DIAGNOSIS — This species is characterized by s4 ca. 75% as long as distance between its base and the base of z5; j4, j6 and J2 shorter than a third the distance between bases of their respective homologues of both sides, peritreme extending beyond base of j3 and Jv4 present.

FEMALE — (11 specimens measured).

One pair of metapodal shields; caudoventral setae smooth and sharp­tipped.

Chelicera — Movable digit 35(35–36) long, with 1 large tooth and 3 small teeth; fixed digit 30(30–31) long, with 11 teeth and a discernible pilus dentilis.

ETYMOLOGY — The epithet parahavu refers to similarity between this new species and T. havu .

REMARKS — Ueckermannseius bundibugyoensis Moraes, Zannou & Oliveira , sp. nov. is similar to this new species, but it differs by having j4, j6 and J2 longer, each at least half as long as distance between bases of their respective homologues. Ueckermannseius havu , U. macrosetosus and U. neohavu Moraes, Zannou & Oliveira , sp. nov. also resemble this new species, but they differ by having shorter peritreme (not reaching j3) and longer Z5. The first 2 species further differ by having knobbed macrosetae on leg IV, whereas the last species further differs by having some striation on posterior half of dorsal shield and anterior third of ventrianal shield, in addition U. havu differs by lacking Jv4. Ueckermannseius saltus ( Denmark & Matthysse) is also similar to this new species, but differs by having most setae near the margin of the dorsal shield similar in length.
