Myrsidea lightae Price, Johnson and Dalgleish, 2008

Myrsidea lightae Price, Johnson and Dalgleish, 2008: 2 , Figs. 1–4 . Type host: Saltator maximus (Müller) —Buff-throated Saltator

Material studied. 2 males ex Saltator maximus , COSTA RICA: Hitoy Cerere BR, Provincia Limón (9˚40’N, 85˚05’W), 21 August 2004, Literak leg. (O.Sychra CR62). Deposited in INBio.

Remarks. As we predicted in our previous paper ( Sychra et al. 2007) Myrsidea lice from this host represented a unique species that was subsequently described as new by Price et al. (2008). Since our specimens collected from the type host differ a little from the original description of M. lightae , we mention these differences here [setal counts and dimensions mentioned by Price et al. (2008) are in parentheses]:

Male (n = 2). Mean length of head seta 10, 0.055 (n=3); seta 11, 0.107 (n=3); ratio10/11, 0.52. Metanotal margin with 11–13 (13–19) setae. Tergal setae: I with a continuous row of setae, all other tergites with a well-defined median gap in the rows of setae; III, 17–22 (18–22); IV, 17–22 (16–20); VI, 17–22 (16–20); VII, 17–22 (15–20). Sternal setae: II 7–8 (9–14) anterior; IV, 38 (39–46); VI, 24–28 (36–41); without medioanterior setae. Dimensions: HL, 0.28–0.31 (0.31–0.33); GL, 0.49–0.50 (0.46–0.49); GW, 0.13; GSL, 0.09.
