 Martarega chinai is widely distributed in northern South America, also occurring in the southeastern region of Brazil (Figure 13B). In spite of resembling M. membranacea in having a median longitudinal stripe bifurcated near the apex of hemelytra (Figure 5A,B) and similar right clasper (Figures 4C, 5D), M. chinai can be recognized by the format of the left clasper, which is distinct, with a longitudinal carina along its length (Figure 5E). The alleged “nodule” on ventral surface of male mesotrochanter (Figures 5C), which differentiates M. chinai from M. membranacea, is a group of short bristles as observed in M. gonostyla (Figure 8C). Females of this species can be distinguished from females of M. membranacea by their hemelytral process not extending to tip of membrane (Figure 5B). In female M. membranacea, the hemelytral process visibly reaches the apex of membrane (Figure 4B).
