whereas plots without onychophorans had a mean of only 4.7 ant nests. In 2 instances, onychophorans were located inside large and active ant nests. KEY WORDS Epiperipatus, microhabitat, ants, leaf litter THE PHYLOGENY AND historical biogeography of the present the density, size distribution, and microhabi- phylum Onychophora are important to invertebrate tat selection of Epiperipatus sp. in a tropical wet forest systematists because of many traits shared with ar- in Costa Rica.

Abstract: Onychophorans, or velvet worms, are poorly known and rare animals. Here we report the discovery of a new species that is also the largest onychophoran found so far, a 22cm long female from the Caribbean coastal forest of Costa Rica. Specimens were examined with Scanning Electron Microscopy; Peripatus solorzanoi sp. nov., is diagnosed as follows: primary papillae convex and conical with rounded bases, with more than 18 scale ranks. Apical section large, spherical, with a basal diameter of at least 20 ranks. Apical piece with 6-7 scale ranks. Outer blade 1 principal tooth, 1 accessory tooth, 1 vestigial accessory tooth (formula: 1/1/1); inner blade 1 principal tooth, 1 accessory tooth, 1 rudimentary accessory tooth, 9 to 10 denticles (formula: 1/1/1/9-10). Accessory tooth blunt in both blades. Four pads in the fourth and fifth oncopods; 4th. pad arched. The previ- ously unknown mechanism by which onychophorans weave their adhesive is simple: muscular action produces a swinging movement of the adhesive-spelling organs; as a result, the streams cross in mid air, weaving the net. -

Reproductive Trends, Habitat Type and Body Characteristics in Velvet Worms Onychophora)
Rev. Bicl.Trop.42L3: 611-622. 1994 Reproductive trends, habitat type and body characteristics in velvet worms Onychophora) Julián Monge-Nájera Centro de Investigación General, (UNED. Mailing address: Biología Tropical. Universidad de Costa Rica. San José. Costa Rica (Rec. 4-VII-1994. Acep. 5-IX-1994) Abstract: A quantitative analysis of several onychophoran characteristics shows that in habitats with lower rain levels females reproduce at an older age, are more fecund and tend to have reproductive diapause where rain does not exceed a mean of 200 cm/year. These habitat characteristics are associated with the southern family Peripatopsidae. Sex ratio and parental investment per young are not correlated with general environmental conditions. A comparison of 72 species showed that larger species are often more variable in morphometry, but species with the longest females do not always have the longest males. Larger Peripatus acacioi females (Peripatidae: Brazil) produce more and heavier off spring. Intrapopulation morphology was studied in 12 peripatid species for which samples of between II and 798 individuals were available. In general, within populations the females are more variable than males in’ length and weight, but similarly variable in the number of legs. The number of legs has a low variability (1.73- 2.45%). length is intermediate (22.4-25.3%) and weight is very variable (49.41-75.17%). When sexes are compared within a population, females can have 14-8.9 % more leg pairs, and be 47-63 % heavier and 26 % longer than males. Key words: Body siz.e. sex ratio, parental investment, legs, length, weight, evolutionary ecology.
