Diagnosis

As in generic diagnosis (see Mockford 2004), plus the following: clunium bearing on the posterior margin a pair or heavily sclerotized lateral spines. Paraprocts with proximal handle. Hypandrium with pp, mbp and ldp anteriorly directed (posteriorly directed in T. thorntoni ); bp absent.

Etymology

The specific name refers to the nature of the area (Amazonian forest), where the types were collected.

Type material

Holotype

BRAZIL: ♂, Amazonas, AM 0 10, Reserva Florestal Adolpho Ducke, Mixed light, 2 May 2002, J. Vidal.

Paratype

BRAZIL: 1 ♂, same data as the holotype ( INPA).

Description (male)

COLOR (in 70% ethanol). Body light brown. Compound eyes black, ocelli hyaline. A broad dark brown band over most of the frontal suture, ending at the antennal fossae. Flagellum with f1 black, other flagellomeres brown. Pronotum and mesonotum with median black stripe. Legs brown. Fore- and hindwings with variable pigmentation and dark brown veins except for Cu1a and IA (white); pterostigma brown; a dark brown spot from discoidal cell to distal area. Hindwing without markings except basally.

MORPHOLOGY. Compound eyes relatively small, the anterior borders not reaching the level of the convex vertex; antennae with first flagellomeres thickened and densely covered with setae. Forewing with elongate pterostigma; clunium bearing a pair of well-developed and heavily sclerotized lateral spines and with clunial shelf covering base of epiproct. Epiproct simple, rounded and semi-membranous. Posterior projection of paraprocts long and acuminate, inwardly directed; large sensory fields with many (> 100) trichobothria in basal rosettes. Hypandrium symmetrical, bearing short and acute median pp; mdp a massive bulb lacking bp; pp distally quadrangular and outwardly directed, bearing spines, spicules and setae over the surface; a heavily sclerotized and continuous band between pp and mdp. Phallosome closed, elongate, with a denticulate apical process, ending in a short tooth; endophallus laterally spinulose.

MEASUREMENTS (in μm). FW: 6600, HW: 4600, Mx 4: 330, f1: 740, f2: 2320, f3: 109, IO: 970, D: 210, d: 350, IO/d: 4.61, PO: 1.6.
