sp. nov.

Myrsidea seversoni Price, Hellenthal and Dalgleish , new species ( Fig. 7 View FIGURES 1 – 8. 1 – 2 )

Type host. Tyrannus verticalis Say , Western Kingbird.

Female. Dorsal thorax and abdomen as in Fig. 7 View FIGURES 1 – 8. 1 – 2 . Metanotum with 10, much less often 9 or 11, marginal setae. Tergites II–IV with slight medioposterior convexity. Tergal setae: I, 10–12; II–V, 14–20; VI, 15–17; VII, 9–13; VIII, 8, rarely 9. Postspiracular setae very long and of similar length on I–VIII. Sternal setae: II, each aster with 4–5 setae, 22– 32 other setae; III, 22–27; IV, 51–60; V, 56–68; VI, 43–49; VII, 15–20; VIII–IX of subgenital plate, 23–29. Anus with 35–42 setae in each fringe. Dimensions: TW, 0.54–0.56; HL, 0.36–0.39; PW, 0.33–0.35; PSL, 0.13–0.14; MW, 0.51–0.53; MSL, 0.16–0.18; AWIV, 0.67–0.72; ANW, 0.24–0.26; TL, 1.78–1.87.

Male. Unavailable.

Type material. Holotype female ( OSU), ex T. verticalis, Stillwater , Oklahoma, U.S.A., 5 Jun 1948, K. C. Emerson. Paratypes ( OSU, TNHM): 19 females, same data as holotype.

Remarks. Though we have only females available for this description, the uniformly very long postspiracular setae on I–VIII, in combination with the number of tergal and sternal setae and the large dimensions, readily separate Myrsidea seversoni from others of this species group.

Etymology. This species is named for David W. Severson, University of Notre Dame, in recognition of his many contributions to our understanding of the role of mosquitoes in disease transmission.
