Primary demodicosis can take the form of pityriasis folliculorum, also known as spinulate
demodicosis, papulopustular perioral, periauricular, or periorbital demodicosis, or a nodulocystic/ conglobate version.
Male pedipalp with RTA, in most species forming a massive spinulate
process which extends to near retro-distal tip of cymbium; short to very large distal retro-lateral tibial apophysis (dRTA) also present; cymbium with small to large field of spinules disto-dorsally.
This new species is small (5.0 mm length) for the species of the region of occurrence, has variable infuscate maculations on the pronotum and elytra, the elytral apices emarginate and spinulate
, and aedeagal morphology (Fig.
Except on segment II, one transverse spinulate
ventral band of 13-16 rows on anterior margin, first 5-6 rows more or less expanded laterally and dorsally than others (Fig.
Corpus bursae elliptical with four short, dentiform signa with sparsely spinulate
, oval basal plates.
Subtribe Embothriinae comprising Embothrium, Telopea, Alloxylon and Oreocallis is recognised with some confidence in the fossil record because its pollen has the synapomorphy of spinulate
sculpturing (Feuer, 1990; Weston & Crisp, 1994; Barker et al., 2007).
DIAGNOSIS: Recognized primarily by the following combination of characters: ovoid body, generally dark chestnut brown dorsum with uniformly distributed, silvery, flattened, reclining setae mixed with simple, semierect setae; antennal segment III shorter than IV; lamellate, semicircular parempodia; excessively enlarged right paramere with a small, blunt-tipped hypophysis; C-shaped endosoma with a spinulate
appendage apically; widely spinulate
bursa copulatrix dorsally with weak, asymmetrical sclerites and posteriorly with a thin, sclerotized structure; and reduced sclerotized ring.
Protergum widest near mid-length, meso- and metaterga widest posteriorly; protergum longer and wider than meso-and metaterga, meso-and metaterga sub-equal in length; protergum with posterotransverse carina weakly developed medially, meso- and metaterga with anterotransverse and poorly developed posterotransverse carinae; terga spinulate
, protergum with numerous small hair-like interior and marginal sensilla; meso- and metatertga with small hair-like sensilla on postero-lateral margins; spiracular openings absent.
Skin of dorsum in males finely tuberculate (not spinulate
), that of females appears smooth but under magnification bears a tuberculation similar to but less dense than in males.
Posterior margin with 3 pairs of stout spinulate
setae, medial setae shorter than the proximal ones; bt / fl > 1.
Endosoma L-shaped, with 2 inner sclerites and membranous, minutely spinulate
Entire length of dorsal face of AntIII spinulate
, 80-90% of length of ventral face bearing 31-50 narrow transverse secondary sensoria (Fig.
