February 4th - Global Sciapodinae, #3: Americas and Oriental Region

Heyo, fly folk!

For our third installment in this series, we will discuss the genera in the Oriental Region, which we have not looked at previously. We will then split into those who want to continue practicing on the American genera, which are simpler, and those who would like a challenge and wish to try their hand at the Oriental observations.

Date & Time: 8 PM EST on Sunday, February 4th.

Heteropsilopus nr. ingenuus with scutal stripe

This is a list of observations depicting this species, nothing more.

This species is like H. ingenuus but has restricted wing markings, not connected anteriorly in the male and not extending to the wing apex. More notably, the scutum is grey pruinose (rather than shining green) and has a distinct dark stripe in the center. H. trifasciatus is similar but has 4 bands on the wings with the distal two connected posteriorly, as well as dorsally blue eyes.

Most abundant in SA, but still relatively common in VIC.

Condylostylus pateraeformis Becker species group

Condylostylus is a mostly tropical genus found in the Americas, Africa, and the Oriental Region. The group is most diverse in the Neotropics, but there are many species found in the Afrotropical Region, with most in South Africa or Madagascar, sometimes both. The C. pateraeformis group is easily recognizable with practice and is the most common Condylostylus (and Sciapodinae) found in South Africa.

The C. pateraeformis group is diagnosed in males by the modified wing venation and markings. Vein M1+2 is rather sinuate, bending into cell dm, and the forked vein M1 is almost straight as it goes towards the wing apex, only bending slightly (Fig. 1E, Grichanov 2020). Additionally, males of this species group have long cerci (Fig. 1F) and often have flattened fore tarsi or tibiae (Fig. 1D).

Most of the species require genitalia to confirm, but C. pateraeformis s. str. is easy to diagnose by the strong bend in M1+2 before the fork (compare Fig. 1E to Fig. 2).

February 25th - Global Sciapodinae, #5: Afrotropics
