Ecuador : Orellana : Tiputini Biodiversity Station , near Yasuni National Forest , 00 o 37’S 76 o 08’W , 9-II-1999 , 220- 250 m , fogging terre firme forest, T.L. Erwin ( WOPC , 1) ; Reserva Ethnica , Waorani , 1 km S of Onkone Gare Camp , 00 o 39’S 76 o 27’W , 1-VII- 1995 , 216 m, T.L. Erwin ( USNM , 1) ; idem , 2-II- 1996 , 220 m, T.L. Erwin ( WOPC , 1) Diagnosis ( Fig. 58 ): Specimens of this species resemble superficially those of P . iota Opitz , from which they are distinguished by the coloration of the pronotum and legs. In P. lena , the pronotum is uniformly dark brown and the legs are completely stramineous, whereas in P . iota the pronotum is castaneous at the sides and the legs are bicolorous. Description. Size : Length 3.8 mm ; width 1.2 mm . Integument : Cranium black; thorax dark brown; legs yellow; elytral color variegated, predominantly dark-castaneous, flavotestaceous triagonal posthumeral macula well developed. Head : Antenna as in Fig. 15 . Thorax : Pronotal anterior margin notably projected at middle; elytral epipleural margin with conspicuous trichobothria; protibial anterior margin with 1 spine. Abdomen : Pygidium narrow scutiform in females, extraordinarily robust in males; aedeagus as in figure 34. Variation. Size : Length 3.8-4.0 mm; width 1.5- 1.4 mm . Other than size, the available specimens are quite homogeneous. Natural History. The available specimens were collected in January, February, and July from a tropical forest, by fogging, at from 216 to 250 m . Distribution. Known only from the forested environs of Reserva Waorani, In eastern Ecuador . Etymology. The trivial name lenis (= soft) is a Latin adjective. I refer to the velvety appearance of these beetles. Taxonomic Notes. The key to species of Plocamocera Spinola ( Opitz 2004: 28 ) should be modified as follows to accommodate this species: 4(3'). Antennomere 10 robust, only slightly longer than antennomere 9 ............................................ 5 – Antennomere 10 slender, considerably longer than antennomere 9 ........................................... 6 5(4). Pronotum castaneous at sides; legs bicolorous ( Brazil : Mato Grosso ) ............................................ ......................................................................................................... Plocamocera iota Opitz – Pronotum uniformly dark brown; legs stramineus ( Ecuador : Orellana ) ....................................... .............................................................................................
