Two new species of Oswaldocruzia, O. manuensis sp. nov., and O. urubambaensis sp. nov. are described and illustrated from Peru, these are parasites of the cane toad Rhinella marina. O. manuensis is characterized by having cervical alae which are not well developed, ridges without chitinous supports, caudal bursa type II and branches of fork of dissimilar length. O. urubambaensis is characterized by a caudal bursa of type I, ridges with chitinous supports, a thin cephalic vesicle and origin of rays 9 in tip of the dorsal trunk.

The genus Xenotrichobius Wenzel, 1976 is revised using specimens collected in Venezuela and Peru. X. noctilionis Wenzel, 1976 is redescribed including the puparium. The new species, X. linaresi sp. n., differs from type species in size and shape of male genitalia, and longer setae on dorso-lateral connexivum. Xenotrichobius sp., a single female, has 1 pair of macrosetae in the epiproct and Xenotrichobius sp., a single male, characterized by longitudinal median and transverse mesonotal sutures joined, are described. Close relationships among Xenotrichobius, Paradyschiria Speiser, 1900 and Noctiliostrebla Wenzel, 1966 is supposed, due to the structure of male genitalia, the development of proctiger, and the shape of puparium. A key for the species is given.

Two species and one subspecies are described as new: Trichobius machadoallisoni sp. n., from Pteronotus personatus, is a member of caecus group, and closely related to T. bilobus Wenzel, 1976; however, T. machadoallisoni has the syntergite 1+2 lightly convex and with more than 21 setae. Trichobius anducei sp. n., from Carollia perspicillata, a member of parasiticus complex, differs from all other species in having a strip of long lateral connexival setae, in the number and position of setae in tergite 7 and epiproct in females, in the shape of gonopods, the number of setae in syntergosternite 7+8 and tergite 9 in males. Trichobius dugesioides phyllostomus subsp. n., from Phyllostomus elongatus differs from T. d. dugesioides Wenzel, 1966 in having more denticles in male gonopods and longer posterior setae in the tergite 7 of females. Trichobius d. dugesioides is redescribed, showing sexual dimorphism in distribution of microtrichia in the presutural area of scutum. Some morphotypes of Trichobius joblingi Wenzel, 1966 are compared with Trichobius persimilis Wenzel, 1976, reducing geographical distribution of the latter to the North of Orinoco river.

The present study analyses the helminth communities found in one hundred and two specimens of Martes martes from the Iberian Peninsula and the Balearic Archipelago. The component community is constituted by seventeen helminth species, which frequency and mean abundance show a bimodal pattern. The set of core species is constituted by the trichurids Pearsonema plica, Eucoleus aerophilus and Aonchotheca putorii (72.2% of total helminth individuals found), while the remaining can be considered satellite species. Significant co-occurrences were found among E. aerophilus/A. putorii and E. aerophilus/P. plica. These results demonstrate the great importance of earthworms within the diet of pine marten and contribute to the knowledge of the pine marten’s food ethology, since this kind of prey normally goes undetected in diet studies. Several helminth species, as Sobolevingylus petrowi, Centrorhynchus aluconis, Uncinaria criniformis, Mastophorus muris and Spirura rytipleurites seurati seem to show geographical distributions limited to insular ecosystems. Moreover, helminth communities of M. martes among four Spanish territories, including mainland and insular areas, are characterized and compared.
