The northern South American genus Haematotropis Jeekel, 2000 is shown to presently encompass 21 species, all duly redescribed, illustrated, keyed, and mapped, including 13 new species: H. amazonica sp. nov. (Amazonas, Brazil), H. aripuanensis sp. nov. (Mato Grosso, Brazil), H. callyi sp. nov. (French Guiana), H. dentata sp. nov. (Maranh\ão, Brazil), H. disjunctoides sp. nov. (Par\á, Brazil), H. goeldii sp. nov. (Par\á, Brazil), H. jurutiensis sp. nov. (Par\á, Brazil), H. driki sp. nov. (Amazonas, Brazil), H. melgacensis sp. nov. (Par\á, Brazil), H. mosaica sp. nov. (Par\á, Brazil), H. paraensis sp. nov. (Par\á, Brazil), H. poranga sp. nov. (Par\á, Brazil) and H. tysoni sp. nov. (Amazonas, Brazil). New characters are used in all descriptions and redescriptions. Aphelidesmus guianensis Chamberlin, 1923, the type species of Ochrotropis Jeekel, 2000, is a new junior synonym of Aphelidesmus divergens Chamberlin, 1918, comb. nov. ex Ochrotropis in Haematotropis.

The co-occurrence of similar species in a particular environment may be facilitated if they specialise on different microhabitats, reducing competition between them. In some cases, two species prefer the same microhabitat, but one is competitively excluded to its harsh margins. In this study, we assessed microhabitat preferences and competition between two species of millipedes in Costa Rica. (1) We observed them in the wild and found Nyssodesmus python most often on wood, less often on leaves, and rarely on rocks. Spirobolida was found most often on leaves, less often on wood, and never on rocks. (2) We tested their preferences in the lab and found that N. python preferred wood to rocks, wood to leaves, and rocks to leaves. Spirobolida preferred leaves to rocks, leaves to wood, and wood to rocks. (3) We tested interference competition by placing both species together in an arena in which they both had the same preference (wood vs. rocks). Both species chose to cohabitate in the same wood, indicating that one species did not directly exclude the other. In N. python and Spirobolida, co-occurrence is facilitated by differences in microhabitat preferences and not because competition forces one species out of its preferred microhabitat.

Abstract: The Mexican millipede Euryurus flavocarinatus Daday, 1889, has remained as incertae sedis for over a century. Examination of the holotype shows that the species belongs to Amplinus, a genus of the large polydesmidan family Aphelidesmidae. Here, we present a full redescription of the holotype of Amplinus flavocarinatus (Daday, 1889) comb. nov. On the other hand, Euryurus flavocarinatus Silvestri, 1899 (currently included in the genus Pycnotropis) is a junior primary homonym of E. flavocarinatus Daday, 1889 and, to solve this issue, the name Pycnotropis silvestrii Recuero \& Aguado-Aranda new name is proposed to replace Silvestri\’s name.

Redescripci\ón y nueva combinaci\ón de Euryurus flavocarinatus Daday, 1889, y nuevo nombre para el hom\ónimo Euryurus flavocarinatus Silvestri, 1899 (Diplopoda, Polydesmida, Aphelidesmidae)

Resumen: El milpi\és mexicano Euryurus flavocarinatus Daday, 1889, ha permanecido como incertae sedis por m\ás de un siglo. El examen del holotipo demuestra que la especie pertenece al g\énero Amplinus dentro de la amplia familia Aphelidesmidae, orden Polydesmida. En el presente trabajo presentamos una redescripci\ón completa del holotipo de Amplinus flavocarinatus (Daday, 1889) comb. nov. Por otro lado, Euryurus flavocarinatus Silvestri, 1899 (actualmente cosiderada dentro del g\énero Pycnotropis) es un hom\ónimo primario m\ás reciente de E. flavocarinatus Daday, 1889, por lo que proponemos el nombre Pycnotropis silvestrii Recuero \& Aguado-Aranda nom. nov. para sustituir el nombre de Silvestri y resolver la homonimia.
