03F487FCF704762B909FFB6EF9C227BC.taxon	diagnosis	Diagnosis This species mostly resembles M. taiwanus, M. masamii, M. ogasawaraensis, M. morrisoni and M. palauensis in the shape of the median lobe, with subapical projections distinctly divided from the apex of the median lobe. It can be distinguished from the first four species by the left subapical projections curved outwardly, and from the last species by the robust apex of the median lobe.	en	Liu, Zhen-Hua, Jia, Feng-Long (2021): Descriptions of two new species of Mexico Spilman, 1972 from the Oriental region (Coleoptera: Limnichidae).

03F487FCF703762490B3FEDEFC9626A7.taxon	diagnosis	Diagnosis This species is similar to M. papuanus, M. litoralis, M. borneensis and M. baliensis in terms of the very simple median lobe without divided subapical projections. It can be easily distinguished from those species by median lobe distinctly expanded subapically. It can be further distinguished from M. papuanus and M. litoralis by the long apical setae on the lateral lobes and lateral lobes being shorter than half of median lobe, and from M. borneensis and M. baliensis by the more acuminate apex.	en	Liu, Zhen-Hua, Jia, Feng-Long (2021): Descriptions of two new species of Mexico Spilman, 1972 from the Oriental region (Coleoptera: Limnichidae).
