“…larger than basal teeth (smaller in P. erehwon and P. extra) [6]. This last feature also was reported to P. cassagnaui from France [56] (p. 183, Figure 15), but the new species clearly differs from it by eyes absent (1 in P. cassagnaui), Th II with 2 mac (absent in P. cassagnaui), tenent hairs capitate (acuminate in P. cassagnaui), and unguis a.t. present (absent in P. cassagnaui). Description.…”

“…It is also not clear if the dorsal pattern of macrochaetotaxy is useful to support ingroups of Pseudosinella since the same patterns occur in different species regardless of the shape of the unguis and unguiculus [24,32,50,52,56]. Even though such patterns are similar among remarkably different species, Holarctic taxa tend to have a larger number of macrochaetae [7,52,56] while the Holotropical species hold a smaller number of them, as seen in most of the Brazilian new species. Curiously, the dorsal macrochaetae reduction in tropical species was also reported to other Entomobryidae genera like Seira and Lepidocyrtus [16,36,71] and it may represent some trend in the adaptation to tropical areas, possibly related to high temperature.…”

Herein, eyeless Pseudosinella species from Brazilian caves are reviewed, including the description of 23 new species, new records plus additional notes on the descriptions of P. ambigua Zeppelini, Brito, and Lima and of P. guanhaensis Zeppelini, Brito, and Lima. We also provide an identification key to 27 eyeless species recorded from Brazil. To organize the 26 Brazilian eyeless taxa analyzed in this work, we organize them in apparently artificial groups: 11 species have one larger tooth on the unguiculus outer lamella (petterseni group); one presents unguiculus outer lamella smooth or serrated (never with a larger tooth), with 9 held prelabral chaetae undivided and the last 6 held prelabral chaetae bifurcated. The Brazilian species of eyeless Pseudosinella herein described present a remarkably conservate dorsal chaetotaxy; therefore, the main diagnostic characters are related to other features like prelabral, labral, and ventral head chaetotaxy and empodial complex morphology. In addition, our study suggests that Brazilian caves possibly shelter a great diversity of Pseudosinella taxa, several of them potentially cave dependent.

“…In addition, the Gisin (1965Gisin ( , 1967aGisin ( , 1967b four special leaf-shaped sensilla present on Ant IV in the new species separate it from its most similar species. With the same dorsal macrochaetotaxy, but without chaeta 's' on Abd II, there are six species: P. alpina Gisin, 1950 (one eye); P. astronomica Gisin & Gama, 1970 (one eye); P. christiani Stomp, 1986 (without eyes); P. mucronata Gouze & Deharveng, 1987 (five or six); P. thibaudi Stomp, 1977 (two eyes); and P. vandeli relicta Gisin, 1964 (no eyes). The differences between these nine species and the new species are shown in Table 1.…”

This paper describes Pseudosinella altamirensissp. nov. from the Altamira Caves, municipal district of Santillana del Mar (Cantabria, Spain), and five other caves near the coast of Cantabria (northern Spain). Its taxonomic position is discussed and differences and similarities among morphologically and geographically close species are highlighted. The new species can be identified by its five eyes, the basal and small inner paired teeth on the claw, and the length of the uncrenulated part of the distal dens.

“…Dorsal median macrochetae are distributed as e.g. in Pseudosinella infrequens and Pseudosinella impediens Gisin et Da Gama, 1969. Next to these median macro chaetae there is a transversal row of 7 macrochaetae directed to the lateral margin (Fig.…”

This, together with an average 74 inch rainfall, has yielded an abundance of caves. Over 700 caves have been catalogued. Most of these occur in the White Limestone formation of Oligocene age, which reaches a thickness up 2,000 feet. The White Limestone is underlain by middle Eocene Yellow Limestone and is folded along an east-west axis. Fewer caves have been formed in Cretaceous limestone, gypsum deposits, sub recent raised coral rock, and post-Miocene limestone ( Figure 1). The Limestone plateau of central Jamaica is favoured for cave development because of its watershed which has a gentle gradient off the 1,500 to 3,000 feet high insoluableCentral The Invertebrate Fauna of TropicalInlier. This metamorphic ridge separates the limestone plateau into two main watersheds and the water running north or south disappears in numerous sinkholes and closed valleys in the extremely porous White Limestone (Figure 2).The purposes of this paper are several: to bring together the scattered literature on the physical speleology of Jamaica; to bring together the little that has been published on Jamaican biospeleology; to give a general summary of the knowledge of the fauna resulting from my field work; and to make available descriptive data on the cave sites that have been biologically studied. A complete listing of the fauna of Jamaican caves and a synthesis of the ecology, evolution, and zoogeography of this fauna will be published in a much later paper, after the many necessary taxonomic studies are completed. REVIEWThere have been many publications on Jamaican karst and hydrology. General' references on Jamaican caves, cave exploration, karst, and hydrology are those of Aley (1964), Ashcroft (1969), Read (1963), Smi...
