Group podagricus

Group crotonae: Kingsolver & Whitehead (1974a) : 291, 292 (distribution, host plant, taxonomy).

Included species: C. aquilus Albuquerque & Ribeiro-Costa sp. nov., C. biolleyi , C. colburni , C. martiale , C. milelo Albuquerque & Ribeiro-Costa sp. nov., C. podagricus , C. punctinotatus Albuquerque & Ribeiro-Costa sp. nov., C. pygospilotos Albuquerque & Ribeiro-Costa sp. nov., C. triangulatus Albuquerque & Ribeiro- Costa sp. nov.

Diagnosis. Pronotum with median gibbosity not divided by transversal sulcus, except C. aquilus Albuquerque & Ribeiro-Costa sp. nov.; lateral carina about half of pronotum, never reaching cervical sulcus. Hind femur with second tooth of pecten gradually increasing in size until middle and decreasing towards apex ( Figs. 66–74 ). Hind tibia with ventral carina projected on apical half; without row of denticles on outer surface; apex with lateral coronal tooth and strongly emarginated beside mucro ( Figs. 66–74 ); 1- tarsomere with lateral carina. Median lobe ( Figs. 6 , 79–86 ), ventral valve truncate apically; on subapical region with lateral margin concave; internal sac with squamous sclerite. Tegmen ( Figs. 91–98 ), lateral lobe truncated at apex; internal margin with thick setae, transverse directed towards middle.

Distribution. Neotropical region: Puerto Rico, Mexico (Sinaloa, Nayarit, Jalisco, Querétaro, Veracruz, Michoacán, Guerrero, Oaxaca, Chiapas, Campeche, Quintana Roo), Guatemala (Chimaltenango), El Salvador (San Salvador, La Unión), Honduras (Colón, Copán, El Paraíso), Costa Rica (Guanacaste, Heredia, Puntarenas, San Jose), Venezuela (Distrito Capital), Trinidad e Tobago ( Tobago, Trinidad), Guyana, Ecuador, Brazil (Mato Grosso, Paraná).

New records: United States Virgin Islands, Jamaica (Saint James), Colombia, Ecuador (Guayas*), Peru (Junin), Bolivia (Santa Cruz), Brazil (São Paulo).

Host plants (Table I–II). Papilionoideae : Lonchocarpus sp., L. costaricensis (Donn. Sm.) Pittier. , L. constrictus Pittier , L. eriocarinalis Micheli. , L. heptaphyllus (Poir.) DC., L. hondurensis Benth. , L. margaritensis Pittier , L. minimiflorus Donn. Sm. , L. nitidus (Vogel) Benth. , L. parviflorus Benth. , L. purpureus Pittier , L. rugosus Benth. , L. sericeus (Poir.) DC., L. velutinus Benth. , Muellera sp. (= Bergeronia sp.), Piscidia carthagenensis Jacq. , Piscidia piscipula (L.) Sarg. (= P. erythrina L.).

Caesalpinioideae : Peltophorum dasyrrhachis (Miq.) Kurz.

New records: Caesalpinioideae : Bauhinia glabra Jacq. Papilionoideae : Lonchocarpus guillemineanus (Tul.) Malme , L. muehlbergianus Hassl.

Notes. According to Kingsolver & Whitehead (1974a), the record in Peltophorum dasyrrhachis is dubious. Larvae of this group are known to feed on seeds of Muellera (= Bergeronia ), Lonchocarpus , and Piscidia , therefore the first genus not have been associated at species level of Ctenocolum ( Kingsolver & Whitehead 1974a). The genus Bauhinia is recorded here for the first time as host plant for the group podagricus and to the genus Ctenocolum .

Comparative notes. Kingsolver & Whitehead (1974a) mentioned that the group podagricus probably is natural but the relationships among its component species are not clear. According to the authors ( Kingsolver & Whitehead 1974a), Ctenocolum colburni is the most distinct and C. podagricus , C. biolleyi and C. martiale are probably closer to each other by sharing the increased basal displacement of teeth on stria 4 of elytra; this basal displacement is more pronounced in C. biolleyi and C. martiale , may indicate that they are more closely related to each other than to any of the others. We observed that C. aquilus Albuquerque & Ribeiro-Costa sp. nov., C. milelo Albuquerque & Ribeiro-Costa sp. nov. and C. podagricus share the general pubescence pattern on the dorsum, a character that differentiates these species from all others ( Figs. 8, 13, 14 ). By contrast, Ctenocolum punctinotatus Albuquerque & Ribeiro-Costa sp. nov. and C. pygospilotos Albuquerque & Ribeiro-Costa sp. nov. share deeply impressed punctures in the striae of the elytra and a similar general pubescence pattern, with yellowish gray and white setae that separate them from all others ( Figs. 15, 16 ).
