CARPOSINA URBANAE sP. nOV., MEDEIROS & OBOYSKI ( FIGS 2 D, 3D, 4D)

Holotype: United States: Hawaiian Islands: Kauai: Kokee St Park, Pihea Tr, 22.149, −159625. 21.vii.2014. ♂ (slide 14A94♂). MJ Medeiros & AX Nguyen. BPBM.

Paratypes: United States: Hawaiian Islands: Kauai: Na Pali – Kona FR, Alakai Swamp at Junction of Pihea Trail. 18.v.2005 & 23.vii.2006. 1♂, 1♀ (slide LB61♀). D Rubinoff. UHIM.

Diagnosis: Carposina urbanae has a unique wing pattern in comparison with all other Hawaiian Carposina : an orange-brown medial band running from the costa to middle of wing, diagonally toward the tornus ( Fig. 2 D).

Description (N = 3) ( Fig. 2 D): Wing expanse 17– 20 mm. Head light brown. Haustellum unscaled. Labial palpus longer nearly 2× width of eye in male, over 2× width of eye in female, dark brown near base of second segment, transitioning to lighter brown by apex of third segment. Antennae of male with long, fine cilia underneath. Thorax, tegula and abdomen light brown. Foreleg and midleg very dark brown, with rings of lighter scales near joints of tarsi; spurs present in midleg. Hindleg similar but somewhat lighter in colour, spurs present. Forewing ground colour very light brown; orangebrown medial band running from costa to middle of wing, diagonally toward tornus, with several clusters of raised scales; posterior half of wing darker in colour than anterior half; orange-brown basal spot present; orange and black spots present along costal margin; fringe grey. Hindwing and fringe uniformly light brown.

Male genitalia ( Fig. 3 D): Valvae long, somewhat broad, tapering to an acute apex. Uncus nearly absent. Annelar lobes projecting caudal, straight, less than 0.5× length of valva. Arms of gnathos long, projecting sharply upward, topped with short setae. Process of sacculus broad, tipped with two short lobes. Saccus V-shaped. Aedeagus long, slender, widened distally, cornuti present at apex.

Female genitalia ( Fig. 4 D): Papillae anales short. Apophyses thin and straight; posterior apophyses relatively long, approximately 1.5× length of anterior apophyses. Ductus bursae long, approximately 1.5× length of posterior apophyses. Corpus bursae oval, short, about 0.5× length of anterior apophyses; signum absent.

Distribution: This species has been collected only from near the summit of the island of Kauai, Hawaiian Islands.

Remarks: The male genitalia of this species is similar to that of C. ferruginea (Walsingham) and Zimmerman’s ‘new species 2’ (Zimmerman, 1978, p. 830), also from the Hawaiian Islands, but the wing pattern is extremely divergent, unlike any other Hawaiian Carposina . Larval biology and host plant unknown.

Etymology: Carposina urbanae is named in honour of the Urban School of San Francisco, where MJM has been a science teacher for 5 years, and many of his Urban Advanced Studies Genetics students performed PCRs used in this study. Urban has support- ed MJM’s research programme in multiple ways. Lastly, Urban has shown a commitment to entomology, with the formation of a new class, Entomology: Bugs & Biodiversity, which provides an education in general entomology to high school students.
