Republicopteron douseae new species

(Figs. 5–7)

Diagnosis. As for genus.

Description. Holotype tegmen. As in diagnosis and the following. Darkly infuscate throughout wherever preserved (darkness differing among specimens presumably by preservation) with some light spots between veins, crossveins as in P. maculata, but not as many or as distinct (perhaps preservation?). ScP with eight accessory branches preserved, surely more in missing basal region; no stridulatory file detected on CuPb.

Type specimens. Holotype. SR 00-04-06 part, no counterpart (Fig. 5), a well-preserved anterior basal-mid region of a tegmen, precostal region not preserved, with a fragmentary portion of a second wing closely associated and a beetle preserved between fragments; deposited in SR; collected by Cassie Douse at Republic locality B4131, May 1, 2000, labelled: Holotype, Republicopteron douseae Archibald, Gu, and Mathewes. Paratype 1: SRUI 09- 95 - 73, (Fig. 6), collected by Michael Santino at Republic exposure A0307, April 19, 2009; labelled Republicopteron douseae Archibald, Gu, and Mathewes Paratype 1. Paratype 2: SR 21-005-001, (Fig. 7), collected by Gregg Wilson at Republic exposure B4131, May 14, 2014; labelled Republicopteron douseae Archibald, Gu, and Mathewes Paratype 2.
