Diagnosis

Body predominantly brown testaceous and with fine and short pilosity; head rugose, except part of face and vertex smooth; frontal line and occipital carina absent; flagellomeres 5–8 with rhinaria; mesoscutum without lateral pointed apophyses; propodeum with several irregular transverse carinae. Enlarged claw with one row of five bristles, and 5 th tarsomere with inner margin with one row of six lamellae and apex with about 10 lamellae.

Etymology

The new species is named in honor of Dra Alice Fumi Kumagai, an entomologist of the Universidade Federal de Minas Gerais, Belo Horizonte, Brazil, for her dedication to the study of Neotropical Ichneumonidae .

Description

Female

Apterous, body length 3.47 mm.

COLORATION. Head brown testaceous ( Fig. 4A–C ), except clypeus brown; antenna with scape and pedicel brown testaceous ( Fig. 4A–B ), except flagellomeres brown ( Fig. 4A ); pronotum brown testaceous ( Fig. 4B–C ), except one transverse black band; mesosoma brown testaceous ( Figs 4D–E , 9C ), except mesoscutum, and posterior surface of metapleuron and propodeum black; legs brown testaceous ( Fig. 4A ), except apex of procoxa, protibia and part of 3 rd, 5 th and enlarged claw whitish; petiole black; metasoma brown testaceous.

PUBESCENCE. Body with sparse and short pilosity ( Fig. 4A–D ), except head with fine pilosity; clypeus with dense pilosity ( Fig. 4B ); propodeum glabrous; metasoma with dense pilosity on last tergum and sternum.

HEAD. Excavated, rugose, except part of face and vertex smooth ( Fig. 4B–C ); clypeus smooth; gena smooth, anterior surface near to malar space granulate ( Fig. 4B ). Palpomere formula 6:3. Antennomeres in following proportions: 21:15:40:23:21:20:16:14:14:20. Flagellomeres 5–8 with rhinaria ( Fig. 1B ). Frontal line absent. Ocellar ratio: OL = 8; POL = 5; OOL= 18.

MESOSOMA. Pronotum smooth ( Figs 2A , 4D–E ); mesoscutum rugose and with irregular longitudinal carinae, without lateral pointed apophyses ( Figs 4D–E , 9C ); mesoscutellum smooth ( Fig. 4D–E ); metanotum smooth; mesopleuron smooth, except posterior surface with transverse carinae; metapleuron smooth, except transverse carinae on posterior surface; propodeum with several irregular transverse carinae ( Figs 2D , 9B ).

LEGS. Protarsomeres in following proportions: 32:7:11:27:45 and enlarged claw (43). Chela enlarged claw with one row of five bristles, 5 th tarsomere with inner margin with one row of six lamellae and apex with about 10 lamellae ( Figs 2C , 10B ).

Remarks

Pareucamptonyx kumagaiae Martins sp. nov. resembles P. niger Martins sp. nov. due to the rhinaria on flagellomere 5–8; mesoscutellum without lateral pointed apophyses; and by the number of lamellae on the inner margin of the 5 th protarsomere. However, P. kumagaiae differs by the body predominantly brown testaceous; frontal line absent; mesoscutum rugose, with irregular longitudinal carinae ( Fig. 9B ); chela with inner margin of the 5 th protarsomere with one row of six lamellae and three long bristles ( Fig. 10B ).
