Anchophthalmus modestus Fairmaire, 1887; by original designation.

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.

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).

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

The types of Selinus calcaripes seems to be lost. According to the information provided by Iwan (2002b) they should be deposited in Naturhistorisches Museum collection (Basel, Switzerland). Unfortunately, the curators do not confirm this statement. Additionally, during the preparation of my recent scientific project – Phylogeny, biogeography and generic classification of the Ectateus generic group (Coleoptera: Tenebrionidae: Platynotina) – I have studied diverse entomological material concerning the subtribe Platynotina from several collections across the World and I did not menaged to locate these specimens.

Based only on the original species descriptions Koch (1956) proposed to consider Selinus calcaripes as a synonym of Ectateus curtulus (Fairmaire, 1893). Unfortunately, the morphology of the holotype of Ectateus curtulus (damaged female – Fig. 47) do not correspond to Gebien’s (1904) description of Selinus calcaripes and Koch’s (1956) interpretation of Ectateus curtulus. Both publications refer rather to a morphological form that is very closely to Ectateus modestus and differers from it mainly by the structure of male protibiae (Figs 31–32). A consistent to the above mentioned descriptions morph was found in the studied material. It was included in the cladistic analysis as Selinus calcaripes.

The results of a cladistic analysis confirmed the aforementioned assumption that Ectateus curtulus and Selinus calcaripes represent two distinct morphological forms (Fig. 25). They can be easily distinguished by the structure of head (char. 3, 5), pronotum (char. 9) and elytra (elytral intervals with conspicuous punctures in Ectateus curtulus). Additionally, the results shows that Selinus calcaripes is very closely related to Ectateus modestus – which is consistent with Gebien’s (1904) description and Koch’s (1956) interpretation.

Taking into consideration the difficulties associated with Selinus calcaripes I propose to designate a neotype to clarify the taxonomic status of this species. Additionally, on the basis of the results of a cladistic analysis I propose to treat this taxon as a independent species – not as a synonym of Ectateus curtulus.

While describing Ectateus latipennis, Koch has noted that types of Ectateus crenatus were unknown to him. The characters used by Koch to separate those two species (body size, pronotum structure) were based only on the Fairmaire (1897) description. During the examination of available material I have not found any consistent morphological characters to separate those two species. Therefore, I propose to consider Ectateus latipennis as a synonim of Ectateus crenatus.

The examination of the type material representing Selinus monardi resulted in similar conclusions – there are no consistent morphological characters to separate it from Ectateus crenatus.

Ectateus villiersi Ardoin, 1965; here designated.

The presence of the basal depressions on the pronotal disc place Eleoselinus near to (Kamiński 2013c): Anchophthalmops Koch, 1956, Anchophthalmus Gerstaecker, 1854, Kochogaster Kamiński & Raś, 2011, Ectateus, Glyptopteryx Gebien, 1910, Microselinus Koch, 1956, Monodius, Nesopatrum Gebien, 1920, Phallocentrion Koch, 1956, Phymatoplata Koch, 1956, Platykochius Iwan, 2002, Platymedvedevia Iwan & Banaszkiewicz, 2007, Quadrideres Koch and Selinus.

Non-dimorphic legs distinguish Eleoselinus from: Anchophthalmops, Anchophthalmus, Ectateus, Microselinus, Monodius, Phymatoplata, Platykochius, Platymedvedevia and Selinus. From Kochogaster it can be easily distinguished by a triangular submentum and lack of sclerites in bursa copulatrix (Kamiński and Iwan 2013). Not parallel body sides separates Eleoselinus form Quadrideres and Glyptopteryx. Additionally, from the latter it can be distinguished by flat elytral intervals and slightly sinusoidal base of pronotum (Iwan 2002). Fine hairs covering the body surface, narrow apical segments of maxillary palps and long basal apophyses of aedeagal tegmen separates Eleoselinus from Phallocentrion (Iwan 2001a).

The following character combination is unique for Eleoselinus within the whole subtribe Platynotina: (1) anntenna robust, shorter than pronotum, (2) shallow anterior tentorial pits, (3) presence of apophyseal and basal depressions on pronotal disc, (4) intercoxal process of prosternum bellied, (5) metaventrite with coarse longitudinal depression, (6) 5^th abdominal ventrite unbordered, (7) non dimorphic legs and maillary palps, (8) elytral intervals with fine punctures, (9) curved, hook-shaped clavae and (10) longitudinal coxites of ovipositor.

Body length = 10.5–13.0 mm. Elytra wider and longer than pronotum (width ratio elytra / pronotum = 1.1–1.2; length ratio elytra / the middle of pronotum = 2.4–2.9).

Dorsal side of head dull, with fine punctures (the intervals between the punctures are greater than the 2 diameters of the puncture). Frontoclypeal suture fine. Clypeal emargination relatively deep (clypeal emargination width / depth ratio = 5.5–5.7). Mentum with median part wide. Submentum with short base. Maxillary palp not widened (width of maxillary palp / length of 3^rd antennomere = 1.0–1.2). Length of antennae slightly greater than pronotal length (ratio antenna / pronotum from tip of anterior pronotal angle to tip of posterior pronotal angle ca. 0.9). 3^rd antennomere relatively long (length ratio of antennomere 3^rd / 2^nd = 3.2–3.5).

Pronotal disc transverse (middle of pronotum length / width ratio = 0.5–0.6); dull, with fine punctures (the intervals between the punctures are greater than the 3 diameters of the puncture). Lateral margins of pronotum narrowing towards apex. Apophyseal and basal depressions on pronotal disc present. Pronotal hypomera dull, without punctures.

Elytra oblong (elytra length / width ratio = 1.1–1.3). Elytral striae with fine punctures (the intervals between the punctures are greater than the 2 diameters of the puncture).
