NM L 40475 (Figs 4 C, F); outer surface of operculum. NM L 40719 (Fig. 4 D); external mould of venter with distinct muscle scars. NM L 40474 (Figs 4 G, H and I); internal mould of conch. All specimens come from the Buchava locality. Type horizon and locality. Middle Cambrian, Buchava Formation, Skryje Member, Paradoxides (Eccaparadoxides) pussilus Biozone; Barrandian area, Skryje–Tý&rcaron;ovice Basin, Buchava locality, Czech Republic (N 49 ° 56 '33.0", E 13 ° 44 ' 41.8 "). Material. In addition to the holotype, 25 mostly fragmented opercula and 15 conchs. Etymology. After the name of hunchback Quasimodo. Diagnosis. The same as for the genus. Description. Conch orthocone; dorsal side slightly vaulted in lateral view. Cross-section of conch subtriangular with a high keel. W/h index = 1.3, angle of divergence ranging between 15 and 20 degrees. Amblygonal aperture; semicircular ligula provided with one transversally elongated apertural muscle scar. Other scars are positioned on lateral edges, being situated slightly behind the aperture. These scars being elliptical in outline and very distinct on mould. Apical septa probably not developed. Surface sculpture of conch consisting of very fine, almost indistinct growth-lines. Platyclaviculate operculum flat and robust clavicles divided by longitudinal diaphragms in hollow channels. In crosssection triangular cardinal processes opened and broadly diverging. Their anterior and posterior ends almost parallel; their axes lying in one line. Very thick-walled cardinal area sagitally elongated into rounded processes. Several radial channels developed between the outer and inner surfaces of cardinal shield. These channels most probably made the cardinal shield lighter. Distinct paired adductor muscle scars arched and deflected. Sculpture of external opercular surface consists of growth-lines. Several thicker riblets developed near summit of operculum. Dimensions. Maximum length of adult specimen was 25 mm. Occurrence. The type species Q. quasimodo sp. nov. is known only from the middle Cambrian of the Skryje– Tý&rcaron;ovice Basin at the localities Biskoupky, Buchava and Hradišt&ecaron;.Published as part of Valent, Martin, Fatka, Oldřich, Szabad, Michal, Micka, Václav & Marek, Ladislav, 2015, Skryjelites auritus gen. et sp. nov. and Quasimolites quasimodo gen. et sp. nov. — two new middle Cambrian hyolithids (?

    Lamparia pratensis Shear & Marek 2022, n. sp.

    Lamparia pratensis Shear & Marek, n. sp. Figs 26–29, 66–68 Types: Male holotype from Grassy Flat Campground, Rt. 199, 5 mi by road E of Gasquet, Del Norte Co., California, 41.8564°N, - 123.8890°W, 700’ asl, collected 25 March 1976 by A. K. Johnson. The specimen is mounted on SEM stub WS35-10, deposited in FMNH. Etymology: The species epithet is a Latin adjective, meaning “of the meadow,” and refers to Grassy Flats, the type locality. Diagnosis: Very similar to the L. millicoma n. sp., but distinct in the form of the ninth legs, which lack the expanded coxosternum, the median coxosternal knob, and the curved coxosternal process. Instead, there is a smaller triangular coxosternal process (compare Figs 68 and 71). Description: Male holotype. Length, 5.0 mm, width 0.45 mm. Two black ommatidia on each side of head. Sixth crests well extended as broad paranota (Figs 26, 27). Telson lobes nearly completely suppressed (Fig. 29, tel). Metazonital setae not seen, absent or concealed by heavy cerotegument. Color after long preservation medium brown. Flasks of third coxae short, when extended posteriorly reaching only to anterior margin of fifth coxae. Other characters as described for genus. Gonopods (Figs 66, 67) moderately large. Coxae with 3 setae, bulbous, with acute angle distally (Fig. 66, cx). Anterior angiocoxites narrow, erect, with slightly expanded, curved tip, posterior and anterior surface finely fimbriate from base to about half length of coxite (Figs 66, 67, aac). Posterior angiocoxite much reduced; flagellocoxite not sheathed. Flagellocoxite (Figs 66, 67, fc) single, thin, short. Colpocoxite bulbous, shifted anteriomesally, set with a few triangular, fine cuticular teeth (Fig. 67, cc). Ninth legs (Fig. 68) with coxosternum. Coxosternal processes flattened, long, bluntly triangular (Fig. 68, cp), arising near midline. Telopodites (Fig. 68, cp) free, rounded, with projecting posterior lobe. Tenth coxae not much swollen, gland openings anteriodorsal. Females not collected. Distribution: Known only from the type locality.Published as part of Shear, William A. & Marek, Paul E., 2022, The millipede family Striariidae Bollman, 1893. VI.

    Plaramia Shear & Marek 2022, new genus

    No full text
    Plaramia Shear & Marek, new genus Type species: Plaramia arcata Shear & Marek , n. sp. Etymology: The genus name is an arbitrary combination of letters, an anagram of the related genus name Amplaria forming a Latin neologism to be treated as feminine in gender. Diagnosis: The flagellocoxites are long, thin and largely concealed in this genus and the ninth leg telopodites are free. Thus we place the genus in Striariinae. Three of the striariine genera described in this paper have their metazonital crests all roughly subequal and not paranota-like. The two species of Plaramia, n. gen., differ from those of Maraplia, n. gen., in that the gonopod anterior angiocoxites are erect and sinuously curved, rather than reflexed anteriorly and either short or if long, curved in an arc. In Ralampia, n. gen., the gonopods are quite compact, and the colpocoxites have long, erect, branched, stiff fimbriae distally. Description: Small striariines, about 3–4 mm long (Fig. 46). Thirty postcephalic rings, including telson. Two ommatidia on each side of head (Fig. 45, om). Head (Fig. 37) densely setose, with small tubercles. Labral hook lacking. Mandibular stipes with serrate margin, acute triangular process. Collum with crests limited to posterior region, studded with small tubercles. Metazonital crests 1–5 subequal (Fig. 41), crest 6 slightly elevated as paranota (though variably so; Fig. 46); metazonital setae long, with brush-like tips. Telson with lobes very shallowly demarcated or nearly indiscernable, sulci shallow. Legpair 1 (Fig. 37, L 1) larger than legpairs 2 or 3, femora and tibiae with long, needle-like setae, tarsus with comb. Legpair 2 with short telopodites, vas deferens openings in coxae facing mesally, coxae notched so that when appressed, a single pore is formed. Legpair 3 with relatively short flasks (Figs 38, 48, cf), reaching fifth coxae when extended posteriorly, heavily set with raised cuticular scales, few contorted setae. Legpairs 4–7 crassate, legpair 7 lacking coxal lobes. Gonopod sternum large, broader than long (Fig 43, s). Coxa with 4–6 setae, coxal process absent. Anterior angiocoxites long, not deflexed, sinuously curved or with hooked termination (Figs 42, 43, 72, 73). Posterior angiocoxites small, inconsipicuous, forming short sheath for flagellocoxites. Flagellocoxites single, long, thin, concealed by angiocoxites. Colpocoxites large, sac-like, seemingly well sclerotized, with fine longitudinal ridges but lacking fimbriae. Ninth legs (Figs 44, 78) with coxosternite and free telopodites. Coxosternite with two processes from coxal part, sternal part sometimes expanded, with central knob. Telopodite large, variable, with pebbled sculpture and setae, with deep notch to accommodate gonopods. Telopodite locks into deep notch in ventrolateral margin of pleurotergite 7. Tenth legs with coxal pores, coxae slightly enlarged.
