Prisopoides villosipes ( Redtenbacher, 1906) View in CoL comb. nov.

Fig. 42A-B View Fig .

Examined material. Holotype (examined by photo): “HT [holotype] _ Museum Paris” “ Bresil [ Brasil], Minas Gerais, Caraca [¼ Serra do Caraça ], Gounelle [leg.], 8118-[18]89” “Redtenb., type, Redtenbacher det., 1900”. (1 _ MNHN).

Ordinary material: “ BRASIL, Itatiaia (1.100 Mtr.), Est. do Rio de Janeiro, Diringa”//“OUT [October], 1962” (1 _ MZUSP).

Diagnosis. Mid femur dorsally with apical projection; elongated and widened at posterior margin ( Fig. 42D View Fig ). Posterior femur in dorsal view with conspicuous pointed projections at posterior margin ( Fig. 42E View Fig ). Abdominal sterna laterally brown, medially black ( Fig. 42F View Fig ). Sternum 7 rectangular, 1.5 times wider than long ( Fig. 44A View Fig ). Subgenital plate with posterior margin almost straight, and medial projection conspicuously emarginated ( Fig. 44A View Fig ). Vomer with base enlarged, lateral margin straight, apex rounded, weakly sclerotized ( Fig. 44B View Fig ). Basal pouch elongated, 2.6 times longer than wide; in dorsal view with left lateroapical margin acute ( Fig. 44 View Fig ). Dorsal left sclerite weakly pigmented, reaching apical margin of genitalia, with lateral margin straight, slightly curved near apex; apex oblong ( Fig. 44 View Fig ).

Description. General color brown. Head. Dorsum and gena brown with black spots, small tubercles ( Fig. 42A-B View Fig ). Sulcus formed between frontal suture light yellow. Clypeus and labrum light yellow. Area between clypeus and labrum conspicuous, slender. Compound eyes and antennae brown, with black spots ( Fig. 42B View Fig ). Antennae with short setae.

Thorax. All thoracic terga brown, distally with transversal black band at posterior margin. Pronotum brown, with dark brown spots ( Fig. 42A View Fig ). Mesonotum same as pronotum, but 1.4 times longer; scutellum triangular ( Fig. 42A View Fig ). Metathoracic scutellum ovoid. Coxopleurite circular, rugose. Mesothoracic epimeron irregular in shape, rugose, brown with dark brown spots. Mesothoracic episternum light brown, rugose, with long setae at ventral margin. Metathoracic pleural region dark brown, shiny, rugose, with black spots. Thoracic sterna shiny, rugose, laterally brown, medially dark brown, with light brown spots.

Legs. Anterior leg dorsally brown. Anterior femur dorsally rugose, opaque; ventrally light brown with several black spots, shiny; with long setae at posterior margin ( Fig. 42C View Fig ). Anterior tibia same as anterior femur. Mid femur light posteriorly brown with black spots, and four projections on ventral margin, with the most apical projection conspicuously elongated and enlarged and short setae on dorsal and ventral margins ( Fig.42D View Fig ); ventrally the same, but shiny.Mid tibia same as mid femur, but without projections on ventral margin. Posterior femur concolor with mid femur, in posterior view with conspicuous pointed projections on ventral margin; dorsal and ventral margins with long setae ( Fig. 42E View Fig ); anteriorly the same as posteriorly, but shiny. Posterior tibia same as posterior femur, but anteriorly and posteriorly opaque; with 16 small spines on ventral margin.

Wings ( Fig. 42A View Fig ). Tegmina hyaline, with veins and transversal veins light brown. Posterior wing reaching tergum 7, with apical third of costal area brown; basal and mid thirds and anal area hyaline, with light brow veins.

Abdomen. Abdominal terga shiny, dark brown ( Fig. 42A View Fig ) Terga 3-7 longer than wide, rectangular. Tergum 8 rectangular, 1.6 times wider than long. Tergum 9 dome-shaped, with basal margin straight, lateral and apical margins arched, convex. Tergum 10 same as tergum 9. Cercus with acute apex and short setae. Abdominal sterna laterally brown, medially black, shiny ( Fig. 42F View Fig ). Sternum 7 rectangular, 1.5 times wider than long ( Fig. 43A View Fig ). Sternum 8 rectangular, two times wider than long with basal margin concave ( Fig. 43A View Fig ). Subgenital plate with posterior margin almost straight, medial projection conspicuously emarginated, densely covered by small setae near lateral margin ( Fig. 43A View Fig ). Vomer with base enlarged, lateral margin straight, apex rounded, weakly sclerotized ( Fig. 43B View Fig ).

Genitalia ( Fig. 44 View Fig ). Basal pouch elongated, 2.6 times longer than wide; in dorsal view with left lateroapical margin acute; projection with acute apex, slender. Dorsal left sclerite weakly pigmented, reaching apical margin of genitalia, with lateral margin straight, slightly curved near apex; apex oblong; almost entirely attached to dorsal wall of genitalia.

Variations. The holotype has been stored in alcohol for 111 years and due to this, some of its coloration is paler than that observed in the dry specimen in Fig. 27A View Fig .

Measurements. Body length 40.4-40.6; pronotum 2.9-3.0; mesonotum 3.9-4.2; anterior femur 8.2; mid femur 5.3-5.6; posterior femur 11.7-12.0.

Holotype condition. Good conditions.

Geographical records. Brazil, Minas Gerais: Mariana; Rio de Janeiro: Itatiaia.

Remarks. This species was transferred from Dinelytron due to the presence of diagnostic characters of Prisopoides gen. nov. It can be differentiated from Pe. atrobrunneus sp. nov. by the presence of an elongated and widened projection at the apex of the posterior margin of the mid femur (absent in Pe. atrobrunneus sp. nov.), and

from Pe, brunnescens sp. nov. and Pe. caatingaensis sp. nov. by the abdominal sterna, which is laterally brown and medially black (versus light brown and dark brown in Pe. brunnescens sp. nov. and Pe. caatingaensis sp. nov.).
