Abstract
Chironomus samoensis, as currently recognised, is not a single species but a complex of more or less closely related species. C. samoensis Edwards 1928 is redescribed from additional material, and considered to occur only in the Pacific region. Reasons for excluding material from other areas are given. C. flaviplumus Tokunaga 1940 is confirmed as the correct name for the Japanese material, the Indian material described by Chattopadhyay et al. (1991) is given the new name C. indiaensis, and new names are required for material from Australia and additional species from India.
Highlights
Chironomus samoensis Edwards 1928 was originally described from Samoa, American Samoa (Pago Pago) and Tonga
One important feature is the superior volsella (SV) of the male, which Edwards compares to the SV figured for C. imberbis (Kieffer 1917), as well as to other species such as C. dorsalis, and C. hawaiiensis, which all have a superior volsella (SV) of the D type (Strenzke 1959)
An important character is the relative proportions of the fore leg, the tarsi, as Tokunaga (1964) notes that the Ta4 of specimens he assigned to C. samoensis was unusually long
