New long-legged flies from mangroves on Pulau Ubin (Singapore) (Insecta: Diptera: Dolichopodidae) Author Grootaert, Patrick Author Velde, Author Isabella Van de text Raffles Bulletin of Zoology 2024 2024-09-19 72 303 323 journal article 10.26107/RBZ-2024-0025 2345-7600 14683054 079CC651-8D4D-4B95-B022-388B2FA51FE2 Genus Protomedetera Tang, Yang & Grootaert, 2018 Type species. Protomedetera singaporensis Grootaert & Tang, 2018 (in Tang et al., 2018 ) Protomedetera comprise small species with a body length less than or at most 2 mm . The genus is quite rare in Singapore and up until now, only two species were known from Singapore . The type species of the genus, Protomedetera singaporensis Grootaert & Tang, 2018 (in Tang et al., 2018 ) was described from a single male found in the swamp forest at Nee Soon ( Singapore ). A second species P. glabra Tang et al., 2018 , found only in anthropogenic habitats, is more common in Singapore . This species was attributed to the genus Protomedetera , but it has a different morphology and should probably be attributed to another genus. The postpedicel does not bear long apical bristles and the position of the male terminalia on the abdomen is different. P. glabra was originally described from Papua New Guinea and the specimens found in Singapore were considered conspecific. Although the male terminalia of the specimens from Papua New Guinea and those from Singapore are similar, they are distinctly different in other characteristics and hence the taxonomy of this species group needs revision.
