Description.

Male holotype (QM T238476, RL2433b): Body length 16 mm, forewing length 12.7 mm, head width 5.6 mm.

Structure: Inner orbits of eyes diverging above; head wider than long; clypeal protuberance in profile 0.53 × eye width; mandible with weak subapical tooth; F1 equal to combined length of next 1.5 flagellomeres; F1 0.63 × as long as scape; F2 0.82 × as long as F3; F3-F10 1.3 × as long as wide; last flagellomere 1.14 × as long as F1, marginal cell length 0.81 × distance from apex of cell to wing tip; cu-v of hind wing 1.77 × length of second abscissa of M+Cu; S5 with apicomedial emargination very shallow, 6.3 × as wide as deep; S6 with apicomedial emargination circa four times as wide as deep.

Genitalia: penis valves shoulders not extended; volsella elongated, with 6 long setae (Fig. 21H ); gonocoxa laterally with numerous small setae; apex of gonocoxa ventrally without process (Fig. 21H ); outer gonostylus long and slender with fine setae on inner surface; inner gonostylus circa as long as outer gonostylus, but more robust, with numerous long setae (Fig. 21G ); S7 (Fig. 21E ); S8 apex almost tridentate middle process, emarginate with long setae (Fig. 21F ).

Pubescence: Head black on labrum, clypeus and genae, orange brown around ocelli and vertex; scutum, scutellum, metanotum and metapostnotum orange-brown; mesosoma laterally and ventrally black; fore leg and metasoma with black hairs only; S4 apicomedial area with small patch of ventrally directed black bristles, S5 with two longitudinal semi-parallel patches of posteriorly directed bristles, S6 almost bare.

Colouration: Integument black, apart from: scape yellow patch below; labrum yellow with large black marks in dorsolateral corners; clypeus yellow; supraclypeal area with yellow triangle; paraclypeal area yellow; mandible yellow at base; proboscis dark brown; wings dark brown.

Female allotype (AM K470082): Body length 19 mm, forewing length 15.6 mm, head width 6.7 mm.

Structure: Inner orbits of eyes diverging above; head wider than long; clypeal protuberance in profile 0.75 × eye width; mandible with weak subapical tooth; F1 equal to combined length of next 2.7 flagellomeres; F1 0.88 × as long as scape; F2 circa as long as F3; F3-F10 slightly longer than wide; last flagellomere 0.57 × as long as F1; marginal cell length 0.82 × distance from apex of cell to wing tip; cu-v of hind wing 1.27 × length of second abscissa of M+Cu; S6 with distinct blunt posteriorly projecting subapical lobe, visible as spine when viewed laterally (Fig. 21L ).

Pubescence: Head black on labrum, clypeus and genae, orange brown around ocelli and vertex; scutum, scutellum, metanotum and metapostnotum orange-brown; mesosoma laterally and ventrally with black hairs only; fore leg with legs and metasoma with black hairs only.

Colouration: Integument black to dark brown; legs and sterna brown; scape black; labrum black; clypeus dark brown with tiny yellow ventro- and dorso-median dots; supraclypeal area with small yellow triangle; paraclypeal area black; mandible with tiny yellow mark at base; proboscis dark brown; wings dark brown.

Flower records.

At three different locations in 2017, male territorial behaviour was observed above water with native Water Hyacinth, Monochoria australasica ( Pontederiaceae ). Figure 21O .

Distribution.

Figure 21I .

Etymology.

The specific epithet refers to Australian female carpenter bees Xylocopa (Koptortosoma) sp., because of its superficial resemblance with respect to hair and wing colouration.
