Type material. Holotype: ♂ from Estero el Salado, Puerto Vallarta , Jalisco, Mexico, 20.662 to 20.667°N, 105.240 to 105.241°W, 2014, W.P. Maddison ( WPM#14-002, JAL14-8565), deposited in UBC-SEM GoogleMaps   . Paratype: 1 ♀ from Chachalaca Trail , Estación de Biología Chamela, Jalisco, Mexico, 19.4966°N, 105.0404 to 105.0426°W, 2014, W.P. Maddison ( WPM#14-017, JAL14-9187), deposited in UBC-SEM GoogleMaps   .

Etymology. The epithet is to be treated as a Latin adjective and refers to the country where specimens listed herein were collected.

Additional material examined. MEXICO: Jalisco (Estación de Biología Chamela, Viveros , 19.499°N, 105.043°W): 1 ♀, 28.II–1.III.2014, W.P. Maddison ( WPM#14-042, UBC-SEM); GoogleMaps   (Chamela, Xametla, beach and mangroves, 19.5376°N, 105.0815°W): 1 ♂ and 1 ♀, 22–27.II.2014, H. Proctor & W.P. Maddison ( WPM#14-037, UBC-SEM); GoogleMaps   (Puerto Vallarta, Estero el Salado, 20.662 to 20.667°N, 105.240 to 105.241°W): 1 ♂, 5.II.2014, Maddison, Proctor, Navarro & Cupul ( WPM#14-002, UBC-SEM) GoogleMaps   .

Diagnosis. Among the three species, G. mexicana   sp. nov. can be immediately recognized by having three pairs of dark spots on the dorsum of abdomen (the anterior pair is fused with the oblique anterior dark lines in males) ( Figs 53–56 View FIGURES 53–56 ), while the two anterior pairs of dark spots are always absent in G. forceps   and G. amazonica   sp. nov. Also, male chelicerae of G. mexicana   sp. nov. are divergent (almost parallelly extended forward in G. forceps   and G. amazonica   sp. nov.), with the distal pair of promarginal teeth (DPT) being located close to the remaining cheliceral teeth ( Fig. 52 View FIGURES 51–52 ), while this pair is placed near the articulation of the fang in the other two species ( Fig. 51 View FIGURES 51–52 ). In comparison with G. forceps   , the membranous window of the epigynal plate is narrower ( Fig. 44 View FIGURES 40–44 ) and copulatory ducts are more compact in G. mexicana   ; spermathecae are tubular in G. mexicana   ( Fig. 50 View FIGURES 45–50 ), but more rounded in G. forceps   ( Figs 39 View FIGURES 34–39 , 43 View FIGURES 40–44 ) (the female of G. amazonica   is unknown).

Description. Male (holotype). Total length: 3.25. Carapace orange, 1.53 long, 1.12 wide, 0.81 high; intestinal diverticula can be seen within cephalic area through translucent cuticle; area around anterior median eyes is reddish in live specimens ( Figs 53–54 View FIGURES 53–56 ); faded dark lines extend from posterior eyes and converge to posterior border ( Fig. 57 View FIGURES 57–62 ). Ocular quadrangle 0.66 long. Anterior eye row 0.92 wide and posterior 0.89 wide. Labium, endites and sternum clear ( Fig. 59 View FIGURES 57–62 ). Palp as described for the genus ( Figs 47–48 View FIGURES 45–50 ), with parallel cymbial borders. Chelicera orange, divergent ( Fig. 53 View FIGURES 53–56 ); the cheliceral promargin has three teeth, all gathered proximally; of the three, the most distal (DPT) is larger than the other two (sPT) ( Fig. 52 View FIGURES 51–52 ); the retromargin has a small tooth proximally, and a rounded distal apophysis (RDA) near the articulation of the fang; the fang is sinuous and bears a ventral bump proximally (fvb in Fig. 52 View FIGURES 51–52 ) (see also discussion below). Legs 1234, yellow. Length: I 2.73 (0.69 + 1.19 + 0.85), II 2.38 (0.73 + 0.91 + 0.74), III 2.20 (0.68 + 0.81 + 0.71), IV 2.15 (0.66 + 0.94 + 0.55). Abdomen clear, anteriorly with an oblique dorsal pair of longitudinal dark lines (these are fused with the first pair of dark spots seen in the female), followed by two pairs of dark spots and a small dark spot over the anal tubercle. There are three pairs of tufts of white setae, one anterior and two others between the second and third pairs of dorsal dark spots ( Figs 53 View FIGURES 53–56 , 57 View FIGURES 57–62 ); laterally with a thin dark brown line ( Fig. 58 View FIGURES 57–62 ); ventrally clear ( Fig. 59 View FIGURES 57–62 ). Anterior spinnerets brown, posterior clear.

Female (paratype). Total length: 3.68. Carapace as in male, but lighter and with a median longitudinal stripe of white setae ( Figs 55–56 View FIGURES 53–56 ) and pair of stripes of white setae laterally; 1.42 long, 1.04 wide, 0.49 high ( Fig. 60 View FIGURES 57–62 ). Ocular quadrangle 0.67 long. Anterior eye row 0.89 wide and posterior 0.87 wide. Clypeus densely covered with white setae ( Fig. 56 View FIGURES 53–56 ). Labium, endites and sternum clear ( Fig. 62 View FIGURES 57–62 ). Chelicera yellow. Legs 4312, yellow. Length: I 2.11 (0.67 + 0.87 + 0.57), II 2.03 (0.66 + 0.70 + 0.67), III 2.02 (0.59 + 0.70 + 0.73), IV 2.25 (0.67 + 0.80 + 0.78). Abdomen clear with three pairs of dark brown spots dorsally, and a small dark spot over the anal tubercle; white setae form a median longitudinal stripe and a pair of lateral stripes ( Figs 55–56 View FIGURES 53–56 , 60–61 View FIGURES 57–62 ); laterally with faded brown line ( Fig. 61 View FIGURES 57–62 ); ventrally clear ( Fig. 62 View FIGURES 57–62 ). Epigyne as described for the genus, mostly poorly sclerotized and hard to visualize (inconspicuous copulatory openings on membranous area—only seen in great magnification; inconspicuous glandular portions) ( Figs 44 View FIGURES 40–44 , 49–50 View FIGURES 45–50 ). Spinnerets clear.

Distribution. Known only from the state of Jalisco, Mexico ( Fig. 64 View FIGURE 64 ).
