Pterygodermatites (Paucipectines) elegans ( Travassos, 1928)
( Figs. 1–3 View FIGURE 1 View FIGURE 2 View FIGURE 3 )
Females (7 specimens): robust body, whitish colour, 5.81 (3.01–7.62) in length and 930 (870–100) in width at the oesophageal-intestinal junction. Buccal capsule 26 (23–29) long and 23 (18–28) wide ( Fig. 2A, B View FIGURE 2 ). Oral opening is surrounded by 14–15 denticles ( Fig. 2B View FIGURE 2 ). Larger oesophageal teeth 10 (9–11) long ( Fig. 2B View FIGURE 2 ). Nerve ring and excretory pore located 690 (620–770) and 153.71 (109.63–197.80) from anterior end, respectively ( Fig. 1 View FIGURE 1 ). Muscular portion of oesophagus 91.85 (75.04–108.67) long and 30.5 (27.91–33.81) wide; glandular portion 1.32 (1.22–1.41) long and 54.56 (52.97–56.16) wide ( Fig. 1 View FIGURE 1 ). Two subventral rows with 72 cuticular projections, 42 (41–42) prevulvar combs and 30 (29–31) postvulvar spines, last spine located 108.6 (87.2–130) from posterior end ( Fig. 3C View FIGURE 3 ). Level of transition from combs and spine is anterior to vulvar opening ( Fig. 1 View FIGURE 1 , 3A, 3B View FIGURE 3 ). The oesophageal-intestinal junction opens at level of the 32nd (20–34) cuticular projection. Simple vulvar opening, with small transversal cuticular striations, situated at 1.63 (1.3–2.3) from anterior end, at level of the 41st cuticular projection ( Fig. 1 View FIGURE 1 ). The vulva is posterior to the oesophageal-intestinal junction ( Fig. 1 View FIGURE 1 ). Embryonated eggs 24 (17–32) long and 16 (11–21) wide ( Fig. 2C View FIGURE 2 ). Conical tail, anus 100 (790–122) from posterior end ( Fig. 3C View FIGURE 3 ). Caudal appendix 26 (26–27) long ( Fig. 3C View FIGURE 3 ).
Material examined
Host: Eumops sp. ( Molossidae ).
Prevalence and intensity: 33.33% (2 positives of 6 analysed). Parasites found in small intestine.
Specimens analysed: Seven voucher females, CHIOC 38600.
Locality: Brazil: state of Espírito Santo: county of Serra: Carapebus Beach (20°7’46”S, 40°18’29”W); county of Colatina: Downtown Colatina (19º 32’ 22” S, 40º 37’ 50” W).
Remarks. Pterygodermatites (P.) elegans was described by Travassos (1928) based on specimens collected from Eumops perotis Schinz, 1821 , from the state of São Paulo.
The specimens found in the present study match the general characteristics of the original description ( Travassos, 1928), including total length, number of prevulvar cuticular processes, vulva posterior to the oesophageal-intestinal junction and differentiation of the cuticular processes anterior to the vulva. Therefore, we hereby extend the known distribution range of P. (P.) elegans to include the state of Espírito Santo.
The most similar species to P. elegans and to the specimens found in our study is the recently described Pterygodermatites (Paucipectines) andyraicola Cardia et al., 2015 , which presents similarities in the position of the vulva, oesophagus length and number of pre-vulvar processes, besides sharing the host genus ( Eumops ). However, it contrasts with these specimens in body length (8.3 mm), differentiation of cuticular processes (posterior to the vulva) and number of denticles (34).
