Systematics of Otarrha, a new Neotropical subgenus of Chimarra (Trichoptera: Philopotamidae)

Abstract. Subgenus Otarrha is established in genus Chimarra to include eighteen described species formerly placed either in subgenus Chimarra or unplaced to subgenus, and thirteen new species. All species are Neotropical, with collective distributions primarily in the Antilles (Greater and Lesser) and northern South America. One species occurs in southeastern Brazil and another species in Costa Rica and Panama. New species are described, recognized species redescribed (except for C. diannae and C. koki ), and a key to the identification of males in the subgenus is provided. Additionally, characters supporting monophyly of the subgenus and a phylogeny of its species are proposed. Described species transferred to this subgenus include Chimarra cubanorum Botosaneanu, C . diakis Flint, C . diannae Flint & Sykora, C . dominicana Flint, C . garciai Botosaneanu, C . guapa Botosaneanu, C . jamaicensis Flint, C . koki Botosaneanu, C . machaerophora Flint, C . patosa Ross, C . puertoricensis Flint, C . quadrifurcata Botosaneanu, C . retrorsa Flint, C . rossi Bueno-Soria, C . sensillata Flint, C . septemlobata Flint, C . septifera Flint and C . spinulifera Flint. Chimarra patosa is designated the type species of the subgenus. New species described in Otarrha include Chimarra amazonia (Peru), C . barinas (Venezuela), C . darlingtoni (Cuba), C . diaphora (Venezuela), C . incipiens (Venezuela), C . odonta (Brazil), C . parene (Peru), C . parilis (Peru), C . particeps (Peru), C . peruana (Peru), C . phthanorossi (Colombia), C . redonda (Dominican Republic) and C . tachuela (Venezuela). Two additional species are described and left incertae sedis to subgenus, Chimarra usitatissima Flint and C . angularis , sp.n. (Venezuela, Guyana).     

New species and records of Chimarra (Trichoptera,Philopotamidae) from Northeastern Brazil,and an updated key to subgenus Chimarra (Chimarrita)

Two new species of Chimarra (Chimarrita) are described and illustrated, Chimarra (Chimarrita) mesodonta sp. n. and Chimarra (Chimarrita) anticheira sp. n. from the Chimarra (Chimarrita) rosalesi and Chimarra (Chimarrita) simpliciforma species groups, respectively. The morphological variation of Chimarra (Curgia) morio is also illustrated. Chimarra (Otarrha) odonta and Chimarra (Chimarrita) kontilos are reported to occur in the northeast region of Brazil for the first time. An updated key is provided for males and females of the all species in the subgenus Chimarrita.     

New Neotropical species of Chimarra (Trichoptera, Philopotamidae)

Ten new Neotropical species of Chimarra are described in the subgenera Chimarra, Chimarrita, and Otarrha. New species in the subgenus Chimarra include, in the Chimarra ortiziana group: Chimarra calorisp. n. (southeastern Brazil) and Chimarra onchyrhinasp. n. (Venezuela); in the Chimarra picea group: Chimarra inchoatasp. n. (Venezuela), Chimarra nicehuhsp. n. (Venezuela), and Chimarra sunimasp. n. (Colombia); and in the Chimarra poolei group: Chimarra caucasp. n. (Colombia) and Chimarra desiraesp. n. (Bolivia). New species in the subgenus Chimarrita include, in the Chimarra simpliciforma group: Chimarra curvipenissp. n. (SE Brazil) and Chimarra latiforcepssp. n. (SE Brazil). A single new species in the subgenus Otarrha is also described: Chimarra soroasp. n. (Cuba). Males and females for all of the new species are illustrated, except for Chimarra desirae, for which female specimens were unavailable. Additionally, the female of Chimarra (Chimarrita) camella, which was previously unknown, is illustrated.     

Four new species of Chimarra Stephens (Trichoptera: Philopotamoidea: Philopotamidae) from Indian Himalaya

Four new species are added to the philopotamid fauna of India. The newly described species under Chimarra Stephens are Chimarra barnardi sp. nov. and C. padami sp. nov. (both from Arunachal Pradesh), C. bidenta sp. nov. from Uttarakhand and C. quadrata sp. nov. from Sikkim. These species are distinguishable from each other as well as from previously known allied species by consistent variation in the structure of inferior appendages, tergite X and the phallic apparatus of males.     

