The first geophilid centipedes from Malesia: a new genus with two new species from Sumatra (Chilopoda, Geophilidae)

Abstract

A new genus Sundageophilus is here described for two new species of geophilid centipedes (Chilopoda: Geophilidae) from Sumatra, Indonesia. Both Sundageophilus bidentatus sp. n. and Sundageophilus poriger sp. n. feature a minute body size (less than 1 cm long with 31–35 pairs of legs), a similar structure of the maxillae, elongated forcipules, and few coxal organs. Sundageophilus bidentatus is unique among geophilids because the ultimate article of the forcipule is armed with two conspicuous denticles, one dorsal to the other, instead of a single one or none. The two species of Sundageophilus are the first genuine Geophilidae ever found in Malesia, and among the very few representatives of this family in the entire south-eastern Asia.

“…Taxonomic notes – The species was originally classified in the geophilid genus Brachygeophilus Brölemann, 1909 and its taxonomic position was not revised after that Brachygeophilus was synonymised under Geophilus Leach, 1814 (since Foddai et al 1995). The species was suspected to belong to Gonibregmatidae by Bonato et al (2016), but its taxonomic position cannot be resolved based on the published information. Luanganavarians Attems, 1953 Original description – Attems 1953: 143, figs 7–9.Other sources for morphology – none.Reported specimens – ≥2.Type locality – “Luang Prabang” [=Louangphabang, Laos].Geographical records – Laos: Louangphabang (Attems 1953). Taxonomic notes – The species was originally classified in Geophilidae in a distinct monotypic genus Luangana Attems, 1953, but it was suspected to belong to Gonibregmatidae by Bonato et al (2016).…”
