Lepidocyrtus arrabonicus Traser, 2000

Fig. 1 , Tab 1

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.

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 A0A2a A2A3Pa5; interocular chaetotaxy with chaetae s, t, p, q and 2‒3 intraocular scales ( Fig. 1 ). Also all characters, except the absence of dorsal cephalic macrochaeta S3, match the description done for L. florae sp. nov. (see Figures 12 – 33 ).

Discussion. Dorsal cephalic macrochaetae formula of L. arrabonicus was described following RST system as R0R1R2R3P o ( Traser 2000). In the original description ( Traser 2000: Figure 2 ) the illustration of dorsal head chaetotaxy clearly shows that R1 is actually R1s, and R3 is actually R2 so the macrochaetae formula actually corresponds to the AMS scheme A0A2a A2A3Pa5. In all specimens we have studied this formula is also A0A2a A2A3Pa5. 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.
