Haliotrema striatohamus Zhukov, 1981 was redescribed and transferred to Haliotrematoides Kritsky, Yang & Sun, 2009 by Mendoza-Franco et al. (2009) as Hal. striatohamus based on specimens collected from the haemulids, H. aurolineatum , H. plumieri , and Haemulon sciurus (Shaw, 1803) from the southern coast of Quintana Roo, Mexico. This species is characterized in part, in having two accessory sclerites [4 (4-5; 6) long], at the tip of the superficial root of each the ventral anchor.
In the present study, partial molecular sequences (726-746 bp) of the 28S rRNA gene (D1-D3) of Hal. striatohamus are provided for the ﬁrst time. These sequences shows that Hal. striatohamus collected from Campeche is a sister species of the clade containing Hal. guttati and Haliotrematoides spinatus Kritsky & Mendoza-Franco, 2009 (see Figure 1) from L. guttatus off Taboga Island (type locality) and Perlas Archipielago in Pacific waters of Panama ( Kritsky et al. 2009b).
Twelve reference specimens (CNHE 10612).
Two slides, each containing a haptor of a specimen of Hal. striatohamus used to amplify its DNA are deposited in the CNHE (10623).
Representative DNA sequence.
