Euphoria pulchella Species-Group

(Appendix 3: Plate 4p–y View Plate 4 )

Species in the pulchella species-group have a clypeus with the apex and lateral margins not raised, pronotal sides generally strongly angulate, protibiae not sexually dimorphic, and elytral striae composed mostly of deep grooves.

Composition. Four species are included in this group: Euphoria basalis (Gory and Percheron) , E. canaliculata Orozco , new species, E. diminuta Orozco , new species, and E. pulchella (Gory and Percheron) .

Natural History. Euphoria pulchella is the only species in the group that has been found associated with ants.

KEY TO THE SPECIES OF THE PULCHELLA SPECIES- GROUP

1. Clypeal apex strongly attenuate ( Fig. 52b View Fig ). Body surface frequently with cretaceous markings ( Fig. 52a, e View Fig ) ................................. .... E. pulchella (Gory and Percheron) (p. 90)

1′. Clypeus subrectangular. Body surface without cretaceous markings...............................2

2. Mesometasternal process wide, weakly compressed laterally. Elytra with 2 bright yellowish bands extending toward suture from the sides ( Fig. 49a, d View Fig ). Male abdomen strongly concave in lateral view................................. ... E. basalis (Gory and Percheron) (p. 86)

2′. Mesometasternal process moderately to strongly compressed laterally. Elytra color pattern not as above. Male abdomen weakly convex in lateral view..................................3

3. Antennal club shorter than stem in both sexes. Scutellum densely punctate basally; punctures moderate in size, lunulate to irregular. Mesometasternal process strongly compressed laterally............................................................ .... E. canaliculata Orozco , new species (p. 88)

3′. Antennal club as long as stem in males, shorter in females. Scutellum impunctate or with small, round punctures basally. Mesometasternal process weakly compressed laterally ............... ...... E. diminuta Orozco , new species (p. 89)

CLAVE PARA LAS ESPECIES DEL GRUPO PULCHELLA

1. Ápice clipeal fuertemente atenuado ( Fig. 52b View Fig ). Dorso frecuentemente con maculas cretáceas ( Fig. 52a, e View Fig )........................................................ ...... E. pulchella (Gory y Percheron) (p. 90)

1′. Clípeo subrectangular. Dorso sin máculas cretáceas........................................................2

2. Proceso mesometasternal ancho, levemente comprimido lateralmente. Élitros con 2 bandas amarillas brillantes extendiéndose desde los lados hacia la sutura ( Fig. 49a, d View Fig ). Abdomen de los machos en vista lateral fuertemente cóncavo ............ E. basalis (Gory y Percheron) (p. 86)

2′. Proceso mesometasternal moderada o fuertemente comprimido lateralmente. Patrón de coloración elitral no como la anterior. Abdomen de los machos en vista lateral levemente convexo.....3

3. Maza antenal en ambos sexos más corta que el resto de los segmentos antenales. Escutelo densamente punteado basalmente; punteaduras medianas en tamaño, lunuladas a irregulares en forma. Proceso mesometasternal fuertemente comprimido lateralmente......... E. canaliculata Orozco , especie nueva (p. 88)

3′. Maza antenal en machos tan larga como el resto de los segmentos, más corta en hembras. Escutelo sin punteaduras o con pequeñas punteaduras redondas en la base. Proceso mesometasternal levemente comprimido lateralmente ..... E. diminuta Orozco , especie nueva (p. 89)
