Color rather light with a large dark area on side of each segment and 
a small median dorsal one. 
Head with ocelli in three series of 2-6-7 or 3-6-8, beginning in 
front; antennae shorter and more crassate than in FE. plana. 
Segment 1 rather broadly rounded on each side, front margin 
rimmed from behind the eye to the lateral limit; from posterior 
margin just above lateral limit a short stria projects forward and 
upward; above this a stronger sulcus, at least twice as long, nearly 
parallels the raised anterior margin some distance away. 
Ensuing segments with a strong transverse constriction, lacking 
a sulcus, at the anterior third; in its bottom a series of rounded pits 
that are small and distinct across dorsum but larger on the sides; 
dorsum on both sides of constriction smooth and strongly shining, 
the anterior portion less convex, the posterior one strongly convex 
and with the back margin thick and rising abruptly above the next 
segment; pores of moderate size, located a third of the way from the 
constriction to the back margin; lateral striations extending half 
way up sides of anterior segments but gradually becoming more 
restricted toward posterior end of body. 
Gonopods as shown in figure 7e-/. 
Ventral median surface of segment 7 of male elevated into two 
prominent lobes directed obliquely caudad above posterior margin, 
the face of each lobe deeply excavated for tip of gonopod as shown in 
figure 79.

Hototyre: Male, USNM myriapod collection 2651, El Valle, 
Panama, March 22, 1958, E. M. and H. F. Loomis. 
ALLoTYPE: Female, USNM, same collection data as for holotype. 
Paratypss: Male, 4 females, author’s collection, same collection 
data as for holotype. 
Draenosis: The gonopods seem to associate this species with 
E. arius Chamberlin from Colombia. It differs from all species in 
the stout body and in the segments lacking a transverse constriction 
or lateral striations 
Description: This stout species looks more like a rhinocricid 
than a member of this genus; length of largest specimen, a female 
with 56 segments, 25 mm., diameter 1.5 mm.; males with 51 and 52 
segments, respectively ; all specimens have 2 legless segments preceding 
the terminal one. Color very light, dorsum without median dark
