Description

Bolton (2000) - TL 2.0-3.0, HL 0.74-0.79, HW 0.48-0.55, CI 65-73, ML 0.12-0.13, MI 15-18, SL 0.35-0.46, SI 73, PW 0.30-0.37, AL 0.80-0.92 (measurements after Terayama, Lin, & Wu, 1996). Among the leptothrix-group members of this region formosimonticola has the following combination of characters.

1 Leading edge of scape without freely projecting hairs; all hairs on the leading edge small, decumbent to appressed and directed toward the apex of the scape.

2 With head in profile simple suberect to erect hairs are present on the dorsum between the highest point of the vertex and the occipital margin; such hairs are absent from clypeus to highest point of vertex.

3 With head in full-face view upper scrobe margin to level of eye without freely laterally projecting hairs; lateral margin of occipital lobe, behind level of eye, with about 4 freely laterally projecting straight simple hairs.

4 Dorsal surface of pronotum, as well as mesonotum, with erect long simple hairs present.

5 Dorsal (outer) surfaces of hind tibiae without freely projecting simple hairs; all hairs present are short, decumbent and directed apically.

6 Propodeal lobes (= metapleural lobes) low and rounded, lamellate, not produced into long acute triangular teeth or spines.

7 With petiole in profile the lateral spongiform lobe extends forwards almost to the level of the anterior face of the node.

Type Material

Bolton (2000) - Holotype worker and paratype workers and queens, TAIWAN: Taitung Hsien, Yenping, 29.vii.1992 (C. -C. Lin); paratype workers, same locality but 29-30.vii.1992 (C. –C. Lin) (National Institute of Agro-Environmental Sciences, National Taiwan University, Taiwan Agricultural Research Institute) [examined].
