Fig 3
Photographs, X-rays and sole pigmentation patterns of type and comparative material included for both morphological and molecular comparisons in this study.
Ethanol fixation used for all specimens–type material 99.5% and comparative material 70%. Scale bars equal 10 mm (A–F). A, Monacoa niger, new species, holotype, CBM-ZF 14683. Note the strong pigmentation along the entire sole (anterior part partly damaged). B, Monacoa grimaldii, ZMUB 18926, (B* newly caught with specimen shown in Fig 1B). C, M. grimaldii, ZMUB 18977 (anterior part partly damaged). D, Monacoa griseus, new species, holotype, CBM-ZF 14677. E, M. griseus, new species, paratype, CBM-ZF 14681 (anterior part partly damaged). F, M. griseus, new species, paratype, CBM-ZF 14757 (juvenile). Insert shows protruding rectal organ being particular distinct in juveniles compared to adults.
