Diagnosis of larva.
The larva of new species is morphologically very similar to G. (G.) cylindricollis Reitter, 1889, but can be distinguished from it by the following characters: (1) lateral margins of the head with dense long setae (lateral margins of the head with sparse long setae in G. cylindricollis ); (2) mentum with two long setae on the side of the posterior margin and submentum with eight setae on located in the middle, posteriorly (mentum with four long setae on the side of the posterior margin and submentum with five setae in the posterior part of the center in G. cylindricollis ).
The larva of new species is morphologically very similar to G. (G.) felicitana but can be distinguished from the latter by the following characters: (1) lateral margins of the head with dense, long setae ( G. (G.) felicitana with sparse, long setae); (2) terga I-VIII with four pairs of long setae, two anterior pairs and two posterior pairs ( G. (G.) felicitana with six pairs of long setae, three anterior pairs and three posterior pairs); (3) frons with eight setae, two on upper margin, six on apex ( G. (G.) felicitana with eight setae, two on upper margin, two at center, and four at posterior margin in); (4) apex of antennomere III without long setae ( G. (G.) felicitana with one long seta at the apex); (5) side posterior margin of mentum with two long setae and middle of submentum with eight setae posteriorly ( G. (G.) felicitana with mentum and submentum both with 10 setae).
