(Plate 117D)
Pseudogonatopus sarawakensis Olmi 1984: 1241.
Description of Female. Apterous; length 2.6–4.2 mm. Head brown-reddish, except mandible, clypeus and anterior region of face yellow; occasionally head mostly dark or black; antenna brown, except segments 1–2 yellow; mesosoma testaceous-yellow; occasionally scutum yellow; occasionally scutellum and lateral regions of metanotum darkened or blackish; occasionally mesopleuron and metapleuron darkened; petiole black; metasoma black, with reddish nuances; legs testaceous. Antenna clavate, with rhinaria on segments 9–10; antennal segments in following proportions: 10:7.5:27:11:10:10:9:8:8:12. Head excavated, shiny, smooth, weakly alutaceous; POL = 7; OL = 4; OOL = 12. Palpal formula 2/2, 3/2, 4/2. Pronotum crossed by strong transverse impression, shiny, weakly granulated. Metanotum shiny, transversely striate, laterally protruding; lateral protrusions rounded. Mesopleuron transversely striate. Metathorax + propodeum shiny, smooth, unsculptured, with numerous transverse striae on posterior surface and metapleuron; occasionally disc of metathorax + propodeum with slight track of median longitudinal furrow. Meso-metapleural suture obsolete. Protarsal segments in following proportions: 15:3:4:15:23. Enlarged claw (Plate 117D) with one large subapical tooth and one row of five–seven lamellae. Segment 5 of protarsus (Plate 117D) with two rows of 14–20 lamellae; distal apex with 3–8 lamellae. Tibial spurs 1/0/1.
Male. See Remarks.
Material examined. Types: holotype ♀: MALAYSIA: Sarawak, Gunung Mulu, 17.IX–23.X.1977, D. Hollis leg. (BMNH). Paratype: same locality label as holotype, 1♀ (BMNH).
Hosts. Unknown.
Distribution. Malaysia (Sarawak).
Remarks. In BMNH there is a series of Gonatopus males with palpal formula 3/2 or 4/2 collected in Malaysia, Sarawak, Gunung Mulu National Park. They may be the opposite sex of G. sarawakensis (Olmi) or G. malesiae (Olmi), whose females were collected in the same site by the same collectors. The above males were divided by Olmi (1984) into two groups (A and B), according to the following characters: A: distal apex of paramere rounded; notauli posteriorly joint; B: distal apex of paramere pointed; notauli posteriorly separated. With no rearings and/or DNA studies, it is impossible to attribute the above males to one of the above two species, G. sarawakensis and G. malesiae. The descriptions of the above males is the following: fully winged; length 1.4–2.5 mm. Head black or brown; antenna brown or partly testaceous; mesosoma and metasoma black or brown; legs yellow. Antenna filiform; antennal segments of male A in following proportions: 5:5:9:7:7:7:8:7:6:10; antennal segments of male B in following proportions: 5:6:9:9:8:8:8:8:8:11; in both males, antennal segment 3 more than three times as long as broad (male A: 4.0; male B: 3.66). Head dull, hairy, rugose; occipital carina absent; temple short, distinct; POL = 5; OL = 2; OOL = 2.5; greatest breadth of posterior ocelli longer than OL (3:2). Palpal formula: 3/2, 4/2. Scutum dull, hairy, punctate. Notauli complete, posteriorly joint (male A) or separated (male B); in male B, minimum distance between notauli shorter than greatest breadth of posterior ocelli (2:3). Scutellum and metanotum shiny, smooth, hairy, punctate, unsculptured among punctures. Propodeum reticulate rugose. Fore wing hyaline, without dark transverse bands. Dorsal process of paramere (Plate 117B, C) long and broad, with distal apex rounded (male A; plate 117B) or pointed (male B; Plate 117C). Tibial spurs 1/1/2.
