Remarks

The illustrations provided by González-Sponga (1992) of the two species are remarkably similar; although it was not possible for us to examine the holotype of Forfexia marmorata , we examined abundant material collected from the type locality (topotypes), sufficient to justify the synonymy here proposed comparing with the types of Szczurekia dianae ( Figure 6 ). Besides, slight variations can be observed in the pattern of dorsal scutum spots ( Figure 6 (d,e)).

González-Sponga (1992) assigned a male ‘ holotype ’ (MAGS 111a) and a female ‘ paratype ’ (MAGS 111b) in the original description of Szczurekia dianae ; however, they were not identified amidst the type series, which are all stored together as syntypes. Here we assign the only dissected male as a lectotype and the remaining individuals as paralectotypes.

González-Sponga (1992) assigned letters ‘ a ’ and ‘ b ’ to the holotype and paratypes in the same lot. However, these designations do not mean that they were physically separated. Therefore, they are actually syntypes, incorrectly called ‘ holotype ’ and ‘ paratype ’.

It is highly probable that the only male dissected in MAGS 111 was also illustrated in the original description, and therefore it is here chosen as lectotype (ICZN Recommendation 74B). The same situation applies for the species N. petraeı N. punctataı N. virginis and N. yaracuyana .
