|Identification||Hara filamentosa can be distinguished from congeners (except H. mesembrina and H. longissima) in sometimes having (vs. always lacking) a filamentous extension to the first principal ray of the upper caudal-fin lobe; it is also distinguished from all congeners except H. hara and H. longissima in having a short posterior process on coracoid (reaching to midway of distance between bases of pectoral spine and first pelvic-fin ray vs. two thirds or beyond; length 19.9-22.8% SL vs. 23.5-38.3). It differs from H. longissima in having a shorter (length 14.9-17.8% SL vs. 18.8-21.3) and deeper (depth 6.1-7.2% SL vs. 5.0-6.1) caudal peduncle (depth 2.1-2.9 times in its length for H. filamentosa vs. 3.1-3.9 times in H. longissima) and deeper body (depth 13.9-19.2% SL vs. 12.5-14.5). Hara filamentosa can be further distinguished from H. hara in having a longer adipose-fin base (15.7-21.7% SL vs. 11.8-15.6),deeper caudal peduncle (depth 6.1-7.2% SL vs. 5.0-5.8) and lacking (vs. presence) of serrations on the anterior edge of the dorsal spine, from H. horai in having a deeper caudal peduncle (depth 6.1-7.2% SL vs. 5.2-6.2) and a shorter adipose-fin base (length 5.7-21.7% SL vs. 10.0-13.7) and head (length 26.5-29.1% SL vs. 30.3-34.2), from H. jerdoni in having a shorter pectoral spine (length 23.3-29.9% SL vs. 42.2-51.7), more soft pectoral-fin rays (total number of soft fin rays modally 7 vs. 5), more vertebrae (31–34 vs. 27-29), the supraoccipital spine not reaching (vs. reaching) the anterior nuchal plate and a deeply forked (vs. emarginate) caudal fin. It differs from H. mesembrina in having a shorter caudal peduncle (length 14.9-17.8% SL vs. 17.2-18.9), from H. minuscula in having more soft pectoral-fin rays (total number of soft fin rays modally 7 vs. 5) and the supraoccipital spine not reaching (vs. reaching) the anterior nuchal plate, and from H. spinulus in having a longer dorsal spine (length 20.4-27.6% SL vs. 14.7-19.8), adipose-fin base (length 15.7-21.7% SL vs. 12.9-16.1) and caudal peduncle (length 14.9-17.8 % SL vs. 11.8-15.0).|
