The first Colombian records are given for A. bari Stark, A. curiosa Stark and A. harperi Stark; the latter two species were previously known from Mesoamerica and this is their first report from South America. New records, mainly in the Andinum natural region, are presented for 20 previously reported Colombian species. In addition, the unknown females of A. calima Baena & Rojas, A. marta Zúñiga & Stark and A. yameo Stark & Sivec are described, and three unassociated females are described under informal designation. Keywords: Stoneflies, Plecoptera, Anacroneuria, Colombia INTRODUCTION Recent studies of Anacroneuria have documented the presence of 51 species of this diverse genus in Colombia (Stark et al. 1999; Stark & Zúñiga 2003; Zúñiga & Stark 2002; Zúñiga et al. 2006). Although most of these species are still known only for Colombia, increasingly records are added which indicate some faunal overlap occurs with neighboring countries. The present collections, mainly from protected areas in Risaralda in the central Andes of Colombia, include the first records of three species previously known from Venezuela (A. bari Stark) or Mesoamerica (A. curiosa Stark and A. harperi Stark), but also include seven species new for science and additional records for 20 species previously reported for Colombia. Holotype specimens are deposited in the Museo de Entomología, Universidad del Valle, Cali, Colombia (MEUV), or in the Museo de Entomología “Francisco Luis Gallego”, Universidad Nacional, Medellín, Colombia (MEFLG), as indicated in the text. Duplicate paratypes and other specimens are deposited in the following collections: the Museo de Historia Natural, Colección de Entomología, Instituto de Ciencias Naturales-Universidad Nacional, Santafé Illiesia - http://www2.pms-lj.si/illiesia/ Volume 3 – Number 13 – Page 127 Zúñiga, M. del C., B.P.

Additions to the Colombian Anacroneuria fauna (Plecoptera: Perlidae) with descriptions of seven new species. Illiesia, 3(13):127-149. Available online: http://www2.pms-lj.si/illiesia/Illiesia03-13.pdf Adult habitus. General color yellow brown patterned with brown. Head mostly yellow but dusky over ocelli; lappets brown (Fig. 1). Pronotum with wide, pale mesal band and darker lateral bands, but pattern obscured by specimen condition. Wings pale amber, veins dark amber with darker R veins. Legs pale except narrow, apical band on femora dark. Male. Forewing length 13 mm. Hammer thimble shaped, height greater than basal diameter (Fig. 2). Aedeagal base damaged, but intact apex, in lateral aspect, sharply upturned at a 90" angle and bearing small basal and larger mesal ear shaped lobes (Fig. 4). Apex in ventral aspect with large ear lobes extending forward giving the apex a trilobed appearance; basal lobes give the shoulders a slight bulging projection (Fig. 3). Dorsal aspect with prominent transverse keel connecting to smaller, ventrally directed triangular keel on meson; basal ear lobes form a pair of small shelf-like projections (Fig. 5). Right hook and base of aedeagus are broken but are stored in the abdominal tip of the specimen. Female. Unknown. Larva. Unknown. Etymology. The species name, used as a noun in apposition, is based on the type locality in Farallones de Citará. Diagnosis. This species is similar to A. albimacula Klapálek and A. rugosa Stark in general aedeagal structure (Stark et al. 1999; Stark 2001). The former species has a distinctive clear “window” at the cord in the wing pigment pattern and the aedeagus lacks the smaller, basal ear lobes, whereas the latter species has the lateral ear lobes projecting beyond the mesoapical lobe (see Fig. 99 in Stark 2001). Ecological notes. The type locality in northwest Colombia is part of Región Natural Andina on the east slope of Cordillera Occidental. Anacroneuria otun sp. nov., Stark & Zúñiga (Figs. 6-10) Material examined.

