Remarks

• Systematics: H. brasiliensis differs from all species included in the genus by presence of groups of microtubular ducts in one row on midline of the dorsum, not in two submedian rows.
• Structure: Female ovisac is cream colored. (Cockerell, 1900) Body elongate oval, 1.891 (1.891-2.020) mm long and 1.243 (1.243-1.295) wide. Antenna 7 segmented. there is one sensory pore on the 2nd segment. The 3rd segment is almost parallel sided. On apical segment, three falcate sensory setae. On the two preapical segments, falcate sensory setae are present. The segments of the antenna are covered with few hairlike setae. Frontal lobe present. eye visible, situated on venter. Venter: Labium apparently one-segmented. On undeveloped basal segment, two pair of setae present. stylet loop long, reachews the second soxae. Legs long. Posterior coxae, and femur, with small number of translucent pores. Trochanter with two pores on each side. Claw with denticle. Legs with few hairlike setae, and with one sensory pore on tarsus. Five-locular pores distributed in rare bands on all segments of abdomen and thorax. Venter with a small number of scattered, short hair-like setae. Cruciform pores present in a submarginal band. Microtubular duct absent. Macrotubular ducts of one size present in a small number on all segments. Dorsum: Dorsal setae spine-like, strong, short, found in two rows on most segments. on the margin 2-3 setae present. macrotubular ducts present in small number on all segments. Microtubular ducts with bifurcated end, forming two great groups containing more than 30 ducts on mid-dorsum on meso- and meta- segments of the thorax, anc scattered among dorsal setae elsewhere. disc pores absent. Anal ring situated between venter and dorsum, with eight hairlike setae. Anal lobes short, strong, as long as wide, with two spine-like setae along inner margin and one on outer margin. Anal lobes heavily sclerotized. Suranal setae hair-like. Cauda absent.
• Biology: This species was found in aggregations. (Cockerell, 1900).
