Niedbała, Wojciech & Starý, Josef, 2014, New species of Atropacarus (Hoplophorella), (Acari, Oribatida, Phthiracaridae) from the Afrotropical Region, Zootaxa 3774 (1) : -

Atropacarus (Hoplophorella) curtisetosus sp. nov.

( Figs. 1A–D )

Measurements of holotype. Prodorsum: length 167, width 121, height 51; sensillum 81, setae: in 18, le 10, ro 20; notogaster: length 296, width 195, height 177; setae: c 1 28, c 1/ c 1- d 1=0.4, h 1 28; p 1 20; genitoaggenital plate 83 x53; anoadanal plate 106 x78.

Description. Small species. Colour brown. Surface of body with cerotegument and covered with concavities.

Prodorsum ( Fig. 1A ) without lateral carinae. Posterior furrows present. Sigillar fields indistinct because cerotegument. Sensilli long, rod-like without head covered with cilia in distal half. Setae short, rod-like, stout, obtuse, and rough. Exobothridial setae vestigial.

Notogaster ( Fig. 1B ) with setae short (c 1<1/2 c 1- d 1), rigid, stout, obtuse, and rough, setae c 1 and c 3 remote from anterior margin, setae c 3 more so than c 1, setae c 2 considerably further. Only lyrifissures ip visible.

Ventral region ( Fig. 1C ). Genitoaggenital plates with nine pairs of setae with formula: 4+1: 4. Anoadanal plates with rough setae, setae ad 2 thickest and longest.

Legs ( Fig. 1D ) Formulae of setae and solenidia of “incomplete type ”. Setae d on femora I slightly remote from distal end of article, setae v’ absent.

Material examined. Holotype is deposited at DATE. Locus typicus: TAN-002, Tanzania, east slope of Southern Uluguru Mts., 18. XI. 2010, 07 °07'20" S, 37°38'37"E, altitude 2058m, mid-altitude afromountaine deciduous forest, litter sifting sample of leaf litter, leg. V. Grebennikov.

Etymology. The name curtus is Latin for “short” and alludes to the short prodorsal and notogastral setae.

Comparison. The new species is slightly similar to pantropical species A.(H.) stilifer ( Hammer, 1961) but is distinguishable by the shape of its sensilli without a head, its shorter notogastral setae, the location of ad 2 setae laterally to an 1 setae (versus near of setae an 2) and the absence of setae v” on femora I ( Hammer 1961, Niedbała 2001).
