Genus Microananteris Lourenço, 2003

TYPE SPECIES. — Microananteris minor Lourenço, 2003 .

REVISED DIAGNOSIS. — Small scorpions, when compared with the average size of a large number of species of micro-buthid genera; the total length of the three known species ranges from 13.07 to 14.00 mm in total length (see Table 1). Microananteris is characterized among several micro-buthoids and in particular in relation to the genus Ananteris Thorell, 1891 by the presence of very small pectines, with the most distal tooth rounded and the most proximal absent ( Fig. 2 ); the total number of teeth ranges from 10 to 11 in both sexes; the structure of the peg sensillae of the pectines is distinct, showing a rounded structure instead of the spatula-like structure observed in Ananteris species. Spiracles have a semi-oval shape. The sternum is subpentagonal. The Telson is more to globular in shape and the aculeus is short. Trichobothriotaxy: orthobothriotaxy type A-β ( Vachon 1974, 1975). Tibial spurs developed on leg IV but reduced on leg III.

The species of the genus Microananteris are exclusively known from humid forests of French Guiana and correspond to possible endemic elements of the soil fauna.
