New genus, new species 2 [sic, 3]; Anderson 2002:7.

Types. Holotype male labelled ‘‘ Costa Rica-Puntarenas / Las Cruces — Wilson Bot. / Res. 25.V.1989 / D. Brzoska’ ’ ( CMNC) . Allotype female labelled ‘‘ Fila Matajambre Osa, A [rea de].C[onservación]. Osa , Prov./ Punt [arenas], Costa Rica. 300–740 m. 7 May/1994, M.A. Zumbado, L.N./276600-525900 #2902’’ and with INBio barcode 1964345 ( INBC) .

Derivation of Species Name. The species is named after my mother Daisy Anderson (1923–1999).

Identification. The one known male of this species has the inner margin of the front femora with only an angular swelling at the apical one-third ( Fig. 41 ). The rostrum of the male has only moderately coarse punctures ( Fig. 36 ) in contrast to the dorsally medially carinate rostrum ( Fig. 46 ) of D. huetheri . Also, in the one known female, the rostrum is coarsely sculptured and carinate in D. huetheri ( Figs. 47–48 ), but only finely punctate in the one known female of D. andersonae ( Fig. 37 ). In D. andersonae , article 3 of the tarsus is about as long as wide, about one and one-half times the width of article 2, and is sub-cordiform with the maximum width near the apex and the lateral margins convergent to the base ( Fig. 39 ).

Description. Female length, 13.4 mm; width 5.6 mm. Male, length, 12.5 mm; width 5.0 mm. Color black, elytra with irregular reddish maculations in basal two-thirds along intervals 3–8; integument with noticeable micropilose tufts or nodules, especially on elytra.

Rostrum with length two-thirds length of pronotum; very slightly laterally compressed throughout, arcuate ventrally; in male, densely and irregularly punctate dorsally and laterally in basal one-half, punctures finer, less dense in apical one-half; in female, punctures uniformly small, shallow; base of rostrum expanded in dorsal view; in lateral view widest at base. Scrobe with posterior margin separated from anterior margin of eyes by about two times width of base of scape. Antenna with club subquadrate, apex slightly wider than base; apical pilose part about one-quarter length of basal glabrous part. Pronotum with lateral portions of disk and flanks moderately densely, irregularly, shallowly punctate, punctures with single robust, short seta at middle, surrounded by dense micropilosity; disk very slightly convex, no subbasal impression; with distinct glabrous median area and smaller irregularly shaped glabrous lateral areas in basal twothirds. Pronotum with length greater than width; width much less than width elytra at base. Elytra with length more or less twice length pronotum; greatest width at humeri; intervals impunctate, flat, with numerous distinct elongate-oval micropilose tufts or nodules, tufts and micropilosity concentrated at apical calli; striae with indistinct, shallow, small punctures. Scutellum rhomboidal, length subequal to width, flat. Pygydium flat, punctate throughout; apex subtruncate; apically with dense short, robust setae. Ventrally with hind coxae separated by about width of coxa. Lateral portions of meso- and metasternum, and visible abdominal segments 1 to 5 sparsely, shallowly punctate; last visible abdominal segment flat, deflexed ventrally at apex. Legs moderate, regularly punctate, especially on outer face of femur; femur clavate, hind femur reaching apex of visible abdominal segment 4; male with inner margin of front femur with low, angular swelling at apical one-third, angulation less distinct on each of middle and hind femur; female with inner margin of each femur lacking angulation, uniformly rounded; inner margins of each tibia straight, with scattered, short, slightly curved fine setae in apical three-quarters, setae of more or less uniform length, front tibia also with small acute denticles interspersed between setae. Tarsi each with article 3 moderately dilated, sub-cordiform; width at apex about twice width at base, about one and onehalf times width of article 2 at apex; pilose ventrally except glabrous in basal one-half in V-shaped median area; apical margin of article 3 slightly, broadly emarginate. Aedeagus with median struts transversely fused for short length at basal one-third. Tergite 8 with length one and one-half times width at base. Female genitalia not examined.

Sexual Variation. The male specimen has a slight angular swelling at the apical one-third of the inner margin of the front femur as well as similar but less pronounced projections on each of the middle and hind femur. These projections are absent in the one female examined. In addition, the male has the dorsal and lateral surfaces of the rostrum with much coarser, denser punctures than in the female.

Distribution. Costa Rica (Puntarenas).

Natural History. The male holotype was collected in a upper montane evergreen forest on the grounds of the Robert and Catherine Wilson Botanical Garden.
