Diagnosis.
Paracondeellum paradisum sp. nov. is characterized by two pairs of A -setae on tergite I, one pair of A -setae, and eight pairs of P -setae on tergites II–VI, absence of A -setae and P2a seta on tergite VII, tergites IX and X with 12 and 10 setae, respectively, absence of seta d4 on dorsal side of head, and female squama genitalis short, with conical acrostylus.
Material examined.
Holotype, female (slide no. HN-SY-P2017016) (SNHM), China, Hainan, Sanya City, Yalong Bay Tropical Paradise Forest Park, soil of the tropical rain forest, 200 m elev., 18.25°N, 109.63°E, 22-III-2017, Y. Bu collector. Paratypes, 1 female (slide no. HN-SY-P2017071) (SNHM), same data as holotype.
Description.
Holotype: body length 570 μm, yellow-brown, foretarsus darker ( Fig. 4A View Figure 4 ).
Head. Elliptic, length 80 μm, width 50 μm ( Fig. 2A View Figure 2 ). Head setae short, rostrum slightly protruded. Setae d6 and sd6 present, d4 and sd4 absent, d6 and d7 length 6 μm and 7 μm respectively. Pores cp and fp present. Pseudoculus oval, without lever, length 8 μm, width 6.5 μm. PR = 10 ( Fig. 2B View Figure 2 ). Canal of maxillary gland short, with globular calyx and short sausage-like posterior dilation. CF = 10 ( Figs 2C View Figure 2 , 4B View Figure 4 ). Labial palpus well developed, with four setae and apical tuft, without basal sensillum ( Fig. 2D View Figure 2 ). Maxillary palpus with two subequal seta-like sensilla ( Fig. 2E View Figure 2 ).
Foretarsus. Length 31 μm, claw length 9 μm, TR = 3.4; empodium length 2 μm, EU = 0.22. Dorsal sensilla t-1 and t-2 slender and long, BS = 0.63; t-3 short and spatulate, not reaching base of claw ( Fig. 2G View Figure 2 ). Exterior side with only sensilla a, b and f present; a spatulate, b and f short ( Fig. 2F View Figure 2 ). Interior sensilla a’ and c ' short sward-like, b ' absent. Relative length of sensilla: t-2> t-1> c'> t3> a> a'> (b = f) ( Fig. 2F, G View Figure 2 ). Length of middle tarsus 15 μm; claw length 10 μm. Length of hind tarsus 17 μm; claw length 12 μm.
Thorax. Thoracic chaetotaxy given in Table 2 View Table . Setae 1 and 2 on pronotum subequal in length, 6 μm and 7 μm respectively ( Fig. 2H View Figure 2 ); mesonotum with seven pairs of posterior setae, P5a minute; metanotum with six pairs of posterior setae, P5a absent; setae P1, P1a, P2 on mesonotum 6 μm, 1 μm, 7 μm, respectively; P1a on meso- and metanotum short, pin-shaped ( Fig. 2H View Figure 2 ). Prosternum without seta A2. All setae on thoracic sternites of normal shape. Pores on thorax not observed.
Abdomen. Abdominal chaetotaxy given in Table 2 View Table . Tergite I with two pairs of anterior setae (A1, A5) and six pairs of posterior setae, A5 short, sensillum-shaped ( Fig. 2I View Figure 2 ). Tergites II–VI with one pair of anterior (A1) and eight pairs of posterior setae, P2a present and P3a absent ( Figs 2J View Figure 2 , 3A View Figure 3 , 4E, F View Figure 4 ). Tergite VII without anterior setae and with eight posterior setae, P2a absent and P3a present ( Figs 3B, C View Figure 3 , 4E, F View Figure 4 ). Accessory setae P1a on tergites I–V short pin-shaped (4 μm), on tergites VI–VII normal (5 μm). Accessory setae P2a and P4a always pin-shaped, 2 μm in length. P3a on tergite VII of normal shape and 5 μm long ( Fig. 4E, F View Figure 4 ). Tergite VIII with two pairs of anterior setae (A1, A3) ( Fig. 4C View Figure 4 ). Posterior central seta Pc present on sternites IV–VII, sensillum shaped, 4-5 μm long ( Figs 3A, C View Figure 3 , 4F View Figure 4 ). P1a on sternites IV–VI short, pin-shaped ( Fig. 3A View Figure 3 ), on sternite VII setiform ( Fig. 3C View Figure 3 ).
Tergites I–VII with pores psm and al ( Fig. 2I, J View Figure 2 ), VIII with pores psm only, IX–XI without pores, XII single median pore. Sternites I–VI each with single posteromedial pore spm ( Figs 3A View Figure 3 , 4F View Figure 4 ), VII with three posteromedial pores ( Figs 3C View Figure 3 , 4F View Figure 4 ), VIII with single posteromedial pore ( Fig. 4D View Figure 4 ), IX–XI without pores, XII with one pair of anterolateral sal pores.
Abdominal appendages typical of the genus. Subapical setae and apical setae on appendage III 11 μm and 5 μm long respectively. Striate band on abdominal segment VIII reduced to a single serrate line ( Fig. 4D View Figure 4 ). Comb on abdomen VIII rectangular, with 10 teeth, 10 μm wide ( Fig. 2K View Figure 2 ). Female squama genitalis short, with conical acrostylus ( Fig. 2L View Figure 2 ).
Etymology.
Latin “paradisum”, after "Paradise Forest Park" where type specimens were collected.
Distribution.
China (Hainan)
Remarks.
The genus Paracondeellum Yin, Xie & Zhang, 1994 is endemic to China and was previously known by a single species, P. dukouense , from Sichuan and Yunnan provinces. Paracondeellum paradisum sp. nov. differs from P. dukouense in the shape of foretarsal sensilla, pseudoculus, and female squama genitalis, and in the body chaetotaxy. A comparison of the morphology of these two species is given in Table 4 View Table .
