Aradoleptus birmanus nov.sp. ( Figs. 11-12 , photo 5)

H o l o t y p e: Submacropterous female in a piece of Burmese amber from " Kachin State " in Myanmar (Burma), legs and antennae complete and bent ventrally ; the exuvia of the last moulting stage is still attached to the specimen obscuring partly ventral segments. It is designated as holotype and labeled accordingly.

D e s c r i p t i o n:

H e a d: Longer than wide (30/25), clypeus subparallel, dorsally not carinate, apex rounded reaching ½ of antennal segment II; antenniferous lobes widening anteriorly, margins serrate; antennae 1.68x as long as width of head, segments I-III cylindrical, I shortest, II longer, III and IV of equal length, the latter fusiform; length of antennal segments I/II/III/IV = 7/10/13/13; eyes oval; postocular lobes not reaching outer margins of eyes, roundly converging posteriorly, lateral margins granulate; vertex beset with dense granulation.

P r o n o t u m: Trapezoidal 1.63x as wide as long (36/22); paranota narrow, lateral margins finely serrate, sinuately converging anterolaterally, anterolateral angles blunt not reaching level of anterior margin; disk with four carinae, the two median ones lower, longer and straight, the sublateral ones more prominent, shorter and converging anteriorly.

S c u t e l l u m: 1.5x as long as wide, lateral margins carinate, apex acute; disk with a median elevation on basal half, depressed posteriorly.

H e m e l y t r a: Corium nearly reaching apex of scutellum, posterolaterally angularly rounded; disk with 2 veins; membrane hyaline reaching half of mtg VI with four faint veins, surface wrinkled.

A b d o m e n, v e n t e r and l e g s as generic description.

M e a s u r e m e n t s: Length 4.0mm, including exuvia 6.25mm; length of antennae 1.05mm; width of corium 1.0mm; length of abdomen 2.25mm, width across tergite V 1.55mm.

E t y m o l o g y: Refers to Birma, the former historical English name for Myanmar.
