Muma, 1986: 17-18, figs 45-46:
"MALE HOLOTYPE: Total length 13.0 mm. Chelicerae 0.9 mm. wide and
3.0 mm. long. Propeltidium 2.1 mm. wide and 2.3 mm. long.
Coloration in alcohol white to
pale to dusky yellow with dusky brownish to purplish markings as
follows: eye tubercle dark with a narrow pale line between the eyes;
chelicerae, all dorsal tergites, pleura, venter, sternites, and malleoli
pale; palpi dusky on tarsus, metatarsus, tibia, and apical ends of the
femur; legs 1 and 2 pale, legs 3 and 4 dusky on metatarsi, tibiae, and
most of the femora.
Structure similar to that
of other members of the genus. Cheliceral dentition as in figure
45. Palpal armature as in figure 46. Chelicera 3.3 times longer than
wide. Propeltidium 1.1 times longer than wide. There is a distinct mesal
tooth on the movable cheliceral finger and 4 fondal teeth on both the
ectal and mesal rows. The spine-like palpal setae seem to be elongate,
strong, dark, cylinder setae."

Island). Known only from holotype.
(1986), in commenting on the uncertainty surrounding identification of
specimens purported to be Ammotrechella geniculata (Koch); see Muma
(1970), whose type series and subsequently designated lectotype are missing,
noted that specimens from South America and the greater Antilles are dark
and well striped with 3 pairs of palpal metatarsal spine-like setae, while
hose from the northern West Indies are very pale or totally unstriped
specimens with 3 to 6 pairs of palpal metatarsal spine-like setae. He
suggested that those with 3 pairs are probably the present species. He
also suggested that this species may be closely related to Ammotrechella
diaspora Roewer, bit that such a theory cannot be ascertained until
males of that species have been collected.
