New host and geographical records are reported 
  for the nematode Lappetascaris lutjani 
  Rasheed, 1965, parasitizing the marine fish Trachipterus 
  arawatae Clark, 1881 in Brazilian waters. 
  Morphometric data and illustrations of the parasites are included.  
Key words: Nematoda - Lappetascaris lutjani 
  - Pisces - Trachipterus arawatae - Brazil 
The genus Lappetascaris was erected by 
  Rasheed (1965), to contain the anisakid nematode L. lutjani, recovered 
  from the intestine of the marine fishes Lutjanus sp. [Lutjanidae] and 
  Tenualosa ilisha (Hamilton, 1822) (= Hilsa ilisha) [Clupeidae], 
  captured on the Karachi Coast, Pakistan. Additionally, the species was reported 
  in India parasitizing Kurtus indicus Bloch, 1786 [Kurtidae] (De et al. 
  1978), Ilisha feligera (Valenciennes, 1847) [Clupeidae] (Soota & 
  Dey-Sarkar 1980), and Pellona ditchela Valenciennes, 1847 [Clupeidae] 
  (De 1990).  
The present paper reports a new host and a new 
  locality for L. lutjani.  
Morphometric data are based on four adult specimens, 
  two males and two females. Processing of nematodes for study was in accordance 
  with Pinto et al. (2001). Measurements are in millimeters (mm), unless otherwise 
  indicated. Figures were made with the aid of a drawing tube connected to an 
  Olympus microscope and the photomicrograph with a Axiophot Differential Interference 
  Contrast (DIC) system.  
Lappetascaris lutjani Rasheed, 1965 
  

  (Figs 1-3, 4) 
   
Body slender, brownish yellow in color, and attenuated 
  at the anterior extremity. Cuticle thick. Head heavily cuticularized appearing 
  as a mass of small cuticular thickenings (Fig. 
  4) rather than a three-lipped structure (Fig. 
  1). Lateral alae 0.14 wide.  
Males: body 5.4-5.5 cm long, 0.26-0.37 wide. 
  Nerve ring and excretory pore 0.42-0.49 and 0.49-0.56 from anterior end, respectively. 
  Esophagus 6.79-8.40 long. Intestinal caecum and esophageal appendix, 6.37-6.44 
  and 3.01-3.94 long, respectively. Ventriculus 0.10-0.12 long. Spicules 3.92-4.00 
  long. Sixteen to seventeen pairs of caudal papillae. Cloacal aperture 0.56-0.63 
  from posterior extremity.  
Females: body 7.5-8.5 cm long, 0.68-0.84 wide. 
  Nerve ring and excretory pore 0.49 and 0.63 from anterior end, respectively. 
  Esophagus 8.47 long. Intestinal caecum and esophageal appendix, 6.58 and 3.08-4.20 
  long, respectively. Ventriculus 0.12 long. Vulvar aperture in the middle region 
  of body. Rectum 0.36-0.56 long. Anus 0.58-0.77 from posterior end.  
Taxonomic summary 
Host: Trachipterus arawatae Clark, 
  1881, Lampridiformes, Trachipteridae; common names: dealfish, "peixe-fita" 
  – New host record 
Voucher host deposited: Museu Oceanográfico 
  do Vale do Itajaí (MOVI) no.16160, female, 1,680 mm long, SL (Standard 
  length) 
Site of infection: stomach  
Locality: Atlantic Coast (29°22'S, 47°38'W, 
  50 m depth), State of Rio Grande do Sul, Brazil – New locality record  

Specimens deposited: Helminthological Collection 
  of the Oswaldo Cruz Institute (CHIOC) no. 34435 (wet material) and MOVI no. 
  16663 (wet material).  
According to Mincarone et al. (2000), the host 
  species T. arawatae has been recorded in Africa, Australia, New Zealand, Réunion 
  Island and Atlantic coast of South America.  
The present results add new data to previous 
  surveys of Brazilian fish nematodes (Vicente et al. 1985, Vicente & Pinto 
  1999).
