Phloeosinopsioides formosanus (Schedl) : Wood & Bright, 1992: 239. Xylechinus papuanus Schedl, 1969: 128 . (Synonymy: Wood 1985: 269). Phloeosinopsis triseriata Schedl, 1964a: 297 . Syn.n.

Taxonomy. I have compared the male holotype of P.formosanus (NMW as Xylechinus formosanus ) from Taiwan with the female holotype of P.triseriata (NMW) from Sumba I., and specimens from Taiwan, Sabah and Sulawesi (AFW, RAB). I have also examined a paratype of X.papuanus (NMW), and two specimens from Papua New Guinea identified by S. L. Wood as P.triseriatus (SLW). Only a single species is represented. Phloeosinopsis triseriata Schedl is therefore synonymised with P.formosanus (Schedl) .

Distribution. Indonesia (Sulawesi, Sumba), East Malaysia (Sabah), Papua New Guinea, Philippines, Taiwan. This is the only species of Phloeosinopsioides with a wide distribution. It has presumably spread northwards and westwards from what seems to be the centre of origin of the genus in New Guinea and Australia.

New records. INDONESIA, Sulawesi Utara, Dumoga-Bone N.P., ‘Hog’s Back’ camp, 492 m, lowland forest, at light, ix.1985 (2) (RAB); Toraut, 234 m, multistory evergreen forest, at light, 17.viii.1985 (1) (J.Huijbregts) (NMNH); MALAYSIA, Borneo [Sabah], bei Keningau, 50 yrs, Melanolepis sp., 18–21.ii.2001 (45); Saraca dentata , 21.ii.2001 (13) (A.Floren) (AFW, RAB).

Biology. The specimens from Papua New Guinea determined by S. L. Wood were taken from an unidentified liana. The specimens collected by A. Floren were obtained by canopy fogging of the tree species mentioned, and may or may not have been breeding in these trees.
