Diagnosis

Body length 1.5 mm, wing length 1.2 mm. Palpus brownish yellow. Thorax with brown prothoracic sclerites and mesoscutum, otherwise yellow. Postpronotal bristle long. Legs with mid femur in apical 1/3, hind femur in apical 3/4, mid and hind tarsomere 5 brownish, fore tarsomere 5 black, fore tibia and fore tarsomere 1 brownish yellow. Mid femur slender, with 2 short, dark posteroventral spines in basal 1/3, 1 similar anteroventral spine in apical 1/3 and yellow bristle in extreme base. Mid tibia with rows of ventral spinules. Hind femur (viewed laterally) more or less evenly thickened. Hind tibia unmodified. Wing uniformly infuscate. R 2+3 present, about 2.5 times longer than Rs. Distance between apices of R 2+3 and R 4+5 1.2 times longer than distance between apices of R 1 and R 2+3. R 4+5 and M slightly divergent and arcuate in apical part. Halter with elongate black knob constrasting with pale stem. Abdominal glandlike structures present between tergites 3 and 4 and 2 and 3. Terminalia lacking spines, with upper lobe of left surstylus bearing markedly developed surstylar comb. Female unknown.

Distribution

Singapore.

Habitat and seasonal occurrence

The single record of this species was found in a swamp, in December during the rainy season.

Remarks

In Singapore (and the Oriental Region on the whole) this species can be readily recognised by the combination of the uniformly brown scutum and yellow pleura of the thorax. However, the relationships of S. malayensis  are unresolved beyond inclusion within the S. divergens  group.
