Planetella subterranea ( Kieffer & Trotter, 1904)

Pseudhormomyia subterranea Kieffer & Trotter,1904: 65 . Type locality:

Italy, Avellino.

Type material. Lost (see GAGN Ḗ & JAsCHHOF 2021).

Comments. The original description is without figures. Female is compared in table with P. granifex . In P. subterranea , the empodium is stated as longer than half of the claw (shorter in P. granifex ); 3 rd palpomere as narrowing in basal half, then the same to the end; flagellomere with two whorls of setae. In all other respects, as KIEFFER & TROTTER (1904) stated, these two species are identical, except in the shape of spatula. Galls were found on Carex divulsa , subterranean, similar to P. granifex . Collected in Avellino ( Italy). Subsequent figure of the male terminalia in KIEFFER (1913) indicates that this species is very similar or perhaps identical with P. granifex . Considering the possible existence of several cryptic species related to P. granifex , this species is left here as unrecognized.
