Etymology: Diplotaxodon: Greek, diploos = twice + Greek, taxis = disposition + Greek, odous = teeth (Ref. 45335); longimaxilla: The specific name longimaxilla is derived from the Latin words maxilla, which means 'jaw', and longus, which means 'long', and is used here in reference to the long upper jaw bone (Ref. 127500).

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 14 - 15; Rückenflossenweichstrahlen (insgesamt) : 10 - 12; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 11 - 12. Diagnosis: The body depth distinguishes Diplotaxodon longimaxilla, 28.9-32.4% of standard length, from D. altus, 35.1-37.8% of standard length, D. limnothrissa, 22.5-27.8% of standard length, D. argenteus, 27.3-27.6% of standard length, and D. greenwoodi, 34.2-36.5% of standard length (Ref. 127500). Diplotaxodon longimaxilla, with horizontal eye diameter 27.1-32.1% of head length, has a smaller eye than D. macrops, horizontal eye diameter 35.2-38.2% of head length; the smaller cheek depth of D. longimaxilla, 15.2-19.4% of head length, distinguishes it from both D. aeneus, 23.2-28.1% of head length, and D. apogon, 23.2-28.0% of head length; it has more lateral-line scales than D. ecclesi, 35-38 vs. 32 (Ref. 127500).
This species is found offshore; common in trawl nets from depths below 80 m near Domira Bay (Ref. 127500).
