Cephalotes coffeae

Nothing is known about the biology of .

Identification
A member of the coffeae clade differing from its sister species, Cephalotes trichophorus, by the larger propodeal teeth with a short space between the second and third pair, and by the CI ≥ 112. The soldiers of coffeae have the head partially covered by a thin layer of camouflage material. (de Andrade and Baroni Urbani 1999)

 *  coffeae. Paracryptocerus (Harnedia) coffeae Kempf, 1953: 81, figs. 1-13 (s.w.q.m.) COLOMBIA. Combination in Zacryptocerus: Brandão, 1991: 385. See also: Kempf, 1958a: 104; in Cephalotes: De Andrade & Baroni Urbani, 1999: 560.

Worker
Kempf (1958) - Total length 3.9-4.7 mm; maximum length of head 1.09-1.24 mm; interocular width 1.09-1.24 mm, maximum length of thorax 1.12-1.28 mm. Black; the following ferruginous: tip of mandibles, scapes, thoracic and peduncular teeth, the tibiae and tarsites; frontal carinae testaceous with their edge light ferruginous; funicular segments fuscous-brown, becoming darker toward apex of funiculus; anterolateral gastral lobes with a light spot, light brown or ferruginous.

Head subopaque; quadrate, the interocular width always equal to the maximum length of head. Clypeal sutures vestigial. Lateral borders of head diverging very little caudad, straight, not emarginate in front of, nor noticeably upturned above, eyes. Occipital corners obliquely truncate with slightly crenulate border. Occipital border gently emarginate between the lobes. Upper face of head scarcely, but evenly convex, finely reticulate punctate, more coarsely reticulate-rugose and foveolate. Lower face of head identically, but much more superficially sculptured, rather shiny.

Thorax subopaque. Anterior border gently arcuate. Shoulders rectangular. Lateral borders of pronotum with two triangular teeth in front, followed by a more or less crenate border, the posterior corner rectangular. Promesonotal suture obsolete. Mesonotum, on each side, with a pointed, projecting tooth. Mesoepinotal suture mostly vestigial, usually fading out in the middle. Lateral border of basal face of epinotum with a subrectangular tooth on the anterior corner, followed behind by a large, triangular and somewhat foliaceous tooth, which again is followed by another similar, yet smaller tooth. Declivous face somewhat differentiated from basal face, its borders marginate but unarmed. Sculpture of dorsum of thorax as on head, the declivous face finely reticulate-punctate and opaque. Sides of thorax horizontally striatorugose. Fore coxae with rugosities on the outer face. Hind femora, as seen in profile, not fusiform, but the extensor face forms a distinct angle, the vertex of which is bluntly rounded.

Peduncular segments subopaque, their dorsal face sculptured as dorsum of head and thorax. Petiole not quite as broad as postpetiole, its anterior face truncate, forming dorsolaterally on each side a small tubercle at its junction with the dorsal face. Lateral processes spinelike, gently curved and pointed at apex. Dorsum of postpetiole flat, its lateral processes long with strongly recurved tip.

Gaster subopaque, oval, rather strongly emarginate anteromesially, its anterolateral lobes rather broad, bearing anteriorly a vestigial, very narrow, foliaceous crest, which does not reach caudad to the level of the stigma of the first tergite. The latter finely reticulate-punctate, reticulate-rugose, forming elongated meshes. First sternite with fine longitudinal rugosities on the sides.

Standing hair on mandibles, funicular segments and apex of gaster. A row of short, thick setae projects from the lateral edge of the frontal carinae, which reaches back to the occipital corner. Scalelike hair very distinctive, long, canaliculate, golden, appressed, on dorsum of head, thorax, peduncle, gaster and extensor face of femora and tibiae. Finer, simple or canaliculate on lower face of head, gastral sternites and sides of the leg segments.

Soldier
Kempf (1958) - Total length 5.3-5.4 mm; maximum length of head 1.57-1.62 mm; maximum width of head disc 1.48-1.52 mm; maximum length of thorax 1.48-1.50 mm. Black; the following fuscous-ferruginous: Mandibles, anterolateral portion of head disc; ferruginous: legs, first gastral tergite with four yellowish-brown spots, the posterior pair very small.

