Hesus subarmatus STÅL 1873


Hesus subarmatus STÅL 1873 ( Fig. 5, 13, 14 View Fig , 23, 28 View Fig ; photo 7)

Described from Surinam. As it is unclear from the description if it was based on a single or more females, a pinned specimen with following labels: «Surin.» / «Thorey» / « subarmatus Stål » / «typus» (may have been attached later by a curator?) in the collection of the Naturhistoriska Rijksmuseet Stockholm has therefore been designated as lectotype and labelled accordingly, when studying the collection years ago. This designation was not yet published and is done herewith.

Habitus, colouration of body, antennae, and legs as well as the structures on anterior pronotal lobe of Hesus subarmatus are very close to those of H. mexicanus (photo 7). Therefore it is necessary to reexamine specimens identified as H. subarmatus in collections to verify their true identity. As the usually reliable distinctive character – the presence of two (1+1) converging median ridges on posterior pronotal disk--are sometimes weakly developed, male specimens can be identified by their genitalic structures; however, single females may not be clearly assigned to one of these taxa.

Spiracles II-V ventral, VI lateral and visible from above, VII dorsolateral, VIII terminal. Terminal segments as fig. 13, 14. Pygophore dorsally more sloping posteriorly, with larger tongue-like dorsal sclerite (fig. 28); parameres wider fig. 23.
