General features — Dorsal and ventral shield present; dorsal shield complete, with colour pattern as photographed in Figure 20L . Dorsal portion of gnathosomal bay bluntly pointed and projecting well forward; one row of idiosoma pores on each side between Cx-II and Cx-III ( Figure 13A ). Genital field with three pairs of acetabula. Palp: two long setae on medial surface of P2 inserted near middle of segment, antagonistic bristle of P4 long and whip-like, P5 inserted dorsally at distal end of P4 ( Figure 13D ). Gnathosomal rostrum wide, distally truncated and ending in a wide, flat-arched, posteriorly slightly tapering gnathosoma ( Figure 13B ), its posterior margin without a central indentation ( Figures 21 G-H). Male – Dorsal shield long 638 and 606 wide; ventral shield 950 long and 900 wide. Genital field 226 long and 244 wide, gonopore 209 long and 63 wide. Ejaculatory complex L 309. Palp: dorsal length/height, dorsal length/height ratio: P1, 16/53, 0.29; P2, 78/59, 1.32; P3, 49/56, 0.88; P4, 78/50(basal), 1.56; P5, 58/26, 2.2. Gnathosoma 228 long and 97 wide. Chelicera 275 long. Dorsal length of I-leg: 69, 72, 113, 153, 153, 203; dorsal length of IV-leg: 131, 150, 150, 194, 209, 213; IV-leg-3 and -4 without a row of enlarged setae on dorsal surface characteristic for Geayela . Swimming setae: II-leg-4, 4; II-leg-5, 3-4; III-leg-3, 5; III-leg-4, 13-14; III-leg-5, 10-11; IV-leg-3, 9; IV-leg-4, 13; IV-leg-5, 11. Remarks — Geayia latirostris was originally described based on a female from Igarapé São Benedito in the Amazon region of Brazil ( Viets 1954b ). Therefore, this is the first description of the male.
