No full textParaparatrechina brunnella LaPolla and Cheng, sp. nov. (Fig. 3, 16, 17) Holotype worker, CAMEROON: Nkoemvon; 1980; F 49 (D. Jackson) (BMNH); 8 paratype workers, same locality as holotype (BMNH, NMNH). Worker diagnosis: small size (TL 1.2–1.6); head, mesosoma, and gaster brown, contrasting with yellowishbrown antennae and mandibles; golden pubescence covering body (especially visible on head). Compare with: P. albipes WORKER. Measurements (n= 10): TL: 1.23–1.58; HW: 0.32–0.37; HL: 0.37–0.41; EL: 0.09–0.12; SL: 0.35–0.46; PW: 0.22–0.29; WL: 0.35–0.52; PDH: 0.19–0.25; PrFL: 0.29–0.37; PrFW: 0.1–0.12; GL: 0.45– 0.65. Indices: CI: 81–94; REL: 23–28; SI: 102–124; FI: 30–38 Head brown, with contrasting yellowish-brown antennae and mandibles; cuticular surface shining; head slightly longer than broad. Golden pubescence covers head. Scapes surpass posterior margin by about the length of the first funicular segment. Mesosoma brown and compact; fine golden pubescence covers entire dorsum of mesosoma. Pronotum rises steeply from anterior margin to dorsum. Propodeum low, with a very short, angular dorsal face followed by a long declivitous face; petiole yellowish-brown. Procoxae brown; meso/metacoxae whitish-yellow; trochanters white; femurs and tarsi yellowish-brown, becoming lighter towards last tarsal segments; gaster brown. Etymology. The species epithet is a Latin diminutive adjective meaning brown and small, in reference to the main color of the body and the generally small size of ants in this genus. Non-type material examined: CAMEROON: Nkoemvon, 1980 (D. Jackson); GABON: Prov. Ogooue- Maritime, Reserve de la Moukalaba-Dougoua, 7km NW Doussala, 10 ° 32.65 ’ E, 2 19.84 ’ S, 21.iii. 2000, elev. 110 m (S. van Noort); GHANA: Tafo (B. Bolton); KENYA: Kakamega Forest, E 34 ° 52 ’ 16, N 00° 19.49 (H. Garcia). Notes. P. albipes could be confused with this species if the pro/mesonotal white patch is not distinct on P. albipes. P. brunnella possess more pubescence on the head and mesosoma than P. albipes, and has a shorter scape (brunnella range: 0.35–0.46 mm compared with albipes range: 0.48–0.53 mm).Published as part of Lapolla, John S., Cheng, Chiu H. & Fisher, Brian L., 2010, Taxonomic revision of the ant (Hymenoptera: Formicidae) genus Paraparatrechina in the Afrotropical and Malagasy Regions, pp. 1-27 in Zootaxa 2387 on pages 7-8, DOI: 10.5281/zenodo.19380

Imagism reconsidered, with special reference to the early poetry of H. D.
Full text linkThe main aim of this thesis is to examine how H. D. developed her poetics during the Imagist movement by looking especially at her work in the Imagist anthologies (1915-1917). In order to identify the distinctive qualities of H. D.'s poetry, I shall compare it with that of other Imagists, notably Richard Aldington, John Gould Fletcher, F. S. Flint and Amy Lowell. Previous discussions of H. D.'s early poetics have been held within the context of Ezra Pound's aesthetics, and the characteristics of her poems which are inconsistent with Pound’s criteria have been ignored. Hence, one of the most useful strategies to reinterpret H. D.'s poetry is, first and foremost to reconsider Pound's Imagist theory from a different viewpoint. Because of this, in the first half of this thesis, I will consider Imagism in respect of Japanese poetics; for as regards the relationship between Pound’s theory and the haiku and the Chinese ideograph, there are some important issues which have been hardly discussed. So, these issues provide room for reconsidering the formation of Imagism. Since H. D. left behind hardly any literary criticism, her poems are the most useful source from which to draw clarification of her poetic criteria. Moreover, her correspondence with Amy Lowell provides significant evidence for an examination of H. D.'s poetic practice at this time. In the second half of the thesis, by quoting her own words in letters to Lowell, I identify the characteristics of H.D.'s Imagism which obviously differ from Pound's theory, and trace her development within the Imagist period. By raising a number of critical issues, I intend to illuminate the diversity of Imagism
Paraparatrechina umbranatis LaPolla and Cheng, sp. nov.
No full textParaparatrechina umbranatis LaPolla and Cheng, sp. nov. (Fig. 9, 16, 17) Holotype worker, GABON: Prov. Ogooue-Martime; Res. Monts Doudou; 24.5 km 303 ° WNW Doussala; 2 °14.0’S, 10 ° 23.9 ’E; 18.iii. 2000; elev. 630 m (B.L. Fisher # 2276) (CASC); 8 paratype workers, same locality as holotype (CASC, USNM) Worker diagnosis: body distinctly bicolored, with gaster much darker than head and mesosoma. Compare with: P. oreias and P. subtilis WORKER. Measurements (n= 12): TL: 1.19–1.57; HW: 0.34–0.36; HL: 0.38–0.41; EL: 0.098–0.112; SL: 0.38–0.43; PW: 0.21–0.27; WL: 0.42–0.49; PDH: 0.18–0.23; PrFL: 0.31–0.34; PrFW: 0.098–0.112; GL: 0.39–0.7. Indices: CI: 87–92; REL: 25–29; SI: 108–120; FI: 30–36 Head yellowish-brown to light brown, with antennae mandibles, and medial area between antennae slightly lighter; head slightly longer than broad. A dense layer of fine, short, slightly decumbent pubescence covers head. Scapes surpass posterior margin by about the length of the first funicular segment; scape with a dense, slightly decumbent pubescence. Mesosoma yellowish-brown to light brown; fine pubescence covers entire mesosomal dorsum; lateral portions of the mesosoma are distinctly shinier than the dorsum. Pronotum rises steeply from anterior margin to dorsum. Propodeum possesses a short, angular dorsal face, with a long declivitous face. Legs generally lighter colored than mesosoma, becoming whitish towards last tarsal segments. Procoxae usually darker brown than meso/metacoxae; gaster conspicuously darker than head and mesosoma and is covered in a dense layer of pubescence. Etymology. The species epithet is a Latin noun in apposition, a compound of umbra (=shade) and natis (=rump), in reference to the fact that the gaster is much darker in color than the head and mesosoma. Non-type material examined: ANGOLA: Salazar, 9–15.iii. 1972 (P.M. Hammond); GABON: Prov. Ogooue-Maritime, Res.

