Material examined. Four paratypes (3 females and 1 male) preserved in 70% ethanol and mounted on slides by the authors, Fertőújlak (Hungary), position N 47°40'58" E 16°50'37", deposited at the US, 9.iv.1999, G. Traser leg. Seven topotypic specimens (4 males and 3 females) on slides deposited at the US, 14.vii.2017, D. Winkler leg.GoogleMaps 

Remarks. Specimens from the type series preserved in alcohol were in excellent conditions, with clearly visible chaetotacic characters. All specimens studied have the same morphology and chaetotaxy and match the description of Traser (2000), but with the following differences: Dorsal head macrochaetae formula A 0 A 2a A 2 A 3 Pa 5; interocular chaetotaxy with chaetae s, t, p, q and 2‒3 intraocular scales ( Fig. 1 View Figure ). Also all characters, except the absence of dorsal cephalic macrochaeta S3, match the description done for L. florae  sp. nov. (see Figures 12 – 33View FIGURES 12–17View FIGURES 18–19View FIGURES 20–22View FIGURES 23–24View FIGURES 25–27View FIGURES 28–33).

Discussion. Dorsal cephalic macrochaetae formula of L. arrabonicus  was described following RST system as R 0 R 1 R 2 R 3 P o ( Traser 2000). In the original description ( Traser 2000: Figure 2 View Figure ) the illustration of dorsal head chaetotaxy clearly shows that R 1 is actually R 1s, and R 3 is actually R 2 so the macrochaetae formula actually corresponds to the AMS scheme A 0 A 2a A 2 A 3 Pa 5. In all specimens we have studied this formula is also A 0 A 2a A 2 A 3 Pa 5. The original description erroneously missed interocular chaeta q ( Traser 2000: Figure 3), which is in fact present both in specimens of the type series, as well as in all other studied specimens from various locations.
