Banyijima Flattie Karaops banyijima Crews, 2013

(after Crews 2023): The female of K. banyjima is somewhat similar to Karaops burbidgei by the location of the copulatory openings and the general shape of the structures of the endogyne. In K. banyjima, however, the copulatory openings are located in a depression that is m-shaped along the top margin and w-shaped along the bottom margin, the ducts connecting the spermathecae and the accessory bulbs are not twisted, and the spermathecae and accessory bulbs are highly sclerotized.

The male is most similar to Karaops nyangumarta, but the two species can be differentiated by the tegular lobe, the median apophysis, the conductor, and the dorsal retrolateral tibial apophysis (dRTA). In K. banyjima, the narrowing of the tegular lobe to the embolus is nearly midway from the basal and distal portions of the bulb. In K. nyangumarta, this point is in the basal third of the bulb. The median apophysis of K. banyjima has no spinules, and the median apophysis of K. nyangumarta has a dense array of spinules. The conductor of K. banyjima does not reach the retrolateral edge of the bulb, and the tip is directed laterally, whereas in K. nyangumarta, the conductor reaches the retrolateral side of the bulb, and the tip of the conductor is directed ventrally. The dRTA of K. banyjima is rather short and stout (but not like a little teapot), whereas that of K. nyangumarta is longer, narrower, and curved slightly ventrally. It is somewhat difficult to distinguish the two in life by the abdominal pattern, but K. nyangumarta males have more mottling dorsally on the abdomen.
