Nesophrosyne kanawao Bennett sp. nov.

(Fig. 7 d)

Diagnosis. Length: male = 4.19mm, female = 5.45mm. Dark species. Clavus predominately and irregularly pale, pigmentation bleeding throughout clavus from claval veins; costal cells and proximal cells partly hyaline (Fig. 7 d). Endemic to Kohala Mountain Range, Hawai’i Island.

Distribution. USA: Hawaiian Islands, Hawai’i, North West Kohala Mountain Range, 1520m, wet forest (Fig. 3).

Measurements. Body length (n=4): Male (n=4) = 4.19mm (4.17mm – 4.21mm); Female (n= 4) = 5.45mm (5.3mm – 5.6mm). Genitalia (n=4): Pygofer = 0.56mm (0.55mm – 0.57mm); Style = 0.48mm (0.48mm – 0.49mm); Connective = 0.27mm (0.26mm – 0.28mm); Aedeagus lateral length = 0.36mm (0.34mm – 0.37mm); Aedeagus posterior height = 0.22mm (0.21mm – 0.23mm).

Material examined. Type Material: Holotype: 1 male, Hawaiian Islands, Hawai’i, Kohala Mountains, Kawaihae Oka, Pu'u O Umi Natural Area Reserve, Elevation: 1520m, N20 o 0 4.947 W155 o 45.128, 5October2006. Host Plant: Broussaisia arguta . Coll. G.M. Bennett. Deposited in the BPBM, Honolulu, Hawai’i. Type #: 17307. Additional Material: 5 males, 4 females, same as holotype. Deposited in the BPBM, Honolulu, Hawai’i.

Etymology. The kanawao species group is named after the Hawaiian word for Broussaisia arguta for the association of its constituent species with this plant species.

Discussion. There is considerable overlap in the external coloration between N. kanawao and N. aakokohaikea, despite relatively large COII percent divergence (COII % divergence avg. = 9.23%). Nesophrosyne kanawao occurs in the Kohala Range, which is higher in elevation than the described N. aakokohaikea . Similar to species in the broussaisiai species subgroup, it is unknown if adaptation to elevational gradients or geographic limits to dispersal contribute to speciation in this subgroup. Sampling from across Hawai’i Island on different volcanoes and at varying elevations would help elucidate this question.
