Herrera-Flórez, Andrés Fabián, 2018, Three new species of Grotea Cresson (Hymenoptera: Ichneumonidae: Labeninae) from Colombia, Zootaxa 4444 (2), pp. 195-200 : 197-200

Grotea cundinamarquesa sp. n.

(Figs 9–14)

Material examined. Holotype: female, COLOMBIA: Cundinamarca, Silvania : 4°24´21´´N 74°23´24´´ W 1470 m. alt., 7 agosto 1988, leg. G.Venegas ( UNAB).

Diagnosis. Head in dorsal view with gena rounded behind eyes, postgenal process present, laterally indistinct, ventroposteriorly evident. Antenna with 39 flagellomeres; propodeum with anterior transverse carina indented centrally, thus not forming a smooth arc from side to side; area spiracularis enclosed in posterior and outer margins, not separated from area externa (lateral longitudinal carina anteriorly absent); area lateralis enclosed in outer (pleural carina present) and inner margins (lateral longitudinal carina present in posterior margin).

Description. Female. Fore wing 9.0 mm long. Head. In dorsal view with gena behind eyes rounded; posterior ocellus separated from eye by 1.1 × its own maximum diameter; postgenal process absent. Antenna with 39 flagellomeres.

Mesosoma. Mesoscutum smooth with isolated inconspicuous punctures; scutellum in profile weakly convex; hind wing with 1A not pigmented until the margin; propodeum about 2.1 × as long as broad; anterior transverse carina indented centrally, not forming a smooth arc from side to side; pleural carina present; posterior transverse carina, centrally absent; lateral longitudinal carina anteriorly absent; area spiracularis with a rectangular shape; area lateralis rectangular and enclosed, about 1.3 × as long as broad.

Map showing the localities where Grotea species have been collected in Colombia: yellow circles: Grotea santandereana sp. n., blue circle: Grotea villosissima Herrera-Flórez 2014 , red circle: Grotea cundinamarquesa sp. n., green circle: Grotea llanera sp. n.

Metasoma. Tergite I slender, slightly shorter than mesosoma from pronotal collar to posterior margin of pronotum; ovipositor, at rest, extending beyond the apex of metasoma by 2.6 × the length of the hind tibia.

Coloration. A black and yellow species. Head mostly black, frons centrally black, laterally yellow, interocellar area black; gena mostly yellow with hind part black; occiput black; face mostly yellow with black central spot; vertex, labrum and clypeus yellow; mandibles yellow, apex dark brown; labial and maxillary palp yellow; antennae: scape black, ventrally yellow; pedicel black; first 22 flagellomeres black, last 17 yellow. Mesosoma: pronotum anteriorly mostly yellow, centrally and posteriorly mostly black; propleuron yellow; mesosternum yellow; mesopleuron mostly black with longitudinal yellow stripes centrally and dorsally; mesepimeron yellow; metapleuron mostly black; mesoscutum black, with two longitudinal yellow stripes; scutellum anteriorly and centrally black, laterally and posteriorly yellow; postscutellum yellow; propodeum: area basalis, externa, superomedia and dentipara black; area spiracularis, lateralis, postero-externa, and petiolar yellow. Fore legs mostly yellow, except outer side of tibia with longitudinal stripe black; tarsi mostly yellow. Mid leg: coxa inner side yellow, central part with small black spot, outer side with longitudinal black stripe; trochanter and trochantellus black; femur yellow, outer and anterior side, with longitudinal black stripes; tibia black, inner side with yellow longitudinal stripe; tarsi black: Hind leg: coxa black, lateral and central part with logitudinal yellow stripes; trochanter and trochantellus black, with apical part of inner side yellow; femur black, with apical part of inner side yellow; tibia and tarsi dark brown. Wings hyaline (Fig. 13). Metasoma: tergites I–VII centrally black, laterally and posteriorly yellow; tergite VIII mostly black, laterally yellow; sternite I black, remaining sternites brown with black spots.

Remarks. Grotea cundinamarquesa sp. n. superficially resembles G. llanera sp. n. by having a black and yellow coloration but it differs from it by having a propodeum with anterior transverse carina centrally indented and antenna with 39 flagellomeres while G. llanera sp. n. has a propodeum with anterior transverse carina forming a smooth arc (Fig.1) and 40 flagellomeres.

Grotea cundinamarquesa sp. n. also superficially resembles G. cortesi ( Porter 1989) from Chile in coloration, however, the flagellum of this species is uniformly black to brownish, while in G. cundinamarquesa sp. n. the last 17 flagellomeres are yellow. Also the fore wing length is different: 6.0–7.0 mm in G. cortesi , 9.0 mm in Grotea cundinamarquesa sp. n.

Etymology. The name refers to the type locality: Cundinamarca Department of Colombia.
