Name

Ectateus Koch, 1956 – Wikispecies link – ZooBank link – Pensoft Profile

  • Ectateus Koch, 1956: 230. – Iwan 2001b[1]: 352, 2002a[2]: 66, 2002b[3]: 265, 2004a[4]: 541, 2004b[5]: 739; Iwan and Banaszkiewicz 2007[6]: 725; Kamiński and Raś 2011[7]: 647; Kamiński 2013a[8]: 85; Raś and Kamiński 2013[9]: 381.

Type species

Anchophthalmus modestus Fairmaire, 1887; by original designation.

Diagnosis

The following character combination is unique for Ectateus within the whole subtribe Platynotina: (1) fronto-clypeal suture coarse, clearly visible, (2) anterior pronotal angles curved outwards, (3) pronotal margins strongly erected upwards, (4) apophyseal depressions rounded, (5) pronotal base narrower than elytral base, (6) posterior pronotal angles strongly protruding towards elytra, (7) scutellum impressed, (8) elytral intervals with transverse sculpture (9) male protarsi relatively narrow, (10) male protibia slender (length/width = 4.0–5.6) and (11) clavae curved, hook-shaped.

Distribution

Ectateus specimens have been collected in the following ecoregions of Central Africa (Cameroon, Central African Republic, Democratic Republic of the Congo, Equatorial Guinea, Gabonese Republic, Republic of Rwanda, Republic of the Congo, South Sudan): Albertine Rift montane forests, Angolan Miombo woodlands, Atlantic Equatorial coastal forests, East Sudanian savanna, Mount Cameroon and Bioko montane forests, Northeastern Congolian lowland forests, Northwestern Congolian lowland forests, Northern Congolian forest-savanna mosaic, Southern Congolian forest-savanna mosaic, Western Congolian forest-savanna mosaic (Fig. 41).

Species included (5)

Ectateus calcaripes (Gebien, 1904), comb. n., Ectateus crenatus (Fairmaire, 1897), Ectateus curtulus (Fairmaire, 1893), Ectateus ghesquierei Koch, 1956 and Ectateus modestus (Fairmaire, 1887).
