Austroearinus chrysokeras Sharkey n. sp.

Diagnosis

May be distinguished from all other known members of the genus with the following combination of characters; apical 4–6 flagellomeres yellow; propodeal areola wide and well developed, ovipositor slightly shorter than metasoma.

Description

Body length: 4.6 mm. Head: Antenna with 31 (30–32) flagellomeres. Mesosoma: Scutellar sulcus with one median longitudinal carina; median areola of metanotum well defined with sharp carinae laterally and posteriorly; margin between metepimeron and metepisternum with three well defined transverse carinae; foretibia lacking pegs; midtibia with 1 subapical peg, and lacking pegs at midlength; hind tibia with 3 apical pegs; second cubital cell of fore wing sessile and triangular; RS+M vein of fore wing well developed, almost complete but not tubular at midlength; fore wing length 4.6 mm; propodeum with well defined median areola; areola wider anteriorly; anterior transverse carinae of propodeum well defined. Metasoma: First median tergite with 2 distinct lateral longitudinal carinae extending three­fifths the length of the median tergite; median syntergite 2+3 length 0.93mm, width 0.77 mm.; ovipositor length subequal to metasoma length. Color: Mostly yellow except black as follows: antenna (except apical 4–6 flagellomeres, yellow), tarsal claws, apex of hind tibia, and entire hind tarsus; wings evenly infuscate.

Distribution Known only from Costa Rica.

Etymology chrysos and keras are Greek for gold and horn respectively. The combination is a reference to the yellow tips of the antennae.

Austroearinus melanopodes Sharkey n. sp.

Diagnosis

Female. May be distinguished from all other known members of the genus with the following combination of characters: Legs excluding coxae and fore and mid tarsi, partly or entirely melanic, at least the fore femora melanic. Vertex of head melanic at least in part, contrasting with lower face and gena which are yellow. Median tergite 1 of metasoma with two sharp carinae.

Description

Female. Body length: 4.6 mm. Head: Antenna with 32 flagellomeres. Mesosoma: Scutellar sulcus with one median longitudinal carina; median areola of metanotum well defined, with sharp carinae laterally and posteriorly, not deeply excavated; margin between metepimeron and metepisternum with three or four weak transverse carinae; foretibia lacking pegs; midtibia with 2 subapical pegs, and two pegs at midlength; hind tibia with 7 apical pegs; second cubital cell of fore wing sessile and triangular; RS+M vein of fore wing poorly developed, mostly absent; fore wing length 4.4 mm; propodeum with long narrow median areola, not distinctly wider anteriorly, anterior transverse carinae barely indicated laterad areola. Metasoma: First median tergite with 2 sharp lateral longitudinal carinae extending three­fifths length of median tergite; median syntergite 2+3 length 0.94mm, width 0.67 mm; ovipositor as long as body. Color: Mostly yellow except black as follows: antenna, parts of frons and face, all femora and tibiae, hind coxa apicolaterally, hind trochanter, hind tarsus; wings evenly infuscate.

Male. Unknown

Distribution Known only from Costa Rica. hind claw showing basal pectination. d) Lateral prothorax showing projection on propleuron.

2+3 showing strong transverse grooves. c) dorsal propodeum.

Etymology From the Greek words for black and feet, in reference to the predominately black legs that, in combination with the pale body, are distinguishing features of this species.
