The male of this species can be separated from that of J. mihun by the absence of a small, triangular denticle on the dorsal surface of the conductor (Figure 10 A cf. 10 D). However, we have a private notion that the boundary between these two species is vague and J. thakek comb. nov. is possibly a junior synonym of J. mihun. Much larger samples would be needed to corroborate these slight differences as species-specific rather than intraspecific variation because more material recently obtained suggests that J. mihun has relatively broad distribution covering northern and north-eastern parts of Thailand (and most likely extending eastwards to Laos where J. thakek comb. nov. was collected).</p> <p>Distribution</p> <p>Known only from the type locality, Khammouan Province, Laos.</p></div> 	http://treatment.plazi.org/id/EC2A175AFFBBFF8BAFFAD186FCA39DBC	Public Domain	No known copyright restrictions apply.

In comparison, in J. schwendingeri comb. nov. the conductor is narrower and its sharply pointed apex is abruptly bent (Figure 4 A, C), the tegulum and the distal RTA are significantly smaller. Females can be distinguished by the rather simple internal genitalia, the ID of which consists of circular proximal ducts, the more convoluted ID, and the poorly defined spermathecae (Figure 8 G cf. 8 F).</p> <p>Etymology</p> <p>The specific epithet is derived from Latin adjective (lunulatus = crescent-shaped), referring to the lamina-shaped conductor on the male palp.</p> <p>Description</p> <p>Male (holotype).
