Molecular phylogenetic analysis of 28S rRNA gene sequences of different genera of the Order Haplosclerida. The evolutionary history was inferred by using the Maximum Likelihood method based on the General Time Reversible model. The sequences were generated in this study or downloaded from Genbank. (A–C) Partial representations of the 28S rRNA C2-D2 gene tree. (A) phylogenetic position of Chalinula tamoiensis sp. nov. and Chalinula nematifera at Clade A; (B) phylogenetic position of Chalinula molitba at Clade A; (C) phylogenetic position of Chalinula milnei at Clade C. Sequences from the species Svenzea zeai (KC869635) and Scopalina ruetzleri (KC869553 were used to root the tree. Only bootstrap values above 65% are shown. UERJPOR 422: Voucher of the holotype of C. tamoiensis sp. nov.; UERJPOR 505: a paratype of the new species.	FIGURE 2.
