description: Sternoppia paramirabilis sp. nov.
(Figs 21 –32)
Diagnosis. Body size 365–415 × 215–249. Rostrum rounded. Interlamellar setae straight and longer than sensilli. Sensilli with weakly swollen head, having two or three long ramifying branches on dorsal side and one short simple cilium on ventral side; head and stalk with small barbs. Ten pairs of short notogastral setae present. Setae c longer than other notogastral setae. Setae la inserted anterior to lm. Epimere I smooth or striate.
Description. Measurements. Body length 415 (holotype), 365–415 (mean 377; seven paratypes); body width 249 (holotype), 215–249 (mean 224; seven paratypes).
Integument (Figs 21 –23). Body color yellow-brownish. Surface of prodorsum, notogaster and anogenital region micropunctate (visible under high magnification, × 1000). Epimere I smooth (rarely striate), epimere III+IV with weakly developed polygonal ornamentation.
Prodorsum (Figs 21, 23–27). Rostrum rounded. Costulae well developed, parallel, widely placed from each other. Rostral (41–49), lamellar (53–61), interlamellar (98–106) and exobothridial (41–49) setae setiform, with short cilia. Interlamellar setae straight and longer than sensilli (86–98). Sensilli with weakly swollen head, having two to three long ramifying branches on dorsal side and one short simple cilium on ventral side. Head and stalk with small barbs.
Notogaster (Figs 21, 23, 29, 30). Ten pairs of notogastral setae short (lm clearly not reaching insertion of lp), setiform, smooth. Setae c (41–49) located anteriorly to lyrifissures ia and longer than other setae (28–32). Setae la inserted anterior to lm. Lyrifissures ia, im, ip, ih and ips distinct, thin, located typically for genus. Opisthonotal gland openings located posterior to lyrifissure im.
Gnathosoma. Subcapitulum longer than wide (82–86 × 53–57). Subcapitular setae setiform; h (24–28) and m (16–20) with short cilia, a shorter (12), smooth. Two pairs of adoral setae present, short (4), thin, smooth. Palps (61) with setation 0–2–1–3–9(+ω). Setae of femora with long cilia, setae of genua and tibia weakly barbed, setae of tarsi smooth. Solenidion long, thickened, blunt-ended, pressed to the palptarsus surface. Chelicerae (82) with two setiform, barbed setae; cha (24) longer than chb (16). Small thorn located posteriorly to cha. Trägårdh’s organ distinct.
Epimeral and lateral podosomal regions (Fig. 22). Epimeral setae 3a thickened, heavily ciliate; other setae setiform, with long or short cilia. Lengths of setae: 1a, 2a, 3a, 3b and 4b 24–36; 1c 73–82; other 49–57. Pedotecta I convex. Discidia triangular, blunt-ended.
Anogenital region (Figs 22, 31, 32). Six pairs of genital (g 1– g 4, 24–36; g 5, g 6, 20–24), one pair of aggenital (49– 57), two pairs of anal (20–24) and three pairs of adanal (32–36) setiform, ciliate. Lyrifissures iad located in paraanal position.
FIGURES 23–32. Sternoppia paramirabilis sp. nov., adult: 23—prodorsum, lateral view (gnathosoma, epimeral setae and legs not shown); 24—rostral seta; 25—lamellar seta; 26—interlamellar seta; 27—sensillus; 28—exobothridial seta; 29—notogastral seta c; 30—notogastral seta p 1; 31—genital plate, left; 32—anal plate, left. Scale bars (23) 100 μm, (24–30) 10 μm, (31, 32) 20 μm.
Legs. Similar with Sternoppia paraincisa sp. nov. Homology of setae and solenidia indicated in Table 1. Type deposition. Holotype: female (ZISP). Paratypes: five males (SZMN), one male and one female (PC). Etymology. The prefix para is Latin meaning “near” and refers to the similarity between the new species and the species Sternoppia mirabilis Balogh & Mahunka, 1968.
Remarks. Sternoppia paramirabilis sp. nov. is very similar to Sternoppia mirabilis Balogh & Mahunka, 1968 from Argentina, in having the combination of characters as follows: location of notogastral setae la and lm, lengths and number of notogastral setae, weakly dilated sensillar head, morphology of ventral plate. The former, however differs clearly from the latter by larger body size (365–415 × 215–249 versus 273–322 × 161–180 in S. mirabilis), presence of two or three sensillar branches (versus six or seven branches in S. mirabilis), and long (longer than sensilli) interlamellar setae (versus shorter in S. mirabilis).
