only very slightly flattened on disc. Fore coxa bare on inner half of anterior surface, except 
near apex. Transverse row of erect median marginal setae of T3 present in both sexes. T5

Discussion. This subgenus is very closely similar to Formosia s.str. but is easily 
and constantly distinguishable and I consider it best to treat it as a valid subgenus. 
It differs from Formosia s.str. by having two sternopleural setae and in having the 
inner anterior half of the fore coxa bare (as in Euamphibolia) and by some other 
more minor and less constant differences such as the presence in most specimens of a 
small but distinct presutural dorsocentral seta (though this seta is most often absent 
in the males of F. (P.) moneta). Pseudoformosia, like Formosia s.str., is confined to 
tropical areas but has a much more restricted distribution than Formosia, as it is 
apparently unrepresented anywhere west of the Moluccas (1.e. in the Oriental Region) 
or in the Bismarck Archipelago or the Solomon Islands. 
As known at present the subgenus is small and contains only four species; it is 
not considered necessary therefore to recognize any species-groups at the present 
time. However, it may be noted that the type-species, F. (P.) moneta, differs from 
the other included species by having the parafrontals and epistome shining metallic 
green or blue, in lacking strong setae on T5 behind the main transverse row, and in 
having the upper eye facets of the male conspicuously enlarged; the other three 
species (listed below) have the parafrontals and epistome non-metallic, possess some 
strong setae laterally on T5 behind the transverse row, and have the male eye facets 
normal. One species (pawper de Meijere) has the entire body very dark brownish 
black with dark brown wings, but the other species more closely resemble typical 
species of Formosva s.str. in having beautiful brilliant coppery green or bluish green 
metallic patterns on the abdomen and green to violet colouring on the thorax. 
Engel (1925 : 357) synonymized Pseudoformosia with Formosia and this generic 
synonymy was presumably accepted by Malloch (1929 : 309), as he placed moneta— 
the type-species of Pseudoformosia—in the genus Formosia. Ina slightly later paper 
Malloch (1930 : 104) wrote that “The two new species [i.e. guadripunctata and 
cingulata] belong to the subgenus Pseudoformosia’, though he did not say how this 
subgenus differed from typical Formosia; however, Malloch’s use of Pseudoformosia 
in subgeneric status means that no new status is involved in the present work. 
Enderlein (1936 : 427) treated Pseudoformosia as a synonym of Formosia, but used 
the latter genus in a very narrow sense (including in it only three species, most of the 
species here included in Formosia s.str. being placed in Pancala Enderlein by Ender- 
lein).
