Description of worker ( Figs. 5-8 View Figures 5 - 8 )
Measurements: TL 19.45, HL 2.81, HW 2.55, CI 91, SL 2.60, SI 102, MandL 3.54, MI 126, MLO 3.64, PW 2.03, ML 5.04, PetL 1.35, PetH 0.88, HFL 3.22, MtL 4.16, EL 1.40, EW 0.94, EI 55, MOW 0.11 (n=1).
In full face view, posterior margin of head straight; scape exceeds posterior margin of head by at least width of scape; ocelli present; frontal lobes broad, covering antennal sockets; frontal carinae short, as long as about twice width of scape, diverging; clypeus narrowly inserted between frontal lobes; triangular labral lobe present; eyes extremely large, ovate, occupying the anterior lateral margin of head; mandibles converging rather abruptly from attachments; head irregularly reticulo-punctate; antennal scape with sparse, short erect and suberect hairs.
In lateral view, mesosoma long and cylindrical; front coxa well separated from mid- and hindcoxae; front coxa long but distal end not reaching midcoxa; promesonotal suture deeply impressed; metanotal groove obsolete; dorsal face of propodeum very long; propodeal declivity not bounded by lateral carinae; metapleural gland orifice opening laterally, not protected by guard hairs; petiole longer than tall; anterior subpetiolar process triangular; gaster long; sting present and functional; tarsal claws with median tooth.
In dorsal view, irregular striae subparallel, but diverging posterior fourth of pronotum; irregular striae subparallel on mesonotum; propodeum coarsely punctate; petiole longer than broad; petiole coarsely punctate dorsally and laterally; first and second gastral tergite coarsely punctate over underlying punctulation.
Sparse short hairs on body. Body black; mandibles and antennae chocolatebrown; legs yellowish chocolate-brown.
Comparative Note: This specimen is superficially similar to H. venator chapmani Donisthorpe, 1937 which Donisthorpe (1937) considered a black variety of H. venator F. Smith, 1858 , albeit with sculpturation similar to H. v. rugosus Mayr, 1862 . The key (see below) summarizes the morphological differences with a non-type specimen of H. v. rugosus . Unfortunately, the holotype of H. v. chapmani cannot be located at the MCZC, AMNH, USNM, or BMNH, precluding a direct comparison and a confident determination (DEMG, personal observation; Natural History Museum Data Portal. 2016).
Etymology: This species is named after my mentor and colleague, Dr. Gary D. Alpert, a true friend who hosted all my visits to Cambridge, MA, USA. Gary’s fortuitous visit to Naga City and Mt. Isarog firmly redirected my research interest from spiders to ants.
