(Figs. 7, 37–40)  
 Attelabus uviferae Marshall, 1926.   
 Type locality: Haiti   
 Type data: Five syntypes (2 males & 3 females) were recorded by Marshall (1926). Four syntypes (2 males and 2 females) from the BMNH and one female syntype from the USNM were examined. Lectotypes are here designated. Lectotype male (minuten pin/card mounted) with the following labels: TYPE [circular label with red margin]; West Indies, St. Louis, Haiti, 10-vi-1925, G. N. Wolcott [white, rectangular, hand written]; Pres. by Imp. Bur. Ent. Brit. Mus. 1926-443 [upside down, rectangular]; Ex. sea grape, Coccoloba uvifera L.; Type, Euscelus uviferae Mshl., male symbol [white, rectangular, hand written]. Allolectotype female (minuten pin/card mounted): [same data as the lectotype except first label is a circular COTYPE label with a yellow margin]. Paratypes: 1 male and 1 female, Acc. # 436-25, St. Louis, Haiti, June 10, 1925, G. N. Wolcott Coll., ex. Coccoloba uvifera, Euscelus uvifera Mshl., Cotype, (BMNH); 4 males and 2 females [same as previous except 1 male with red Cotype No. 40010 U. S. M. N. Label].   
 Type holder: The Natural History Museum, London, England (BMNH) and The United States National Museum, Washington, D.C. (USNM).   
 Specimen data: HAITI: 4 males & 1 female, St. Louis, Haiti, Acc. # 432-25, June 10, 1925, GN Wolcott coll.; 1 male, Torbeck, Haiti, Sept. 4, 1930, on raisin de mar, HL Dozier collector (BMNH). 2 males & 2 females, aux Cayes [?], Haiti, Dec. 8, 1937, #149-37, GN Wolcott (USNM); DOMINICAN REPUBLIC: 1 female, St. Domingo, coll. Kraatz (DEIC).   
 Description: Color: Reddish-brown throughout, antennae paler; middle and hind legs yellowish; elytra with raised reticulate yellowish intervals except for two reddish-brown median spots near basal 1/4 and reddish-brown lateral margins. Size range: Male (n = 9): 7.3 x 3.3 mm to 7.7 x 3.4 mm; Female (n = 7): 6.7 x 3.2 mm to 7.2 x 3.4 mm. Head slightly longer than wide, sub-rectangular, only slightly widened at base, moderately punctured, interspaces rugose, transversely strigate at base; frons narrow, about 1/3 as wide as rostral base; with smooth wide median channel. Rostrum shorter than head, distinctly widened beyond antennal insertions, apex 1/3 wider than rostral base, moderately to densely punctured. Antennae short, shorter than head and rostrum together; scape ovo-globose; funicle segment 1 short, ½ as long as scape, bead like; funicle segment 2 twice as long as segment 1; segments 3–5 short, subequal, bead like, subequal to segment 1; segment 6 subequal in length to segments 3, 4 or 5 but more widened apically; segment 7 sub-quadrate, much wider than 6, about as wide as basal club segment; basal and middle club segments twice as wide as long, subequal; terminal club segment slightly longer, acuminate. Pronotum wider than long, widest across base, densely and irregularly punctured; interspaces reticulate; with pair small, shallow, pit like impressions each side of middle; with median longitudinal line like impression; sides evenly arched out; anterior collar weakly defined through middle, coarsely punctured, narrowed laterally; anterior basal carina smooth, wide through middle; posterior basal carina narrow, at middle about ½ as wide as anterior carina. Scutellum sub-triangular, at base twice as wide as long, moderately punctured; posterior margin broadly rounded. Elytra longer than wide, slightly narrowed from humeri to apices; strial punctures large deep, irregularly spaced; many punctures fused and forming short grooves; most intervals and interspaces raised, yellowish, reticulate; humeri weakly angulate. Abdominal ventrites with thin brush like median setosity.   
 Femoral sexual dimorphism: Both sexes have a large beak-shaped disti-ventral projection on the profemur. The male also has a dark shiny tubercle on the upper 1/3 of the profemoral inner face.   
 Distribution: All specimens examined, except a single female from the Dominican Republic, were from Haiti.   
 Comments: The species is recognized by the reddish-brown color and the raised yellowish reticulate intervals of the elytra. The female has finer punctures on the head and the abdominal sterna are less setose.   
 Host plant: Wolcott (1926) reports the leaf rolls of this species on sea grape, Coccoloba uvifera (Linnaeus), along the south coast of Presque Isle, Haiti.
