Technomyrmex hypoclinoides Santschi  HNS  , 1919: 89 - 90; (w). DEMOCRATIC REPUBLIC OF CONGO (= Belgian Congo, Avakubi , 6 Jan. (J. Bequaert) ( NHMB)  .

Axinidris parvus Shattuck  HNS  , 1991: 118; fig. 35 (w). LIBERIA, Paiata (= Payeta) (J. Bequaert) (MCZC) examined. NEW SYNONYMY (B. Bolton, pers. comm.).

Worker diagnosis. Antennal scape shaft without erect hairs and pronotum (Fig. 19) with 1 pair of long erect hairs and each propodeal spine with 1 long erect hair; head (excluding clypeus) with 2 pairs of erect hairs; medial propodeal carina absent; first tergum with 2 long erect hairs; gena shiny and finely imbricate; head and body yellow.

Worker measurements (mm) (n = 10). HW 0.45 - 0.52; HL 0.53 - 0.62; SL 0.38 - 0.42; EL 0.13 - 0.17; OVD 0.21 - 0.27; PNW 0.31 - 0.35; PPW 0.21 - 0.26; WL 0.72 - 0.78. Indices. CI 81 - 88; CNI 67 - 75; OI 28 - 32; SI 79 - 83.

Worker description. The worker has been adequately described by Shattuck (1991).

Queen and male unknown.


I have examined the two type specimens of A. parvus  HNS  and others from the following localities. GABON, Ogooue Prov., Maritime Res. Mons Doudou ( CASC)  ; KENYA, Kakamega Forest, Isecheno and Isiukhu (AKRI, LACM)  .


The type of Technomyrmex hypoclinoides Santschi  HNS  was examined by B. Bolton who informed me that it is a senior synonym of A. parvus  HNS  . Both the new combination and new synonymy should be attributed to Mr. Bolton.

The few additional specimens available somewhat amplify the range of size variation, but otherwise are in good agreement with the type specimens and with Shattuck's original description. The presence of a single pair of relatively long erect hairs on the pronotal disc and a single such hair at the apex of each propodeal spine is an unusual feature shared only with A. bidens  HNS  , a larger and darker species. Both species are present in the Kakamega forest of Kenya, but A. bidens  HNS  is encountered much more frequently.

Photomontage images are available at www. antweb. org as Axinidris  HNS  sp. 1.
