Paramblynotus ruficeps Cameron, 1910

Paramblynotus ruficeps Cameron, 1908: 300 , Oi; Borneo; BMNH (HTOi, main coll.).

* Allocynips isosceles Weld (1922: 331 , Oi ♀); Singapore; USNM (HT ♀, no. 24 379, 3 PTOi), combination by Weld (1930:137), and synonymy by Ronquist (1995a: 37).

FEMALE: Length 2.6–3.8 mm. 1mt/2– 5mt 5 0.55. Body usually yellowish brown to dark brown, mesosoma and/or head sometimes black. Antenna 13-segmented and dark brown. Wings clear, except marginal cell of forewing deep ferruginous.

MALE: Length 1.8–2.5 mm. Antenna 14- segmented.

The generally yellowish to brown body of P. ruficeps color resembles species of the annulicornis species complex, but P. ruficeps lacks a pale ring on the antenna, the median frontal carina is only weakly present between antennal sockets, and the macula of the forewing is only limited to a marginal cell. Darker individuals of the species can be more easily confused with lighter individuals of its sympatric species P. punctulatus . Nonetheless, the two species can be distinguished relatively easily. P. ruficeps has clear wings with a ferruginous marginal cell, the angle between Rs and 2r is less than 90 °, and the marginal cell is about 2.5 times as long as wide. P. punctulatus has relatively evenly smoke-tinted wings, the angle between Rs and 2r is distinctly larger than 90 °, and the marginal cell is about 3.3 times as long as wide.
