Variable Selection and Inference for Multi-period Forecasting Problems Author Timmermann, Kim Author Kuhlmann, Michael text Zootaxa 2009 2009-05-11 2099 1 188 http://dx.doi.org/10.17863/cam.5647 journal article 10.17863/cam.5647 1175­5334 5311462 Patellapis (Patellapis) depressa sp. n. Timmermann ( Figs. 3a–g ; 4a–h ) Diagnosis. The females of this species differ from those of P. rubricata in having a medi–longitudial clypeal depression. Further, the inner hind tibial spurs of P. rubricata are more coarsely serrate than in P. depressa . The most similar species is P. gessorum . The females of both species can be distinguished by the colour of the metasomal terga and the structure and size of the supraclypeal area. The females of P. depressa have blackish to pallid brownish metasomal terga (extensively reddish in P. gessorum ) and a broad supraclypeal area (smaller in P. gessorum ). The males of P. depressa can be easily distinguished from those of P. rubricata by the size and structure of the gonostylus and the antennal flagellomeres A3 and A4. The gonostylus of P. depressa is simple (large lateral projection in P. rubricata ) and A4 is about twice as long as A3 (A4 as long as A 3 in P. rubricata ). Both sexes of P. bifurcata differ markedly from P. depressa in their shorter body length. Description Female . Bl = 6,5–7,1mm . General habitus ( Fig. 3e ). Head . L = 1,7–1,8mm ; W = 2,0– 2,2mm .
