Heterogastrid Bugs

Parathyginus Scudder, 1957

Type species: Heterogaster signifer Walker, 1872

Fauna Portal Genus Number: 738

(after Malipatil 2021): Parathyginus differs from Hyginus in having the triradiate carina of the scutellum usually pale and a very different spermatheca, in the possession of a carina (very faint in some) on the jugum (mandibular plate) making the head appear rounded anteiorly (rather than more pointed head in Hyginus), and lacking in most species the three fuscous equidistant annulations to the tibiae. In Parathyginus spermatheca lacks a terminal bulb and the duct is extremely long, tubular and irregularly coiled, in Hyginus the spermatheca has a terminal bulb and the duct is relatively short and regularly twisted. Parathyginus is related to Artemidorus, in the shape of the head and in the similar type of spermatheca. However, in Artemidorus the hemelytra and abdomen are constricted, the pronotum is narrower and has a deep transverse impression which causes the anterior margin to appear raised.
