Neocybaeina burnetti Bennett spec. nov.

Figs 40–42 View FIGURES 36–42 , 84 View FIGURES 84–86

Type material. U.S.A.: Oregon: Holotype female. Curry County, 12 miles northeast of Gold Beach , 30.ix.1959, V.D. Roth ( CAS) . Paratypes. Curry, 3♀, Carpenterville , 31(sic). ix.1959, V.D. Roth ( CAS) ; 1♀, 12 mi. N of Gold Beach , 1.x.1959, V.D. Roth ( AMNH) .

Etymology. The specific name is a patronym honouring the late blues musician, lyricist, and band leader Chester “Howling Wolf” Burnett.

Diagnosis. The male of N. burnetti spec. nov. is unknown. The females of N. burnetti spec. nov. and N. xantha comb. nov. can be distinguished by, in the former, the strongly arched atrium ( Figs 40–41 View FIGURES 36–42 ), the copulatory ducts proceeding posterolaterally from the atrium ( Figs 41–42 View FIGURES 36–42 ), and the longitudinal orientation of the spermathecal stalks ( Fig. 42 View FIGURES 36–42 ). In the female of N. xantha comb. nov. the atrium is weakly convex ( Figs 36, 38 View FIGURES 36–42 ) or represented by a pair of tiny, widely separated openings ( Fig. 39 View FIGURES 36–42 ), the copulatory ducts proceed anterodorsally from the atrium ( Figs 38–39 View FIGURES 36–42 ), and the spermathecal stalks are transversely oriented ( Figs 37, 39 View FIGURES 36–42 ).

Description. As in diagnosis and description of the genus and the diagnosis of this species.Additional descriptive characters presented here. Abdomen patterned, legs unbanded.

Male: Unknown.

Female: (n=5). Epigyne ( Fig. 40 View FIGURES 36–42 ) with a single anteriorly located atrial opening. Vulva ( Figs 41–42 View FIGURES 36–42 ) with very short copulatory ducts with posterior-most portion heavily sclerotized and visible ventrally through epigynal integument as two darkened areas ( Fig. 40 View FIGURES 36–42 ); spermathecal heads at anterior margin of spermathecae, undifferentiated from spermathecal stalks; stalks short; Bennett’s glands large, conspicuous; spermathecal bases usually visible through epigynal integument ( Fig. 40 View FIGURES 36–42 ) with short, slightly constricted anterior region adjacent to Bennett’s glands and elongate, oval, bulbous posterior region; fertilization ducts attached to ventral surface of posterior region of bases.

Measurements (n=3). CL 1.68, 1.98, 2.00; CW 1.25, 1.45, 1.48; SL 0.95, 1.08, 1.13; SW 0.87, 0.99, 1.03. Holotype listed second.

Distribution and natural history. ( Fig. 84 View FIGURES 84–86 ). Neocybaeina burnetti spec. nov. is known only from a small area of Curry County in coastal southwestern Oregon, U.S.A. The conservation status of this species is unknown: all specimens were collected during a 2–3 day period in late September and early October 1959 and apparently no specimens have been collected subsequently.
