14. Haplothrips phyllanthi , new species.

Female holotype: color dark brown including all femora and middle and hind tibiae; fore tibiae clear yellow with a slight dusky shading on outer margins; fore tarsi yellow, middle and hind tarsi light brown. Antenna! segments 1, 2, 7 and 8 brown, with 2 lighter at tip; 3 to 6 clear yellow with 6 slightly shaded in outer portion. Wings entirely clear. Prominent spines brown.

Head approximately as wide as long, broadly rounded; cheeks arched; eyes large, fully one third.length of head; mouthcone short, stumpy; third antenna! segment symmetrical, with only the outer sense cone present, hardly twice as long as wide; fourth segment broadly rounded, not quite twice as long as wide, with four sense cones; postocular spines about three fourths as long as eyes, with dilated tips. All spines present on prothorax and with dilated tips. Fore tarsus without tooth. Forewings with six double fringe hairs. Tube about one half as long as head and approximately twice longer than width at base. Hairs at end of tube longer than tube.

Total body length 1.57 mm.; head length 0.16 mm., width 0.15 mm. Prothorax length 0.117 mm., width including coxae 0.22 mm.; tube length 0.088 mm., width at base 0.048 mm. Antenna! segments length (width): II, 30 (24); III, 40 (23); IV, 43 (30); V, 40 (23.); VI, 33 (20); VII, 30; VIII, 20 microns. Spines at end of tube 100 microns.

Male allotype: similar to female in color and shape but fore tarsus with a short, broad-seated tooth.

Orote Peninsula, Aug. 2, on leaves of Phyllanthus rnarianus, holotype female, allotype male, and three para type males, Swezey (5480).

This species may be compared with aculeatus and kourdjumovi but these two have pointed body spines; cahirensis another species with antennal segments three to six yellow has the third segment asymmetrical and with two sense cones; cooperi would seem to be more nearly related but this species has broader wings, the third antennal segment is stouter and the thoracic spines are clear.
