Selenophorus parvus Darlington, 1934: 105. HOLOTYPE, male: Coamo Springs, Puerto Rico, Sept. 28, 1929, S.T. Danforth (MCZC).- Woodruff 1944: 50.- Erwin and Sims 1984: 440.- Bennett and Alam 1985: 20.- Ball 1992: 85.- Lorenz 1998: 356.- Lorenz 2005: 377.- Peck 2009: 13.

Type locality.

Coamo Springs, Coamo Municipality, Puerto Rico.

Diagnosis.

This species is readily separated from the other members of the hylacis species group by a combination of: small size and pronotum with obtuse hind angles.

Descriptive notes.

Data for SBL in Table 1. Habitus as in Fig. 25D. Clypeus with anterior margin moderately concave. Labrum with anterior margin shallowly concave. Antennae with antennomeres 1-3 testaceous, antennomeres 4-11 darker; mouthparts and legs testaceous. Dorsal and ventral surfaces rufo-brunneous to brunneo-piceous; lateral bead of pronotum paler. Head shiny, microlines not visible at 100 × in males, just visible at 100 × as isodiametric mesh pattern in females; pronotum shiny, microlines not visible at 100 ×. Elytra shiny, with mesh pattern transverse, sculpticells about 3 –4× wide as long; slightly iridescent, less than observed in S. clypealis . Pronotum with posteriolateral impressions impunctate; posteriolateral angles obtuse. Elytral striae impunctate, except the standard setigerous punctures in striae 2, 5 and 7. Males with adhesive vestiture on tarsomeres 1-4 of fore- and mid-tarsi; females without adhesive vestiture on tarsomeres 1-4 of fore- and mid-tarsi. Tarsomere 1 of fore- and mid-tarsus in females not expanded. Both males and females with four terminal setae near the posterior margin on sternum VII.

Male genitalia. Fig. 28 A–C. Apical portion of phallic median lobe moderately long, symmetrically broadly rounded in dorsal/ventral aspect; endophallus with one field of short, thin spines medially, a few scattered shorter spines near apex; without lamina; ostium anopic. Ventral surface of shaft smooth.

Ovipositor and female reproductive tract. Fig. 29B. Gonocoxite 2 falcate, with wide base. Bursa copulatrix moderately short; spermatheca (sp) moderately long, with apical portion coiled, originating near base of common oviduct; moderately long spermathecal gland duct originating well above base of spermatheca. Spermathecal gland (spg) small, bulbous, without swelling of duct basad gland.

Geographical distribution.

Fig. 30. The range of this species includes the Greater Antillean island of Puerto Rico, and the Lesser Antillean islands of Barbuda, Martinique, St. Lucia, Barbados, Bequia, Mustique, Canouan and Grenada.

Chorological affinities and relationships.

Within the species of the hylacis species group, the range of S. parvus is overlapped by the range of S. subquadratus . However, with the exception of Puerto Rico, the two species have not been recorded from the same island within their respective ranges. Relationships of S. parvus are not postulated beyond species group membership.

Material examined.

In addition to type material, we have seen a total of 5,451 specimens (2,412 males, 3,040 females). See Appendix for details.
