Akalyptoischion hormathos Andrews 1976 a: 9
Description. Length 1.10–1.25 mm. Width 0.35–0.37 mm. Body elongate, subparallel, uniformly orange/brown to reddish brown; glabrous; head narrower than pronotum by one eye width, sides slightly sinuate, anterior head not much narrower than posterior head; clypeus narrowing at 45u angle anterior to antennal insertions; head foveae shallow, indistinct, size of eyes; head punctation irregular, not very dense, surface rugose; eyes small, not prominent and appressed to head, with 4 or 5 small facets; eyes sometimes unpigmented and indistinct; tempora 1/2 to 3/4 eye width; hind angles rounded, greater than 90u; clypeal fovea length of antennomere V, 0.7 times width of labrum; labrum anterior margin deeply and evenly emarginate; mandible apex pointed with an apical tooth and 3–4 subapical serrations decreasing in size basally, prostheca short; antennae with a 3- segmented club; antennae reach hind angles of pronotum; antennomere I wider than long, a slightly irregular oval, II slightly longer than wide, oval, III small, slightly elongate, sides arcuate, IV–VIII small, submonilliform, IX–XI form club, IX large, globular, X larger than IX, sides parallel, XI larger than X, parallel sided, elongate trapezoid.
Pronotum widest anteriorly, anterior angles rounded, lateral margin straight sided and converging slightly posteriorly; lateral margin slightly explanate with,10 small tubercles spaced far apart, each bearing a microscopic seta; median 2/3 raised; pronotal foveae indistinct, each oval shaped and limited to base of raised area; pronotal punctation irregular and not dense, surface rugose.
Elytra subparallel, lateral flange present in anterior 1/3 only; 6 striae; strial punctures large and touching each other; humeral angle evenly rounded, not lobed; strial interspaces 3 and 5 gently raised, not carinate; interspaces glabrous; epipleuron complete, narrowing posteriorly.
Ventral surface glabrous; submental fovea length of antennomere IV with few large punctures and sparse micropunctures; ventral head punctation even, not dense and sparser at midline; gular punctation very sparse and irregular; prosternum evenly punctate; mesosternum without sharp carinae; metasternum with a single fovea between mesocoxae, a small fovea posterior to each mesocoxa, an arcuate fovea anterior to each metacoxa, and median surface without punctures; abdominal ventrite I with 2 small indistinct punctures at anterior corners of intercoxal process, a large irregular fovea nearly as large as metacoxae posterior to each metacoxa, and median surface without punctures; ventrites II– IV unmodified.

Remarks. This species resembles A. atrichos but can be immediately distinguished by its lack of punctures on the median surface of abdominal ventrite I.
