description: Ectomocoris fuscifemoralis Malipatil & Liu, sp. nov.   
(Figs. 14, 15)  
 Type specimens. Holotype male macropterous, Australia, Western Australia, 48 km ENE Norseman, 431-1, at light at night, 19–20.i.1982, B. Hanich & T. F. Houston (WAM). Paratypes (all macropterous): WESTERN AUSTRALIA. 1 male, same data as holotype (WAM); 1 male, same data as holotype except 431-3, on foliage of Eucalyptus (WAM).   
 Description.   
 Macropterous male (Fig. 14)   
 Colouration (Fig. 14): Generally black, thoracic pleura with bluish tinge, abdomen with entire segments II & III and adjoining part of IV, connexiva both dorsally and ventrally with anterior area one third to half (dorsally yellow extending to entire width of connexiva) of segments IV–VII, and most of corium reddish orange. Tarsi brownish, lighter than tibiae. Clavus and inner narrow area of corium bordered by vein Cu adjoining distal 2/3 length of claval suture brown, remainder of corium reddish orange, membrane fuscous excluding a whitish spot located on basal area of AIC.   
Scutellar arch, pronotum shiny smooth black. Head and body including abdomen generally covered with fine short pubescence, with sparse longer bristles obvious on appendages.  
 Structure (Fig. 14): Body small.   
 Head: elongate fusiform, wholly covered with short whitish pilosity and sparse longer bristly setae, dorsal surface with granules. Anteocular region elongate triangular, clypeus near its base distinctly elevated to a knob above mandibular plate. Interocular region with arcuate convex sulcus at posterior border of eyes, a small pit near base. Postocular region almost rounded to neck. Neck with lateral tubercles obvious. Ventral surface of head slightly tumid before eyes. Antennae with all segments cylindrical, with short whitish pilosity and sparse longer setae. Scape thickest, pedicel thinner, then basi-and distiflagellum thinnest. Eyes large, reniform, not reaching ventral margin in lateral view. Ocelli small, conspicuously raised, separated from each other by slightly more than diameter of single ocellus, separated from eye by about the same distance. Labium curved, second visible segment tumid narrowing distally, second and third sparsely covered with longish setae.   
 Thorax: Anterior lobe of pronotum with collar armed with rounded and obvious tubercles at lateral ends, integument smooth, stripes indistinct, except shallow middle long sulcus in basal half. Posterior pronotal lobe arcuately quadrate, integument finely rugulose, with short pilosity, humeri rounded, posterior margin almost smoothly rounded. Scutellum triangular, disc deeply depressed, sides carinate, integument pilose, armed with laterally flattened projected upwards apex. Propleuron with integument sparsely granulose, smoothly pilose, set off from dorsal surface by a carina. Mesopleuron integument minutely granulate, sparsely pilose. Metapleuron with integument sparsely granulate as mesopleuron but granules slightly striate, metapleural sulcus moderately bicarinate and curved, pilose with silvery but not conspicuous hairs posteriorly. All sternites more or less smooth, shiny moderately pilose, in addition with sparse long hairs particularly on disc of venter. Pronotum densely pilose laterad of labial groove. Mesosternum with disc raised, metasternum with disc more or less tumid. Hemelytra slightly exceeding abdomen, laterally narrowly exposing connexiva.   
 Legs: Fore leg with coxa with whitish pilosity; trochanter unarmed, sparsely hairy; femur strongly fusiform, greatly incrassate near base narrowing distally, much thicker than other femora, armed below with rows of bristly setae, also a few irregular granules in row, in addition sparsely pilose laterally and above; tibia cylindrical, more or less straight but apex slightly reflexed, fossula spongiosa present, occupying about half of tibial length; tarsi three segmented, cylindrical, denser short pilosity ventrally. Mid leg with coxa globular, femur only slightly thickened, tibia with short whitish pilosity for whole length, with fossula spongiosa about one third its length. Hind leg with femur almost cylindrical, tibia with brush of seta, denser at apex.   
 Abdomen: In male elongate oval, sternum distinctly carinate in midline, extragenital structure on sternite VII absent (Fig. 14C). Connexivum with golden pilosity as elsewhere on sternum, abdominal sterna and terga entire. Spiracles situated below connexival suture, about halfway between anterior and posterior margin of each segment. Each spiracle postero-ventrally with small spherical to oval shiny impressed spot, also a smaller and irregularly shaped impressed spot close to anterior margin of each abdomen sternum (Fig. 14B). These spots present on corresponding segments on dorsum also but are obscured by hemelytra.   
 Male genitalia (Fig. 15): Median pygophore process with a subbasal indent, medially exteriorly slightly ribbed, gradually narrowed from base to apex and slightly curved apically to point towards right side (Fig. 15A). Parameres subtriangular (Fig. 15B&C), right paramere (Fig. 15C) distinctly broader than left paramere (Fig. 15B). Phallus (Fig. 15D–F) in resting condition with basal plate bridge almost as long as basal plate (Fig. 15D); pedicel nearly straight and slightly shorter than basal plate (Fig. 15E); dorsal phallothecal sclerite broad and flat (Fig. 15D), weekly tumid in middle (Fig. 15E), lateral phallothecal sclerite subrectangular, without process on inner margin (Fig. 15F).   
 Measurements: [of holotype male macropterous]. Body length 10.60; maximum width of abdomen 3.12; length of head 1.82; length of anteocular region 0.77; length of postocular region 0.38; width of head across eyes 1.33; width of interocellar space 0.19; length of eye in dorsal view 0.57; width of eye in dorsal view 0.45; lengths of antennal segments I–IV 0.83 / 2.09 / 2.47 / 1.97 (approximate only); length of visible labial segments I–III 0.57 / 0.95 / 0.57; length of pronotum 2.62; length of anterior pronotal lobe 1.55; length of posterior pronotal lobe 1.02; length of scutellum 1.44; maximum width of scutellum 1.63; length of hemelytra 7.17; length of fore tibia 2.09; length of fossula spongiosa on fore tibia 0.97.   
 Distribution. Australia (Western Australia).   
 Etymology. The species epithet is the Latin adjective fuscifemoralis (meaning ‘having dark femur’), in allusion to the dark femora of the species.   
 Notes. This species, occurring only as macropterous form, resembles E. ornatus (Stål, 1863) macropterous form in general facies, but differs from the latter in the smaller body size (10.6 mm) (vs. 17.2–18.3 mm in E. ornatus), the legs entirely and uniformly blackish as remainder of the body (Fig. 14) (vs. the legs mostly brownish yellow in contrast to the black head and pronotum in E. ornatus (Figs. 26–28)), and the markings on connexiva that are conspicuously darker (Fig. 14).
