Crassignatha Wunderlich 1995
No full textGenus Crassignatha Wunderlich, 1995 Crassignatha Wunderlich, 1995: 546. Type species Crassignatha haeneli Wunderlich, 1995. Family placement. Conflicting opinions have led to instability in the family placement of Crassignatha. Wunderlich (1995) described Crassignatha as part of the family Synaphridae (which he considered a subfamily of a broadly circumscribed Anapidae). Marusik and Lehtinen (2003) suggested it might belong to Symphytognathidae; Wunderlich (2004: 1081) suggested Anapidae (sensu stricto); Platnick (2008) has cataloged it under Mysmenidae. The systematics and circumscription of symphytognathoid spider families, especially Anapidae and Symphytognathidae, is in need of revision. Nevertheless, we predict that an affinity between Crassignatha and at least some Patu among the Symphytognathidae will be born out, supported in part by similarities in cheliceral armature and the male tibia II clasping spur. Diagnosis. Distinguished from other symphytognathid genera except Patu and Curimagua Forster & Platnick, 1977 by having the chelicerae fused only near the base (Fig. 78A); distinguished from Patu by the sculpturing of the carapace (Fig. 77 E-F; Wunderlich 1995: fig. 15); usually further distinguished from Patu by the abdominal scutum in the male wrapping around the posterior (Fig. 74A; scutum absent in C. haeneli, Wunderlich 2004); from Curimagua by having eyes in three diads (two triads in Curimagua; Forster and Platnick 1977) and one (entire or bifid) or two cheliceral teeth (Figs 78A, 91E; Curimagua is toothless; Forster and Platnick 1977). The poorly known genus Anapogonia Simon, 1905 was not considered for this diagnosis. Description. Tiny ecribellate araneoid spiders. Total length 0.6-1.3. Six eyes in three doublets (Fig. 82F, 91C). Carapace with fields of tubercles and pores (Figs 77E, F, 91A-D). Head region and clypeus raised in male, clypeus with two vertical clusters of sulci (Fig. 82F). Sternum truncate posteriorly. Chelicerae fused near base, fang furrow absent, usually with a single anterior tooth bearing a small mesal apex (Fig. 78A) except in C. longtou, which has two subequal teeth (Fig. 91E). Labrum weakly sclerotized, without spur (Fig. 78 B-C). Female palp absent. Metatarsus-tarsus joint without synaphrid-like distal constriction (see Lopardo et al. 2007). Tarsal organ near proximal margin, round, on slightly raised base (Fig. 78D). Tibiae with two dorsal rows of trichobothria, metatarsi I and II (plus III in C. longtou) with trichobothrium. Male tibia II with field of 2-4 thick setae on ventral distal part. Abdominal setae long and sparse. Male abdomen usually with scutum laterally and posteriorly; female without scutum, although a sclerotized ring around spinnerets may be present (Fig. 80B). Spinnerets with ventral orientation. Adult male retains flagelliform aggregate triplet (Fig. 85F). Colulus absent (Fig. 85E). Epiandrous gland spigots absent (Fig. 78E). Male palp: Palpal tibia without trichobothria (Fig. 77C). Cymbium with dorsal tooth near distal margin (Fig. 77B). Tegulum large and bulbous. Plate-like median apophysis on prolateral part of bulb. Membranous apophysis arises from near anterior part of median apophysis (Fig. 82C). Embolus usually thick, rigid, more or less spiral, rarely long and flexible. Vulva: Epigynum present, usually a short rounded scape (Fig. 79), rarely a transverse bulge (Fig. 91F). Two round spermathecae separated by about their diameter. Copulatory ducts follow a path to near apex of scape (Fig. 76B); fertilization ducts inconspicuous. Species. Wunderlich (1995) established Crassignatha to accommodate C. haeneli based on a single male specimen from Malaysia. Seven new species are added to the genus: C. pianma, C. yinzhi, C. quanqu, C. yamu, C. ertou, C. gudu, and C. longtou.Published as part of Miller, Jeremy, Griswold, Charles & Yin, Chang, 2009, The symphytognathoid spiders of the Gaoligongshan, Yunnan, China (Araneae: Araneoidea): Systematics and diversity of micro-orbweavers, pp. 9-195 in ZooKeys 11 (11) on pages 68-69, DOI: 10.3897/zookeys.11.160, http://zenodo.org/record/57645
Spatiator martensi Wunderlich, 2006, n. sp.
