below. Anal valves not spined. In the posterior gono- 
pods of the male the coxa without trace of spines and set 
off distinctly from the telopodite; telopodite long and 
slender, not at all laminate and entirely without lobes or 
branches. The inner lamina of the anterior gonopods 
much produced distad, presenting on the outside at level 
of the gonocoel a lobe directed proximad and on mesal 
side near distal end a large T-shaped lobe with one arm 
directed distad and the other proximad. 
Generotype : Zantekius weberi, new species. 
This genus differs from Mardonius in lacking a femoral 
lobe or spine on the posterior gonopod and from Eume- 
kius in having an ectal cone or lobe on the median lamella 
of the anterior gonopod as well as in having the con- 
spicuous mesal lobe. 
Zantekius weberi, new species 
Metazonites black about caudal borders, anteriorly 
more grayish, the last segment entirely gray or grayish 
brown. Head with face below level of antennae reddish. 
Legs and antennae red, contrasting sharply with the dark 
body. 
Labral excavation very shallow. Labral pits 2-2, the 
front of head elsewhere smooth, wholly without rugae. 
Eyes with inner angles extending mesad a little beyond 
base of antennae, the two separated by somewhat more 
than their transverse length ; individual ocelli convex and 
distinct. Median sulcus across vertex line, ending in a 
slightly depressed pit at level of inner angles of eyes. 
No interocular sulcus evident except faintly for a short 
distance each side of end of vertigial sulcus. Antennae 
reaching to third segment. 
Collum moderately narrowing on each side from level 
of eye ventrad; in the male produced forward at lower 
anterior corner, with three deep sulci in addition to the 
margining sulcus as shown in the accompanying figure 
(Fig. 1A) ; not produced in the female. 
Encircling striae of prozonites of the other segments 
fine, mostly about six in number. The surface of the 
metazonites above and laterally entirely smooth and shin-
