Pterandrus acicularis Munro, 1969: 420.
Body length: 5.09 (4.80-5.30) mm; wing length: 5.68 (5.25-6.15) mm.

Antenna yellow. First flagellomere 2-3 times as long as pedicel. Arista with moderately long rays; ventral rays somewhat shorter and sparser than dorsal rays, especially basally. Frons yellow; with short scattered setulae largely of same color as frons. Frontal setae well developed, occasionally less so. Face yellowish white. Genal seta and setulae dark, well developed. Thorax:
Postpronotal lobe white, without spot. Scutal pattern, ground color pale gray, with streaks and darker markings but without distinct spots or clearly defined stripes, except prescutellar white markings, separate but with pale area in between. Scapular setae dark. Scutellum grayish white, basally without spots, apically with three separate black spots, extending to basal half. Anepisternum completely pale, ventral margin narrowly dark brown; setulae pale except few dark setulae usually present along ventral margin. Legs:
Yellow except where otherwise noted; setation typical for subgenus, mainly dark. Foreleg:
femur anteriorly mainly brownish, only basal and ventral margin yellow, posteriorly largely brown, no distinct bush, only dispersed setulae; ventral setae black. Midleg:
femur anteriorly largely brown, distal end pale; ventrally with dark dispersed setulae, distally somewhat denser but without distinct feathering; tibia broadened; largely brown, with black feathering dorsally along distal 0.9 and ventrally along distal 0.8, anterior part covered by short dark setulae. Hindleg:
femur brown on basal 0.8; at apical 0.25 with longer setulae dorsally and ventrally. Wing:
Bands brownish. Interruption between marginal and discal bands near vein R1 clear and complete; discal band sometimes partly interrupted in discal cell; cubital band free; medial band absent; crossvein R-M opposite middle of discal cell. Apex of vein R1 distal to level of crossvein R-M. Crossvein DM-Cu straight. Abdomen:
Mostly Yellow. Tergites 2 and 4 largely pale gray. Tergite 3 with brownish black transverse band along posterior half. Tergite 5 along anterior margin with isolated brownish patches, posterior margin narrowly black.
epandrium in lateral view with posterior lobe of lateral surstylus straight and elongate.
As male except following characters:
Legs without feathering, yellow, except femora yellowish orange; forefemur posteroventrally with dark pilosity. Discal band not interrupted. Tergite 5 largely pale yellow across posterior half. Oviscape as long as, or longer than, preabdomen. Aculeus at least eight times as long as wide; tip with distinct apical indentation and lateral margin slightly sinuous.
