Ctenocolum biolleyi Kingsolver & Whitehead (1974a) : 287, 303, 311 (original description, key, characters, distribution, figures, type-locality: Costa Rica, San Jose, host plant); Janzen (1977): 417 (host plant); Janzen (1978): 183 (host plant); Janzen (1980): 947 (host plant); Johnson & Kingsolver (1981): 418 (catalog); Udayagiri & Wadhi (1989): 78 (catalog).

Type material. Ctenocolum biolleyi Kingsolver & Whitehead, 1974a . Holotype deposited in USNM, female: “San Jose/ Costa Rica ” [white label handwritten in black]; "P.Biolley/ Collector" [white label handwritten in black]; “Collection/ Chittenden” [white label printed in black]; "habitus/ drawing" [white label handwritten in black]; "luxurianus" [white label handwritten in black]; "Buchus?/ Teosiute (Rhea/ na luxurians )" [white label with black margin, handwritten in black]; “ HOLO / 72801” [red label printed in black, 72801 handwritten in black]; “ TYPE ” [red label printed in black]; “ HOLOTYPE / Ctenocolum / biolleyi / Kings. + Whd.” [white label with red margin, HOLOTYPE letters printed in red, remainder handwritten in black]; “♀” [white label printed in black]. 1 paratype deposited in USNM, female: “San Jos/ Costa Rica ” [white label handwritten in black]; “P.Biolley/ Collector” [white label handwritten in black]; " Bruchus ?/ Teosiute (Rheana/ luxurians " [white label handwritten in black]; “Collection/ Chittenden” [white label handwritten in black]; "luxurianus" [white label handwritten in black]; "drawn" [white label handwritten in black]; " PARATYPE / Ctenocolum / biolleyi / Kings. + Whd." [white label with blue margin, PARATYPE letters printed in blue, remainder handwritten in black]; “♀” [white label printed in black].

Note. Kingsolver & Whitehead (1974a) indicated that the holotype and the paratype are deposited in the USNM. The holotype and paratype received from USNM were examined and coincide with the description.

Diagnosis. Ctenocolum biolleyi differs from all other species by having tooth of stria 4 closer to anterior margin of elytra than to base tooth of stria 3.

Redescription. BL: 4.2–4.4 mm; BW: 2.8–2.9 mm.

Integument. Dorsum mostly black with reddish brown area near scutellum. Pygidium reddish brown. Ventral region, reddish brown and dark brown. Middle femur and tibia brown; hind femur reddish brown and dark brown.

Pubescence. Pronotum brown and yellowish gray, black and white; sparse setae exposing the integument forming an oval, wide area from anterior to posterior region divided by transversal and longitudinal strip of denser setae and in one small area on each lateral region ( Fig. 9 View FIGURES 8 – 16 ). Elytra slightly variegated with brown, black and white setae; interstria 3 at base with short dense strip of white setae ( Fig. 9 View FIGURES 8 – 16 ). Pygidium white, dense except four lateral small areas and a larger area from basal to median region ( Fig. 47 View FIGURES 47 – 52 ). Ventral region brown and white ( Fig. 54 View FIGURES 53 – 60 ).

Head. Ocular sinus 0.3 mm; ocular index 4.7 mm; length of eyes in frontal view behind sinus 0.13 mm ( Fig. 23 View FIGURES 22 – 30 ). Frons with frontal carina ( Fig. 23 View FIGURES 22 – 30 ).

Prothorax. Pronotum with median gibbosity slightly elevated, not divided by longitudinal and transversal sulcus ( Fig. 54 View FIGURES 53 – 60 ); lateral gibbosity moderately elevated; basal lobe with depression and slightly emarginated ( Fig. 9 View FIGURES 8 – 16 ).

Mesothorax and metathorax. Elytra, striae with punctures moderately impressed; conspicuous teeth at base of striae 3 and 4; tooth of stria 4 closer to anterior margin of elytra than base of tooth of stria 3; stria 6 conspicuosly impressed ( Fig. 9 View FIGURES 8 – 16 ). Hind femur ( Fig. 67 View FIGURES 66 – 71 ) on external ventral margin with toothed carina; without denticles above of external ventral margin; pecten with 10 teeth. Hind tibia ( Fig. 67 View FIGURES 66 – 71 ) strongly emarginated beside mucro; lateral coronal denticles present.

Abdomen. Pygidium longer than wide, subtriangular, at median basal region with moderately impressed punctures ( Fig. 47 View FIGURES 47 – 52 ).

Note. The male is unknown and the redescription was done only based on two female specimens. Besides, the antenna is not present in the specimens examined.

Distribution. Neotropical region: Costa Rica (San Jose).

Host plant (Tables I–II). Papilionoideae : Lonchocarpus eriocarinalis Micheli.

Note. According to Kingsolver and Whitehead (1974a) and label of the holotype, Zea luxurians (Durieu & Asch.) R. M. Bird. (= Reana luxurians Durieu ) is mentioned as the host plant of C. biolleyi , but this record is probably erroneous because this plant species belongs to the family Poaceae .
