Holotype. Male from Bosques al Sur de Quintero, Valparaiso 
Province, Chile, 20. II. 1973 (Luis Cartagena) in the Museum of 
Comparative Zoology. It was found under a leaf. It is named for 
the collector. The specific name is a noun in apposition. 
Description. Carapace, sternum, legs olive-brown. Tarsi of legs 
light colored. Dorsum of abdomen with a black pattern and white 
pigment spots in areas without black (Fig. 11). Sides and venter 
black. Venter with a pair of white spots side by side. Posterior 
median eyes 0.6 diameters of anterior medians. Laterals the radius 
of anterior medians. Anterior median eyes slightly more than their 
diameter apart, almost touching laterals. Posterior median eyes 
slightly less than one diameter apart, about their diameter from 
laterals. The labium and endites are modified, the endites with a 
distal brush and the labium with a transparent lobe on each side 
(Fig. 14). Total length 2.0 mm. Carapace 0.98 mm long, 0.90 mm 
wide, 0.76 mm high. First femur, 1.52 mm. Second patella and 
tibia, 1. 00 mm; third, 0.69 mm; fourth, 1.18 mm. 
Dipoena species feed on ants. This specimen is unusual because 
unlike others of the genus, the endites seem to be specially adapted 
probably for holding the legs of the ant while the spider pierces it 
with its fangs. 
Diagnosis. This species is close to Dipoena pumicata (Keyserling) 
but differs from this and related species by the twisted embolus and 
plain projecting conductor of the palpus (Fig. 12).
