查看更多>>摘要:The present report is based on findings of occasional survey work conducted from the region spanning over six years for the presence of insect parasitic nematodes under the superfamily Thelastomatoidea (Nematoda: Oxyurida), parasitic in invertebrate hosts. Out of five families recognized under the superfamily, the present report discusses the findings of four families from Manipur and its adjoining areas as well. For the first time, out of 15 taxa described in the text, seven species are described from the region, eight species reported. The findings of the study will help in understanding of the biodiversity status of insect parasitic nematodes of the region. Diagnosis of the genus, key to species and illustration with line diagrams and photomicrographs are provided in the manuscript.

It was found in shallow waters of the States of Ceara, Rio de Janeiro, Sao Paulo, Parana and Santa Catarina, and is probably invasive. The genus forms encrusting sheets on solid objects, such as seaweed basal stems, barnacle shells and artificial substrates. The new taxon has spindles, crosses and radiates in the outer layer of the coenenchyme, fused sclerites in the interior and the polyps are unarmed. The newgenus is compared with other taxa that have fused sclerites.

Upeneus itoui is most similar to the western Indian Ocean species, U. pori. The caudal-fin color pattern infresh and preserved specimens of the two species is identical. However, U. itoui differs from U. pori in having less head and body depths, wider barbels, and a lower count of gill rakers.

The new taxa is characterized by: multi-serial (5-8 rows) placement of hydrothecae on both stem andbranches; a hydrothecal rim with four small cusps; an operculum with four equal flaps similar to but more flattened than that of Sertularella. Gonothecae are transversely corrugated and resemble those of many species assigned to Sertu-larella and Symplectoscyphus. They arise from hydrothecae-like tubes on the basal part of the stem and are disposed in opposite pairs, as in species of Synthecium.
