Danowhetaksa Simonsen, Ware & Archibald 2022, new genus
No full textDanowhetaksa Simonsen, Ware & Archibald, new genus Diagnosis. Most easily distinguished from Whetwhetaksa by: 1, pterostigma length ca. 7 times width [ca. 10 times]; 2, dark fascia mid-wing, basal wing hyaline [colouration extends to wing base where known]; 3, origin of IR2 closer to nodus than to origin of R3-4 [closer to origin of R3-4], at least three crossveins between them [one]; 4, MP, CuA more widely separated distally [maximum ca. 10 cells at margin], not subparallel [maximum two cells, subparallel]. Type and included species. Type species, Danowhetaksa birgitteae n. sp. here designated; other included species, Danowhetaksa rusti n. sp. Etymology. The genus name is formed from the prefix ‘Dano-’ referring to Denmark, and the suffix ‘-whetaksa’ referring to the Whetwhetaksidae. Gender: feminine.Published as part of Simonsen, Thomas J., Archibald, S. Bruce, Rasmussen, Jan A., Sylvestersen, René L., Olsen, Kent & Ware, Jessica L., 2022, Danowhetaksa gen. nov. with two species from the early Eocene Ølst Formation from Denmark, the first Palearctic Whetwhetaksidae (Odonata: Cephalozygoptera), pp. 586-592 in Zootaxa 5099 (5) on pages 587-588, DOI: 10.11646/zootaxa.5099.5.5, http://zenodo.org/record/611028
Bia decaerulea subsp. cayana Simonsen & Penz, NEW SSP.
No full textBia decaerulea cayana Simonsen & Penz, NEW SSP. (Figs 4 c–f, 10e, 12) Diagnostic description. Defined by the following combination of characters: (1) MF DFW white apical ocelli medium-large. (2) MF DFW orange band somewhat diffuse, in M very wide and often extended into the discal cell (fading proximally); orange scales broadly extended proximally along veins, lining cross-veins at the distal edge of discal cell. (3) M DFW iridescent band absent; a glistening sheen is visible across the entire forewing. F DFW blue iridescence well developed but variable; usually extended across the entire DC, diffuse anteriorly; usually visible at the CuA1-CuA2 intersection; below the discal cell, the iridescent area is wide and may spread towards the tornus to meet the edge of the orange band, being similar to that of actorion but wider than in decaerulea decaerulea. (4) M DFW androconial scales on the CuA-CuA1-CuA2 intersection dark brown, matching scale color of surrounding area and intermingled with orange scales. (5) M DHW discal androconial pad dark brown, nearly black, always darker than associated hairpencil. (6) M DHW discal hairpencil dark brown, but lighter in color than discal androconial pad. (7) F VFW ripple pattern less dense than that of M, with the VFW postmedial area showing a more predominantly yellow color and with one or two pale markings sometimes present across DC. Etymology. The name cayana refers to the locality Cayenne in French Guiana. Type material.

Bia rebeli subsp. aegina Penz & Simonsen, NEW SSP.
No full textBia rebeli aegina Penz & Simonsen, NEW SSP. (Figs 5 c–f, 10g, 12) Diagnostic description. Defined by the following combination of characters: (1) MF DFW white apical ocelli medium-small (most of the range) showing a cline to very small or absent (the DFW and VFW apical ocelli, and the VFW ocellus below M1 are very small or absent in Bolivian specimens). (2) M DFW orange band moderately wide, usually opaque; orange scales somewhat extended proximally along veins. (3) M DFW iridescent band from anal margin to approximately half of the CuA2 cell in most specimens, nearly reaching CuA 2 in others, and less frequently reaching CuA2 (southern Peru; variable within localities). F DFW iridescent band more diffuse and narrower than that of actorion, especially noticeable below CuA2 where the iridescence is less extended towards the tornus. (4) M DFW androconial organ on the CuA-CuA1-CuA2 intersection pale, contrasting scale color of surrounding area. (5) M DHW discal androconial pad varying from pale brown to silvery brown. (6) DHW discal hairpencil brown, darker in color than discal androconial pad. (7) F VFW ripple pattern less dense than that of M. Etymology. In Greek mythology, Aegina, daughter of the river god Asopus, married Actor, son of king Deioneus of Phocis and his wife Diomede. Here we name one of the Bia rebeli subspecies after the nymph Aegina as means of acknowledging that this species is separate from Bia actorion. Type material.

