A new species of Tapinella Enderlein, 1908 (Insecta: Psocoptera) from French Guiana, North Amazon rainforest

: A new species of Tapinella Enderlein, 1908 was described from French Guiana – T. montjoliensis n. sp. It was collected near Montjoly Town and Wayki Village. The species was found in a plantation and a village from dry banana ( Musa sp.) leaves, and among river bank scrubs from dry leaves of various bushes.

No any species from the family Pachytroctidae were known from the Guianas till now.In this paper I describe a new species of Tapinella Enderlein, 1908 (Pachytroctidae) from French Guiana, a genus which contains mainly tropical species and is not studied in detail in the entire area of Equatorial America.

Material and methods
Psocoptera were collected from French Guiana by beating the vegetation between 29.07-03.08.2023.The specimens were stored in 96% ethanol.The photos (specimens in glycerin) were taken by a camera Canon PowerShot SX500IS through the eyepiece of a light microscope Optika.The material was deposited at the National Museum of Natural History, Sofia, Bulgaria (NMNH), Natural History Museum of Geneva, Switzerland (NHMG) and the collection of the author.The species discussed in the paper were considered according to original descriptions.Measurements followed Lienhard (1998).
Description (after 28 days in 96% ethanol): Female: Colouration: The whole animal is blackishbrown with an exception of the base of the wings, dorsal and ventral side of the thorax, distal half of the coxae, base of the femurs, distal part of the tibias, ocelli, base of the palps, and mouth apparatus which are white or pale creamy (Fig. 1A).
Morphology: Macropterous.Three ocelli present.Lacinial tip with one long cusp and a small one having itself a small ridge at its internal side (Fig. 1C).Fore and hind wings slender with venation typical for the genus, same as in T. pictipenna Thornton, Lee & Chui, 1972(Thornton et al. 1972) (Fig. 1B).Subgenital plate with large T-sclerite having well developed stem and very long arms, more than two times longer than the stem length (Fig. 1D).
Epiproct cone-shaped, paraprocts elongated.Both with two types of setae: long and short.The long setae of the epiproct are same length like these of the paraprocts.
Male: Unknown.Diagnosis: In body coloration T. montjoliensis n. sp. is most similar with T. pictipenna Thornton, Lee & Chui, 1972 known from Indonesia (Thornton et al. 1972).The new species differs from T. pictipenna by its brown eyes (versus black), darker maxillary palps and antennae (versus very pale buff) and lack of wide dark grey longitudinal band at each side of the abdomen and between the compound eye and the antennal socket (only slight dark patches present).The pigmentation of the forewing of the new species is more evenly distributed, and only by a particular light a slight darkening can be observed near the hyaline basal zone.In addition the arms of the Tsclerite compared to its stem are longer in T. montjoliensis n. sp.(more than two times than the stem length).The ratio IO/D in the new species is about two times lower that this in T. pictipenna (2.1 vs 4.5).
Etymology: Named after the Montjoly Town, French Guiana, at which vicinities the species was firstly found.
