DELONG (1979) described Arapona with two new species:A. vallea DeLong, 1979 (from Panama), which was designated as the type-species, and A. devisa DeLong, 1979 (from Peru). Both were described from a single male. The genus was characterized by DELONG (1979) as follows: 1) head broadly rounded anteriorly; 2) disk of crown semicircular; 3) anterior margin of crown thin; 4) ocelli nearer anterior than posterior margin; 5) pronotum declivous; and 6) aedeagus with paraphyses (atrial processes). According to DELONG (1979), the species of Arapona and Gypona Germar, 1821 are similar and are closely related to Clinonella Delong & Freytag, 1971, based on the large slope of the pronotum.After studying a male specimen collected in Peru, we propose a new species, Arapona furcata sp. nov. The male was collected by light trap at the department of Madre de Dios. A key to the three known species of the genus is added. MATERIAL AND METHODSThe studied specimen is deposited at the Museo de Historia Natural, Universidad Nacional Mayor de San Marcos, Lima (MUSM). The terminology follows mainly YOUNG (1968, 1977), except for the head structures (HAMILTON 1981, MEJDALANI 1998 and leg chaetotaxy, (RAKITOV 1997). The techniques for preparation of male genital structures follow OMAN (1949) with some modifications described by CAVICHIOLI & TAKIYA (2012). Label data are given inside quotation marks with a reversed slash (\) separating lines on the labels and a semicolon separating different labels.Arapona furcata sp. nov. Figs 1-13Male holotype: total length 8.00 mm. Head and thorax. Head (Fig. 1) slightly produced, with median length of crown almost one-half interocular width and three-tenths transocular width; anterior margin broadly rounded, slightly longer medially than near eyes. Disk of crown almost smooth, with slightly marked and irregular striae, located near eyes. Ocelli located in front of imaginary line between anterior angles of eyes, closer to eyes than median line and closer to anterior than to posterior margin of crown. Head (Fig. 3), in lateral view, with margin of crown angulate and thin, with three carinae. Head (Fig. 2), in frontal view, with frons and clypeus slightly pubescent, with short and fine setae; frons slightly depressed medially; muscle impressions distinct; epistosmal suture incomplete. Clypeus continuous with profile of frons. Frontogenal suture reaching antennal ledges. Thorax with width between humeri slightly longer than transocular width, lateral pronotal margins slightly convergent anteriorly. Pronotum (Fig. 3), in lateral view, declivous, with disk finely striate except on anterior third. Mesonotum (Fig. 1) slightly rugose. Forewing 3.5 times longer than wide; venation distinct and elevate; three closed anteapical cells; central cell with transverse vein; five apical cells; apex rounded; appendix reduced. Hind l...
