Prisopoides View in CoL gen. nov.

Type species: P. brunnescens View in CoL sp. nov. (pres. desig.).

Etymology. From the existing genus Prisopus , with the Greek suffix - oides (resembling), referring to the morphological resemblance of the genus to Prisopus . The genus is a masculine name.

Diagnosis. Head vertex elevated ( Figs. 28B View Fig ; 33A View Fig ; 39A-B View Fig and 42B View Fig ). Mesothoracic episternum with ventral margin sinuous ( Figs. 28B View Fig and 48L View Fig ). Anterior femur trapezoidal, enlarged, up to 2.3 times longer than wide, with posterior margin slightly or conspicuously sinuous ( Figs. 33A View Fig ; 39A View Fig ; 42C View Fig and 49I). Abdominal terga with lateral projections ( Figs. 40E View Fig and 43B View Fig ). Subgenital plate with posterior margin projected medially ( Figs. 29A View Fig ; 34A View Fig ; 40B-C View Fig ; 43A View Fig and 50D). Basal pouch of male genitalia having acute projection at basal margin; dorsal left sclerite bacilliform in dorsal view ( Figs. 30- View Fig 32 View Fig ; 35- View Fig 38 View Fig ; 41 View Fig and 44 View Fig ).

Description _ (only known sex). General coloration variable, with different tones of brown and gray. Head. Opaque, dorsally elevated at vertex; coronal suture conspicuous, deep ( Figs. 28B View Fig ; 33A View Fig ; 39A-B View Fig and 42B View Fig ). Frontal suture inconspicuous, forming an inconspicuous sulcus at frons. Clypeus resembling an anvil. Labrum C-shaped. Compound eyes globose, conspicuously smaller than head ( Figs. 28B View Fig ; 33A View Fig ; 39A-B View Fig and 42B View Fig ). Antenna with setae, surpassing metanotum; scape as long as wide.

Thorax. Ventro-laterally covered by setae ( Fig. 48L View Fig ). Pro- and meso-notum granulated, opaque ( Figs. 28A-B View Fig ; 33A View Fig ; 39A-B View Fig ; 48L View Fig ). Pronotum and proscutum quadrangular, with aperture of pronotal gland conspicuous ( Figs. 28A-B View Fig ; 33A View Fig ; 39A-B View Fig and 48L View Fig ). Pronotum with inconspicuous carinae and sulcus ( Figs. 28A-B View Fig ; 33A View Fig ; 39A-B View Fig and 48L View Fig ). Mesonotum and mesoscutum rectangular, with conspicuous longitudinal medial carina; scutellum triangular or cordiform ( Figs. 28A-B View Fig ; 33A View Fig ; 39A-B View Fig and 48L View Fig ). Metanotum shiny, dark brown ( Figs. 28A View Fig ; 39B View Fig and 2A View Fig ). Mesothoracic episternum with ventral margin sinuous ( Figs. 28B View Fig and 48L View Fig ). Thoracic sterna rugose ( Fig. 33B View Fig ). Probasisternum trapezoidal, with apical margin wider than basal margin ( Fig. 33B View Fig ). Mesobasisternum rectangular, longer than wide ( Fig. 33B View Fig ).

Legs. Anterior and posterior margins of all legs with setae. Anterior femur trapezoidal, enlarged, up to 2.3 times longer than wide, with posterior margin slightly or conspicuously sinuous; dorsally with two parallel longitudinal carinae ( Figs. 33A-B View Fig ; 39A, D View Fig and 42C View Fig ). Mid femur slender, with all margins sinuous ( Figs. 33C View Fig and 42D View Fig ). Posterior femur rectangular, with ventral margin sinuous, with spines ( Figs. 28D View Fig and 42E View Fig ). All tarsomeres with setae, with all margins straight.

Wings ( Figs. 28A View Fig ; 33A View Fig ; 39A-B View Fig and 42A View Fig ). Tegmina elongated ellipsoid, with inconspicuous shoulder pads; subcostal and radial veins close to one other, seeming fused; several transverse veins present. Posterior wing reaching tergum 8, with costal area concolor with tegmina; anal area hyaline or pale, with several transverse veins.

Abdomen. Elongated, slender, widening at tergum 7 towards apex ( Fig. 33A-B View Fig ). Abdominal terga with lateral projections. Abdominal sterna shiny, with longitudinal medial sulcus ( Fig. 33A-B View Fig ). Cercus laterally flattened ( Fig. 40A-B View Fig ). Vomer Yshaped, arched at base, narrowing towards apex ( Figs. 29B View Fig ; 34B View Fig ; 40E View Fig and 43B View Fig ). Thorn pads semi-ellipsoid, with three to six spines. Subgenital plate not reaching tergum 10, medially with posterior margin projected ( Figs. 29A View Fig ; 34A View Fig ; 40B-C View Fig and 43A View Fig ).

Genitalia ( Figs. 30- View Fig 32 View Fig ; 35- View Fig 38 View Fig ; 41 View Fig and 44 View Fig ). Dorsal lobe continuously connected to ventral lobe; dorsal portion covered by small rigid spiny sensilla; ventral portion with digitiform projections. Left posterior process inconspicuous, covered by small spines. Basal pouch external to the genitalia, with conspicuous internal pouchlike subdivision, with acute projection at basal margin. Dorsal left sclerite well pigmented, bacilliform in dorsal view; always directed from anterior portion towards posterior portion of the genitalia; connection to basal pouch external to the genitalia, then remaining internal.
