Pedethma malandensis Weise  

( Figs. 16a, 24a, 25a)

Description. Measurements listed in Table 1. Basal antennomeres pale, apical 3–4 antennomeres darkened. Vertex with two setiferous pores on each side between upper portion of eye forming straight line, but widely separated at middle of vertex. Supracallinal, midfrontal, and supraantennal sulci well developed. Supraorbital sulcus absent. Supracallinal and midfrontal sulci straight, supraantennal sulcus concave, bent around antennal socket. Lower part of antennal callus narrow and long, extending far between antennal socket and frontal ridge. Several large pores forming two rows along margin of eye between antennal callus and orbit. Orbit extremely narrow, 0.42 times width of antennal callus. Antennal socket situated very close to eye margin. Upper part of frontal ridge very narrow between antennal calli, no more than one­fourth width of transverse diameter of antennal socket. Lower part of frontal ridge forming almost straight angle with upper part, narrower than latter. No ridges between lower part of frontal ridge and lateral third of clypeus. Anterofrontal ridge absent. Eye ( Fig. 16a) very large and occupying over two­thirds of head as viewed from lateral perspective in males. Eye 1.87 times higher than wide. Pronotum ( Fig. 16a) brownish, darker at anterior two­thirds than region posterior of transverse impression. Posterior pronotal depression straight. Elytra ( Fig. 16a) unicolorous, pale to moderately dark brown. Abdominal venter and metasternum darker than surrounding region. Legs pale yellow­brown. Aedeagus ( Figs. 24a, 25a) symmetrical, not strongly tapering. Apex of aedeagus truncate with slight apical, medial impression and two lateral apical arms. Dorsal transverse ridges present. Aedeagus weakly curved as viewed from lateral perspective. Spermatheca unavailable for description. Tignum of paralectotype with basal sclerotization apparently unique for the genus.

Diagnostic and Other Comments. This species was described by Weise (1923:120). It is distinctive with the very large eyes, narrow frons and frontal ridge, and anteriorly narrowed antennal calli. The truncate aedeagal apex with apico­lateral arms and unique basal sclerotization of the tignum is characteristic. This species differs from P. kurandensis   by its amber body color, pale to yellow legs, reduced number of pores above the eye, and larger pronotal punctures.

Distribution. Rainforests of northeast Queensland (Map 1, locality #4).

Basal 4–5 antennomeres pale, apical antennomeres dark brown to piceous. Antennal calli pale yellow. Vertex with two setiferous pores on each side between upper portion of eye, forming straight line. Supracallinal sulcus poorly developed. Midfrontal and supraantennal sulci well developed. Supraorbital sulcus absent. Supracallinal and midfrontal sulci straight, supraantennal sulcus concave, bent around antennal socket. Lower part of antennal callus narrow and long, extending far between antennal socket and frontal ridge. A few large pores between antennal callus and orbit. Orbit extremely narrow, one­half width of antennal callus. Antennal socket very close to eye margin. Upper part of frontal ridge between antennal calli one­fifth width of transverse diameter of antennal socket. Lower part of frontal ridge forming almost straight angle with upper part, narrower than latter. No ridges between lower part of frontal ridge and lateral third of clypeus. Anterofrontal ridge absent. Eye twice as high as wide, slightly higher than distance between eyes (above antennal sockets). Pronotal shape with moderate antemedial expansion and posterior constriction. Posterior pronotal depression sinuate with slight posterior dip at middle and sides. Pronotum pale yellow. Elytra ( Fig. 15f) dark reddish­brown, appearing black. Abdominal venter and metasternum piceous. Aedeagus ( Fig. 22k) long, slightly expanded apically, but not as strongly as in P. maculata   ; without abrupt preapical constriction as in P. maculata   . Aedeagus with very slight apical, medial impression; no other ridges or impressions present. Aedeagus moderately curved as viewed from lateral perspective. Spermatheca ( Figs. 28e, 29c) abruptly curved at each end, slightly sinuate along body. Proximal and distal ends widely separated by about one­half of overall length of spermatheca.

Diagnostic and Other Comments. The very pale yellow head, pronotum, and legs, small size, dark reddish­brown elytra (appearing black), long aedeagus without any distinct impressions or anteapical constriction, and sinuate spermatheca with widely separated proximal and distal ends distinguish this species from other Pedethma species.

