Chileana penai Janšta & Křížková , sp. nov.

Figs 26–32

Material examined: Holotype female labeled CHILE, Pichinahuel, Cord. Nahuelbuta, Arauco, 23.–31.I.1959. L. Peña. Holotype deposited in CNC.

Etymology: The species is named in honor of L. E. Peña, collector of all the newly described species of Chileana; penai (Latinized, noun) = genitive singular, masculine.

Diagnosis and identification: Scrobes smooth and shiny. Antennae low on head, nearly reaching imaginary line drawn between ventral margins of eyes; scape nearly reaching anterior ocellus; pedicel and all funicle segments, including anellus elongate. Frenum finely alutaceous. Propodeum with one complete median carina diverging posteriorly; sides of propodeum, hind coxa dorsally and gaster basolaterally with patches of dense white long hairs. Fore wing with speculum developed and basal cell entirely covered with setae. Hind femur only angulate rather than with distinct tooth in apical quarter; hind tibial spurs long, 0.65× as long as basitarsus, slightly curved and inserted slightly before apex of hind tibia. Ovipositor 0.8× as long as the body.

Description: FEMALE. Holotype. Body length excluding ovipositor 3.15 mm; length of ovipositor 2.5 mm. Head including scape, outer surfaces of coxae, fore femur, lateral panels of pronotum, tegulae, prepectus and mesepisternum with blue-green reflections. Part of vertex, mesepimeron and metapleuron with coppery-green tint. Rest of body very dark bronze-green, at most with occasional blue-green tint ( Fig. 26 ). Gaster mostly brown with some blue-green or coppery reflections dorsally and laterally. Pedicel, flagellum, inner surfaces of coxae and femora, outer surface of mid and hind femora, tibiae, tarsal segments and ovipositor brown. Wings hyaline, wing venation and all setae dark brown.

Head. 1.21× as broad as high; 2× as broad as long; 1.22× as broad as mesonotum at its widest part in dorsal view; HTE:LTE 1.47; msp long, HTE:msp 1.83. Temples relatively long, 0.4× LTE. Head alutaceous except scrobes smooth and shiny, and with thin, short, pale setae. Clypeus with anterior margin straight, ventral part of clypeus smooth ( Figs 27-29 ). Mouth 1.5× msp; malar sulcus well developed. Antenna with scape 5.33× as long as broad at its widest part, nearly reaching ventral margin of anterior ocellus; toruli inserted on line connecting ventral margins of eyes; relative measurements of segments = 48:19:7:16:15:14:14:14:14:14:27 ( Fig. 30 ), pedicel 2.71×, anellus 1.4×, F1 2.29×, F2 1.88×, F3 1.75×, F4 1.75×, F5 1.75×, F6 1.75×, F7 1.56× and clava 3.38× as long as broad; F1–F5 with two rows of MPS. POL 1.8× OOL, OOL 1.43× OD.

Mesosoma. Mesosoma 1.92× as long as broad. Pronotum in dorsal view 1.5× as broad as long, mesoscutum 1.13× as broad as long. Pronotum, mesonotum and scutellum except for frenal area coarsely alutaceous, and with numerous thin, short, erect brown setae ( Fig. 31 ). Scutellum 1.31× as broad as long; frenal area nearly smooth but delimited by alutaceous sculpture, and 0.33× as long as entire scutellum. Propodeum with one complete median carina diverging posteriorly into two branches; area between spiracles and median carina almost smooth with only a few shallow foveae anteriorly ( Fig. 32 ); sides of propodeum with numerous long, erect, white setae. Upper and lower mesepimeron nearly completely smooth and shiny; transepimeral sulcus nearly complete, linear, and delimiting upper and lower mesepimeron. Metapleuron alutaceous, almost bare, with only a few setae distally. Hind leg with coxa relatively long, 2.67× as long as broad and 0.68× as long as femur; dorsal surface of coxa with numerous rows of erect dense white setae; femur 4.27× as long as broad with single very short tooth in distal quarter; tibia 6.71× as long as broad; spurs long and curved, longer spur 1.88× as long as shorter one and 0.65× as long as basitarsus; basitarsus long, 0.49× as long as tibia. Fore wing 3.29× as long as wide, transparent, with dense brown setae; speculum developed; basal cell nearly completely covered with setae dorsally; marginal vein 1.71× as long as postmarginal vein and 4.83× as long as stigmal vein; stigmal vein 2× as long as broad at its broadest part; stigmal uncus very long, longer than breadth of stigma and reaching mid-length of stigmal vein; venation dark brown.

Metasoma. About the same length as mesosoma; in lateral view oval; in dorsal view 0.72× as wide as mesosoma. Petiole short, dorsally transverse. Gaster smooth and shiny dorsally or at most very slightly alutaceous, the sculpture more conspicuous laterally; Gt1 medially slightly emarginate, rest of tergites with straight margins; Gt1 with patch of long dense white setae basolaterally and Gt3–5 with few brown setae laterally. Ovipositor 2.38× as long as metasoma, ovipositor index 3.3.

MALE. Unknown.

Biology. Unknown.
