Diversitermes diversimiles: Mathews 1977: 180 [imago, soldier, figs. 124–127]; Krishna et al. 2013: 1569 –1570 [catalog] Imago ( Figs. 1 E–1H, 2B, 2E, 3B, 3E). Head capsule brown, paler near postclypeus, eyes and antennal sockets. Postclypeus yellow brown; midline darker. Labrum yellowish, hyaline. Frontal marks inconspicuous. Ecdysial line inconspicuous. Antenna yellow brown. Pronotum yellow brown. Mesonotum yellow brown. Metanotum yellow brown. Legs yellow. Tergites and sternites yellow brown. Wings brownish, hyaline; anterior veins darker. Head capsule densely covered with short inclined hairs and 6–10 short bristles. Postclypeus with numerous hairs, less dense than on head capsule. Labrum with about 10 bristles and many short hairs. Pronotum densely covered with hairs, more numerous near margins. Tergites and sternites densely covered with decumbent hairs, with a row of bristles on posterior margin and another irregular and shorter line of bristles near middle. Wings with short hairs on surface; anterior margin with longer hairs. Head capsule oval, with slightly angular posterior corners. Fontanelle conspicuous, Y-shaped. Eye nearly circular, medium-sized, distance to lower margin of head about 1/6 its diameter. Ocelli oval, large and prominent, separated from eye by about half their width. Postclypeus inflated; anterior margin nearly straight; posterior margin convex. Pronotum with anterior margin nearly straight, slightly emarginate; sides convex converging posteriorly. Posterior margin of meso- and metanotum broadly V-shaped; posterior points roughly rounded, irregular. Wing microsculpturing: margins and veins with pointed papillae; membrane covered with dense asteroid micrasters (6–8 points). Antenna with 15 articles: 3>6>5=4=2. Measurements in Table 1 .

Major soldier ( Figs. 4 D–I; 7C–D). Head brown; basal ¾ of nasus very dark brown, apex light brown. Articles 1–2 of antenna yellow brown; other articles light brown, with a marked contrast between articles 2 and 3. Thoracic nota and legs yellow brown. Tergites yellowish, paler than thoracic nota. Sternites paler than tergites. Head capsule with 2 bristles on vertex and 4 at base of nasus, and numerous microscopic hairs. Nasus densely covered with short inclined hairs, and 4 longer ones at tip. Pronotum with 0–2 bristles on anterior margin and with sparse microscopic hairs on surface. Meso- and metanotum without bristles. Tergites with 4–6 bristles on posterior margin and many microscopic hairs on surface. Sternites densely covered with inclined hairs and with a row of 6–10 bristles on posterior margin. Head capsule pear-shaped, with strongly convex sides. Nasus usually short, narrow and subcylindrical. Line of top of head with nasus concave in profile. Antenna with 13 articles: 3>2>6>5>4; 3rd article about as long as 1st and about twice as long as second. Measurements in Table 2 .

Intermediate soldier ( Fig. 5 D–F). Coloration, chaetotaxy and antennae similar to those of major soldier; head capsule lighter colored. Smaller and with a distinct constriction behind antennae. Nasus shorter, slightly upturned and dilated near apex. Measurements in Table 3 .

Minor soldier ( Fig. 6 D–I). Coloration lighter than in intermediate and major soldiers. Head capsule wider posteriorly; with distinct constriction behind antennae. Top of head in profile with convex elevation between constriction and nasus. Nasus upturned, dilated near apex and with fewer hairs than in intermediate and major soldiers. Antennal articles: 6>5=3>2>4. Measurements in Table 4 .

Worker ( Figs. 8 C–D; 9D–F; 10H–O; 11D). Head capsule yellow to brownish yellow. Epicranial suture and fontanelle spot conspicuous. Antennae, thorax, legs, tergites and sternites yellowish, unpigmented. Head capsule with scattered bristles and hairs. Pronotum with 2–6 bristles on anterior lobe and sparse short hairs. Meso- and metanota with a few short hairs, without bristles. Tergites with a row of bristles on posterior margin and sparse short hairs on surface. Antenna with 14 articles. Measurement in Tables 5 and 6 .

Distribution. Diversitermes diversimiles occurs in a large region, including parts of Brazil, Bolivia, Paraguay and Argentina, mainly in forest habitats ( Fig. 13 ). It is apparently rare in the Amazon region.

Remarks. According to Krishna et al. (2013: 1569), the type series of Eutermes strelnicovi includes imagoes of Subulitermes microsoma ( Silvestri 1903) and minor soldiers of Diversitermes castaniceps . John (1920) did not designate a holotype and the location of the syntypes is unknown. However, the soldier shown in John's illustration (his Fig. 3 ) matches the minor soldier of D. diversimiles , not D. castaniceps . Also, the type locality of E. strelnicovi ( Brazil: Mato Grosso: São Domingos) is out of the geographic range of both D. castaniceps and D. tiapuan , sp. n.

Etymology. The name “ diversimiles ” is derived from the Latin words “diversus” (diverse) and “miles” (soldier), and refers to the polymorphic soldiers. The spelling “ diversimilis ” used by several authors (e.g. Snyder 1949) is incorrect.

Type material examined. Lectotype, here designated: major soldier ( AMNH), collected by F. Silvestri, x.1900. Type-locality: PARAGUAY: Paraguarí (lat 25.633°S, long 57.15°W) . Paralectotypes: soldiers, workers, imagoes, same data as lectotype ( AMNH, and in Silvestri's collection at the Instituto di Entomologia Agraria, Portici, Italy). Specimens from other localities mentioned by Silvestri (1903: 91) are not paralectotypes because Silvestri (1901: 7) mentions only the specimens from Paraguari. Raineri et al. (1992) list specimens from Villarica , Paraguay as “Typi” (types) of D. diversimiles . However, these specimens were not mentioned in the original description and were not syntypes .
