Interbothridial tubercles small and not fused with anterior border of notogaster. Notogaster in axial part protruding anteriad and notogastral as well as interlamellar setae with about 3-5 bristles unilaterally.</p> <p>Measurements — Available specimens partly crushed, not allowing precise measurements. Body length of holotype about 300 µm, length of prodorsum about 100 µm, maximum notogaster width about 150 µm (actual values for damaged specimen).</p> <p>General characters — Original colour difficult to estimate, available fossil material pale, yellowish brown, partly covered with debris and dirt, making observation of finer structure difficult. Cuticle smooth as far as possible to observe, prodorsum laterally with granular microstructure.</p> <p>Prodorsum — Prodorsum relatively narrow, delicate. Rostrum with two incisions as usual for Dissorhina, central tooth broadly pentagonal, blunt anteriorly, bearing a pair of rostral setae, inserted close to each other. Lateral teeth of rostrum short, broad, with blunt, rounded tips. Pedotectum I weakly developed as triangular projection with rounded tip, only slightly projecting over prodorsal outline. Another blunt projection visible on the place of pedotectum II. Only proximal part of lamellar costulae developed (i.e. reaching from bothridium to prodorsal groove and not beyond), costulae finely developed, oblique, straight or only slightly bent. Bothridia relatively small, rounded, with no or only indistinct posterior lobe. Postbothridial tubercle separated from bothridia, developed as small round tubercle. Interbothridial tubercles rather small and fine, not fused with anterior border of notogaster, their mutual distance same or smaller than distance between them and bothridia. Longitudinal, laterally rounded and flat "ear-like" carina developed in lateral part of prodorsum, above insertion of leg II. Sensillus moderately long (65 – 70 µm), lanceiform, smooth, stalk about one half of the length or slightly longer, lanceiform head about 2,5 times broader than stalk. Prodorsal setae of different lengths and forms. Rostral setae rather fine, slightly bent or straight, smooth or with one bristle, about 27 µm long. Lamellar setae shortest, fine, straight, about 15 µm long. Interlamellar setae stronger, straight, slightly over 30 µm long with about 5-6 small bristles unilaterally, better visible in lateral view. Exobothridial setae not observed, their insertions nevertheless positioned on small tubercles. Another small tubercle may be present in close vicinity to them.</p> <p>Notogaster — Broadly oval in shape, with anterior border protruding anteriad, darker in transmitted light. Notogastral crista present, short, bearing short setae c1. Other notogastral setae longer, fine, attenuated towards the end, adhering to the surface. Setae h1 inserted closely to each other, distally divergent. Not all setae observable on available material, but at least setae la, lp, h2 and h3 with about 3-4 fine bristles unilaterally. Setae h1 and p1 smooth, without bristles. Approximate length of setae la 21 µm, lp 29 µm, h1 and h2 32 µm and p1 19 µm.</p> <p>Ventral characters — Infracapitulum as usual in Dissorhina, setae of infracapitulum and palps fine and smooth. Epimeral setation 3-1-3-3, epimeral setae straight, smooth, about 11 – 12 µm long, 1c and 3c and 4b-c being the longest. Trochanteral setae I and II very long, bent, with few short bristles. Epimeral area with several lighter maculae in central part. Discidium developed as small, blunt tubercle. Anogenital formula as usual (5g, 1ag, 2an, 3ad), setae smooth and narrow, mostly a bit longer than epimeral ones (g1 8 µm, g6 13 µm, ag 14 µm, an2 15 µm). Adanal setae longer, ad1 posterior, ad3 anterior to anal opening.</p> <p>Legs — One of the two individuals (holotype) was relatively well preserved, with almost all legs present, even if incomplete. Due to the risk of further destruction, only leg I was investigated. As far as possible to observe, leg setation formula corresponds to those of Dissorhina as usual i.e. setation of leg I: 1-5-2(1)-4(2)-20(2). Setae moderately long, at least some of them with several short bristles. Tarsal solenidia ω 1 and ω 2 of about same length, ω 1 blunt and bent towards the tarsal surface. Tibial solenidion ’ 1 setiform, longer than the length of tibia. Solenidion ’ 2 much shorter, blunt. Genual solenidion σ long, setiform, more than two times longer than the length of the segment.</p> <p>Material examined — Two individuals were available from the clastic sediments of Trhlovca cave in Karst, Slovenia. Individual from sample T5 from Pliocene red clay sediments (about 3,8 millions</p> <p>Miko L.</p> <p>of years old; see Moldovan et al., 2011 for further details) was much better preserved, and is designed as holotype. Individual (paratype) from sample T2 from Pliocene beige clay sediments (about 2,7 million years old) was damaged, in poor condition, without legs and practically without observable setation. Notogaster was largely damaged and dirty, not allowing more detailed study. Specific identity of the two individuals is judged on the basis of the same development of the rostrum, bothridia and lamellar costula, interbothridial and postbohridial tubercles and lateral part of prodorsum, and due to its occurrence in the same locality. Individuals are preserved in the collection of Emil Racovita Institute of Speleology in Cluj-Napoca, Romania.</p> <p>Derivatio nominis — The name " paleokrasica " is derived from "Kras", the name of the Slovenian geomorphological unit where is the type locality, Trhlovca cave. Prefix paleo- refers to the fossil character of the material.</p> <p>Remarks — Dissorhina paleokrasica n. sp. bears all important characters of the genus, and is close to the widely distributed and common species D. ornata. Our own studies showed that several characters of D. ornata may be rather variable (see also figures in Miko, 2006), so differences of the newly described fossil species needed to be carefully analysed against that variability.</p> <p>However, the newly described species can be distinguished from all other Dissorhina species by a combination of some specific characters, namely: (a) interbothridial tubercles are fine, weakly developed and not fused with anterior margin of notogaster (developed as separate tubercles); (b) anterior part of notogaster between setae c2 is arched and protruding anteriad; (c) central tooth of rostrum is broad, bluntly pentagonal or almost quadrangular, not trapezoid as in D. ornata or some other species; (d) notogastral setae except c2 and p1–p3 are quite long, and at least la, lp and h2 with small bristles.</p> </div>	https://treatment.plazi.org/id/03F887C4ED48826A8C6CD64D47F0F917	Public Domain	No known copyright restrictions apply.

