The material on which this paper is based was received by Prof. R. T. Leiper from several sources, and includes specimens collected in British Guiana by the Filariasis Commission, in West Africa by Dr. Yale Massey, and in New Guinea by Dr. G. M. Heydon. In addition there was a tube received from Dr. O'Connor from Samoa labelled on the outside of the bottle “Pig, Samoa, Ank. Duod. from intestine,” and inside (presumably by Dr. Clayton Lane) “Crassisoma samoense.” It contained specimens of the latter species only. The type material of Lane's two new species from the pig was also available for examination.

The sabellid genera Anamobaea Krøyer, 1856 and Notaulax Tauber, 1879 are two of the most attractive polychaete worms in coral reefs. Anamobaea is represented by two Caribbean species and Notaulax with 24 species from around the world, six of them previously known to tropical America. During examination of fouling biota and sclerozoans from Mexico, Anamobaea orstedii Krøyer, 1856 was found in coral reefs from the southern Gulf of Mexico and three species of Notaulax were identified to the Mexican Pacific, two of them being new species to science. Anamobaea orstedii Krøyer, 1856 is first reported as sclerozoan of dead coral from the southern Gulf of Mexico. An amendment to the generic diagnosis of Anamobaea is provided, based on the presence of a higher number of skeletal cells than previously recorded; height, shape and exposition of the anterior peristomial ring; the non-fusion of dorsal collar margins to faecal groove; shape of collar chaetiger and abdominal chaetae and distribution and shape of radiolar ocelli. Notaulax californica (Treadwell, 1906) is reported as fouling in buoys and docks from the Gulf of California. Two new species of Notaulax are described: the former was found in hull and dock fouling from La Paz (Gulf of California) and the second one as sclerozoan of oysters from a dock fouling in Acapulco (south Mexican Pacific). In addition, reproductive features are described for the first time for A. orstedii which is a simultaneous hermaphrodite with female and males gametes found within the same segments of abdominal region. Oocytes develop synchronously and sperm morphology (spherical nucleus and rounded acrosome, four spherical mitochondria and a long free flagellum) suggest an adaptation to broadcast spawning and external fertilisation. Species of Notaulax here examined were gonochoric, with gametes distributed in abdominal segments.

Based on morphological and phylogenetic data, two new species in the Inonotus linteus complex (Hymenochaetales, Basidiomycota), Inonotus pseudolinteus and I. sideroxylicola, are described from tropical America. In addition, a new combination, Inonotus dependens, is proposed. Previously, the species was treated as Phellinus dependens (Murrill) Ryvarden. However, it is phylogenetically related to the Inonotus linteus complex. Its description is given based on our recent collections. An identification key to tropical species of Inonotus linteus complex is provided.

Actinopus Perty, 1833 is characterized and redescribed, including 80 species occurring from Panama to Argentina. Eighteen previously known species are redescribed: A. rufipes (Lucas, 1834); A. longipalpis C. L. Koch, 1842; A. nattereri (Doleschall, 1871); A. crassipes (Keyserling, 1891); A. robustus (O. Pickard-Cambridge, 1892); A. wallacei F. O. P.-Cambridge, 1896; A. princeps Chamberlin, 1917; A. xenus Chamberlin, 1917; A. fractus Mello-Leitão, 1920; A. paranensis Mello-Leitão, 1920; A. pusillus Mello-Leitão, 1920; A. dubiomaculatus Mello-Leitão, 1923; A. trinotatus Mello-Leitão, 1938; A. cucutaensis Mello-Leitão, 1941; A. echinus Mello-Leitão, 1949; A. clavero Ríos-Tamayo & Goloboff, 2018; A. gerschiapelliarum Ríos-Tamayo & Goloboff, 2018; and A. palmar Ríos-Tamayo & Goloboff, 2018. Additionally, A. tarsalis Perty, 1833, the type species, A. insignis (Holmberg, 1881) and other 18 species recently described species from Argentina and Bolivia, are re-evaluated. Forty-two new species are described: Actinopus castelo sp. nov., A. apalai sp. nov., A. mairinquensis sp. nov., A. obidos sp. nov., A. buritiensis sp. nov., A. pinhao sp. nov., A. ducke sp. nov., A. hirsutus sp. nov., A. jaboticatubas sp. nov., A. confusus sp. nov., A. pampulha sp. nov., A. candango sp. nov., A. paraitinga sp. nov., A. cornelli sp. nov., A. vilhena sp. nov., A. harveyi sp. nov., A. itapitocai sp. nov., A. ipioca sp. nov., A. itaqui sp. nov., A. xingu sp. nov., A. mesa sp. nov., A. caxiuana sp. nov., A. utinga sp. nov., A. emas sp. nov., A. bocaina sp. nov., A. osbournei sp. nov., A. dioi sp. nov., A. tutu sp. nov., A. azaghal sp. nov., A. itacolomi sp. nov., A. parafundulus sp. nov., A. urucui sp. nov., A. reznori sp. nov., A. anselmoi sp. nov., A. guajara sp. nov., A. apiacas sp. nov., A. jamari sp. nov. from Brazil; A. laventana sp. nov. from Argentina and Uruguay; A. lomalinda sp. nov. from British Guiana and Colombia; A. concinnus sp. nov. from Venezuela and Brazil; A. pindapoy sp. nov. from Argentina; A. panguana sp. nov. from Peru. The females of A. dubiomaculatus and A. cucutaensis and the males of A. nattereri are described for the first time. New records are presented for A. clavero; A.crassipes; A. dubiomaculatus; A. fractus; A. gerschiapelliarum; A. nattereri; A. palmar; A. paranensis; A. princeps, A. pusillus, A. robustus and A. wallacei. Ten old species names are herein considered species inquirendae: A. caraiba (Simon, 1889); A. harti Pocock, 1895; A. liodon (Ausserer, 1875); A. nigripes (Lucas, 1834); A. pertyi Lucas, 1843; A. piceus (Ausserer, 1871); A. rojasi (Simon, 1889); A. rufibarbis Mello-Leitão, 1930; A. scalops (Simon, 1889) and A. valencianus (Simon, 1889). Most species presently recognized were included in 11 informal groups based mainly on male palpal characters. A key for these groups plus three species, not included in any group, but known from males, is presented.
