Pentatomid bugs (Hemiptera) that transmit a flagellate disease of cultivated palms in South America

Abstract

Descriptions are given of two new species of pentatomid bug,

New records and update on the geographic distribution of fifteen species of Lincus Stål, 1867 (Insecta: Hemiptera: Pentatomidae) associated with palms and coconut trees in the Neotropics

“…As mentioned by Dolling (1984), the female of L. apollo runs to L. styliger Breddin in Rolston's (1983) key, but they can be differentiated by the smaller dimensions of L. apollo. In addition, the posterolateral angles of the pygophore are apically emarginate in L. apollo, and obtuse in L. styliger.…”

“…Lincus is distributed exclusively in the Neotropical region, already recorded in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Panama, Peru, Surinam, and Venezuela. The majority of described species are from Peru (Rolston 1983(Rolston , 1989Dolling 1984;Couturier & Kahn 1989, 1992Llosa et al 1990;Dollet et al 1993;Di Lucca et al 2013;Maciel et al 2015;Campos & Roell 2017). Lincus was revised in the late 20 th century by Rolston (1983) who provided the description of the majority of currently known species and a key to their identification.…”

“…Lincus was revised in the late 20 th century by Rolston (1983) who provided the description of the majority of currently known species and a key to their identification. Soon after, Dolling (1984) described two new species, L. lethifer and L. apollo, and included notes about L. bipunctatus (as L. croupius) pointing out these species as transmitters of diseases caused by tripanossomatids in coconut and palms. Rolston (1989) described three new species found in palms in Peru;L.…”

“…hebes, L. malevolus and L. spurcus, and Campos & Roell (2017) described L. curvatus collected in palms in Ecuador. Currently, Lincus comprises 36 described species (Rolston 1983a(Rolston , 1989bDolling 1984;Campos & Grazia 2006;Grazia et al 2015;Campos & Roell 2017), and 15 of them have already been reported on palms and coconut trees (Stahel 1954;Desmier de Chenon 1984;Dolling 1984;Louise et al 1986;Resende 1986;Rolston 1989;Camargo 1999;Alves de Souza 2000;Panizzi et al 2000;Mitchel 2004;Di Lucca et al 2013;Maciel et al 2015;Campos & Roell 2017).…”

“…Dolling, 1984 Figures 1A, 2, 3A; Tables 1, 2 Body brown, length between 10.2-10.9 mm, with 1 + 1 yellowish spots on humeral angles, and on apex of radial veins. Mandibular plates longer than clypeus; apex of mandibular plates and clypeus light brown, slightly translucent on apex.…”
