Lycoderes albinoi Creao-Duarte & Cabral 2017, sp. nov.
No full textLycoderes albinoi Creão-Duarte & Cabral sp. nov. (Figs. 1–4) Diagnosis. Body dark brown, almost black, except for forewings, with large central hyaline area, and abdomen, yellow; anterior pronotal process vertical, elevated, with suprahumeral horns arising at apex, divergent in frontal view, spatulate, longer than wide, tricarinate; posterior process sickle-shaped, extending from base of anterior process, arched and well separated from scutellum anteriorly, distal half tectiform, tapering to acute apex, extended slightly beyond apex of clavus. Measurements (in millimeters): Male/female. Total length (head to apex of forewings) 5.85/6.06; pronotum length (projection of suprahumeral horns to apex of posterior process) 5.37/5.49; length of forewings 5.36/5,48; width between humeral angles 1.71/1.91; width of head across eyes 1.67/1.77; head height 0.88/0.94; distance between eyes 1.12/1.23; distance between ocelli 0.46/0.50. Description. Holotype male. Coloration. Head, pronotum, ventral surface of thorax and legs dark brown, except for central area of forewings, hyaline, and eyes, ocelli and abdomen, yellow; head, legs and thorax with whitish and waxy pubescence; hind tibiae light brown, and tarsi yellow. Head (Fig. 2). Approximately 1.5x wider than long, eyes hemispherical, ocelli small, above centro-ocular line; postclypeus trilobed in frontal view. Thorax. Pronotum (Fig. 1) densely punctate, punctations coarser on posterior process; short, decumbent setae throughout; median carina weaker in metopidium, percurrent and sharper along posterior process; suprahumeral horns Vshaped in anterior view, spatulate, longer than wide, tri-faceted, delimited by carinae on anterior and posterior margins and on ventral surface from apex to base of posterior process; in lateral view, metopidium slightly curved anteriorly, short, not exceeding suprahumeral horns in length; posterior process sickle-shaped, extending from base of anterior process, sharply curved and well separated from scutellum anteriorly, distal half tectiform, tapering towards acute apex, reaching beyond apex of clavus; forewings (Fig. 1) obliquely truncate at apex; one discoidal cell, five apical cells: fourth cell triangular, not petiolate, and fifth cell pentagonal; two crossveins: r-m fused to branch M1+2 and m-cu to branches M3+4. Legs with tibiae spatulate, metathoracic tibiae with cucullate setae in distal half of row II. Female (Figs. 3,4): similar to male, slightly larger and lighter in color; proximal half of posterior process less sharply curved. Material examined. Holotype male, “ Brasil, BA[HIA], Uma | Fazenda UNACAU | 7-24.X.1986 /D. S. Amo- | rim & C. Vasconcelos ”; “ Mata Atlântica Primária | Armadilha Luminosa ” (DSEC / UFPB). Paratype female with same label data as holotype. Notes on type specimens. Specimens in good state of preservation. The holotype lacks the right suprahumeral horn. The left suprahumeral horn is missing in the female paratype, as well as the tarsi of both metathoracic legs. There is slight variation in the position of the crossvein r-m in the type series, however, in both the holotype and the paratype it is located at the base of M1+2 after the M fork. The crossvein r-m is a little farther from the fork in the holotype’s left forewing, and right after the point of bifurcation of M in the right forewing of the female, which is anomalous in this regard. In all cases, the fourth apical cell in the forewings is distinctly triangular. Remarks. In comparison to other congeneric species, Lycoderes albinoi sp. nov. most closely resembles Lycoderes ancora (Germar) and Lycoderes furcifer Sakakibara. In females of Lycoderes ancora, the suprahumeral horns diverge next to the base of the posterior process, whereas in females of Lycoderes. albinoi sp. nov., the anterior process is more elongate, so that the suprahumeral horns diverge farther from the base of the posterior process. In males of Lycoderes ancora, the base of the posterior process is wider, reaching the base of the suprahumeral horns, a condition that is not observed in males of Lycoderes albinoi sp. nov. due to the much narrower base of the posterior process. The base of the posterior process is also close to the base of the suprahumeral horns in males and females of Lycoderes furcifer, however, the tip of the posterior process does not reach the apex of the clavus, as it does in Lycoderes albinoi sp. nov. In males of Lycoderes furcifer, the suprahumeral horns are tapered acutely towards the distal tips, and slightly curved ventrally. Contrastingly, the suprahumeral horns are gradually broadened toward the distal half in males of Lycoderes albinoi sp. nov., forming a dorsal angle in frontal view, then tapering from the distal third to an acute tip. Etymology. This species is dedicated to Dr. Albino Morimasa Sakakibara, for his lifelong work training new systematists focused on auchenorrhynchan Hemiptera, and for his outstanding contributions to treehopper taxonomy.Published as part of Creão-Duarte, Antonio José, Cabral, Valberta Alves & Lourenço, Aline, 2017, A new species of Lycoderes Sakakibara (Hemiptera, Membracidae, Stegaspidinae) from Brazil in Zootaxa 4281 (1), DOI: 10.11646/zootaxa.4281.1.5, http://zenodo.org/record/81577
Protocolo de coleta e diversidade de Membracidae (Hemiptera: Auchenorrhyncha) em áreas de Mata Atlântica da Paraíba
