Rossi( VAC).   Diagnosis: Males of  L. ecuadoriensiscan be easily recognized by the specific shape of sternite VII with its nearly semi-circular emargination in combination with the nearly straight posterior margin of tergite VII. Females are similar to the black coloured and densely punctate species  L. nigritaand  L. katharinae. They differ from  L. nigritaby the shorter elytra. Separation from  L. katharinaeis nearly impossible in females. The head is slightly less densely punctate than in  L. katharinae.   Description: Length: 5.0 mm. Colouration: Dark brown; pronotum, legs and antennae slightly lighter brown. Head: 0.75 mmlong, 0.61 mmwide; eyes large; slightly prominent; postocular sides twice as long as eyes; interantennal furrows deep; reaching anterior third of eyes; setiferous punctation deep and dense; anteriorly slightly denser than close to neck; on vertex, average of interstices between punctures as wide as diameter of punctures; small midline impunctate; space between interantennal lines impunctate except close to lines; surface without microsculpture; glossy. Antennae with first antennomere half as long as head; second and third antennomere longer than wide, conical; subsequent antennomeres wider than long and increasing in width; fourth antennomere nearly twice as wide as long; tenth antennomere nearly 2.5 times as wide as long; all antennomeres pubescent. Pronotum: 0.85 mmlong, 0.58 mmwide; widest in anterior third; anteriad, conically narrowed toward neck; in middle third distinctly narrowed, in posterior third slightly narrowed posteriad; posterior angles rounded; setiferous punctation as deep as on head but sparser; on average, interstices between punctures at least as wide as diameter of punctures; wide midline impunctate; irregular line adjacent to midline with 17 to 18 punctures; close to posterior margin impunctate; surface without microsculpture; glossy. Elytra: 0.80 mmlong, 0.78 mmwide; humeral angles obtuse but distinct; sides nearly parallel; posterior angles shortly rounded; posterior margin slightly convex with incision at suture; setiferous punctation deep and dense; on average, interstices between punctures half as wide as diameter of punctures; surface with weak isodiametric microsculpture; less shiny than head and pronotum. Abdomen with setiferous punctation as dense as on elytra but much finer; microsculpture transversely striate; deeper than on elytra; surface less shiny than elytra; sternite VII of male with deep semicircular emargination; tergite VII of male with sinuate posterior margin; nearly semi-circular central projection with adjacent emargination. Meso- and metatibiae with two subapical ctenidia each. Aedeagus long-oval with approximately rectangular anterior part; endophallus with two strings with posterior torsion; one string with large lobes in anterior part; second string densely covered by minute teeth; paramere slender and bilobed; inner lobe, straight in basal half; curved in apical half; with numerous setae at inner face; apical setae shorter and finer than basal setae; outer lobe much shorter than inner lobe; sinuate.   Etymology: The species is named after the country where the holotypewas collected. 1994-05-24 KNHM Hibbs Ecuador 270 -0.5 Sacha Lodge 7856 -76.5 12 41 1 Sucumbios 1994-05-24 KNHM Hibbs Ecuador 270 -0.5 Sacha Lodge 7856 -76.5 12 41 4 4 Sucumbios paratype 1994-05-24 KNHM Hibbs Ecuador 270 13 42 -0.5 Sacha Lodge 7856 -76.5 12 41 1 Sucumbios paratype 1994-06-03 KNHM, UIC Hibbs Ecuador 270 -0.5 Sacha Lodge 7856 -76.5 13 42 4 3 1 Sucumbios paratype [261,655,297,321] 1994-04-23 KNHM Ecuador 13 42 2 2 Sucumbios paratype Ecuador 270 -0.9 Sacha Lodge 7855 -76.5 13 42 1 Sucumbios paratype 1994-03-04 1994-06-03 1994-03-04 KNHM, UIC Hibbs Ecuador 13 42 5 4 1 Sucumbios paratype B99047 1999-03-24 KNHM R.