Snelling & A. Espira). Notes. This species is easily recognizable by the distinctly darker gaster (brown) contrasting with the yellow-brown head and mesosoma. While many Paraparatrechina species display various coloration patterns between the different tagmata this is the only species that could be considered truly bicolored.Published as part of Lapolla, John S., Cheng, Chiu H. & Fisher, Brian L., 2010, Taxonomic revision of the ant (Hymenoptera: Formicidae) genus Paraparatrechina in the Afrotropical and Malagasy Regions, pp. 1-27 in Zootaxa 2387 on pages 15-16, DOI: 10.5281/zenodo.19380

Belshaw) (BMNH); 6 paratype workers, same locality as holotype (BMNH, USNM). Worker diagnosis: Small size (TL: 1.2–1.44); HL & SL <0.4 mm. Compare with: P. oreias and subtilis WORKER. Measurements (n= 12): TL: 1.2–1.44; HW: 0.32–0.34; HL: 0.36–0.38; EL: 0.084–0.098; SL: 0.34–0.38; PW: 0.22–0.25; WL: 0.36–0.42; PDH: 0.19–0.21; PrFL: 0.28–0.30; PrFW: 0.09–0.11; GL: 0.47– 0.67. Indices: CI: 85–94; REL: 24–26; SI: 102–115; FI: 32–36 Head brownish-yellow, with lighter yellow colored clypeus, mandibles, and antennae and area around torulae. A fine, short pubescence covers the head. Scapes surpass posterior margin by about the length of the first 2 funicular segments. Mesosoma compact, laterally brownish-yellow, with dorsum lighter yellow, and a fine pubescence covering the entire mesosomal dorsum. Pronotum rises very steeply from anterior margin to dorsum; propodeum possesses a short, angular dorsal face, with a long declivitous face. Procoxae typically brownish-yellow as in mesosoma, although procoxae in some specimens are lighter yellow; overall, the legs are brownish-yellow, becoming yellow towards last tarsal segments; gaster brownish-yellow becoming lighter yellow around segmental margins. Etymology. The species epithet is a Latin noun in apposition for dwarf, in reference to the fact that this is the smallest species of Paraparatrechina currently known from the Afrotropics. Non-type material examined: GHANA: Enchi, 23.v. 1969 (D. Leston); Enchi, 27.v. 1969 (D. Leston); Enchi, 28.v. 1969 (D. Leston); Mankrang For., Res. Nr. Akomadan, 11.iii. 1992 (Belshaw); NIGERIA: Onipe, 25.vii. 1975 Notes. This species is most likely to be confused with P. oreias, but can separated by its overall smaller size in head width and length and scape length. P. gnoma is currently the smallest known Afrotropical Paraparatrechina species, although P. brunnella is very small as well (TL: 1.23–1.58).Published as part of Lapolla, John S., Cheng, Chiu H. & Fisher, Brian L., 2010, Taxonomic revision of the ant (Hymenoptera: Formicidae) genus Paraparatrechina in the Afrotropical and Malagasy Regions, pp. 1-27 in Zootaxa 2387 on pages 10-11, DOI: 10.5281/zenodo.19380
