Diagnosis.

Notiospathius curvilineatus sp. n. is distinguished from the remaining described species of the genus by having a combination of the mesopleuron diagonally costate from postero-median to medio-ventral region medially and ventrally, and the first three metasomal tergites sculptured. This species runs to Notiospathius janzeni in Marsh’s (2002) key to Costa Rican species and its Zaldívar-Riverón and De Jesús-Bonilla’s (2010, 2011) extension; however it differs by having the mesososma and first metasomal tergite reddish brown to brown (mesosoma and first metasomal tergite dark brown to black in Notiospathius janzeni ); hind coxa pale yellow, brown apically (hind coxa dark brown or black in Notiospathius janzeni ); and frons striate (frons rugose in Notiospathius janzeni ).

Description.

Female. Colour: Head brown to reddish brown; scape pale yellow with a brown longitudinal stripe laterally; flagellomeres dark brown turning black to apex, apical 9 white; palpi white. Mesosoma and first metasomal tergite reddish brown to brown; second metasomal tergite dark brown, yellow basolaterally; third metasomal tergite yellow, dark brown apically;remaining metasomal tergites brown except the last one which is yellow; ovipositor and sheaths brown to reddish brown. Fore and middle coxae, trochanter and trochantellus pale yellow; femora pale yellow with a median and an apical dark brown transverse bands dorsally; tibiae pale yellow basally, light brown medially and apically, with a dark brown transverse band dorso-basally; tarsi light brown to brown; hind coxa pale yellow, brown apically; trochanter and trochantellus honey yellow; femur pale yellow on basal third, apical two thirds dark brown; tibia pale yellow basally, light brown medially and apically, with a dark brown transverse band dorso-basally; tarsi brown. Wings dusky; veins and stigma dark brown; tegula yellow. Body length: 5.8 mm (lateral view); ovipositor 6.8 mm. Head: Clypeus rugose; face straite; frons striate; vertex striate; temple and gena smooth; eye 1.5 times higher than wide (lateral view); malar space 0.4 times eye height (lateral view); temple 0.2 times eye width (dorsal view); hypoclypeal depression elliptic; ocular-ocellar distance 2.6 times diameter of lateral ocellus; length of scape 1.4 times its width (frontal view); antenna with 35 flagellomeres. Mesosoma: Length of mesosoma 1.9 times its maximum height; pronotum longitudinally costate-coriaceous; pronotal groove wide and slightly scrobiculate; propleuron slightly striate; lateral mesoscutal lobes coriaceous medially, transversally costate along notauli and edges; median mesocutal lobe transversally costate-rugose; notauli wide, deep and scrobiculate, meeting just before scutellum in a longitudinally costate-rugose area; scutellar disc smooth; mesopleural and subalar sulcus discontinuous, the first one deep and scrobiculate and the second one wide, deep and including the striate sculpture of mesopleuron; mesopleuron porcate-slightly coriaceous dorsally, slightly curved, diagonally costate from postero-median to medio-ventral region medially and ventrally; precoxal sulcus wide, deep and including the striate sculpture of mesopleuron, as long as mesopleuron; venter of mesosoma smooth and polished; metapleuron costate ventrally, rugose-aerolate dorsally, slightly coriaceous on anterior first third; propodeum rugose; apical lateral corners without distinct tubercles; spines over hind coxa indistinct. Wings: Fore wing length 4.3 times its maximum width; length of pterostigma 2.8 times its maximum width; vein r 0.2 length of vein 3RSa; vein m-cu antefurcal to vein 2RS; vein 1cu-a distinctly postfurcal to vein 1M; hind wing vein M+CU about 0.4 times length of vein 1M. Legs: hind coxa striate, indistinct tubercule at the base; middle and hind femora slightly coriaceous. Metasoma: First metasomal tergite strongly costate with rugose microsculpture, length 3.1 times its apical width (dorsal view); basal sternal plate (acrosternite) about 0.6 times length of tergum; second metasomal tergite costate with rugose microsculpture; suture between second and third metasomal tergites distinct and sinuate; third metasomal tergite coriaceous on basal half, smooth on apical half; remaining metasomal tergites smooth and polished; ovipositor about 1.8 times length of metasoma.

Male. Unknown.

Variation.

Females: Body length: close to 5.8 mm; ovipositor about 5.8-6.8. Head: Eye 1.4-1.5 times higher than wide (lateral view); scutellar disc slightly coriaceous to smooth.

Metasoma: length of first metasomal tergite 3.1-3.7 times its apical width (dorsal view); ovipositor about 1.6-1.8 times length of metasoma.
