All material leg. Ioannis Karaouzas and all specimens are deposited in the collection of I. Karaouzas (Athens, Greece). Diagnostic features. Characterisation of the larvae was based on the presence or absence of gills on abdominal segment VII, pattern of the head (i.e., shape and colour of the frontoclypeal apotome) and submentum form of the last instar larvae (5th instar). Submentum, mentum, ventral apotome, and gular sclerite are names used for the same structure throughout the literature. Here, the commonly used name of submentum is employed ( Zamora-Muñoz et al . 1995 ; De Pietro 1999 ; Waringer & Graf 2011 ). Terminology of larval characters by Schefter & Wiggins (1986) and De Pietro (1999) is used. Photographs of the larvae were taken through a stereomicroscope (Olympus SZX7) with a built-in camera (Infinity 1).
