Head pattern ( Fig. 126 ), vertex light brown; front with brown spots; an ochre diagonal band between the inner borders of each compound eye to the epistomal sulcus; two brown vertical bands on the pale brown genae; postgenae light brown. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Labrum, anteclypeus, postclypeus and mandibles pale brown, postclypeus with dark brown spot anteriorly. Antennae: scape and pedicel brown; flagella pale brown. Maxillary palps pale brown, Mx4 dark brown. Tergal lobes of meso- and metathorax dark brown, with light brown edges.

Vertex at the same level of the upper border of the compound eyes; outer cusp of lacinial tips broad, with 5–6 denticles. Mx4/ Mx2: 1.15. Forewings ( Fig. 124 ) L/W: 2.73; pterostigma: lp/wp: 5.18, elongate, wider in the middle; M six or seven-branched, M6 or M7 forked; areola postica: la/ha: 1.20, tall, broadly triangular, apically rounded. Hindwings ( Fig. 125 ) l/w: 3.03; M three-branched. Subgenital plate ( Fig. 127 ) wide, setose, with posterior border rounded. Gonapophyses ( Fig. 129 ): v1 elongate, slender and acuminate; v2+3 with a proximal slender heel, v2 with a row of 6–7 setae; distal process long, sinuous and acuminate, bearing microspicules on surface. Ninth sternum ( Fig. 129 ). Paraprocts ( Fig. 128 ) broadly triangular, with long and short setae posteriorly; sensory fields with 27–28 trichobothria on basal rosettes. Epiproct ( Fig. 128 ) triangular, proximally wide, with long and short setae as illustrated.

Material studied. Holotype female. COLOMBIA. Putumayo. Puerto Asís. Las Delicias, 0°22’09.50” N: 76°31’01.98” W. 264 m. 28.III.2014. Beating vegetation. J. Panche. MUSENUV slide code 29328 . Paratypes: 1 female, same data as the holotype. 30.II.2015 . 1 female, Caquetá, San Vicente del Caguán, Laureles, Reserva Indígena Altamira , 2º27’50.14”N: 74º55’2.06”W, 917 m . 26.III.2017, beating vegetation. J. Panche.

Etymology. This species is dedicated to the Murui indigenous people, that inhabit the Caquetá Department, Colombia.

Remarks. L. boliviana Williner , L. colombiana García Aldrete et al. , L. deibyi Mendivil et al. , L. maracaensis García Aldrete and L. raramuri García Aldrete share with L. murui having the wings hyaline, without brown spots on vein ends at wing margin, but the latter differs from them in having the forewing pterostigma elongate, shallow and completely unpigmented, in the shape of the pigmented area of the subgenital plate, and in the shape of the ninth sternum. It probably belongs in a group of its own, which awaits confirmation when the male be known (García Aldrete, 2003, 2004; García Aldrete et al., 2011 a; Mendivil et al., 2017, Williner, 1949).
