( Figures 6–8 )

Material examined

Holotype (♀). “ Putaendo [ Chile] 28.XI. 82 M. Pino.” ( BMNH)

Female: whole insect, see Figure 6 ; fore wing length 7 mm. Antenna with 29 flagellomeres. Tergite I 1.35 times as long as apically wide, tergite II 0.65 times as wide as long. Body almost entirely finely coriaceous and with close, small, shallow punctures. Mandible basally coriacous and medially punctate, smooth on apical two thirds. Pronotum with longitudinal striation / crenulation over central, lateral area and posterior margin. Mesopleurum with speculum unsculptured, shiny. Propodeum with stronger coriacous sculpture than thorax, dorsal surface with transverse striations, short posterior face lacking striations. Coxae coriaceous, femora closely, finely punctate. Metasoma with sparse punctation, with tergites I–III coriaceous, then progressively less sculptured towards apex. Other characters as in generic description.

Colour: body basically black with copious white markings described as follows: head with broad, inner orbits up to top of head, outer orbits up to two thirds height of eye, as broad as mandible base at lower end, progressively narrowing; basal half of clypeus and two diverging lines from upper edge of clypeus to one third face height; large basal patch of mandible; pronotum with broad anterior stripe; mesopleurum with three white spots, on subtegular ridge, upper end of epicnemial carina and lower, posterior corner; mesoscutum with lateral, anterior stripes to just inside notauli; mesoscutum with central spot; scutellum with large central spot; postscutellum with small, central spot; tergite I with narrow, apical stripe over central two thirds, tergite VII with complete, broad, apical stripe, stripe increasing in size and extent over intervening tergites; sclerotized parts of sternites black, membranous areas creamy white, hypopygium largely brown / black with broad, apical rim. Thyridia brown. Legs with coxae black, large white marks on lateral surface of fore and mid coxae, longitudinal stripe on upper, lateral surface of hind coxa; trochanter of all legs dorsally black, fading to red laterally / ventrally; remainder of legs red, fading to dark brown / black on apical tarsomeres, with hind tarsus predominantly dark brown / black; inner faces of trochanters with narrow, apical, off-white streak and fore trochantellus predominantly cream-coloured.

Male: unknown.

Etymology

The specific name is taken from the Hawaiian leiomano, a fearsome-looking, sharktoothed club, and is to be treated as a noun in apposition.
