Arachnologische Mitteilungen 55

Giovanni Canestrini’s arachnological collection in Padova 39 species (Tab. 2). The syntype of the valid species Neobisium ( = Obisium ) dolicodactylum (Canestrini, 1874) was examined by Callaini (1985), but it was absent from the collection du ring the cataloguing work. The three specimens collected by Balzan in Paraguay comprise Gomphochernes (= Chernes ) com- munis (Balzan, 1888) (Chernetidae), Paratemnoides (= Cher- nes ) nidificator (Balzan, 1888) (Atemnidae) and Chernes cap- reolus Balzan, 1888 = Lustrochernes argentinus (Thorell, 1877) (Chernetidae), all of which seem to appertain to the original type series. Scorpiones and Solifugae The scorpions, collected almost exclusively from Italy, partly constituted the basis for the monograph on Italian scorpions published by Fanzago (1872), since several localities in the pu blication match those given in the catalogue. In fact, Canest rini never dedicated himself to scorpions, as demonstrated by the few specimens preserved in his collection, and left them to his pupil Fanzago who generalized the knowledge on these arachnids in Italy (Canestrini 1875b). In the collection, five specimens of Euscorpius (= Scorpius ) canestrinii (Fanzago 1872) (Euscorpiidae) are preserved that almost certainly appertain to the original type series. Vachon (1978) described two spe cimens of this species belonging to the “Collection Canestri ni” and deposited at the Hungarian Natural History Museum (Budapest), consequently designated by Kovarik (1997) as a lectotype and paralectotype. It is likely that these specimens were donated to the Museum in Budapest by Canestrini from the same syntype series currently deposited in Padova. The collection also contains a single solifuge from Egypt, a Rhagodidae, Pocock, 1897, identified by Canestrini as Solpuga melanus Savigny.This specimen has not yet been re-examined. Opiliones The harvestmen collection was revised by Chemini (1986) and includes specimens from Italy and France, the latter col lected by Eugène Simon. According to the historical cata logue, the first harvestmen material was registered in 1870; the last material was registered in 1875. In his pioneer works on harvestmen (Canestrini 1871, 1872a, 1872b, 1872c, 1873, 1874, 1875a, 1875b, 1876, 1888), Canestrini described 17 species from Italy and South America, most of which are re presented by type series in the collection (Tab. 3). Acari The Canestrini Acaroteca consists of 438 microscope slides, most of which originated from Italy (especially from Veneto and Trentino) and to a lesser extent from Europe (i.e. France, Germany, Hungary and Sweden) and extra-European coun tries (i.e. Brazil, Eritrea). In several cases, the host from which the specimens were collected is also indicated (e.g. domestic and wild animals, humans, foods or plants). Along with the acaroteca, the acarological collection also includes 115 sam ples in ethanol and glycerine, which were partly reviewed by Valle (1955) and therefore not examined during our curato rial revision.
