Remarks

Corydiinae is the most diverse and the most studied subfamily in Corydiidae ; even so, further studies are required. Rehn (1951) divided this subfamily into two tribes based on whether the female is winged ( Corydiini ) or not ( Polyphagini ). Grandcolas (1994) recognised 17 genera (including Cryptocercus ) and highlighted some problems with this subfamily. He noted Austropolyphaga and Polyphagoides should not belong to Corydiinae and questioned the North African genus Polyphagina (with only one species), considering it an Arenivaga species introduced from American deserts. But these problems have not yet been resolved. Roth (2003) listed 19 genera in this subfamily; he also questioned the status of Austropolyphaga and moved Leiopteroblatta , Mononychoblatta and Cryptocercus out of Corydiinae , and added Holocompsa , Hypercompsa and Euthyrrhapha . Before the present study, this subfamily contained 19 genera ( Beccaloni 2014); a systematic revision of this subfamily is still needed.

Key to the genera of Corydiinae in China

1. Antenna pectinate, only male is known ............................... ............................... Ctenoblatta - Antenna not pectinate ...................................................................................................................... 2

2. Female apterous (tribe Polyphagini ) .......................................................................................... 3 - Female macropterous or brachypterous (tribe Corydiini ) .................................................. 4

3. Male tegmina without Sc swelling; female large, pronotum with a white margin anteriorly, if not, body with large brownish-yellow markings ...................... Polyphaga

- Male tegmina with Sc swelling; female small- to medium-sized, pronotum without white margin, colouration ranges from brownish yellow to blackish brown, usually unicoloured, body sometimes with many small pale spots ...................... Eupolyphaga

4. Sexual dimorphism indistinct, usually metallic bluish green or blue, tegmina with bright yellow spots or band .......................................................................................... Eucorydia - Body small to large, pale coloured, usually yellowish brown to dark brown .......... 5

5. Female small (10 mm), pronotum moderately thick; male unknown ...... Minicorydia Female large (usually more than 25 mm), pronotum very thick; male wings with CuA circle .............................................................. ..............................................................
