Type material.

Holotype: male, Brazil: Pará, Oriximiná, Rio Trombetas-Alcoa. Min., 13-X-2000, J.A. Rafael leg., INPA.

Diagnosis.

Chromatoclothoda langa sp. nov. is close to C. elegantula Ross, 1987 described from specimens from Reserva Ducke, but the new species can be distinguished by several conditions: Sm uniformly depressed instead of two oval strongly depressed areas as in C. elegantula ; Hp uniformly pigmented and starting at the right side of H instead of depigmented and starting at the center of H; 10Rp1 conspicuous, triangular instead of almost blunt as in C. elegantula ; Ep broad and well sclerotized instead of Ep very slender as in C. elegantula ; LC2 longer than LC1 instead of shorter than LC1 as in C. elegantula .

Description.

Male (holotype). Head dark brown, thorax brownish yellow, antenna, legs, and abdomen brown, except for the apical antennomeres and LC2 which are white. Total length 12.22. Head width/length = 0.82, postocular suture well developed; OR = 0.62; Md with 3-2 incisor teeth and 3-2 molar teeth; Mm inconspicuous, Sm strongly depressed, base broad, wider than anterior margin, anterior margin concave (Fig. 43 ). Forewing length 9.12, hindwing length 8.58. Wing base union type A; wing venation: all longitudinal veins conspicuous; Ma1, Ma2, and Mp clearly not reaching wing edge, cross-veins in forewing: R1-Ma+Rs: 1; R1-Rs: 4-5; Rs-Ma: 0-1; Rs-Ma1: 1-2; Ma1-Ma2: 0-1; Ma+Rs-Mp: 0-1; Ma-Mp: 1; Mp-Cua: 1-2 (Fig. 44 ). Basitarsus of hind leg broad (Fig. 45 ): length 0.43, width/length = 0.30; medial bladder diameter/ basitarsus width = 0.31; two rows of setae on retrolateral face, two rows on anterolateral face, four or five rows on ventrobasal face (Fig. 45 ). Terminalia (Figs 46 , 47 ) inner apical angle of 10L with 10Lp inconspicuous, 10Rp1 triangular and acute (Fig. 46 ). Membranous area between 10R and 10L narrow, Ep conspicuous. Hp not centered, starts in the right side of H (Fig. 47 ). Lpp is a well sclerotized plate, almost the same size as Hp; Rpp reduced as narrow well sclerotized band (Fig. 47 ). LC2 slightly longer than LC1, longitudinal ratio of LC1/LC2 = 0.85. Female. Unknown.

Etymology.

This species is dedicated to Langa, a childhood friend of Lucia and Victoria ( Claudia’s daughters).
