Philodoria kolea Kobayashi, Johns & Kawahara, 2018: 132–137 , 3, 5K, L, 7A–D, I, 12, 13, 14D

Type locality. Hawaii Volcanoes National Park ( Big Island ).

Type material. Holotype ♂, Hawaii Volcanoes National Park, Hawaii ( Big Island ), 25.iv.2016, A. Kawakita leg., host: Myrsine lessertiana (understory shrub), Gen-Bank accession no. MF804825 , IO-322, SK 851 in BPBM. The type series was mounted from emerged adult moths.

Paratypes, in BPBM: 1♀ , Kaumana Trail, Hilo, Hawaii ( Big Island ), 28.iv.2016, em., C.L. - Vaamonde & C. Doorenweerd leg., host: Myrsine sp., 20.iv.2016 (Cocoon), HILO016, SK 634♀ . 1♀, Thurston lava tube (Nahuku), Hawaii Volcanoes National Park , Hawaii Is. , 13.v.2016, em., S. Kobayashi leg., host: Myrsine lessertiana , 25.iv.2016 (larva), SKH-05-1, SK 632♀ ; 1♀, same locality and data as holotype, IO-323, SK852; 2♀ , same locality as holotype, 2& 24.v.2016, em., C.L. - Vaamonde & C. Doorenweerd leg., host: Myrsine lessertiana , 22.iv.2016 (larva), HILO020/SKH-15, SK 630♀, 631♀ .

Diagnosis. Among Philodoria species having similar fuscous forewing coloration (i.e., P. epibathra (Walsingham) , P. nigrella (Walsingham) P. pipturiana Swezey , and P. wilkesiella Swezey (See Zimmerman 1978a)) , P. kolea is distinguished by the white and bronze color bands on the forewing ( Fig. 7F ). The forewing pattern and genitalia are similar to those of other Myrsine mining species, P. auromagnifica and P. succedanea , but P. kolea completely lacks the orange markings ( Fig. 7F ).

Adult ( Fig. 7F , 34B, C , 35 ). Wingspan 6.7 mm in holotype, 6.6, 8.5 mm in paratypes. Male genitalia ( Figs. 41D , 42D , 43D ) and Female genitalia ( Fig. 56F ). See also Kobayashi et al. (2018).

Distribution. Hawaii (Big Island) ( Kobayashi et al. 2018). Host plants. Primulaceae : Myrsine lessertiana A. DC. ( Kobayashi et al. 2018) .

Biology. ( Figs. 79I–K ). Kobayashi et al. (2018: 136–137, figs. 12, 13, 14D) reported the leaf mine and pupal cocoon.
