Note. Kingsolver & Whitehead (1974) quoted the holotype is deposited in the USNM and the thirteen paratypes in the CNC and USNM. The holotype and the eight paratypes received from USNM were examined and coincide with the description.
Additional material. MEXICO: Nayarit: 2, 5 mi. S Rosamorada, 04.III.1979, reared seeds 600-79, C. D. Johnson col. (TAMU); 1, same information (DZUP). Jalisco: 1, Chamela, 31.I.1980, A.

Diagnosis. Ctenocolum martiale is different from C. milelo, C. podagricus and C. triangulatus by having striae 3 and 4 of elytra with conspicuous teeth at base. This species differs from all other species mainly by the male genitalia with the internal sac bilobate, elongate with dense spines and the presence of a hollow sclerite (Fig. 81).
Redescription. BL: 2.6–4.4 mm; BW: 2.0– 2.6 mm.
Integument. Dorsum in general black and reddish brown. Antenna brown and dark brown, sometimes first 3 antennomeres paler (Figs. 11, 12). Pygidium reddish brown or reddish brown and black or rufous. Ventral region reddish brown and black sometimes adding brown. Front and middle femur and tibia variegated from pale brown to dark brown and reddish brown; hind femur reddish brown and from dark brown to black.
Pubescence. Pronotum brown, white and black; sparse setae exposing the integument forming an oval, wide area from anterior to posterior region divided or not by transversal and longitudinal strip or only by transversal strip of denser setae and on each lateral region one small area (Figs. 11, 12). Elytra slightly or strongly variegated with brown, black and white setae; interstria 3 with white or yellowish gray setae forming a short dense or sparse strip at base and at submedian region with short dense or sparse strip of white setae (Figs. 11, 12). Pygidium densely white and yellowish gray, some females white and brown (Fig. 48), except on two basal, four lateral, one apical small areas with sparse setae and on median region a larger area with sparse setae (Figs. 37, 48). Ventral region dark brown and white (Fig. 56).
Head. Ocular sinus 0.2–0.3 mm; ocular index 4.2–5.4; length of eyes in frontal view behind sinus 0.07–0.10 mm (Fig. 25). Antenna serrate from antennomere 3-10 in male and from 4-10 in female. Frons with frontal carina (Fig. 25).
Prothorax. Pronotum with median gibbosity slightly elevated, not divided by longitudinal and transversal sulcus (Fig. 56); lateral gibbosity slightly to moderately elevated; basal lobe with depression and slightly or strongly emarginated (Figs. 11, 12).
Mesothorax and metathorax. Elytra, striae with punctures moderately impressed; conspicuous teeth at base of striae 3 and 4 (Fig. 11); tooth of stria 4 closer to base of tooth of stria 3 than to anterior margin of elytra; stria 6 conspicuously impressed. Hind femur (Fig. 69) on external ventral margin with toothed carina; without denticles above of external ventral margin; pecten with 8–10 teeth. Hind tibia (Fig. 69) strongly emarginated beside mucro; lateral coronal denticles present.
Abdomen. Pygidium of female subequal, subtriangular (Fig. 48), of male longer than wide, oval (Fig. 37), at median basal region with moderately impressed punctures.
Male genitalia. Median lobe, ventral valve wider than long, lateral margin concave on subapical region (Fig. 81), basal margin slightly emarginated. Internal sac, lateral apex with short tuft of setae, hinge sclerite similar to stick, long, extending through subapical region; subapical and median regions with homogeneously distributed spicules, at median region dense spicules in lateral strip; submedian region with spicules and squamous hollow sclerite (Fig. 81); basal region bilobate elongate and with dense spines. Tegmen (Fig. 93), lateral lobes separated by emargination about 0.7 times the length of lateral lobes; internal margin near end of emargination straight, forming a “V”; expanded at apex, about 4 times the smallest width on median region; without membranous projection at apex.
Note. Kingsolver & Whitehead (1974a) remarked that the pubescence of C. martiale is sexually dimorphic dorsally. Because we studied more specimens than the authors (Kingsolver & Whitehead 1974a), it was possible to conclude that the pubescence color pattern on the dorsum corresponds to intraspecific variation (Figs. 11,12).
Distribution. Neotropical region: Mexico (Nayarit, Jalisco, Veracruz, Michoacán, Guerrero, Oaxaca), Trinidad and Tobago (Trinidad).
Host plants (Tables I–II). Papilionoideae: Lonchocarpus constrictus Pittier, L. eriocarinalis Micheli., L. sericeus (Poir.) DC. (= L. cruentus Lundell).
