Thryptomenomiris View in CoL , new genus Figures 7–9, 35–37; map 2; plate 1
TYPE SPECIES: Thryptomenomiris kalbarri , new species.
DIAGNOSIS: Recognized within the Melaleucoides genus group by the small size, the apparent absence of a secondary endosomal strap (fig. 7; 31-3), the unique conformation of the left paramere, with a greatly elongate, medial, apical process (fig. 7; 56-2), and the female vestibulum with large, nearly symmetrical medial plates (fig. 7; 74-1). Also recognized within the Melaleucoides genus group by possessing only the ventral endosomal process. Easily confused with Harpagophylus calytrix , Melaleucoides akaina , and M. pileanthicola on the basis of small size and reddish markings on a pale background. Easily distinguished from Melaleucoides akiana by the absence of the ventral endosomal process in that species, from Harpagophylus spp. by their possession of both ventral and dorsal endosomal processes, and from all of those taxa by the presence of a secondary endosomal strap and the distinctive structure of the left paramere in Thryptomenomiris .
DESCRIPTION: Male: Body moderately elongate, parallel sided; small, mean total length 2.44–2.79, mean width pronotum 0.77–0.92. COLORATION (pl. 1): Pale with some brownish or reddish areas. SURFACE AND VESTITURE (fig. 8C): Dorsum with suberect or reclining black setae and some sericeous or woolly setae. STRUCTURE: Head (fig. 8A): Somewhat projecting; interocular space moderate; eyes leaving gena moderately exposed in lateral view. Antenna: Segment 2 weakly tapering, more slender at base; antennal fossa with ventral margin 1 diameter above ventral margin of eye. Labium: Just reaching onto abdomen. Thorax: Pretarsus (fig. 8D): Parempodia fleshy, recurved, lyriform; pulvilli absent. GENITA- LIA (figs. 7, 8E, F, 9): Endosoma: Base short, curving, C- or J-shaped; body without torsion, primary strap ventral to secondary gonopore, apically greatly elongate, without ornamentation; spinelike, elongate process near gonopore on ventral surface present, recurved toward base of endosoma; second- ary gonopore seen laterally in lateral view of endosoma. Phallotheca: Smoothly curving or nearly straight on dorsal margin; ventral surface with or without a projecting keel; apex simple. Left Paramere: Vertical; shaft at right angles to body; in dorsal perspective (fig. 8F), not exceeding margin of pygophore; in lateral perspective (fig. 8E) covering limit- ed extent of lateral surface of pygophore; body more or less quadrate; apex medially broadly rounded to weakly quadrate; apex posterolaterally with a greatly elongate projection (figs. 7, 8F, 9); anterior process slender and cylindrical 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 short, clawlike, decurved.
Female: Slightly more ovoid than male; small, mean total length 2.52–2.82, mean width pronotum 0.80–0.93. COLORATION (pl. 1): As in male. STRUCTURE: Head (fig. 8B). GENITALIA (fig. 7): Posterior wall laterally with distinct crescent-shaped interramal sclerites; posterolaterally with a distinct swelling covered with microtrichia; longitudinal fold on either side of midline along part of length; interramal lobes roughly symmetrical, erect, and not ornamented with spicules or with a very few; vestibulum with medial plates sclerotized and readily visible, large, nearly symmetrical, with sclerotized guide structure present as caplike structure with internal differentiation.
ETYMOLOGY: Named for the host genus, Thryptomene (Myrtaceae) , in combination with Miris ; gender masculine.
