larvae are easily distinguished from other apogonids by the presence of yellow chromatophores on the first dorsal and pelvic fins and usually melanophores on some portion of the pelvic fin. The yellow fin pigment typically disappears about the same time as the blotch of melanophores appears on the caudal peduncle, and here we separate larval and juvenile stages based on this transition in pigment. This also corresponds well with settlement from the plankton, as most of our net-collected larvae that have caudalpeduncle pigment do not have the pigment well defined as it is in juveniles and adults. Diagnostic features of the species are given below.
