Allogalumna quadrimaculata ( Mahunka, 1988) comb. nov.

( Figs 4–5 )

The species Pergalumna quadrimaculata was described by Mahunka (1988) from Sabah, Malaysia. However, the original description (p. 887) has no information on presence or absence of lamellar and sublamellar lines, and the figures (Figs 131–133; p. 886) also do not allow understanding these structures. Subías (2004) included this species in the genus Allogalumna Grandjean, 1936 without giving any reason. Therefore, we studied the morphology of paratypes of P. quadrimaculata and found lamellar lines absent, but sublamellar lines present, curving backwards in this species. Hence, based on our research and generic diagnosis of Allogalumna (see Ermilov et al. 2013), we propose the following new combination: Allogalumna quadrimaculata ( Mahunka, 1988) comb. nov.