Taxonomic revision of the genus Dolophilodes subgenus Dolophilodes (Trichoptera: Philopotamidae) of Japan

Japanese species of the genus Dolophilodes subgenus Dolophilodes are revised taxonomically. Seven described species are recognized: D. japonicus (Banks), D. shinboensis (Kobayashi), D. auriculatus Martynov, D. nomugiensis (Kobayashi), D. babai (Kobayashi), D. iroensis (Kobayashi) and D. commatus (Kobayashi). In addition, two new species, D. angustatus and D. dilatatus, are described. Males of all nine species and females of all but D. babai are described and illustrated. The subgenus Hisaura Kobayashi is synonymized under the subgenus Dolophilodes. Three synonymies of species proposed are Wormaldia triangulata Kobayashi under D. nomugiensis, D. kunashirensis Ivanov under D. iroensis and Sortosa kaishoensis Kobayashi under D. commatus.     

Philopotaminae of Madagascar (Trichoptera: Philopotamidae)

The Malagasy fauna includes two genera of Philopotaminae: Wormaldia McLachlan 1865 and an endemic new genus, Ranarijaodes n. gen. The Malagasy and African (sensu stricto) lineages of Wormaldia are distinct. Apomorphic characters (the shape of the phallic apparatus for the African species and the splitting of the median lobe of the tenth tergite for the Malagasy species) confirm their separation. New captures are reported for two of the four previously known species of Wormaldia. Seven new species are described: Wormaldia ambahibeae n. sp., W. faharoa n. sp., W. fahatelo n. sp., W. randriamasimananai n. sp., W. fahefatra n. sp., W. legrandi n. sp. and W. fahadimy n. sp. Ranarijaodes n. gen. is close to Dolophilodes Ulmer 1909. It is described for the three new species Ranarijaodes fiana n. sp., R. angapi n. sp. and R. atsimo n. sp. The 14 Malagasy species of Philopotaminae are endemics of the island. Their geographical distributions and ecological preferences are described and discussed.     

Two new species of caddisflies from East Asia （Trichoptera： Philopotamidae, Psychomyiidae）

A new species of Kisaura Ross （Philopotamidae） from Japan and a new species of Psychomyia Latreille （Psychomyiidae） from Russia are described. Kisaura imparis n. sp. is closest to Kisaura aurascens （Martynov, 1934）, but the lateral processes of tergum X are asymmetrical and the apex of tergum X is different. Psychomyia poltavkaensis n. sp. resembles Psychomyia n. sp., but the shape of tergum IX＋X is more rounded, the apex of the basoventral process of each preanal appendage is unforked, and the inferior appendages are branched.

Revision of the Neotropical genus Chimarrhodella Lestage (Trichoptera: Philopotamidae)

Abstract. A revision and phylogenetic analysis of the Neotropical genus Chimarrhodella Lestage is presented. Four described species are recognized, C.galeata (Martynov), C.peruviana (Ross), C.ulmeri (Ross) and C.nigra Flint. In addition, five new species are described, C.costaricensis sp.n. (Costa Rica), C.tapanti sp.n. (Costa Rica), C.flinti sp.n. (Venezuela), C.pilcopata , sp.n. (Peru) and C.tobagoensis sp.n. (Tobago). These species are organized into two monophyletic species groups, designated here the Galeata Group and the Peruviana Group. The Galeata Group is characterized by having male genitalia with tergum X possessing well developed lateral lobes bearing sclerotized, spine-like processes and includes C.galeata, C.costaricensis, C.flinti, C.pilcopata and C.tapanti. The Peruviana Group is characterized by having male genitalia with tergum X only slightly divided apically, tergum IX bearing hook-like processes posteriorly, and female genitalia with segment VIII much elongated in comparison to the Galeata Group and includes C.peruviana, C.nigra, C.tobagoensis and C.ulmeri. Records of the genus from Costa Rica and Tobago represent significant extensions of the known range for the genus, previously unknown north of Panama. A key to males and known females and a species-level phylogenetic analysis are included.     

