Described from ten specimens: ‘type ♂ (26430) and nine ‘paratypes’ from Kauai, Oahu, Molokai and Lanai. Given the manner in which the descriptions were written, Walsingham likely considered them as the holotype and paratypes, as indicated on their specimen labels. However, because a holotype was not specified in the description, the so-labeled types and paratypes are to be considered syntypes under Article 73.2 of the Code (ICZN 1999), and any one of them is thus eligible for designation as lectotype under Article 74 of the Code (ICZN 1999). We could not find ‘type ♂ (26430)’ from 2000 ft., Lanai, xii.1894 and six syntypes: 1 (sex unknown), Halemanu, 4000 ft, Kauai, v.1895; 1 (sex unknown), Waianae Mts., 2000 ft., iv.1892, beaten from “Lefua” (Metrosideros polymorpha ?); 1 (sex unknown), Mts., near Honolulu, 2000 ft., 25.x.1892; 1 (sex unknown), Kalae, 1500 ft., v.1893; 1 (sex unknown), Mts., about 4000 ft., 9.vi.1893; 1 (sex unknown), 3000 ft., Lanai, ii.1894. Zimmerman (1978a: 701, fig. 466) provided the last photograph for the ‘holotype’ (=type ♂ (26430)) in the NHMUK. The current curator of NHMUK, D.C. Lees informed us that the ‘holotype’ of P. splendida is not stored in the designated location of the NHMUK. We selected a lectotype from three syntypes (Fig. 9A), and the remaining syntypes are paralectotypes. Additional material. 28 (14 ♂, 11 ♀, 3 sex unknown).

Diagnosis. This species and P. lama sp. n. have a brownish ocherous basal oblique fascia on forewing (Figs. 9A, B, 73B, C). Genital features very similar to those of P. basalis and P. lama, but distinguished by a rather slender dorsal process of valva in male. Kauai specimens (CJ488, male unknown) on Syzygium sp. have similar forewing pattern (Fig. 26D, E) and female genitalia, but the Oahu specimen (CJ312, thorax sacrificed for molecular analysis) have thickened dorsal process with slightly curved dorsal side (Fig. 41K) and slender saccus (Fig. 42J). Redescription: Adult (Figs. 9A, B, 26D, E, 73B, C). Wingspan 8–9 mm in type series; forewing length 4 mm in holotype, 3.9 mm in paratype. Head dark brown; frons white; maxillary palpus reduced; labial palpus white, externally fuscous at apical portion. Antenna grayish fuscous. Thorax leaden gray. Forewing shining, pale leaden gray with dark brownish ocherous patches enclosing gray fascia: bp from near base of costal fold to dorsal 1/4; tf from costal 1/3 to dorsal 1/2, tp after the middle to apical portion, distinctly narrowing in the dorsum, containing two short, shining, steel gray costal spot; apical portion with large jet-black terminal patch from tornus to apex, containing two upright steel-gray streaks near its opposite extremities; a single bright silvery dot in its middle; a very narrow ocherous line along the base of tornus; cilia shiny, leaden gray with a black fringe line; two white costal lines, long one extend apex; terminal cilia often black. Hindwing coppery brown; cilia tawny. Abdomen tawny brown, silver below. Legs grayish fuscous, with white spots on tarsal joints and at distal end of tibiae; spurs white. Male genitalia (Figs. 41J, K, 42I, J, 43I, J, 64G, I) (n=3). Capsule 830 µm. Tegumen same length as valva and rather wide; valva 490 µm long, similar to P. basalis except dorsal process rather slender (Fig. 41J). Saccus broad and straight (Fig. 42I). Phallus 660 µm long, sinuous in lateral view; cornuti large and well developed apically (Fig. 43I). Female genitalia (Fig. 56K) (n=4). 1400 µm long. Lamella antevaginalis 200 µm in length. Corpus bursae 800 µm long. Similar in the appearance to P. basalis. Distribution. Kauai, Oahu, Molokai, Lanai (Walsingham 1907), and Hawaii (Big Island) (Zimmerman 1978a). Host plants. Myrtaceae: Metrosideros polymorpha Gaudich. (Walsingham, 1907), Syzygium sp.: new record. Biology. (Figs. 66C, D, 82). Swezey (1913b: 223) reported the “taco” like cocoon and mature larval habit, which are similar to that of P. basalis. The biology is poorly studied, but it is presumably similar to that of P. basalis. In general, larvae form slender linear mine on the adaxial leaf surface (Fig. 82E), which gradually expands as lavae feed and grow (Fig. 82A). One or two mines per leaf. We often observed the fallen mined leaves under the host plant (Fig. 66C, D) with late instar larvae in the mine and/or pupae in a taco cocoon on or near the leaf. Parasitoids. (Fig. 101G, H). Bethylidae: Sierola philodoriae Fullaway, 1920; Eulophidae: Pauahiana metallica Yoshimoto, 1965 (Zimmerman 1978a). Remarks. We identified two adult moths (Coll ID CJ-049 / GenBank accession no. ID KT982402 and CJ-105 / KT982410) as P. splendida, based on the presence of a brown basal oblique fascia on forewing and host plant, from which whole bodies were sacrificed for molecular analysis (Johns et al. 2016).
