Taxonomy of the Brazilian species previously placed in Mantispa Illiger, 1798 (Neuroptera: Mantispidae), with the description of three new species Author MACHADO, RENATO JOSÉ PIRES Author RAFAEL, JOSÉ ALBERTINO text Zootaxa 2010 2010-05-13 2454 1 1 61 http://dx.doi.org/10.11646/zootaxa.2454.1.1 journal article 10.11646/zootaxa.2454.1.1 1175­5334 10093813 Dicromantispa hyalina Machado & Rafael , new species (Figs. 9–10) Diagnosis. Ventromedial lobe completely sclerotized and curved; wings hyaline; ectoprocts dark brown. Holotype male. Vertex predominantly brown; except median region yellow dark brown spoted (Fig. 9c). Head in frontal view almost completely yellow, except for central longitudinal dark brown stripe beginning just behind antennae and ending at labrum (Fig. 9a). Mandible reddish-brown, except for base yellow. Palpi reddish-brown. Antenna with scape yellow, pedicel light brown, and flagellum dark brown (Fig. 9a). Pronotum: nearly straight in lateral view, with few setae in proximal and distal regions arising directly from it surface. Length-width-ratio at maculae: 6.1. Yellow, except for two brown lateral spots in anterior end and two brown small central stripes, one anterior and other posterior (Fig. 9c). Central stripes short, anterior stripe does not exceed maculae, and posterior one does not reach pronotum midlength. Between maculae and pronotum midlength there is a transverse brown stripe (Fig. 9c). Mesonotum: with three longitudinal dark brown stripes, one central and two lateral, with yellow stripes between them (Fig. 9c). Metanotum and both scutella completely dark brown (Fig. 9c). Scutella with 2 pores each one. Pteropleura predominantly yellow with anterior border dark brown (Fig. 9b). Foreleg: coxa reddish brown, except yellow base. Trochanter and tarsomeres reddish brown (Fig. 9d). Femur dark reddish brown, except area near spine row slightly light on the posterior surface (Fig. 9d). Basal spine light reddish brown, except base dark reddish brown. Tibia reddish brown, except for slightly dark dorsal area. Mid and hindlegs yellow, except coxae dark brown (Fig. 9b). Tarsal claws with four teeth. Forewing: length: 7.9 mm , 7 costal crossveins and 9 or 10 veins extended posteriorly from RP. Hyaline, except light yellow cell 1AP apex. Pterostigma light yellow with apex brown. Veins brown, except C, Sc, RA, AP2 and AP1 basal half (Fig. 9e). Hindwing: 5 costal crossveins and 9 veins extend posteriorly from RP; membrane color pattern similar to forewing. Veins brown, except for RA end of 1RA, C, Sc, AA and base of MP and CuA yellow (Fig. 9e). Abdomen with the first three tergites and sternites dark brown, others yellow with dark brown central longitudinal stripe enlarging posteriorly. Ectoproct completely dark brown. Tergites IV–VI with 2 groups of 1–2 pores in two transverse parallel rows anterolaterally; each group with one or two large pores or a scar between them ( Fig. 10a ). Terminalia: ectoproct posterior border rounded. Ventromedial lobe completely sclerotized, curved, with wide internal bend ( Fig. 10c, e ) with 6–7 stout setae and narrow external bend with 4–5 stout setae ( Fig. 10c, e ). Sternite IX, in ventral view, subpentagonal, with large medial rounded lobe at posterior border ( Fig. 10b ). Gonarcus without median lobe but with two large lateral lobes, easily seen in posterior and lateral view ( Fig. 10d, g ). Gonocoxite with constant width in ventral view ( Fig. 10f ), and apex slightly wide in lateral view ( Fig. 10g ). Basal two-thirds of mediuncus wider in lateral view and apex bifurcate in ventral view ( Fig. 10f, g ). Gonarcal membrane with subtriangular medial group of spinules ( Fig. 10f ). Pseudopenal membrane shorter than pseudopenis and with small scales on dorsal surface ( Fig. 10f ). Hypomere apex rounded with small granules ( Fig. 10f, g ). Paratypes . None. Geographical data. Species known only from the male holotype from Tocantins State , Brazil , collected in March . Discussion. D. hyalina seems to be close to D. gracilis because of the hyaline membrane of the wings and the absence of the gonarcus median lobe, but is clearly separated by the color pattern, ectoprocts completely dark brown and ventromedial lobe curved. Etymology. The specific name is derived from the Greek hyalos (= clear) and refers to the hyaline wing membrane.
