at least at the subgeneric level because of the distinctive habitus of 
its component species. 
The Seam ay Cave beetle does not appear to be close to Mex- 
isphodrus despite their cavernicolous habitats and despite their in- 
clusion within the colpodines. In Mexisphodrus there are well-formed 
eyes or eye rudiments, the head is rounded, the pronotum is more 
or less cordiform with very broadly reflexed sides, the elytral humeri 
are well developed and prominent, and the color is dark violaceous- 
ferruginous. In the Seamay Cave beetle the eye rudiments are 
minute, the head is twice as long as wide and its sides are subparallel, 
the pronotum is barrel-shaped, the elytral humeri are completely 
rounded, and the color is rufotestaceous. 
Speocolpodes, new genus 
Slender, elongate, rufotestaceous cave beetles with minute vestiges 
of eyes and wings; front and middle tarsi with penultimate segment 
deeply and asymmetrically bilobed ; head twice as long as wide, sides 
subparallel ; pronotum widest at middle, hind angles blunt and obtuse. 
Integuments generally glabrous; microsculpture on dorsum of head 
obsolete, obsoletely transverse on pronotal disc, finely and densely 
transverse on elytra. 
Eye rudiment visible only as minute, translucent spot beneath 
cuticle ; labrum with anterior margin broadly convex, 6-setose ; two 
clypeal setae; clypeofrontal groove joining postantennal groove and 
terminating in lunate depression between anterior and posterior 
supraorbital punctures. All mouthparts elongate and slender; mandi- 
bles falcate, right mandible with large tooth ; maxillary palps with 
terminal segment fusiform, a little shorter than penultimate segment; 
glossa with apex broadly rounded and bisetose; labial palps bisetose; 
mentum tooth grooved, truncate; two prebasilar setae each side of 
submentum behind suture. 
Pronotum barrel-shaped, longer than wide, widest at middle, apex 
slightly narrower than base; two pairs of marginal setae; hind angles 
obtuse and somewhat rounded, not produced. Metepisterna short, 
24 as wide as long. 
Elytra elongate-elliptical, humeri completely rounded, subapical 
sinuation absent ; scutellar stria very brief, obsolescent ; scutellar 
puncture setiferous; two disca.1 punctures in apical half, on third 
interval against second stria; umbilicate series 6 + 2 + 6, seventh 
and eighth punctures rather widely spaced ; a single puncture near 
apex of seventh stria.
