Group tuberculatum

Group tuberculatum: Kingsolver & Whitehead (1974a) : 287, 288 (distribution, host plant, taxonomy).

Included species: C. acapulcensis , C. janzeni , C. salvini and C. tuberculatum .

Diagnosis. Pronotum with median gibbosity divided by transversal sulcus; lateral carina reaching cervical sulcus. Hind femur with second tooth of pecten regular in profile until apex ( Figs. 75–78 View FIGURES 72 – 76 View FIGURES 77 – 78 ). Hind tibia with ventral carina projected on apical third; with row of denticles in the outer surface; apex without lateral coronal tooth and slightly or moderately emarginated beside mucro ( Figs. 75–78 View FIGURES 72 – 76 View FIGURES 77 – 78 ); 1-tarsomere without lateral carina. Median lobe ( Figs. 5 View FIGURES 1 – 7 , 87–90 View FIGURES 85 – 90 ), ventral valve acute apically; subapical region with lateral margin usually straight; internal sac with smooth sclerite. Tegmen ( Figs. 7 View FIGURES 1 – 7 , 99–102 View FIGURES 91 – 99 View FIGURES 100 – 102 ), lateral lobe rounded at apex; internal margin with thin setae, longitudinal or slightly inclined, never toward the middle.

Distribution. Nearctic region: Mexico (Sonora, Tamaulipas). Neotropical region: Mexico (Sinaloa, Nayarit, San Luis Potosi, Jalisco, Veracruz, Guerrero, Morelos, Oaxaca, Yucatán), Guatemala (Sacatepéquez, Escuintla), Honduras (Olancho), Costa Rica (Puntarenas), Panama, Venezuela (Aragua).

New record: Costa Rica (Guanacaste).

Host plants (Tables I–II). Papilionoideae : Dalbergia retusa Hemsl. , Lonchocarpus sp., L. eriocarinalis Micheli. , L. longistylus Pittier , L. minimiflorus Donn. Sm. , L. nitidus (Vogel) Benth. , L. parviflorus Benth. , L. rugosus Benth. , Piscidia sp., P. grandifolia (Donn. Sm.) I. M. Johnst. , P. mollis Rose , P. carthagenensis Jacq.

New record: Papilionoideae : L. emarginatus Pittier.

Comparative notes. Kingsolver & Whitehead (1974a) remarked that a large, symmetric and complex sclerite on the male genitalia is putative evidence that the group tuberculatum is probably natural. However, the relationship among its species is not clear. Is possible that synapomorphies occur between the species C. acapulcensis and C. salvini (sclerite of male genitalia simplified) and between C. acapulsensis and C. janzeni (eye with sexual dimorphism) ( Kingsolver & Whitehead 1974a).

In this review, we have noticed that C. janzeni and C. salvini are probably closer to each other because they share denticles above the external ventral margin on hind femur ( Figs. 76 View FIGURES 72 – 76 , 77 View FIGURES 77 – 78 ), a character that is unique to these two species.
