Euphoria inda Species-Group

(Appendix 3: Plate 5a–d )

Species in the inda species-group are distinguished by the broad clypeus, labium thickened anteriorly, emarginate pronotal base, irregularly shaped areas on each side of midline impunctate and glabrous, and distinct male genitalia ( Figs. 53c , 54c ).

Composition. Two species are included in this group: E. hirtipes Horn and E. inda (L.).

Natural History. Both adults and larvae have been found associated with ants of the genus Formica , but they are also known to develop independently.

KEY TO THE SPECIES OF THE INDA SPECIES- GROUP

1. Antennal club shorter than stem in both sexes. Protibiae robust, medial and basal teeth closer to each other than to apical tooth. Elytra shiny, mostly yellowish brown, black markings limited to sutural and posterior area ( Fig. 53a ). Males with dense fringe of setae on metatibiae.......... E. hirtipes Horn (p. 92)

1′. Antennal club longer than stem in males, shorter in females. Protibiae slender, teeth equidistant. Elytra tomentous (rarely shiny), with black markings distributed throughout entire surface ( Fig. 54a, d ). Males without dense fringe of setae on metatibiae................ ...................................... E. inda (L.) (p. 93)

CLAVE PARA LAS ESPECIES DEL GRUPO INDA

1. Maza antenal en ambos sexos más corta que el resto de los segmentos antenales. Protibias robustas, dientes basales y mediales más cercanos entre ellos que al diente apical. Élitros brillantes, café amarillentos en su mayoría, marcas negras solo en la región sutural y posterior ( Fig. 53a ). Machos con un grupo denso de setas en la metatibia..... .............................. E. hirtipes Horn (p. 92)

1′. Maza antenal en los machos más larga que el resto de los segmentos antenales, más corta en las hembras. Protibias delgadas, dientes equidistantes. Élitros tomentosos (raramente brillantes), con marcas negras distribuidas sobre toda la superficie ( Fig. 54a, d ). Machos sin grupo denso de setas en la metatibia ........ ....................................... E. inda (L.) (p. 93)
