Protophthiracarus baloghi sp. n.

( Figs 13–18 )

Description – Measurements of holotype: prodorsum: length 291, width 192, height 126; sensillus 71, setae: in 56, le 18, ro 38; notogaster: length 550, width 404, height 364; setae: c 1 101, h 1 91, ps 1 96; genitoaggenital plate 131×96; anoadanal plate 187×101.

Colour light brown. Surface of body covered with deep concavities.

Prodorsum with weak median and distinct lateral carinae. Posterior furrows and sigillar fields distinct. Sensilli fairly long, with long narrow stalk and dilated, fusiform, smooth head rounded distally. Interlamellar setae rather short, procumbent, robust covered with small spines in distal half, similar to notogastral setae. Lamellar and rostral setae spiniform but lamellar covered with small spines and rostral setae rough; in> ro> le. Exobothridial setae vestigial.

Notogaster with 15 pairs of rigid, short (c 1 <c 1 - d 1), covered with small spines in distal half. Dorsal setae slightly longer than laterals. Setae c 1–3 remote from anterior margin, setae c 3 considerably further and setae c 1 less than setae c 2. Vestigial setae invisible. All four pairs of lyrifissures (ia, im, ip, ips) present.

Ventral region. Setae h of mentum shorter than distance between them. Genitoaggenital plates with 9 pairs of setae with formula: 6(4+2): 3. Anoadanal plates each with 5 rough setae, 2 anal and 3 adanal. Setae ad 2 the longest and thickest, setae ad 3 the smallest.

and femur of leg

Legs. Formulae of setae and solenidia of “complete type ”. Setae d on femora I remote from distal end of article.

Comparison and diagnosis. This species is distinguishable from congeners by the long sensilli, similar shape of notogastral setae, dorsal slightly longer than laterals, 4 pairs of lyrifissures, setae h of mentum shorter than distance between them.

Holotype and 7 paratypes (in DATE): Brazil, State S. Paulo, south of Săo Sebastiăo, rain forest at the base of the Serra do Mar , near Baia da Guaeca, 05.IX.1980, leg. R. Schuster (from prof. dr R. SCHUSTER collection).
