Morphological Keys

Stage/Sex Morphological Keys
Female
  • The female features a scutum with an approximately equal length-to-width ratio, an often rugose surface, and few, large punctations
  • The genital operculum is elongately triangular in outline, gradually depressed in profile, and is surrounded by a narrow, raised integumental fold.

Male
  • The male is generally larger than H. anatolicum, featuring a flat body that is as broad as long (measuring between 4.5 x 4.2 mm and 5.7 x 5.7 mm) due to considerable lateral body extensions beyond the less chitinous scutum
  • The scutum bears a few large, shallow, scattered punctations with others rare or absent, a distinct white median festoon (parma), and 11 total festoons, of which only five have grooves on the scutum
  • The scutal grooves are generally shallow: cervical grooves are broad, posteriorly divergent, and continuous with postero-lateral grooves
  • The median groove is narrow and superficial
  • Lateral grooves are poorly developed, hardly visible anteriorly, and limited to the posterior third
  • And a deep, narrow posteromedian groove extends from the parma to the scutal midlength, bounded by converging ridges and deep, rugose paramedian grooves
  • Ventrally, subanal shields are displaced laterally, adanal shields feature a middle inner projection, and six to eight (sometimes poorly developed) scutes are present
  • The 1.3 mm capitulum features short palps with sub-equal articles II and III that are as broad as they are long
  • Article II has a blunt dorsal retroverted prominence and a wider proximal portion, while article III has a lateral projection
  • Lastly, the segments of the last three pairs of legs are significantly stronger than those of the first pair.
