FIGURE 1 in Two new species of Pseudoscopelus (Teleostei: Chiasmodontidae), with a new diagnosis for the genus

FIGURE 1. Morphometric landmarks on Pseudoscopelus, defined as follows: (1) tip of snout, at anterior edge of premaxilla; (2) posterior border of caudal peduncle, at insertion of caudal-fin rays; (3) posterior angle of opercle; (4) posterior tip of maxilla; (5) anterior tip of lower jaw, at symphysis of dentaries; (6) angle between angular and quadrate; (7) anterior margin of orbit; (8) posterior margin of orbit; (9) superior margin of orbit; (10) inferior margin of orbit; (11) anterior nostril; (12) posterior nostril; (13) groove at frontal, dorsal to eye, representing smallest infraorbital distance excluding infraorbital 6; (14) edge of frontal, at attachment of preopercle; (15) cheek point, at smallest distance between inferior margin of eye and ventral edge of cheek; (16) insertion of first pectoral-fin ray; (17) insertion of first pelvic-fin ray; (18) tip of longest pectoral-fin ray; (19) tip of longest pelvic-fin ray; (20) insertion of first ray of first dorsal fin; (21) insertion of last ray of first dorsal fin; (22) tip of second ray of first dorsal fin (usually longest); (23) insertion of first ray of second dorsal fin; (24) insertion of last ray of second dorsal fin; (25) tip of last unbranched ray of second dorsal fin (usually longest); (26) insertion of first ray of anal fin; (27) insertion of last ray of anal fin; (28) tip of last unbranched ray of anal fin (usually longest); (29) insertion of first dorsal procurrent caudal-fin ray; (30) insertion of first ventral procurrent caudal-fin ray.
