Megalopinus tangi Puthz, 2012

Megalopinus lapsus Mainda, 2022 syn. nov.

[= replacement name for M. modestus Puthz, 2021 nec M. modestus (Sharp, 1886) ]

Specimens examined: male holotype of M. tangi , photo provided by Dr. Liang Tang; male paratype of M. tangi , photo provided by SMNS; male holotype of M. lapsus ; two males, one female, ‘LAO, Phongsaly prov., 21°41’N 102°6’E, PHONGSALY env., 6.-17.v.2004, 1500m, Vít Kubáň leg.’ / ‘ Megalopinus tangi Puthz , det. Puthz 2013 ’, male specimens with aedeagus embedded in Euparal on a transparent platelet; female, ‘LAO, Phongsaly prov., 21°41-2’N 102°06-8’E, 28.v.-20.vi.2003, PHONGSALY env., 1500m, Vít Kubáň leg.’ / ‘ Megalopinus tangi Puthz , det. Puthz 2013 ’ (MHNB).

Note: The comparison of the elytra pattern and structures of tergites X of Megalopinus tangi Puthz, 2012 ( Puthz 2012: Fig. 50) and Megalopinus lapsus Mainda, 2022 ( Mainda 2022: Fig. 3A ) does not reveal any differences that go beyond intraspecific variability. The same applies to the aedeagi of M. tangi ( Puthz 2012: Fig. 84) and M. lapsus ( Puthz 2021: Fig. 4 ). The alleged differences in the shape of the internal sclerites cited by Puthz (2021) result from three-dimensional objects looking slightly different depending on their position in the dissection. The aedeagus figure by Puthz (2021) shows the shape of the sclerites much better than the figure by Puthz (2012).

Megalopinus tangi was described from China (Guangxi) and Thailand (Chiang Mai) . Puthz (2013) reported further specimens from northern Laos (Phongsaly Prov.) . The holotype of M. lapsus syn. nov. was also collected in northern Laos (Houaphanh Prov.) .
