RESUMO
Spelaeobochica mahnerti sp. n., found in a limestone cave located in the municipality of Monjolos (Minas Gerais state, Southeastern Brazil), is described. It differs from congeneric species mainly by the rallum with 3 apically dentate blades, the position of the trichobothrium ib in the far distal half of the hand dorsum (near the base of fixed finger), the smooth subterminal setae, and by the arolia that are a little longer than the claws. A key to the species of Spelaeobochica is provided, as well as information on the habitat and threats for this new species. We further discuss troglomorphic traits in Brazilian species of Bochicidae.

Bacteria associated with the parthenogenetic troglobiont sand fly Deanemyia maruaga were characterized by sequencing cloned 16S rDNA PCR products. Eleven novel partial 16S rDNA sequences, with varying degrees of similarity to Actinobacteria, were identified. None of the sequences identified had homology to those known from parthenogenesis-inducing bacteria.

Spiripockia punctatais a new genus and species of Pomatiopsidae found in a cave from Serra Ramalho, SW Bahia, Brazil. The taxon is troglobiont (restricted to subterranean realm), and is characterized by the shell weakly elongated, fragile, translucent, normally sculptured by pustules with periostracum hair on tip of pustules; peristome highly expanded; umbilicus opened; radular rachidian with 6 apical and 3 pairs of lateral cusps; osphradium short, arched; gill filaments with rounded tip; prostate flattened, with vas deferens inserting subterminally; penis duct narrow and weakly sinuous; pallial oviduct simple anteriorly, possessing convoluted bypass connecting base of bulged portion of transition between visceral and pallial oviducts with base of seminal receptacle; spermathecal duct complete, originated from albumen gland. The description of this endemic species may raise protective environmental actions to that cave and to the Serra Ramalho Karst area.
Spiripockia punctata é gênero e espécie novos de Pomatiopsidae encontrado em uma caverna da Serra Ramalho, SW Bahia, Brasil. O táxon é troglóbio (restrito à vida subterrânea), caracterizado pela concha levemente alongada, frágil, translúcida, normalmente esculturada por pústulas contendo pelos do perióstraco no topo das pústulas; perístoma altamente expandido; umbílico aberto; dente raquidiano da rádula com 6 cúspides apicais e 3 pares de basais; osfrádio curto e curvo; filamentos branquiais com topo arredondado; próstata achatada, com vaso deferente inserindo subterminalmente; ducto do pênis fracamente sinuoso; oviduto palial anteriormente simples, possuindo um by-pass convoluto da base da porção bulbosa da porção entre oviduto visceral e palial com a base do receptáculo seminal; ducto da espermateca completo, originado da glândula de albume. A descrição dessa espécie endêmica deve contribuir com ações protetivas do ambiente da caverna e à área da Serra Ramalho.
