Medeopteryx Ballantyne in Ballantyne & Lambkin 2013: 76 .

Type species: Pteroptyx effulgens Ballantyne designated by Ballantyne & Lambkin 2013: 76.

Diagnosis. Ballantyne & Lambkin (2013) addressed species having deflexed elytral apices in the male and proposed three genera (two of which were new): 1. Medeopteryx Ballantyne was based mainly on New Guinean bent-winged fireflies formerly assigned to Pteroptyx , and was proposed for New Guinean and Australian species with an entire LO in V7, the posterior margin of which is trisinuate with PLP no longer or wider than the MPP. It has no MFC and no bulbous paraprocts at the sides of the aedeagal sheath. All but two species have deflexed elytral apices, with a uniform colouration of orange pronota and very dark brown elytra in all but Med. tarsalis . All but two species, both with deflexed elytral apices, are known to have well defined flanges on the ventral surface of T8 (the species, hanedai and torricelliensis, were not investigated for this feature). 2. Pteroptyx Olivier s. str. was restricted to 12 S. E. Asian species with males having bipartite LO in V7, bulbous paraprocts, an MFC, deflexed elytral apices and PLP usually no longer or wider than the MPP. Most are pale brownish yellow with dark tipped elytral apices. Ballantyne et al. (2015) expanded this definition to include two species without deflexed elytral apices and having entire LO in V7, and Jusoh et al. (2018) described the type species, Luciola testacea , from a syntype series. 3. Trisinuata Ballantyne males have bipartite LO in V7, no bulbous paraprocts nor an MFC, deflexed elytral apices absent in three species, and PLP in some species much wider and longer than the MPP.

Yiu (2017) recorded Med. hongkongensis from Hong Kong. Here we expand Medeopteryx to include further records of the genus from west of the island of New Guinea, with three species providing new records of the genus: Med. fraseri Nada sp. nov. from Malaysia, Med. semimarginata comb. nov. from Sulawesi the largest representative, and Med. timida comb. nov. from Vietnam. Nak-eiam’s unpublished PhD thesis indicated that undescribed specimens he identified as Medeopteryx and Trisinuata could be found in Thailand.
