Marilia lata Ulmer 1926

Marilia lata Ulmer 1926: 91 A 5 (1925), 68–70; figs. 53–56. Type locality: China ( Guang-dong )

Remarks. We have not seen specimens of this species. It apparently is similar to Marilia parallela . The original drawings by Ulmer (1926) for Marilia lata are very simple, but evidently the genitalia of M. lata differ from those of Marilia parallela by the following characters: (1) The lateromedian apical lobe on each side of segment IX is produced at 1/3 distance from the dorsal margin of segment IX, such that the distal end of the coxopodite of each inferior appendage reaches the level of the lateromedian apical lobe; (2) tergum X is not divided apically, and (3) its length is 2 times its height in lateral view. However, in M. parallela , the lateromedian apical lobe is produced at mid distance from the dorsal margin of segment IX, such that the distal end of the coxopodite of each inferior appendage far surpasses the level of the lateromedian apical lobe ( Fig. 6A ); tergum X is divided apically ( Fig. 6B ), and its length is 1.5 times its height in lateral view ( Fig. 6A ).

Distribution. Oriental Biogeographic Region, southern China (Guang-dong).
