Pheidole inversa Forel  HNS  , new status

Pheidole radoszkowskii var. inversa  HNS  Forel 1901 j: 363.

Types Lectotype and paralectotype: Nat. Mus. Nat. Hist. U.S. Paralectotypes: Mus. Hist. Nat. Geneve.

etymology L inversa  HNS  , turned upside down, allusion unknown.

diagnosis A small reddish brown, nearly hairless member of the diligens  HNS  group, close to bruesi  HNS  of Grenada, diligens  HNS  and laidlowi  of Brazil, and the widespread and very abundant Neotropical radoszkowskii  HNS  and triconstricta  HNS  . P. inversa  HNS  is distinguished from all these species by the following combination of traits.

Major: anterior two-thirds of head longitudinally carinulate, posterior one-third smooth and shiny; cephalic rugoreticulum absent; petiolar node relatively thick in side view; anterior three-fourths of median strip of first gastral tergite shagreened and opaque. Minor: posterior two-thirds of median strip of first gastral tergite shagreened and opaque.

This form and bruesi  HNS  , as well as diligens  HNS  , may prove to fall within the substantial variation of radoszkowskii  HNS  and thus become synonymous.

Measurements (mm) Lectotype major: HW 1.02, HL 1.08, SL 0.80, EL 0.20, PW 0.50.

Paralectotype minor: HW 0.56, HL 0.64, SL 0.76, EL 0.16, PW 0.38.

Color Major: body light reddish brown; appendages brownish yellow.

Minor: concolorous light reddish brown.

Range Northern lowland Colombia and Curacao.

Biology Unknown.

Figure Upper: lectotype, major (upper mesosomal profile, lectotype; lower mesosomal profile, major from Curacao). Lower: paralectotype, minor. COLOMBIA: Barranquilla. Scale bars = 1 mm.
