Description
Female holotype (Fig. 1-8)
Colour: pale brown; vertex of head and ante-rior half of mesoscutum orange; posterior half of mesoscutum and scutellum brown; face and legs pale, almost white.
Head with transverse sculpture, face ventral to antennae with scattered slender setae Fig. 1. Inter-antennal protuberance present (Fig. 2). Maxillary palp one-segmented. Antenna (Fig. 3) with radicle short, 1.1 × as long as wide. Scape 4.8 × as long as wide, 7.9 × as long as radicle and 2.5 × as long as pedicel, flagellum with four flagellom-eres; f1 and f2 combined length shorter than f3, f3 2.1 × as long as wide, shorter in length than pedicel plus f1 and f2, and 0.4 × as long as clava; f3 with at least one basiconic peg sensillum basally, clava with 5-6 multiporous plate sensilla (arrowed in Fig. 4), apparently fused to the clava along their lengths; mps 0.1 × length of clava. Claval setae 0.1 × as long as clava; clava with an apparent partial suture approximately 1/3 along its length from the base (arrowed in Fig. 3). Clava 3.5 × as long as wide, obliquely truncate api-cally. Lateral lobe of mesoscutum (Fig. 5) with one seta; mid lobe with two pairs of setae and faint reticulate sculpture; scutellum with two pairs of setae. Fore tibial spur 0.7 × length of basitarsus. Fore wing (Fig. 6) hyaline, with faint infuscation basally, 3.3 × as long as broad; longest seta of posterior marginal fringe 0.5 × width of wing; marginal vein with row of six long setae along anterior margin; discal setation relatively uniform. A single row of small campaniform sensilla on dorsal surface of basal cell, just posterior to submarginal vein (Fig. 7). Hind wing 7.0 × as long as broad, posterior marginal fringe 1.2 × width of wing; discal setation arranged in 2-3 rows. Ovipositor (Fig. 8) 3.6 × as long as hind basitarsus.
Male
Unknown.
Diagnosis
Cales motterni sp.n. can be distinguished from other species in the genus by the following combination of characters: antennal clava with several multiporous plate sensilla attached throughout their lengths; each side lobe of mesoscutum with one seta; fore wing with setae rather evenly distributed; a single row of small campaniform sensilla on dorsal surface of basal cell, just posterior to submarginal vein.
Etymology
The species is named for Dr Jason Mottern, formerly of the University of California, Riverside, USA in recognition of his major contribution to our understanding of this unusual genus.
Distribution
TAIWAN: Xindian District, Wulai.
Biology
A primary endoparasitoid of Bemisia pongamiae ( Hemiptera : Aleyrodidae ). No parasitoids have been recorded to date from this host ( Noyes 2015; Shih et al. 2008).
Taxon discussion
The single female paratype is identical in all respects to the holotype. Cales motterni is an unusual species in several ways. Morphologically, the clava shows vestiges of having developed from a 2-segmented condition. This, plus the assumed plesiomorphic state of the wing setation, suggests it may be the most morphologically basal species known in the genus.
Cales motterni sp.n. is the only species of the genus currently known from Taiwan.
