A new family (Macronicophilidae) is established for Macronicophilus Silvestri, 1909, currently placed in Geophilidae. Seven new species of Neotropical Geophilomorpha are described: ltyphilus saucius n.sp. and I. sensibilis n.sp. ( Ballophilidae), Hyphydrophilus projectus n.sp. and Ribautia onycophaena n.sp. (Geophilidae), Macronicophilus abbreviatus n.sp., M. unguiseta n.sp. and M. venezolanus n.sp. (Macronicophilidae). The hitherto unknown male of Schendylops marchantariae (Pereira, Minelli \& Barbieri, 1995) is described and two species (Pectiniunguis geayi (Br\ölemann \& Ribaut, 1911) and ltyphilus calinus Chamberlin, 1957 are redescribed from the type and new material. A key to the species of Macronicophilus is provided.

Among the least studied clade of velvet worms (Onychophora) is a clade of Neotropical Peripatidae (=Neopatida). Neopatida has been traditionally divided into an Andicoles group and a Cara\ïbes group, which now correspond to Oroperipatus and the remaining genera, respectively. Panama is located in a unique position bridging the faunas of both clades and of two large continents, both of which host an important diversity of velvet worms, yet taxonomic study of the Panamanian onychophorans has been largely neglected. In this study we critically evaluate the onychophoran diversity of Panama, redescribe a species from the former Canal Zone and describe a new species from the Pacific side, close to Costa Rica, as Epiperipatus bernali sp. nov., with a unique combination of characters visible under the SEM. We further discuss the existence of multiple lineages of Onychophora in Panama, both from the Andicoles and Cara\ïbes groups, and within the latter, with connections to different lineages, both from South and Central America.

Cormocephalus (C.) guildingii Newport, 1845\—one of the oldest names in this genus\—is described in detail for the first time, based on material from Western Mexico, Jamaica and the Dominican Republic; the range of this species is much expanded. Synonymy of C. impressus Porat, 1876 under C. guildingii is analyzed and confirmed. Relations between the latter and both C. ungulatus (Meinert, 1886) and C. andinus (Kraepelin, 1903) are analysed in detail. Both C. mundus Chamberlin, 1955 and C. (Cupipes) tingonus Chamberlin, 1957 are junior synonyms of C. ungulatus (Meinert, 1886). Cormocephalus mediosulcatus Attems, 1928 is suggested to be transferred to the genus Scolopendropsis as S. thayeri (Meinert, 1886) syn. nov. A new subclade (designated as the \“guildingii-subgroup\”) is established within the Neotropical clade of the genus Cormocephalus. It includes most Neotropical representatives of the gervaisianus species-group (sensu Schileyko \& Stagl 2004) united by nine diagnostic synapomorphies. Relations within the new subclade are analysed and its diagnosis is given.

A review of Pycnotropis is presented, with the description of 14 new species: P. goeldii n.sp., P. madeira n.sp., P. sigma n.sp. and P. urucu n.sp., all from Brazil, P. carli n.sp. from Ecuador, P. curvata n.sp., P. falcata n.sp., P. jeekeli n.sp., P. pallidicornis n.sp., P. similis n.sp., P. subfalcata n. sp., P. unapi n.sp., P. torresi n.sp. and P. zumbii n.sp., all from Peru. P. acuticollis (ATTEMS, 1899), is redescribed upon the holotype from Brazil. Based on abundant strictly topotypic material, P. tida (CHAMBERLIN, 1941), is considered as a subjective senior synonym of P. epiclysmus HOFFMAN, 1995 (syn.n.). A key has been compiled to all 26 species of this diverse genus, with notes on its distribution.

Twenty caves located in a high altitudinal quartzite area in Brazil were examined for invertebrate richness and composition and in terms of environmental factors that determine community structure. We evaluate how distance, altitude, cave extension, environmental stability, number and size of cave entrances and stream presence can act on species composition and richness. The caves presented a high richness of troglophilic (463 spp.) and troglobitic species (6 spp.) in relation to other siliciclastic caves around the world. The average richness was 39.55 species per cave (sd = 21.87), the quantitative similarity among caves was 41\% and turnover was \βrepl. = 0.769. Araneae (20\% of the sampled species), Diptera (18\%) and Coleoptera (14\%) were the dominant orders regarding species richness. Only twenty percent of the caves were placed out of the confidence interval of the average taxonomic distinctness (∆+); however, the ∆+ decreased with the increase of environmental stability. Cave extension and stream presence were the main factors determining the variation of species composition among caves. Cave extension also influenced species richness variations. Furthermore, the total richness and richness of troglobitic species increased with cave extension. The threats to these habitats further revealed that the fauna is at risk due to tourism, trampling and natural soil erosion that can promote microhabitat alterations. Therefore, quartzite caves also require special attention regarding conservation actions in order to keep their natural biological dynamics.

The genus Newportia Gervais, 1847, includes some 60 nominal species distributed in the Caribbean islands and from Mexico to central South America. Modern keys to species and subspecies are available, greatly fa\­cilitating identification, but some species are based on few specimens and have incomplete documentation of taxonomically-informative characters. In order to explore genetic variability and evolutionary relationships within geographically-widespread morphospecies, specimens of N. (N.) stolli (Pocock, 1896) and N. (N.) divergens Chamberlin, 1922, two nominal species distinguished principally by differences in suture patterns on T1, were sequenced for mitochondrial 16S rRNA and cytochrome c oxidase subunit I (COI) genes from populations in southern Mexico, Guatemala, Honduras and Brazil. N. (N.) stolli is paraphyletic with respect to N. (N.) divergens within a clade from Guatemala, Honduras, and Chiapas (Mexico), most trees being consistent with a single loss of a connection between the anterior transverse suture on T1, whereas specimens of \“N. (N.) stolli\” from Brazil are not closely allied to those from the Mesomerican type area. The widespread morphospecies N. (N.) monticola Pocock, 1890, was sequenced for the same loci from populations in Costa Rica, Colombia and Brazil, finding that specimens from these areas do not unite as a monophyletic group. Samples of N. (N.) oreina Chamberlin, 1915, from different regions of Mexico form geographic clusters that resolve as each other\’s closest relatives. These results suggest that some widespread species of Newportia maybe taxa of convenience more so than natural groupings. In several cases geographic proximity fits the phylog\­eny better than taxonomy, suggesting that non-monophyletic species do not result from use of inappropriate molecular markers. Molecular identification is possible for specimens missing taxonomically informative morphological characters, notably damaged specimens that lack the ultimate leg pair, a protocol that may also apply to other taxonomically difficult genera that are prone to damage (such as Cryptops).
