Gargaphia magna new species 



Head small, black, with frontal spines all short, about the length of the 

 second antennal segment. Basal spines not protruding noticeably in front of 

 hood, more or less decumbent. First three antennal segments dark reddish 

 brown. Basal segment long and very dark. Third segment lighter towards 

 apex. Fourth black except at base. Hairs on antennae very short and fine. 

 Pronotal hood slightly more than twice as long as broad and distinctly higher 

 than median carina. Nervure on crest of hood darkened. Pronotum black, 

 punctate. Parallel carinae normal, rather low and wide apart. Lateral 

 membranous margins rounding, with three rows of areoles, nervures light 

 brown, margin dark brown. Elytra with four rows of areoles in costal area 

 at its greatest width. Subcostal area with four rows and raised to apex of 

 elytra. Nervures of membranous portions not hairy. Three transverse 

 oblique nervures of costal area black, also nervures towards apex of elytra 

 darkened. Areoles of the apical third of the elytra smoky except those of 

 costal area. Legs dark brown. Length, about 5 mm.