Pedethma suturalis Weise   ( Figs. 14a, 25c, 28j, 29f, 32a, 33c)

Description. Measurements listed in Table 1. Dimorphic antennal lengths: males have antennae approximately the length of the body with the apical antennomere widest just distal to middle; females have antennae less than two­thirds length of body and widest portion of apical antennomere is at distal one­third or distad to this point. Basal antennomeres reddish brown, apical antennomeres darker brown to piceous. Antennal calli not noticeably paler than surrounding region of head. Vertex with three setiferous pores on each side between upper portion of eye forming straight line. Supracallinal, midfrontal, and supraantennal sulci well developed. Supraorbital sulcus absent. Supracallinal and midfrontal sulci straight, supraantennal sulcus concave, bent around antennal socket. Lower part of antennal callus narrow and long, extending far between antennal socket and frontal ridge. A few large pores separate antennal callus and orbit. Orbit narrow, 0.58 times width of antennal callus. Antennal socket situated close to eye margin. Upper part of frontal ridge between antennal calli 0.29 times width of transverse diameter of antennal socket. Lower part of frontal ridge forming almost straight angle with upper part, slightly narrower than latter. No ridges situated between lower part of frontal ridge and lateral third of clypeus. Anterofrontal ridge absent. Eye 1.94 times higher than wide. Pronotal margin strongly produced anterolaterally, with bulge extending at least as far as anterior corners. Posterior pronotal depression nearly horizontal with only slight posterior dip at middle. Posterior pronotal margin moderately constricted forming a very sinuate margin. Pronotum uniformly reddish brown. Elytra ( Fig. 14a) with distinct periscutellar patch that tapers along suture. Elytral epipleura black to brown. Color of venter of abdomen piceous. Color of metasternum piceous. Aedeagus ( Fig. 25c) slightly tapering apically. Apex of aedeagus truncate, not constricted (as in P. malandensis   ). A slight longitudinal impression extending approximately one­third length of aedeagus from apex. Aedeagus thick and moderately curved from lateral perspective. Spermatheca ( Figs. 28j, 29f, 32a) broadly curved distally as in P. howdeni   , with a wide separation between distal and proximal ends. Surface sculpture of spermatheca distinctly imbricate ( Fig. 32a).

Diagnostic and Other Comments. This species was described by Weise (1923:120–121). It is a distinctively maculate species with the periscutellar maculation extending along suture to the elytral apex, and possessing widely produced pronotal margins. Less maculate forms resemble P. howdeni   , but the aedeagi differ between the two significantly. The spermathecae of both species are similar in shape, but the surface sculpturing varies: In P. suturalis   it is imbricate, in P. howdeni   it is fissate.

Pedethma weisei Lingafelter and Konstantinov   , new species ( Figs. 20, 22j, 26f)

Description. Measurements listed in Table 1. Antennae of male approximately twothirds length of body, pale at basal one­half, with apical antennomeres gradually becoming dark brown to piceous. Antennal calli slightly paler than surrounding region of head. Vertex with one setiferous pore on each side between upper portion of eyes. Supracallinal and midfrontal sulcus poorly developed, midfrontal sulcus deeper after point of bifurcation. Supraantennal sulcus well developed. Supraorbital sulcus absent. Midfrontal sulcus straight, supraantennal sulcus concave, bent around antennal socket. Lower part of antennal callus narrow and long, extending far between antennal socket and frontal ridge. A few large pores separate callus and orbit. Orbit extremely narrow, one­half times width of antennal callus. Antennal socket situated close to eye margin. Upper part of frontal ridge between antennal calli 0.63 times width of transverse diameter of antennal socket. Lower part of frontal ridge forming almost straight angle with upper part, slightly narrower than latter. No ridges situated between lower part of frontal ridge and lateral third of clypeus. Anterofrontal ridge absent. Eye 2.13 times higher than wide. Pronotum nearly rectangular with only slight antemedial bulge and posterior constriction. Posterior pronotal transverse impression slightly sinuate, short and not conspicuous (as in P. kirejtshuki   ) due to the numerous, coarse punctures surrounding it. Pronotum reddish­brown with piceous lateral margins and dark brown anterior and posterior margins. Elytra ( Fig. 20) conspicuously maculate with piceous sutural and lateral margins and a darkened periscutellar region. Otherwise reddish­brown. Abdominal venter and metasternum piceous. Aedeagus ( Figs. 22j, 26f) relatively short with ante­apical constriction and round­ ed apex with complex pattern of medial­longitudinal impressions with interior elevations running from apex to base. Aedeagus thickened and straight from lateral perspective. Spermatheca unknown (no females known for this species).

Diagnostic and Other Comments. This species has a coarsely and heavily punctate pronotum similar to P. kirejtshuki   . However, the punctures are moderately evenly spaced and not touching, in contrast to those of P. kirejtshuki   which are mostly confluent. The longitudinal aedeagal excavations and impressions, the piceous margins of the pronotum and elytra, the piceous venter with pale legs, and the nearly rectangular pronotum readily distinguish this species.

Distribution. Forests of Southeast New South Wales (Map 1, locality #16).

Etymology. The specific epithet refers to the prolific early twentieth century coleopterist, J. Weise.
