(Figs. 1, 14 17) 
Type Locality: Philippines, Mindanoa, Surigao. 
Type Material: Holotype: Female [Baker Collection, USNM].

“javelin”, and is a reference to the elongate spine on the scutellum of 
this species. 
Diagnosis: 
This species can be immediately recognized by the prominent 
spine at the apex of the scutellum (Figs. I, 15). The apex of the 
scutellum is truncate in K. eumenidarum (Fig. 7) and K. megalaspis 
(Fig. 11).

Female: Length, 5.4 mm. Black, except tegula and flagellum 
brown, mandible reddish-brown, apex of foretibia and spur, and 
tarsi yellow; wings hyaline, veins darkened. 
Head: length of malar space 0.34 eye height; OOL 0.95 POL; 
maximum width of scrobe 0.56 head width; head transverse, width: 
height = 1.17; inner and outer orbits costate, costae convergent on 
clypeus; scrobal cavity deep and wide, extending below lower ocular 
line and delimiting clypeus and supraclypeal area; clypeus trans- 
verse, width:height = 1.31, polished and covered with long setae; 
clypeus not delimited by sutures, upper margin indicated by a faint 
line, tentorial pits distinct, lower margin weakly emarginate; ocular- 
ocellar region with costae radiating from posterior ocellus; vertex 
with strong costae at posterior margin; supraclypeal area glabrous, 
height 0.51 clypeus height; lateral wall of scrobe merging smoothly 
with face; lower tooth of mandible pointed at apex; base of mandi- 
ble with weak punctures; labio-maxillary complex short. Antenna;

funicular segments subequal in length (18 versus 14,15,17,16,15, 
1 5, 1 3;F 1 — F7); pedicel 0.21 scape length; anellus 0.43 length of FI; 
FI elongate, remaining flagellomeres transverse; clava 0.25 length of 
funicle.
