description: Chaetonotus (Chaetonotus) polyspinosus Greuter, 1917 (Table 11)
Locality: Site 2, 3; session I, II, III.
Material: 33 specimens (27 adult and 5 juvenile), 30 specimens photographed.
Remarks: A very varied species with various morphological forms described by Kisielewski (1991). The specimens from the Poznań Palm House only partially (17 from all 30 measured specimens) fit into the ranges of the ones previously reported in the literature data. A part of the observed specimens have a different total number of longitudinal alternating rows (50–58 vs 38–47 given) and thus a different ratio of scales distribution (from 88.1% vs from 94%), and a and m pharynx formulas are lower than the reference (from 21.6% and 17.4% vs from 25% and 21%, respectively). The majority of specimens have longer neck and trunk scales (up to 7.7 Μm and up to 9.9 Μm vs up to 4 Μm and up to 7 Μm, respectively), and longer straight spines on the base of the furca (up to 23.3 Μm vs up to 18 Μm). However, it cannot be questioned that all of the recorded specimens belong to the species C.(C.) polyspinosus.

(Fig. 6)
Cyrtosia pusilla Loew, 1873: 206.
Material examined. 1 male, Turkmenistan, Ashkabad, Coll. Lichtwardt (ZMHB).
Diagnosis. This species is recognized from the congeners in Iran by the almost all black frons and all black scutellum. Other known species in Iran have either an almost all yellow frons or the scutellum with a yellow posterior margin. Here we provide a brief description to aid in identification.
Description. Head (Fig. 6 a) matte, longer than high; frons black except base of antennae yellow; face and occiput completely black; proboscis about equal to head height, black, matte. Thorax. Mesonotum (Fig. 6 b) completely black on disk, dusted; lateral margin from postpronotal lobe to postalar callus very narrowly yellow, interrupted at wing base by broad black stripe; pleura almost all black except yellow on the following: anterior margin and spot at posterior margin, upper margin of katepisternum, upper margin of anepimeron and katepimeron; scutellum black, dusted; halter stem and knob yellow.Legs. Coxae brown; femora brown except apical part narrowly yellow; tibiae yellowish brown; metatarsi yellowish, remainder brown. Wing. Hyaline (Fig. 6 c), Sc incomplete, ending at level about equal to origin of vein R2+3; vein R2+3 ending in wing margin equidistant from end of vein R1 and R4+5; cell dm open, without crossvein closing it apically; vein M1+2 one-half length of fork point to margin of wing; length of cell br 1.5 times that of cell bm, anal cell open widely at wing margin, width 1.5 times rm crossvein; fringe of hair on posterior margin of wing minute. Abdomen. Almost all black, except posterior margin of tergites narrowly yellow. Genitalia. Not dissected.
Remarks. This species is originally described based on a single male specimen from the region Kisilkum (Uzbekistan), a Turkish word meaning golden sandy land. Becker & Stein (1912) recorded C. pusilla Loew from Iran when recording specimens collected by Zarudny in 1898 in two provinces of southeast of Iran, Sistan- Baluchistan and Kerman.

Angarozonium amurense — Mikhaljova 2004: 45–48, 46: figs 22–27, 47: map 3.
Remarks. This species, originally described by Gerstfeldt (1859) from near the mouth of the Songari River, China as Platydesmus amurensis, then transferred first to Polyzonium (Mikhaljova 1979) and finally to Angarozonium, with the trans-Siberian Polyzonium cyathiferum Mikhaljova, 1981 as a junior subjective synonym (Shelley 1998). Slightly later the formal synonymy was confirmed by the re-examination of samples of what might be considered as near-topotypes (Mikhaljova 1998). This species appears to be widespread throughout the Asian part of Russia, including the northernmost known record of Diplopoda in Northern Hemisphere: Republic of Sakha, Yana River middle flow, ca 67˚40’N (Mikhaljova and Marusik 2004). At present the species is known from Siberia (Krasnoyarsk Province, Irkutsk Area, Chita Area, Buryatia, Republic of Sakha (=Yakutia)), Russian Far East (southern part of Khabarovsk Province, Jewish Autonomous Region, Kamchatka Peninsula, northern and central parts of Sakhalin Island), Northeast China (near the mouth of Songari River) and Mongolia (environs of UlaanBaatar).

