Ex Glyphorynchus spirurus : 1♀ , Barbilla National Park , Provincia Limón , Costa Rica ( 09°59'N , 85°27'W ), 3 September 2004 , I. Literak , M. Capek & M. Havlicek ( INBIO—O . Sychra CR 10). Remarks. Here we confirm that a female described as “ Myrsidea sp. 2” by Sychra et al. (2007) is conspecific with M. dalgleishi originally described from G. spirurus from a different location in Costa Rica . Our specimen differ from the original description of M. dalgleishi by setal counts and dimensions, as follows [data from Valim et al. (2011) are in parentheses]: Female (n = 1). Length of dhs 10, 0.065 (0.03); dhs 11, 0.102 (0.09); ratio dhs 10/11, 0.64 (0.33). Gula with 5– 6 (4–5) setae on each side. Tergal setae: II, 12 (8–10); IV, 12 (9–11); VI, 7 (10–11); VII, 4 (7–8); VIII, 4 (5–6). Sternal setae: IV, 26 (22–24); VI, 23 (19–21).