DeVries Trap: 4 und // HOLOTYPE Bia rebeli aegina Penz & Simonsen, 2017. Paratypes are listed in Appendix, and Fig. 5 d shows a paratype F. Distribution and examined specimens. Fig. 12 and Appendix. Remarks. Specimens from Bolivia slightly differ from Peruvian by their minute (sometimes absent) dorsal forewing white apical ocelli, and a very small dark ocellus in ventral forewing cell M2 (compare Figs 5 e–f with 5c– d). Although examined specimens from Peru, Manu National Park generally conform to the rebeli aegina phenotype, one specimen has paler than expected hind wing discal androconial organs (Fig. 5 g) although not as pale as those of rebeli rebeli or rebeli acreana.Published as part of Penz, Carla M., Casagrande, Mirna M., Devries, Phil & Simonsen, Thomas J., 2017, Documenting diversity in the Amazonian butterfly genus Bia (Lepidoptera, Nymphalidae), pp. 201-237 in Zootaxa 4258 (3) on page 218, DOI: 10.11646/zootaxa.4258.3.1, http://zenodo.org/record/56972
Haplopacha lunata Dupont, Simonsen & Zilli, 2016, sp. nov.
No full textHaplopacha lunata sp. nov. (Fig. 1 I) Type (s): holotype ♂, in NHM. Type locality: District of the Great Craters, Tanganyika Territory. Diagnosis. This species is most easily distinguished by the crescent-shaped discal spot, grey lunulate submarginal spots of forewing and pale-coloured hind wing. Distribution and localities. Only a single specimen from Northern Tanzania. Flight period. February–March. Material examined: Holotype male (Fig. 1 I) (BMNH (E)_ 1377279, NHM London, Tams dry genitalia dissections (1955 / 796) mounted on slide: Lasiocampidae # 1572 (Fig. 6 D)), District of the Great Craters, Tanganyika Territory, Feb.–March 1921, TA. Barnes [leg.]. Description: Forewing triangular, grey-coloured, with pale cinereous tinge in basal and distal fields. ante- and postmedial bands not sharply defined all the way to costa, thus making median field somewhat blurred anteriorly Antemedial line straight and very oblique inferiorly. Submarginal spots darker grey, lunulate. Basal wing spot oval with major axis oriented parallel to the costa. Discal wing spot crescent-shaped, spanning the entire width of open discal cell and lined with white scales along inner margin. Hind wing pale beige-brown. Male genitalia (Fig. 6 D): Vinculum undifferentiated, U-shaped. Cucullus very small and flimsy, finger-like, originating high on vinculum-tegumen ring. Sacculus large, overpassing cucullus by at least a full length of the cucullus itself with stout, distally spatulate saccular process, which is exteriorly ornamented with small spines. Saccular lobes about 1 / 3 of basal width of sacculus, with sparse covering of long setae. Uncus and gnathos missing from the preparation. Phallus broad cylindrical, slightly curved. Vesica as a cylindrical elongation of phallus with single terminal straight cornutus, at least ½ as long as phallus itself. Etymology. The species name lunata refers to the characteristic crescent shape of the discal wing spot.Published as part of Dupont, Steen, Simonsen, Thomas J. & Zilli, Alberto, 2016, Haplopacha (Lepidoptera: Lasiocampidae) reviewed: four new species, first descriptions of the genitalia of both sexes, and unique alar scale organs, pp. 445-457 in Zootaxa 4109 (4) on page 454, DOI: 10.11646/zootaxa.4109.4.3, http://zenodo.org/record/26585
