Review of the genus Dinelytron Gray (Prisopodidae: Prisopodinae: Prisopodini), with a phylogenetic analysis of the genera of the Prisopodini, including the description of a new genus Heleodoro, Raphael Aquino Rafael, Jose Albertino Zoologischer Anzeiger 2020 2020-03-31 285 37 80 8QQLV Heleodoro & Rafael, 2020 Heleodoro & Rafael 2020 [837,946,1349,1369] Insecta Prisopodidae Prisopoides Animalia Phasmida 21 58 Arthropoda genus gen. nov.    Typespecies:  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. 28B; 33A; 39A-Band 42B). Mesothoracic episternum with ventral margin sinuous ( Figs. 28Band 48L). Anterior femur trapezoidal, enlarged, up to 2.3 times longer than wide, with posterior margin slightly or conspicuously sinuous ( Figs. 33A; 39A; 42Cand 49I). Abdominal terga with lateral projections ( Figs. 40Eand 43B). Subgenital plate with posterior margin projected medially ( Figs. 29A; 34A; 40B-C; 43Aand 50D). Basal pouch of male genitalia having acute projection at basal margin; dorsal left sclerite bacilliform in dorsal view ( Figs. 30- 32; 35- 38; 41and 44).   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; 33A; 39A-Band 42B). 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; 33A; 39A-Band 42B). Antenna with setae, surpassing metanotum; scape as long as wide.   Fig. 25.  Dinelytron trimaculatus  sp. nov. _holotype genitalia.

A) habitus of lectotype (pres. desig.), dorsal view; B) vomer of lectotype, ventral view; C) habitus of paralectotype, lateral view. Thorax. Ventro-laterally covered by setae ( Fig. 48L). Pro- and meso-notum granulated, opaque ( Figs. 28A-B; 33A; 39A-B; 48L). Pronotum and proscutum quadrangular, with aperture of pronotal gland conspicuous ( Figs. 28A-B; 33A; 39A-Band 48L). Pronotum with inconspicuous carinae and sulcus ( Figs. 28A-B; 33A; 39A-Band 48L). Mesonotum and mesoscutum rectangular, with conspicuous longitudinal medial carina; scutellum triangular or cordiform ( Figs. 28A-B; 33A; 39A-Band 48L). Metanotum shiny, dark brown ( Figs. 28A; 39Band 2A). Mesothoracic episternum with ventral margin sinuous ( Figs. 28Band 48L). Thoracic sterna rugose ( Fig. 33B). Probasisternum trapezoidal, with apical margin wider than basal margin ( Fig. 33B). Mesobasisternum rectangular, longer than wide ( Fig. 33B). 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; 39A, Dand 42C). Mid femur slender, with all margins sinuous ( Figs. 33Cand 42D). Posterior femur rectangular, with ventral margin sinuous, with spines ( Figs. 28Dand 42E). All tarsomeres with setae, with all margins straight. Wings ( Figs. 28A; 33A; 39A-Band 42A). 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). Abdominal terga with lateral projections. Abdominal sterna shiny, with longitudinal medial sulcus ( Fig. 33A-B). Cercus laterally flattened ( Fig. 40A-B). Vomer Yshaped, arched at base, narrowing towards apex ( Figs. 29B; 34B; 40Eand 43B). Thorn pads semi-ellipsoid, with three to six spines. Subgenital plate not reaching tergum 10, medially with posterior margin projected ( Figs. 29A; 34A; 40B-Cand 43A). Genitalia ( Figs. 30- 32; 35- 38; 41and 44). 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.  Species included:   Prisopoides atrobrunneus  sp. nov.   Prisopoides brunnescens  sp. nov. typespecies (pres. desig.)  Prisopoides caatingaensis  sp. nov.   Prisopoides villosipes  comb. nov.
