Pronotal punctures are widely dispersed in one paratype, whereas the remaining six paratypes have exoskeletal structures similar to the holotype. Distribution. This eucnemid species is known from nine specimens taken from two locations within the province of Heredia. Biology. Two specimens were taken from a primary forest. Five specimens, including the holotype were taken from a second growth forest. Larvae and pupae are unknown. Etymology. The specific epithet is named from the presence of confluent surfaces of the frons on the new species.Published as part of Otto, Robert L., Muona, Jyrki & Córdoba-Alfaro, Jim, 2023, A new genus and sixteen new species of false click beetles (Coleoptera: Eucnemidae) described from the Heredia Province of Costa Rica with several additional records from the Osa Peninsula and Panama, pp. 1-36 in Insecta Mundi 2023 (991) on pages 16-1
Isarthrus striatus Otto, Muona and Cordoba-Alfaro 2023, new species
No full textIsarthrus striatus Otto, Muona and Córdoba-Alfaro, new species Figures 35–36 Diagnosis. The new eucnemid species can be readily distinguished from any macraulacine members of Eucnemidae present in Costa Rica by the presence of an interantennal carina, a wide lateral antennal groove which is widest in the middle, simple tarsal claws and dark colored dorsum with reddish-brown antennae and legs. The new species differs from the Nearctic Isarthrus calceatus LeConte by its antennal grooves widest in the middle, striate elytra and shorter flagellomeres II–III. Isarthrus calceatus have parallel-sided antennal grooves, poorly developed striae on the elytra, and slightly longer flagellomeres II–III. Type material. Female holotype: “ COSTA RICA: Prov.

Paratypes are to be deposited in INBC and GERP. Description. Female holotype: Length, 8.5 mm. Width, 2.5 mm. Body elongate; dark brownish-black; antennae and legs dark reddish-brown; head, pronotum and elytra clothed with short, recumbent yellowish setae (Figure 35). Head: Surface somewhat shiny, subspherical with crowded punctures; frons convex with slight circular impression above interantennal carina, poorly developed median carina present; interantennal carina present; apical margin of frontoclypeal region weakly trilobed, more than 2 times wider than base; mandibles stout, bidentate, densely punctate. Antenna: Filiform from flagellomeres I–IX, attaining about 1/3 the length of the body; flagellomere I longer than wide, longer than II; flagellomeres II–III each slightly longer than wide, sub-equal, each shorter than I and IV; flagellomeres IV–V each longer than wide, sub-equal, longer than III, shorter than VI; flagellomeres VI–VIII each longer than wide, sub-equal; flagellomere IX slightly longer than VIII. Pronotum: Surface somewhat shiny, with deep, crowded punctures; quadrate, with well-developed, sharp hind angles; sides parallel-sided at basal 1/2, arcuate at apical 1/2; disc convex, slightly depressed near base above scutellar shield; base sinuous. Scutellar shield: Quadrate, sub-triangular, shallowly punctate, setose and distally rounded. Elytra: Very shallow striae present; interstices slightly elevated; surfaces shiny, closely punctate. Legs: First tarsomere as long as the combined lengths of the remaining four on meso- and metatarsi; tibiae rounded in cross section; metatarsomeres I–III simple; metatarsomere IV excavated; metatarsomere V elongate with simple claws. Venter (Figure 36): Closely punctate, with short, recumbent silver-colored setae; hypomeron with basally opened, lateral antennal grooves, widest in the middle; metepisterna parallel-sided; elytral epipleura punctate; metacoxal plates medially 3.0–6.0 times wider than laterally. Variations. Four female paratypes were examined. These paratypes measured 7.0– 8.5 mm long and 2.0– 2.5 mm wide. One female paratype is as large as and just as wide as the holotype. The remaining three paratypes are shorter and narrower than the holotype. Median carina on the frons are evident in two paratypes and absent in the other two paratypes. Distribution. This eucnemid species is known from five specimens taken from La Selva within the province of Heredia. Biology. Two paratypes were taken from a primary forest. Three specimens were taken from a Malaise trap. Larvae and pupae are unknown. Etymology. The specific epithet is derived from the presence of well-developed striae on the elytra which serves as one of the best feature to distinguish the new species from the Nearctic I. calceatus.Published as part of Otto, Robert L., Muona, Jyrki & Córdoba-Alfaro, Jim, 2023, A new genus and sixteen new species of false click beetles (Coleoptera: Eucnemidae) described from the Heredia Province of Costa Rica with several additional records from the Osa Peninsula and Panama, pp. 1-36 in Insecta Mundi 2023 (991) on pages 18-2

Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Pronotum: Surface dullish, with somewhat elongate, yellow recumbent setae; punctures deep, closely spaced, almost rugose; longer than wide, with moderate, sharp hind angles; sides subparallel, sinuous; disc convex; base sinuous. Scutellar shield: Somewhat shiny, setose, punctures deep, close, subtriangular and distally rounded. Elytron: Convex, elongate, gradually narrowed from humeri to apices; conjoined tightly at apex; somewhat shiny, with elongate, yellow recumbent setae; length 2.0 mm, width 0.375 mm at humeri; humeri with punctate striae; disc with punctate striae; interstices slightly elevated, transversely rugose; apices without cavities. Legs: Femora and tibiae dark brown; tarsi dark reddish brown; surface somewhat shiny; punctures shallow, with yellow recumbent setae. Venter (Figure 38): Dark brown; surface somewhat shiny, with elongate, yellow recumbent setae; punctate, except along lateral side of hypomeron. Aedeagus (Figure 39): Elongate, dorsally flattened, sinuate, apically narrowed; median lobe free, short, apically rounded; parameres apically elongate, rounded, longer than median lobe, with lateral tooth; secondary lateral lobe absent; basal piece elongate, apically rounded. Female allotype (Figure 40): Length, 4.0 mm. Width, 1.0 mm. Antennae filiform, about 1/3 the length of the body; flagellomere I longer than wide, longer than II; flagellomere II–IV slightly longer than wide, sub-equal; flagellomeres V–VIII each slightly longer than IV, longer than wide, sub-equal. Antennae reddish-brown. Legs reddish brown. Lateral antennal grooves deeper, surfaces smooth, ridge medially undefined. Distribution. This new eucnemid species is known from two localities at La Selva (successional plot and primary forest) within Costa Rica. Biology. The holotype was taken from a successional plot. The allotype was taken from a primary forest. Larvae and pupae are unknown. Etymology. The specific epithet is derived from the dark brown coloration of the beetle.Published as part of Otto, Robert L., Muona, Jyrki & Córdoba-Alfaro, Jim, 2023, A new genus and sixteen new species of false click beetles (Coleoptera: Eucnemidae) described from the Heredia Province of Costa Rica with several additional records from the Osa Peninsula and Panama, pp. 1-36 in Insecta Mundi 2023 (991) on pages 21-2
