Anomaloppia mazandaranica sp. n.

( Figs. 1-4 )

Description

Measurments. Body length 275-310 μm, width 142-160 μm (n=9).

Prodorsum. Rostrum rounded at tip. Rostral setae (ro) situated close to each other, barbed. Lamellar (le) and interlamellar (in) setae thin, setiform, finely barbed and nearly as long as rostral setae. Lamellar line poorly developed, not reaching to the insertion of lamellar seta. Exobothridial setae (ex) moderately long and finely barbed. Sensillus (ss) long, fusiform-clavate; its head with 6 or 7 long barbs sparsely placed and with some short barbs on the stalk. Bothridia round with small opening. Three pairs of muscle sigillae situated between interlamellar setae, and several anterior to each bothridium.

Notogaster. Notogaster oval, broadly rounded anteriorly, but narrowed posteriorly. Ten pairs of notogastral setae, finely barbed; setae lm and la nearly situated in same level. Lyrifissures ia, im and latero-opisthosomal gland (gla) opening well developed.

Ventral region. Epimeral region with a few muscle sigillae. Apodemes I, II, Sj and IV well developed. Epimeral setae mostly short and smooth, only 3c and 4c distinctly barbed; epimeral setal formula (I-IV) 3-1-3-3. Discidium (dis.) well developed, acute. Genital plates with 5 pairs of setae, 3 on anterior half and 2 on posterior half, 1 pair of aggenital, 2 pairs of anal and 3 pairs of adanal setae. Ano-genital region smooth, with few small sigillae situated posterolaterad of each epimeral seta 4b; iad fissures paraanal, adjacent to anal plates.

Legs. Formula of leg setation (trochanter to tarsus): I (1-5-2+1-4+2-20+2); IV (1-2-2-3+1-10). Structure and setation of legs I and IV as shown in Figures 3 and 4 .

Akrami leg., one from Chaloos road (185 km N from Tehran), Mazandaran province, Iran, soil, 36º30´N, 51º2´E, 21m under sea level, 10-IV-2004, M. A. Akrami leg., one from Babol road to Ghaemshahr (5 km SE from Babol), Mazandaran province, Iran, soil, 36º54´N, 52º67´E, 1m above sea level, 3-VI-2004, M. A. Akrami leg. The holotype and five paratypes are deposited in the Department of Plant Protection, Shiraz University, Iran and the rest are deposited in the Department of Plant Protection, Tehran University, Iran.

Remarks

The genus Anomaloppia now includes nine species of semicosmopolitan distribution ( Subias, 2004). Three of them have rostral setae straight, divergent and with their insertions close together: Anomaloppia differens Mahunka & Topercer, 1983 from centromeridional Europe, Anomaloppia ozkani Ayyildiz, 1989 from Turkey and Anomaloppia iranica Bayartogtokh & Akrami, 2000 from Iran. Though they resemble the new species, A. ozkani and A. iranica (which are very similar to each other) are distinguishable from Anomaloppia mazandaranica sp. n. by: 1) sensillus moderately long, more fusiform and with 11 or 12 barbs close to each other; 2) interlamellar seta shorter than lamellar seta and both smooth; 3) notogastral setae shorter and also smooth; 4) seta lm slightly shorter than others; 5) solenidion on genu I half as long as that in new species. A. mazandaranica sp. n. also resembles to A. differens because of the fine barbulation of notogastral setae, but differs from A. differens by its sensillus that is more clavate and its head with fewer barbs, longer and more sparsely placed.