Description of a new species of Wormaldia from Sardinia and a new Drusus species from the Western Balkans (Trichoptera,Philopotamidae, Limnephilidae)

New species are described in the genera Wormaldia (Trichoptera, Philopotamidae) and Drusus (Trichoptera, Limnephilidae, Drusinae). Additionally, the larva of the new species Drusus crenophylax sp. n. is described, and a key provided to larval Drusus species of the bosnicus-group, in which the new species belongs. Observations on the threats to regional freshwater biodiversity and caddisfly endemism are discussed.The new species Wormaldia sarda sp. n. is an endemic of the Tyrrhenian island of Sardinia and differs most conspicuously from its congeners in the shape of segment X, which is trilobate in lateral view. The new species Drusus crenophylax sp. n. is a micro-endemic of the Western Balkans, and increases the endemism rate of Balkan Drusinae to 79% of 39 species. Compared to other Western Balkan Drusus, males of the new species are morphologically most similar to Drusus discophorus Radovanovic and Drusus vernonensis Malicky, but differ in the shape of superior and intermediate appendages. The females of Drusus crenophylax sp. n. are most similar to those of Drusus vernonensis, but differ distinctly in the outline of segment X. Larvae of Drusus crenophylax sp. n. exhibit toothless mandibles, indicating a scraping grazing-feeding ecology.

Systematics of Tillandsia subgenus Pseudalcantarea (Bromeliaceae)

Tillandsia subg.Pseudalcantarea (Bromeliaceae) includes four species as currently delimited. The phylogenetic relationships of the species in this group are investigated by a cladistic analysis using 16 morphological characters, withVriesea subg.Alcantarea employed as the outgroup.Tillandsia subg.Pseudalcantarea is found to be paraphyletic.Tillandsia grandis andT. paniculata are transferred toTillandsia subg.Tillandsia because they are hypothesized to share a more recent common ancestor withT. utriculata, the type of the genus, than they do with the other two species placed in subg.Pseudalcantarea, i.e.,T. baliophylla andT. viridiflora. These latter two species possibly constitute a basal clade withinTillandsia and are provisionally retained within subg.Pseudalcantarea.     

First report of the genus Kisaura Ross (Trichoptera, Philopotamidae) from India with the description of six new species

The genus Kisaura Ross, 1956 (Trichoptera, Philopotamidae, Philopotaminae) is reported from India the first time. Six new species are described and illustrated: Kisaura elongatasp. n., Kisaura eloctsp. n., Kisaura clavatasp. n., Kisaura gangtokensissp. n., Kisaura truncatasp. n., all from Gangtok (Sikkim) and Kisaura himachalicasp. n. from Barot (Himachal Pradesh). Male genitalia of this genus are distinguishable from those of other genera of the family by the pair of long lateral processes of tergum X, the well-developed mesoventral plates between two segments of the inferior appendages, and by the brush-like row of dark setae on the inner surfaces of the terminal segments (harpago) of the inferior appendages.     

Comparison of sensory structures on the antenna of different species of Philopotamidae (Insecta: Trichoptera)

Structure and distribution of sensilla were studied in sixteen species of the caddisfly family Philopotamidae. Their antennae bear numerous curved trichoid and pseudoplacoid sensilla and fewer coronal, styloconic and chaetoid sensilla on the flagellar segments. The most numerous pseudoplacoid sensilla have non-specific localization. The curved trichoid sensilla form clusters ventrally on each antennal segment. Sensilla belonging to coronal, styloconic and chaetoid types have specific positions. Long grooved trichoid sensilla are located nonspecifically in all the studied species. The average number of sensilla per segment decreases from the proximal to distal part of the flagellum. Scapus and pedicellum are devoid of most types of sensilla, however, they bear the Böhm bristles and long trichoid sensilla. A positive correlation between antenna dimensions and its cuticular structures is found.

Andinopanurgus, a new Andean subgenus of Protandrena (Hymenoptera, Andrenidae)

A new subgenus of Protandrena Cockerell (Panurginae: Protandrenini) from South America, Andinopanurgus Gonzalez & Engel, subgen. n., is described and figured for distinctive species of the genus occurring at mid- and high elevations in the Andes from Venezuela to Peru (1100-3400 m). In addition to the distribution, the subgenus is easily distinguished from other subgenera by a unique combination of morphological characters in both sexes, especially in the hidden sterna and genitalia of the male. Protandrena amyaesp. n., and Protandrena femoralissp. n., are also described and figured from the Ecuadorian and Peruvian Andes. New geographical records and a key to the species are also provided.
