CARPOSINA GAGNEORUM
sP. nOV.
, MEDEIROS & OBOYSKI (
FIGS 2
C, 3C, 4C)
Holotype:
United States: Hawaiian Islands: Molokai: Kamakou Preserve, Pepeopae Trail. 19.v.2004. ♂ (slide LB01♂). D Rubinoff
et al
. UHIM.
Paratype:
United States: Hawaiian Islands: Maui: Haleakala National Park, bog E of Kipahulu Val., 1859 m. 22–25.vi.1981. 1♀ 9 (slide LB60♀). WC Gagné. BPBM.
Diagnosis:
No other Hawaiian
Carposina
has a similar wing pattern: a dark brown medial band, abutted by a very light brown band just distal to it (
Fig. 2
C).
Description (
N
= 2) (
Fig. 2
C):
Wing expanse 17– 29 mm. Head grey-brown. Haustellum unscaled. Labial palpus approximately width of eye in male, nearly 3× width of eye in female, second segment brown, third segment dark brown. Antennae of male with long, fine cilia underneath. Thorax and tegula grey-brown to olive (abdomens of both specimens cleared and mounted on slides). Foreleg black. Midleg dark brown, spurs present. Hindleg brown, spurs present. Forewing ground colour grey-brown; a curving very dark brown medial band present, abutted by a very light brown band just distal to it, these bands consisting largely of raised scales; additional clusters of raised scales scattered proximally to the medial bands, these clusters more numerous and pronounced in the female specimen; fringe brown. Hindwing and fringe uniformly light pale brown.
Male genitalia (
Fig. 3
C):
Valvae long, narrow, tapering to an acute hooked apex. Uncus prominent, flanked by short dense setae. Arms of gnathos projecting upward sharply, tipped with outwardly projecting setae. Annelar lobes short, straight, approximately 0.5× length of valva. Saccus V-shaped. Process of sacculus broad, curving outward, apex two-pronged. Aedeagus (
in situ
,
Fig. 3
C) long, broad, widened distally, cornuti present along entire posterior section.
Female genitalia (
Fig. 3
C):
Papillae anales short. Apophyses thin and straight; posterior apophyses relatively long, 2× total length of anterior apophyses. Ductus bursae long, almost 2× length of posterior apopheses. Corpus bursae long, nearly length of ductus bursae; two large V-shaped signa present.
Distribution:
This species has been collected on the islands of Molokai and Maui, Hawaiian Islands.
Remarks:
The male genitalia of this species is similar to that of
C. graminicolor
(Walsingham)
and
C. crinifera
(Walsingham)
, also from the Hawaiian islands, but the wing pattern is extremely divergent, unlike any other Hawaiian
Carposina
. This species has not been collected since 2004, and attempts to amplify DNA were unsuccessful. New material is needed to place it within the phylogeny of
Carposina
. Larval biology and host plant unknown.
Etymology:
Carposina gagneorum
is named in honor of Betsy Gagné, and her late husband Wayne Gagné. Wayne collected the first specimen of this species, and was greatly admired and respected for his work in Hawaiian entomology and conservation. Likewise, Betsy, through her work at the State of Hawaii Division of Forestry and Wildlife for many years, is an ally to the Hawaiian insect fauna, and a dear friend of MJM and PTO.
