Fig. 8. Spathulathrombium myloriense sp. n. A, Crista and eyes (X 200); B, palpal tibia 
and tarsus (X 200); C, front tarsus and metatarsus (X 200); D, dorsal setae (X 375). 
Genus Microrromepipium Haller, 1882 s.str. 
Milbenf. Wurtemb., 1882. 
Genotype. M. pusillum Hermann, 1804. 
Manriquia Boshell and Kerr, 1942 (in part) Rev. Acad. Columbiana Ci. Ex., 5, 
110-127. 
Microtrombidium Boshell and Kerr, 1942 zbid. (in part). 
As in the subfamily but restricted to those in which the legs are not, or not 
much longer than the body and in which the dorsal setae, even if of two different 
lengths, are pennate or as slender rods with long ciliations. Palpal tibia with or 
without accessory claw, and without or with one or two external spines. 
The members of this genus are very difficult to separate, and the specific charac- 
ters lie principally in the dimensions of the front tarsi and metatarsi and in the 
lengths and structure of the dorsal setae. In reviewing this genus, all my old 
material has been restudied more carefully and, with more material before me, 
it is evident that several species are synonymous and are here sunk. 
The three species barringunense Hirst, retentus Banks and westralense 
Wom. are herewith removed from Microtrombidiwm and will be later allocated: 
to their proper position.
