This male specimen has been considered to be longula because the 

 thoracic segments very closely agree with those of a female at hand 

 identified by McAtee & Malloch as longula. This species is very 

 close to simillima and to signoreti. 0. simillima and longula can be 

 separated by the characters given in the key; besides, the hind margin 

 of the eighth sternum in simillima is undulated medianly while that 

 of longula is straight. 0. signoreti has the head and thoracic segments 

 granulose instead of smooth as in longula. The females of these 

 species can readily be separated by the shape of the seventh sternum. 



Types: Hypotype, male, from Santiago de Cuba, no other data, 

 AMNH; two parahypotypes, same data as hypotype, one in AMNH 

 and other in author's collection. 



Ghilianella megharpacta, new species 



Figures 4, 31 



Male: Head, thorax, and abdomen blackish brown. Legs brown. 

 Middle and hind femora each with three incomplete annuli on apical 

 half. 



Body and legs with scarce short, appressed silvery pilosity. The 

 setae on abdomen in small clusters and with clear areas between them. 



Head heavily granulose. Interantennal spine not well developed, 

 a mere wart. Third antennal segment two- thirds as long as fourth. 



Thoracic segments heavily granulose; lengths of segments: 3.0, 2.9, 

 1.3 mm. Armature of forefemur with inner row consisting of alter- 

 nating long and short spines and between them fine longer setae arising 

 from wartlike bases. Claws of foretarsi two, the inner very short, 

 closely appressed to base of outer. First spine of forefemur at one and 

 one-half times its length from tip of trochanter. Basal half of fore- 

 femur gradually thickened to first spine. 



Abdomen gradually widening to apex of fourth segment, thence 

 parallel sided to middle of seventh. Seventh sternum slightly inflated 

 laterally near apex and constituting widest part of abdomen. Apical 

 angles of terga not produced laterally. Apical margin of terga straight, 

 without median wart, with inconspicuous median ridge, with many 

 subsquare depressions at either side of median ridge and on connexi- 

 vium. Seventh tergum longer than sixth, transversely rugose, shal- 

 low constriction starting on basal third, apical third pointed and not 

 expanded, not surpassing claspers (fig. 31). Hind margins of second to 

 fifth sterna shallowly concave; of sixth more deeply concave medianly 

 and convex on sides; of seventh shallowly concave; of eighth straight. 

 Seventh sternum on lateral margins one-half as long as medianly, 

 slightly shorter medianly than sixth. Eighth sternum visible its 

 entire width. Hypopygium opening upwards. Claspers very large, 

 subtriangular, hind-most margin longer than upper. Upper margin