Locality: Site 3; session I.
Material: 1 sample, 1 adult specimen, photographed.
Remarks: The Poznań Palm House specimen corresponds well with the ranges and appearance presented in the literature (Kisielewski 1997a, Balsamo 1983), with a few exceptions. The observed specimen have a body covered with rounded scales, not more rectangular ones like in the description. Moreover the a, m, p pharynx formulas are lower than in the reference (38.3%; 35.2%; 40.8% vs 43–46%; 44–46%; 51–57%, respectively). The biggest trunk scales of this specimen were significantly longer than the given literature value for the species (18.1 Μm vs 12 Μm). Also, the shortest neck spines and the shortest trunk spines were shorter than the given literature range (12.9 Μm and 11.7 Μm vs 25–33 Μm and 46–68 Μm, respectively). The lateral denticle on the neck spines and trunk spines is situated closer to the end of the spines than was previously reported (35.7–42.4% and 22.7–29.0% vs 57% and 33%, respectively).
Distribution: Previously recorded in Brazil (Kisielewski 1991), the Faroe Islands (De Smet et al. 1987), Germany (Brehm 1917), Great Britain (Martin 1990), Italy (e.g. Balsamo 1983), Japan (Sudzuki 1991), Korea (Lee & Chang 2000), New Zealand (Murray 1913), Poland (e.g. Kisielewska & Kisielewski 1986a, b, c), and Sweden (Kånneby et al. 2009), the United States (Emberton 1981).

description: Family Xiangxiellidae Shen in Chang et al., 1976
Remarks. Xiangxiellidae was defined as a subfamily in Chang et al. (1976) and attributed therein to the family Vertexiidae Kobayashi, 1954. Carapace valves of Vertexiidae have concavely recurved growth lines along the upper posterior margin below the dorsal margin, and sometimes a spine-like sculpture on its larval carapace valve (Kobayashi 1954; Astrop & Hegna 2015). These two characteristics are absent in Xiangxiellinae, which excludes this taxon from the family Vertexiidae sensu stricto. Instead, Xiangxiellidae became elevated to family rank by Kozur & Weems (2010), which is followed herein.

Remarks. This species, originally described in Diplomaragna (Shear 1990), has since been transferred to the restored Ancestreuma (Mikhaljova 2000). Hitherto the species is known from Russia (Siberia: Krasnoyarsk Province, Irkutsk area, Republic of Tyva) and Mongolia (Khubsugul Lake, River Ongolich). The record in Evenkia (Mikhaljova 1993) actually refers to Ancestreuma ryvkini (Shear, 1990). This conclusion was confirmed by the reexamination of a sample from the locality being kept at IBSS (1 male, Russia, Krasnoyarsk Province, Evenkia, 140 km upstream of Velmo River, 10.VIII.1990, leg. A.B. Ryvkin). The erroneous information about the record of this species in Evenkia (Mikhaljova 1993) was accepted in subsequent publications (Mikhaljova 2000; 2002; 2004).

