Dear friends,

Together with colleagues, we are conducting research on the morphological consequences of elytra loss in beetles (see our recent study in Systematic Entomology: https://resjournals.onlinelibrary.wiley.com/doi/10.1111/syen.12617). We would be extremely grateful if you could share with us some specimens of key taxa with reduced elytra, especially:

Pachypus candidae (Scarabaeidae) – 2 pairs (dry or stored in alcohol)

Thylodrias contractus (Dermestidae) - 2 pairs (dry or stored in alcohol)

Micromalthus debilis (Micromalthidae) – 2 females (dry or stored in alcohol)

Hesperorhipis (Buprestidae) – 2 specimens (dry or stored in alcohol)

Carphurus (Melyridae) – 2 specimens (dry or stored in alcohol)

Diagrypnodes (Salpingidae) – 2 specimens (dry or stored in alcohol)

Conotelus (Nitidulidae) – 2 specimens (dry or stored in alcohol)

Vesperus (Vesperidae) – 2 paris (dry or stored in alcohol)

Best regards,

Jakub
