Key to the Western Himalayan species of Cryphalus Erichson, 1836

1 Pronotal summit distinctly raised, placed on basal forth and asperities arranged in distinct concentric rows gradually spreading anteriorly............................................................................................ 2

- Pronotal summit not so raised, placed below the middle and with rather confused asperities not arranged in well-defined concentric rows....................................................................................... 3

2 Summit slightly behind the middle; median pair of asperities on anterior margin of pronotum much larger..................................................................................................... C. fulmineus Wood

- Summit placed closer to the base; anterior pronotal margin with asperities nearly of same size...... C. strohmeyeri Stebbing

3 Female frons with fine, weakly converging aciculations; anterior margin armed with 4–6 serrations.. C. mangiferae Stebbing

- Female frons with median transverse carina; anterior pronotal margin with four asperities............................ 4

4 Pronotal anterior two-third with more than 50 asperities; asperities distinctly sharp and longer, moderately spaced............................................................................................ C. himalayensis sp. n.

- Pronotal anterior two-third with distinct and longer asperities, but less numerous and less dense (30–35)...................................................................................................... C. major Stebbing
