Cimbrophlebia brooksi  , sp. n.

( Figs. 4 AView FIGURE 4. A, B –D, 5)

Diagnosis. Wing distinguished from those of other Cimbrophlebia  species by the following: 1), Shape: narrow, length about five times width separates it from wider wings of C. leahyi  , C. westae  , C. flabelliformis  [length about four times width], ( C. bittaciformis  similarly slender); 2), Colouration: distinct from that of C. flabelliformis  , C. westae  , C. bittaciformis  , C. leahyi  (see descriptions, C. flabelliformis  remarks, Figs. 1View FIGURE 1 A; 2 A, B; 4 A, C; 6 A, C; 7 A).

Description: holotype wing. As in diagnosis, Figs. 4 A –BView FIGURE 4. A, B, and the following. Length ~ 31 mm long as preserved (incomplete, basal portion missing), 7 mm wide. Colouration as in Fig. 4 AView FIGURE 4. A, B, above. Membrane rugose, except possibly in apical portion. Sc as for genus. Rs with five branches, Rs 1, Rs 2 both branched apicad pterostigmal region, Rs 3 + 4 apparently not branched. M apparently with four branches, but region poorly preserved. Cu, Cu 1, Cu 2, 1 A poorly, fragmentarily preserved. 2 A: with four branches evident, most likely more branches. 3 A: not preserved. Crossveins: none detected.

Paratype wing. As in diagnosis, Fig. 4View FIGURE 4. A, B C –D, 5, and the following. Length ~ 38 mm as preserved, width not reliably measurable. Colouration as in Fig. 4View FIGURE 4. A, B C, as in holotype, except more completely preserved (cf. Fig. 4 AView FIGURE 4. A, B, C). Membrane rugose, except possibly in apical portion. Sc: Sc 1 as for genus, Sc 2 not preserved. R 1 poorly preserved. Rs with four branches detected, region poorly preserved. Veins posteriad poorly, fragmentarily, or not preserved. Crossveins: none detected.

Type material. Holotype: SR 062005View Materials A, B, part and counterpart. A well-preserved fore- or hind wing, missing basal portions; housed at SR; labelled: Holotype Cimbrophlebia brooksi, Archibald, 2009  . Collected by Karl Volkman at Republic locality B 4131, June 2006. Paratype: SR 990405View Materials, part only. A mostly wellpreserved fore- or hind wing, but posterior region indistinct; housed at SR; labelled: Paratype Cimbrophlebia brooksi, Archibald, 2009  . Collected by Caleb Brooks at Republic locality B 4131, October 1999.

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 Caleb Brooks, the collector of the paratype specimen, recognizing his generosity in this donation to SR.

Remarks. The rugose membrane of much of the wings of C. brooksi  ( Fig. 5View FIGURE 5) is not mentioned as present in C. bittaciformis  by Willmann (1977) nor seen in his figures, nor on the wings of C. sp. A or C. flabelliformis  . It is found in C. leahyi  , and C. westae  , however.
