Identification of species in other subfamilies in the family Pergidae

There are several subfamilies in the family Pergidae that are not dealt with in other notes pages - Pergulinae, Styracotechyinae, Pteryperginae, Phylacteophaginae and Philomastiginae.

The matrix below shows diagnostic features to aid recognition of each of these subfamilies.

Styracotechyinae

This subfamily contains only one species - Styracotechys dicelysma Benson

Female:
size: small (4mm long)
head: broad head, eye covers most of its length viewed dorsally; brownish-black with mouthparts and clypeus brown
antennae: 14 segments; black with 4 basal segments brown; short, flagellum about half breadth of head; inserted close to hind margin of clypeus; each flagellar segment with small pecten beneath
thorax and abdomen: orange with side lobes of mesonotum, scutellum and abdomen from middle of 4th segment blackish-brown
wings: hyaline; costa yellow; stigma and rest of venation brown
legs: yellow, except for blackish-brown hind tibiae and tarsi; with long preapical tibial spurs on middle and hind legs; apical tibial spurs exceptionally long, in hind legs longer than length of following 3 tarsal segments together

Male:
not yet formally described but Schmidt et al (2006) show a photo displaying following features -
antennae: 14 segments; blackish-brown; bipectinate and exceptionally long
thorax and abdomen: blackish-brown
legs: coxae, brown and white in all legs; femora, brownish-black, with apex white in fore and mid legs and base white in hind legs; tibiae and tarsi, white in fore and mid legs, blackish-brown in hind legs

The remaining subfamilies - Pergulinae, Pteryperginae, Phylacteophaginae and Philomastiginae - all have more than one species. The matrices below are designed to aid identification of their genera and species.

This is a workbook page … a part of our website where we record the observations and references used in making species identifications. The notes will not necessarily be complete. They are a record for our own use, but we are happy to share this information with others.
