FURTHER STUDIES ON THE TREMATODE GENUS HIMASTHLA WITH DESCRIPTIONS OF H. MCINTOSHI N. SP., H. PISCICOLA N. SP., AND STAGES IN THE LIFE-HISTORY OF H. COMPACTA N. SP

Helicotylenchus oleae n. sp. and H. neopaxilli n. sp. (Hoplolaimidae), Two New Spiral Nematodes Parasitic on Olive Trees in Italy.

Helicotylenchus oleae n. sp. and H. neopaxilli n. sp., from olive roots and soil in Italy, are described and illustrated. Helicotylenchus oleae can be distinguished from the related species H. canadensis and H. tunisiensis especially by the smaller styler, its distinctive tail shape, and a tail longer than one anal body width. Helicotylenchus neopaxilli differs from the close species H. paxilli...

The life history of Echinostoma paraensei sp. n. (Trematoda: Echinostomatidae).

The life history of Echinostoma paraensei, a new Brazilian species with 37 collar spines, has been completed experimentally. The planorbid snail Biomphalaria glabrata serves as first intermediate host, and intramolluscan stages also develop in Physa rivalis. Sporocysts usually develop in the heart. Rediae are of two types, distinguishable by large or small pharynges. Cercariae released 25 or mo...

m at h . SP ] 2 0 Ju n 20 05 THE MIURA MAP ON THE LINE

We study relations between properties of the Miura map r 7→ q = B(r) = r + r and Schrödinger operators Lq = −d/dx + q where r and q are real-valued functions or distributions (possibly not decaying at infinity) from various classes. In particular, we study B as a map from L loc (R) to the local Sobolev space H loc (R) and the restriction of B to the Sobolev spaces H(R) with β ≥ 0. For example, ...

Paracomesoma minor sp. n. and Microlaimus validus sp. n. (Nematoda) from the coast of Vietnam.

Two nematode species isolated from sediments of the littoral zone of South China Sea on the coast of Vietnam are described and illustrated. Paracomesoma minor sp. n. is closely related to P. elegans Gagarin & Thanh, 2009 and P. lissum Gagarin & Thanh, 2009. It differs from the former species in the shorter body, longer and more slender tail, longer cephalic setae and shorter spicules, and from ...
