| abstract | Limnesia undulatoides spec. nov. is split off from Limnesia undulata. The morphological resemblance between the two species is close, but the dimensions of L. undulatoides are much larger than those of L. undulata. Moreover, the shape of the genital acetabula differs clearly. The colour of the newly described species is red, instead of yellowish as in L. undulata. In addition to that, there are differences between the life cycles of the two species. In L. undulatoides larvae hatch from the eggs, in L. undulata eggs develop into nymphs. From literature data it is obvious that in a few cases illustrations and/or text are dealing with L. undulatoides instead of L. undulata. When correcting for wrong identifications, L. undulatoides shows a Western Palaearctic distribution pattern. |
