combination of characters: spiracle clearly visible, not concealed by 
the fourth coxa, dorsum smooth, without any kind of granulations 
or spines. Eyes and corneal lenses absent. Fourth coxa normal, 
without large spines. Size about 3 mm. 
Habitat. These animals were found on flood debris on silt banks 
in a side passage about 150 m from the entrance. Coffee River 
Cave, also called Princess Alice Cave, with a very irregular floor, 
carries a torrential river subject to heavy flooding. Oxford Cave 
is a smooth-floored, large, walk-in cave with no standing water, 
inhabited by abundant fauna including a large bat colony. 
Records. Besides the holotype and female paratype there are two 
male paratypes and three immatures from Oxford Cave at the same 
locality. 
Cynortina Banks 1909 
Type species by monotypy C. tarsalis Banks 1909 from Costa Rica. 
If one applies the limited characters for generic classification 
pointed out by Goodnight and Goodnight (1953), the genus 
Cynortina becomes an integration of sixteen different Roewer genera. 
Thus the Mexican and Central American phalangodids are divided 
at present into eight recognized genera. 
Specimens examined possessed intermediate characters between two 
genera, Cynortina and Sitalcina , the only difference between them 
being the position of eye tubercle. It is removed from the anterior 
margin of cephalothorax in Cynortina and not removed in Sitalcina 
(Briggs, 1968). 
But, this difference is not so abrupt as once thought, because in 
the studied specimens, the eye tuburcle is only slightly removed from 
the anterior margin. On the other hand, there are no great differ- 
ences between these two genera, and some characters of the ex- 
amined specimens agree better with Sitalcina , such as tarsal formula, 
others with Cynortina , as the position of the eye tubercle. Tradition 
might call for the establishment of a new genus, but restricted 
separation of genera, as adopted by Goodnight and Goodnight 
( J 953), does not support such division. It is thought best to place 
them in the genus Cynortina as its species range across Central 
America and the West Indies, while all but one species of Sitalcina 
have been found in California. Perhaps Sitalcina should eventually 
be synonymized with Cynortina. 
The definition of Cynortina is revised as follows. Phalangodids 
with eye tubercle rounded above, unarmed or with small tubercles 
or spinules, usually removed from the anterior margin of cephalo-
