Biodiversidade em sete cavernas no Parque Estadual do Sumidouro (Lagoa Santa, MG).

O presente trabalho apresenta dados referentes à composição, riqueza, abundância, diversidade, dominância e similaridade em seis cavernas localizadas no Parque Estadual do Sumidouro, município de Lagoa Santa – MG. Foram observados 9051 indivíduos distribuídos em 175 morfoespécies pertencentes a pelo menos 87 famílias. A Gruta Túneis/Macumba apresentou a maior riqueza (78 espécies), seguida de Lapinha (75 espécies). A ordem que apresentou a maior riqueza foi Araneae (34 espécies) seguida de Diptera (32 espécies), contrastando com a ordem Neuroptera, que apresentou apenas uma espécie. Foram encontradas 2 espécies com características troglomórficas: Trichorhina sp. (Isopoda: Plathyartridae) ocorrendo na Gruta de Lapinha, Pacas e Helictites, e o ácaro Labidostomatidae (Acariforme), que foi encontrado somente na gruta da Lapinha. Este último requer atenção especial, dada sua distribuição restrita e população extremamente reduzida no interior da caverna, que possui visitação turística

Cladistic analysis and taxonomic review of Pseudonannolene Silvestri, 1895 (Spirostreptida, Cambalidea, Pseudonannolenidae)

Uma revisão taxonômica e análise cladística do gênero Pseudonannolene Silvestri, 1895 é apresentada. A análise compreende 53 terminais como grupo-interno e 10 como grupo-externo. 91 caracteres morfológicos foram codificados. Três sinapomorfias em comum suportam o monofiletismo de Pseudonannolene: presença de sutura longitudinal no promentum, conexão entre as bandas do pênis e ramo interno circundando telopodito; e duas transformações homoplásticas: collum densamente estriado e cerdas distribuídas até o ápice do processo pré-femoral do primeiro par de pernas dos machos. Pseudonannolene é recuperado como grupo-irmão de Epinannolene Brölemann, 1903 em Pseudonannoleninae. O clado é suportado por duas sinapomorfias: processo pré-femoral desenvolvido e tarso alongado do segundo par de pernas dos machos; e uma transformação homoplástica: telopodito estreito. Grupos mais inclusivos do gênero são detalhados e discutidos. Espécies de Pseudonannolene apresentam ampla distribuição ocupando a região Neotropical. Como revisto aqui, o gênero compreende 56 espécies, incluindo oito novas espécies. P. brevis Silvestri, 1902 e P. rugosetta Silvestri, 1897 são consideradas species inquirendae. Neótipo de P. alegrensis Silvestri, 1897 é aqui proposto e macho descrito pela primeira vez.

The analysis is based on a dataset including 53 species of the genus as ingroup and 10 species as outgroup. 91 morphological characters were scored for the analysis. Three common synapomorphies support the monophyly of Pseudonannolene: presence of longitudinal suture on promentum, connection between the bands of penis and internal branch surrounding telopodite; and two homoplastic transformation: collum densely striate and setae located at the apex of prefemoral process of the first legpair of males. Pseudonannolene is recovered as adelphotaxon of Epinannolene Brölemann, 1903, comprising the subfamily Pseudonannoleninae. This clade is supported by two synapomorphies: well-developed prefemoral process and elongated tarsus of the second legpair of males; and one homoplastic transformation: narrow telopodite. Some internal clades within the genus are detailed and discussed. As revised here, the genus comprises 56 species, including eight undescribed species. P. brevis Silvestri, 1902 and P. rugosetta Silvestri, 1897 are considered species inquirendae. Neotype of P. alegrensis Silvestri, 1897 is herein proposed and male described for the first time.

