description: <i>Dinelytron betinho</i> <b>sp. nov.</b> Fig. 8A-B. <i>Examined material</i>. Holotype <i>_</i> (Fig. 8A-B, D): “Viçosa, MG [Minas Gerais], BRASIL, Data 10.xi.1982, Fiuza &amp; Martins [collector], Corrego do Paraíso, Mata da Prefeitura, Armadilha UV [blacklight trap]” (UFV). Paratypes: same data as holotype, except “ 4.xi.1981 ” (1 <i>_</i> UFV); “ 10.xi.1982 ” (3 <i>_</i> UFV). <i>Etymology</i>. The species name is dedicated to Alberto Moreira Silva Neto, nicknamed “betinho”. <i>Diagnosis</i>. Clypeus 4.7 times wider than high (Fig. 8C-D). Median vein of tegmina bifurcated in Medial anterior and Medial posterior at base; Medial anterior bifurcated in medial anterior 1 and 2 at approximately half the length of tegmina (Fig. 8E). Male subgenital plate with lateral projection at apical margin (Fig. 9B). Male genitalia in dorsal view: basal pouch auriform (Figs. 4, 5 and 10). Apex of dorsal left sclerite <i>þ</i> left posterior process ovoid (Figs. 4, 5 and 10). Internal sclerite two times shorter than basal pouch, somewhat reniform (Fig. 10). <i>Description</i>. Body dark brown. Head. Frontal suture conspicuous, forming conspicuous light brown sulcus (Fig. 8C); coronal suture conspicuous. Clypeus 4.7 times wider than high, light yellow with light brown spots; medially with inconspicuous depression (Fig. 8C, D). Labrum light yellow, asymmetric, with left half slightly longer than right half (Fig. 8C, D). Antenna with flagellomere 1 subrectangular, 2.5 times longer than wide and three times longer than flagellomere 2; flagellomere 2 subquadrangular; flagellomere 3 rectangular, two times longer than flagellomere 2. Compound eye globose, light brown with black spots (Fig. 8C). Thorax. Pronotum with median longitudinal sulcus and transversal black spot at apical margin. Mesonotum 2.2 times longer than pronotum, with black spot at basal margin, median longitudinal carina. Coxopleurite rugose, light brown, semi-ellipsoid (Fig. 8B). Mesothoracic epimeron smooth, light brown, rounded; mesothoracic episternum rugose, anteriorly light brown, posteriorly dark brown, subtriangular (Fig. 8B). Metathoracic pleural region smooth, subtrapezoidal (Fig. 8B). Thoracic venter yellow, with dark brown longitudinal medial line from base to apex. Probasisternum trapezoidal, with anterior margin arched, convex. Meso- and meta-basisterna smooth, rectangular, longer than wide, with medial circular sclerite concolor with venter. Legs. All legs dorsally light brown (Fig. 8B), ventrally light yellow, laterally with white setae; apical third of femurs and basal third of tibias with black spots (Fig.8A, B). Anterior femur 6 times longer than wide, dorsally with three conspicuous longitudinal parallel carinae (Fig. 8B); ventrally smooth. Anterior tibia dorsally setose, with two conspicuous longitudinal carinae; ventrally smooth. Mid femur ventrally with median longitudinal carina and four spines at anterior margin. Posterior femur with three longitudinal parallel carinae dorsally; ventrally with six inconspicuous spines at anterior margin; ventro-posterior margin slightly sinuous, better observed ventrally. Wings. Tegmina light brown, with rounded apex (Fig. 8E). Radial vein subdivided in Radial anterior and Radial posterior at apical third (Fig. 8E). Median vein bifurcated in Medial anterior and Medial posterior at base; Medial anterior bifurcated in medial anterior 1 and 2 at approximately half the length of tegmina (Fig. 8E). Cubital vein slightly curved. Posterior wing with distal portion of costal area concolor with tegmina; veins of anal area inconspicuous. Abdomen. Abdominal terga opaque. Terga 1-7 rectangular, longer than wide, with longitudinal medial carinae and sparse granules. Tergum 8 trapezoidal, 1.2 times longer than tergum 9 (Fig. 9A). Tergum 9 trapezoidal, with basal margin straight,1.3 times wider than apical margin, which is slightly concave (Fig.9A).Tergum 10 two times shorter than Tergum 8, with basal margin concave, lateral margin straight, apical margin convex (Fig. 9A). Cercus laterally flattened, with setae (Fig. 9A, C). Sterna 1-9 gradually decreasing in length. Sterna 7-9 with conspicuous wide longitudinal medial sulcus (Fig. 9B). Sternum 7 rectangular, 1.6 times wider than long with all margins straight (Fig. 9B). Sternum 8 rectangular, three times wider than long, with convex basal and lateral margins, sinuous apical margin (Fig. 9B). Subgenital plate (sternum 9), rectangular, with basal and lateral margin convex; apical margin concave, laterally with rhomboid projection (Fig. 9B). Vomer with slightly sinuous lateral margin, acute and black apex (Fig. 6C). Genitalia (Figs. 4, 5 and 10). Basal pouch auriform. Dorsal left sclerite attached to dorsal wall of genitalia; medial portion of dorsal left sclerite conspicuously arched; apex of dorsal left sclerite <i>þ</i> left posterior process ovoid. Left posterior process conspicuous. Internal sclerite two times shorter than basal pouch, somewhat reniform, in dorsal view seeming to be located underneath the basal pouch. Flagellum present. <i>Measurements</i> (mm). Body length 34.5-35.2; dorsal head length 1.5-1.7; pronotum 1.4-1.5; mesonotum 1.2-1.3; anterior femur 6.5-6.6; anterior tibia 3.2-3.3; mid femur 3.6; mid tibia 2.4-2.7; posterior femur 6.7; posterior tibia 4.3-4.4. <i>Type condition</i>. Holotype: left anterior and right posterior legs and left antenna glued to a piece of label paper pinned to the specimen support. Right antenna with approximately half the length missing. <i>Geographical records</i>. Brazil, <i>Minas Gerais</i>: Viçosa. <i>Remarks</i>. This species can be easily distinguished from all other <i>Dinelytron</i> species by the subgenital plate with latero-apical rhomboid projection on the apical margin.
