description: Physotarsus eliethi Gauld, 1997 (Figs 27, 28)
Physotarsus eliethi Gauld, 1997: 198 –199. Holotype Ψ in AEIC. Physotarsus eliethi: Yu & Horstmann 1997: 455 (catalog).
Diagnosis. Lateral ocelli separated by 0.9–1.1X their widest diameter from each other and 1.6X their widest diameter from eye margin. Antenna with 24 flagellomeres. Pronotum completely glabrous. Mesoscutum shiny, impunctate. T1 about 2.3X as long as broad. Head dark yellowish, area around ocelli brownish. Mesosoma yellowish, metasomal terga 2–8 brownish. Hind tibia brown. Fore wing hyaline, apex brownish.
Physotarsus eliethi is readily distinguished from other smooth-bodied species with pale mesosomas by the exceptionally long, narrow first flagellomere (about 10X longer than wide).
Description. Female: Body (Fig. 27) 3.0 mm, fore wing 4.0 mm. Head (Fig. 28): Clypeal margin widely subtruncate laterally, with thick, rounded central lobe. Clypeus about 3.3X as wide as long, not divided medially by transverse depression. Anterior tentorial pits elongate, pointed laterad. Malar space 0.7X width of mandibular base. Face 1.6X as broad as long, rounded in profile, impunctate. Interantennal area flat, area immediately behind antennae weakly concave laterally turning convex before reaching ocelli. Anterior margin of torulus situated at about 0.6 of eye height. Interantennal distance greater than distance between lateral ocelli. Widest diameter of median ocellus slightly smaller than widest diameter of torulus. Lateral ocelli separated by 0.9–1.1X their widest diameter from each other and 1.6X their widest diameter from eye margin. Area between lateral ocelli slightly depressed, area immediately behind ocelli not sharply declivitous. Antenna with 24 flagellomeres, flagellomeres slender, first flagellomere about 10.0X longer than wide, 1.4X widest transverse diameter of eye, second flagellomere 0.7X length of first. Occipital carina present on ventral 0.5 of head. Mesosoma: Anterior margin of pronotum broadly truncate, laterally rounded and slightly upcurved. Lateral groove of pronotum weak, not extending ventrally past dorsal 0.3. Pronotum completely glabrous, impunctate. Mesoscutum shiny, impunctate. Epicnemial carina strongly angled towards anterior margin of mesopleuron. Mesopleuron very sparsely punctate ventrally. Propodeum with posterior vestige of pleural carina present; impunctate. Tarsal claws with stout setae basally. Fore wing marginal cell about 2.7X longer than wide; Cu1a about 0.4X length of 2cu-a. Metasoma: T1 about 2.3X as long as broad. Cerci indistinct.
Color. Yellowish to light orange, brownish markings present around ocelli and on T2-8. Antennae darkening apically. Hind femur dark orange to light brownish, rest of leg dark brown. Fore wing hyaline, apex brownish.
Male: Unknown.
Material Examined. Holotype: Ψ (AEIC, Type No. 3572): COSTA RICA, Cartago Prov., Braulio Carrillo National Park, 400 m, ii.1985 (H Goulet).
Remarks. Gauld (1997) described this species from a single specimen, and suggested that the specimen was probably collected in Limón Province rather than Cartago Province.
