Visual representation of Tatuidris pilosity patterns Four pilosity patterns (patterns of hair-like setae) are known to occur within Tatuidris collections. Pilosity pattern A consists of a mix of both long flexuous and short appressed setae. This is the most common pilosity pattern and the one that most resembles the type specimens from El Salvador and the gyne from Otongachi, Ecuador. Pilosity pattern B is characterized by very short, fully appressed, and regular spaced setae arrayed homogeneously and equidistantly on the head, mesosoma, petiole, postpetiole and gaster.
|
|
Pilosity pattern C is characterized by dense lanose- looking setae. Pilosity pattern D consists of short and uniform decumbent (strongly inclined but not fully appressed) setae scattered throughout the body.

The workers of P. fervens can be easily confused with those of P. teneriffana. Morphologically the minor workers are best separated by coarse, mostly suberect scape pilosity, impressed metanotal groove, relatively smaller eyes and shorter spines in P. fervens versus decumbent to subdecumbent scape pilosity with longer suberect hairs along outer edge, inconspicuous metanotal groove in profile, and larger eyes and longer spines in P. teneriffana. The major workers of P. fervens are recognizable by having longer scapes and a narrower postpetiole in dorsal view than P. teneriffana. In P. fervens, the pilosity in the face and on the metatibia is coarser and at least partly suberect, and the punctures on the sides of the face are stronger than the thinner and more decumbent to subdecumbent pilosity and superficial punctures on the sides of the face in P. teneriffana.

Ekrixanthera ehecatli is a species of extinct plant first described from fossilised flowers from Mexican amber. Its flowers lack pedicels and are pentamerous and staminate; they have a pistillode with reduced pilosity; glabrous heteromorphic tepals with truncate tips. Differentiating it from Ekrixanthera hispaniolae are the presence or absence of a pedicel, the heterotrophic tepals, and the presence or absence of pilosity of its pistillode and tepals. Additionally, the latter characters added to the pentamerous flowers separate the two fossil species from extant genera.

With all these easily visible differences between the minor workers of the two species, especially their very distinct pilosity patterns, the chance that P. loki is a morphologically aberrant conspecific of P. jonas is probably small.

The queen is highly polymorphic, differing in size, pilosity, sculpture (shininess) and colouration. The genus Doronomyrmex was synonymized with Leptothorax as a junior synonym by Heinze (1998),Heinze, J. 1998 ("1995"). The origin of workerless parasites in Leptothorax (s. str.)

T. legatus is most easily distinguished from T. rex and T. dux by differences in pilosity, sculpture and the shape of the petiole and postpetiole. T. rex is almost lacking pilosity on the mesosomal dorsum, while the whole dorsal surface is covered with long erect hairs in T. legatus and T. dux. The foveolation is weaker in T. rex, especially on the mesosoma where the foveae on the mesosoma are small with most interspaces equal or wider than their diameter. T. legatus can be most easily separated from T. dux by the shape of the petiole, which is much more robust in the former.

Lenhart, Dash & MacKay (2013) recognized Dinoponera lucida as a valid species based on the unique suite of characters including a tooth-like process on the pronotum, smooth and shiny integument, long and flagellate pilosity and petiole slanting forward on the dorsal edge. However, they note that a limited sample size restricted the certainty with which they could assert that Dinoponera lucida is a separate species because a broad spectrum of intraspecific variation may not be represented. There may be a possibility of character integration with Dinoponera australis in the area between the states of São Paulo and Rio de Janeiro. Dinoponera lucida is only slightly larger than Dinoponera australis but differs in its integument micro-sculpturing and pilosity type.

Closely resembling the worker in the structure of mandibles, clypeus, petiole, postpetiole and gaster in addition to sculpture, color and pilosity. Head with a single well-defined depression in place of the median ocellus. Mesosoma in dorsal view with a promesonotal suture but lacking sclerites associated with alate queen. Mesonotum is more convex.
|
|
The head is long and wide, with the eyes alone measuring . The vertex is covered in sparse pilosity with setae. Ocelli are present on top of the ants' head, precisely located just above the dorsal tangent. The base of the antennae emerges from the scrobes, which are equally as long as the scape.
|
|
They are dark grey to black in colour, with tellingly, copious stiff, almost snow-white hairs on the thorax and gaster. The antennae and tarsi are ferruginous, and the mandibles dark castaneous red. In addition to the thick and blunt white pilosity it is covered with a more yellowish, short and fine, decumbent pubescence.

Eumenes dubius can reach a length of about 13 millimetres. The first metasomal segment is narrow and elongated, creating a "bulbous" appearance to the abdomen. Body is black with yellow markings. These wasps lack of standing hairs on the first tergum and show a very short general pilosity, with a short pubescence on head's rear.
|

Female legs are almost completely black, with very small yellow spots. The anterior sides of the tarsal segments of each leg of female A. manicatum have fine, soft and small white-colored hairs. This pilosity occurs in most species of Anthidium in the Western Palearctic region. Male A. manicatum resemble A. maculosum in appearance.

