Bonner zoologische Beitr?ge Band 52 (2004) Heft 1/2 Seiten 121-125 Bonn, August 2004 Notes on Neotropical Alticinae (Cole?ptera, Chrysomelidae) Lev N. Medvedev Severtsov Inst. Ecol. & Evolution, Russian Academy of Sciences, Moscow Abstract: A list of Alticinae from Hispaniola is given with descriptions of one new genus and six new species, as well as one new species from Brasilia. Key words: South America, flea beetles, taxonomy, biogeography, new taxa. 1. INTRODUCTION The article proposed is based mostly on material collec- ted by J. & S. Klapperich on the island of Hispaniola and deposited in the Basel Museum of Natural History; as well as one new species from Brasilia was found in the Stuttgart Natural History Museum. The following abbreviations for depository locations are used: NHMB Naturhistorisches Museum, Basel SMNS -Staatliches Museum fuer Naturkunde, Stuttgart LM -author's collection. 2. TAXONOMY 2.1. Island of Hispaniola Hirtasphaera Medvedev, gen. n.-(Fig. 1) Description. Body elongate, distinctly flattened above. Head impunctate, frontal tubercles subquadrate, interan- tennal ridge high, frons narrow, as wide as eye, clypeus elevated posteriorly, vertex with longitudinal impressed line, eyes round. Antennae filiform, reaching middle of elytra. Prothora.x transverse quadrangular, much narro- wer than elytra at base, all angles distinct, with setife- rous pore, but not produced (Fig. 1), surface without transverse basal groove. Elytra elongate, impunctate, without basal convexity, with dense erect hairs. E- pipleurae broad, horizontal, in lateral view seem only in anterior third. Presternum flat, narrowed in middle. Me- sosternum with hind margin arcuately emarginate. Me- tasternum neither marg?nate nor elevate anteriorly. Last abdominal sternite of male with dark longitudinal line. Hind femora twice as long as wide, hind tibia 1.5 times as long as width of femur, with small preapical tooth followed with shallow excavation on outer margin. Spur short and thick. Hind tarsus: segment 1 about 2.5 times shorter than tibia, last segment globular on apex. Diagnosis. This new genus is similar to Asphaera Chev- rolat, 1842, but it differs well in pubescent elytra, not produced anterior angles of rather narrow prothorax and globular apex of last segment on hind tarsi. In any case, I don't know any species or genus in Oedionychini with pubescence on the elytra. Type species: Hirtasphaera hirsuta, sp. n. Hirtasphaera hirsuta L. Medvedev, sp. n. (Figs 2, 3) Holotype (male): Dominican Republic, Constanza, 1250 m, 10. V. 1972, leg. J. & S. Klapperich (NHMB). Paratypes: same locality, 1 male (LM), 1 female (NHMB). Description: Pale flavous: antennal segments 7-9, api- cal part of segment 6 and scutellum black, elytra with 5 dark metallic spots (2, 2, 1; Fig. 2) and narrow dark e- margination around scutellum. Head feebly shining, frontal tubercles with dense mic- rosculpture. Proportions of antennal segments: 11-4-7- 8-10-10-10-8-8-8-11. Prothorax 2.1 times as wide as long, anterior margin practically straight, lateral margins straight, subparallel, broadly expl?nate; surface impunc- tate, shining. Elytra 1.5 times as long as wide. Aedeagus -fig. 3. Length 6.4 mm, width 3.3 mm. Homophaeta albicollis (Fabricius, 1787) Material: Dominican Republic, Colonia, 1000 m, 18. III. 1972; leg. J. & S. Klapperich, 1 ex.; -Constanza. 7.VII. 1972, leg. J. & S. Klapperich, 1 ex. (NHMB). General distribution: South America and West Indies, including Haiti and Dominican Republic (BLAKE 1931).
