Pheidole inversaHNS Forel, new status

Pheidole radoszkowskii var. inversaHNS Forel 1901 j: 363.

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

etymology L inversaHNS, turned upside down, allusion unknown.

diagnosis A small reddish brown, nearly hairless member of the diligensHNS group, close to bruesiHNS of Grenada, diligensHNS and laidlowi of Brazil, and the widespread and very abundant Neotropical radoszkowskiiHNS and triconstrictaHNS. P. inversaHNS 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 bruesiHNS, as well as diligensHNS, may prove to fall within the substantial variation of radoszkowskiiHNS 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.
