Bennett, Gordon M & O’Grady, Patrick M, 2011, Review of the native Hawaiian leafhopper genus Nesophrosyne (Hemiptera: Cicadellidae: Deltocephalinae) with description of eight new species associated with Broussaisia arguta (Hydrangeaceae), Zootaxa 2805, pp. 1-25 : 17

Nesophrosyne ogradyi Bennett sp. nov.

( Fig. 8 a–g)

Diagnosis. Length: male = 4.17mm, female = 5.65mm. A paler species than N. broussaisiai . Clavus entirely pale or with three spots, with a central round saddle mark flanked by lateral pale marks ( Fig. 8 a). Pronotum posterior 1/2 pale. Genitalia matching species group description ( Fig. 8 b–g). Endemic to East Maui, Haleakalā windward face.

Distribution. USA: Hawaiian Islands, Maui, Haleakalā windward face,> 910m, wet forest ( Fig. 3 )

Measurements. Body length: Male (n=10) = 4.17mm (4.00mm– 4.30mm); Female (n=10) = 5.65mm (5.50mm – 5.80mm). Genitalia (n=5): Pygofer = 0.57mm (0.56mm – 0.58mm); Style = 0.47mm (0.46mm – 0.48mm); Connective = 0.27mm (0.26mm – 0.28mm); Aedeagus lateral length = 0.31mm (0.30mm – 0.33mm); Aedeagus posterior height = 0.16mm (0.15mm – 0.17mm).

Host Plant: Broussaisia arguta . Coll. G.M. Bennett, P.M. O’Grady, K.M. Magnacca. Deposited in the BPBM, Honolulu, Hawai’i. Type #: 17305. Additional Material: 13 males, 17 females, Hawaiian Islands, East Maui, Makawao Forest Preserve, N20 o 48.638 W156 o 14.509, Elevation: 1310m, 31July2007, 6Aug2007, 6June2009. Host Plant: Broussaisia arguta . Coll. G.M. Bennett. Deposited in the BPBM, Honolulu, Hawai’i. 2 males, 2 females, Hawaiian, Islands, East Maui, Waikamoi Forest Reserve, N20 o 48.397 W156 o 15.295, Elevation: 1300m, 1June2009. Host Plant: Broussaisia arguta . Coll. G.M. Bennett. P.M. O’Grady, K.M. Magnacca. Deposited in the BPBM, Honolulu, Hawai’i. 5 males, Hawaiian Islands, Maui, Haleakalā , Pu’u O Kakai, TNCH, Waikamoi Preserve, N20o 48’00” W156o 14’44”, Elevation: 1500m, 16May2003. Host Plant: Broussaisia arguta . Coll: D.A. Polhemus. Deposited in D.A. Polhemus’s personal collection at the Smithsonian, Washington D.C.

Etymology. This species is named after Dr. Patrick O’Grady (Hawaiian Dipterologist) for his invaluable contributions to this project and for his positive scientific mentorship of G.M. Bennett.

Discussion. Nesophrosyne ogradyi represents a lighter form than N. broussaisiai . External morphology is nearly identical to N. kaupoi . Nesophrosyne kaupoi is distinguishable from N. ogradyi by its absent apical processes.

Partitioned Maximum Likelihood phylogeny of Nesophrosyne (Hemiptera: Cicadellidae) species reconstructed in RAxML-VI-HPC v 7.2.5 under a GTR + I + Γ likelihood model with 100 bootstrap partitions. Gene partitions are according to the mitochondrial genome (COII, 16 s) and nuclear genome (H 3, Wingless).