description: Coryogalops Smith, 1958
Coryogalops Smith, 1958: 144 (type species: Coryogalops anomolus Smith, 1958 by original designation).
Diagnosis. Specimens were assigned to the genus Coryogalops based on the combination of the generic characters adopted by Kovačić et al. (2014) and updated in the present study: 1) head and predorsal area naked (except for C. monospilus with a few rows of predorsal scales); 2) longitudinal scales rows 26-46; 3) upper pectoral-fin rays at least partly free; 4) gill opening restricted, ending ventrally at lower base of pectoral fins; 5) united pelvic fins (fins separated in C. anomolus only); 6) cephalic sensory systems with separate anterior and posterior oculoscapular canals with pores σ, λ, κ, ω, α, β, ρ and ρ1, ρ2, respectively, and preopercular canal with pores γ, δ, ε; 7) suborbital papillae pattern transverse, with six or seven suborbital rows (except for Coryogalops bulejiensis (Hoda, 1983) that possesses five suborbital transverse rows (Goren, 1985)); 8) transverse suborbital row of sensory papillae 4 beginning close to eye, at level of upper half of papilla of row 5 (Miller, 1978; Goren, 1985; Randall, 1994; Kovačić et al., 2014, and the present description).
The monotypic Mediterranean genus Zebrus De Buen, 1930 fit the Coryogalops generic diagnosis given by Kovačić et al. (2014), but a single species Zebrus zebrus (Risso, 1826) easily differs from all Coryogalops species, including new species Coryogalops nanus sp. nov., by morphological characters (Miller, 1977). Anyway, the additional unique character (number 8 in Diagnosis) is added to Coryogalops diagnosis to distinguish the genus from Mediterranean genus Zebrus: transverse suborbital row of sensory papillae 4 beginning distant from eye in Z. zebrus, i.e. at the level of lower half of row 5 (Miller, 1977).

Synonym: Heterolepidoderma ocellatum var. sphagnophilum Kisielewski, 1981
Locality: Site 2; session III.
Material: 1 sample, 1 adult specimen, photographed.
Remarks: The specimen found in the Poznań Palm House corresponds well with the morphological features from the original description and redescription of this species (Kisielewski 1981; Kånneby et al. 2012). However, this specimen does not have a pair of ocular granules and shows differences in morphometry, such as a slightly greater body length (135 Μm vs 103–133 Μm), and shorter adhesive tubes (6.1 Μm vs 8–9 Μm). Additionally, the total number of longitudinal rows of scales is higher (24 scales vs 20–23 scales), therefore the ratio of scale distribution is different (92.3% vs 121–200%).
The presence or lack of ocellar granule is a useful feature (Kisielewski 1981), but this structure has been also reported to be either present or absent in different populations of the same species (e.g. Heterolepidoderma ocellatum (Mečnikow, 1865)) (Fregni et al. 1998; Schwank 1990). However, it follows the morphological data presented by Kisielewski (1981) and Kånneby et al. (2012) well, and is considered to be Heterolepidoderma acidophilum Kånneby et al., 2012.
Distribution: Previously recorded as Heterolepidoderma ocellatum var. sphagnophilum in Poland (Kisielewski 1981) and Russia (Tretjakova 1989), and in Sweden as Heterolepidoderma acidophilum by Kånneby et al. (2012).

description: Ichthydium sp. (Table 16)
Locality: Site 1, session II.
Material: 1 sample, 1 adult specimen, photographed.
Short description: This species has a long and slender body with parallel edges. The three–lobed head has a wide cephalion and large hypopleuria, but no epipleuria. The hypostomium is elliptical in shape. On the head there are two pairs of cephalic ciliary tufts. The mouth ring is situated ventrally. The pharynx has slight dilatations at the ends. The furca is massive and thick, with very short adhesive tubes. The branches of the furca are parallel and do not part outwards. On the furca base there is a posterior pair of dorsal sensory bristles. The posterior sensory bristles are anchored at small papillae, situated near the furca base. The body surface is not covered with cuticular structures visible in the light microscope. On the ventral side there are two longitudinal ciliary bands with very long cila. Ocellar granules absent.
Differential diagnosis: From all known Ichthydium species, this species resembles only the species Ichthydium rostrum Roszczak, 1969.
I. rostrum Roszczak, 1969 (80–100 Μm in length) is a smaller species with a similar body shape and comparable proportions. However, in Ichthydium sp. the body is more slender and the head outline is three–lobed, not single–lobed as in I. rostrum. Moreover, the pharynx is definitely shorter (18–24 Μm) than in the I. sp. (47.7 Μm), and posterior sensory bristles are absent. Both species have very short adhesive tubes when compared to the body length, but the adhesive tubes in I. rostrum are arranged outwards, unlike in the discussed species.

