TYPES: Male holotype and female paratype from Hawai’i Co.: Honokahau (19.680667°, -156.023544°), Sep. 06, 1957, A. Nadler, deposited in AMNH, PBI_OON 50036 ; same data, 1 male and 3 female paratypes deposited in AMNH, PBI_OON 38004 ; Kaua’i Co.: Kahili Mountain , 5 mi N Koloa (21.96196°, -159.47770°), Jan. 11, 1998, J., E. Berry, 1 male paratype deposited in JAB, PBI_OON 42714 ; Maui Co.: Kahului, Maui , Sep. 17, 1957, A. Nadler, 1 female paratype deposited in AMNH, PBI_OON 38006 .

ETYMOLOGY: The specific name is a noun in apposition, after Kamehameha I, first king of Hawai’i.

DIAGNOSIS: Males can be distinguished from those of the other species by the PME placed on a protuberance (fig. 10B), a posterior eye row procurved in front view (fig. 10D), a higher clypeus with long, needlelike setae directed upward (fig. 10B, C), a larger copulatory bulb and the subbasal insertion of the patella-tibia joint on the palp (fig. 16D–F). Females can be distinguished by having small, nearly contiguous external pockets on the epigastric region, and a long anterior receptaculum (figs. 18D, 19D, 21D, F).

MALE (PBI_OON 38004): CEPHALOTHO- RAX: Carapace orange, with net-shaped pattern, broadly round in dorsal view (fig. 10A–D). Clypeus high. Posterior eye row procurved in front view (fig. 10D), PME placed on protuberance (fig. 10B), touching for less than half their length. Sternum as long as wide, with net-shaped pattern. Labium rectangular. ABDOMEN: Dorsum soft portions dark purple, with gray netlike pattern. LEGS: Yellow, patella plus tibia I longer than carapace. GENITALIA (fig. 16D–F, 20I–K): Palp proximal segments yellow, patella-tibia joint subbasal, tibia with one brown band at middle; bulb yellow, large, spherical; embolus dark, sperm duct with only two loops (fig. 20I).

FEMALE (PBI_OON 38004): Total length 1.69 (fig. 10E–G). CEPHALOTHORAX: Posterior eye row slightly recurved from font; PME not placed on protuberance, touching throughout most of their length. Sternum longer than wide. Labium elongated, hexagonal. LEGS: Patella plus tibia I shorter than carapace, femora, patellae, tibiae with purple pigment. GENITALIA (figs. 18D, 19D, 21D, F): Epigastric region with small external pockets, internal pockets absent; anterior receptaculum long, twisted ventrally; posterior receptaculum apparently absent, posterior apodeme divided, formed two parallel plates.

DISTRIBUTION: Known only from the Hawaiian archipilego, Kaua’i and Maui islands (map 1).

OTHER MATERIAL EXAMINED: None.
