Helconichia areolata n. sp.
(Figs 31, 40)
FEMALE DESCRIPTION.
Length: 3.0 to 3.2 mm.
Colour: Dull yellow and brown; brown as follows: antenna (scape and pedicel somewhat lighter),
ocellar triangle, hind tibia and tarsus, most of terga 3-7; wings lightly infuscate.
Structural features: antenna with 28 to 29 flagellomeres; setae of eyes short, about equal to diameter
of ommatidium; ratio of vein 2Rs:3Rs of fore wing 1.65 (Fig. 31); hind wing with 3 hamuli (Fig. 40);
propodeum without posterior median longitudinal carina; metasomal median tergite 1 ratio of length from base
of medial carina / apical width, 0.72; median tergite 1 with longitudinal carinae widely separated medially,
distance between carinae about equal to distance from carinae to lateral margin of tergite.
REMARKS. Male unknown.
ETYMOLOGY. Areolata is Latin meaning with small spaces and refers to the relatively well areolated
propodeum of this species.

Helconichia trichiops n. sp.
FEMALE DESCRIPTION.
Length: 2.7 to 3.3 mm.
Colour: Dull yellow and brown; brown as follows: antenna (scape and pedicel somewhat lighter),
ocellar triangle, mesoscutum laterally and anteriorly (mesoscutum may be entirely dull yellow), mesopleuron,
apex of hind tibia, hind tarsus, metasomal terga 2 to 8 light brown (reduced to terga 4 to 8 in some specimens);
wings lightly infuscate.
Structural features: antenna with 24 to 25 flagellomeres; setae of eyes long, at least 4 X diameter of
an ommatidium; ratio of vein 2Rs:3Rs of fore wing 1.2; hind wing with 3 hamuli; propodeum with posterior
median longitudinal carina; metasomal median tergite 1 ratio of length from base of medial carina / apical
width, 0.79; median tergite 1 with longitudinal carinae almost meeting medially, distance between carinae
much smaller than distance from carinae to lateral margin of tergite.
MALE DESCRIPTION. Essentially as in female.
ETYMOLOGY. Trichiops is Greek meaning `hairy eyes' and refers to the long setae on the eyes of this species.
