Hartzell leg. Description . Body size up to 1.6 mm. Body shape slender, typical Desoria (Fig. 115F). Head shape normal. Abd. 5–6 almost completely fused, with a weak incision between the tergites and a distinct break in setal cover. Colour completely black, including extremities. Head without white spots between eye-fields. Freshly collected specimens with a greenish lustre. Unlike most species even small juveniles as dark as the adults. Ocelli 8+8, rather small. PAO oval, about 1.5 as long as diameter of nearest ocellus. Three setae associated with PAO (Fig. 48).

Ant. 3 organ, with a few additional sensilla (Fig. 46). Ant. 4 with bifurcate pin seta and a small apically expanded peg in the subapical organ. Labrum with 4/554 normal setae, apical edge with 4 sharp ridges and a composite ventral ciliation. Frontoclypeal field with 10–15 setae, two setae between antennal base and upper corner of labrum. Maxillary palp bifurcate, 4 sublobal setae. Labial palp complete, guard e 7 present; terminal seta on the papillae as long as guards. Hypostomal papilla with subequal H and h1/h2.
