Sunius sexspinosus

sp. n.

Sunius sexspinosus   sp. n. ( Figs 38-48 View Figs 38-47 View Fig , Map 1 View Map 1 )

Type material:

Holotype : TR [20] - Muğla, 15 km ENE Muğla, 1190 m, pasture with stones, 37°14'58N, 28°30'07E, 10.IV.2006, V. Assing GoogleMaps   / Holotypus  Sunius sexspinosus   sp. n. det. V. Assing 2006 (cAss)   . Paratypes: 3 , 6 : same data as holotype (cAss); 2 , 2    : same data, but leg. Wunderle (cWun)   .


Small species, 2.6-3.2 mm (abdomen extended). Habitus as in Fig. 38 View Figs 38-47 . In external morphology highly similar to S. fortespinosus   , but distinguished as follows:

Coloration on average paler: forebody yellowish, elytra of same colour as head and pronotum; paratergites and apex of abdomen reddish to reddish brown. Puncturation of head on average slightly sparser, especially in median dorsal area. Elytra on average slightly shorter and more slender, approximately 0.70 times as long as pronotum ( Fig. 39 View Figs 38-47 ).

: sternite VII not distinctly modified ( Fig. 40 View Figs 38-47 ); sternite VIII unmodified, except for posterior incision ( Fig. 41 View Figs 38-47 ); aedeagus shaped as in Figs 42-47 View Figs 38-47 , internal sac with series of six stout, long, and distinctly sclerotised spines ( Fig. 47 View Figs 38-47 ).

Etymology: The name (Lat., adj.) refers to the presence of six stout spines in the internal sac of the aedeagus.

Comparative notes:

Based on the male sexual characters, especially the morphology of the aedeagus (shape of apex of ventral process, shape of spines in internal sac), S. sexspinosus   is the adelphotaxon of S. fortespinosus   . Both species are reliably distinguished only by the male primary sexual characters, particularly the shape of the apex of the ventral process (see Figs 30- 34 View Figs 25-36 , 42-45 View Figs 38-47 ), as well as the number and colour of the spines in the internal sac (darker in S. fortespinosus   than in S. sexspinosus   ).

Distribution and bionomics:

The type locality is situated some 15 km to the northeast of Muğla ( Map 1 View Map 1 ). The type specimens were found under stones and sifted from grass roots between limestone gravel on a pasture with shrubs, very close to a field, at an altitude of about 1200 m ( Fig. 48 View Fig )   .
