Among the material examined</p><p>was one male specimen with all femora and tibiae yellow that we attribute to T. boonrotpongi sp. nov. The tarsi are yellowish and not whitish (cf. Fig. 1). Other characters, such as the fore femur with long white soft bristles at the base, the general bristling of the legs and the male genitalia, also suggest that it represents T. boonrotpongi sp. nov. A future molecular analysis should ascertain if there is a genetic difference.</p></div>	https://treatment.plazi.org/id/236BEC56FFA7FFF1FDECFC72FEDBA9DF	Public Domain	No known copyright restrictions apply.

The latter species, however, has a dorsal bristle on the basal quarter of the fore tibia, lacking in T. minutus sp. nov. Further, it has the fore coxa darkened on the basal two-thirds and the apical tarsomere darkened as well. The fore coxa and even the apical tarsomere of all legs are yellow in T. minutus sp. nov. Finally, in T. peninsularis the first tarsomere of the fore leg is as long as the following tarsomeres together, while in T. minutus sp. nov. the first tarsomere is half as long as the following four tarsomeres together. Both species share a brownish tinged wing. In T. minutus sp. nov. the Tp and M are brownish seamed.</p><p>Thinophilus minutus sp. nov. should also be compared with T. dongae Grootaert et al., 2015, known from southern China. The latter species also has yellow fore coxae, no ventral bristles on the fore femur, no ventral spinules or bristles on the fore tibia. It has, however, the apical tarsomere of all legs black and mid and hind femora without ventral bristles. In T. minutus sp. nov. all tarsomeres are yellow and the mid and hind femora have short but distinct bristles. Both species are likely related in a species-group characterized by the similar shape of the cerci and surstyli.</p></div>	https://treatment.plazi.org/id/236BEC56FFAFFFF9FDCFFBC3FC8FAEA2	Public Domain	No known copyright restrictions apply.

Coxae and femora can vary in colour from yellow to brown and even dark brown.
