Biguembia troncol n. sp.

( FigureS 27–31 )

Type material. Male holotype from Brazil: AmazonaS, Itacoatiara , 02° 45’ 10’’ S 58° 39’ 11’’ W, 29-30-XI-2005, at light, J.A. Rafael, R.J.P. Machado, A. SilVa. DepoSited in INPA.

Etymology. ThiS SpecieS iS dedicated to Victoria (Claudia’S daughter) and her childhood; troncol meanS control (and here implieS a teleViSion remote control).

Diagnosis. Biguembia troncol n. sp. differS from B. obscura in haVing a Submentum with a broad baSe; the Shape and poSition of LC1dp, which iS quadrangular and apical; the 10Rp2 long and Straight ( Fig. 30 ); the outer tip of 10Lp1 Small (leSS than the half of the inner tip); and the preSence of a deep depreSSion between 10Lp1 and 10L.

Male holotype. Head, antenna and terminalia yellowiSh brown, the reSt of the body yellowiSh white.

Total length 7.01 mm. Head almoSt quadrangular ( Fig. 27 ), width/length = 0.90; OR = 0.44; Md with 3–2 inciSor teeth and 1–1 molar teeth; Mm conSpicuouS, Sm quadrangular with anterior margin membranouS ( Fig. 28 ). Forewing length 5.89 mm, hind wing 4.85 mm. Wing VeinS Sc, R1, RS, Cu and A conSpicuouS; Ma1, Ma2 and Mp clearly not reaching wing edge; Cua diffuSe. CroSS-VeinS forewing, R1-RS: 4, RS-Ma: 1, RS-Ma1: 1, Ma-Mp: 1, Ma1-Ma2: 1. Hind legS loSt.

On terminalia ( FigS. 29–31 ) 10R with membranouS area almoSt abSent ( Fig. 30 ). 10Rp1 well deVeloped with longitudinal keelS ( FigS. 29 and 30 ), both tipS Sclerotized; microtrichia preSent between 10R and 10Rp2. Outer tip of 10Lp conical and membranouS, little Shorter than the inner tip ( Fig. 31 ). Hp apically unpigmented; inner node of Lpp conSpicuouS ( Fig. 31 ). Longitudinal ratio of LC1/LC2 = 0.75, LC1dp quadrangular, LC1dp/LC1width = 2 (length of LCdp twice the width of LC1).

Female. Unknown.

Additional records. There are two localitieS from Amazonia of Brazil ( Fig. 18 ) liSted by RoSS (2001) aS SpecimenS of B. obscura but iS probable that thoSe SpecimenS belong to B. troncol . Future Study of thiS material iS needed to confirm thiS Statement.
