March 1833, Drège 3438 (lectotype P [P04256914] scan!, here designated; isolectotype K! [K000234579] fragment). Schizoglossum crassipes Moore (1902: 383) .

In the original description of Lagarinthus eustegioides Meyer (1837) only one locality is listed. When this locality is cross-referenced with the collections listed in Drège (1843: 54–55) the only collection that matches the taxon and locality is Drège 3438. As the specimen from P (only scan seen) is a more complete specimen when compared to the fragment at K, it is selected here as the lectotype.
