Arphthicarus baloghi sp. n.

( Figs 8–12 )

Description – Measurements of holotype: prodorsum: length 262, width 192, height 86; sensillus 23, setae: in 25, le 18, ro 30; notogaster: length 485, width 364, height 338; setae: c 1 86, h 1 88, ps 1 76; genitoaggenital plate 137×94; anoadanal plate 164×83.

Colour brown. Surface of body covered with very strong sculpture.

Prodorsum without lateral carinae. Sigillar fields not visible. Sensilli very short with short stalk and rounded, smooth head. Setae fine, spiniform, rough; ro> in> le. Exobothridial setae vestigial.

Notogaster with 15 pairs of short (c 1 <c 1 - d 1), rigid setae, covered with small setae in distal half, only setae ps 4 spiniform, rough. Setae c 1–3 remote from anterior margin, c 2 more than setae c 1 and c 3. Vestigial setae and lyrifissures not visible because strong sculpture.

Ventral region. Setae h of mentum shorter than distance between them. Genitoaggenital plates with 9 pairs of setae with formula: 5(4+1): 4. Anoadanal plates each with 5 short setae anal setae longer than adanal setae. Adanal setae situated near the paraxial margin.

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

Comparison and diagnosis. The new species is distinguishable from congeners by the very short, globose sensilli, spiniform setae ps 4, different in shape than other setae and adanal setae situated near paraxial margin of adanal plates.

Holotype and 2 paratypes (in DATE): Cuba, Province Habana, Arroyo Bermejo , semideciduous forest, north-slope, litter sample, 16 XI 1981, leg. J. Rusek (from dr. J. STARÝ collection).
