description: Carpophilus (Myothorax) imitatus sp. nov.
(Fig. 7)
Type material. Holotype ♁, Australia, New South Wales, Kyalite, Feb 2018, from pheromone trap in pistachio orchard VAITC No. 8602 (VAIC).
Paratypes - New South Wales: 1♁ same data as Holotype, VAITC 8601 (VAIC); 2♀ same data as Holotype, VAITC 8603, 8604 (VAIC); S outh Australia: 1♁ Pinnaroo, Feb 2018, from pheromone trap in pistachio orchard, VAITC 8225 (VAIC); 3♀ Pinnaroo, Feb 2018, from pheromone trap in pistachio orchard, VAITC 8606, 8607, 8608 (VAIC); 2♀ Paringa, 10 Feb 2016, from pheromone trap in almond orchard, VAITC 6739 & 6740 (VAIC).
Diagnosis
A small species around 2.0– 2.4 mm in length, uniformly brown, with fine pitting on pronotum; prosternum distinctly pitted and hypomeron weakly pitted. Male specimens with metatibia constricted along basal ¼ to 1/3; male paramere roundly truncate at apex.
Description
(n= 10 specimens examined, 3 ♁, 7 ♀)
Body, length (2.0– 2.4 mm); lateral margins parallel to subparallel; dark (chestnut) brown, unicolorous; setae on body, golden.
Head. Length of 3 rd antennomere 1x (or less) length of 2 nd antennomere; male mandibles symmetrical.
Thorax. Prothorax. Shape of pronotum laterally slightly convex (subparallel), anterior angles rounded, posterior angles not toothed but more or less forming a right angle with a rounded apex; width of pronotum around 1.3 to 1.5x times length; pitting on disc of pronotum relatively fine, usually separated by around one diameter but more widely separated along the medial line, particularly in the posterior half; prosternum with distinct pitting, lateral margins very slightly divergent towards posterior margin (Fig. 7C); prosternal process, slightly narrower at the base than the apex, lateral margins slightly concave, apex only slightly expanded, apical margin rounded; hypomeron only weakly punctate to rugulose. Mesoventrite and metaventrite. Mesosternum rugosely pitted, no medial carina present; metepisternal axillary space relatively distinct, axillary line straight or slightly curved, reaching around ¼ length of metepisternum. Legs. Metatibia of males constricted along basal ¼ to 1/3 and then distinctly expanded towards apex (Fig 7D), as in C. truncatus.
Abdomen (Fig. 7F). Genitalia. Male paramere in lateral view with dorsal margin convex and ventral margin evenly concave, narrowing towards apex, numerous fine setae along ventral apical margin, base of dorsal margin with a small nodule; in dorsal view, with outer lateral margin slightly convex, lateral inner (mesal) margin slightly curved, concave around mid-length to pre-apically, apex of paramere slightly oblique, rounded particularly on outer angle, appearing roundly truncate. Female internal genitalia was not examined in this study.
