Metabasitarsus 0.5 × length of corresponding tarsus. Fore wing with cell 2Rs as long on Rs as on M; hindwing with anal cell present ( Fig. 7a). 1 stvalvulae broad, triangular, tapering gradually to apex; lamnium with 16 annuli decreasing in width distally ( Fig. 7f); each annulus bordered anteriorly by row of broad ctenidia, first 4 proximal annuli present, with ctenidia only on dorsal half, subsequent annuli with ctenidia dorsoventrally; ctenidia length increasing toward ventral region of valvula; ctenidia longest close to upper margin of sclerora ( Fig. 7f,h); wall of each annulus with spiniform microtrichia, arranged into irregular patches; first proximal four annuli with lateral and circular campaniform sensilla, irregularly distributed; sclerora provided with marginal campaniform sensilla, one on each annulus, except for first three proximal annuli which contain multiple sensilla ( Fig. 7f,h); ventral surface of each annulus with deltoid sawteeth projected anteriorly as rounded lobe, each lobe with semicircular notch ( Fig. 7g); area distal to notch of each sawtooth having multiple serrulae; distal region of first valvula with undifferentiated sawteeth although with numerous irregular serrulae. Third valvulae with short apicolateral lobes (= scopae s. Ross 1937), in ventral view slightly shorter than apex of valvulae. Abdomen with T1 almost completely reduced or membranized. Color.Head black with white spot on supraclypeal area; antenna black. Thorax black anteriorly, with posterior half surface of mesoscutum median lobe (two transverse black spots on anterior margin of axillae) and tegula orange; metascutellum and its lateral arms white with black spot on metascutellum medially; mesopleural wing process, dorsal half of pleural suture and mesotransepimeral suture white. Legs white with distal half of tibiae and tarsi black ( Fig. 7a–d). Prefemur with proximal transversal black spot. Wings black. Abdomen, valvifers and third valvulae black.  Male:Unknown.     Holotype: ♀. COLOMBIA.  Caquetá,  Florencia, Vda.

Malagónleg. Depositedat UNAB 3706.   Etymology:The species name refers to the Amazonas region of Colombiawhere the specimen was collected.   Remarks:Color pattern of the holotypeis similar to that of deltaand midea; however, the pronotum and antenna are black in  amazonicus. In addition, the singular notch in each sawtooth on first valvula allow to distinguish the species.   Host:Reared from young plants of  Zygia longifolia(Fabaceae). Larvae and cocoon found on leaves of the host ( Fig. 7e).    Ptenossp.:  COLOMBIA.  Cundinamarca,  Arbelaez,  1417m, 4°16’N, 74°24’W,  09 August 1996, A.
