New species and subspecies Doliops Waterhouse, 1841 and Lamprobityle Heller, 1923 (Coleoptera: Cerambycidae) from the Philippines. Baltic J. Coleopterol., 18(2): 297– 304. New species and a new subspecies of the genus Doliops Waterhouse, 1841 and a new species of the genus Lamprobityle Heller, 1923 (Coleoptera: Cerambycidae) are described and illustrated: D. um sp. n., D. basilana zamboangana ssp. n. and L. medinai sp. n. The genus Doliops in the world fauna is now represented by 59 species, and the genus Lamprobityle by 13 species.

The new spe- cies differs from all other species of the genus with an unique, drawing of elytra and pronotum. The new species is somewhat similar to D. serapavginae Barševskis, 2014, from which it differs and with a different pattern of pronotum and elytra: first transverse band of a new species near stria with area without scales ( in D. serpavginae this spot is fully scaled), as well as second and third spots have different shapes. Etymology. The name of species is de- rived from the abbreviation of Univer- sity of Mindanao – UM. In last years thanks to the support of University President Guillermo Torres, Jr., this uni- versity is becoming one of the most im- portant Coleoptera research centers in the Philippines. It is a great honor for me to dedicate this beautiful species to the University of Mindanao as one of A B Fig. 1. Doliops um sp. n.
