The new species is named after the chocolate ‘MilkyWay’. Used as a noun in apposition. Diagnosis. Mallinella milkyway sp. nov. s hare features such as U-shaped epigynal plate, tear-shaped PVS, and tremendously lengthened insemination ducts with the members of the redimita-group. Within the redimita-group, males of M. milkyway sp. nov. are most similar to the males of M. redimita as both share flange-like RTA, bifurcated embolus, sharp apical ridge directed posteromesad and a triangular apico-retrolateral fold with a blunt apex but can be separated from it by the rami of the embolus with blunt apices (sharply pointed in M. redimita ) and lanceolate dorsal scutum (cf. Dankittipakul et al. 2012 : figs. 706–707 and Figs. 2A, 2F–H , 8B ). Females are also most similar to the females of M. redimata as both share U-shaped epigynal plate, and elongated insemination ducts but can be separated from it by globular spermathecae (truncated spermathecae in M. redimita ) (cf. Dankittipakul et al. 2012 : figs. 694–699, 701-703 and Figs. 2C–D , 7B–G , 9C–D ). Description. Male in alcohol ( holotype ; Fig. 2A ).
