Orchidophilus peregrinator Buchanan

Acythopeus sp., Swezey (1934).

Orchidophilus peregrinator Buchanan, 1935: 46 . Holotype female, labelled “Manoa Valley/ Oahu 3-1-1928 ”, “Atherton’s/ Orchid House”, “ O. H. Swezey/ Collector”, ” TYPE USNM/ 50424”, “ Orchidophilus / peregrinator / Buchanan/ TYPE ” (USNM). Paratypes 9 [supposedly 10, but 2 are actually parts of 1 specimen] (BPBM, 3, USNM, 6). Swezey (1945), Carter (1945), Holdaway (1946), Pritchard (1959), Voss (1961), O’Brien & Wibmer (1982), Morimoto (1994), Hirao et al. (2001).

Distribution. Native to Indonesia and the Philippines; probably introduced and then established in the Solomon Islands; adventive but not established in the United States (incl. Hawaii).

Plant associations. Orchidaceae , Epidendroideae : Dendrobium nobile , Grammatophyllum multiflorum , Phalaenopsis amabilis , P. s c h i l l e r i a n a, Renanthera sp., Vanda coerulea , V. luzonica , V. t e re s, Vanda x Miss Joaquim.

Records. Indonesia: Celebes [Sulawesi], Minnihassa area, 1953 (USNM, 3). Philippines: Hirao et al. (2001). Solomon Islands: Guadalcanal, 1950 [female, record needs confirmation] (USNM, 1). United States: Washington, DC, 1923, interception, origin Philippines (USNM, 1 PT); San Francisco, CA, 1936, 1938, interceptions, origin Philippines (USNM, 2), ditto, 1937, origin Japan (USNM, 1); Hawaii, Oahu, Manoa Valley, greenhouse, 1928 (BPBM, 3 PT; USNM, HT+3 PT); Honolulu, 1930, 1932, 1933, 1935, 1944, 1946, 1947, interceptions, 2 with origin Philippines (BPBM, 8; USNM, 3+2 PT).

Notes. To my knowledge, this species has not been intercepted since the 1940s. Field collections were made more recently in Sulawesi and probably the Solomon Islands, but these specimens were not recognized as O. peregrinator . For reliable identification, male specimens should be examined for possession of the square median projection on the posterior edge of the last ventrite ( Fig. 8 ).
