Present study.

L. synagris  and L. griseus 

Locality/prevalence, mean abundance and intensity range on L. synagris  .

San Francisco: 69 fish (mean TL 28.2 cm; range 20-35.7) infected of 70 examined (98.6%); abundance, 14; intensity of infection, 8-20 worms. Seyba Playa: 77 fish (TL 28.4; 19.2-30.5) infected of 79 examined (97.5 %); abundance, 15; intensity of infection, 11-22. Champoton: 75 fish (TL 28.2; 24.7-30.5) infected of 75 examined (100 %); abundance, 17; intensity of infection, 5-27.

Supplementary observations

(measurements based on twelve specimens on L. synagris  ). Body 518 (402-640; 12) long; greatest width 81 (65-100; 8). Haptor 74 (53-100; 8) wide. Pharynx 28 (20-35; n = 6) wide. Male copulatory organ (MCO) 40 (35-43; n = 11) long. Accessory piece 29 (28-31; 5) long. Proximal ring of the MCO 24 (19-33; n = 8) diameter. Ventral anchor 26 (23-28; 16) long; dorsal anchor 26 (21-30; 13) long. Ventral bar 36 (32-42; 8) long; dorsal bar 28 (25-32; 8) long. Hook 13 (11-13; 12) long.


This species was originally described as Haliotrema tubocirrus  from the gills of L. synagris  , L. analis  , L. apodus  , Lutjanus cyanopterus  (Cuvier, 1828) and Rhomboplites aurorubens  (Cuvier, 1829) from the environs of Havana, Cuba ( Zhukov 1976). Kritsky and Boeger (2002) transferred this species to Euryhaliotrema  based on the description and drawings provided in the original description by Zhukov (1976). Since then, E. tubocirrus  has been reported on other lutjanids [ Lutjanus vivanus  (Cuvier, 1828), L. griseus  and Lutjanus buccanella  (Cuvier, 1828), L. mahogoni  ] from Puerto Rico (see these reports in Kritsky 2012).

The present specimens were identified as E. tubocirrus  according to the redescription of this species made by Kritsky (2012) based on specimens found on other five lutjanids: Lutjanus campechanus  (Poey, 1860), L. griseus  , L. jocu  , L. synagris  and R. aurorubens  from the northern Gulf of Mexico (Mississippi coast and Florida). Euryhaliotrema tubocirrus  is characterized by having anchors with moderately developed superficial root, short deep root, slightly arced shaft, elongate  point, two complete rings in the MCO, and accessory piece multi-branched. Previous fish species reported as hosts of E. tubocirrus  were collected off Cuba (Area Havana), Puerto Rico and Mississippi coast and Florida in USA. Recently, Montoya-Mendoza et al. (2016) reported E. tubocirrus  (voucher CNHE 10222), from L. synagris  from Santiaguillo Reef, Veracruz (Gulf of Mexico). Examination of that voucher allowed us to confirm the conspecificity of present specimens with those collected by Montoya-Mendoza et al. (2016).

Specimens deposited.

Twelve reference specimens in the CNHE (10604).
