Discothyrea kamiteta

Discothyrea kamiteta has been collected from leaf litter in various habitats, such as primary forest, limestone forest and secondary forest.

Identification
Kubota and Terayama (1999) - Total length of workers slightly greater than 2 mm. Body color reddish brown. Mandible covered by the protruding clypeal shelf. Antenna 9-segmented. Eye large, prominently protruding. Mesosoma 1.45 times as long as high in profile. Gastral tergites with distinct punctures that are moderately spaced.

This species similar to Discothyrea sauteri, but a little larger, antenna 9-segmented, eye large and prominently protruding, mesosoma shorter and higher than in sauteri, punctures on gastral tergites deeper and more distinct, and spaces between punctures wider.

Antenna 9-segmented; scape 2.9 times as long as maximum width, basal 1/3 very weakly angulate; 2nd segment slightly wider than long; 3rd to 8th segments each distinctly wider than long; terminal segment large, 2.0 times as long as wide. Median lobe broadest at midlength, forming lateral dull angle; maximum width 3.3 times its width of anterior end, and 2.0 times its width of posterior end; posterior end of median lobe opened. Eye large, prominently protruding, with hairs. Mesosoma high and short, 1.45 times as long as high, with relatively weakly convex dorsum in profile; posterodorsal corner of propodeum forming an obtuse angle. Petiole high, 1.7 times as long as high, with strongly convex dorsal margin in profile; node in dorsal view rectangular, 0.5 times as long as wide, with parallel anterior and posterior margins; anterolateral corners forming an distinct angle. Subpetiolar process with convex ventral margin. Head and mesosoma coarsely punctate; the punctures ca. 0.02-0.03 mm in diameter. propodeum coarsely punctate. First gastral tergite with distinct punctures that are moderately spaced; the punctures ca. 0.02 mm in diameter; interspaces microreticulate. Second and third gastral tergites microreticulate and impunctate. Antennal scape strongly microreticulate and impunctate. Body including head covered with pubcences (TJS - pubescences???) coarsely. Body color reddish brown; legs yellowish brown.