No full textThe family Membracidae comprises about 3.200 described species and is distributed worldwide (with the exception of the Arctic and Antarctic). Although the greatest diversity is found in the Neotropics, few ecological studies have been directed to this group in Brazil. The present study aimed to establish a sampling protocol, as well as to inventory and analyze the similarity of the fauna of treehoppers in areas of the Atlantic Forest of Paraíba. The protocol was standardized in 100 sampling units and four sampling techniques were used: active collection (30 units), yellow adhesive cards placed in the understory (30 units) and in the canopy (30 units) and light trap (10 units). Samples were collected in four representative areas of Atlantic Forest in the state: REBIO Guaribas (3,016ha), RPGN Engenho Gargaú (1,058.6ha), RPPN Fazenda Pacatuba (266,53ha) and RVS Mata do Buraquinho (519,75ha). To evaluate the efficiency of the protocol, the performance was analyzed through rarefaction, and the complementary of the methods was analyzed through the Jaccard index. Species accumulation curves were also made using the Chao 1 and Chao 2 estimators and the sample sufficiency was calculated in each area. The similarity between the areas was evaluated for abundance (ANOVA) and richness (ANOSIM). The richness of the Atlantic Forest was estimated through Chao 1 and Chao2. In total, 2,612 individuals belonging to 85 species were collected. The methods showed high complementarity with values varying from 63% to 78%. The richness sampled in the areas varied between 34 and 58 species, with an average of 85.2% of sample sufficiency. The RPPN Engenho Gargaú and REBIO Guaribas differed (p = 0.034) with regard to species abundance. The results show that the taxocenosis of treehoppers among sampled areas are similar both in composition and patterns is species distribution and abundance.A família Membracidae compreende cerca de 3.200 espécies descritas e tem distribuição cosmopolita (com exceção do Ártico e Antártico). Apesar de a maior diversidade ser encontrada nos Neotrópico, poucos estudos de cunho ecológico têm sido direcionados a este grupo no Brasil. O presente estudo objetivou o estabelecimento de um protocolo de amostragem, bem como, inventariar e analisar a similaridade da fauna de membracídeos em áreas da Mata Atlântica da Paraíba. O protocolo foi padronizado em 100 unidades amostrais e foram utilizados quatro métodos de coleta, sendo: coleta ativa (30 unidades), cartões adesivos amarelos aplicados no sub-bosque (30 unidades) e no dossel (30 unidades) e armadilha luminosa (10 unidades). Foram realizadas coletas em quatro áreas representativas de Mata Atlântica do estado: REBIO Guaribas (3.016ha), RPPN Engenho Gargaú (1.058,6ha), RPPN Fazenda Pacatuba (266,53ha) e RVS Mata do Buraquinho (519,75ha). Para avaliar a eficiência do protocolo, foi analisado o desempenho, através da rarefação, e a complementaridade dos métodos por meio do índice Jaccard. Também foram feitas curvas de acumulação de espécies utilizando os estimadores Chao 1 e Chao 2 e calculada a suficiência amostral em cada área. A similaridade entre as áreas foi avaliada quanto à abundância (ANOVA) e riqueza (ANOSIM). A riqueza da Mata Atlântica foi estimada através de Chao 1 e Chao 2. No total foram coletados 2.612 indivíduos pertencentes a 85 espécies. Os métodos apresentaram alta complementaridade com valores variando de 63% a 78%. A riqueza amostrada nas áreas variou entre 34 e 58 espécies, com média de 85,2% de suficiência amostral. A RPPN Engenho Gargaú e REBIO Guaribas diferiram (p= 0.034) com relação a abundância de indivíduos. Os resultados mostram que a taxocenose de membracídeos entre as áreas de estudo são similares tanto na composição quanto no padrão de distribuição de abundânci

The appearance and small size of the suprahumeral horns, as well as their location on the pronotum—posterior to the humeral anglesdistinguish this species from all others in the genus. No obvious variation in these features was observed in the type series, and males and females are not sexually dimorphic with regard to pronotal shape as in many other congeneric species. Observed intraspecific variation is limited to the presence of a third <i>m-cu</i> crossvein in some specimens, general coloration and distribution of wax coating on the body surface (illustrated in Figs. 3, 13–16). Whereas the holotype is dark brown with irregularly distributed reddish (anteriorly) and yellow (posteriorly) patches on the pronotum, others may be entirely reddish brown (Figs. 13–14) or pale brown with black spots on the metopidium and pronotum dorsally, and mottled yellow at the apex of the posterior process (Figs. 3, 15–16). In the latter case, these specimens could be teneral adults. Alternatively, some specimens exhibit a white wax residue that may cover the entire body, especially in females (Fig. 14). The eyes of some specimens became red after they were removed from the drying oven.</p> <p> In addition to its remarkable pronotal features, the metathoracic tibia in <i>N. sakakibarai</i> <b>sp. nov.</b> exhibits small cucullate setae distributed along row III, a feature not previously reported for Hypsoprorini (Fig. 32; discussed in ‘ <i>notes on relevant taxonomic characters</i> ’).</p> <p> <b>Etymology</b>. This species is named for Dr. Albino Morimassa Sakakibara, in honor of his many career achievements.