Pseudonannolene spelaea Iniesta & Ferreira, new species

Pseudonannolene spelaea Iniesta & Ferreira, new species (Fig. 2–6) Material examined. Holotype: 1 Male (fragmented) (ISLA 3797) from GEM – 1770 cave, Parauapebas/PA, Brazil, 21 /X/ 2010, Oliveira, M.P. coll. Paratypes: 1 Male (fragmented) (ISLA 3796) from GEM— 1744 cave, Parauapebas/PA, Brazil, 20 /IX/ 2010, Oliveira, M.P. coll.; 2 Female (ISLA 3794, ISLA 3795) from GEM— 1712 cave, Parauapebas/PA, Brazil, 30 /X/ 2010, Oliveira, M.P. coll. Etymology. Name given in apposition as a reference to the Latin word spelaea, meaning “cave”. Diagnosis. Distinct from all previously known species of the genus due to depigmented body and eyes (the eyes with few ocelli, between 10–15) and in the details of the gonopods. Live specimens can be seen in Figure 6. Description of Adults. Measurements: The measurements can be seen in Table 1. Colour: translucent white. Body Head Collum Head (Fig. 2): Head glabrous and depigmented. Three small labral teeth (not modified), a row of 15 labral setae and above a row of 6 supralabral setae. Mandibles depigmented, glabrous and with 2 external teeth above, 4 internal teeth and 6 rows on pectinate lamellae. Eyes depigmented with 10 to 15 ocelli, very difficult to see. Antennae depigmented and densely setose. Four terminal sensorial cones. First antennomere small, with setae exclusively positioned on the distal edge. Second and third antennomeres of similar sizes. Fourth antennomere a little longer than the fifth, and this possesses a wider, curved distal border. Sixth antennomere longer and wider than the fourth and fifth. Groups of basiconic sensilla measuring 15 µm, on the edge of the fifth and sixth antennomeres. Gnathochilarium (Fig. 3): The structure of the gnathochilarium is similar to that observed in other species of the genus Pseudonnanolene with few differences in relation to the disposition of the setae. Basal gula (Gu) with setae. Rounded mentum (Me) with small setae on the distal portion. Stipes (St) with basally and distally rounded lateral borders. Promentum (Pme) with triangular aspect, divided in midline and with dispersed setae throughout the whole surface. Lamellae linguales (Ll) entirely separated by promentum. Trunk: Body with 60 to 65 rings. Collum (apodous ring) glabrous and depigmented (Fig. 4 A). Transverse lateral striae present. Terga with prozonite and metazonite distinct only by a transverse suture. Metazonite with striae in lateral region, being more closely spaced in the anterior region due to the smaller width of trunk (Fig. 4 B) (sutures variable among individuals). Opening of the repugnatorial glands starting from the fifth ring. Limbus smooth. Pre-anal ring depigmented (Fig. 4 C) with dorsal projection covering part of the anal valve; this with few setae on the opening. First Male Leg Pair (Fig. 5 A): The first leg pair is modified. Sternum reduced and not extending between the coxae (Cx). The coxae larger in comparison with the remaining legs. Pre-femur (Prf) with oral process parallel (P) to the coxae. Sensory bristles in the mesal region of process and small lobes on the surface of the anterior margin. The length of femur (F) is about 2 times longer than width. Post-femur (Psf) and tibia (Tb) with width similar to length. Tarsus with width 1.5 times shorter than length. Terminal claw not modified. Gonopod (Fig. 5 B): Structure is typical of the genus, composed of a reduced coxal part separated from telopodite by a rather vague lateral sulcus; telopodite terminating in two well-developed processes, one a seminal branch (solenomere, S) with a micro-squamate region, the other an internal branch (Ib), the latter densely setose. Gonopods relatively short and stout, about 2 times longer than wide, with a glabrous basal section (Bs) and a process (P) next to the sternal region, P supporting a seta. Basal section beset with papillae (Bb) extending onto a membranous area between coxal part and distal portion. The latter section (Ds) is 1.75 times longer than basal width and about 2.5 times shorter than Bs together with coxal part. Ds divided into a complex S and a digitiform Ib, both separated by a concave region (Sg, seminal groove?). S flattened and rounded, with a micro-squamate anteromedian face. Smooth region basal to S with a lateral lobe like a small shoulder (Sh). Ib somewhat shorter than S, with setae, presumably sensory ones, both at apex and lateral margin.Published as part of Iniesta, Luiz Felipe Moretti & Ferreira, Rodrigo Lopes, 2013, The first troglobitic Pseudonannolene from Brazilian iron ore caves (Spirostreptida: Pseudonannolenidae), pp. 85-95 in Zootaxa 3669 (1) on pages 86-91, DOI: 10.11646/zootaxa.3669.1.9, http://zenodo.org/record/28389
