Gryllus bryanti Morse

Bahama Island Field Cricket

Figs 17, 22, Table 1

Although not known from the United States, this cricket is endemic to the Bahama Islands, which are less than 80 km away from the closest US location along the Florida coast. Since our earlier publication (Weissman et al. 2019), we have documented this cricket on a third island in the Bahamas: San Salvador, 24.122279° -74.45678°, 23-i-2019, 1♂, N. Lee, deposited CAS.

Recognition characters and song. Known only from 3 islands in the Bahamas. Body color as in Fig. 22. Song (Fig. 22) at 25°C typically with widely spaced single pulses delivered at 7–15/10 seconds at a pulse rate of 0.8– 2.1.

DNA. GBM05, from Andros Island, multilocus appears (Fig. 6, p. 28) to be one of several Gryllus near the base of a continental North American species group, distinct from the Afro-Eurasian G. bimaculatus and G. campestris Linnaeus. We interpret this result cautiously, however, as we lack DNA samples for other geographically nearby species G. jamaicensis Walker, G. mandevillus Otte & Perez-Gelabert, and G. bermudensis Caudell (probably most closely related to G. firmus [Kevan 1980]).
