Abstract

FIGURE 1. Cladogram of relationships discussed in the text. Numbers indicate autapomorphies of Assiculus and Assiculoides, and unambiguous synapomorphies relating terminal taxa (modified from Springer et al. 1977, Godkin & Winterbottom 1985). Character: 1, parhypural not separate from hypurals 1 + 2; 2, total caudal-fin rays 27 or fewer; 3, infraorbital bones five or fewer; 4, pu 2 haemal spine attached to centrum; 5, opercle with prominent serrations ventral to subopercle junction; 6, anteroventral scale rows on posterior body and caudal peduncle oriented almost vertically; 7, dorsal fin connected to caudal fin by membrane; 8, hypural 5 reduced or absent; 9, pelvic-fin rays I, 4 or fewer; 10, at least some pelvic-fin rays unbranched; 11, only anterodorsal lateral line present; 12, hypochordal longitudinalis muscle inserts on only two caudal-fin rays; 13, palatine teeth absent; 14, lateral extrascapula attached firmly to skull; 15, posterior tip of infraorbital 5 does not contain anterior continuation of pterotic laterosensory canal; 16, supraoccipital crest reduced to ridge of bone; 17, pectoral-fin rays 15 or fewer; 18, opercular spine present; 19, epibranchial 1 plate-like; 20, branchiostegal membranes united; 21, caudal vertebrae 22 or more.
