Diagnosis

Body predominantly black, except part of antenna, pronotum, legs and metasoma brown testaceous and chela white. Head with short and sparse pilosity, except gena glabrous; pronotum and legs with short and sparse pilosity; head rugose, except vertex partially smooth and clypeus granulate; gena smooth, except region near to malar space granulate; occipital carina absent; frontal line incomplete; pronotum, mesoscutum, mesoscutellum and metanotum smooth; mesoscutum without lateral pointed apophyses; mesopleuron and metapleuron smooth, except posterior surface with some transverse carinae; propodeum smooth and with many sparse transverse carinae. Enlarged claw with one row of five bristles; inner margin of 5 th protarsomere with five lamellae and distal apex with 17 lamellae.

Etymology

The species name comes from the Latin word ‘ niger ’ for ‘black’. It refers to the black colour of the body.

Description

Female

Apterous, body length 4.25 mm.

COLORATION. Head black ( Fig. 5A–C View Fig ), except antenna with scape and pedicel brown testaceous and flagellomeres 1–5 brown ( Fig. 5A View Fig ); mandible black, except teeth brown testaceous ( Fig. 5B View Fig ); pronotum black, except lateral surface testaceous ( Fig. 5D–E View Fig ); mesoscutum black ( Fig. 5D–E View Fig ); legs dark brown, except protarsomeres brown testaceous and chela white; petiole black; metasoma dark brown.

PUBESCENCE. Head with fine and sparse pilosity ( Fig. 5B–C View Fig ); clypeus with short pilosity ( Fig. 5B View Fig ); gena predominantly glabrous and with sparse pilosity; pronotum with sparse and short pilosity ( Fig. 5D–E View Fig ); mesoscutum, mesoscutellum and metanotum glabrous ( Fig. 5A, D–E View Fig ); legs with short and sparse pilosity ( Fig. 5A View Fig ); mesopleuron and metapleuron with sparse and short pilosity ( Fig. 5D View Fig ); propodeum glabrous; metasoma with short and sparse pilosity.

HEAD. Excavated, rugose ( Fig. 5B–C View Fig ), except vertex partially smooth, clypeus granulate ( Fig. 5B View Fig ); gena smooth, except region near malar space granulate; vertex granulate ( Fig. 5C View Fig ). Palpomeres formula 6:3. Antennomeres in following proportions: 23:15:41:22:23:20:17:14:12:19. Flagellomeres 5–8 with rhinaria ( Fig. 1C View Fig ). Frontal line complete ( Fig. 5C View Fig ). Ocellar ratio: OL= 8; POL= 6; OOL= 18.

MESOSOMA. Pronotum, mesoscutellum and metanotum smooth ( Fig. 5D–E View Fig ); mesoscutum predominantly smooth ( Fig. 9C View Fig ), except some longitudinal carinae on lateral surface; without lateral pointed apophyses. Mesopleuron and metapleuron smooth, except posterior surface with some transverse carinae; propodeum smooth with many sparse transverse carinae ( Figs 5D–E View Fig , 9C View Fig ).

LEGS. Protarsomeres in following proportions: 32:8:18:27:48 and enlarged claw (50). Chela enlarged claw with one row of five bristles ( Fig. 10C View Fig ); inner margin of 5 th protarsomere with five lamellae and distal apex with one group of 17 lamellae ( Fig. 10C View Fig ).

Remarks

The right antenna of the holotype lacks flagellomeres 6–8 and the left antenna lost its pedicel and flagellomeres. Therefore, measurements and description of the coloration were made from the paratype. Pareucamptonyx niger Martins sp. nov. resembles P. kumagaiae Martins sp. nov. due to its mesoscutellum without lateral pointed apophyses; flagellomere 5–8 with rhinaria; 5 th protarsomere with reduced number of lamellae and number of bristles of the enlarged claw. However, P. niger differs by the body predominantly black or brown ferruginous; frontal line complete; mesoscutum predominantly smooth ( Fig. 9C View Fig ), except some longitudinal carinae on lateral surface; chela with inner margin of the 5 th protarsomere with one row of five lamellae and two long bristles ( Fig. 10C View Fig ).
