Therates monticola Zettel & Pangantihon, 2017

Material examined. PHILIPPINES, Apayao Province, Municipality of Calanasan, 1♂, 3♀♀ Brgy. Tanglagan [18.3692°N, 120.9603°E], 2♂♂, Brgy. Parina [18.4291°N, 120.9713°E] IX–X.2018, coll. R.J. T. Villanueva ( Fig. 5B); UMCRC 010149, UMCRC 010150, UMCRC 010151, UMCRC 010152.

Identification. Therates monticola is easily distinguished by the color pattern of its elytra and its smaller size compared to the most similar species of Therates , namely T. fasciatus fasciatus (Fabricius, 1801) , T. pseudosemperi W. Horn, 1928 , and T. negrosicola Zettel & Pangantihon, 2017 . Therates monticola is very similar to T. semperi Schaum, 1860 in size but morphologically differs in having reduced punctation of the elytra, an entirely orange prothorax and mesoepisternum, an absent or small black circumscutellary mark, and large black medial marks on the elytra. Therates monticola has a black central mark of its elytron but it is short located near the apex ( Zettel and Pangantihon 2017). The aedeagus is moderately slender, and its dorsal side is not emarginated.

Remarks. This species was living with T. coracinus coracinus in open to partially shaded streams. Zettel and Pangantihon (2017) described this species recently, with the type locality in the Cordillera Central, Mountain Province Philippines.
