Dondale & Redner — Genus Pardosa 
103 
Terminal apophysis slender, pointed, rather short; median ap- 
ophysis slender at middle, with slender distal process (Figs. 39, 42); 
conductor curved on basal margin, with dark, shiny knob near tip 
(Fig. 40). 
Female. Total length 4.80 ±0.64 mm; carapace 2.30 ±0.18 mm 
long and 1.88 ±0.19 mm wide (20 specimens). General color and 
structure as in male but with pale mesal area on carapace, and with 
front and chelicerae pale. Epigynum long (ratio of total length to 
greatest median septum width more than 2:1); median septum with 
expanded posterior part approximately triangular, concave at sides 
(Fig. 76); copulatory tubes with large swellings at lateral margins 
(Fig. 77). 
Diagnosis. Specimens of P. marialuisae can be distinguished from 
the other members of the milvina group by the combination of 
usually pale carapace margins, lack of a setal fringe on leg I, the 
possession of a rather short, pointed terminal apophysis, long 
epigynum (ratio of epigynal length to greatest septal width more 
than 2:1), large swellings at the sides of the copulatory tubes, and 
occurrence restricted south of the Tropic of Cancer. 
Range. Hidalgo, Mexico to Honduras. 
Natural History. Males have been collected from February to 
August and in October, females from January to August and in 
October. Egg sacs were collected in May and August. The only 
habitat recorded on the labels is “along river” at 30 miles southeast 
of Palenque Aqua Azul, Chiapas, Mexico. 
Derivation of Specific Name. The name is derived from that of our 
friend and colleague Maria-Luisa Jimenez of Universidad Nacional 
Autonoma de Mexico.
