Zeadolopus puertoricensis (Peck) 1978: 252 ; Newton 1983: 174 (ex Apheloplastus ). Type male in CNCI, seen. Type locality: Forest at Aguas Buenas, Puerto Rico .

Diagnosis. Body strongly convex. Length 1.0– 1.5 mm; greatest width 0.6–1.1 mm. Uniformly light reddish brown, shining, without microsculpture. Head finely, sparsely punctate. Antennal club moderately slender. Eyes large. Pronotum finely, sparsely punctate; sides rounded, posterior angles rounded. Elytral striae weakly to not impressed; strial punctures larger posteriorly, strial rows not reaching base; interstriae minutely, sparsely punctate. Flight wings fully developed. Vertical face of mesosternum broad, not carinate. Metasternum coarsely, densely punctate laterally; punctures smaller medially. Posterior margin of male mesofemur expanded, forming small median and larger apical toothlike processes; female with smaller apical process. Posterior margin of male metafemur expanded apically to form large toothlike process; rounded expansion in female. Meso- and metatibia broad and spinose in both sexes. Male with more dense setae on pro- and mesotarsi. Median lobe of aedeagus ( Fig. 62 ) elongate, broad, with inwardly curved paired apices. Parameres slender, extending to or slightly beyond apex of median lobe, each bearing 2 apical setae. Inverted internal sac with median rod-like structure and anterior pair of shorter sclerites converging and widening apically, with lateral processes. Spermatheca of 2 connected spheres.

Distribution. Known only from the islands of Puerto Rico, Mona Island, and the Virgin Islands (Buck, Guana, St. Croix, St. Johns, St. Thomas, Tortola). Previously known localities, from Peck (1978). Puerto Rico. 15 mi S. San Juan, Aguas Buenas, forest at Aguas Buenas caves.

Remarks. The Virgin Islands (except St. Croix) are all on the same marine bank as Puerto Rico, and all the islands were connected as dry land during times of Pleistocene glacial low sea levels. In contrast, Mona Island (west of Puerto Rico) and St. Croix (southeast of Puerto Rico) are on their own marine banks and have not been connected by dry land with Puerto Rico. This suggests dispersal by flight across the water gaps to Mona and St. Croix.
