This is the first systematic treatment of the Diplommatinidae of Timor-Leste, the country that encompasses the eastern part of the island of Timor. Three diplommatinid species in two genera were recorded from the western part of the island in previous systematic literature. Based on 28 samples collected between 2010 and 2012 throughout Timor-Leste, we describe five additional species (Diplommatina atauroensis n. sp., Palaina ainaro n. sp., Palaina orelimo n. sp., Palaina tuba n. sp., and Palaina brandontrani n. sp.), raising the number of diplommatinid species on the island to eight. Two species previously described from West Timor (Diplommatina fluminis B. Rensch, 1931 and Palaina mutis Greke, 2017) were also recorded in Timor-Leste; both appear to be more widespread, the former also occurring on the neighbouring island of Sumba and possibly also on Flores, Bali and Java. However, all newly described species are known only from their type localities, all of which are on exposed limestone. They are deemed to be narrow range endemics that probably do not occur outside Timor-Leste.http://www.zoobank.org/urn:lsid:zoobank.org:pub:03796E39-003B-4CF1-87A0-DCB23D6AA396
