Diagnosis. Andanus tambopixunensis is easily separated from other species of the genus by lack of a transverse medial band on the pronotum and orange marks on crown, subgenital plate mesal margin sinuate and excavated toward apex, style anterolateral lobe rounded, style apophysis without lateral projection, and aedeagus with pair of long processes arising near apex and paralleling shaft.

Description. External morphology. Body coloration yellowish. Face entirely yellowish or with few orange specks; anteclypeus and gena yellowish. Pronotum yellowish, wider than long and slightly protuberant in lateral view. Forewing with membrane hyaline, anal and Pcu veins bright yellow, remainder of veins dull yellow. Dorsum of abdomen diffuse brown medially, venter yellowish, terminalia light brown with black or pale macrosetae ( Figs 1–3 ).

Male genitalia. Pygofer elongate and rounded posteriorly without process, macrosetae on distal third of disk separated from posterior margin ( Fig. 4 ). Valve acutely angulate posteriorly. Subgenital plate mesal margin deeply incised on distal third ( Fig. 5 ). Connective stem 1.7x longer than arms. Style with medial cleft separating broad, bilobed base from medial lobe and apophysis; medial lobe digitiform; apophysis with triangular projection near mid-length, long with apex curved and blunt ( Fig. 6 ). Aedeagus curved dorsad with long lateral processes closely appressed to shaft, with additional pair of short dorsopreapical spines directed anterad and single minute spine ventroapically ( Figs 7–8 ).
