Pergalumna aequiporosa View in CoL sp. nov.
Diagnosis
All prodorsal setae long. Sensillus setiform, pilose. Dorsosejugal suture absent. Three pairs of porose areas present, Aa located medially. Whole surface distinctly punctate.
Material examined
Holotype Kenya, Muguga , near Nairobi, 20 November 2004. Leg. Cs. Csuzdi (Afr- 978). Seven paratypes from the same sample . Holotype (1700-HO-2005) and five paratypes (1700-PO-2005): HNHM, two paratypes: MHNG .
Measurements
Length of body 706–803 Mm, width of body 484–540 Mm.
Prodorsum
Rostral part wide, conical, without peculiar apex. Lamellar and sublamellar lines clearly visible also in dorsal view. Rostral and lamellar setae finely pilose, setae le longest. Interlamellar setae much thicker than the others and barbed. Sensillus long, filiform, directed laterally and posteriorly, also distinctly barbed. Sejugal porose areas small, round, seem to be fused with structures hy, which are conspicuously large.
Notogaster
Dorsosejugal suture completely absent. Notogaster clearly punctate, pteromorphae striate and also punctate. Three pairs of comparatively large porose areas present, all three pairs characteristically elongated ( Figure 13A View Figure 13 ), anterior pair Aa located medially, far from the pteromorphae. The fused median porose areas (A 1 + A 2) sometimes narrowed posteriorly. Ten pairs of setal alveoli and the glandular opening clearly visible.
Lateral part of podosoma
Lamellar and sublamellar lines run parallel, distance between them small ( Figure 13C View Figure 13 ).
Ventral regions ( Figure 13B View Figure 13 )
Epimeral setal formula: 1-0-1-1. Setae 1b longest. Three pairs of setae arising on the anterior margin of the genital plates, all three nearly equal in length. Aggenital, anal and adanal setae short, simple.
Remarks
The new species belongs to a species group of the genus Pergalumna Grandjean, 1936 , which is well characterized by the filiform sensillus and the three pairs of areae porosae of the notogaster. On the basis of the length of the prodorsal setae and the same size of the porose areas the new species resembles Pergalumna somalica (Berlese, 1916) ; however, the sculpture of the prodorsum and pteromorphae is strong (surface smooth in somalica ), and porose areas Aa located near setae ti, far in somalica .
Etymology
Named after the similar form and size of the notogastral porose areae.
