Key to Nesophrosyne   species associated with Broussaisia arguta   on the Hawaiian Archipelago

Note: In most cases knowledge of host plant and collection locality (island and volcanic mountain) alone will differentiate species associated with Broussaisia arguta   .

1. Head obliquely triangulate ( Fig. 4 View FIGURE 4 a), with crown produced medially, bluntly pointed. Kaua’i........... N. heopoko   sp. nov.

- Head not triangulate, crown weakly produced ( Figs. 5–6 View FIGURE 5 View FIGURE 6 a & 8–9 a), rounded apically................................ 2

2. Gonopores subapical; aedeagus with apical processes produced distally, elongate 1 / 4 – 1 / 5 length of aedeagal arms ( Figs. 4 View FIGURE 4 & 5 View FIGURE 5 f)................................................................................................. 3

- Gonopores apical; apical processes of aedeagus extending from pore, short (~ 1 / 10 length of arm) or absent ( Figs. 8 View FIGURE 8 & 9 View FIGURE 9 f); Maui and Hawai’i................................................................ kanawao   species group,... 4

3. Dorsum with well-formed saddle mark, tapering to point anterad; posterior end subflat, appearing arrow-like pointing anterad; O’ahu ( Fig. 5 View FIGURE 5 )........................................................................ N. makaihe   sp. nov.

- Species without any pale markings on clavus; forewing veins prominent, darkly pigmented; Moloka’i ( Fig. 6 View FIGURE 6 )................................................................................................ N. magnaccai   sp. nov.

4. Dorsum with central pale saddle mark always present, usually with paired pale blotches anterad, appearing as three pale marks showing bilateral symmetry; palest forms with clavus entirely pale; Maui ( Fig. 7 View FIGURE 7 & 8 View FIGURE 8 )...... broussaisiai   species subgroup... 5

- Dorsum darker than above, usually without conspicuous saddle mark; claval veins discontinuously pale, extending short length from commissural line (appearing as two pale lines curving anterad) and with anterior intersection of claval veins pale, showing bilateral symmetry; palest forms with irregular, large pale blotches throughout clavus; Hawai’i Island ( Fig. 7 View FIGURE 7 & 9 View FIGURE 9 )................................................................................ aakokohaikea   species subgroup, 7 Note: The following are a closely related assemblage of Nesophrosyne   species most easily discerned by knowledge of collection locality:

5. West Maui; almost always with three pale marks ( Fig. 7 View FIGURE 7 a); darkest forms with only central oval saddle mark; apical process present, short 1 / 10 length of aedeagal arm................................................ N. broussaisiai   sp. nov.

- East Maui; characters not as above....................................................................... 6

6. Claval coloration ranging from three mark forms to entirely pale; apical process present, short 1 / 10 length of aedeagal arm

( Fig. 7 View FIGURE 7 & 8 View FIGURE 8 )............................................................................ N. ogradyi   sp. nov. - East Maui, Haleakalā   leeward face; species with claval coloration usually entirely pale; darker forms with dark bands across clavus, appearing disrupted; apical processes absent............................................ N. kaupoi   sp. nov.

7. Claval veins partially pale, extending from commissural line (appearing as two pale line curving anterad), with anterior intersection of claval veins pale, showing bilateral symmetry ( Fig. 7 View FIGURE 7 & 9 View FIGURE 9 ).......................... N. aakokohaikea   sp. nov.

- Clavus predominately pale, appearing irregularly shaped, connected with thin pale line across commissural line................................................................................................ N. kanawao   sp. nov.
