Penapis larraini Packer, new species
No full textPenapis larraini Packer, new species (Figs. 1, A–J) Diagnosis. The male can be differentiated from other species of the genus by the absence of sublateral processes on S 6 and the form of the sublateral processes on S 5 (Figs. 1 C–F). In side view, the latter have a narrow, digitiform apex, which is dorsoventrally flattened (Fig. 1 E). All other species in the genus have rounded (in P. penai angulate) sublateral processes on S 6 and approximately triangular processes on S 5, which are not dorsoventrally flattened, rather they are uniformly obliquely compressed. The female is most easily distinguished by the punctation of the metasomal terga: T 1 –T 4 have large, shallow punctures on the apical half (excepting the apical impressed areas) and T 2 –T 4 have minute, denser punctures bearing minute setae that are restricted to the anterior half of the tergum (slightly more extensive medially) (Fig. 1 J). Other species have the horizontal portion of T 1 impunctate, or almost so, and the minute punctures of T 2 –T 4 more extensive, at least on T 3 approaching the apical impressed areas medially to a distance much less than the length of the impressed area (Fig. 1 K). The male has similar sculpture but is more readily separated by the sternal characters noted above. Description. Male: Head width 1.85–1.90mm, ITW 1.4–1.45mm, wing length 4.8 –5.0mm, body length 7.4–7.6mm. Lower part of face moderately projecting (Fig. 1 A). Pterostigma with pale disc bordered by brown marginal veins. Midtibial spur gently curved almost to base. S 4 with more than 10 outwardly recurved plumose setae on each side; apical comb pale amber, more than 20 straight setae on each side, narrowly interrupted medially (Fig. 1 B), comb setae finer and longer than in other species. S 5 with median apical process shorter than sublateral process, laterally compressed and somewhat downcurved apically; sublateral process in lateral view with deep basal portion ending in acute angulation ventrobasad of dorsoventrally flattened, narrow apical projection (Figs. 1 C–E). S 6 lacking sublateral process, surface flat, apical concavity broad, truncate (Fig. 1 F). S 8 and genital capsule as in figures 1 G and 1 H. Female: Head width 4.8–5.2mm, ITW 1.42–1.52mm, wing length 4.8–5.2mm, body length 7.3–8.4mm. Midfemur flat over most of anterior surface, somewhat concave towards apex because of apicodorsal swelling. Scopa pale straw. Metasomal terga with sparse, shallow, large punctures on apical half (apical impressed areas excepted); punctures smaller, denser and more distinct on T 5 and T 6; anterior half of T 2 –T 4 with minute punctures separated by> their diameters; minute punctures extending slightly past midlength of tergum medially, less extensive laterally (Fig. 1 J). Material studied. Holotype male: CHILE Region I, Alto Patache, xi. 1997, W. Sielfeld. Allotype female, one male paratype and two female paratypes with identical label data, PUCV with one pair of paratypes at PCYU. Three female paratypes (one missing the head) same locality, 820m, one each from 30.xi.1997, 02.xii. 1997 and 07.xii. 1997, H. Larrain, two at PCYU, one at PUCV. Although not stated on any labels, the locality is at 20 ° 49 ’S; 70 °09’W. Etymology. The species is named after Horacio Larrain, eco-anthropologist and archaeologist of the Universidad Boliviariana in Iquique, northern Chile. The name is appropriate as his wife, Marta, is a sister of the renowned, late Chilean entomologist Luis Peña, after whom the genus and its type species were named. Dr. Larrain collected the first specimens of the species seen by the author and has been involved with numerous research projects on the locus typicus.Published as part of Packer, Laurence, 2012, Penapis larraini Packer, a new species of rophitine bee (Hymenoptera: Halictidae) from a fog oasis in Northern Chile, pp. 54-58 in Zootaxa 3408 on page 55, DOI: 10.5281/zenodo.21437
Geodiscelis (Nazcoediscelis) Packer and Dumesh, new subgenus
