( Figures 41–42 , 47 . Map 7)

Sicoderus ivieorum Anderson 1999: 129 . Holotype male ( USNM) from St. John , Virgin Islands, examined in 1999.

Description: Length male, 5.2–6.2 mm; female, 4.8–7.2 mm. Integument black, shining. Eyes separated by a distance about one-half width rostrum at midlength. Rostrum 0.97–1.00x length elytra in male; 1.09–1.17x length elytra in female. Antennal insertion at about midlength in male and female. Prothorax constricted anteriorly, globose, widest at about anterior one- third; punctures well-separated, sparse, very fine and shallow on disk, slightly deeper and larger in anterior one-quarter and very slightly deeper on flanks; with scattered, erect setae along anterior constriction. Elytra in dorsal view distinctly widest at midlength, lateral margins convergent both anteriorly and posteriorly; humeri fully reduced, not at all angulate; with isolated, erect but short (perhaps abraded or broken), setae in sutural region. Strial punctures evident, shallow, moderately fine; striae not impressed throughout length. Membranous wings lacking. Abdominal ventrite 1 of male moderately raised in middle near apical margin forming a moderately elevated tubercle with two small subcontiguous patches of setosity at tip; of female, moderately swollen in middle near apical margin. Ventrite 5 of male with rounded shallow impression in apical three-quarters; of female, uniformly convex. Legs with all femora with ventral margin with distinct ventral tooth; tooth slightly larger on anterior legs; tarsal claws with small basal tooth. Aedeagus (fig. 47) widest at about apical 1/3 but also widened at apex, internal sac with pair of elongate basal sclerites very slightly convergent, each with short basal outwardly directed extension. Female not dissected.

Material examined: 3 males, 8 females. PUERTO RICO: Cambalache Forest Reserve, 28.VII.1979, G.B. Marshall (2 males, 6 females; CWOB) . Cambalache State Forest , 3.VIII.1999, at night, C.W.

Valentine (1 male; FSCA) . Tortola Island, Chalwell , 1550’, at light, IX.2011, C. Petrovic collector (1 female; FSCA). Additional specimens were examined by Anderson (1999).

Comments: This species was described by Anderson (1999) from specimens collected on the Virgin Islands and British Virgin Islands. Anderson (1999) also recorded a single female of a Sicoderus species thought to be S. ivieorum from Puerto Rico. Male specimens now available for study from Puerto Rico confirm that this species is S. ivieorum .
