HT, ♂: Cayman Islands: Cayman Brac, Bight Road at Maj. Donald Rd., 24-V-2009, coll.: R. H. Turnbow [FSCA]. PT, ♂: Cayman Islands: Cayman Brac, Bight Road at Maj. Donald Rd., 24-V-2009, coll.: R. H. Turnbow [FSCA]. PT, ♀: Cayman Islands: Cayman Brac, Bight Road at Maj. Donald Rd., 24-V-2009, coll.: M. C. Thomas [FSCA].
Diagnosis: Very close to H. scabricollis (Gray, 1835) but differing by: the averagely smaller size; smaller and blunt horns of the head (Figs. 281–282); relatively larger eyes and lack of a sub-apical dorsal tooth on the meso- and metafemora; lack of a sub-basal tooth on the anterodorsal carina of the meso- and metatibiae; slightly longer tegmina and alae, the first distinctly projecting over the posterior margin of the metanotum and the latter in ♀♀ reaching about half way along the median segment with the anal region not distinctly red as in H. scabricollis. ♀♀ also differ by the slender probasitarsus, differently shaped anal segment and much smaller, triangular epiproct (Fig. 283). ♂♂ can be distinguished from those of H. scabricollis by: the lack of a white longitudinal marking along the lateral margins of the pronotum (Fig. 282) and median portion of the median segment; lack of a posterolateral tooth or lobe of abdominal tergum VII (Fig. 285); club-like, much more prominently swollen and broadened abdominal segments VIII–X (Fig. 285); shorter and dorsally globose anal segment (Fig. 286); smaller but conical basal projection of the poculum (Fig. 286) and differently shaped vomer, which has the terminal hook considerably shorter than in H. scabricollis (Fig. 355).
Etymology: This new species is dedicated to Dr. R. E. Woodruff (FSCA) for arranging loan of many specimens from the collection of FSCA and his private collection.
Description: ♀ (Fig. 279). Of medium size (body length including the subgenital plate 142.0 mm) and moderately slender for the genus; body surface slightly glabrous. General colour creamish mid brown with faint darker speckles on body. Ventral body surface with a pale greyish wash. Head with two small, elongate black markings above the eyes. Cheeks irregularly furnished with white and dark brown (Fig. 281); two small black spots on frons. Antennae greyish straw, the apical portion with three dark transverse bands, otherwise about every fourth segment with a dark apex. Eyes pale ochraceous grey. Tubercles and spines of the thorax with black points. Tegmina and costal region of alae dark brown with the venations pale cream; the latter black basally. Anal region of alae transparent with a slight pinkish wash and all major longitudinal and transverse veins marked with black.
Head: About 1.3x longer than wide and ovoid with the cheeks moderately convex. Vertex rounded and armed with a pair of moderately sized, blunt and conical cephalad tubercles (Fig. 281). A further pair of small acute granules posteriorly. Eyes circular and contained about 1.8x in length of cheeks. Antennae almost reaching posterior margin of median segment; consisting of 61 segments. Scapus about 2x longer than wide and slightly constricted towards the base. Pedicellus roughly half the length of scapus and 2/3 the length of III.
Thorax: Pronotum longer but narrower than head, almost 2x longer than wide, roughly rectangular and with the lateral margins roundly emarginated medially. Transverse median sulcus rather decided, gently curved and not reaching lateral margins of segment. Dorsal surface with a two pairs of minute spines in the anterior portion and a pair of small spines near posterior margin; otherwise with a variable number of small rather irregularly disposed tubercles (Fig. 281). Anterior margin raised and with four spiniform tubercles. Mesothorax about 2.6x longer than head and pronotum combined. Mesonotum very slightly gradually widened towards the posterior and with a fine but acute longitudinal median carina; surface sparsely set with irregularly disposed small, spiniform tubercles and two pairs of small spines in anterior portion. Lateral margins with a marginal row of 10–12 spiniform tubercles. Meso- and metapleurae armed with an irregular longitudinal marginal row of small but pointed spines. Mesosternum with a few scattered granules and metasternum smooth except for two very small granules medially. Tegmina oval, coriaceous, with the venation very distinct, dense and irregularly disposed; reaching about ¼ along median segment. The median protuberance very shallow and conspicuously displaced towards the apex of tegmen. Alae a little shorter than tegmina and reaching only about half way along median segment.
