Ennius Stål, 1861
(updated 23 April 2005)
Ennius Stål, 1861: 199.
Paramecocoris (Ennius): Stål, 1865: 112.
Type Species: Sciocoris ater Dallas, 1851, by original designation.
Tribal Placement: StDl (1876) included Ennius in his "Myrochea et genera quaedam affinia" group.
Included Species:
|
ater (Dallas) longulus (Germar) morio (Dallas) monteironis Distant |
Comments: Linnavuori (1982) provided a key to three of the species, and also discussed the fourth, E. longulus. Bergroth (1914) had considered E. monteironis to be a junior synonym of E. longulus, but Linnavuori (1982) indicated that he had examined a single female specimen of E. longulus from South Africa; he noted the following differences: "It [E. longulus] is larger than the monteironis specimens studied, the lateral margins of the pronotum are more curvate and narrowly lamellate (much more broadly lamellate in monteironis), and the sides of the venter are more coarsely punctate. Thus although a full comparison is precluded by lack of sufficient material, E. monteironis seems to be a valid species."
Key to Species of Ennius (modified from Linnavuori, 1982)
|
1 Totally blackish |
ater (Dallas) |
|
- At least lateral margins of pronotum narrowly and broad ring in middle and hind tibiae pale |
2 |
|
2(1) Lateral margins of pronotum nearly straight; lateral margins of head less strongly converging apicad; puncturing, on head especially, coarser; scutellum longer, about 1.42-1.53 times as long as broad; pygofer with median lobes on apical margin large, also clearly visible in lateral aspect |
morio (Dallas) |
|
- Lateral margins of pronotum curvate; lateral margins of head strongly converging apicad from very base; puncturing finer; scutellum shorter, 1.33 times as long as broad; pygofer with median lobes on apical margin smaller, only slightly visible in lateral aspect |
