Nine species of Mallophaga from Peruvian birds are reported in this work. Two Mallophaga Amblycera: Heteromenopon laticapitis y Menacanthus pici, as well as seven Mallophaga Ischnocera: Alcedoffula theresae, Brueelia brunneinucha, Chelopistes meleagridis, Columbicola columbae, Paragoniocotes aratingae, Penenirmus jungens y Saemundssonia (Saemundssonia) lari, were identified morphologically. A brief description of each chewing lice and discussion about their hosts and distribution is done.
ABSTRACT
Chewing lice were collected from small shorebirds (Charadriformes: Scolopacidae) overwintering in foraging grounds of coastal Ecuador. On 27 occasions at least one louse (3.7%) was collected from six host species. Based on external morphological characters, at least two species of chewing lice could be preliminary identified (family: Menoponidae), including Actornithophilus umbrinus (Burmeister, 1842) and Austromenopon sp. A. umbrinus was found in the Western Sandpiper (Calidris mauri), Least Sandpiper (C. minutilla), Stilt Sandpiper (C. himantopus), Semipalmated Plover (Charadrius semipalmatus) and Wilson's phalarope (Phalaropus tricolor), while Austromenopon sp. is presumably the first record collected from the Surfbird (Aphriza virgata). These findings indicate that the distribution of these chewing lice species covers at least the regions around the equator (latitude 0°) until the Arctic in the north, but probably also includes the entire winter distribution area of the host species. This is the first study of chewing lice from Ecuador's mainland coast and more research is required to understand the host-parasite ecology and ectoparasitic infection in shorebirds stopping over the region.
Piolhos mastigadores foram coletados em pequenas aves marinhas (Charadriformes: Scolopacidae) que invernavam na zona de forrageamento na costa do Equador. Em 27 ocasiões, pelo menos um piolho (3,7%) foi coletado em seis espécies de hospedeiros. Com base em caracteres morfológicos externos, pelo menos duas espécies de piolhos mastigadores foram preliminarmente identificados (família: Menoponidae), incluindo Actornithophilus umbrinus (Burmeister, 1842) e Austromenopon sp. A. umbrinus foi encontrado em Pilrito-miudo (Calidris mauri), Pilrito-anão (C. minutilla), Pilrito-pernilongo (C. himantopus), Borrelho-semipalmado (Charadrius semipalmatus) e o Falaropo de Wilson (Phalaropus tricolor), enquanto Austromenopon sp. é, presumivelmente, o primeiro registro coletado na Ave-Surfista (Aphriza virgata). Esses resultados indicam que a distribuição dessas espécies de piolhos mastigadores abrange pelo menos as regiões ao redor do Equador (latitude 0°) até o Ártico, no Norte, mas provavelmente também inclui toda a área de distribuição de inverno essas espécies hospedeiras. Este é o primeiro estudo de piolhos de aves marinhas da área continental do Equador e mais pesquisas são necessárias para compreender a ecologia parasita-hospedeiro e ectoparasitose destas aves que invernam na região.

Thirty-two specimens of Columbina picui (picui ground-dove) were examined, and a collection of arthropods was made by washing the external surface of the body and the nasal cavity. The species in the order Phthiraptera found and their respective prevalences, mean abundance and mean intensity were: Columbicola passerinae (84.4%; 10.3; 12.2), Hohorstiella passerinae (21.9%; 0.7; 3.1) and Physconelloides eurysema (3.1%; 0.1; 2). The gamasid mites found in the birds and their respective prevalences, mean abundance and mean intensity were: Pellonyssus marui (31.3%; 1.2; 3.9), Ornithonyssus bursa (15.6%; 0.2. ;1.2) and Mesonyssus sp. (6.3%; 0.1; 1). Columbicola passerinae, H. passerinae, P. eurysema, O. bursa, P. marui and Mesonyssus sp. were recorded for the first time infecting C. picui in Brazil. Except for O. bursa, the other species are reported for the first time in the state of Rio Grande do Sul, Brazil.
Foram examinados 32 espécimes de Columbina picui (rolinha-picui), sendo que a coleta de artrópodes foi realizada por meio de lavagem da superfície externa do corpo e da cavidade nasal. As espécies da ordem Phthiraptera encontradas e suas respectivas prevalências, abundância média e intensidade média foram: Columbicola passerinae (84,4%; 10,3; 12,2), Hohorstiella passerinae (21,9%; 0,7; 3,1) e Physconelloides eurysema (3,1%; 0,1; 2). Os ácaros Gamasida encontrados nas aves e suas respectivas prevalências, abundância média e intensidade média foram: Pellonyssus marui (31,3%; 1,2; 3,9), Ornithonyssus bursa (15,6%; 0,2; 1,2) e Mesonyssus sp. (6,3%; 0,1; 1). Columbicola passerinae, H. passerinae, P. eurysema, O. bursa, P. marui e Mesonyssus sp. são relatados pela primeira vez parasitando C. picui no Brasil. Exceto O. bursa, as demais espécies são relatadas pela primera vez no estado do Rio Grande do Sul, Brasil.
