Therates coracinus coracinus Erichson, 1834 View in CoL

Material examined. PHILIPPINES, Apayao Province, Municipality of Calanasan, 3♂♂, 3♀♀ Brgy. Tanglagan [18.3792°N, 120.9571°E], 1♂, 2♀♀ Brgy. Parina [18.4301°N, 120.9699°E] IX-X.2018, coll. R.J. T. Villanueva ( Fig. 5A); UMCRC 010143, UMCRC 010144, UMCRC 010145, UMCRC 010146, UMCRC 010147, UMCRC 010148.

Identification. Most similar to this species are T. fasciatus pseudolatrellei W. Horn, 1928 and T. fulvipennis

everetii Bates, 1878 in having a long labrum, the galea of the maxilla reduced to one segment, a highly reduced 4th tarsal segment. However, Therates coracinus coracinus is easily recognized by its shiny black upperparts ( Wiesner 1988), whereas the other two species have either an orange-and-black combination or an entirely orange elytron. In size, it is similar with T. fulvipennis fulvipennis W. Horn, 1928 .

Endemism and distribution. An Oriental species. Philippines (Luzon, Mindoro, Romblon, Samar, Leyte, Panay, Negros, Palawan, Balabac, Mindanao), Indonesia (Sulawesi, Talaud), Moluccas (Halmahera, Bacan) ( Cabras et al. 2016b; Cassola 2000).

Remarks. This species was frequently encountered in a cold, well-shaded to partly shaded stream. Several individuals were seen flying and perching on twigs, logs, and leaves near the stream, and they sometimes perched on exposed boulders along the stream. They were very abundant in areas with no or little human activity. Cassola (2000) regarded this to be a widespread Philippine endemic species (with two subspecies). However, Cabras et al. (2016b) included some eastern islands of Indonesia as part of the range of the species. Additional study of the many species of Therates in the Philippines is needed to determine their taxonomic status.
