Asynapta suzzae  sp. n.

( Fig. 4View FIGURE 4 C –D)

Diagnosis. Asynapta suzzae  is a large and strongly pigmented species of Asynapta  . Male genital characters specific to this species are as follows. The gonostylus has a strong swelling ventrosubapically that bears 2 long bristles (Fig. D, ↓) (each 1 additional bristle is inserted dorsally and on the outer margin of gonostylus). There is the general tendency in Asynapta  that gonostyli are swollen ventrosubapically, but in A. suzzae  this feature is very obvious. Furthermore, the medial gonocoxal bridge bears a pointed, glabrous protuberance (Fig. D, ↓). These two characters in combination are absolutely diagnostic.

Asynapta suzzae  is generally similar to A. thuraui Rübsaamen  ( Jaschhof & Jaschhof 2013: fig. 161), one of the more common and widespread Asynapta  in Europe. However, the gonostyli of A. thuraui  lack a subapical swelling, and the parameres are much more slender and sulcate apically.

Other male characters. Body size 1.8 mm. Head. Eye bridge 9–10 ommatidia long. Antennae broken, maximally 16 flagellomeres retained. Neck of fourth flagellomere as long as node. Circumfilum and palpus as typical in Asynapta ( Jaschhof & Jaschhof 2013)  . Thorax. Metepisternum asetose. Wing. Vestige of M present at wing margin. Legs. Claws and empodia as typical in Asynapta  . Terminalia ( Fig. 4View FIGURE 4 C –D). Ventral emargination of gonocoxae with obscure outline (Fig. D). Common shaft of gonocoxal apodemes slightly bilobed anteriorly (Fig. D). Aedeagus head subquadratic. Parameres flexible, not sulcate, apices pointing posterolaterally (Fig. C).

Etymology. This species is named after Suzanne („Suzza“) Petersson, Färjestaden, Öland. Ms Petersson emerged the winner of a public panel game addressing entomology, which was arranged by Station Linné on September 26, 2014. The win enabled her to propose a new species name of her choice.

Types. Holotype. Male (CEC 69), Sweden, Öland, Mörbylånga, Gamla Skogsby (Kalkstad), bushy meadow, 27 June 2014, sweepnet, M. & C. Jaschhof (in NHRS). Paratype. Male (CEC 70), same data as the holotype.
