Lyrifissures ih located posteroventrally. Measurements of setae: pt 9 (8–15); mtα 10 (9–15) and; mtβ 10 (8–13). Four pairs of aggenital setae (ag1, ag2, ag3 and ag4) and one pair of pseudanal setae (ps2).

Male. not found.

Etymology. The name meliponarum derives from the name of the stingless bee tribe Meliponini .

Remarks. This new species resembles L. obnoxia (Kuznetzov & Zapletina, in Livshitz et al. 1972) , which has short dorsal setae, no empodial hooks and Tydeus striations. Nevertheless, it differs as its dorsal setae are serrated instead of lanceolate, its trichobothria (bo) are serrated instead of smooth and setae d are bifurcated. This new species is also similar to L. oregonensis ( Baker, 1970) as its dorsal setae are serrated and it has Tydeus striations. Nonetheless, it differs because its dorsal setae are short (f1 and f2 do not reach the bases of h1 and h2, respectively) instead of long (f1 and f2 reach the bases of h1 and h2, respectively). In addition, its leg setae are serrated (except tc ’, tc ” and ft ’ on leg I) instead of smooth, its empodium has claws instead of without claws, it has transverse striae between the ventral setae mtα and mtβ instead of in a V-pattern, and solenidion ωI is distinctly less than ½ the width of tarsus I instead of being longer than ½ the width of tarsus I.
