Entomobrya fimbaensis new species

( Figs 7 and 22 )

Type-locality: SPAIN (Barranquillas, Madrid). Sample obtained by Malaise Trap in a plantation of timber trees, in a Mediterranean forest of Quercus ilex var. ballota ("dehesa": traditional Spanish land-use system in which wood collection, raising livestock and agriculture are carried out in a single area).

Type-specimens: Holotype (female), slide labelled MZNA-FIMBA20020924. UTM Co-ordinates (30TVK): X 406210, Y 4473183 E, Z 523. Date: 24/ix/2002. R. Jordana and E. Baquero leg.; 4 paratypes in ethyl alcohol with the same code.

Other material: 3 and 5 specimens in ethyl alcohol respectively coded MZNA-FIMBA20020625 and MZNA-FIMBA20020507.

Material deposited: MZNA.

Description. Body length up to 1.6 mm excluding antennae. Colour pattern as in Fig. 7 , with 5 interrupted longitudinal stripes on thoracic tergite II and abdominal tergite IV; a posterior dorsal patch in the form of an arc on abdominal IV tergite. Eight eyes, GH<EF. Antennae moderate long, 2.45 times the length of the head, with bilobed apical vesicle. Head trichobothrium present. Labral setae formula 5, 5, 4, as in other Entomobrya species. Labral papillae wrinkled with very minute projections. Thoracic tergite II with ’mane’ of macrochaetae. Tibiotarsus with no differentiated setae (except for the smooth terminal setae on legs III, characteristic of the genus). Unguis with four internal teeth: a first pair at 50% from the base of unguis, and two unpaired teeth (the first at 7/10ths the second at three quarters of distance from base), dorsal basal tooth, not beyond half the distance from base of unguis; lateral teeth at 3/5ths distance from unguis base. Manubrial plate with 4 setae and two pseudopores. Mucro with both teeth similar in size, and mucronal spine. Thirty nine relevant characters listed in Table 1. Simplified formula: 3-1-0-2-2/2-3/2-3/1-2-2/0-1 0 5-3-2-2 (Table 1).

Remarks. Entomobrya fimbaensis n. sp. has labral papillae with minute projections, whilst the other species considered in this work have smooth labral papillae. Entomobrya fimbaensis n. sp. has the unguis dorsal tooth near to half the distance from unguis base, as in E. maroccana n. sp., whilst the other species have the unguis dorsal tooth not beyond a third of distance from unguis. Entomobrya fimbaensis n. sp. has 3 setae on m3 series on abdominal II ( Ch. 19), again as E. maroccana n. sp., whilst the other species have 2 setae in this position. Entomobrya fimbaensis n. sp. differs from all other species by the presence of 2 m 3-m4 setae on abdominal III ( Ch. 22), and an unpaired seta on abdominal IV ( Ch. 24). These five differences justify the description of these specimens as a new species.

Etymology. The specific name is derived from the code name of the project during which the specimens were captured (FIMBA).