This is a large shrew growing to a head-and-body length of about with a tail of . The pelage is long, both dorsal and ventral fur being greyish, while the legs are darker grey. The tail is thick and densely- haired, dark grey, with bristles long and a pilosity of 70 to 80%. The hind feet are both long and broad.
|
|
The punctures are from where pilosity arises, and these are often elongated on the dorsal and ventral portions of the head. On the thorax, striae are present, but they are less engraved with fewer punctures than in S. richteri. On the petiole, the punctates are located on the sides. The postpetiole, when viewed above, has a strong shagreen with distinct transverse punctostriae.

Species of this genus are predominantly ground-nesting and, when disturbed, will display thanatosis enhanced by crypsis, i.e., individuals will accumulate dirt in their pilosity and play dead. With respect to diet, most species are omnivores and facultative granivores, while others, including the whole M. diversus species group, are specialist granivores. At least one species, the Malaysian rainforest-dwelling M. mucronatus is known to have a trophobiotic relationship with hemipterans.

The plants and animals of tropical montane páramos display striking adaptations to cool, wet conditions and intense sunlight. Around the world, characteristic plants of these habitats display features such as rosette structures, waxy surfaces, and abundant pilosity. The páramos of the northern Andes are the most extensive examples of this habitat type. Although ecoregion biotas are most diverse in the Andes, these ecosystems are distinctive wherever they occur in the tropics.

Workers of this species can be recognized by the following combination of character states: anterior inferior pronotal corner with tooth-like process, pilosity long and flagellate with white luster, integument smooth and shiny with bluish luster, scape length longer than head width, petiole slanting obliquely on dorsal edge. Total body length ranges from 27–30 mm which is between the lengths of Dinoponera australis and the other larger species. Males are unknown.
|
|
The pilosity appears similar to that of S. richteri. These hairs are erect and vary in length, appearing long on each side of the pronotum and mesonotum; on the head, the long hairs are seen in longitudinal rows. Numerous appressed pubescent hairs are on the petiolar scale; this is the opposite in S. richteri, as these hairs are sparse. Workers appear red and somewhat yellowish with a brown or completely black gaster.

Ekrixanthera hispaniolae is a species of extinct plant first described from fossilised flowers from Dominican amber. It has staminate flowers on short pedicels that are pentamerous, with a pilose pistillode, plus heteromorphic pilose tepals. Differentiating it from Ekrixanthera ehecatli are the presence or absence of a pedicel, the heterotrophic tepals, and the presence or absence of pilosity of its pistillode and tepals. Additionally, the latter characters added to the pentamerous flowers separate the two fossil species from extant genera.

The tarsus is fuscous, and the mandibles are rugose. In contrast to the workers and queens, the funicular joints are shorter, the sculpture is denser on the head and thorax, the number of punctures is less than that of the other castes and the postpetiole is coarser. The first segment of the gaster is transversely roughened, and the pilosity (hair) on the legs is less dense. The genitalia of the male is consistent with other formicids, composed of an outer, middle, and inner pair of valves.

The undersides of the femora, petiole and scapes bear longitudinal concavities, presumably for reception of retracted limbs. Pilosity on head and body is pale and erect to suberect. Of all described congeners L. reticulata most closely resembles the Japanese L. azumai, which is also heavily sculptured in a regularly intersecting rugoreticulate pattern on head, alitrunk and gaster. Lordomyrma reticulata is distinguished by the shape of the petiole, as the peduncle is clearly shorter than the length of the node whereas L. azumai presents a distinctly elongate peduncle.

The minors are most similar to those of P. braueri, differing from the latter by slightly smaller eyes and decumbent to subdecumbent versus mostly suberect scape pilosity in P. braueri. The majors look like an odd hybrid of those of P. braueri, P. jonas, and P. decepticon, with the head in full-face view somewhat resembling that of P. decepticon, the mesosoma in profile similar to P. jonas and the postpetiole shape closest to P. braueri. This combination, however, makes this species unique and easily identifiable on the islands of the Malagasy region.

Workers of this species is recognized by its finely micro- sculptured integument which is not shiny, rounded anterior inferior pronotal corner lacking a tooth-like process, ventral side of the head lacking any gular striations and long/flagellate pilosity. Males are distinguished by the long fine setae of the second funicular segment, light brown coloration, long narrow parameres, volsella with two small basal teeth and lacking a lobe on the distal edge of digitus volsellaris. Dinoponera quadriceps may be confused with Dinoponera mutica, but has a finely micro-sculptured integument which is not shiny, lacks gular striations and has a petiole which bulges on the dorso- anterior edge in contrast to Dinoponera muticas roughly microsculptured integument, striated gula and petiole with even, non-bulging corners. Dinoponera quadriceps and Dinoponera mutica differ in micro-sculpturing, gular striations and petiole shape.
