( Figures 4 , 5 )

Material examined

Holotype (♀). Honduras, Olancho: 11 km N Catacamas, 14 ◦ 56 ′ 56 ′′ N, 85 ◦ 54 ′ 53 ′′ W, 2010 ± 5 m, ridgetop cloud forest, Malaise , 9-12.V.2010, LLAMA #Ma-C-02-1-02 ( USNM).

Paratypes (3♀♀). One ♀ as in holotype ( USNM) . One ♀ as in holotype ( ZMUT) , one ♀ as in holotype ( BMNH) .

Female: whole insect, see Figure 4 ; mandibles, clypeus, face, scape and first flagellar segment, see Figure 5 ; fore wing length c. 3 mm. Antenna with 25 flagellomeres, first flagellomeres long. Tergite I c.1.9 times as long as apically wide, tergite II c.1 times as wide as long. Body almost entirely polished, shiny, with some long whitish hairs, mesopleurum and metapleurum more punctate (with hairs); propodeum with pleural, posterior transverse, lateromedian longitudinal, lateral longitudinal carinae behind posterior transverse carina strong: mesopleurum, metapleurum, hind coxa partly very finely coriaceous. Other characters as in generic description.

Colour: head shiny black, mandibles (except orange-brown teeth), ventral half of clypeus dull yellow ( Figure 5 ), palps whitish-yellow. Antennae dark brown, scape, underside of basal three or so flagellomeres yellowish-brown. Mesosoma more or less entirely shiny black, upper posterior corner of pronotum yellowish-brownish, tegula creamy white. Metasoma more or less entirely shiny black, tergite III with anterior yellowish-brown band, apical tergites fading to dark brown, sternites creamy whitish with some brown areas. Subgenital plate dark brown, posterior part yellowish-brown. Ovipositor yellowish-orange, ovipositor sheaths dark brown. Fore and mid legs dull yellow, final tarsomeres fading very slightly to light brown. Hind leg dull yellow, apical half of coxa dark brown, lateral-posterior part of femur with brown spot, tibia with two brown bands and tarsomeres brown. Wings hyaline, pterostigma, wing veins light brown.

Male: unknown.

Diagnosis

This species can easily be distinguished from T. peruensis sp. n. by, especially, the shiny black colouration of the head and more complete carination of the propodeum, with the pleural, posterior transverse, lateromedian longitudinal and lateral longitudinal carinae behind the posterior transverse carina all strong. The head of T. peruensis is yellowish-orange and only the pleural and posterior transverse carinae are strong. The two species are also geographically widely separated, with T. olearius only known from Central America ( Honduras) and T. peruensis only known from South America ( Peru).

Etymology

The specific name olearius is the Latin adjective meaning “oily”, referring to the overall shiny black appearance of this species.

Remarks

All the known specimens of Terrylee olearius were collected in a Malaise trap in Honduras.
