Tribe Arthrosolaenomeridini Hoffman, 1976

Arthrosolaenomeridini Hoffman, 1976: 171–183 ; Hoffman, 1980: 151.

Diagnosis. Arthrosolaenomeridini males differ from others Chelodesminae males by the combination of the following characteristics: presence of a row of setae 2 + 2 at the apex of the head ( Fig. 29A); presence of two pairs of ventral projections in the fifth sternite; presence of lateral macrosetae, in mesal aspect, on gonocoxae ( Figs 32E–F); laminated telopodite with a cingulum on the lateral margin ( Figs 34A–C); prefemoral process of the gonopod long and thin ( Figs 33B–E).

Descriptive notes. Body length between 39−76 mm. Gonopod: composed of a basal portion (gonocoxae), containing lateral macrosetae; and a distal portion (telopod) divided into two well-developed narrow branches: the external branch (solenomere) presented as a single branch containing a variable-position cingulum and an evident spermatic groove, and the internal branch (prefemoral process) varying in size and format according to genera.

Distribution. The tribe is distributed in Brazil in the northern region (states of Pará and Tocantins), central-west region (states of Goiás, Mato Grosso and Mato Grosso do Sul) and southeast (state of São Paulo).
