Název v původním jazyce

Larval Pseudoproleptus sp. (Nematoda: Cystidicolidae) found in the Amazon river prawn Macrobrachium amazonicum (Decapoda: Palaemonidae) in Brazil

Popis výsledku v původním jazyce

Previously undescribed infective larvae of the cystidicolid nematode Pseudoproleptus cf. izecksohni (Fabio, 1982) comb. n., a parasite of freshwater fish in Brazil, were found encapsulated in the haemocoel of the Amazon river prawn Macrobrachium amazonicum (Heller) (Decapoda: Palaemonidae) from the natural canal in the Mexiana Island (Amazon River Delta), Pará State, Brazil; the prevalence in prawns (body length 48-110 mm) examined in March 2008 (n = 44) was 32%, with the intensity 1-6 (mean 2) larvae per crustacean. The nematode larvae (body length 19.71-25.65 mm), characterized by the cephalic end provided with a helmet-like cuticular structure having a thickened free posterior margin, are described based on light and scanning electron microscopy. Apparently prawns play a role as intermediate hosts of this nematode species. This is the first record of a larval representative of Cystidicolidae in South America and the first record of a species of Pseudoproleptus in the Neotropics.
