Diagnosis: Moderately large, 10-18 mm in total body length; elongate-narrow in form, black or black with red markings; antennal funicle of 6 articles, apex extended beyond posterior margin of eye, antennal club with apical pilose part one-fifth to one-third length of basal glabrous part; rostrum cylindrical, curved ventrally; anterior margin of pronotum straight behind eye, pronotal disk and-or elytra with scattered nodules of short, erect setae; front femur of male with distinct subapical swelling or tooth on inner face; tarsus of 5 articles, but article 4 small, located at very base of article 3, article 3 slightly wider than 2 and not distinctly bilobed ventrally; front coxae narrowly separated; pygydium exposed beyond elytra; metepisternum narrow, length 3 or more times width; scutellum rhomboidal or subcircular, widest at middle.

  Key to species of Daisya in Costa Rica and Panama  
1 Antenna with club with apical pilose part about one-third length of basal glabrous part, male with inner margin of front femur with distinct tooth at apical one-third, elytra black with small, indistinct reddish marking at lateral margin at basal one-third D. obriani Anderson
  - Antenna with club with apical pilose part about one-quarter to one-fifth length of basal glabrous part, male with inner margin of front femur with angular swelling at apical one-third, elytra black with extensive reddish markings 2
2 Tarsus with article 3 about as long as wide, about one and one-half times width of article 2, shape subcordiform, maximum width near apex, lateral margins distinctly convergent towards base; male rostrum with only moderately coarse punctures, female rostrum finely punctate D. andersonae Anderson
  - Tarsus with article 3 longer than wide, only slightly wider than width of article 2, shape sub-oval, maximum width towards midlength, lateral margins arcuate; male and female each with rostrum with distinct dorsal median carina, bordered laterally by row of sunken contiguous punctures throughout length D. huetheri Anderson


Daisya andersonae Anderson

Distribution: Costa Rica

Natural history: The holotype was collected in an upper montane evergreen forest on the grounds of the Robert and Catherine Wilson Botanical Garden.


Daisya huetheri Anderson

Distribution: Costa Rica and Panama; also in South America.

Natural history: Adults have been collected in wet upper montane and cloud forest habitats.


Daisya obriani Anderson

Distribution: Costa Rica and Panama.

Natural history: The allotype was collected in lowland rain forest in Panama among dead leaves of a broken palm, Oenocarpus mapora, that was brought up from the ground and hung in the canopy to attract beetles. The holotype was collected in a malaise trap in lowland rain forest.