No full textGeodiscelis (Nazcoediscelis) Packer and Dumesh, new subgenus urn:lsid:zoobank.org:act:0249B 978 - 22 A 9-4919 - 95 D 9 -A 54 EE 618 DE 33 Type species. Geodiscelis nazcalinea Packer & Dumesh sp. nov. Here designated. Diagnosis. The combination of metasoma with pale subapical transverse bands, maxillary palpus with all 6 palpomeres similarly robust and malar space at least 3 X as long as the basal depth of the mandible is sufficient to identify any colletid bee as belonging to this subgenus. Additionally, the males have S 6 obtusely angulate or with a spine apicomedially. Description. Lower paraocular area black. Male protibia entirely or almost entirely yellow. Metasomal terga with pale subapical integumental bands, basal bands of appressed squamose pubescence present, minute silvery hairs absent. Clypeus and lower paraocular area dull due to imbricate microsculpture. Frontal area with interspaces equal to or greater than puncture diameters. Mesoscutum somewhat shiny, microsculpture imbricate; punctures transversely effaced. Galeal comb teeth absent. Mandible with subapical tooth small to absent. Malar space enormous, at least three time as long as basal depth of mandible. Anterior tentorial pit elongate, almost attaining apex of clypeus. Supraclypeal area mostly flat. Metasternum between metacoxae very narrow, width subequal to MOD. First abscissa of M+Cu of hind wing shorter than 2 nd abscissa. Male hindleg unmodified, narrow; both sexes with two metatibial spurs. Horizontal surface of metapostnotum subequal in length to scutellum. Sclerotized portion of proctiger undivided medially. Male S 6 with apex angulate or spinose. S 7 apicodorsal lobe simple, flat. S 8 apical process narrowing to apex; posterior margin of lateral lobe narrowly concave, posterior convexity laterad. Gonobase with apicoventral rim lacking a median process. Gonoforceps with subapical medial angulation. Gonostylus short, narrow; retrorse lobe broad, rounded. Female sternal scopa well developed. Included species. Geodiscelis longiceps Packer, 2005, G. nazcalinea Packer & Dumesh, sp. nov. and G. phisquiri Packer & Dumesh sp. nov. Etymology. The name is derived from that of the type species, which was first found very near to the famous Nazca lines in Peru, combined with Oediscelis. Comments. This subgenus is known only from west of the peaks of the Andes mountains and occurs from the coastal plains of Peru to moderate altitude on the western slopes of the mountains in Chile. The enormously elongate head is undoubtedly related to the need to obtain nectar from Boraginaceae with deep nectaries. Similarly elongate heads are known in a few species of Xeromelissa where additional mouthpart elongation arises primarily through lengthening of the maxillary palpus. In contrast, the maxillary palpi of Geodiscelis (Nazcoediscelis) are unmodified, as is the case in all xeromelissine genera except Xeromelissa (although they are elongate in some species of Chilicola (Hylaeosoma)); Geodiscelis (Nazcoediscelis) have the cardines, stipites and prementum all extremely elongate. While three subgenera may seem excessive for a genus containing only 5 species at present, the enormous diversity found within these few species would seem to justify recognizing them at this rank. It is perhaps worth noting that there are 170 monotypic subgenera, and almost 100 monotypic genera, among the bees (Ascher & Pickering, 2013). All Geodiscelis species have been found associated with flowers of Heliotropium or Tiquilia, both members of the Boraginaceae. There are numerous species in this group of plants in the region encompassed by known records of Geodiscelis and additional searching among their flowers will undoubtedly result in the discovery of more undescribed bees. Following more exhaustive searches for these interesting little bees and the discovery of more species, a formal biogeographic analysis might be of interest. Currently, the two short headed subgenera are from Argentina whereas species of the long headed subgenus are from west of the Andes.Published as part of Packer, Laurence & Dumesh, Sheila, 2014, Two new species of Geodiscelis Michener & Rozen (Hymenoptera: Apoidea: Colletidae) with a phylogenetic analysis and subgeneric classification of the genus, pp. 275-291 in Zootaxa 3857 (2) on page 288, DOI: 10.11646/zootaxa.3857.2.7, http://zenodo.org/record/22550
