New and little known species of the genus Martiodrilus Michaelsen, 1936 from French Guiana (Oligochaeta, Glossoscolecidae)

The genus Martiodrilus is native to South America, with two species, Martiodrilus tenkatei (Horst, 1887) and Martiodrilus duodenarius (Michaelsen, 1918), previously recorded from French Guiana. In this paper we verified the presence of both species in French Guiana and provided a new record, Martiodrilus (Botaria) helleri (Michaelsen, 1918). Furthermore, two new species were described: Martiodrilus (Botaria) dewynteri sp. nov. and Martiodrilus (Maipure) gaucheri sp. nov. The subgeneric division of the genus Martiodrilus is briefly discussed.

A New Species

A new species, Gabrita erwini, sp. nov. in the tribe Gabritini is described and illustrated from Ecuador, representing the first record of the genus and tribe in northwestern South America which extends its distribution across the Neotropical region from eastern localities in the countries of Brazil, French Guiana and Guyana. Three new species of Sandersellus in the tribe Sandersellini are described and illustrated: S. bigladius, sp. nov. from Bolivia, S. digitatus, sp. nov. from Brazil and S. bilanceus, sp. nov. from Peru. Brazil is a new record for the genus and tribe and extends the distribution eastward from its formerly known western range in Peru, Bolivia and Panama. Taxonomy is reviewed, a revised key to known males and distribution of the known species of Gabrita and Sandersellus are provided.

Records of 48 species belonging to the order Arthoniales from Bolivia are presented. Cryptothecia rosae-iselae Flakus & Kukwa and Lecanactis minuta Ertz, Flakus & Kukwa are described as new to science. Thirty-seven species are reported for the first time from Bolivia, seven of which, Alyxoria apomelaena, Cryptothecia darwiniana, C. groenhartii, C. megalocarpa, Herpothallon furfuraceum, Lecanographa uniseptata, and Opegrapha subvulgata, are new to South America. This raises the number of Arthoniales known from the country up to 72. Two new combinations are proposed: Alyxoria apomelaena (A. Massal.) Ertz for Opegrapha apomelaena A. Massal. and Myriostigma napoense (Kalb & Jonitz) Kukwa for Cryptothecia napoensis Kalb & Jonitz. Cresponea melanocheiloides is the second species of the genus shown to contain a xantholepinone. Cresponea melanocheiloides is reported as new to Costa Rica and Panama, Cryptothecia megalocarpa as new to the Netherlands Antilles and Guyana and C. striata is new to Colombia, Costa Rica, French Guiana and the Netherlands Antilles. Distribution data are reported for each species, with taxonomic remarks provided for new and some problematic taxa.

The fasciolariid fauna from two expeditions to French Guiana is examined and augmented with published records and material of other collections from the Guianas and northeastern Brazil. Twelve species of Fasciolaria and Aurantilaria (Fasciolariinae), Aristofusus, Lyonsifusus and Fusinus s.l. (Fusininae), and Lamellilatirus and Polygona (Peristerniinae) are reported and discussed. Nine species are represented in expedition collections, and reports of three other species are evaluated. Two morphologically distinct species of Lamellilatirus are described as new; type localities of both are off French Guiana, 114–118 m. Ten Guianan fasciolariids range variously northward to Caribbean South America and the Lesser Antilles and southward to Ceará, Brazil; one other extends into the northern Caribbean, and one extends southward to Rio de Janeiro, Brazil.

A New Species

Abstract—A synopsis of Dicliptera (Acanthaceae) for Brazil is presented. Six species are recognized: Dicliptera ciliaris, D. sexangularis, and D. squarrosa, widely distributed in South America; D. purpurascens, which ranges from the North Region of Brazil (in the state of Acre) to eastern Bolivia; D. gracilirama, a new species from the Atlantic Forest of northeastern Brazil; and D. granchaquenha, a new species recorded in dry and semideciduous forests in Bolivia and western Brazil, in the state of Mato Grosso do Sul. Furthermore, we propose new synonyms and designate lectotypes for eleven names. An identification key to the six accepted Dicliptera species in Brazil is provided.