No full textSpatiator martensi n. sp. Figs 1 –3, 5 Type material: Male holotype in Baltic amber, its origin is most probably the region of Kaliningrad (Königsberg), F 1688 /BB/AR/ CJW, SMF. Derivatio nominis: This species is dedicated to Prof. Jochen Martens, University of Mainz, who discovered numerous arachnids which were new to science; I had the pleasure to describe some of the spiders which were collected by J. Martens in Nepal. J. Martens and the present author have been in close and best contact for 35 years. Diagnosis ( ♂; Ψ unknown ): Close to Spatiator praeceps, but embolus in S. martensi n. sp. not that slender, forming a large triangle, and tips of embolus and conductor separated (Fig. 3). Description ( ♂ ): Measurements (in mm): Body length 4.3, prosomal length 2.1, opisthosoma: Length 1.9, width 1.3; leg I: Femur 1.3, patella 1.7, tibia 1.15, metatarsus 0.85, tarsus 0.8, tibia IV 1.5, its diameter 0.14. Color: Body and legs dark brown, opisthosoma yellow brown. Prosoma (Figs 1, 5) ca. 1.7 times longer than wide, cephalic part distinctly raised, thoracic fissure long, setae indistinct, mostly short, cuticula fairly rugose. 8 eyes in two rows, anterior median eyes distinctly largest, posterior row distinctly procurved. Basal cheliceral articles large, retrolaterally with a large field of stridulatory files, fangs short, peg teeth hidden. Gnathocoxae converging above the labium which is long and slender. Sternum finely rugose, prolongated between the coxae IV. Petiolus is long and apparently symmetrically bipartite. Legs fairly long and slender, order IV/I/II/III, bristles absent, setae short and indistinct Tibia and metatarsus I slightly bent, bearing some prodorsal to prolateral spatulate setae, tarsi I–II bear a weak ventral pseudoscopula, metatarsus III bears a dense field of long ventral preening setae in the distal half. Opisthosoma (Figs 1, 5) oval, 1.45 times longer than wide, dorsally covered with short setae and hardened (apparently leathery) along its whole length. Epigaster sclerotized, lung covers hairless, small; epiandrous gland spigots absent. Spinnerets short and partly hidden. Pedipalpus (Figs 2–3) fairly small, with stout articles, tibia with a short prodorsal bristle and at least one dorsal trichobothrium. Cymbium wide, enclosing the bulbus, with few strong prodorsal setae besides long normal setae, bulbus long, tegulum large, embolus in a retroventral position, conductor distinctly separate from the embolus and in a more prolateral position and bent distally to the embolus, sperm duct easily recognizable. Female: unknown. Relationships: Only a single congeneric species has been described previously: Spatiator praeceps. The holotype of S. praeceps is a female. I described a male which I regarded as conspecific with the holotype, see Wunderlich (2004: 768, 807, fig. 56) (in this figure I probably mistook the embolus for the conductor). This male is probably conspecific with the female holotype of S. praeceps but — according to the distinctly different structures of their bulbi — it is not conspecific with S. martensi n. sp. No somatic differences are known to exist between these three specimens. This case reflects a fundamental problem in the taxonomy of numerous congeneric — fossil species: (a) the generotype is known from one sex only (or is juvenile), (b) no somatic differences between different species are known and (c) it is not likely to find both sexes in the same piece of amber: How do deal with different congeneric species of the other sex? Occasionally — for practical reasons — fossil specimens from the other sex were described as different species (in contrast to extant species), e.g. by Petrunkevitch (1942). So it would be consequent to designate a new name for Spatiator praeceps sensu Wunderlich (2004) but this is not a matter of this paper. I found no somatic differences between the present holotype and the material of praeceps sensu Wunderlich (2004) but the bulbus structures are clearly different (and in my opinion surely not caused by circumstances of the preservation): embolus and