Diagnosis. Dendrozetes is unique in the Peloppiidae based on the following combination of character states. Adult: rostrum rounded; lamella parallel without well-developed cusp; exobothridial seta, if present, minute; dorsophragma and pleurophragma absent; pedotecta I and II well-developed; slender ridge present between bothridium and acetabulum II; sejugal apodeme transverse, without medial interruption; humerosejugal porose areas absent; epimeral border IV transverse, curving around genital plate, with minitectum present but incomplete adjacent to genital plate; coxisternal setation 3-1-3-3; notogaster with 8 pairs of setae, setae of c and d series and p 3 absent; seta h 1 large, prominent on posterior contour, pair diverging; p1 similarly large or minute according to species; other setae minute; 6 pairs of genital setae; 3 pairs of adanal setae of which ad 1 and ad 2 subequal in shape, but shorter than h 1, positioned on arched thickening posterior to anal plates; chelicera chelate-dentate; palp setal formula 0-1-2-3-9(1); acm associated with solenidion on palptarsus; axillary saccule of subcapitulum absent; legs tridactylous; porose areas present on all femora, tibiae and tarsi, and on trochanters III, IV. Immatures: larva and nymphs multideficient; larva with 7 pairs of setae, f 1, c 3, da , dm , dp and h 3 absent; nymphs with 10 pairs of setae, setae f 1, c 3, da , dm , dp and p 3 absent; in larva seta h 1 most terminal hysterosomal seta; in nymphs seta h 1 on terminal extension of hysterosoma; gastronotal setae baculiform, subequal in shape; hysterosoma tuberculate, strongly plicate when newly emerged, becoming weakly plicate; prodorsum smooth, porose; pulvillus on tarsi II, III and IV; paraproctal atrichosy in larva, proto- and deutonymph.
