A review of Cryphocricos Signoret, 1850 (Naucoridae: Cryphocricinae) with descriptions of three new species Author Sites, Robert W. text Zootaxa 2021 2021-04-14 4958 1 72 94 journal article 7179 10.11646/zootaxa.4958.1.7 e161fdff-ea50-4837-8642-8a134f58f18c 1175-5326 4693067 95DBC2B4-D082-4D39-9815-7C3879E2BF5C Cryphocricos latus Usinger ( Fig. 19 ) Cryphocricos latus Usinger 1947 : Ann. Entomol. Soc. Amer. 40:340–341. Type repository: Snow Entomological Museum Collection ( Lawrence , USA ) . Type locality: Costa Rica : San Isidro del General , 2,000 ft. Discussion: The holotype is a brachypterous male ( Fig. 19 ) and allotype a brachypterous female. Seven brachypterous paratypes also are housed in the Snow Museum. The macropterous male and female were described by Herrera & González (2013) . Cryphocricos latus is associated with fast current, large rocks, and coarse pebbles ( Stout 1981 ). These tropical streams are subject to severe seasonal spates, which result in a high rate of downstream displacement of C. latus followed by a slow recolonization rate ( Stout 1981 ). Because the macropterous form is uncommon except in the dry season, its ability to recolonize upstream following a spate is temporally limited ( Stout 1982 ). Diagnosis: This species is similar to C. obscuratus in “all characters” but differs from it by a wider body/length ratio, length> 7 mm , and claval commissure subequal to the length of the scutellum ( Usinger 1947 ). Specimens that I have examined from Costa Rica and Panama readily conform to characteristics of both species; thus, I suspect that C. latus and C. obscuratus are conspecific. Moreover, specimens of Cryphocricos from Guatemala and Belize also are small, and those from Belize had body width/length ratios suggesting a C. latus identity, but body lengths spanned those of three species ( C. hungerfordi , C. latus , and C. obscuratus ) ( Sites et al. 2018 ); thus, considerations of conspecificity must also include C. hungerfordi .
