Interspecific variation in the microanatomy of cosmetid harvestmen (Arachnida, Opiliones, Laniatores)
There are several microanatomical structures associated with the ocularium, dorsal scutum, male chelicera, and pedipalp that could represent informative phylogenetic characters in future taxonomic studies of cosmetid harvestmen. Expand
Comparative Study of the Microanatomy of Four Species of Harvestmen (Opiliones, Eupnoi)
Using scanning electron microscopy, the morphology of somatic and reproductive structures of Neotropical taxa were compared with that of a temperate sclerosomatid species, Leiobunum formosum, and interspecific variation in the surface texture of the cuticle and the distribution of setae on the body and appendages was observed.

Survey of cuticular structures on leg IV of cosmetid harvestmen (Opiliones: Laniatores: Gonyleptoidea)
The results indicate that there is considerable interspecific variation in rough pit glands and the tarsal perforated organ among cosmetid and gonyleptoidean harvestmen. Expand
A mineralogical and fluid inclusion study of the Patricia Zn-Pb-Ag Deposit ( Paguanta , NE Chile )
The Patricia Zn-Pb-Ag ore deposit is located within the Paguanta mining project, situated at the northern end of the Andean Oligocene Porphyry Copper Belt of Chile. The sulfide mineralization occursExpand
