Ammotrechella tabogana Chamberlin 1919 Ammotrechella tabogana Chamberlin, 1919: 211-212; Roewer, 1934: 606 (as Ammotrechella tobagona [sic]); Muma, 1970a: 48, figs 36-38; Muma and Nazario, 1971: 507; Muma, 1987: 21; Armas, 1996b: 32 (as Ammotrechelle [sic] tabogona); Armas, 2004b: 61.
"Chelicerae above and laterally duaky over yellow with a dark line along each side above and a middorsal dark line, ventrally yellow; fingers rufous proximalIy, dark or blackish distally. Cephalotborax duaky over a yellow ground., with the color deeper, more soIid, over the anterior and lateral borders, and a dark line running from the dark border at eaeh antero-lateral oorner mesocaudad to a median longitudinal pale line. Eye tubercle black, not divided by a longitudinaI pale line. Abdomen pale yellow to dark grayish yelIow excepting a stripe on each side above the longitudinal furrow composed of a series of dark, ohocolate-brown spots, the color of the latter not at all extending below the furrow. Femur of pedipalps yellow, more or less darkened distally; tibia, metatarsus and tarsus abruptly darker, dusky to nearly black. First and second legs yellow. Third legs with femur dusky or brown., yellow beneath at proximal end; tibia dusky or brown, yel1owish at distal end; metatansus aIao brown, yellow at distal end. The fourth leg with femur darker brown, yellow proximally beneath; tibia more blackish, yellow at both ends but the distaJ yellow annulus the larger; metatarsus also dark with a yellow annulus at each end. The anterior end of cephalothorax semicircular as usual. Eyes between one-half and three-fourths their diameter apart. Eye-tubercle in front. with a number of spines of which two are 1onger and stouter than the others. Metatanrus of pedipaJp aJong each edge beneath with a. seriee of five stout and moderately long splnes between which and over ventral surfaoe generally are numerous cylindrical setae in part of equal and in part of greater length than the spinee, with fewer very long, fine-tipped. forms. Tibia with cylindrical setae beneath on distal half. Upper finger of chelicerae bearing beneath three large teeth on the anterior base of the most caudal of which is a.much smaller tooth or dentiole. the three major teeth being followed by three or four small teeth; this finger along dorsal edge with a ridge which is highest opposite the third, or caudal, large tooth. Lower finger having typically two Iarge teeth with a denticle between them. Length, exclusive of chelicerae., 16 mm." DISTRIBUTION: Panama. NOTES: Chamberlin (1919), in introducing his formal description of this species states, "In general. structure and appearance the form resembles Ammotrecha cubae (Lucas); but, aside from differences in coloration, such as the darker color of chelicerae, cephalothorax and third legs, it differs in the armature of the pedipalpa, the metatarsus bearing along each inferior edge a series of five spines instead of four, with numerous cylindrical setae intervening instead of these being absent. It also differs in the more pronounced ridge on the upper finger of the chelicerae above. It differs similarly from the South American A. geniculata (C. L. Koch). It approaches the Central American A. stolli (Pocock); but the tibia of the pedipaJps bears cylindrical setae beneath (female) instead of their being absent, the eyes are more widely separnted, the ocular tubercle lacks the median pale stripe, the abdomen is not colored below the longitudinal furrow on each side, etc."
