description: Saltadorus gen. nov.
(Figs. 9–10)
Type-species: Saltadorus blahniki sp. nov.
Coloration: Body light brown dorsally and ventrally. Forewing translucent, light brown.
External morphology: Head short, crown not produced anteriorly; transocular width subequal to pronotum width; coronal suture visible; crown surface with faint longitudinal carinae medially, these arching more laterally, and grading into coarser transverse carinae at anterior margin of head; crown slightly concave; anterior margin of head with numerous transverse carinae; transition from crown to face angled; lateral frontal suture not reaching ocellus; ocelli medium sized, 1.5x to 2.0x their own diameter distant from eye, positioned posterodorsad of anterior margin; eye with mesal margin entire. Antennal ledges absent. Clypellar suture complete. Clypellus tapering apically, following natural curve of gena, tumid in lateral view. Gena incised laterally; single fine erect seta present, close to lateral frontal suture. Lorum width much narrower than clypellus near base, close to lower genal margin. Frontoclypeus shagreen, shorter than wide, relatively flat in lateral view.
Pronotum texture shagreen on anterior 1/3, with transverse ridges and furrows on posterior 2/3; with distinct lateral carina. Scutellum not inflated.
Forewing rounded apically; macropterous; outer anteapical cell truncate; inner anteapical cell open; corium without extra crossveins; with crossvein between A1 vein and claval suture; appendix restricted to anal margin.
Profemur AM1 present; intercalary row with 12–14 setae; row AV with ~8 relatively long setae, finer near base and thicker toward apex of row. Protibia anterodorsal margin rounded; dorsal macrosetae 1+4. Metafemur setal formula 2+2+1. Metatarsomere I longer than metatarsomeres II and III combined; with 2 platellae between AV and PV; PV seta acuminate.
Male genitalia: Pygofer length twice the height; dorsally incised to base; with several rows of short macrosetae posterodorsally; with lateral inner processes arising dorsally from base. Valve subtriangular. Subgenital plate subtriangular, elongated; outer lateral margin convex in ventral view; excavated along inner margin, plates widely separated; without macrosetae along margin; with few short setae at extreme apex. Connective short, without stem; articulated to aedeagus; anterior arms separated. Style preapical lobe short, rounded; apophysis very short.Aedeagus without processes; gonopore apical; gonoduct sclerotized, extending anteriorly out of atrium. Phragma membranous, forming pair of setose bulbs next to aedeagal shaft and pair of subtriangular flaps beside shaft. Segment X very long, sclerotized laterally throughout length; sclerotized dorsally at apex; at apex, sides extended ventrally to form lobe-like processes.
Female terminalia: Female unknown.
Etymology: The new genus is named after the Spanish word for jumper, saltador. The name of the new genus is a masculine noun.
Diagnosis: The new genus can be distinguished by the short head; angled transition of crown to face with numerous transverse carinae; male pygofer with pair of lateral inner processes arising dorsally and extending beyond pygofer apex, incised dorsally at base; segment X of anal tube very long, sclerotized laterally and with ventral extensions at apex; and the unique shape of subgenital plates and aedeagus.
Notes: The new genus is similar to Brincadorus sp., as they both have short heads, with the frontal region of the crown angled and anterior margin with numerous transverse carinae, and the subgenital plates widely separated with median margins excavated and without macrosetae along the lateral margin. However, the new genus can be distinguished by the presence of a very long inner process on the pygofer arising dorsally near the base, extending ventroapically, and surpassing the pygofer apex (as opposed to the shorter dorsal processes in Brincadorus which arise medially and are bifurcate apically), the subgenital plates not extending dorsally along the pygofer sides (as in Brincadorus), the unique shape of the aedeagus with the sclerotized gonoduct extended out of the atrium. The new genus also resembles Caruya, as they share the elongated male pygofer with lateral processes and the aedeagus without apical processes. However, the new genus can be distinguished by the pygofer with internal processes instead of external, and the subgenital plate widely separated and elongated, as opposed to rounded and lobate in Caruya.
