O macho de C. cambara Levi, 1986 é considerado como pertencente à C. itaimba Levi, 1986. A fêmea de Chrysometa aramba Levi, 1986 e o novo macho atribuído à C. cambara Levi, 1986 são descritos pela primeira vez. Registros atualizados de C. aramba, C. cambara, C. itaimba, C. boraceia Levi, 1986 e C. ludibunda (Keyserling, 1893) são apresentados.

PALAVRAS-CHAVE: Araneoidea; Metainae; distribuição geográfica; Sistemática

Tetragnathidae Menge, 1866 is a cosmopolitan spider family belonging to the Araneoidea (Álvarez-Padilla et al., 2009). Nowadays species of the family are distributed in 49 genera and 994 species and the highest diversity of the family is found in tropical and subtropical regions (World Spider Catalog, 2017). Tetragnathidae differs from other araneoids by the following characters: simple male pedipalp, conductor and embolus coiling together, characteristic spinneret spigot anatomy and particular web building behaviors (Álvarez-Padilla & Hormiga, 2011).

Chrysometa was proposed by Simon (1894) to include the species described as Tetragnatha tenuipes Keyserling, 1864. Specimens of the genus differ from other tetragnathids by presenting femurs IV lacking trichobothria combined to abdomens with silver or white spots; males presents a cymbial apophysis and a distinctive terminal apophysis; females present a flat epigyne usually without projections and fertilization ducts often more sclerotized than connecting ducts (Levi, 1986; Nogueira et al., 2011). Apart from smaller size, males of the genus usually have longer legs than females (Levi, 1986).

Levi (1986) published the only taxonomic review of the group illustrating 127 of the 139 species of Chrysometa, many of them known only by one of the sexes (World Spider Catalog, 2017). However, the distributional data of Chrysometa is still largely unknown and, since many species of the genera are described based on single specimens, it can be expected that several species are yet to be discovered (Álvarez-Padilla, 2007; Levi, 1986; Nogueira et al., 2011). Based on the examination of a large amount of males and females recently collected together in a ecological survey at Paraná State, in southern Brazil, and the examination of material of the arachnological collection of the Museu de Ciências Naturais da Fundação Zoobotânica do Rio Grande do Sul (MCN), we conclude that the male described by Levi (1986) as belonging C. cambara Levi, 1986 actually belongs to C. itaimba Levi, 1986. Herein we also describe the female of Chrysometa aramba Levi, 1986 and the new male assigned to C. cambara. Geographical distribution data based on new MCN records are presented for the above cited species and also for C. boraceia Levi, 1986 and C. ludibunda (Keyserling, 1893), including recent collection data and reviewed records from Rio Grande do Sul State presented by Buckup et al. (2010).


All specimens examined are deposited at the Arachnological collection of Museu de Ciências Naturais da Fundação Zoobotânica do Rio Grande do Sul, Porto Alegre, Brazil (MCN; R. Ott). Other institutions referred: American Museum of Natural History, New York, USA (AMNH), Museum of Comparative Zoology, Harvard University, Cambridge, USA (MCZ), Museu de Zoologia, Universidade de São Paulo, São Paulo, Brazil (MZSP).

The left male palps were detached for examination; epigynes were also removed from the abdomen and examined immersed in clove oil. Incident light images were taken through a stereomicroscope with attached camera and processed with Helicon Focus multi-range program. Transmitted light images of cleared female epigynes were taken with a compound microscope using a digital camera and also processed with Helicon Focus (Kozub et al., 2012). Drawings were made using printed images as models and compound microscope and stereomicroscope as details confirmation tools.

Nomenclature is based on Levi (1986). The asterisk symbol “*” after locality means “New record”. All measures are in millimeters.

Chrysometa arambaLevi, 1986:144, figs. 231-233. Male holotype from Cambará do Sul, Rio Grande do Sul, Brazil, 9.I.1976, A. A. Lise leg., deposited in MCN 3348 (examined).

Other material examined. BRAZIL, Rio Grande do Sul: Canela*, ♀, 28.IX.2000, A. L. H. Silva leg. (MCN 33360); São Francisco de Paula, , 25.XI.1998, A. L. H. Silva leg. (MCN 30960); ♀, 1.II.1999, A. L. H. Silva leg. (MCN 30883); Candelaria*, ♀, 5.II.2001, R. Ott leg. (MCN 33619).

Diagnosis. This species is very close to C. boqueteLevi, 1986 by having a discrete conical apophysis on the dorso-proximal region of the cymbium with no ectobasal or ectomedian process in males (Figs 4, 5; see also Levi, 1986:138, 139, figs 190, 191) and by the presence of a large knob-like epigynal septum and reniform shaped spermatheca with wrapped spermatic ducts in females (Figs 9-14; see also Levi, 1986:138, 139, figs 185-188). Males of C. aramba (Figs 1-5) can be also distinguished by the palp bearing a flattened, oval shaped paracymbial apophysis, with bulged prolateral border and smooth lower end (Figs 4, 5), which is corniculate in C. boquete. Females can be further distinguished by the almost as wide as long trapezoidal shaped median knob-like septum (Figs 9, 10), which is wider than long in C. boquete.

Rodrigues leg. (MCN 47407); ♂, 13.IX.2011, P. E. S. Rodrigues leg. (MCN 48095).

Diagnosis. Females are close to C. nigrovittata (Keyserling, 1893) by the general shape of epigyne (Figs 36-37); they can be distinguished by the shape of the septum, with rounded anterior borders (see Levi, 1986:181, figs. 519-526). Males are close to C. ramon Levi, 1986 and C. columbicola Levi, 1986 by the general shape of bulb and paracymbium (see Levi, 1986:193, figs 622-627); they can be distinguished from these species by the shape of the conical retrolateral portion of the paracymbium and also by the shape of the cymbial processes with a long and ventrally concave distal process and a conical proximal one (Figs 31, 32).

Description. See Levi, 1986:178, 181, figs. 519-522 for female and Levi, 1986:192, 193, figs 622, 623 for the male (paratype of C. cambara).

Remarks. Levi (1986) stated the possibility that male and female originally described for C. cambara does not belong together. The male designed by Levi as paratype was herein identified to belonging to Chrysometa itaimba Levi, 1986, the identification of males of this species is supported by the similarity in male and female sizes and on the coloration pattern between male and female specimens (Figs 28-30, 33-35) and also by the fact that in many samples males and females were collected together.

Variation. Total lenght: males, 3.59-5.20; females, 3.80-5.96. Note: Levi, 1986:192 states 3.80 total length for the male paratype originally described for C. cambara. This size matches the variation above registered for C. itaimba. All measured males and females of C. cambara presents a larger size range (respectively 5.46-6.55 and 6.24-7.45).

Distribution. South and Southeast of Brazil.

The presented data allowed increasing the distribution data of Chrysometa aramba, C. boraceia, C. itaimba, C. ludibunda and especially C. itaimba. However the correction of the assigned males of C. cambara, which were considered here to belong to C. itaimba, changes considerably the range of C. cambara presented by Buckup et al. (2010). This species, which was formerly also assigned to Pampa areas of Rio Grande do Sul state, is now known only from the north half of the state, in the Araucarias plateau. On the other hand, the range of C. ludibunda, originally described from Rio de Janeiro state, is increased to Paraná and Santa Catarina states, being recorded in Rio Grande do Sul only at the very northern border of state.
