Megacephalini Explained

Megacephalini is a tribe of big-headed tiger beetles in the family Cicindelidae.

Genera

These genera belong definitively to the tribe Megacephalini, as they are groups often placed within the type genus Megacephala itself:

• Grammognatha Motschulsky, 1850
• Megacephala Latreille, 1802
• Metriocheila Thomson, 1857
• Phaeoxantha Chaudoir, 1850
• Pseudotetracha Fleutiaux, 1894
• Tetracha Hope, 1838 (metallic tiger beetles)

These genera are of less certain placement or status:^[1]

• Aniara Hope, 1838 (probable synonym of Tetracha)
• Callidema Guérin-Méneville, 1843 (unrelated to other megacephalines)^[2]
• Cheiloxya Guerin-Meneville, 1855 (genetically unrelated to other megacephalines)
• †Cretotetracha Zhao et al., 2019 (fossil taxon of uncertain affinity)
• Oxycheila Dejean, 1825 (genetically unrelated to other megacephalines)
• †Oxycheilopsis Cassola & Werner, 2004 (fossil taxon of uncertain affinity)
• Pseudoxycheila Guerin-Meneville, 1839 (genetically unrelated to other megacephalines)
