Depth range From less than 2 m to 14 m depth. [details]
Diagnosis A moderate-sized gonochoristic Pseudopolydora species inhabiting mud tubes in soft bottoms. Body pigmentation absent. Prostomium rounded anteriorly. Four black eyes present. Caruncle reaching end of segment 4. Median antenna present on caruncle. Segment 1 with winged capillary neurochaetae. Anterior row of notochaetae on segments from 7 to 19 pennoned capillaries with shortly pointed main stem and enlarged semicircular limbation tapering to a long tip. Segment 5 slightly modified; two kinds of major spines arranged in a straight oblique or in almost a vertical J-shaped double row. Pygidium a small disc with dorsal gap. Glandular pouches from segment 1, single throughout. [details]
Distribution West Pacific Ocean, Taiwan: coasts of East and South China seas. [details]
Etymology The specific epithet vexillosa, feminine of the New Latin adjective vexillosus and meaning 'flag-like' or 'pennoned', refers to the characteristic shape of the modified notochaetae in the middle segments of the species. [details]
Habitat Inhabits mud tubes in soft bottoms of brackish-water environments. [details]
Status Re-validated. In Radashevsky et al (2020) specimens identified from Nha Trang Bay, Vietnam are molecularly distinct but closely related to P. paucibranchiata. However, these specimens are not from the type locality, which is Taiwan. Radashevsky et al (2020) nevertheless regards P. vexillosa as valid [details]
Type locality West Pacific Ocean, South China Sea, Taiwan, Tainan County, Tsengwen River estuary (23º04'N, 120º05'E), less than 2 m depth, mud or fine sand. [details]
