AbstractDescriptions are given of two new species of pentatomid bug, one known to transmit the disease ‘marchitez’ (caused by Phytomonas staheli) of oil palm in Ecuador and the other associated with hartrot (caused by the same flagellate) in coconut palm in French Guiana. Notes are included on a third species also associated with hartrot in French Guiana. The species are Lincus lethifer sp.n., L. apollo sp.n. and L. croupius Rolston.

Table Mountains

Baetidae is one of the most diverse families of Ephemeroptera. In South America this family now encompasses 27 genera and more than 130 species. The Guyana region is known for its extraordinary diversity and high level of endemism, which is, above all, remarkable at the tops of the isolated flat-topped table mountains – tepuis. Recently various international speleological expeditions to Churí-tepui explored the cave systems of this mountain. Here we describe a new genus of Baetidae recently found during the mentioned expeditions to Churí-tepui and Auyán-tepui. Parakari n. gen. can be distinguish from the other genera of this family, among other characters, in the nymphs by the absence of abdominal gills I, tarsal claws with subapical denticle larger than the others, right mandible with prostheca bifid and pectinate and with incisors positioned in obtuse angle to mola area, lingua with a tuft of setae, segment II of maxillary palpi with a concavity and a hole apically and segment II of labial palpi with a strong distomedial projection. In the adults the hind wings are absent and genitalia with segment II of forceps with a constriction, segment III elongate and long. Two new species are included in this genus; each one was collected at different tepui. A key and illustrations are included.

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.

Two New Species

Abstract Two new species of Lessingianthus (Asteraceae: Vernonieae) are described and illustrated. One of these, L. foliosus Dematt., bears a resemblance to L. vepretorum, but can be separated from it by its linear leaves, that are lanate on the abaxial surface, and by its shorter internodes. The other new species, L. lapinhensis Dematt., can be easily separated from L. brevifolius and other taxa of the genus by the combination of stems 8-18 cm tall, glabrous linear leaves and campanulate involucres. Thirteen other taxa previously described as Vernonia are transferred to the genus Lessingianthus and two lectotypes are designated here.

Two New Species

Lasiancistrus (Loricariidae: Hypostominae: Ancistrini) is diagnosed by the unique presence of a ventral strut of the pterotic and the presence of whiskerlike odontodes on the snout. Lasiancistrus has about 16 species assigned to it; however, only four are valid (L. schomburgkii, L. caucanus, L. guacharote, and L. heteracanthus), L. nationi is an Ancistrus, and L. trinitatus is incertae sedis in the Loricariidae. Lasiancistrus maracaiboensis and L. mystacinus are synonyms of L. guacharote; L. pictus, L. castelnaui, L. caquetae, L. guapore, L. multispinis, and L. scolymus are synonyms of L. schomburgkii; and L. planiceps, L. mayoloi, and L. volcanensis are synonyms of L. caucanus. Two new species are described: L. tentaculatus from the río Orinoco basin and L. saetiger from the rio Guama. The species can largely be told apart via color (L. schomburgkii has no or white spots on the fins, L. saetiger has entirely gray fins, and the rest have black spots in the fins), the presence of abdominal plates (L. caucanus, L. saetiger, and L. tentaculatus have naked abdomens, L. guacharote has a few small plates near the insertion of the pectoral fin, L. heteracanthus has a large patch of small plates, and L. schomburgkii is variable), and nuptial male condition (L. tentaculatus has small tentacles along the edge of the snout and the other species have a patch of whisker-like odontodes at the corners of the snout). Most species are widespread in piedmont regions of South America with L. schomburgkii occurring in the Amazon, Orinoco, and Essequibo basins.

The descriptions are accompanied by figures illustrating the male and female habitus ofA.theranyi, the male habitus ofA.camachoi, and male genitalia of both species.Amazonopsistheranyiexhibits pronounced secondary sexual dimorphism which likewise may be a characteristic of the genus.Amazonopsismales have modified protarsal and mesotarsal claws, a pair of small spines on the anterior prosternum, and a pair of ventrally directed processes on the posterior metaventrite. Females ofA.theranyidisplay a pair of unique, oval perforations in the cuticle of the pronotum and have unmodified claws; females ofA.camachoiare unknown. Descriptions are furnished of the stream habitats and microhabitats where the study specimens were collected.

Two New Species

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.
