Type material: Holotype , f#, Brazil , Jundiaí –SP, Biological Reserve of Serra do Japi , 28.III.2019 , Kobal , R . et al ., col. (LESTES collection– UFTM , voucher nº Hym–006/0001). Diagnosis: FEMALE. This species can be distinguished from all other species of Entypus by the following combination of morphological characteristics: body black without metallic reflections; antenna dark brown with F1 (distal third), F2, F3 and F4 orange; wings amber with tip slightly lighter; clypeus apical margin very slightly emarginate; mesosternum with small and angulated process; propodeum and metapleuron striated; hind tibia with dorsal face serrate and inner brush interrupted prior to the distal apex; 3rd submarginal cell larger than 2nd one; S2 with tubercles very little developed and looking integumentary bumps. This new species is somewhat similar to Entypus nitidus (Banks) , but it can be differentiated by the clypeus, antennae coloration, wing venation and coloration. E. nitidus has the apical margin of the clypeus stronger emarginated, antennal flagellum completely orange, 3rd submarginal cell with similar size to 2nd one, and wing tip infuscate (photos of the holotype of E. nitidus are available in the MCZ specimen database and can be accessed searching for Priocnemioides nitidus Banks in: https://mczbase.mcz.harvard.edu/SpecimenSearch.cfm). Description. FEMALE, holotype . Body length 14.0 mm. Color. Body black; distal third of F1 orange, F2–F4 fully orange; wings amber with tip slightly lighter ( Fig. 3 ). Body covered by dark pubescence; head and mesosoma densely cover with long dark setae. Head. HW: HH = 1.19; MID: HW = 0.57. Eyes convergent above, with UID: LID = 0.84. Ocellar triangle small; POD: OOD = 0.43. Gena well developed. Malar space very short, latero-inferior margin of the head margin close to the eye margin, but not touching it. Clypeus large, regularly convex; width 2.39x its height; apical margin carinate, very slightly emarginate centrally ( Fig. 4 ). Mandible stout, with two teeth, one on the inner margin and the other on the apical margin. Labrum not exposed, apical margin slightly emarginated and with long setae. Maxillary palpi IV–VI with subequal length. Antenna elongated, with cylindrical flagellomeres and ratio of the five first antennomers length (scape: pedicel: F1: F2: F3) 2: 0.6: 3.5: 2.8: 2.6; F1 length 5.5x its most distal width; F10 length 6.2x its most proximal width, pointed apically. Mesosoma . Mesosoma length: 4.88 mm ; forewing: 6.89 mm . Pronotum short, without a distinct dorsal surface and with posterior margin angled. Mesoscutum convex, notaulus distinctly impressed. Mesoscutellum and metanotum strongly convex. Mesopleuron strongly convex. Mesosternal process small and angulated ( Fig. 5 ). Metaposnotum longitudinally striated, distinctly shorter than metanotum (0.24x the metanotum length), emarginated postero-medially. Propodeum strongly convex and striated ( Figs 3, 6 ). Metapleuron striated ( Fig. 6 ). Third submarginal cell larger (i.e., longer and wider) than second; R at the sector between 2r-m and 3r-m longer than it at between 1r-m and 2r-m ( Fig. 3 ). Procoxa with distal inner margin strongly emarginated ( Fig. 7 ); hind tibia with two lines of tegumental projection on the proximal fourth and one line on the rest of the tibia length; inner hind tibial brush interrupted prior to the distal apex; last tarsomere of all legs with two lines of spiniform setae and with dentated claws. Metasoma. T1 with distinct lateral groove; T6 covered with several stout setae. S2 with tubercles slightly elevated, such as swellings ( Fig. 8 ); S3 – S5 with long backward setae irregularly distributed on the posterior half; S6 with similar setae of anterior sternum (i.e., S5) on the posterior two thirds. Distribution. Known only from the type locality in Biological Reserve of Serra do Japi, Jundiaí–SP. Etymology. Named in honor of Renata Aparecida de Andrade Cavallari, employee of the Graduate Program in Entomology, Faculty of Philosophy, Sciences and Letters at Ribeirão Preto—University of São Paulo in honor to her great contributions to Brazilian Entomology, a beloved friend that took part on the formation of hundreds of entomologists. Host. Ctenus ornatus Keyserling ( Araneae : Ctenidae ).
