New Afrotropical species of Tenuopus Curran, 1924 (Diptera: Dolichopodidae)

the genus are now known. T. comorensis is the fifth dolichopodid species discovered on the Comoros, with all the species being Island endemics. Material cited in this work is housed at the Natal Museum, Pietermaritzburg, Kwa-Zulu Natal, South Africa (NMSA) and Zoologische Staatssammlung, München, Germany (ZSM). Specimens have been studied and photographed with a ZEISS Discovery V-12 stereo microscope and an AxioCam MRc5 camera. Genitalia preparations have been photographed with a ZEISS Axiostar stereo microscope and an AxioCam ICc3 camera. Morphological terminology and abbreviations follow Cumming and Wood [2017], and Grichanov, Brooks [2017]. The relative lengths of the antennomeres and podomeres should be regarded as representative ratios and not measurements. Body length is measured from the base of the antenna to the tip of abdominal segment 6. Wing length is measured from the base to the wing apex. The figures showing the hypopygium in lateral view are oriented as it appears in the intact specimens, with the morphologically ventral surface of the genitalia facing upwards, dorsal surface downwards, anterior end facing left and posterior end facing right.
