Description.
♀
(
Fig. 257A
). Apterous; body length
1.4–2.2 mm
. Head black, except clypeus and mandible testa- ceous; antenna testaceous; mesosoma black, except lateral margin of apparent pronotum and distal extremity of propodeal declivity testaceous; metasoma brown, except distal half testaceous; legs brown, except tarsi and meso- and metatibia testaceous. In two
paratypes
from
Madagascar
,
18°13.31’S
47°17.13’E
and
18°28.24’S
47°57.36’E
, legs testaceous, except metacoxa partly brown. Antenna (
Fig. 257A
) clavate, thickened; antennomeres of
holotype
in following proportions: 10:3.5:1:3:3.5:3.5:3.5:3.5:3.5:5; antennomeres 1 and 10 longer than broad; antennomeres 3– 9 longer than broad (length/breadth ratio of antennomere
9 in
lateral view: 3.5:3; antennomere 6 longer than broad: 3.5:2); antennomere 2 longer than broad (3.5:2); ADOs present in antennomeres 4–10; antennal toruli contiguous with lateral margins of clypeus. Head rectangular in dorsal view (
Fig. 257A
), slightly longer than broad (20:19), shiny, covered with short and fine setae, finely punctate, unsculptured among punctures; vertex of head flat; frons very convex (
Fig. 258A
); eye (
Fig. 258A
) very small, much shorter than head (3:
20 in
dorsal view); ocelli absent; occipital carina distinct, complete on dorsal region of head, incomplete on lateral regions; frontal line absent; clypeus with ventral margin rounded; temple very long, about 3 × as long as eye (10:3); subocular sulcus absent. Palpal formula 2/2. Propleuron apparently mobile and articulated, hidden under apparent pronotum. Remaining regions of mesosoma completely fused with no sutures separating fused regions; laterally two sutures visible, suture between apparent pronotum and mesothorax and meso-metapleural suture (sutures complete, their upper third or fourth being thiner than rest of sutures). In two
paratypes
from
Madagascar
,
18°13.31’S
47°17.13’E
and
18°28.24’S
47°57.36’E
, and in five
paratypes
from
Madagascar
,
13°07.06’S
49°13.48’E
, lateral suture between apparent pronotum and mesothorax incomplete, upper third being absent. Mesosoma shiny, covered with fine and short setae, finely punctate, unsculptured among punctures; mesosoma cylindric and divided into two regions (anterior flat dorsal region (corresponding to pronotum, mesonotum, metanotum and metapectal-propodeal disc) and posterior inclined region (corresponding to propodeal declivity)); in anterior dorsal region no sutures dorsally visible, except suture separating dorsal region from lateral regions (suture incomplete, being absent in anterior third of dorsal region (probably corresponding to pronotum)) (
Fig. 257A
); propodeal declivity completely surrounded by strong keel separating it from metapectal-propodeal disc and from lateral regions of mesosoma; propodeal declivity finely punctate, unsculptured among punctures, with few transverse striae near apex. Protarsomeres in following proportions: 8:2:2:7:9. Protarsomere 3 produced into hook. Enlarged claw (
Fig. 258B
) without subapical teeth (with tracks of three small teeth), with eight very slender lamellae and many setae on outer side. Protarsomere 5 (
Fig. 258B
) with two rows of 4 + 10 lamellae; apex with four lamellae. Tibial spurs 1/0/1.
