Diagnosis

Body predominantly black, except antenna brown testaceous, mandible and ventral surface of scape white; legs brown, except part of coxa, trochanter, tibia and tarsomeres whitish; metasoma dark brown testaceous. Body with short and sparse pilosity, except malar space, part of frons and clypeus with dense and long pilosity. Body predominantly smooth, except part of head rugose; frontal line presente; posterior surface of mesopleuron, metapleuron and propodeum with sparse transverse carinae. Enlarged claw with one row of four bristles; inner margin of 5 th protarsomere with two rows of 21 lamellae and distal apex with 21 lamellae.

Etymology

The name albopictus derives from the Latin words, ‘ albo ’ for ‘white’, and ‘ pictus ’ for ‘colour’. It refers to the white scape.

Description

Female

Apterous, body length 3.67 mm.

COLORATION. Head black ( Fig. 3A–C View Fig ); clypeus whitish, except by central region brown testaceous ( Fig. 3B View Fig ); antenna with scape testaceous, except ventral surface white ( Fig. 3A–B View Fig ), pedicel and 1 st flagellomere brown testaceous and 2–8 flagellomeres brown ( Figs 1A View Fig , 3A View Fig ); mandible whitish ( Fig. 3B–C View Fig ), except teeth brown testaceous; pronotum black ( Fig. 3A, D–E View Fig ), except lateral surface brown testaceous; mesoscutum black ( Figs 3D–E View Fig , 9A View Fig ); legs dark brown black and whitish ( Fig. 3A View Fig ), except apex of coxae, base and apical margin of trochanter, apex of femur and protarsus whitish, and part of protarsomeres brown testaceous; petiole black; metasoma dark brown testaceous.

PUBESCENCE. Head with thin and short pilosity ( Fig. 3B–C View Fig ), except malar space ( Fig. 3B View Fig ) and inner margin of eyes, near to antennal alveolus, with dense pilosity; clypeus with dense pilosity ( Fig. 3B View Fig ); gena, pronotum, mesoscutum, metanotum, mesopleuron, metapleuron and legs with short and sparse pilosity ( Fig. 3 View Fig ); mesoscutellum with fine and sparse pilosity ( Fig. 3D View Fig ); propodeum glabrous; metasoma with short and sparse pilosity.

HEAD. Excavated, smooth, except face partially rugose and granulate ( Fig. 3B–C View Fig ); gena and clypeus smooth, except central region rugose. Antennomere lengths in following proportions: 20:12:32:23:19:15:13:11:10:17; rhinaria present on flagellomeres 6–8 ( Fig. 1A View Fig ). Frontal line present and restricted to near ocelli ( Fig. 3C View Fig ). Ocellar ratio: OL= 8; POL= 5; OOL= 18.

MESOSOMA. Pronotum smooth ( Fig. 3D–E View Fig ); mesoscutum rugose; mesoscutum with lateral pointed apophyses ( Fig. 3D–E View Fig ); mesoscutellum and metanotum smooth; mesopleuron smooth, except small area on posterior surface with some transverse carinae; metapleuron smooth, except posterior surface with transverse carinae; propodeum smooth ( Figs 3D–E View Fig , 9 View Fig ), except for several fine transverse carinae. Dorsal surface of propodeum shorter than posterior (20:30).

LEGS. Protarsomeres in following proportions: 30:7:15:30:53 and enlarged claw (43). Chela, enlarged claw with one row of five bristles ( Fig. 10A View Fig ); inner margin of 5 th protarsomere with two rows of 23 lamellae and about 11 long bristles and distal apex with 34 lamellae.

Remarks

Pareucamptonyx albopictus Martins sp. nov. resembles P. paranaensis Martins sp. nov. by the body predominantly black ( Figs 3 View Fig , 6 View Fig ); ocellar ratio with OL longer than POL and mesoscutum with lateral pointed apophyses ( Figs 3D–E View Fig , 6D–E View Fig , 9A, D, F View Fig ). However, P. albopictus differs by the scape with ventral margin white; flagellomeres 6–8 with rhinaria; head with vertex smooth and with sparse pilosity, malar space, mandible and inner margin of face, near to eye, with dense and long pilosity; mandible with teeth brown, part of clypeus and ventral surface of scape whitish; mesoscutum smooth, except some area rugose ( Fig. 9A View Fig ); metanotum smooth; chela with enlarged claw with one row of five bristles and inner margin of 5 th protarsomere with 23 lamellae, about 11 long bristles and apex with 21 lamellae ( Fig. 10A View Fig ).
