(Figs 55–66)
Diagnosis. Like L. bonaverensis n. sp. and L. chelata, it presents phallosome sledgehammer-shaped. Unlike these, it has external parameres with short apical lobes, endophallus with large sclerotized area and membrane with abundant spicules (Fig. 60). Subgenital plate subrectangular, with apical lobe of uniform broad and ‘U’–shaped (Fig. 59).
Male. Color. Head (Fig. 57) dark Brown, with darker spots on the vertex and postclypeus. Compound eyes black, ocelli hyaline, with ochre centripetal crescents. Coxae dark brown, femur brown, with a fringe white-creamy in the middle portion, tibia white-creamy with brown apex, tarsus 1 white-creamy, tarsi 2 and 3 brown. Forewing (Fig. 55) peppered light brown, veins brown, alar margin, subcostal and anal vein punctate, anal cell with dark brown spots, pterostigma with dark brown small dots which extend outside the margin, but retaining its shape, vein m with dark brown spot distally. Hindwings (Fig. 56) smoky, veins brown and dotted costal margin. Clunium and hypandrium (Fig. 59) dark brown, epiproct and paraprocts little pigmented (Fig. 58).
Morphology. As in diagnosis, plus the following: Head (Fig. 57): H/MxW: 1.26; compound eyes large, H/D: 1.39; IO/MxW: 0.44. Vertex slightly concave, below level of upper margin of compound eyes. Outer cusp of lacinial tips broad, with five denticles; Mx4/Mx2: 1.31. Forewings (Fig. 55): L/W: 2.74. Vertex straight. Pterostigma: lp/wp: 3.23, areola postica high, with vertex touching vein M: al/ah: 1.45. Hindwings (Fig. 56): l/w: 2.76. Hypandrium subtriangular,V-shaped, rounded apically with setae as illustrated (Fig. 59),with preapical setae and three macrosetae. Phallosome (Fig. 60). Paraprocts (Fig. 58) with two small tubercles, medial one membranous and covered with setae and the second covered with spicules and short setae, with a curved up lateral projection sclerotized, prong (process) short hook-shaped, strongly curved and external setae on tubercles; sensory fields with 31 trichobothria on basal rosettes. Epiproct (Fig. 58) crescent-shaped, with cross-medial sclerotization covered by a row of setae.
Measurements. FW: 3125, HW: 2350, F: 625, T: 1175, t1: 440, t2: 67, t3: 83, ctt1: 19, f1: 700, f2: 625, f3: 567.5, Mx4: 184, IO: 240, d: 360, D: 490, IO/d: 0.67, PO: 0.73
Female. Color. Essentially as in males. Head (Fig. 63) clearer than in males, with longitudinal middle spot dark brown, clypeus dark brown. Wings (Figs 61 and 62) clearer than in males.
Morphology. As in diagnosis, plus the following: Head (Fig. 63). H/MxW: 1.21; Vertex somewhat sinuous, slightly above upper level of compound eyes, these smaller than in males, H/D: 2.32, widely separated, IO/MxW: 0.71. Outer cusp of lacinial tips little wide, with five denticles; Mx4/Mx2: 1.25. Forewings (Fig. 61): L/W: 2.56. Pterostigma: lp/wp: 3.02, areola postica almost as tall as wide, apically angled: al/ah: 1.34. Hindwings (Fig. 62): l/w: 2.60. Paraprocts subrectangular (Fig. 64), with short external margin, distally and apical margin with rows of setae and macrosetae; lateroapical external area with group of abundant setae; sensory fields with 32 trichobothria on basal rosettes. Epiproct (Fig. 64) subtriangular, broadly rounded apically and basal margin almost straight, distal field with setae and four macrosetae, apical margin with few setae. Subgenital plate (Fig. 65). Gonapophyses typical to family (Fig. 66), V1 apically acuminate, with microsetae, V2 distally acuminate, more than twice the length of V1, V3 oval and with setae and macrosetae as illustrated.
