MARTELLA N. 



Cephalothorax not long, moderately high, sides parallel, 

 highest at dorsal eyes, cephalic part on a slightly higher plane 

 than thoracic. Quadrangle of eyes one-fifth or one-fourth 

 wider than long, equally wide in front and behind or wider in 

 front, occupying one-half of the cephalothorax. Anterior eyes 

 in a straight or slightly curved row, touching; middle twice as 

 large as lateral. Second row of eyes half- waj' between first and 

 third rows. Dorsal as large as lateral eyes, in a row as wide or 

 nearly as wide as the cephalothorax at that place. Lip nearly 

 as wide as long, or a little wider. 



Martella is near Salticus, Sarinda and Zuniga, but is 

 shorter and more compact, with the quadrangle never wider 

 behind, as in Salticus, and occupyinghalf of the cephalothorax, 

 which is not the case with any of these closely related genera.
