42. Epilohocera armata Smith 



Figure 39a 



Epilohocera armata Smith, 1870, p. 151, pi. 5: figs. 2-2b [type-locality: Cuba 

 (probably Baracoa, Provincia de Oriente)]. — Rathbun, 1905, p. 316, pi. 18 

 (XVI) : figs. 1, 6. 



Diagnosis. — Carapace strongly convex longitudinally and trans- 

 versely, especially branchial regions, rather broad, about three-fifths 

 as long as wide; cervical groove nearly obliterated, concave anteriorly; 

 anterolateral margin armed with several prominent, sharp teeth 

 anteriorly, decreasing in size posteriorly and disappearing at about 

 widest part of carapace, no distinct notches at end of cervical groove 

 or near outer orbital angle; front delimited dorsally by strong, tuber- 

 culate, transverse crest, true margin barely \dsible in dorsal view. 

 Third maxilliped with merus broad, distolateral margin regularly 

 convex; exopod extending beyond ischiomeral articulation. Pereiopods 

 not unusually long or slender. Chela without prominent, swollen pro- 

 tuberance on outer surface at base of fingers. First pleopod of adult 

 male armed distaUy -wath scattered, short stout spines; elongate lobe 

 directed posteriorly in situ. A fairly large species, maximum carapace 

 length in midline about 45 mm. 



Habitat. — In and near fresh water. 



Distribution. — Cuba.

Epilohocera cuhensis Stimpson, 1860, p. 234 [type-locality: upper Rio Yateras, 

 Provincia de Oriente, Cuba]. — Rathbun, 1905, p. 315, text-fig. 103, pi. 18 

 (XVI): fig. 7. 



Diagnosis. — Carapace strongly convex longitudinally and trans- 

 versely, about two-thu'ds as long as wide; cervical groove nearly 

 obliterated, somewhat sinuous, strongly concave anteriorly toward 

 center of carapace, straight or curving slightly posteriorly near 

 anterolateral margin; anterolateral margin nearly entue, anterior 

 part with few very low, elongate tubercles, no notch at end of cervical 

 groove, margin concave near outer orbital angle; front curving down- 

 ward very gradually, not delimited dorsally by transverse crest. 

 Third maxilliped with merus broad, lateral margin regularly convex, 

 distal margin slightly concave; exopod extending beyond ischiomeral 

 articulation. Pereiopods rather slender, not unusually long. Chela 

 without prominent, swollen protuberance on outer surface at base
