Figure 6.Copulatory profile for Perochaeta orientalis, as described in Section 2 (Copulation). Horizontal bars in graph indicate point in time (X-axis) where then the particular behaviour (Y-axis) is performed. The profile begins from when the male mounts the female, and ends when they begin to separate (total time = 72m 30s).

Figure 4.Images of holotype (A, B) and drawing (C) from description for Perochaeta orientalis, male. A Image of habitus, lateral view B Image of hypopygium, dorsal view; red arrow pointing to the median protrusion on the surstylus C Drawing of abdominal posterior (lateral view) as reproduced from Duda (1926); red arrow 1 shows how illustration has fused the two setae into one, red arrow 2 shows how the drawing fails to display the median protrusion as seen in Fig. 1G.
