Camponotus crispulus Santschi 1922  b. NEW STATUS.

Camponotus (Myrmaphaenus) blandus  var. crispula Santschi 1922 b: 110  . [w syntypes examined, NHMB; Cabana, Córdoba, Argentina  (Scott)].

Camponotus (Myrmaphaenus) blandus  st. crispulus Santschi 1929 b: 315  . Camponotus (Myrmaphaenus) blandus  var. crispulus Santschi. Kempf 1972: 44  .

Camponotus crispulus  is locally sympatric in Paraguay with at least two other species in the C. blandus  complex, most frequently the similarly-colored C. rosariensis  . Both species share a similarly dense pubsence over most of the body and a common bicoloration consisting of a red head and mesosoma and a dark gaster. However, C. crispulus  is structurally more compact, with shorter appendages and a relatively tall propodeum. In my experience, the easiest character to separate C. crispulus  from other bicolored blandus- complex species is the unique pattern of pubescense on the gaster. While all species in the complex show some degree of medial convergence in the appressed setae on the gastric terga, in C.

crispulus  this convergence is extreme, starting on the first gastric tergite (= abd. tergite 3) well ahead of the posterior margin and continuing to the apex of the gaster almost as a visible line. Because of the distinct morphological separation in sympatry between C. crispulus  and other closely-related forms, I find unambiguous the elevation of C. crispulus  to species.

Material from Paraguay is a close match to Santschi’s types from Córdoba, although Santschi’s material is somewhat more pubescent. F. Smith’s C. blandus  holotype worker ( BMNH, examined- see discussion under C. pellitus  ) from Pará is clearly a different species, as that ant is more gracile  than C. crispulus  and lacks the distinct pubescence.
