Of the species so far recorded having similarly built gonapods the 
nearest related is M. aphroditce, Attems, from Cyprus. Yet it is said to 
have a short but well-marked occipital sulcus, few sulci on the lateral lobe 
of the collum, and a short, broad, and rounded callus at the mandibular 
stipe in the male, all structures absent in the Mesopotamian species. 
Furthermore, the apex of the gonapods seems to be different, as it is 
described (and figured) in aphroditce as a plain, folded lamella, tapering 
and rounded apically. Moreover, the peltogonapods are more narrow and 
sharpened in Attems’ species, and the two posterior tubercles are very 
different from each other in size and shape. 
Pachyiulus {Dolichoiulus) creticus, Verb., likewise resembles Evansi ; it 
is readily distinguished from the latter by the want of occipital setse and 
by the more simple structure of the apex of the gonapods. 
From other congeneric species of the same eastern region, M. Evansi 
may be known as follows: — From M. sporadensis, Verb., in having 
occipital setae and a simple (not ramose) mesornerite ; from M. turcicus, 
Verb., in having distinct ocelli and the anal segment rounded ; from 
M. domesticus, Att., in having no prominent mandibular callus ; from 
if. cedrophilus, Att., in having the pores far away from the suture; 
from M. ohscurus, Att., in having convex anal valves and tarsal soles ; 
from M. polyzonus, Att., if. sinaimontis, Verb., and if. Festoe, Silv., by a 
much lower number of body segments (41-47, as against 79-81, 63, 
and 74); etc
