Description. Body length 2.15–2.25 mm, glossy, with sparse and erect golden setae; head and pronotum light brown, elytra, abdomen, legs and antennae yellowish brown, maxillary palpi yellow.

Head 1.1 times as wide as long, with large frontal rostrum, antennal tubercles well-defined, rostral apex with deep triangular depression between antennal tubercles; eyes with 13–15 facets; maxillary palpi ( Fig. 9 View FIGURES 8 – 12 ) long, their segment I minuscule, II with small inner tooth, III pedunculate, lacking lateral spine, partly with wrinkled surface; antennae very long, scape more than seven times as long as pedicel and nearly three times as long as terminal antennomere, slightly shorter than funicule, antennomeres III–VII elongate, club foursegmented, VIII rhomboic, slightly longer than wide, IX 1.2 times as wide as long, X 1.7 times as wide as long, terminal antennomere pointed at apex, 1.65 times as long as wide and three times as long as X.

Pronotum as long as wide, 1.25 times as wide as head, widest in apical third, lateral foveae large, slightly setose.

Legs long, protrochanter with two spines, basal spine longer and more robust than apical one, almost as long as single basal spine on profemora.

Abdomen 1.6 times longer than elytra.

Aedeagus as in Figs. 13, 14 View FIGURES 13 – 20 .

Remarks. Anagonus fracticornis is closely allied to A. spinipalpis sharing with this species a very long scape, but is readily separated by the shape of third segment of maxillary palpus which lacks a lateral protuberance.

Biology. All recent material was collected by sifting in primary forest.
