Ceratitis (Pterandrus) argenteostriata De Meyer & Freidberg
Body length: 4.42 (3.70-5.25) mm; wing length: 4.88 (4.30-5.45) mm.

Antenna yellow. First flagellomere 2-3 times as long as pedicel. Arista with short to moderately long rays; ventral rays shorter and sparser than dorsal rays basally. Frons white, dorsal part more yellow, rarely completely yellow; with short scattered setulae distinctly darker than frons. Frontal setae well developed. Face whitish. Genal seta and setulae dark, well developed. Thorax:
Postpronotal lobe white anteriorly, with large dark area posterior to postpronotal seta. Scutal pattern:
ground color black, microtrichose areas with silvery shine, forming two (pairs) distinct vittae; prescutellar white markings separated by paler brownish area. Scapular setae dark, in one specimen medial scapular pale. Scutellum basally yellowish white, without black spots, apically with three joined black spots, extending to basal 0.33, weakly incised. Anepisternum on ventral half brown or black; setulae pale. Legs:
Yellow except where otherwise noted; setation typical for subgenus, mixed pale and dark. Foreleg:
femur anterodorsal half black, posteriorly largely black except ventrobasally, with dispersed dark setulae along entire length but without distinct bush, posterodorsal setulae longer; ventral setae dark. Midleg:
femur extensively darkened anteromedially, with silvery shine; ventrally with black feathering along distal half, basally with few dispersed long pale or dark setulae; tibia moderately broadened; largely blackish except basally, silvery shine when viewed from certain angle; with black feathering along distal 0.8 dorsally and 0.75 ventrally, with second row of short black setulae anterior to ventral row. Hindleg:
femur at apical 0.33 with long thin setae dorsally and ventrally. Wing:
Bands brown. Marginal band broadly separated from discal band around apex of vein R1 and with large marginal hyaline spot around apex of vein R2+3; cubital and medial bands free; crossvein R-M proximal to middle of discal cell. Apex of vein R1 distal to level of crossvein R-M. Crossvein DM-Cu oblique anterobasally. Abdomen:
Predominantly yellow. Margin between tergites 1 and 2 largely brown. Tergites 2 and 4 with pale gray band along posterior half. Tergite 3 largely brown. Tergites 4 and 5 with brown band along anterior half, sometimes interrupted in middle. Posterior margin of tergite 5 narrowly brown. Setation typical for subgenus.
Male epandrium in lateral view with posterior lobe of lateral surstylus slender and pointed.
As male except following characters:
Antenna darker. Crossvein DM-Cu oblique posterobasally. Legs without feathering, setulae dark; femora darker brown on median part; forefemur posteroventrally with dark setulae. Oviscape slightly shorter than preabdomen. Aculeus at most five times as long as wide; tip pointed and lateral margin straight.
