Another Little Red Beetle

Who has antennae like this? Reminds me of Ptilodactylidae, but they look completely different. Centro de Transferencia Tecnología y Educación Continua (CTEC) campus, San Carlos, Provincia de Alajuela, Costa Rica.

 

Newsflash: It's Ptilodactylidae after all! Thanks to borisb for the ID.
