Ctenocolum colburni Kingsolver & Whitehead, 1974a . Holotype deposited in USNM , male: “ HOND ./ Cuyamel/ 17.VIII.1924 / MACarleton” [white label handwritten in black]; “ Lonchocarpus / pentaphyllus / (Poir.)

Note. Kingsolver & Whitehead (1974) indicated that the holotype and the eight paratypes are deposited in USNM . The holotype and the paratype received from USNM were examined and coincide with the description. Additional material. MEXICO : Veracruz: 2, Catemaco, 20.III.2001 ( DZUP ). Diagnosis. Ctenocolum colburni differs from all other species by the dorsum mostly covered with yellowish gray setae forming a “C” pattern on elytra and pronotum with sparse setae exposing the integument and forming a rounded area anteriorly ( Fig. 10 ). Redescription. BL: 2.5–3.05 mm ; BW: 1.6–2.3 mm . Integument. Dorsum mostly black. Antenna black and brown ( Figs. 10 , 55 ) or dark brown and brown. Pygidium black and reddish brown or black and rufous. Ventral region reddish brown and black. Front and middle femur and tibia pale brown and brown or darker; hind femur brown and black. Pubescence. Pronotum white, yellowish gray and black; sparse setae exposing the integument forming a rounded area on anterior region ( Fig. 10 ). Elytra strongly variegated with black, white and yellowish gray setae; yellowish gray setae forming a “C” pattern from basal to median region; interstria 3 without white setae ( Fig. 10 ). Pygidium white and yellowish gray, dense except on two basal, four lateral and one apical small areas with sparse setae; at median region a larger area with sparse setae ( Fig. 36 ). Ventral region white, pale yellow and pale brown ( Fig. 55 ). Head. Ocular sinus 0.2–0.3 mm ; ocular index 5.3–5.5; length of eyes in frontal view behind sinus 0.01-0.09 mm ( Fig. 24 ). Antenna serrate from antennomere 4. Frons with frontal carina ( Fig. 24 ). Prothorax. Pronotum with median gibbosity slightly elevated, not divided by longitudinal and transversal sulcus ( Fig. 55 ); lateral gibbosity slightly elevated; basal lobe without depression and slightly emarginated ( Fig. 10 ). Mesothorax and metathorax. Elytra, striae with punctures moderately impressed; less conspicuous teeth at base of striae 3 and 4; tooth of stria 4 closer to base of tooth of stria 3 than to anterior margin of elytra; stria 6 conspicuously impressed ( Fig. 10 ). Hind femur ( Fig. 68 ) on external ventral margin with toothed carina; without denticles above of external ventral margin; pecten with 6–7 teeth. Hind tibia ( Fig. 68 ) strongly emarginated beside mucro; lateral coronal denticles present. Abdomen. Pygidium longer than wide, oval, at median basal region with moderately impressed punctures ( Fig. 36 ). Male genitalia. Median lobe, ventral valve as long as wide, lateral margin concave on subapical region ( Fig. 80 ), basal margin strongly emarginated. Internal sac, lateral apex with short tuft of setae, hinge sclerite with inverted L-shape, long, extending through subapical region; subapical region with homogeneously distributed spicules; median and submedian regions with sparse lateral denticles, squamous sclerite with balloon-shape ( Fig. 80 ); basal region with homogeneously distributed spines and sparse denticles. Tegmen ( Fig. 92 ), lateral lobes separated by emargination about 0.7 times the length of lateral lobes; internal margin near end of emargination curved, forming a "U"; expanded at apex, about 4 times the smallest width on median region; without membranous projection at apex. Note. All specimens examined are males. Distribution. Neotropical region: Mexico (Veracruz), Guatemala (Chimaltenango), Honduras (Colón, Copán, El Paraíso), Costa Rica (Heredia). Host plants (Tables I–II). Papilionoideae : Lonchocarpus heptaphyllus (Poir.) DC. (= L. pentaphyllus (Poir.) DC.), L. purpureus Pittier , L. velutinus Benth. Note. Kingsolver & Whitehead (1974a) and Udayagiri & Wadhi (1989) quoted L. velutina , but according to the literature (http://www.catalogue of life.org / ) this name does not exist. We suspect that the spelling is wrong, and that the correct is L. velutinus .