description: Ascetoaxinus gen. nov.
Type species. Ascetoaxinus quatsinoensis sp. nov., this paper.
Type locality. Quatsino Sound, off of Vancouver Island, British Columbia, Canada; 50°15.482’N, 128°26.400’W to 50°14.519’N, 128°26.567’W; 1086–1318m.
Species included. Ascetoaxinus quatsinoensis sp. nov.; Ascetoaxinus ovoidea (Dall, 1890).
Diagnosis. Medium sized shells. Equivalve. Inequilateral, prosogyrous beaks close to the anterior, outline obliquely oval. Anterior margin sloping steeply, almost straight; anterior area defined by a distinct keel, with a deeply impressed lunule encompassing the entire anterior area. Lunule edge scalloped by rounded projections. Posterior margin broadly rounded, indented by a single sinus; posterior sulcus large, deep, distinctly angulated; submarginal sulcus smaller, sharply defining escutcheon but no distinct marginal sinus. Weak angulation between umbo and posterior ventral margin resulting in flattened area adjacent to the posterior sulcus. Anterior adductor muscle scar greatly elongate. Hinge teeth lacking. Ligament partially sunken.
Gill anatomy of Dufour type 3 (Dufour 2005), filaments laminar, frontal surface broad, flat with marginal arrays of cilia. Lateral body pouches large, dense arborescent, dorsal extension of digestive gland prominent with external outgrowths.
Etymology. From the Greek asketos meaning curiously fashioned and pertaining to the unusual scalloped lunule and the Greek axinus meaning like an axe, but also pertaining to the thyasirid genus Axinus; gender feminine (Brown 1956).

Description. Carapace valves very large and elongated oval to oval in shape; dorsal margin slightly curved to curved, very short to long; larval carapace valve very small; position of the umbo submedial and marginal to supramarginal; anterior and posterior margins sharply curved to very sharply curved; points of maximum curvature of the anterior and posterior margins located median or slightly median-dorsal, and in the ventral margin median-anterior; the ventral margin is concavely indented in the median-posterior region of the carapace valve.
Size. Height (H) of the carapace valve between 3.2–4.9 mm; length (L) of the valve between 5.3–7.5 mm; 0.57<H/L<0.71; dorsal margin length (l) between 3.0–4.0 mm; 0.48<l/L<0.70; larval carapace valve height (h) between 0.2–0.9 mm; 0.06<h/H<0.2; often between 25–30 growth lines; all measurements based on 6 valves.
Occurrence. Punta Negra 2 site; uppermost part of Unit C, Aegean (Diez et al. 2010), lower Anisian (lower Middle Triassic).
Remarks. The genus name is written with a question mark, because neither its characteristic radial sculpture in the umbonal area nor microstructures (ornamentation) of the carapace valves could be clearly identified, possibly due to the imperfection of their preservation. Instead of a formal species name, open nomenclature is applied to this distinctive carapace valve morphology. This morphotype co-occurs with the above described Hornestheria? Morphotype 1 (Figures 8, 9). The latter mentioned morphotype reaches greater total carapace valve height values than Hornestheria? Morphotype 2 (Figures 10, 11). It also differs from Hornestheria? Morphotype 2 in having a more rounded shape.
Hornestheria? Morphotype 2 is of larger size than both H. sollingensis sensu stricto and Hornestheria sp. aff. H. sollingensis (Figures 2–6). The large carapace valves of Hornestheria? Morphotype 2 resemble similarly-sized clam shrimps, such as “ Isaura minuta albertii ” (see Reible 1962: plate 7-fig. 7) or E. albertii albertii (see Kozur et al. 1993: fig. 3), but differ from them in both its concavely recurved ventral margin and the morphology of the umbo.

