sp. nov.

Cimbrophlebia brooksi , sp. n.

( Figs. 4A View 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. 1 View FIGURE 1 A; 2A, B; 4A, C; 6A, C; 7A).

Description: holotype wing. As in diagnosis, Figs. 4A–B View FIGURE 4. A, B , and the following. Length ~ 31 mm long as preserved (incomplete, basal portion missing), 7 mm wide. Colouration as in Fig. 4A View FIGURE 4. A, B , above. Membrane rugose, except possibly in apical portion. Sc as for genus. Rs with five branches, Rs1, Rs2 both branched apicad pterostigmal region, Rs3+4 apparently not branched. M apparently with four branches, but region poorly preserved. Cu, Cu1, Cu2, 1A poorly, fragmentarily preserved. 2A: with four branches evident, most likely more branches. 3A: not preserved. Crossveins: none detected.

Paratype wing. As in diagnosis, Fig. 4 View FIGURE 4. A, B C–D, 5, and the following. Length ~ 38 mm as preserved, width not reliably measurable. Colouration as in Fig. 4 View FIGURE 4. A, B C, as in holotype, except more completely preserved (cf. Fig. 4A View FIGURE 4. A, B , C). Membrane rugose, except possibly in apical portion. Sc: Sc1 as for genus, Sc2 not preserved. R1 poorly preserved. Rs with four branches detected, region poorly preserved. Veins posteriad poorly, fragmentarily, or not preserved. Crossveins: none detected.

Type material. Holotype: SR 062005 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 B4131, June 2006. Paratype: SR990405, 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 B4131, October 1999.

Locality and age. Republic, Washington, USA, University of Washington / Burke Museum locality B4131; 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. 5 View 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.
