Diagnosis. Dorsal and ventral shields with serrated setae, including trichobothria. Serrated setae on legs I-IV (except tc ’, tc ” and ft ’ of leg I). Setae d bifurcated. Dorsal ornamentation mostly striated, type Tydeus, with longitudinal striae between ro, la and bo. Empodial hooks absent.

Striation between f1, f2, h1 and h2 transverse (Fig. 2E). Eyes absent. All dorsal setae serrate, not reaching setae in next row (excluding bo). Bothridial setae (bo) filiform.

Venter (Fig. 3). All ventral setae serrated and completely striated. Longitudinal striae between pt setae, transverse striae between pt, mtα and mtβ. 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). Setal lengths: ag1 7 (5–8); ag2 8 (6–12); ag3 5 (5–8); ag4 9 (8–12); g1 4 (3–6); g2 4 (3–7); g3 4 (3–5); g4 3 (1–6); g5 4 (2–6); g6 4 (1–5) and; ps2 12 (8–15) (Fig. 4A). Shape of cg organ elliptical (Fig.3).
Gnathosoma (Fig. 5). Length 49 (49–59), width 42 (40–49). Gnathosoma visible from above. Subcapitulum with longitudinal striae behind sc1 and sc2. Infracapitular setae simple. Setal lengths: sc1 3 (3–6), sc 2 7 (6–12). Palp 48 (46–59) long, setation 5(+1ω)-2-2 (Fig. 6), setae d bifurcate. Palp tarsus with eupathidium ρζ semilunar distally (Fig. 4B). Palptarsus significantly longer than cheliceral digits. Cheliceral stilettos 17 (10–17) long.
Legs (Fig. 7 A-D). All leg setae serrated (except tc ’, tc ” and ft ’ of leg I). Tarsi I-IV with two claws and hairy empodium but empodial hooks (om) are absent. Chaetotaxy of legs I–IV (tarsus to trochanter): I: 8(+1ω)-3(+1κ)-3- 3-1 (Fig. 7A); II: 6(+1ω)-2-2-3-1 (Fig. 7B); III: 5-2-1-2-1 (Fig. 7C) and; IV: 5-2-1-1-0 Fig. 7D). Length of leg I 147 (147–203); leg II 114 (114–165); leg III 135 (115–195) and; leg IV 147 (122–196).

Type material. Female holotype, eight female paratypes, as follows: Holotype, six paratypes, Porto Alegre, Rio Grande do Sul, Brazil, from nests of T. fiebrigi, September 21, 2018, T. Da-Costa. Two paratype females, Bom Princípio, Rio Grande do Sul, Brazil, from nest of M. quadrifasciata, October 10, 2018, T. Da-Costa. Female holotype and a female paratype deposited at the Departamento de Entomologia e Acarologia, Escola Superior de Agricultura “ Luiz de Queiroz ”, Universidade de São Paulo (ESALQ / USP), Piracicaba, state of São Paulo, Brazil. Two paratypes were deposited at the Museu de Ciências e Tecnologia, Pontifical Catholic University of Rio Grande do Sul (PUCRS), Porto Alegre, Rio Grande do Sul, Brazil. Other paratypes were deposited at the Museu de Ciências Naturais (ZAUMCN), Universidade do Vale do Taquari—Univates, Lajeado, Rio Grande do Sul, Brazil.
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.
