50 P. Dolejš & M. Hanko to use the second palp sometime after the haematodocha of the first palp had collapsed. During this period, when ma- les were apparently doing ‘nothing’, perhaps the copulatory courtship occurred in relation to the cryptic female choice (e.g., Huber 1998, Peretti & Aisenberg 2015). Some males of Z. guerrerensis were observed having an obvious problem to insert their palps correctly. We call this behaviour ‘flubs’, despite some uncertainties existing about their definition and true meaning (e.g., Huber 1998, Barran- tes 2008, Sentenská et al. 2015). In our opinion, the flubs were apparently mistakes as was defined by Watson (1991) and further observed by Dolejš et al. (2012) and Toscano-Gadea & Costa (2016).Thus, the flubs observed by us are not regu- larly observed palpal scraping of the epigyne just before the palpal insertion. Zorocrates guerrerensis appeared to be both polyandrous and polygynous species. Among the Lycosoidea, the same characteristics is known for the pisaurids (Nitzsche 2011 and references therein), whereas lycosid females are mo- nandrous (Norton & Uetz 2005, Dolejš et al. 2012). Const- ruction of the first egg sac by Z. guerrerensis and the emerging of spiderlings from it were in identical time intervals as in T. radiata (Barrantes & Madrigal-Brenes 2008). Overall, very little is still known about the courtship and copulatory pattern of the zoropsids. The situation that some mating characteristics of Z. guerrerensis are more similar to T. perfuga and wolf spiders than to T. radiata is surprising be- cause it was expected that related species would have similar behaviour. When behavioural details of more species of Zo- ropsidae are known, they may be of some use for improving the phylogeny of Lycosoidea. Acknowledgements We are very much obliged to Jaromír Hajer for providing us with living spiderlings of Z. guerrerensis and Jiří Král for clarifying its biotope. We would like to thank Ivana Sýkorová for supervising the grammar-school-thesis of the second author. We also thank Pavel Just for technical help with the video. Finally, we are obliged to two anonymous reviewers for their corrections and helpful comments on the earlier draft.
