The ionic glands of Raillietiella sp. were investigated ultrastructurally in different ontogenetic stages. Modifications of the ultrastructure, number, and distribution of ionic glands were observed after the invasion of the primary larvae into the invertebrate intermediate host and after the invasion of the infective larvae into the vertebrate final ...

The ontogenetic development of the cephalobaenids Reighardia sternae and Raillietiella sp. was compared and considerable differences with regard to stage size, development terms, habitat preference, and feeding behavior were found. On the basis of these differences we present a new interpretation of the life cycle of R.

The ultrastructure of accessory genital glands in Raillietiella sp. is described and their function is discussed. In females we assume that they reactivate sperm, which are stored in the receptacula seminis after copulation. In males we think they are primer-pheromone glands, which inject secretions into the female during copulation and stimulate the ...

The pentastome Raillietiella indica was col- lected from the introduced toad Bufo marinus in Oahu, Hawaii, U.S.A. The parasite was identified as R. indica from similarities in morphology of the hooks, buccal cadre, and male copulatory spicule. This represents a new host record for this parasite, previously only recorded from Bufo melanostictus.

In Raillietiella sp. larvae we discovered a gland whose duct pores shed their secretion caudally of the mouth onto the integument. This gland type, which we call the suboral gland, seems to be characteristic of all pentastomid species. We discuss its possible function in the invasion of the larvae into the intermediate host.

Hypodermal gland cells in Raillietiella sp. represent a new cell type in pentastomids. They were discovered in infective larvae (intermediate host) and in juvenile raillietiellids (final host) during molting. The ultrastructural development of hypodermal gland cells is described in this report.

The midgut of Raillietiella sp. was investigated in different ontogenetic stages. The developing embryo, the hatched first-stage larva, the infective fourth-stage larva from the intermediate host, and juveniles and adults from the definitive host were viewed ultrastructurally.

Occurrence of β-chitin in the cuticle of a Pentastomid Raillietiella gowrii
Experientia, 1977The purified chitin from the cuticle of a pentastomid was examined by X-ray method. The X-ray photograph discloses that the chitin in question is of β-type. Since the arthropod cuticle contains α-chitin, it is suggested that Pentastomida may be considered an independent phylum.
