A New Species

A new species of Tricorythopsis is described, illustrated and diagnosed based on nymphs from Pará state, Brazil. Tricorythopsis similis sp. nov. is related to Tricorythopsis rondoniensis (Dias, Cruz & Ferreira) based on abdominal terga III–VII with acute tubercles medially located on posterior margins, and by the absence of the transversal line on operculate gill. However, the new species can be identified by the following combination of characteristics: general coloration yellowish brown, with blackish and purplish marks irregularly distributed; maxillary palp 1-segmented; segment II of labial palp shorter than segment I and longer than segment III; femora and tibiae with margins covered by long, pectinate setae; tarsal claws with 4 to 5 marginal denticles and 4+2 very small, submarginal denticles. This is the first species of Tricorythopsis recorded from Pará state.

The structure and innervation as determined by methylene blue techniques of the sensilla of the maxillary palp, galea, mandible, labrum, and labial palp of the spruce budworm larva are described, based on light and scanning electron microscopy. An attempt is made to identify the function of various sensilla by comparing them with those of other insects. The function of the gustatory sensilla on the galea and epipharynx is confirmed electrophysiologically.

Morphological Differences

The egg of Paederidus ruficollis (Fabricius, 1781) and larvae of that and P. rubrothoracicus carpathicola Scheerpeltz, 1957 are described and illustrated. This is the first thorough description of immature stages for the genus Paederidus Mulsant & Rey (1878). The immature stages were obtained by rearing adults. Morphological differences between instars of the same species and also between the studied species are found in the detailed structure of the antenna, nasale, maxillary palp, labial palp, tarsungulus and urogomphus; chaetotaxy of pronotum, profemur and protibia; proportions of same body parts; microstructure of urogomphus and body colour. Comparative characters of larvae of two subtribes Paederina and Stilicina are presented.

One New Species

The fauna of bristletails of the family Machilidae in Kazakhstan currently includes one species of the genus Silvestrichiloides Mendes, 1990 and 13 species of the genus Allopsontus Silvestri, 1911. The present study describes one new species of the genus Silvestrichiloides (S. berkarensis Kaplin, sp. nov. from South Kazakhstan) and two new species of the genus Allopsontus (A. (Kaplinilis) nigrostriatus Kaplin, sp. nov. and A. (Machilanus) perfectus Kaplin, sp. nov. from Southeastern Kazakhstan). Silvestrichiloides berkarensis sp. nov. differs from the other species of this genus in the structure of antennal flagellum, apical palpomere of labial palp and ovipositor. Among species of the subgenus Kaplinilis Mendes, 1990, A. nigrostriatus sp. nov. belongs to a group of species characterized by numerous short chaetae on the ventral surface of the 5–7th palpomeres of the male maxillary palp and by the absence on the labial palp. This group includes two species: A. volgensis Kaplin, 1999 from Samara Region and A. smelyanskii Kaplin, 1999 from Orenbourg Region (both Russia). The new species differs from A. volgensis and A. smelyanskii in the length of the body and antenna, color of scales on the upper surface of the body, shape of the compound eye and paired ocellus, structure of the flagellum and apical palpomere of the male labial palp. The subgenus Machilanus Silvestri, 1934 is represented only by A. bitschi Wygodzinsky, 1962 from Afghanistan and A. perfectus sp. nov., which are characterized by numerous short chaetae on the ventral surface of the 2nd–7th palpomeres of the male maxillary palp. Allopsontus perfectus sp. nov. differs from A. bitschi in the shape of compound eyes, paired ocellus, structure of male labial palp and genitalia.

The Family

Three unusual nymphs of Euthyplociidae, subfamily Euthyplociinae, are described from Ecuador. A new genus and new species are established to accommodate these individuals. The morphologically unique specimens are defined by the following characters: short, stout tusks lacking spine-like setae but densely covered with long, hair-like setae; head almost as long as wide; long, quadrate clypeus with acute apicolateral projections; apex of 3rd segment of labial palp acute; apex of 3rd segment of maxillary palp acute and narrow. The hind wing is small, similar to that of Mesoplocia. An ongoing study of the phylogeny of the family recovers Dasyplocia gen. nov. as closely related to Euthyplocia and Mesoplocia.

A new genus and new species of Atalophlebiinae, Klugephlebia kodai Selvakumar, Subramanian & Sivaramakrishnan, are described based on male and female imagos and larvae from Palni hills of the southern Western Ghats of India. The imago of Klugephlebia gen. n. can be differentiated from all other genera of Atalophlebiinae by having the combination of vein MP forked slightly less than half of the distance from base to margin, MP2 attached at base to vein MP1 by a crossvein, a distinctive shape of the hindwing, dissimilar claws on each leg, and distinctive genitalia structures. The larva can be distinguished from other Atalophlebiinae larvae by having the combination of gills present on abdominal segments 1–7, dorsal and ventral portions of lamellae of gills 1 slender and lanceolate with branched tracheae, dorsal and ventral portions of lamellae of gills 2–7 wider & lanceolate and long & suddenly tapering at apex, fore and mid femora with regular rows of long thin setae on outer margins, denticles on claws progressively larger apically, a distinctive labrum, the maxillary palp short with long setae on third segment, and the third segment of the labial palp with distinct setation. The larvae cling to the underside of boulders in the middle of streams where the boulders lie amidst sand and silt. Updated keys to the genera of south Indian Leptophlebiidae are provided.

A New Species

A new genus of Baetidae, Pedicelliopsgen. nov., and a new species, P. capillifersp. nov., are described from Guinea (West Africa) based on larvae. The new genus is characterized by having strongly enlarged pedicelli and very short flagella, a brush of dense, short setae between prostheca and mola of both mandibles, a small rectangular labrum, an apicolaterally pointed maxillary palp, a labial palp with a small distolateral protuberance and long setae ventrally on glossae and paraglossae. The femora of all legs are covered with numerous long, fine setae. The patellotibial suture is absent on the fore tibia and present on middle and hind tibiae. The claw is pointed with two rows of denticles. No spines are present on the posterior margins of the abdominal tergites. The imago remains unknown and the relationships with other African genera of Baetidae remains tentative. Despite being easily identifiable and of a fairly large size (body length ca. 5 mm), only two larvae were found in two highly sampled localities in West Africa.
