Figs 9–16 EtYmologY:The prefix para (near) is Latin and refers to the similarity of the new species to Hoplophthiracarus tryssos Niedbała, 2004 . Measurements ( holotype ). Prodorsum: length 217, width 151, height 101, setae: ss 20, in 71, le 28, ro 30, ex 25; notogaster: length 424, width 273, height 252, notogastral setae: c 1 56, c 1 / c 1 - d 1 =0.6, h 1 and ps 1 25; genitoaggenital plate 96×71, anoadanal plate 162×78. Description: Integument. Colour white-Yellow. Surface of bodY covered with fine punctation. Prodorsum ( Figs 9, 10 ). Distinct lateral carinae and sigillar fields. Sensilli short with thin pedicel and swollen head, rounded in lateral aspect and fusiform in dorsal aspect. Prodorsal setae short, fine, attenuate, interlamellar setae distinctlY longer than lamellar and rostral setae. Notogaster ( Fig. 14 ). Fifteen pairs of short, fine and attenuate setae. Setae c 2 more remote from anterior border than setae c 1 and c 3 . Vestigial setae f 1 situated anteriorly of h 1 , setae f 2 situated anteriorly above h 3 . Two pairs of lYrifissures ia and im present. Ventral region ( Figs 11–13 ). Setae h of mentum ( Fig. 13 ) as long as distance between them.Arrangement of genital setae: 4+2:3. Anoadanal plates with rather long, fine setae, similar in length except short ad 3 setae. Legs ( Figs 15, 16 ). Chaetome of legs of “incomplete type ”, femora of legs I with three setae, setae d remote from distal end of segment. Holotype : MADAGASCAR , Ranomafana National Park , 14.iv.2011 , 21°15'46.1"S 47°25'13.1"E , 983 m , sifting sample of forest leaf litter, Winkler apparatus extraction, leg. L.S. Rahanitriniaina and R . Raveloson , MAG-021 ( DATE ). Remarks: The new species is distinguishable from congeners by the presence of smooth, attenuate setae on its body. It is similar to the Brazilian species Hoplophthiracarus tryssos Niedbała, 2004 in size of bodY, length of lateral carinae on the prodorsum, and size and length of notogastral setae, but is distinguishable by the differences in length of the interlamellar and lamellar setae, longer setae on the anoadanal plates, and especially by the unusual position of vestigial setae f 2 and the different arrangement of genital setae 4+2:3 (three setae in progenital position), versus 4:5 (five setae in progenital position in H. tryssos ) ( Niedbała 2004 ).
