( Figs 114–116 )

Oxysarcodexia festiva Lopes & Tibana, 1987: 338 ; Costa Rica, Cartago, Turrialba. Holotype male in CAS (examined from photographs).

Diagnosis. [Based on the original description ( Lopes & Tibana 1987) and on photographs provided by Dr. Norman Penny (CAS).] Male. Length 9.0 mm. Postocular plate with golden pollinosity. Ocellar bristles about the size of the smaller frontal bristles. Thorax with golden pollinosity dorsally and on mesonotum. Two well-differentiated posterior and 3 smaller anterior post-sutural dorsocentrals. Apical scutellar bristles absent. Legs brown. Abdomen with yellowish gray pollinosity, T4 with median marginal bristles. ST5 with slender and elongate apical arms covered with pilosity apically. Cercus with pre-apical dorsal recurrent lobe and distinct setosity at the apex. Distiphallus curved forwards, with trichosity ventroapically. Vesica robust with setosity-like projections ventrally; distal lobes elongate, membranous and with a pair of spines.

Remarks. This species is easily distinguished from other Oxysarcodexia species by the peculiar cercus, characterized by long pile dorsoapically ( Lopes & Tibana 1987) ( Fig. 116 ). Female unknown.

Distribution. NEOTROPICAL. Costa Rica.

Biology. Unknown.

Type material examined. No specimens were examined directly, but photographs of the holotype were provided by courtesy of Dr. Norman Penny ( CAS) .
