An Apparently New Haplothrips from Cuba

Abstract

Head longer than wide and longer than the prothorax; cheeks slightly convex, sides almost parallel; vertex rounded; surface smooth. Postocular bristles rather long but pale and inconspicuous, knobbed. A pair of smaller bristles in the middle of the dorsum, one at the inner angle of each eye and one behind each posterior ocellus. Eyes rather small, occupying about V3 the margin of the head and .6 the breadth; dark red; not pilose; facets small. Ocelli much larger than the facets of the eyes; red; bordered by heavy, dark red crescents; situated far forward, the posterior pair opposite the anterior '/3 of the eyes and close to their margins but not touching; anterior far forward, facing forward. Mouth cone reaching .5 or more across prosternum, labium well rounded. Antennae 8-segmented, 1.7 times as long as the head. Segment 1 broad at the base, truncated; 2 constricted near the base into a broad stalk, cut squarely off at the apex; 3 broadly vase-shaped with a rather narrow stalk at the base; 4 oval, broad, shortstalked; 5 and 6 barrel-shaped with a short broad stalk; 7 oblong with a broad base; 8 conical. All provided with many short dark bristles. Sense cones short, colorless and inconspicuous. Three and 4 yellowish brown, the others concolorous with the head and body. Prothorax a little shorter than the head, anterior margin slightly convex, posterior more so; sides diverging markedly posteriorly; coxae large and conspicuous. Surface free of sculpture. Long'but colorless knobbed bristles on each angle and on each coxa; two pair near the posterior border, a smaller pair near the middle and a larger laterad; a small pair near anterior margin. Pterothorax somewhat narrower than the prothorax (including coxae), sides slightly converging posteriorly; a few faint anastomozing lines near the anterior margin; 3 pairs of small bristles along the anterior margin and at least 6 pair along the sides. Legs rather long and slender. Fore femora considerably enlarged. Fore tarsi with a small curved tooth. Wings short, membrane reaching about to the fifth abdominal segment; fringing hairs very long, 5 interlocated ones. Abdomen rather long and narrow, quite so in some specimens; a pair of pale, rather large, knobbed bristles on the posterior angles of each tergite, and three pairs of heavy, curved, dark, sharp-pointed spines on the outer third of each dorsal surface of segments 2-5; the innermost of these, along (Continued on page 12) 7
