Fig. 11
), segment I minuscule, II with small inner tooth, III pedunculate at base, with large lateral spine, lacking wrinkled surface; antennae very long, reaching middle of abdomen, scape about seven times as long as pedicel and 2.15 times as long as terminal antennomere, slightly shorter than funicule, antennomeres II–VII elongate, club four-segmented, VIII rhombic, slightly longer than wide, IX and X about as long as wide, terminal antennomere pointed at apex, about 2.7 times as long as wide and about four times as long as X.
Pronotum about as long as wide, 1.15 times as long as head, widest before middle, each lateral fovea prolonged anteriorly by deep sulcus.
Legs long, protrochanter and profemora with long, subequal and outwardly curved basal spines.
Abdomen 1.4 times as long as elytra, first visible tergite (tergite IV) slightly longer than second (tergite V).
Remarks.
Anagonus spinipalpis
is readily distinguished from its congeners by its entirely dark brown colour, and the presence of a lateral protuberance on the third maxillary palpus as well as with lateral fovea prolonged anteriorly by deep sulcus
Biology.
Both specimens were sifted in virgin humid forest and extracted by Berlese.
Etymology.
The name of the new species refers to the presence of the lateral protuberance on the third segment of maxillary palpi.