Abdomen: Median segment about 1.7x longer than wide and very gently widened towards the posterior. All segments unarmed, except for a pair of small posteromedian spines on tergum II. Segments II–VI roughly equal in length and width, all rectangular and about 2x longer than wide. Tergum VII slightly shorter and narrower than previous, about 2.2x longer than wide with lateral margins very slightly deflexed posteriorly. Praeopercular organ formed by a rounded sepia-coloured tubercle, which posteriorly extends into a longitudinal furrow, leaving a median gap in the posterior margin of sternum VII. Tergum VIII slightly shorter than VII, narrowed mediallly, almost 3x longer than wide and 2.5x longer than IX. IX roughly rectangular. Anal segment with a very faint longitudinal median carina, the posterior margin slightly deflexed, broadly rounded and with a small posteromedian indentation. Epiproct very small, triangular (Fig. 283). Cerci very small, conical and with an acute tip; not reaching to posterior margin of anal segment. Subgenital palte very long, lanceolate, longitudinally keeled over entire length and with a narrow but rounded apex; extending over abdomen by almost the combined length of tergites VIII–X (Figs. 283–284).
Legs: Profemora about 4/5 the length of mesothorax, mesofemora slightly projecting over posterior margin of median segment and metafemora reaching about half way along abdominal segment IV. Profemora unarmed.
Anteroventral carina of meso- and metafemora with two, posteroventral carina with one sub-apical spine; medioventral carina armed with 4–6 pointed and fairly strong spines. Both dorsal carinae of meso- and metafemora smooth but very gently elevated sub-apically. All tibiae unarmed. Basitarsi roughly equal in length to following three tarsomeres combined.
♂ (Fig. 280). Fairly small (body length 76.4–80.0 mm) and stocky for the genus with conspicuously shortened alae (length 4.7–5.5 mm). General colour of dorsal body surface pale ochre with a greenish hue. Head, meso- and metapleurae, most of ventral body surface and legs green. Lateral margins of abdominal tergites II–VII each with a white anterior marking, largest on II and gradually decreasing in size towards VII (Fig. 280). Tergites VIII and IX with entire lateral margins broadly white and anal segment with a small white marking anterolaterally. Points of thoracal spines black. Eyes pale reddish brown, antennae ochre with a slight reddish wash in basal portion. Tegmina greenish cream in central portion with the anterior and posterior margins broadly white. Costal region of alae greenish cream interiorly, whitish anteriorly and black towards the base. Anal region transparent with a slight pinkish wash and all major longitudinal and transverse veins marked with dark black. Tarsi pale brown.
Head: Generally as in ♀♀ but eyes much more prominent, projecting hemispherically and their length contained only about 1.1x in that of cheeks. Vertex smooth except for the two small, blunt cephalad tubercles (Fig. 282). Antennae moderately robust and slightly projecting over abdominal segment II; otherwise as in ♀♀.
Thorax: Pronotum slightly longer and about as wide as head, general shape as in ♀♀; surface smooth except for one (paratype) or two (holhotype, Fig. 282) moderate pairs of spines in the anterior portion. Probasisternum smooth. Mesothorax about 2.4–2.5x longer than head and pronotum combined. Mesonotum with 6–8 paired spines of moderate size in the anterior 2/3; the one (holotype, Fig. 282) or two (paratype) pairs near anterior margin largest. Mesosternum smooth except for 2–4 green granules in anterior portion and occasionally a further small pair of granules medially; metasternum smooth. Mesopleurae with a few small granules in anterior portion, metapleurae smooth. Tegmina broadly oval and very slightly projecting over posterior margin of metanotum, central protuberance very shallow. Alae small, slightly shorter than alae and almost reaching half the way along median segment.
Abdomen: Segments II–V roughly equal in length and about 3.3x longer than wide. VI and VII decreasing in length with VII no more than 2.3x longer than wide; posterior portion of tergum VII very gently widened. All tergites and sternites smooth. Tergites VIII–X conspicuously swollen and about 1.7x broader than previous segments (Fig. 285). VIII about ¾ the length to VII, trapezoidal and strongly widening towards the posterior. IX about equal in length to VIII and gently narrowed towards the posterior. Anal segment shorter than IX, roundly rectangular with the dorsal surface roundly convex (Fig. 286). Posterior margin broadly rounded with a very shallow median indentation (Fig. 285); slightly swollen and on ventral surface armed with several small, black incurving denticles. Epiproct very small. Vomer with a broad base and a moderately elongate, conical, gently upcurving terminal hook which is about equal in length to basal portion (Fig. 363). Cerci large, obtuse and scarcely shorter than anal segment (Fig. 286). Poculum convex, cup-like with a small but acutely conical basal hump (Fig. 286).
Legs: Profemora scarcely shorter than mesothorax, mesofemora about 4/5 the length of mesothorax and metafemora reaching to anterior of abdominal segment V. All less carinate than in ♀♀ but armature generally alike. Tarsi relatively more elongate and basitarsi a little longer than following three tarsomeres combined.
Distribution: Cayman Islands (Cayman Brac: forest along Major Donald Drive) [FSCA].
