Description: ♂♂, ♀♀. Medium-sized to large (body length ♀♀ (including subgenital plate) 115.5–172.0 mm, ♂♂ 82.0–103.0 mm), slender and elongate Haplopodini, ♀♀ brachypterous, ♂♂ brachypterous or with well developed alae. Body ± cylindrical in cross-section. Colouration of ♀♀ various shades of brown, straw and grey, rarely greenish. ♂♂ rather colourful insects and sometimes multi-colorous but mostly green or greenish brown; body surface glabrous. Head indistinctly longer than wide and globose, vertex ± convex and distinctly bi-spinose or bicornute; the dextral spine larger than the sinistral. Antennae filiform in ♀♀ and considerably thickened and robust in ♂♂; in ♀♀ almost as long as head and complete thorax combined, in ♂♂ reaching at least to abdominal segment III. Pronotum about as long as head and with a ± distinct pair of anterior tubercles or spines; otherwise ± tuberculose. Mesothorax elongate and parallel-sided, at least 2x longer than head and pronotum combined. Mesonotum in ♀♀ rather irregularly and to a variable degree armed with granules or spiniform tubercles, in ♂♂ armed with a variable number of distinct spines. Mesopleurae smooth in ♂♂ and with a longitudinal row of tubercles in ♀♀. Meso- and metasternum irregularly set with a variable number of granules or tubercles; metasternum may be smooth in ♂♂. Tegmina broadly oval and with a moderately distinct central hump in ♂♂; ± reaching posterior margin of metanotum. Alae of ♀♀ ± as long as tegmina; of ♂♂ variable, either slightly shorter than tegmina or reaching as far as abdominal segment VI. Anal region reticulate with distinct brown to black radial and transverse veins, translucent pink or red in ♂♂. Abdomen considerably longer than head and thorax combined. Median segment longer than metanotum, smooth. Segments II–VII distinctly longer than wide. Tergites unarmed in ♂♂, II–V often with a ± distinct pair of posterior spines in ♀♀. VII parallel-sided, with lateral margins gently rounded posteriorly, or with a small posterolateral lobe or tooth. VIII and IX narrower (♀♀) or slightly wider (♂♂) than previous segments. Sternites II–VII smooth. Praeopercular organ of ♀♀ formed by a ± distinct, elongate and longitudinal wart-like median tubercle close to posterior margin of sternum VII ( Figs. 288–289 View FIGURES 287 – 289 ). Anal segment with a longitudinal median carina and the posterior margin with a ± distinct median notch; tapered in ♀♀. Epiproct very small in ♂♂, triangular or shield-shaped and ± projecting beyond anal segment in ♀♀. Vomer of ♂♂ well developed, broadened basally and with an elongate, ± papillate terminal hook ( Figs. 304–310 View FIGURES 301 – 309 View FIGURES 310 – 314 ). Cerci straight, small and tapered in ♀♀, obtuse, about as long as anal segment and cylindrical in ♂♂. Poculum of ♂♂ convex, cup-like, often longitudinally carinate and with a blunt hump or spine basally. Subgenital plate of ♀♀ long, ± lanceolate with the apex narrow and ± pointed; projecting over apex of abdomen by at least the combined length of tergites IX and X. Legs of moderate length, pro- and mesofemora shorter than mesothorax in ♀♀, about as long or a little longer in ♂♂. Hind legs ± reaching (♂♂) or clearly not reaching (♀♀) to the apex of abdomen. Two outer ventral carinae of meso- and metafemora each with 1–3 sub-apical spines, the medioventral carina of these femora with a longitudinal row of 4–7 ± distinct spines. Dorsal carinae of all femora unarmed, those of the meso- and metafemora often forming a shallow to acutely triangular sub-apical tooth or lobe. Tibiae unarmed except for a few small teeth in the apical portion of the medioventral carina; anterodorsal carina in ♀♀ sometimes gently elevated sub-basally and sub-apically. All basitarsi slender and rather elongate, longer than following two tarsomeres combined.
Eggs: Medium-sized (capsule length 3.1–4.4 mm), capsule ovoid, round in cross-section and> 1.5x longer than wide, polar area rounded. Capsule surface minutely granulose or rugulose. Micropylar plate elongately heartshaped, the anterior end narrowed and the widened posterior end with a prominent median notch;> 2/3 as long as capsule. No median line ( Fig. 40 View FIGURES 37 – 44 ). Operculum with a prominent, raised, squamiform, hat or knob-like capitulum. Colouration of capsule variable, often prettily mottled in various shades of brown, straw, cream, grey and orange.
Differentiation: Very close to Parhaplopus n. gen. but differing by: the convex and distinctly bi-cornute vertex and anterior pair of tubercles or spines on the pronotum of both sexes; slender mesothorax and slender probasitarsus of ♀♀, as well as the reticulate anal region of the alae; larger and conspicuously thickened cerci and more convex poculum with a ± distint central spine of ♂♂. The eggs clearly differ from those of Parhaplopus n. gen. by having the capsule surface much less sculptured and possessing a ± distinct conical, hat or knob-like capitulum. For a more detailed differentiation see Table 29 View TABLE 29 .
Comments: Burmeister (1838: 576) established Haplopus as an amendment to Aplopus Gray, 1835 based on the original Greek pronounciation. This was however an unjustified emendation (ICZN, 1999: Article 32.5) and hence Haplopus is a junior objective synonym of Aplopus Gray (ICZN, 1999: Article 33.2.3). Aplopus Gray, 1835 however is preoccupied and a junior homonym of Aplopus Dejean, 1821 ( Coleoptera : Curculionidae ) and therefore replaced by Haplopus Burmeister, 1838 (Zompro, 2005a: 30) , which is an available name (ICZN, 1999: Article 19.1).
In the composition it was used by most former authors (e.g. Kirby, 1904a; Redtenbacher, 1908 or Moxey, 1972 in litt.) Haplopus Burmeister, 1838 was not a natural grouping, which had already been suggested by Rehn & Hebard (1938: 52). This is obviously seen in two clearly distinct types of eggs and several obvious distinctive features of the insects. Eggs of typical Haplopus exhibit a more or less prominently conical, knob or hat-like capitulum and have a rather faintly coriaceous capsule surface, whereas those of the second group lack a central capitulum and have the capsule surface prominently sculptured with raised ridges and humps. Species belonging to the second group are here transferred to the “ jamaicensis species-group” of Diapherodes Gray, 1835 .
One species formerly attributed to Haplopus , i.e. Haplopus dubius (Gray, 1835) , is definitely misplaced and here removed from the genus. The exact systematic position however remains uncertain (→ 5.9).
