“…The male palp is slightly similar to that of T. caaguara Rodrigues & Ott 2005b, T. esmeraldas Dupérré & Tapia 2017, T. circuloargenteum Wunderlich 1976, and T. taiwanica Zhang, Zhu & Tso 2006 in lacking a conductor projection but distinguished by the presence of two parallel embolic apophyses. The female genitalia of the new species is slightly similar to that of T. chiripa Rodrigues & Ott 2005a and T. taiwanica in lacking sclerotized processes, and the edge of the genital plate posteriorly curved, distinguished by angular lateral corners of genital plate, with the genitalia longer than the width (distance between posterior edge of genital plate and anterior edge of spermathecae is longer than the width of genital plate) in the new species (Figs. 6E, F; 12I, J; Rodrigues & Ott 2005a;Zhang et al 2006).…”

“…Mysmenidae, Theridiosomatidae and Symphytognathidae generic rank identification were relatively easy thanks to contributions to the taxonomy of these families (Coddington 1986;Gertsch 1960Gertsch , 1971Lopardo & Hormiga 2015;Forster & Platnick 1977); however, their knowledge in Neotropical regions have presented slow progress where only species descriptions for specific areas are available (Brescovit et al 2004;Dupérré & Tapia 2017;Rheims & Brescovit 2003;Rodrigues & Ott 2005a, 2005b. For Theridiosomatidae, both Epilineutes Coddington, 1986 species and one Theridiosoma O. Pickard-Cambridge are probably new taxa.…”

Spider community inventories have relatively well-established standardized collecting protocols. Such protocols set rules for the orderly acquisition of samples to estimate community parameters and to establish comparisons between areas. These methods have been tested worldwide, providing useful data for inventory planning and optimal sampling allocation efforts. The taxonomic counterpart of biodiversity inventories has received considerably less attention. Species lists and their relative abundances are the only link between the community parameters resulting from a biotic inventory and the biology of the species that live there. However, this connection is lost or speculative at best for species only partially identified (e. g., to genus but not to species). This link is particularly important for diverse tropical regions were many taxa are undescribed or little known such as spiders. One approach to this problem has been the development of biodiversity inventory websites that document the morphology of the species with digital images organized as standard views. Their main contributions are the dissemination of phenotypic data for species difficult to identify or new with the assignment of species codes, allowing species comparisons between areas regardless of their taxonomic status. The present paper describes a protocol to produce these websites almost automatically. This protocol was successfully applied to 237 species from a tropical primary forest in Mexico. The time and infrastructure required for the documentation of these species are discussed. Taxonomic information in terms of identification challenges, possible new species, and potential nomenclatural issues is described. In addition, the conventional community parameters (e. g., inventory completeness, species richness estimations, sampling intensity) are also calculated and compared through time and between methods. An optimized version for sampling allocation effort per season is presented and compared with protocols optimized for other tropical forests.

ABSTRACT. Spiders of family Theridiosomatidae: a new species and new records for Brazil. Theridiosoma caaguara sp. nov. from Rio Grande do Sul state, Brazil, is described and illustrated. Baalzebub baubo Coddington, 1986 is recorded for the first time for Brazil and the known geographic distribution of Epilineutes globosus (O. P.-Cambridge, 1896), Naatlo splendida (Taczanowski, 1873) and Ogulnius obtectus O. P.-Cambridge, 1882 is extended. KEYWORDS.Araneae, Theridiosoma, Neotropical, taxonomy, distribution. A família Theridiosomatidae é composta por aranhas caracterizadas, principalmente, pelo esterno largamente truncado na região posterior e com glândulas em depressões localizadas na promargem, adjacentes ao lábio, clípeo elevado e longas tricobótrias tibiais (CODDINGTON, 1986). Constroem teias orbiculares complexas (ARCHER, 1953) e preferem locais escuros (CODDINGTON, 1986 Descrições e a terminologia do palpo seguem CODDINGTON (1986;1990). Todas as medidas são apresentadas em milímetros (mm).Theridiosoma caaguara sp. nov. Etimologia. O nome específico refere-se aos índios da tribo caaguara, primeiros habitantes na localidade-tipo. (Figs. 1-6) possui o palpo similar ao de T. gemmosum (L. Koch, 1877) (CODDINGTON, 1986, figs. 134-137, 146-149) pela presença de dentículos na margem do tégulo abaixo da base do condutor (Fig. 4), mas distingue-se pela forma do condutor alargada e mais distante do címbio, apófise média sobre o condutor (Fig. 4) terminando arredondada, com uma pequena dobra, apófise embólica esclerotinizada com região distal afilada (Figs. 4, 5), não projetada como em T. goodnightorum Archer, 1953(CODDINGTON, 1986 Carapaça amarelo-clara, área ocular castanho-escura. Quelíceras, lábio e enditos amarelo-claros. Esterno castanho-amarelado com bordas enegrecidas (Fig. 2). Pernas amarelo-claras, exceto coxas com bordas distais escuras e tarsos castanho-amarelados. Abdômen dorsalmente amarelo-claro, laterais e região posterior Diagnose. O macho de Theridiosoma caaguara
