This paper provides the commented list of the 824 type specimens of stick-insects of the collection of the Muséum national d’Histoire naturelle of Paris, corresponding to 319 species (including 287 currently valid species). The catalogue was made together with the digitalization and the databasing of the collection; it comes with an electronic document illustrating all of the specimens which were processed. Lectotypes are here designated for six species (Anisacantha albogeniculata Redtenbacher, 1906; Bacteria maroniensis Chopard, 1911; Gongylopus adiposus Brunner von Wattenwyl, 1907; Gratidia nimbana Chopard, 1955; Parectatosoma mocquerysi Finot, 1898 Tropidoderus exiguus Redtenbacher, 1908), and Oxyartes spinulosus Redtenbacher, 1908 is restored as a valid species.

During three trips to French Guiana in 2000, 2002 and 2004, Florian Thévenot caught various species of Arthropods, including some Mantids. We intend to learn a little more about these Mantids with their identification and their distribution. One of them, Angela guyanensis Rehn, 1906 (Angelidae), has enabled us to carry out a breeding operation that has never been done before.

This article is like a notebook of a trip and give a non exhaustive list of the animals met in various places of the South of the metropolitan France.
Spiders are not like toys, neither necessarely animals without any danger, so we must be carreful when handling, that which not stop potential risk of accidents. Some accidents are exposed here and also some advices to limit them.

We try to review the taxonomy and the distribution of three species and some subspecies of Flower beetles of the genus Mecynorrhinella Marais & Holm, 1992. The biology of those Beetles is widely explained.
This article is interested mainly in the biology of the South African Cricket Phaeophilacris bredoides Kaltenbach, 1986. Otherwise, we are looking for its taxonomical statut that looked doubtful to us.
During a travel in French Guyana, Florian Thévenot has getting two Whip-spiders species of the genera Heterophrynus Pocock, 1894 and Charinus Simon, 1892. We look to know more on their real identity and on their biology. Hatching and growth of young Charinus have been studied.

During a travel in French Guyana, one of our c olleagues has coming back with some Painted ghost Crab from the genus Uca Leach, 181 4. We are both interessed by their complex taxonomy and by their biology which is very attracting
The distribution and the taxonomy of the spider Heteropoda venatoria ( Linné, 1767) are studied and put into question as it looks like several species are being mixed up. The biology of this spider is dealt with more particularly as well as the legends which refers to it.
The taxonomy, the distribution and the biology of the African horned Cetonid Eudicella gralli (Buquet, 1836) (Insecta : Coleoptera : Cetoniidae). We try to know more on the distribution of the Cetonid culture stock of Eudicella gralli (Buquet, 1836) as well as on the number of valid sub-species known in breeding. Its biology is largely studied.

Remarks about Medaura Stål, 1875 and of a new species in this genus, and review of an article describing 19 new species of Thai Stick-insects.
During some world travels, before all in La Réunion and in french Guyana, Florian Thévenot captured some Arthropods in order to study them. The author offers to study the StickInsects and their biogeography, one species from La Réunion : Monandroptera acanthomera (Burmeister, 1838) and six other from French Guyana : Citrina servillei Redtenbacher, 1908, Creoxylus spinosus (Fabricius, 1775), Phanocloidea muricata (Burmeister, 1838), Prexaspes Stål, 1875 sp., Pseudophasma phthisicum (Linnaeus, 1758), Stratocles tessullatus (Olivier, 1792).

Aretaon asperrimus is a beautiful spiny stick insect which is present in breeding since 1990. We tempt of in to know a few more on its taxonomy. A short description is followed of its distribution and its rearing. But we are interested mainly in the particular habits of this Species as the genes protection in copulatory phases, of the fights between males, because it gives out the sounds and the perception of the sounds in general in the stick insects. Finally, we finish with the defence possibilities of this Species in front of a possible predator.

This article deals with the taxonomy, the distribution and before all with the biology of the Andamans Stick-insect Sceptrophasma hispidulum (Wood-Mason, 1873). Clonaria luethyi (Zompro, 2000) and Sceptrophasma hispidulum eggs are compared and then follows a discussion about them.
The author deals with the taxonomy, biogeography and biology of three species of Asian stick insects belonging to the genus Phaenopharos Kirby, 1904 : Phaenopharos herwaardeni Hennemann, Conle & Brückner, 1996 ; P. khaoyaiensis Zompro, 2000 et P. struthioneus (Westwood, 1859). A determination key is given for the three species.
The author deals with two species of Asian Stick-insects belonging to the genus Medaura Stål, 1875 : Medaura jobrensis Brock & Cliquennois, 2001 and M. scabriuscula (Wood-Mason, 1873). He deals with their taxonomy, their biogeography and especially with their biology. Some notes concern the two other species of known Medaura : M. austeni (Wood-Mason, 1875) and M. makassarinus (Westwood, 1859). A determination key is given for the only two species of Medaura which seem to be valid taxa.

A new species of leaf insect is described from Thailand, Phyllium (Pulchriphyllium) maethoraniae n. sp., very close to P. (Pulchriphyllium) sinense Liu, 1990, but differs by various distinct characters such as the armature of the mesonotum, shape of the anterior legs, abdomen and abdominal apex. Like P. sinense, P. maethoraniae n. sp. is only known from the female. A table is given to distinguish between the two species.
The Harvestmen Dicranopalpus caudatus Dresco, 1948 is discovered again in France 50 years later (SANKEY & STOREY, 1969) and listed for the first time in the Eastern Pyrenees (66).
Different Stick-insects species of the genus Decidia Stål, 1875 are presented. A new species is described for the first time from Ecuador: Decidia macrocercata n. sp.. Currently only the male is known. An identification key for all Decidia male species is given.

The French harvestmen fauna includes 3 species of the genus Opilio Herbst, 1798 : O. canestrinii (Thorell, 1876), O. parietinus (De Geer, 1778) and O. saxatilis C.L. Koch, 1839. We propose an identification key and a synthesis of their geographical distribution which include new data, with the aim of making their study easier. O. canestrinii has been recorded for the first time in north-western France, in the Seine-Maritime department.
24 species of Harvestmen have been recorded in various metropolitan French localities. Details of the catching areas are given.
This book begin by a brief general introduction to the world of Opiliones. It give a presentation of the main useful bibliographic references to study French Opiliones, and the methods of capture and collection. It give also a commented list of known and potentially existing species in Northern France, which include the following regions: Alsace, Franche-Comté, Lorraine, Champagne-Ardenne, Burgundy, Nord-Pas-de-Calais, Picardie, Ile-de-France, Haute-Normandie, Basse-Normandie, Centre, Brittany and Pays de la Loire. Presently, 40 species have been formally found in the concerned area, and 15 other taxa are potentially present in the same. The necessary morphological criteria to identify species are detailed. We give identification keys for the 55 quoted taxa: a key of harvestmen families and keys of species for each family. These identification keys have been written and ordered to be practical to use; more than 210 figures, of which the majority are colored magnified pictures, are included. Moreover, 11 « index cards » of easier identification on the basis of three criteria are given for 10 taxa. The included keys will be also useful to identify the Opiliones fauna of surrounding countries like Belgium and the Luxemburg. The aim of this book is not to be a final and complete work on the identification of French Opiliones; its main aim is simply to encourage invertebrist who don't know this group to begin observation and determination of these arachnids, which remains poorly studied in France.
