MILLIPEDS OF MEXICO AND CENTRAL AMERICA 65 



TYPE: Naturh. \lus. Wien. 



TYPE LOCALITY: Paraguay. 



In Attems 1933, p. 257, this species is listed, without additional 

 details, as found in Costa Rica. This fantastic extension of range is 

 quite improbable and it seems most likely that the Costa Rican speci- 

 men or specimens represent an undescribed species. Some additional 

 remarks on this species in South America were made by Jeekel 1963a, 

 p. 32. 



Genus ORTHOMORPHA Bollman 1893, p. 159. 



TYPE SPECIES: Polydesmus coarctatus Saussure, by original des- 

 ignation. 

 Orthomorpha coarctata (Saussure). 



Polydesmus coarctatus Saussure 1860, p. 207. 



TYPE: Mus. Hist. Nat. Geneve (H). 



TYPE LOCALITY: Considered to be in the Malay Archipelago. 



OTHER LOCALITIES: Tropicopolitan. Has been or probably will be 

 found in or near most large urban areas of Mexico and Central America. 



Extensive synonymy of this introduced genus and species is given by 

 Chamberlin and Hoffman 1958, and Jeekel 1963a. 

 Orthomorpha festae Silvestri 1896a, p. 4. 



TYPE: Mus. Zool. Royale, Torino (H). 



TYPE LOCALITY: Forest of the Rio Cianati, Darien Prov., Panama. 



Jeekel 1963a places this species in "species incertae sedis." I 

 believe it to be a euryurid, possibly of the genus Pseudamplinus. 



Genus OXIDUS Cook 1911c, p. 628. 



TYPE SPECIES: Fontaria gracilis Koch, by original designation. 

 Oxidus gracilis (Koch). 



Fontaria gracilis Koch 1847, p. 142; Cook 1911c, p. 631. 



TYPE: Location unknown (H). 



TYPE LOCALITY : Supposed to be East Indian but collected in a 

 greenhouse in Austria. 



OTHER LOCALITIES: Cosmopolitan in greenhouses; in the open in 

 much of Mexico and Central America. 



Full synonymy of this introduced genus and species is given in 

 Chamberlin and Hoffman 1958.
