Description. Length 2.8–2.9 mm. Body very shiny and brown, pronotum brown-reddish, basal free urotergites 1st and 2 yellow-reddish with brown-reddish median stain, pygidium yellow-brown, antennae brown with 8th to 10th antennomeres brown-reddish and 11th reddish, legs yellow. Eyes shorter than temples. 2nd antennomere shorter than 1st, 3rd a little longer than 2nd, 4th antennomeres to 7th longer than wide, the 3 following antennomeres as wide as long, 11th as long as the preceding 2 antennomeres together. Reticulation of the body absent. Punctuation of the head very superficial and missing on the longitudinal median band. Granularity of the pronotum evident and close, those of the elytrae protruding, also close. Granularity of the 2 basal free urotergites sparse and absent on the basal half, urotergites free 3rd and 4th with granules only to the posterior border, 5th free urotergite of the male with 5 salient carinae near the posterior border, the median carinae more salient than lateral ones.Aedeagus figs 11–12, spermatheca fig. 13, labium with labial palpus fig. 14, maxilla with maxillary palpus fig. 15.

Comparative notes. This new species is the 2nd of the genus Aloconota Thomson for Australia after the cosmopolitan Aloconota sulcifrons ( Stephens, 1832) . The aedeagus and habitus is similar to A. inaequalis Cameron, 1944 , from India, of which I have examined the male holotype thus labeled: Ghum Distr., Rongdong Valley, V-VI.1931, Aloconota inaequalis Cam. , Type. The new species differs as follows: the yellow-reddish base of the abdomen is stained brown-reddish (abdomen entirely brown in inaequalis ); the elytrae, measured from the humerus to the external posterior angle, are as long as the pronotum (much longer than the pronotum in inaequalis ); the apex of the aedeagus is largely oval, ventrally viewed, (apex of the aedeagus blunt narrow in inaequalis ). The female inaequalis is not known.

Etymology. The name of the new species means “stained abdomen”.
