Figs 1–4 .

MATERIAL. 1♂ — Peru, Junin Reg., Satipo Prov., near Rio Venado vill., h = 1122 m, 11°11.787´S 74°46.168´W, 20– 30.10.2022, leg. A. Sokolov ( MSPU).

NOTES. This species was described from a single female from Manu Biosphere Reserve, Pakitza Park Ranger Post in the Peruvian Department of Madre de Dios [ Sumlin, 1993]. Until now in Peru L. mellicollis was known only from mentioned above locality [ Sumlin, 1993; Pearson, Huber, 1994; Erwin, Pearson, 2008]. The main measurements of the holotype (female) are — TL = 7.7 mm, EW = 2.6 mm [ Sumlin, 1993], and in collected early female TL = 9.0 mm [ Erwin, 1990; Erwin, Pearson, 2008: Pl. 22]. In addition, this species was found in the Colombian Department of Amazonas (according to the map — in Tarapacá Municipality) without sex and number mentions, but with the range of TL = 7.0– 8.5 mm [ Vítolo, Pearson, 2003; Vítolo, 2004]. The information on morphology of the male is still absent [ Sumlin, 1993; Pearson, Huber, 1994; Erwin, Pearson, 2008]. Thus, in the Peruvian Region of Junin L. mellicollis is recorded for the first time. Moreover, the male of this species is also illustrated for the first time ( Figs 1–4 ). Its main measurements are (in mm) — TL = 7.9, HW = 2.4, OW = 1.5, LL = 0.8, LW = 1.0, PL = 1.4, PW = 1.5, EL = 5.0, EW = 2.6, AL = 2.5. Labrum pale with light brown lateral and basal margins, six teeth and relatively broad and flat apical portion, as well as six long marginal setae ( Fig. 2 ). Three basal tarsomeres of fore legs are very wide and densely haired by long black setae ( Figs 1, 3 ). Aedeagus with very large, curved ventrally hook ( Fig. 4 ).
