Morphological Keys

Stage/Sex Morphological Keys
Female
  • Capitulum broader than long, length x breadth ranging from 0.56 mm x 0.67 mm to 0.72 m m x 0.78 mm
  • Basis capituli with blunt lateral angles a little anterior to mid-length
  • Porose areas oval, about twice their own diameter apart
  • Palps tapering to quite narrowly-rounded apices
  • Scutum slightly longer than broad, length x breadth ranging from 1.20 mm x 1.16 mm to 1.53 mm x 1.45 mm
  • Posterior margin markedly sinuous
  • Eyes fiat, edged dorsally by a few large setiferous punctations
  • Cervical pits convergent
  • Cervical fields slightly depressed, their external margins sharply defined, with numerous large deep setiferous punctations
  • A few large setiferous punctations also present on the scapulae and medially on the scutum, interspersed with numerous interstitial punctations
  • Punctation pattern variable but usually dense and conspicuous
  • Ventrally genital aperture small, U-shaped to broadly V-shaped.

Larva
  • Capitulum much broader than long, length x breadth ranging from 0.097 mm x 0.146 mm to 0.103 mm x 0.160 mm
  • Basis capituli just over three times as broad as long, with lateral angles relatively sharp in African strain but more rounded in Mediterranean strain
  • Anterolateral margins of basis capituli approximately in line with external palpal margins
  • Palps tapering to narrowly-rounded apices, inclined inwards
  • Scutum much broader than long, length x breadth ranging from 0.201 mm x 0.275 mm to 0.215 mm x 0.299 mm
  • Posterior margin a wide, very shallow curve
  • Eyes at widest point, almost fiat
  • Cervical grooves convergent initially, becoming shallow and slightly divergent
  • Ven t rally coxae I each with a large broadly-rounded spur
  • Coxae II and III each with a slight salience only on the posterior margin.

Male
  • Capitulum slightly broader than long, length x breadth ranging from 0.52 mm x 0.56 mm to 0.64 mm x 0.65 mm
  • Basis capituli with acute lateral angles at about anterior third of its length
  • Palps tapering somewhat to rounded apices
  • Conscutum length x breadth ranging from 2.34 mm x 1.49 mm to 2.90 mm x 1.95 mm
  • Anterior process of coxae I inconspicuous
  • In engorged specimens body wall expanded consider ably laterally but less so posteriorly, with a small rounded caudal process
  • Eyes flat, edged dorsally by a few large setiferous punctations
  • Cervical pits comma-shaped, convergent
  • Cervical fields slightly depressed, their external margins delimited by large setiferous punctations
  • Marginal lines long, deep, outlined with numerous large punctations
  • Posteromedian and posterolateral grooves short, broad
  • A few large setiferous punctations present on scapulae and in four more-or-less distinct 'simus' pattern rows me dially on the conscutum, interspersed with numerous interstitial punctations
  • Although the punctation pattern varies considerably it is typically relatively deep and dense
  • Ventrally spiracles somewhat variable in shape but dorsal prolongation usually as wide as adjacent festoon and either gently curved or slightly angled
  • Adanal plates vary from broad and truncated to longer and more pointed posteriorly
  • Accessory adanal plates well sclerotized, sharply pointed.

  • Ventrally with short spurs on posterior margin
  • Anterolateral margins of basis capituli approximately in line with external palpal margins
  • Palps tapering to narrowly-rounded apices, inclined inwards
  • Scutum longer than broad, length x breadth ranging from 0.39 mm x 0.33 mm to 0.46 m m x 0.38 mm
  • Relatively shorter and broader in Mediterranean than in African strain
  • Pos terior margin a deep smooth curve
  • Eyes at widest point, well over halfway back, almost fiat
  • Cervical fields long, narrow, slightly depressed, inconspicuous
