Parahypatropis similis sp. nov. Barros, Barão and Grazia

( Figure 9 (a ‒ c), 10(a ‒ f), 11(a ‒ c), 12(e ‒ h), 18)

Type material. HOLOTYPE 1#m, BRAZIL [Rio Grande do Sul], Canoas, Banhado Grande , 19 October 1999, Col. MCN, 53215, I. Heydrich leg. ( MCNZ) . PARATYPES, BRAZIL [Rio Grande do Sul], 2#m, Canoas, Banhado Grande , 19 October 1999, Col. MCN, 53201 <Illustrated male>; 53235 <without genital capsule>, I. Heydrich leg. ( MCNZ) .

Diagnosis. Labium reaching metacoxae. Hemelytral membrane surpassing apex of body. Connexivum concealed. Dorsal rim of pygophore concave, notched. Median excavation of superior layer of ventral rim V–shaped. Segment X subapical and apically narrower than base and projected dorsally.

Description. General colour light brown dorsally and dark brown ventrally. Antennomeres brownish. Coxae with dark brown blotches; femora and tibiae light brown with dark brown punctures; tarsi light brown. Prosterno and mesosternal carina, evaporatorium and sternites III–IV medially reddish-brown to brown; sternites III–VII light brown laterally and with shallow punctures. Body small and elongated, convex ventrally ( Figure 9 (a ‒ c)). Proportions of antennomeres I> II <III> IV <V. Labium reaching the metacoxae; proportions of labial segments I <II> III> IV ( Figure 9 (b)). Anterolateral margins of pronotum serrated along anterior half ( Figure 9 (a)). Hemelytral membranes surpassing apex of body. Connexivum concealed ( Figure 9 (a)). External scent efferent system, abdomen, spiracles and trichobothria as described for the genus. Measurements in Table 1 .

Male genitalia. Pygophore quadrangular ( Figures 10 (a ‒ f), 12(e ‒ h)); posterolateral angles somewhat explanate, apical margin sinuous (12 g ‒ h). Genital cup occupying less than half the length of pygophore. Dorsal rim of pygophore notched medially with 1 + 1 dorsal processes; extension of dorsal rim obsolete over segment X. Superior layer of ventral rim without processes; median excavation of superior layer of ventral rim V-shaped ( Figure 12 (e ‒ g)); lateral margin of projection of superior layer of ventral rim entire ( Figure 10 (a ‒ b)). Inferior layer of ventral rim without processes ( Figure 10 (d,f)). Segment X ogival, subapical and apically narrower than the base and dorsally projected ( Figure 10 (a ‒ b)). Phallus follows the pattern described for Parahypatropis occultata ( Figure 11 (a ‒ c)).

Etymology. The specific epithet similis , refers to its similar morphology to other Parahypatropis species.

Distribution. Brazil (Rio Grande do Sul) ( Figure 18).

Remarks. Parahypatropis occultata and P. similis present differences mainly in body size and labium length, colour and morphology of the male genitalia, shown in Table 1 and in Figures 6, 7, 10, 11 and 12.
