Austrophthiracarus baloghi sp. n.

( Figs 1–7 )

Description – Measurements of holotype: prodorsum: length 369, width 268, height 141, sensillus 88, setae: in 210, le 132, ro 63, ex 20; notogaster: length 727, width 505, height 454, setae: c 1 139, h 1 114, ps 1 139; genitoaggenital plate 177x141, anoadanal plate 303×177.

Species with neotrichy of notogastral and adanal setae. Colour light brown. Surface of body punctated.

Prodorsum with distinct sigillar fields. Posterior furrows and lateral carinae absent. Sensilli long, narrow, rigid, without head, covered with small spines in distal half. Interlamellar and lamellar setae long, erect, rigid, similar to notogastral setae, rostral setae spiniform, rough; in> le> ro> ex.

Notogaster with 20 pairs of rather short (c 1 <c 1 -d 1), rigid setae, covered with small spines in distal half. Additional setae in rows h and ps. Setae c 1 and c 3 near anterior margin, setae c 2 far from margin. Vestigial setae f 1 situated posteriorly of ps 1 setae. Twopairs of lyrifissures (ia and im) present.

Ventral region. Setae h of mentum considerably longer than distance between them.

Formula of genital setae: 9(4+5): 0. Anoadanal plates with 6 pairs of rough setae, 2 anal and 4 adanal setae, 2 posterior adanal setae longer than anal, two anterior adanal setae the shortest.

Legs. Chaetome of “complete type ”; setae d on femora I remote from distal end of article.

Comparison. The new species is similar to A. andinus ( Balogh, 1984) but interlamellar setae are longer and rostral setae are not so long and do not exceed the end of rostrum.
