Zoobank: CDF6A279-5C92-4A02-8557-39EC9395DA57

Diagnosis — Small damaeid mites with thick layer of columnar and amorphous cerotegument. Prodorsum with raised interbothridial region (prodorsal protuberance), with or without tubercles of enantiophysis D ; enantiophyses B, L and apophysis P absent. Prodorsal setae medium sized, smooth, broadened, bent up to claw-like ex (). Bothridial seta short, setiform, heavily covered by cerotegument, distally attenuated to slightly flagellate. Parastigmatic tubercles uneven, Sa narrow, long, spiniform and Sp smaller, shorter, spiniform or almost reduced. Notogaster elongated, oval to ovoid in dorsal view, in lateral view conical-pyramidal, with highest point shifted posteriad (roughly at the level of setae lp). Spina adnata absent;

all notogastral setae in form of strong, smooth erect spines inserted more-less radially on distinct tubercles or even apophyses, short, mostly distinctly shorter than the distance to next more posterior seta. Ventral side without ridges and apophyses, tubercles E2 and V absent or very weakly developed. Discidium present. Legs moniliform, with tibial solenidia II-III coupled with seta d, seta d on tibia IV absent, tibial solenidion therefore free, but relatively short (about as long as or shorter than length of tibia), setiform. Trochanters III and IV with increased numbers of setae (trochanteral formula 1-1-4-3); femora I-II with nine setae (femoral formulas 9-9-9-9 or 9-9-7-7); genual setation: 4-4-4-4, tibial setation: 4-5-5-4, tarsal setation: 20-17-17-14.

Type species: Coronabelba unicornis n. sp.

Other included species — Coronabelba platynotus ( Grandjean, 1954) n. comb. (= Metabelba (Pateribelba) platynotus ).

Etymology — The prefix “ Corona -” is derived from the Latin feminine noun corona = crown, wreath. Notogastral setation inserted on tubercles and apophyses resemble a crown.
