Hainanphasma diaoluoshanensis View in CoL Ho spec. nov.
( Figs. 7–9, 11 View FIGURES 1 – 11 , 14, 16 View FIGURES 12 – 18 )
Type. Holotype: Ƥ, Diaoluoshan National Nature Reserve, Lingshui Country, Hainan Province, China, 6.VII.2011, George Ho Wai-Chun (SYSBM, ex coll. GH).
Diagnosis. This species is similar to Hainanphasma cristata Ho gen. nov. spec. nov., but can be differentiated by its smaller size, three elevations on outer edge of the first antennal segment, meso- and metafemora with semicircle armature and with one lamella on dorsal carina of metatibiae.
Description. Female ( Figs. 7–9, 11 View FIGURES 1 – 11 , 14, 16 View FIGURES 12 – 18 ). Smaller and less robust than H. cristata Ho spec. nov. Body rough, tuberculate and punctulate. Covered with minute setae throughout the body. Head, pronotum, mesosternum, metasternum, ventral surface of abdomen and legs brown. Mesonotum mainly grayish brown. Metanotum grayish brown with a brown longitudinal band. Dorsal surface of abdomen grayish brown, with a brown longitudinal band running from median segment to fifth abdominal tergum.
Head: Oval. Vertex with a pair of triangular tubercles behind the bases of the first antennal segment and following with a spine-like tubercle; the anterior paired tubercles about 3 x larger than the posterior pair. Occiput conically elevated with a crest, consisting out of four distinct carinae, surfaces slightly punctulate, dorsal carinae with granules and tubercles, apex of the crest slightly emarginate. Eyes rounded, rufous brown. Genae with a short postocular carina. Antennae brown, with darker apices and mottlings on some segments, not surpassing apices of protarsi, with 24 segments. The first segment broad, triangular in cross section, with distinct median carina, slightly as long as the combined length of third and fourth segment, outer edge with two spine-like tubercles placed before middle and with a rounded tubercle placed at the middle. Second segment slightly shorter than third segment; apical segment as long as the third segment, very setose. Fourteen segment with a minute black spine on dorsal surface, pointing anteriorly.
Thorax: Pronotum square, as long as wide, with an elevation surrounded by four short blunt spines before a transverse sulcus and with two short longitudinal carinae placed behind the transverse sulcus. Posterior margin with six small granules, the median pair placed at the end of the two longitudinal carinae. Mesonotum parallelsided, anterior margin carinate and broadly incurved, median carina indistinct. Lateral margins carinate with a row of minute pits. Antero-lateral angles of the mesonotum with a small granule. Mesopleura with four small granules marginally. Metasternum with few small granules. Metanotum about 2 x shorter than mesonotum, with nine to thirteen small pits along lateral margins and with a pair of small anterior granules.
Abdomen: Median segment with two posterior granules and few small pits along lateral margins. Sixth and seventh terga with two black depressions. Second to eighth terga with few small pits near lateral margins; with xshaped carina medially, strongly elevated at fifth tergum. Ninth tergum with a crest-like structure medioposteriorly, margin of the crest unarmed, apex slightly emarginate, almost reaching the end of the anal segment. Anal segment rectangular, with one granule near lateral margins, posterior margin slightly emarginate. Subgenital plate rounded, not projecting over the end of the anal segment, medially carinate, with granules near the posterior region, posterior margin truncate and thick-built. Cerci invisible, presumably very small and flattened as in Hainanphasma cristata Ho spec. nov.
Legs: Short and thick. Profemora as long as mesofemora, curved basally, all carinae with two to three indistinct lamellate elevations. Dorsal carinae of protibiae with two indistinct lamellate elevations. Antero-dorsal carina of mesofemora with one small lamella basally. Postero-dorsal carina of meso- and metafemora with three distinct lamellae, median one as large as posterior one and larger than anterior one. Antero-ventral carina of meso- and metafemora with two spine-like tubercles subapically. Postero-dorsal carina of meso- and metatibiae with one small lamella medially.
