THE SOUTHERNMOST RECORD OF SCHIZOMIDA IN SOUTH AMERICA, FIRST RECORDS OF SCHIZOMIDA FOR RIO DE JANEIRO AND OF STENOCHRUS CHAMBERLIN, 1922 FOR BRAZIL (ARACHNIDA, SCHIZOMIDA, HUBBARDIIDAE)

ANA LÚCIA M. TOURINHO & ADRIANO B. KURY

The order Schizomida has underwent in recent years substantial changes which caused the replacement of the old scheme of only a few genera by numerous generic names (REDDELL & COKENDOLPHER, 1995). The order is well distributed in the tropics worldwide, except for central-southern South America. There is a genus of the Hubbardiidae, Surazomus Reddell & Cokendolpher, 1995, which possesses many endemic species from northern South America, but the southernmost record of the order Schizomida in South America is from Amazonia. Sifting leaf litter specially looking for small arachnids during projects conducted in the Laboratory of Arachnology of the Museu Nacional-Rio de Janeiro, yielded no schizomids from central-southeastern Brazil. Surprisingly, sifting of litter from metropolitan Rio produced some females of the widespread species Stenochrus portoricensis Chamberlin, 1922, naturally occurring in Mexico and the Caribbean and introduced to many countries. Illustrations of the diagnostic features are given for specimens from the population of Rio. The Museu Nacional-Rio de Janeiro, Brazil is herein abbreviated as MNRJ.

Adriano B. Kury, Amazonas Chagas-Jr, Alessandro P.L. Giupponi and Abel Pérez González

Abstract: The Tocantins 2007 Expedition of the Project “Aracnídeos e Miriápodes da Mata Atlântica”(AMMA) produced many new records of arachnids and centipedes, with 61 morphotypes identified. Among the results are: OPILIONES: 30 morphotypes with six new records of families and one of subfamily from Tocantins state; discovery of two undescribed species of Roquettea Mello-Leitão, 1931; Saramacia alvarengai Kury, 1997 is newly considered a junior subjective synonym of Saramacia annulata (Mello-Leitão, 1931); Brotasus Roewer, 1928 is transferred to Escadabiidae; the gonyleptid genera Parapachyloides Roewer, 1913 and Schubartesia B. Soares, 1944 are transferred to Gonyleptinae; SCHIZOMIDA: one species, new record of the order from Tocantins and from the Cerrado biome; SCORPIONES: seven species, one of them new record from Tocantins and two morphotypes; Chilopoda: 19 morphotypes, SCUTIGEROMORPHA: a widespread species Sphendononema guildingii (Newport, 1845) and another morphotype; GEOPHILOMORPHA: one morphotype; SCOLOPENDROMORPHA: 16 morphotypes, seven of them new records.

Luis F. DE ARMAS y Jesús A. CRUZ LÓPEZ

ABSTRACT. A new species of the hubbardiid genus Stenochrus Chamberlin, 1922 is herein described from Cerro Tepezcuintle, San Miguel Soyaltepec, Tuxtepec, Oaxaca State, Mexico. Male resembles Stenochrus moisii (Rowland, 1973), a species that has been found 45 km south of Cerro Tepezcuintle, but female has spermathecae with lateral lobes longer and tube-like, not dome-shaped.
