8. Melanotus miscellus Quate, new species 



Figures An, 9c 

 Melanosis communis var. B. — Dietrich, 1945, p. 57. — Severin, 1949, p. 16. 



Male. — Same as communis, except averages little smaller in size, 

 often darker reddish brown, and genitalia differ in being shorter, 

 aedeagus wider, paramere thicker, and with broader and shorter 

 apical blade, blade with dense cluster of hairs. Ratio of pronotal 

 width/length =1.2 (1.1-1.3). 



Elytron, holotype 8.9 mm; paratopes 8.5±0.4 mm (7.6-9.7). 

 40 spec. 



Female. — Similar to male except sexual differences. Genitaha as 

 figured; differs from communis in that spines of bursa nearer apex, 

 spermathecal duct, spermathecal duct diverticulum and accessory- 

 gland arise independently from bursa, accessory gland base far re- 

 moved from base of spermathecal duct. 



Elytron: Allotype 8.7 mm; paratypes, 8.5±0.4 mm (7.8-9.5).

This species appears intermediate between similis and communis. 

 External characters of color and pronotal punctures resemble com- 

 munis, but the male genitalia more closely resemble similis; the 

 position of spines of the female bursa is as in similis, but the shape of 

 the spines is like that of communis. The genitalia structures, however, 

 are distinct and although not easily recognized, seem constant. The 

 larvae, according to Lane (in litt.), are also distinctive.
