Cimbrophlebia westae  , sp. n.

( Fig. 6View FIGURE 6)

Diagnosis. Wing distinguished from those of other Cimbrophlebia  species by the following: 1), Shape: length about four times width separates it from C. brooksi  [distinctly narrower: length about five times width], C. bittaciformis  [similarly slender (see C. flabelliformis  remarks)], ( C. leahyi  , C. westae  length also about four times width); 2), Colouration: distinct from that of C. flabelliformis  , C. brooksi  , C. leahyi  , C. bittaciformis  (see C. flabelliformis  remarks); closest to that of C. leahyi  , further differentiated from C. leahyi  by distinctly round / oval light spots [ C. leahyi  : differing position, sizes of more irregularly shaped light spots (see descriptions, C. flabelliformis  remarks, Figs. 1View FIGURE 1 A; 2 A, B; 4 A, C; 6 A, C; 7 A).

Description: holotype wing. Wing as in diagnosis, Fig. 6View FIGURE 6, and the following. Length ~ 25 mm, width ~ 6 mm. Colouration (basal third colouration poorly preserved) as in diagnosis. Membrane rugose, except in apical quarter, anal region. Sc, R 1 generalized for genus. Rs with five branches. M with three branches evident, region partly not preserved; Cu 1, Cu 2, 1 A generalized for genus; 2 A with five branches known (only apical portion clearly preserved); 3 A region not preserved. Crossveins: few detected as preserved; one r 1 -rs, one m-m, one m-cu 1.

Type material. Specimen SRUI 0 99600, part only. A mostly well-preserved wing missing part of the apical posterior portion, with basal portion of 2 A region obscured, and basal third colouration obscured by mineral staining. Collected by Joanne West, April 19, 2009 at Republic. Housed at SR. Locality and age. Republic, Washington, USA, University of Washington / Burke Museum locality B 4131; Early Eocene.

Etymology. The specific epithet is a patronym formed from the surname of Joanne West, the collector of the holotype specimen, recognizing her generosity in this donation to SR and valued participation in a collecting project on behalf of the author’s research.