Zúñiga, W. Cardona, G. Zabala, Cardozo- Zúñiga (Holotype and 2 paratypes: MEUV, paratype: BPS). Adult habitus. General color dark brown patterned with yellow. Head covered mostly with dark brown but M-line with three prominent pale areas; occiput dusky brown except for pale post- ocellar area. Pr o no t u m b r o wn with n arrow me dian pal e band an d scattered dark rugosities (Fig. 6). Wing membrane transparent, veins dark brown. Legs brown, tibia darker than femora, except narrow, dark, apical femoral band. Male. Forewing length 18 mm. Hammer cylindrical, height greater than diameter (Fig. 7). Aedeagal apex short, slightly longer than wide, and rounded; venter with a pair of small membranous lobes, shoulders broad (Fig 8). Dorsal keel steep, composed of a pair of narrow ridges which end slightly beyond mid length of apical area (Fig. 10). Membranous areas dorsad and basal to hooks bulging. Lateral aspect of apex about as wide as long (Fig 9). Female. Unknown. Larva. Unknown. Etymology. The species name, used as a noun in apposition, is based on Río Otún, the type locality. Diagnosis. The aedeagus of this species is most similar to that of A. cajas Zúñiga & Vimos, a recently described Ecuadorian species (Zúñiga et al. 2006). The aedeagal apex of A. cajas is more pointed and the dorsal keel is significantly weaker than in A. otun. In addition, the pronotum of A. cajas has dark pigment adjacent to the median suture, whereas in A. otun a narrow, median pale band occurs. Ecological notes. The type locality is in the headwaters of Rio Otún in the highest mountains of the Cordillera Central and is part of Región Natural Andina de Colombia. This small second order stream is about 8 m wide and 0.4-0.5 m deep, with a mixed substrate composed of boulders, stones, patches of gravel and sands, and riffle zones primarily. The water quality is in optimum environmental condition, the temperature was 10°C and the air, 12°C at the time of collection. Natural riparian vegetation is present, the zone receives 1900 mm mean annual rainfall and is covered by a very humid montane forest, in accordance with Holdridge life zones system (Espinal & Montenegro 1963). These specimens were collected during the dry season.

The species appears to be relatively common over a broad range of the Cordillera Occidental and Cordillera Central, but these specimens represent the third report from Risaralda, mainly in protected areas and at the highest altitudes known in the mountains of the Los Nevados National Park.

Discussion. This species was previously reported from this same locality by Züniga et al. (2006) but the female specimen, collected at the same time, had not previously been studied. This specimen matches the color pattern of the holotype closely and is an almost certain match. The locality is in the lowlands of Río Amazonas central basin in the small Colombian “trapezium” between Peru and Brasil. The water of the creek is slightly colored, the water temperature at the time of collection was 24°C and natural riparian vegetation is present. Female. Forewing length 11.5 mm.

This series of specimens, collected by light traps at several localities, and on separate dates, from Risaralda in the Región Natural Andina, includes a large number of females (112), but no male was associated with them. This situation suggests that the male of this species may not be strongly attracted to the black or white light. 47 48 49 Figs. 47-49. Anacroneuria CO-9. 47. Head and pronotum, 48.

Available online: http://www2.pms-lj.si/illiesia/Illiesia03-13.pdf Discussion. The Brazilian specimen shares the leg and pronotal patterns but has a slightly different head pattern. The subgenital plates also differ slightly but the setal patterns of sternum 9 are very similar. The collection locality belongs to the Región Natural Amazónica in lowlands of Río Amazonas central basin. The water of the small streams is slightly colored by soluble organic compounds such as tannins and lignins from the flooded forest in this area. Water temperature at the time of collection was 23°C and the air 26°C. ACKNOWLEDGMENTS The field trips in the Central Andes of Risaralda had the partial economic support of John D. and Catherine T. MacArthur Foundation; Colombian Program of Wildlife Conservation Society-WCS and Fundación EcoAndina-Cali, Colombia, gave logistic support; we specially thank G. Kattan.
