Deronectes costipennis gignouxorum Fery & Brancucci, 1989

Incorrect original spelling: Deronectes costipennis gignouxi Fery & Brancucci, 1989:303 . Stated etymology: "This subspecies is dedicated to the Gignoux family (Toulon, Briançon)." Comment: As a family generally consists of more than one person and includes the male sex, and this specific name is explicitly based on the name of a family, the correct suffix is – orum.
