Etymology. Ulaikoilia jelineki sp. nov. is named in honour of our friend and colleague Josef Jelínek, a leading specialist on the family Nitidulidae , on the occassion of his 70th birthday.

Biology and collecting circumstances. The type locality is in a mosaic of primary and secondary forests in the Kau Wildlife Area located about 15 km north of Madang in the foothills of the Adalbert mountain range. The holotype was collected by a local collector involved in the whole project; it was probably beaten from vegetation.

Distribution. So far known only from the type locality in the Madang province in the northeastern part of Papua New Guinea.
