Gonatopus townesi Olmi, 1984: 1748 . Female, holotype. Brazil: Mato Grosso, Sinop (EMUS, examined through photographs).

Diagnosis

Apterous, body length 2.0 mm in holotype and 3.5–3.9 mm in the additional material.

Body predominantly black, except palpomeres, mandible and antenna testaceous; clypeus and part of face brown testaceous; lateral margin of pronotum testaceous; legs brown testaceous, except apical margin of procoxa, protrochanter and chela whitish; metasoma dark brown testaceous. Head glabrous, except dense and long pilosity on part of face, malar space and clypeus ( Fig. 7B–C ); legs and metasoma with sparse and short pilosity. Frontal line absent ( Fig. 7C ); antenna with rhinaria on flagellomeres 6–8 ( Fig. 1E ), occipital carina absent ( Fig. 7C ). Mesoscutum rugose, without lateral pointed apophyses ( Figs 7D , 9E ); propodeum with several transverse carinae ( Fig. 7D ). Enlarged claw with four bristles and 5 th protarsomere with inner margin with two rows of 10 lamellae and six long bristles (in holotype) or two rows of 14 lamellae (in additional material); distal apex with about 12 lamellae (in holotype) or about 38 lamellae (in additional material).

Distribution

Remarks

Pareucamptonyx townesi resembles P. zulianus as the mesoscutum lacks lateral pointed apophyses ( Fig. 4D–E ). However, P. townesi differs in the absence of a frontal line and the inner margin of the 5 th protarsomere with 10–14 lamellae and six long bristles ( Fig. 10B–C ; Olmi & Virla 2014: fig. 215e).
