Diagnosis

Body predominantly black, except part of antenna, pronotum, legs and metasoma brown testaceous. Head with short and sparse pilosity except on malar space with dense and long whitish pilosity; pronotum, mesosoma, legs and metasoma with short and sparse pilosity. Head rugose, except gena smooth; pronotum smooth; mesopleuron and metapleuron smooth, except with transverse carinae on posterior surface; mesoscutum with two lateral pointed apophyses; propodeum smooth and with transverse carinae. Enlarged claw with one row of seven bristles on inner margin; inner margin of 5 th protarsomere with two rows of about 23 lamellae and four long bristles, apex with about 23 lamellae.

Etymology

Description

Female

Apterous, body length 5.5 mm.

COLORATION. Head black, except antenna with scape brown testaceous, pedicel and flagellomeres brown (Fig. 6A–C); mandible whitish (Fig. 6B); pronotum black, except lateral surface testaceous; mesoscutum black (Fig. 6A, D–E); legs predominantly brown testaceous and some regions darkened (Fig. 6A); tarsomeres testaceous and enlarged claw whitish; petiole black; metasoma predominantly brown testaceous and some regions darkened (Fig. 6A).

PUBESCENCE. Body with sparse and short pilosity, except malar space with dense pilosity (Fig. 6); clypeus with fine pilosity (Fig. 6B–C); mesoscutum with short pilosity (Fig. 6D–E); metanotum with sparse pilosity (Fig. 6D–E); legs with dense and sparse pilosity (Fig. 6A); and metasoma with erect setae only on apical portion.

HEAD. Excavated, rugose, except gena smooth (Fig. 6B–C). Palpomeres formula 6:3. Antennomeres in following proportions: 35:7:55:36:30:24:18:17:14:23. Flagellomeres 6–8 with rhinaria (Fig. 1D). Frontal line present only near anterior ocellus (Fig. 6B–C). Ocellar ratio: OL = 8; POL = 5; OOL = 23.

MESOSOMA. Pronotum smooth (Fig. 6A, D–E); mesoscutum smooth, except for longitudinal and incomplete carina (Fig. 6D–E); mesoscutum with two lateral pointed apophyses (Fig. 9F). Mesoscutellum rugose and with sparse longitudinal carinae (Fig. 9D, F) and metanotum smooth (Fig. 6D–E); mesopleuron and metapleuron smooth, except posterior surface with transverse carinae (Fig. 6D); propodeum smooth and with transverse carinae (Fig. 6D–E).

LEGS. Protarsomeres in following proportions: 45:10:22:42:72 and enlarged claw (68). Chela enlarged claw with one row of seven bristles on inner margin (Fig. 10D); inner margin of 5 th protarsomere with two rows of about 23 lamellae and four long bristles, apex with 23 lamellae.

Remarks

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