Hendelia kinetrolicros ( Caloren & Marshall, 1998)

( Figs 6 , 33–36 )

Clusiodes kinetrolicros Caloren & Marshall 1998: 295 . Hendelia kinetrolicros . Lonsdale & Marshall 2007: 147.

Diagnosis. Body length 4.7–5.3mm. Bristles black and vibrissa narrow. Hind fronto-orbital approximately as long as anterior fronto-orbital. Base colour of head and thorax light reddish-brown with gena, occiput and antenna (excluding apical margin) yellower, and frons, back of head, pleuron, scutellum and medial stripes on scutum brown. Male with mid coxa and mid and hind femora rusty-brown (femora sometimes with yellow medial band), and fore tibia and tarsi dark brown. Vein R2+3 curved anteriorly and wing with apex, medial patch, and distal portion of first radial cell dark. Male with three-segmented genal process; apical segment flat, subtriangular, tomentose and slightly iridescent. Surstylus smooth and with bristles long and thin. Apex of ejaculatory apodeme exceptionally wide. Pregonite strongly arched. Spermatheca globose with apex narrowed and basal half with minute transverse wrinkles.

Distribution. Costa Rica, Mexico (Chiapas, Veracruz).

Comments. In Hendelia kinetrolicros , the distal edge of the terminal segment of the male genal process is brilliantly silvery tomentose and the entire process has a bluish iridescence (not evident on the holotype, but distinct in the other males examined and apparent on living flies; see Fig 6 ). Hendelia kinetrolicros is darker than most congeners, being almost entirely brown to rusty-coloured.

The specimen listed above from Monteverde was observed for about 15 minutes as it perched on a small diameter twig projecting over a stream at about eye level, periodically walking back and forth. No females or other individuals were seen, so there was no opportunity to see if the genal processes (“cheek antlers”) would be deployed as expected in male-male agonistic interactions.
