Planetella rosenhaueri ( Rübsaamen, 1892)

Hormomyia rosenhaueri Rübsaamen, 1892 d: 394 . Type locality: Germany, Berlin. Type material. HOLOTYPE: ♀, Berlin, 28.iii.1896 (coll. ZMHB Berlin, No. 642), examined.

Comments. The original description includes the information that the gall was found on Carex acuta in the collection of Rosenhauer, somewhat similar to that of Planetella fischeri (as Hormomyia fischeri ). Very similar galls are said to be induced on different host plant species by related species. It is also stated there that there are similar galls on Carex arenaria and C. rostrata in the herbarium of prof. P. Magnus .The larvae taken from the galls are reported as quite different. The adult female is described as having antennae with 2 + 20 segments. Unrecognized species.

RȖBsAAMEN (1917) created a separate genus for this species, Paurosphondylus , stating that it has all the flagellomeres uninodal. Most probably, he meant only the females, because no male specimen is present in the type series.
