Eucalandra setulosa (Gyllenhal)

( Figs. 1–2 , 11–12 , 22)

Sitophilus setulosus Gyllenhal in Schoenherr, 1838: 969 (type not examined).

Eucalandra setulosa ; O’Brien & Wibmer 1982: 221; Wibmer & O’Brien 1986: 366; Alonso-Zarazaga & Lyal 1999: 67.

Diagnosis. Length 5.4–7.2 mm. Integument ( Figs. 1–2 ) black (most of range) or with elytral humeral area and declivital area with red maculations ( Ecuador). Antennal scape ( Figs. 11–12 ) short and stout, club with basal shiny, glabrous portion comprising basal 0.6 of club length. Front femora with inner margin simple, occluding area on front tibiae simple, not modified; middle and hind femora and tibiae with inner margins simple. Front tibia with inner margin distinctly serrate throughout length. Hind tibia very slightly curved inwardly along outer margin. Tarsi with ventral pilose pads limited to narrow band across apex of tarsite 3. Tibiae with subapical tooth small, much smaller than larger, curved apical tooth. Large white flat scales ( Figs. 1–2 ) present on lateral margin of pronotum, mesepimeron, metepisternum, lateral portion of metasternum, elytral intervals 3 and 5 at base and intervals 3, 5 and 7 (in some specimens) just anterior to declivity.

Distribution. Mexico south through Central America into South America and onto the island of Trinidad ( Fig. 22).

Biology. Specimens from Venezuela were recorded from the bamboo Phyllostachys and a specimen from Trinidad was taken from felled bamboo. Specimens from Ecuador have been collected in numbers on felled and split culms of the bamboo Guadua angustifolia as well as in association with corn ( Zea mais) and Inga sp., and specimens from Venezuela and Colombia have also been found on corn. At United States border ports specimens have been intercepted in bamboo and bamboo slats as well as in banana.

Comments. All specimens examined from Ecuador have the elytral humeral and the declivital areas with reddish maculations. No distinctions other that these color differences were noted in E. setulosa from elsewhere (including the male genitalia). The fully black specimens and those with red maculations are considered conspecific.
