Ansifera asetosa sp. n.

( Fig. 4 View Fig A-B)

Diagnosis:

This is the only species of Ansifera in which the translucent sensilla on the male antennae are leafshaped ( Fig. 4A View Fig ), the wing membrane is devoid of setae, and CuA2 is practically absent.

- B: terminalia, ventral view. Length of scale bar = 0.05 mm.

Description:

Male. Body length: 0.9-1.0 mm. Head: Postfrons asetose. Eye bridge 3-4 ommatidia long, short- er laterally than dorsally. Postocular bristles absent. Neck of fourth antennal flagellomere longer than node; node with 1 complete and 1 incomplete crenulate whorl, crenulation poorly developed; translucent sensilla small, irregularly leaf-shaped, arising from 1 to 3 basal pores ( Fig. 4A View Fig ), or such sensilla absent. Maxillary palpus short, basal segment slightly swollen, second segment attached subapically on first, apical segment asetose, slightly longer than preceding segment.

Wing: Costal break missing. ApicR1 1.5 times the length of Rs. CuA2 practically absent. Dorsal setae only on R1. Alar setae absent.

Preabdomen: Terga 2-5 with single lateral setae, terga 6-8 with few lateral and dorsal setae. Terminalia: Fig. 4B View Fig . Ventral emargination of gonocoxites shallow, dorsal transverse bridge projecting beyond ventrobasal margin, the latter partly reinforced. Gonostylus comparatively thick, not flattened. Ejaculatory apodeme longer than tegmen, apical extension membranous. Tegmen slightly tapered toward apex, the latter membranous, truncate.

Female and immature stages. Unknown.

Distribution and phenology:

Ansifera asetosa is only known from the type locality, which is identical to that of the previous species. One of the two specimens was captured over moist, rotten wood, the other specimen was caught elsewhere in forest.

Etymology: The name is Latin, meaning asetose, referring to the bare wing membrane characteristic of this species.

JASCHHOF (in NHRS) . Paratype: 1 male, same locality, 8-21 March 1997, by Malaise trap, H. HIPPA , M. JASCHHOF & B. VIKLUND (in SDEI).