Female broadly oval, male unknown. Head inclined forwards with frons broadly visible from above; basal two­fifths considerably reflexed, occluding anterior pronotal margin; in front subglobose, slightly broader than high, broadest across postgenae. Gena high, slightly less than half as high as eye. Antennophore located at apex of gena, far from ventral eye margin. Antennal segment II inflated, distinctly fusiform, about 2.5x as thick along the middle as segment I. Eyes distinctly separated mesally on frons, maximum width 2.4x as broad as minimum interocular space. Hemelytra with distinctly raised radial vein; embolium explanate at base, tapering towards apex; cuneus broader than long; membrane somewhat abbreviated, distinctly bi­areolate.
Type species: Namaquaropus niger sp. nov.
Comments
This new genus belongs in the tribe Myiommini, the commissure being very distinct and indeed slightly longer than the scutellum. Unlike the other two genera belonging to this tribe in Africa (i.e., Myiomma Puton and Slateropus Akingbohungbe), a short gula is present and, hence, the head in the new genus is inclined forwards. Unlike Myiomma but similar to Slateropus, the eyes are widely separated mesally in front of the ocelli, the maximum width of each being less than 3x minimum frontal interocular space. In contrast to the known females in these two other genera, the second antennal segment is prominently inflated and fusiform. Within the Myiommini, two New World genera, Brailovskiocoris Henry and Wetmorea Gibson, feature similarly inflated second antennal segments. However, the head in these genera is vertical and not inclined forwards; and the hemelytra are slightly to distinctly indented laterally rather than being broadly arcuate as in this new genus

Type-species. Schismatothele lineata Karsch 1879, by monotypy.
Species included. Schismatothele lineata Karsch 1879; Schismatothele inflata (Simon 1889) comb.nov.; Schismatothele modesta (Simon 1889) comb.nov.; Schismatothele benedettii Panzera, Perdomo & Pérez-Miles 2011.
Diagnosis. Males and females are distinguished from those of other theraphosid genera by the following features: male palpal tibia swollen bearing several short and thick spines; bulky, heavy sclerotized spermathecae. Schismatothele can also be recognized by the following features: palpal tibia with one row of spines; male palpal bulb short bearing a flat paraembolic apophysis, tegulum rounded at the base; male tibial apophysis with two branches, prolateral branch short, retrolateral long and curved; spermathecae receptacles heavily sclerotized with dorsal and ventral portions.
Description. Carapace oval, longer than wide; moderately pilose. Cephalic region slightly raised. Eye tubercle weakly raised, small. Eye group rectangular, anterior eye row procurved, posterior slightly recurved. Fovea deep, straight or procurved. Labium subquadrate, with 100–200 cuspules densely concentrated on the anterior half. Labiosternal junction moderately deep; labiosternal sigilla oval, distinct and located near junction. Sternum rounded, with conspicuous bulge near labiosternal junction, posterior sternal sigilla oval and away from margin. Male palpal tibia swollen, with thick spines (named ‘megaspine’ by Panzera et al. 2011) on retrolateral surface, disposed either in line or in groups. Male tibial apophysis comprising two branches. Male metatarsus I bends externally to retrolateral branch of tibial apophysis. Scopulae on tarsi III–IV divided by band of thick setae. Superior tarsal claws of males and females bare or with small teeth; inferior tarsal claws absent. Tarsi cracked on male and females. Cymbium longer than wide, bilobed. Palpal bulb with short embolus, large subtegulum and bearing keels. Spermathecae strongly sclerotized, comprising two receptacula (dorsal and ventral). Abdomen uniformly brown; abdominal markings present or absent.
