Total length, 2 7-10, ¢ 4 millim. 
Carapace deep brown, with the ocular area yellow. Mandibles, maxillz, and sternum brown, the latter with 
a central yellow band. Coxe, trochanters, and the other segments of the legs dull yellow, with the 
apices of all slightly suffused with brown. Abdomen dull yellow-grey, with a central folium very 
similar to that present in the two next species, but the second diverticulum is not so much dilated as in 
M. spinipes, nor so pointed as in M. incrassata, but usually rounded ; sides mottled with rich brown ; 
ventral area black, with a central pale line and two spots in front of the spinners. The legs are much 
shorter in proportion to the carapace than in M. spinipes, about one-fourth longer than the whole body. 
Femur i. with 3-5 spines in the apical half, ii. without spines. Vulva of the same type as in the next 
two species, but the scapus is narrower than in M. spinipes and not dilate apically as in M. wecrassata. 
g. Carapace deep brown, ocular area slightly paler; mandibles and sternum brown, the latter with a central 
yellow line. Legs yellow, apical two-thirds of femora i., ii., iv. and apex of iii., patella and apex of 
tibia, protarsus, and tarsus brown. Abdomen entirely black, with the folium and anterior ,~\-shaped 
marks outlined in white; lateral and ventral areas black, the latter with the usual central line and pair 
of white spots before the spinners. Femur i. of legs with 3 dorsal and a cluster of 5-7 long spines on
