Diplurinae.-Brachythele : Greece, Cyprus, Central Asia. Macrothelinae.-Macrothele : Spain, China, L00CI100. Phyxio-schcema : Transcaspia. Brach y bothriidae.-Acattyma: Japan. Atypidae.-A typus : South and Central Europe, Algeria, Japan. Calommata: Japan. Cyrtaucheniidae.-Nemesia: S. Europe, N. Africa, China. Ane-mesia: Afghanistan. Cyrtauchenius : Southern countries of Mediterranean. Amblyocarenum : S. Europe, N. Africa. Ctenizidae.-Pachylomerus : Spain, Algeria, Japan. Idiops : Syria. Cteniza : France, Italy. JEpycephalus : Sicily, Sardinia. Cyrtocarenum: Eastern countries of Mediterranean. Sterrhochrotus : Turkestan. Latouchia : Loo Choo Islands, China. Halonoproctidae.-Halonoproctus : China. Barychelidae.-Leptopelma: S. Italy, N. Africa. Aviculariidse. Aviculariinae.- Ischnocolus : S. Europe, N. Africa. Crator-rhagus and Chaztopelma : Eastern area of Mediterranean. Of the above-mentioned genera, 22 in number, those belonging to the Aviculariidae and Barychelidae are peculiar; alsotiterrhochrotus, Cyrtocarenum, JEpycephalus, and Cteniza amongst the Ctenizidae; Cyrtauchenius, Anemesia, and Nemesia amongst the Cyrtau-cheniidae; Phyxioschcema amongst the Dipluridae ; and perhaps Acattyma amongst the Brachybothriidae. Of the others, Brachythele and Amblyocarenum are also Sonoran ; Macrothele and Latouchia also Oriental; A typus, Oriental and Sonoran; Calommata, Oriental and Ethiopian ; Pachylomerus, Sonoran and Neotropical; Idiops, Oriental, Ethiopian, and Neotropical. Thus of the 22 genera enumerated, more than half, namely 12, are peculiar. Of the rest, 4 are Sonoran and 5 Oriental, the latter, with exception of Idiops, occurring in the Indo-Chinese area ; 2 Ethiopian and 2 Neotropical. With the Australian Region the Mediterranean has no genera in common, although Porrhothele and Stenygrocercus of the former are nearly related to Macrothele and Phyxioschcema of the latter. These data make it impossible to attach the MediteiTanean area to either of the others with which it has genera in common. Hence it must be regarded as a Region apart. The only genus which extends into the Holarctic is A typus. It may be defined as the Region lying north of the Ethiopian and Oriental Regions, and south of the great mountain-chains of Europe, north of which the Mygalomorphae, excepting Atypus, do not pass. |
