Prisopoides  gen. nov.

Type species: P. brunnescens  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. 28BView Fig; 33AView Fig; 39A-BView Fig and 42BView Fig). Mesothoracic episternum with ventral margin sinuous ( Figs. 28BView Fig and 48LView Fig). Anterior femur trapezoidal, enlarged, up to 2.3 times longer than wide, with posterior margin slightly or conspicuously sinuous ( Figs. 33AView Fig; 39AView Fig; 42CView Fig and 49I). Abdominal terga with lateral projections ( Figs. 40EView Fig and 43BView Fig). Subgenital plate with posterior margin projected medially ( Figs. 29AView Fig; 34AView Fig; 40B-CView Fig; 43AView 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 32View Fig; 35-View Fig 38View Fig; 41View Fig and 44View 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. 28BView Fig; 33AView Fig; 39A-BView Fig and 42BView 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. 28BView Fig; 33AView Fig; 39A-BView Fig and 42BView Fig). Antenna with setae, surpassing metanotum; scape as long as wide.

Thorax. Ventro-laterally covered by setae ( Fig. 48LView Fig). Pro- and meso-notum granulated, opaque ( Figs. 28A-BView Fig; 33AView Fig; 39A-BView Fig; 48LView Fig). Pronotum and proscutum quadrangular, with aperture of pronotal gland conspicuous ( Figs. 28A-BView Fig; 33AView Fig; 39A-BView Fig and 48LView Fig). Pronotum with inconspicuous carinae and sulcus ( Figs. 28A-BView Fig; 33AView Fig; 39A-BView Fig and 48LView Fig). Mesonotum and mesoscutum rectangular, with conspicuous longitudinal medial carina; scutellum triangular or cordiform ( Figs. 28A-BView Fig; 33AView Fig; 39A-BView Fig and 48LView Fig). Metanotum shiny, dark brown ( Figs. 28AView Fig; 39BView Fig and 2AView Fig). Mesothoracic episternum with ventral margin sinuous ( Figs. 28BView Fig and 48LView Fig). Thoracic sterna rugose ( Fig. 33BView Fig). Probasisternum trapezoidal, with apical margin wider than basal margin ( Fig. 33BView Fig). Mesobasisternum rectangular, longer than wide ( Fig. 33BView 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-BView Fig; 39A, DView Fig and 42CView Fig). Mid femur slender, with all margins sinuous ( Figs. 33CView Fig and 42DView Fig). Posterior femur rectangular, with ventral margin sinuous, with spines ( Figs. 28DView Fig and 42EView Fig). All tarsomeres with setae, with all margins straight.

Wings ( Figs. 28AView Fig; 33AView Fig; 39A-BView Fig and 42AView 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-BView Fig). Abdominal terga with lateral projections. Abdominal sterna shiny, with longitudinal medial sulcus ( Fig. 33A-BView Fig). Cercus laterally flattened ( Fig. 40A-BView Fig). Vomer Yshaped, arched at base, narrowing towards apex ( Figs. 29BView Fig; 34BView Fig; 40EView Fig and 43BView Fig). Thorn pads semi-ellipsoid, with three to six spines. Subgenital plate not reaching tergum 10, medially with posterior margin projected ( Figs. 29AView Fig; 34AView Fig; 40B-CView Fig and 43AView Fig).

Genitalia ( Figs. 30-View Fig 32View Fig; 35-View Fig 38View Fig; 41View Fig and 44View 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.
