Psyche 
[Vol. 91 
and Wilton Ivie), deposited in AMNH. Three paratypes from La 
Palma, Costa Rica, deposited in BM(NH). Two paratypes from 
Honduras and Guatemala, deposited in MCZ. Eighty-seven para- 
types from Mexico, Guatemala, and Honduras, deposited in 
AMNH. 
Male. Total length 4.47 ±0.26 mm; carapace 2.40 ±0.1 1 mm long 
and 1.84 ±0.08 mm wide (20 specimens). Carapace with yellow 
orange median and submarginal areas, and with paired dark 
longitudinal bands flanking median area; lateral margins pale or 
dark. Sternum yellow orange. Chelicerae yellow brown; retro- 
margin with 3 teeth. Legs yellow orange; femur I sometimes black 
basally; tibiae and tarsi I with fringe of long lateral setae. Abdomen 
dull yellow brown mesally, darker laterally; venter pale. Terminal 
apophysis connected to mesal swelling by broad curve; median 
apophysis with narrow marginal swelling and with distal process 
weakly hooked (Fig. 14); conductor thin, fluted at tip, lacking 
knoblike process at tip (Fig. 15). 
Female. Total length 4.86 ±0.53 mm; carapace 2.40 ±0.17 mm 
long and 1.89 ±0.15 mm wide (20 specimens). General color and 
structure as in male, but leg I lacking dark pigment and fringe. 
Median septum with posterior part approximately rectangular (Fig. 
56). Copulatory tubes rather stout, diverging (Fig. 57). 
Diagnosis. Males of P. mayana most resemble those of P. sagei, P. 
fastosa, and P. desolatula, but can be distinguished by the narrow 
marginal swelling and weakly hooked distal process on the median 
apophysis, and by the broad curve by which the terminal apophysis 
is connected to the mesal swelling. Females are not anatomically 
distinguishable from those of sagei, fastosa, and desolatula, but all 
of those examined were accompanied by males, or originated in 
localities from which no males of the other species were known. 
Range. Hidalgo, Mexico to Costa Rica. 
Natural History. Males and females have been collected in every 
month except November to January. Females with egg sacs were 
collected in March and July. 
Derivation of Specific Name. The name is derived from that of the 
Maya Indians.
