Identification

Prebus (2021) – A member of the pulchellus group of the Temnothorax salvini clade. Temnothorax ciferrii can be separated from all other species in the salvini clade by the following character combination: head in full face view with posterior margin flat to slightly convex; antennal scapes very long, surpassing the posterior margin of the head by about two times the maximum width of the antennal scape; compound eyes relatively small, with nine to eleven ommatidia in the longest row; in profile view, dorsum of mesosoma evenly, strongly convex; pronotal declivity indistinct; metanotal groove not impressed; propodeum not depressed below the level of the promesonotum; propodeum bearing standing setae dorsally; propodeal spines longer than the propodeal declivity, directed posteriorly, and weakly downcurved; hind femora weakly to moderately incrassate; petiolar node flat and elongate dorsally; transition of dorsal to posterior face of petiolar node marked by an angle; in dorsal view, apex of petiolar node narrower or slightly wider than the caudal cylinder of the petiole; postpetiole very broad: greater than or equal to 2.3 times the width of the petiole; dorsum of head smooth and shining; petiolar node with four erect setae dorsally; setae on head, mesosoma, waist segments and gaster erect, moderately long, sparse and blunt (never long and tapering); integument variously colored: either predominantly dark brown, with the antennae, pronotal neck, propodeal spines, and tarsi testaceous, mandibles and tibiae nearly white, or: femora, meso- and metacoxae light yellow in addition to the previous color scheme, or: pronotum, procoxa, petiolar node, and base of gaster in yellow in addition to the previous color scheme.

Similar species: Temnothorax flavidulus, Temnothorax harlequina, Temnothorax hippolyta, Temnothorax magnabulla, Temnothorax pulchellus, and Temnothorax terricola. The erect setae count of four on the dorsum of the petiolar node differentiates T. ciferrii from T. terricola and T. hippolyta, which have only two along the posterior margin. The flat relatively small compound eyes, with nine to eleven ommatidia in the longest row, and dark integument separate T. ciferrii from T. flavidulus, which has 12 ommatidia in the longest row of the compound eye and is uniformly light yellow. The presence of erect setae on the propodeum distinguishes T. ciferrii from T. pulchellus. The strongly convex dorsal margin of the mesosoma and angulate transition between the dorsal and posterior faces of the petiolar node distinguishes T. ciferrii from T. magnabulla, in which the mesosoma is flatter and the petiolar node transition is evenly rounded. Temnothorax ciferrii and T. harlequina can be separated most easily by the color of the integument: T. harlequina has a light yellow gaster, whereas the gaster of T. ciferrii is always dark brown, or brown with the anterior quarter of the first gastral tergite yellowish. The structure of the clypeus may also be used to separate the two species: T. harlequina has an evenly convex anterior margin of the clypeus, whereas T. ciferrii has a medially flattened anterior clypeal margin. The medial two pairs of setae on the anterior clypeus margin may also be used to separate T. harlequina and T. ciferrii: in T. ciferrii, the setae flanking the central pair are thickened to nearly twice the width of the central pair, whereas in T. harlequina they are nearly the same width.

Baroni Urbani (1978) - T. ciferrii is similar to Temnothorax albispinus but differs with its smooth and shiny mesosoma and distinctive whitish spine. Also similar to Temnothorax terricola from Cuba but ciferrii is larger, > 2 mm, and has a black body; terricola is smaller > 2 mm and is brown. Also see the remarks in the nomenclature section below.

Biology

Temnothorax ciferrii is known from a few geographically distinct collections. The type series was collected from the Los Siete Hermanos islands, a group of small, uninhabited islands off the northern coast of Hispaniola near Monte Cristi, which are dominated by mangroves and xerophytic vegetation. Two additional series of workers and a dealate gyne were collected from Jaragua National Park in southern Hispaniola. The details of the type collection are not known, but the latter two were made from soil in low lying dry forest and leaf litter in mid-elevation transitional forest, respectively. The biology of this species remains unknown but is likely to be similar to other members of the ground or litter nesting, pan-Caribbean pulchellus group.

Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.

Prebus (2021) - Temnothorax ciferrii is part of a large complex of species endemic to the island of Hispaniola and its smaller outlying islands, including T. flavidulus, T. wilsoni, T. balaclava, and T. bahoruco, none of which have been collected in sympatry. While it is possible to distinguish T. ciferrii from each of these taxa based on morphology, it remains to be seen whether this putative species is simply a variant of a widespread, morphologically diverse species. I have observed a couple of color variants of T. ciferrii, which were also noted by Baroni Urbani (1978): both have dark mesosomata, but the degree of infuscation on the legs varies (see worker images, figures 139 g-l, above in the caste section). In the first formal morphology-based phylogenetic work including this species, Fontenla Rizo (2000), while not including all of the taxa in Baroni Urbani's pulchellus group, corroborated these relationships to some degree, with the caveat that T. terricola and T. torrei fell outside of this group. Combined molecular and morphological analyses (Prebus, in prep.) mostly agree with Fontenla's analysis. The type specimens of T. ciferrii were not examined in this revision, so while the original description of T. ciferrii closely matches the characteristics of the more southern collections, these may be yet another, distinct member of the flavidulus complex.

