In the Yunnan specimens, the structure is short and coiled, and lies wholly on the caudal side of the coxal processes, perhaps to some degree an artifact of the illustrations reflecting foreshortening; however, the cannula in Laotian males curves but does not coil and is much longer, extending

The number of the latter can also vary; it usually is three but occasionally there are four caused by division, near midlength, of the caudalmost branch into two equivalent subbranches that are closely appressed to each other. In one Laotian male, the left telopodite has four branches and the right, three.

, we believe the cannula may be the “functional” element that directly inseminates females particularly because it terminates freely and the telopodite lacks a prostatic groove. The telopodite is also firmly attached and stationary, whereas the cannula is movable at the articulation with the coxa as evidenced by how easily it is dislodged during dissection. In the introduction to his work, Zhang (1993) stated “seminal furrow (= prostatic groove) obscurely visible,” but it is not shown on his figures nor mentioned in the gonopodal characterization in the species description. Careful examination of the Laotian gonopods reveals no evidence of a prostatic groove, and we believe it is indeed absent. Without the groove and a connection between the cannula and telopodite, the most plausible method of spermatophore/ seminal fluid transfer seems to be by the cannula directly, which in the Laotian males is the longest gonopodal structure, could most easily contact the openings of the vasa deferentia to be “charged,” and subsequently penetrate the female cyphopods during copulation. Observing the gonopods

, it is evident that the body could be flexed and the cannulae “pushed” forward to contact the gonapophyses and cyphopods of females. If the cannulae are the “functional” element instead of the telopodite as in other callipodidans, this could be interpreted as a plesiomorphy, an early stage in gonopod development in which a “functional” telopodite is obviated by a more direct method of spermatophore transmittal that requires a less intricate structure. The presence on the 9th legs of the trochanteral lobe with short projections and an internal duct of some sort as evidenced by the central pore (
