Elaphidion irroratum (Linnaeus)

( Fig. 15 )

Cerambyx irroratus Linnaeus, 1767: 633 .

Elaphidion irroratum: Linsley, 1963: 83 . Zayas, 1975: 90. Villiers, 1980: 285. Browne et al., 1993: 45. Lingafelter and Micheli, 2004: 50. Chalumeau and Touroult, 2005: 97. Valentine & Ivie 2005:280. [For more complete synonymy, see Linsley, 1963 and Villiers, 1980.]

DIAGNOSIS: The distinct white setose patches on a dark brown background will distinguish this species from other Elaphidion in the region. It is also rather large (11–30 mm), and has unispinose antennae.

DISTRIBUTION: North America; Bahama Islands (North Bimini, South Bimini, Andros, Mayaguana [WIBF], Fortuna [WIBF], Crooked [WIBF], Acklins [WIBF], Great Exuma [WIBF], New Providence, Eleuthra, Cat, Long, and Nurse and Buena Vista Cays [Rugged Island Group] [WIBF]); Cuba, Isla de la Juventud, Jamaica, Hispaniola, Mona, Puerto Rico, St. Thomas [WIBF], St. John [WIBF], Tortola [WIBF], Guana; Great Camanoe [WIBF], Anegada [WIBF], St. Croix [WIBF], Buck Is. [WIBF], St. Barthelémy, St. Martin, St. Christopher, Guadeloupe (Grande-Terre, Basse-Terre), Curaçao, Bonaire. Chalumeau and Touroult (2004) have begun the process of describing the different island variants of this species as subspecies, placing the Puerto Rican and Virgin Islands populations under the name E. irroratum debieni Chalumeau and Touroult.

BIOLOGY: This species was reared from a dead log of Albizia lebbeck (L.) Benth. at Ponce in 1939 ( Martorell 1976). Chalumeau and Touroult (2005) list hosts of Spondias purpurea L., Rhizophora mangle L., Hippomane mancinella L., Haematoxylon campechianum L., and Laguncularia racemosa (L.) Gaertn.