As noted by Baroni Urbani (1978), this species closely resembles T. flavidulus, which is known only from the type specimens collected from Manneville, Haiti. Baroni Urbani (1978) uses the conformation of the postpetiole as a character that distinguishes T. flavidulus from T. ciferrii, with T. flavidulus having more angulate anterior corners of the postpetiole. My observations of the types of T. flavidulus offer several more distinguishing characteristics, for example the eye of T. flavidulus is distinctly larger than that of T. ciferrii.

Baroni Urbani (1978) - Temnothorax ciferrii e specie prossima a Temnothorax albispinus ed alla sua forma pallipes dell'isola Mona, per taglia, colorazione e morfologia generale e soprattutto per la morfologia delle spine propodeali e per il singolare sviluppo del postpeziolo. Le due specie sono peraltro facilmente distinguibili per alcuni dettagli morfologici minori che appaiono dalle rispettive figure e soprattutto per il peziolo (piu brevemente peduncolato in albispinus) e per il tegumento pressoche interamente liscio e lucidissimo in ciferrii in luogo di minutamente zigrinato ed opaco come in albispinus. Quest'ultimo carattere avvicina notevolmente ciferrii a Temnothorax terricola (Mann) di Cuba, tanto che per qualche tempo avevo considerato la possibilita di sinonimizzare le due specie. In base all'unico esemplare da me esaminato ciferrii differisce da terricola soprattutto per la taglia leggermente maggiore (cfr. tutte le misure qui citate) e per il colorito piceo. Lo stesso Menozzi, pero, nella descrizione originale, menziona la presenza di esemplari brunicci. I femori pero, sembrano costantemente colorati in modo diverso e lo scapo di ciferrii e anche proporzionalmente piu lungo (ISC 104,35, mentre, in terricola ISC > 113). Data anche l’allopatricita delle due popolazioni, la loro separazione specifica mi sembra pertanto la soluzione piu ragionevole

In full-face view, head subquadrate, longer than broad (CI 82–87). Mandibles weakly striate, shining, and armed with five teeth: the apical-most well developed, followed by a less developed preapical tooth and three equally developed smaller teeth. Anterior clypeal margin entire and evenly rounded. Antennal scapes very long: when fully retracted, extending past the posterior margin of the head capsule by about two times the maximum width of the scape (SI 91–104). Antennae 12-segmented; antennal club of three segments, with the apical-most segment about as long as the preceding two in combination. Frontal carinae short, extending past the antennal toruli by about one and a half times the maximum width of the antennal scape. Compound eyes moderately protruding past the lateral margins of the head capsule. Lateral margin of head evenly convex, forming a continuous arc from the posterior of the head to the mandibular insertions. Posterior head margin weakly convex, rounding evenly into the lateral margins.

In profile view, compound eyes ovular and moderately large (OI 24–25), with 9 ommatidia in longest row. Pronotal declivity indistinct, neck and anterior face of pronotum forming a ~120° angle.

Promesonotal suture extending from the posterior margin of the procoxal insertion only to the mesothoracic spiracle, which is well developed. Metanotal groove visible as a disruption of the sculpture laterally from where it arises between the mid- and hind coxae to where it ends in the poorly developed metathoracic spiracle. Propodeal spiracle poorly developed, directed posterolaterally, and separated from the propodeal declivity by about three spiracle diameters. Propodeal spines well developed and long (PSI 39-45), about one and a quarter times the length of the propodeal declivity, tapering evenly from the base, weakly downcurved, and acute. Propodeal declivity straight and flat, angled anteriorly so that it continues the even curve of dorsal surface of the mesosoma, forming a ~100° angle with the base of the propodeal spines. Propodeal lobes rounded and weakly developed. Metapleural gland bulla small, extending from the metacoxal insertion one quarter of the way to the propodeal spiracle. Petiole moderately long (PLI 146-187), without tubercles anterodorsally. Subpetiolar process in the form of a small, very acute tooth; ventral margin of petiole weakly concave posterior to it. Petiolar peduncle short: comprising roughly a third of the length of the petiole. Petiolar node robust: transition between peduncle and node marked by a rounded angle of ~150°, resulting in a weakly concave anterior node face; anterior face forming a ~120° angle with the dorsal face, which is long and weakly convex, nearly flat; dorsal face rounding evenly into the short posterior face, which forms a ~110° angle with the caudal cylinder.

Petiolar peduncle with spiracles slightly protruding past the lateral margins, peduncle not noticeably constricted anterior to them. Petiolar node evenly ovate and narrowest anteriorly, slightly wider than the peduncle, and evenly grading into the caudal cylinder, which is slightly wider than the node. Postpetiole very broad (PWI 229-270) and campaniform, articulating with nearly the entire anterior margin of the gaster. Anterior margin of the postpetiole broadly convex, with the corners evenly rounding into the lateral margins, which diverge to the angulate posterior corners; posterior margin broadly concave. Metafemur weakly to strongly incrassate (FI 227-321).