Interbothridial sclerites near to each other, small, touching the anterior border of notogaster, but not fully fused with it. Insertions of interlamellar setae shifted backwards, near anterior margin of notogaster, laterally to interbothridial sclerites.</p> <p>Measurements — Damaged individual does not allow precise measurement, the values therefore represent actual values at damaged individual. Length of the body about 325 µm, length of the prodorsum about 105 µm. Maximum width of notogaster about 180 µm.</p> <p>General characters — Original colour difficult to judge, available material pale, yellowish brown, partly covered with debris and dirt, making observation of finer structure difficult. Cuticle smooth as far as possible to observe.</p> <p>Prodorsum — Triangular, shaped as usual in Dissorhina. Rostrum with elongated "naso"-like central tooth, protruding significantly beyond the anterior margin of rostral tectum. Lateral teeth reduced, broadly rounded. Pedotectum I present but weakly developed, protruding anteriad as a small rounded projection. Projection in the place of pedotectum II also present, but invisible in dorsal view. Costulae completely reduced, central part of prodorsum without visible cuticular structures, ridges or furrows. Postbothridial tubercles present, disctinct, and as usual for Dissorhina not fused with posterior end of bothridia. Interbothridial tubercles small, fine, positioned near to each other. These tubercles posteriorly not fused with but only touching anterior border of notogaster. Prodorsal setae missing on observed individual. Insertions of rostral setae positioned on the base of central tooth of rostrum. Positions of lamellar setae impossible to observe, insertions of interlamellar setae positioned close to the anterior border of notogaster, laterally to interbothridial sclerites. Insertions of exobothridial setae on small, but distinct tubercle, as usual in Dissorhina. Sensillus quite long (about 70 µm), with narrow elongated head of typical Dissorhina shape.</p> <p>Notogaster — Broadly ovate, anterior border arched, without projections. Only some insertions of setae observable, insertions of both c2 setae, left la, right lm, left h1 and h3 and both p3 not observed. Single seta la preserved on right side, rather short (18 µm), smooth, without visible bristles. Other characters of notogaster very hard to detect.</p> <p>Ventral characters — Infracapitulum and anal plates missing. Small but distinct pedotectum I and II visible. Epimeral area laterally with coarse granulation. Epimeral setation incomplete, even insertions not all visible. Nevertheless, epimeral setal formula can be reconstructed as 3-1-3-3. Only three epimeral setae preserved, smooth and fine, of different length (1a 11 µm, 4b 17 µm long). Anal opening visibly larger than genital opening, distance between them about as long as anal opening. Anal plates missing, and only incomplete set of setae and/or their insertions can be observed in anogenital region, anogenital formula except anal setae may be reconstructed as 5g, 1ag, 3ad. Adanal setae ad3 longest of all ventral setae (about 22 µm), aggenital setae only slightly shorter. Insertions of setae p1 and p2 also visible in ventral view, close to each other.</p> <p>Legs — Only trochanters of legs III and IV preserved, setation or insertions of setae invisible.</p> <p>Material examined — Single damaged individual (holotype) was available from the clastic sediments of Trhlovca cave in Karst, Slovenia, sample T2 from Pliocene beige clay sediments (about 2,7 million years old). Individual is preserved in the collection of Emil Racovita Institute of Speleology in Cluj-Napoca, Romania.</p> <p>Derivatio nominis — The specific name " nuda " reflects the absence of costular structures on prodorsum.</p> <p>Remarks — This species, due to the absence of prodorsal structures, was originally determined and recorded as Oppiella (Rhinoppia) sp., potentially a new undescribed species (see Moldovan et al., 2011). However, the position of the rostral setae, shape of sensillus, presence of isolated postbothridial tubercles not attached to bothridium and 5 genital setae place this species clearly within Dissorhina. The trend of the disappearance of prodorsal costulae and prodorsal furrow is common within Oppiellinae, and can be observed also in recent Dissorhina species, e.g. D. tricarinatoides (Dubinina, 1966). The new species can be easily distinguished from all known species of the genus by the unique shape of the interbothridial tubercles, combined with the absence of lamellar costulae and peculiar shape of the central tooth of the rostrum.</p> </div>	https://treatment.plazi.org/id/03F887C4ED4F82678C3DD4D64268FA4A	Public Domain	No known copyright restrictions apply.