Head rather shiny, surmounted by an oval, deeply excavate, completely marginate disc, with its somewhat crenulate borders strongly raised, concealing the floor of the disc, when head is seen in profile. Lateral borders of cephalic disc convex, converging caudad, forming with the straight to slightly concave occipital border an obtuse angle. Clypeal sutures vestigial. Anterolateral portions of disc, above the antennal scrobes, slightly transparent, having in the middle, just in front of the center, a gently bulging convexity. Occipital lobes obliquely truncate at apex, the truncated border sharply marginate, continuing cephalad as a vestigial carina, toward the superior border of the eye, but fading out halfway before reaching it. Inferior border of cheeks not distinctly marginate. Floor of cephalic disc finely yet superficially or even only vestigially reticulate-punctate, either only coarsely foveolate, or reticulate-rugose and foveolate. Sides of head, occiput and lower face reticulate-rugose and foveolate.

Thorax somewhat shining on mesonotum, subopaque on pronotum and epinotum, opaque on sides. Pronotum much broader than mesonotum, its anterior border arcuate and convex in the middle, very slightly concave at the sides, its anterolateral corner dentate, its sides subparallel or slightly converging caudad in front of the transverse carina, strongly converging and slightly sinuate behind the carina, the latter very prominent, sharply edged and strongly raised, shallowly excised in the middle, when seen from the front. Promesonotal suture obsolete except on the sides. In profile the pronotum and mesonotum are at right angle, the vertex of which is formed by the transverse carina. Mesonotum flat, with a blunt, or obliquely truncated, projecting lobe on each side. Mesoepinotal groove deeply impressed. Basal face of epinotum gently transversely convex, its anterior corner bluntly rounded, its sides with a strong triangular, pointed tooth, followed at the posterior corner by a similar, somewhat smaller tooth, which is slightly raised, pointing laterad. Declivous face shallowly excavated, its sides marginate. Pronotum, in front of the carina, finely reticulate-punctate, coarsely and rather densely foveolate. Remaining portion of dorsum of thorax coarsely reticulate-rugose and foveolate, the rugosities highly shining. Sides of thorax and declivous face finely but sharply reticulate-punctate, with a few rugosities on the former. Coxae and femora as in worker.

Peduncolar segments and gaster as in worker, except for the posterior p air of light spots on the first gastral tergite. Anterolateral lobes of gaster sharply marginate, not crested. Pilosity as in worker, except for the following: Scalelike hair arising from the pits on cephalic disc shorter, and around the rim of the disc a row of thick, short, projecting setae, extending backward to the level of the eyes, where they continue on the sides until the occipital corner.

The four spots on first gastral tergite are lighter and much more extensive. No light spot on shoulders. In general as in soldier, with the differences peculiar to the caste.

Cephalic disc slightly more elongate, less excavate, the lateral upturned borders not concealing in profile completely the anteromedian convexity of the floor of the disc. Posterior third of disc nearly flat, the borders scarcely raised, the posterior border not distinctly truncated but rather rounded. Ocelli very small, lying in pits which do not differ in size from the squamiferous foveolae. Posterior pair of ocelli very close to the occipital border. Transverse pronotal carina less prominent, interrupted mesially, fading out laterally before reaching the sides of the thorax. Scutum coarsely foveolate. Scutellum reticulate-rugose and foveolate. Basal face of epinotum extremely short, with an obtuse tooth on each side, and another smaller tooth on the posterior corner. Declivous face somewhat excavate, very finely reticulate-punctate, almost smooth. Laterotergites of pronotum and mesopleura foveolate. Hind femora fusiform, not angulate above. Petiole with a short tooth on each side, the postpetiole with lateral processes, which are obliquely truncate. First gastral tergite much longer than thorax, nearly twice as long as broad. Only the first fourth of the first tergite bears fine rugulosities. Scalelike hair as in worker but finer and smaller. Standing hair also occurs all over the first gastral tergite, and sparsely, not regularly distributed, on peduncular segments, legs, and thorax. Wings infumated, with dark-brown veins, the pterostigma black. Veins in the apical field almost well developed, not quite vestigial.
