Melaleucoides systenae View in CoL , new species Figure 29, map 5, plate 4
DIAGNOSIS: Males recognized in most specimens by the castaneous pronotum anterior lobe, scutellum, and posterior half of the endocorium; phallotheca with a very broad reflexed flange on the dorsal margin; left paramere very broad apically; endosoma with a ventral process associated with the secondary gonopore and no denticles distad of the gonopore. Except for rather variable coloration with the taxon, M. systenae is not easily confused with any other known species of Melaleucoides .
DESCRIPTION: Male: Body weakly to distinctly ovoid; mean total length 3.23, mean width pronotum 1.22. COLORATION (pl. 4): Head: Mostly dark with pale gula and posterior head margin; scapus unicolorous dark; pedicellus black at extreme base, remainder pale; labium generally infuscate, heavily so apically. Thorax: Pronotum usually with dark anterior lobe and contrasting lighter-colored posterior lobe; scutellum entirely dark; clavus pale, corium pale on anterior half, dark posteriorly; markings on cuneus present as a contrasting white basal fascia; membrane fumose, veins white or pale; hind femur nearly unicolorous dark; hind tibial spines dark with very small dark bases. Abdomen: Venter unicolorous dark. SURFACE AND VESTITURE: Dorsum with suberect or reclining black setae, without sericeous or woolly setae. STRUC- TURE: Head: Weakly projecting; interocular space relatively large; eyes leaving gena broadly exposed in lateral view. Antenna: Segment 2 weakly tapering, more slender at base; antennal fossa with ventral margin at ventral margin of eye. Labium: Just reaching onto abdomen. Thorax: Pretarsus: Pulvilli present, flaplike, covering about one third of ventral claw surface. GENITALIA (fig. 29): Endosoma: Primary strap apically elongate, angled dorsal relative to body of endosoma, without ornamentation; secondary endoso- mal strap fused with primary strap proximal to secondary gonopore, reaching only to level of secondary gonopore; spinelike elongate process arising near gonopore on dorsal surface absent; spinelike, elongate process near gonopore on ventral surface present, relatively short, recurved toward base of endosoma; bladderlike process distad of secondary gonopore present, elongate, and paralleling primary endosomal strap; secondary gonopore seen frontally (facing up) in lateral view of endosoma. Phallotheca: Nearly erect; dorsal surface with a curving, posteriorly directed, platelike projection; ventral surface with a projecting keel; apex simple. Left Paramere: Shaft at right angles to body; body spoon shaped; apex quadrate; anterior process triangular in lateral view; posterior process in the form of a short, straight, fingerlike projection; base of posterior process without conspicuous shoulder. Right Paramere: Body short and broad, lanceolate; apex with short fingerlike process.
Female: Slightly more ovoid than male; mean total length 3.51, mean width prono- tum 1.32. COLORATION (pl. 4): Paler than male, more strongly reddish, without the nearly castaneous quality of most males. GENITALIA: Posterior wall laterally with distinct crescent-shaped interramal sclerites; posteriorly without a sclerotized transverse band; posterolaterally with a distinct swelling covered with microtrichia; longitudinal fold on either side of midline along part of length; posterior margin of posterior wall without spicules and not reflexed dorsally; interramal lobes present and asymmetrical, reclining, overlapping, and heavily ornamented with spicules; vestibulum with medial plates sclerotized and readily observed, small, nearly symmetrical, triangular, with sclerotized guide present as short heavily sclerotized tube on left side.
