Materials Examined
TYPE MATERIAL female holotype, 26 female and 4 male paratypes, from Dalbergia ecastaphyllum (L.) Taubert (Fabaceae), Cluny, Ste. Rose, Guadeloupe, 14 June 2002, coll. J. Etienne, on eight microscopic preparations in the collection of Departamento de Entomologia, Fitopatologia e Zoologia Agrícola, Universidade de São Paulo/ ESALQ, Piracicaba, São Paulo, Brazil. RELATION TO HOST vagrant on lower (abaxial) leaf surface.
Etymology
ETYMOLOGY The specific designation macrosetosus is derived from macro, Greek, long (not large!) and setosus, Latin, seta bearing, and refers to the long second ventral opisthosomal seta II (e).
Discussion
REMARKS A. macrosetosus brings the number of species of Acalitus in Guadeloupe up to eight. It is distinct in having a 6 rayed empodium and ventral opisthosomal seta I and II (d and e) subequal in length (4 or 5 rayed empodium and seta d from 1.3 to 2 times longer than seta e in the other species).
