Kearn, Graham C., Whittington, Ian D. & Evans-Gowing, Richard, 2007, A revision of Entobdella Blainville in Lamarck, 1818, with special emphasis on the nominal (type) species “ Entobdella hippoglossi (Müller, 1776) Blainville, 1818 ” (Monogenea: Capsalidae: Entobdellinae) from teleost flatfishes, with descriptions of three new species and a new genus, Zootaxa 1659, pp. 1-54 : 44-45

Entobdella brattstroemi Brinkmann, 1952

( Figs. 15H, 35)

Type host and locality: Fine flounder, Paralichthys adspersus (Steindachner, 1867) ( Pleuronectiformes : Paralichthyidae ); Pacific Ocean, off coast of Chile, Golfo de Ancud, N of Isla Abtoa, 41°47'18" S, 73°20'55" W, depth 60 m ( Brinkmann 1952a).

Other locality: Coquimbo (approximately 29°57' S, 71°25' W), approximately 1300 km north of type locality. Specimens collected by Dr M. T. González ( Entobdella sp. 2 ; Table 2) .

Site on host: Skin.

Holotype: Adult specimen already designated by Brinkmann (1952a) ( SMNH No.: LUCE type 3864; M107, 1 slide).

Voucher specimens: 2 adult specimens ( SAMA AHC No 29195, 2 slides) from P. adspersus off Coquimbo, Chile ( Entobdella sp. 2 : Table 2).

Specimens studied: Holotype and voucher specimens listed above.

Redescription ( Fig. 35): See also Brinkmann (1952a). In present study, based on holotype and 2 vouchers (see above): total length 4403 (3971 – 5191) (n = 3); body width 3335 (2873 – 4003) (n = 3); haptor length and breadth 2265 (2045 – 2587) and 2345 (2088 – 2797) respectively (n = 3); length of accessory sclerite 312 (282 – 355) (n = 5); length of anterior hamulus 877 (698 – 963) (n = 5); length of posterior hamulus 146 (121 – 170) (n = 4); pharynx length and width 428 (345 – 500) and 635 (478 – 738) respectively (n = 3); testis length and width 286 (250 – 331) and 536 (506 – 563) respectively (n = 3). Accessory sclerites stout with strongly developed and characteristically shaped flanges along inner and outer borders of curved distal third ( Figs. 15H, 35B). Outer flange wider than inner flange.

Differential diagnosis: Distinguished from other Entobdella spp. by characteristic shape of accessory sclerites ( Figs. 15H, 35B). On skin of Paralichthys adspersus .

Comments. The holotype of E. brattstroemi is in a poor condition – in particular the shapes of the accessory sclerites are hard to resolve. The 2 specimens donated by Dr González ( Entobdella sp. 2 ; Table 2) are in good condition and are lodged as vouchers at the SAMA (see above). The type locality is approximately 1300 km south of Coquimbo where Dr González collected her specimens.

Although the specimens recently acquired by us came from a locality 1300 km north of the type locality, they are from the same host as Brinkmann’s specimen, namely Paralichthys adspersus , and this, together with the similarly shaped accessory sclerites, indicates that the 3 studied specimens are conspecific.