conductor are in close contact in the male of S. praeceps (Fig. 4) in contrast to S. martensi n. sp. (Fig. 3). Distribution: Early Tertiary (Eocene) Baltic amber forest. Preservation: The spider is situated at the corner of a yellow piece of amber which has a size of 3.1 x 2.0 x 0.9 mm. Legs and pedipalpi are completely and well preserved, some parts are darkened apparently by heating, the ventral side is weakly covered with a white emulsion, the opisthosoma has a low longitudinal depression dorsally (probably the result of a blow), a bubble is situated close to the left cymbium, but distinctly separated from the cymbial cuticula. Syninclusions: Four Formicidae, workers (body length 1.3, 2.4, 2.4 and 4.3 mm), remains of the abdomen of an ant (two parts, 1.4 mm long) 2 mm right of the spider in the same layer of the amber, an adult Acari (body length 1 mm), few tiny to small larvae of Acari (body length up to 0.5 mm), numerous stellate hairs of plants, numerous small bubbles and bubbleshaped particles which are dried out as well as particles of detritus. Notes: (a) Myrmecophagy: Remains of an ant — two parts of an abdomen — near the spider's body may be remains of the spider's prey, but this presumption is quite tentative: Most relatives of the Spatiatoridae, e. g. Archaeidae and Palpimanidae, are araneophages. The complete ants in the same piece of amber are apparently not injured. (b) Myrmecomorphy: The silvery glancing cuticle in most congeneric specimens (S. praeceps) which are preserved in pieces of amber which were not heated, the slender body and legs as well as the raised cephalic part — which give the illusion of a tripartite body of the spider — may be hints that these spiders were only weakly antshaped. We do not know the behavior of the fossil spiders, and a saddleshaped inclination of the opisthosoma is absent. Therefore I am not sure about the actual antmimicry of these fossil spiders. The largest ant which is embedded together with the spider has the same body size as the spider and may have been a model of a probable Batesian mimicry. The small ants may have been the model of conspecific juveniles.Published as part of Wunderlich, Jörg, 2006, Spatiator martensi n. sp., a second species of the extinct spider family Spatiatoridae in Eocene Baltic amber (Araneae), pp. 313-318 in Zootaxa 1325 on pages 314-317, DOI: 10.5281/zenodo.17402

No full textMaculoncus parvipalpus Wunderlich, 1995 (Figures 1a‒d) Maculoncus parvipalpus Wunderlich, 1995: 647, f. 12‒19 (♂♀) Material. ISRAEL: Haifa, 31.xii.2010 (YM) – 1♀ (ZMMU) Comments. This species was previously only known from Greece (Peloponnese Peninsula and Naxos Island) (Wunderlich, 1995). It can be easily recognised by the pattern on carapace (Figs 1 a-b) and abdomen (Fig1 1a, c), long hairs covering the abdomen (Fig. 1a) and the shape of the copulatory organs. It was recorded in Israel for the first time. Haifa is the south-easternmost record of M. parvipalpis.Published as part of Zonstein, Sergei, Marusik, Yuri & Omelko, Mikhail, 2015, A survey of spider taxa new to Israel (Arachnida: Araneae), pp. 372-385 in Zoology in the Middle East 61 (4) on page 374, DOI: 10.1080/09397140.2015.1095525, http://zenodo.org/record/80796

On applying the set covering model to reseeding
No full textThe Functional BIST approach is a rather new BIST technique based on exploiting embedded system functionality to generate deterministic test patterns during BIST. The approach takes advantages of two well-known testing techniques, the arithmetic BIST approach and the reseeding method. The main contribution of the present paper consists in formulating the problem of an optimal reseeding computation as an instance of the set covering problem. The proposed approach guarantees high flexibility, is applicable to different functional modules, and, in general, provides a more efficient test set encoding then previous techniques. In addition, the approach shorts the computation time and allows to better exploiting the tradeoff between area overhead and global test length as well as to deal with larger circuits
