Research on millipedes has taken off the last decade due to the increasing use of electron microscopes for morphological studies. With election microscopy, systematists can now clearly distinguish and identify millipede species based on details of structures other than the male copulatory organ. A new material of Ilodesmus margaritiferus, which has been originally described by Gervais in 1836, was recollected in Mt. Makiling during a terrestrial arthropod survey of the Hearst Philippines Biodiversity Expedition in 2011. 

Early this 2014, Facundo M. Labarque, Veverle D.A. San Juan, Ireneo L. Lit, Jr., and Charles E. Grisworld provided in their article "Redescription of the Flatbacked Millipede Ilodesmus margaritiferus (Gervais, 1836) (Diplopoda: Polydesmida: Platyrhacidae) from the Philippines." very detailed illustrations of the head, antennae, gnathochilarium, mandibles, body rings, spiracles, legs, gonopds and eggs. According to the authors, the morphological features are described for the family Platyrhacidae for the first time.
